ОПИСАНИЕ

ОБЛАСТЬ ТЕХНИКИ

The present invention relates to a vehicle control system for a vehicle having a number of driver assistance systems. Furthermore, the invention relates to a corresponding method.

УРОВЕНЬ ТЕХНИКИ

Although applicable to any system that uses control algorithms with parameters, the present invention will be described in combination with vehicles, and especially with parameters of driver assistance systems in vehicles.

In modern vehicles, a plurality of driver assistance systems can be provided to assist the driver in manoeuvring the vehicle.

For example, lane assistance systems can issue driver warnings if a vehicle is about to leave a driving lane without prior use of the turn lights or even provide a steering intervention to hold the vehicle in the driving lane.

Furthermore, cruise control systems can automatically detect vehicles in front of a vehicle and automatically accelerate and/or decelerate the vehicle to keep a predefined distance between the vehicles.

Further, driver assistance systems range from automatic parking functions to fully autonomous driving of a vehicle.

To provide such driver assistance systems, a detailed model of the vehicle's surroundings has to be established in the vehicle systems. This can, for example, be done by capturing video images of the vehicle's surroundings with mono or stereo video cameras and detecting objects in the video images.

Different algorithms are used for object detection, scene classification, and the like. Such algorithms are based on a plurality of parameters which can be individually tuned to match the desired behaviour.

One possibility is to use heuristics where possible scenarios are identified by problem analysis before the implementation of the algorithm. This solution uses heuristics to treat every single scenario and is thus limited to a finite number of scenarios.

An alternative is to use offline learning, where a model of the relevant scenarios is developed by problem analysis before the implementation of the algorithm. The algorithm is then trained offline, i.e. the parameters of the algorithm are tuned offline, to the most suited values. Using the models and a finite set of data the learning of the parameters is performed using ground truth information which is provided by labelling of the data. Such an algorithm can cope with an infinite number of scenarios. But the model parameters are frozen to the values learned before the release of the algorithm into the vehicle production.

СУЩНОСТЬ

Accordingly, there is a need for a method and an apparatus which provide more versatile and flexible driver assistance systems.

This problem can be solved by one or more embodiments of the present invention in a vehicle control system and/or in a method as set forth herein.

Consequently, the present invention provides:

A vehicle control system for a vehicle having a number, i.e. one or more, of driver assistance systems, comprising a number, i.e. one or more, of sensors configured to acquire sensor data about surroundings of the vehicle, a user interface configured to display user information and acquire user input from a user, and a processing unit coupled to the sensors and the driver assistance systems and the user interface, wherein the processing unit is configured to provide one or more adapted parameters to the driver assistance systems based on acquired user input in relation to sensor data and/or one or more actions performed by the driver assistance systems.

Furthermore, the present invention provides:

A control method for a vehicle with a number of, i.e. one or more, driver assistance systems, comprising acquiring sensor data about surroundings of the vehicle, displaying user information about the sensor data and/or actions performed by the driver assistance systems, acquiring user input from a user about the sensor data and/or actions performed by the driver assistance systems, and adapting one or more parameters of the driver assistance systems based on the acquired user input.

The present invention is based on the conclusion that a driver of a vehicle is the best source of information when feedback about the actions of the driver assistance systems of the vehicle is needed.

Therefore, the present invention employs this knowledge and provides a vehicle control system with which the driver is questioned, e.g. about actions performed by the driver assistance systems, and the driver feedback is used to tune parameters of the driver assistance systems.

The questioning of the driver can be performed via a user interface which can display user information and receive user feedback. Furthermore, the processing unit adapts parameters for the driver assistance systems and transmits the adapted parameters to the driver assistance systems for future use.

The present invention provides a way of tuning the parameters of the algorithms in the driver assistance systems during the lifetime of the vehicle after the production of the vehicle.

By asking the driver for feedback and using the provided feedback to adapt the parameters of the driver assistance systems, the ground truth can be provided by the driver and the driver can influence the system performance to fit his/her needs.

The term "parameters" in this context refers to parameters of e.g. a model used by algorithms of driver assistance systems to model relevant scenarios. The parameters are hence tuned online and the new values are then used by driver assistance systems.

In a possible embodiment, the processing unit can be configured to present one or more questions about the sensor data and/or the actions performed by the driver assistance systems to the user via the user interface and to acquire user feedback about the sensor data and/or the actions performed by the driver assistance systems. By using a non-intrusive quiz to acquire feedback from the driver, interference with the driving can be minimized.

In a further possible embodiment, the vehicle control system can comprise a camera as a sensor configured to acquire image data about the surroundings of the vehicle, wherein the processing unit is configured to display possible objects detected in the image data to the user and to acquire feedback about the possible detected objects. The processing unit can be configured to adapt object detection parameters if the feedback indicates that the object was not correctly detected. Presenting the driver with a possible detected object from a camera image allows quick testing of an object detection algorithm. The object detection in one embodiment can be done by the driver assistance systems and information about the detected objects can be provided to the processing unit.

In a further possible embodiment, the actions of the driver assistance systems can comprise providing a steering intervention, and/or providing a braking or acceleration intervention, and/or controlling lights of the vehicle, especially head lights, and/or issuing a driver warning, especially a lane departure warning, and/or conducting a traffic sign detection, and/or conducting an object detection, especially a pedestrian detection. This allows the present invention to be used with different kinds of driver assistance systems.

In a further possible embodiment, the processing unit can be configured to present questions about the sensor data and/or the actions of the driver assistance systems which query whether an action performed by a driver assistance system was produced early or in time or late, and/or whether the intensity of an action performed by a driver assistance system was too high or correct or too low, and/or whether an object detected based on the sensor data was detected correctly. This allows adapting the query to the type of action performed by the driver assistance system. For example the processing unit can be configured to present questions about the reason(s) why e.g. an autonomous system was disabled by the driver or automatically was looped back to the driver. So the driver could directly "comment" on their perception of the (re)action of the autonomous driving of the vehicle.

In a further possible embodiment, the user interface can comprise a head-up display of the vehicle configured to display the user information. A head-up display presents information to a driver of a vehicle without the driver having to look away from the street.

In a further possible embodiment, the user interface can comprise a speech recognition device and/or a number of buttons and/or an image recognition device to acquire user input. This allows receiving user input from the driver in different ways, where the method can be chosen which poses the least distraction to the driver.

In a further possible embodiment, the processing unit can be configured to start interrogation of the user about the sensor data and/or the actions of the driver assistance systems if a user pushes a predefined button of the user interface and/or issues a predefined voice command and/or provides a predefined gesture. This allows questioning the driver after a function was performed by a driver assistance system if the driver indicates that he was not satisfied by the function.

In a further possible embodiment, the processing unit can be configured to adapt the parameters by respectively widening or narrowing a range indicated by a respective current parameter. Furthermore the processing unit can be configured to adapt the parameters by respectively increasing or decreasing a value of a respective current parameter. This allows flexibly adapting different parameters for different algorithms.

In a further possible embodiment, the sensors can be coupled to the driver assistance systems and the driver assistance systems can forward sensor data to the vehicle control system. This allows using all sensors in the vehicle with the vehicle control system of the present invention.

КРАТКОЕ ОПИСАНИЕ РИСУНКОВ

For a more complete understanding of the present invention and advantages thereof, reference is now made to the following description taken in conjunction with the accompanying drawings. The invention is explained in more detail below using exemplary embodiments which are specified in the schematic figures of the drawings, in which:

FIG. 1 shows a block diagram of an embodiment of a vehicle control system according to the present invention;

FIG. 2 shows a flow diagram of an embodiment of a control method according to the present invention;

FIG. 3 shows a block diagram of another embodiment of a vehicle control system according to the present invention; and

FIG. 4 shows a schematic diagram of a vehicle where an object is presented to a driver.

In the figures like reference signs denote like elements unless stated otherwise.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a block diagram of an embodiment of a vehicle control system 1-1 according to the present invention.

The vehicle control system 1-1 is connected to a driver assistance system 3-1 which provides the vehicle control system 1-1 with information about actions performed by the driver assistance system 3-1.

The vehicle control system 1-1 comprises a sensor 4-1 which acquires data 5-1 about the surroundings of the vehicle 2 in which the driver assistance system 3-1 is installed. The sensor 4-1 can be any type of sensor 4-1, like e.g. a camera, a radar sensor, an ultrasonic sensor or the like. The sensor 4-1 can also comprise any combination of the listed single sensing elements or the like and can be arranged in the driver assistance system 3-1 or the like.

A processing unit 9-1 receives the sensor data 5-1 from the sensor 4-1 and the information about actions performed by the driver assistance system 3-1. The processing unit 9-1 can then provide information to the user about the sensor data 5-1 and/or the actions performed by the driver assistance system 3-1.

The processing unit 9-1 can e.g. display questions to the driver about sensor data 5-1 or an action performed by the driver assistance system 3-1. This can e.g. be done right after the action is performed by the driver assistance system 3-1. Possible actions of the driver assistance systems can be providing a steering intervention, providing a braking or acceleration intervention, controlling lights of the vehicle 2, especially head lights, issuing a driver warning, especially a lane departure warning, conducting a traffic sign detection, and conducting an object detection, especially a pedestrian detection.

For example the processing unit 9-1 can query whether an action performed by a driver assistance system 3-1 was produced early or in time or late, whether the intensity of an action performed by a driver assistance system 3-1 was too high or correct or too low.

The questions can refer to different driver assistance systems 3-1. Possible questions refer to but are not limited to:

A lane keeping or warning, e.g. questions can be asked like "Was the previous lane departure warning undesired?", "Was the previous steer intervention too abrupt?" or the like.

With reference to an electronic brake assistance e.g. questions can be asked like "Was the brake intervention issued later than expected?" or was the brake intervention issued stronger/lighter than expected?". Other questions can make reference to an intelligent headlight control or a traffic sign assist or pedestrian detection or the like. The questions can include "Was the previous setting of High Beam to Off desired?", "Was there a pedestrian on the sidewalk?", or the like.

The processing unit 9-1 can also query whether an object 11 (see FIG. 4) detected based on the sensor data 5-1 was detected correctly. For example a section of a camera image or an image of the possible detected object can be shown to the driver on a display and he can be asked if the displayed object is in fact the type of object that was detected. For example the driver can be asked "Is the sign displayed on the display an 80 speed limit?", where the display shows a cut from the image with a sign which was just passed and the sign recognition classified, maybe wrongly, as an 80 speed limit, or "Is the displayed shape a pedestrian?", where in the display a cut from an image is displayed where the algorithm assumed a pedestrian is located.

It is clear that this list is not comprehensive and only shows exemplary questions. Other questions can make reference to any parameter or function of any electronic system in a vehicle.

The processing unit 9-1 then analyses the user input 8-1 and generates adapted parameters 10-1 for the driver assistance system 3-1 if the driver was not satisfied with a function performed by the driver assistance system 3-1 or if an object was not correctly detected.

The processing unit 9-1 can e.g. adapt the parameters 10-1 by widening and/or narrowing a range indicated by a respective parameter 10-1. In addition or as an alternative the processing unit 9-1 can e.g. adapt the parameters 10-1 by increasing and/or decreasing a value of a respective parameter 10-1.

Another possible adaption of the parameters would be a reset functionality that could be used when the resulted parameters are not fitting the driver's expectation and which would reset the parameter values to predefined values.

FIG. 2 shows a flow diagram of an embodiment of a control method according to the present invention for a vehicle 2 comprising a number of driver assistance systems 3-1; 3-2.

The method comprises acquiring, S1, sensor data 5-1; 5-2 about surroundings of the vehicle 2. After acquiring the sensor data 5-1; 5-2 user information 7-1 about the sensor data 5-1; 5-2 or about actions performed by the driver assistance systems 3-1; 3-2 e.g. based on the sensor data 5-1; 5-2 is displayed, S2 to the user. The user can react to the displayed user information 7-1 and the corresponding user input 8-1 is acquired, S3, from the user. Based on the user input 8-1 parameters 10-1; 10-2 of the driver assistance systems 3-1; 3-2 are adapted, S4. The adapted parameters 10-1; 10-2 can then be used by the driver assistance systems 3-1; 3-2 to control the vehicle.

In one embodiment displaying, S2, user information 7-1 comprises presenting questions about the sensor data 5-1; 5-2 and/or the actions performed by the driver assistance systems 3-1; 3-2 to the user.

The actions of the driver assistance systems 3-1; 3-2 can in one embodiment comprise providing a steering intervention, providing a braking or acceleration intervention, controlling lights of the vehicle 2, especially head lights, issuing a driver warning, especially a lane departure warning, conducting a traffic sign detection, conducting an object 11 detection, especially a pedestrian detection.

Furthermore, displaying, S2, user information 7-1 can comprise presenting questions about the sensor data 5-1; 5-2 and/or the actions of the driver assistance systems 3-1; 3-2 which query whether an action performed by a driver assistance system 3-1; 3-2 was produced early or in time or late, whether the intensity of an action performed by a driver assistance system 3-1; 3-2 was too high or correct or too low, and whether an object 11 detected based on the sensor data 5-1; 5-2 was detected correctly. The above lists are only exemplary and are not exhaustive.

Furthermore, in one embodiment acquiring, S3, sensor data 5-1; 5-2 about surroundings of the vehicle 2 comprises acquiring image data 5-1; 5-2 about the surroundings of the vehicle 2. Furthermore, radar data, ultrasonic data or the like can also be acquired.

If image data 5-1; 5-2 is acquired displaying, S2, user information 7-1, 7-2 can comprise displaying, S2, possible objects 11 detected in the image data 5-1; 5-2 to the user, and acquiring, S4, user input 8-1; 8-2 can comprise acquiring feedback about the possible detected objects 11.

Interrogation of the user about the sensor data 5-1; 5-2 and/or the actions of the driver assistance systems 3-1; 3-2 can e.g. begin if a user pushes a predefined button of a user interface 6-1-6-4 and/or issues a predefined voice command and/or provides a predefined gesture. This allows the user to inform the vehicle control system 1-1; 1-2 that he was not satisfied with an action of a driver assistance system 3-1; 3-2 and such to trigger the learning process.

If a parameter has to be adapted adapting the parameters 10-1; 10-2 can comprise widening and/or narrowing a range indicated by a respective parameter 10-1; 10-2 or increasing and/or decreasing a value of a respective parameter 10-1; 10-2.

FIG. 3 shows a block diagram of another embodiment of a vehicle control system 1-2 according to the present invention which is installed in a vehicle 2 with a driver assistance system 3-2.

The driver assistance system 3-2 of FIG. 3. is just exemplarily depicted as connected to the wheels of the vehicle 2, where the driver assistance system 3-2 can accelerate and decelerate the vehicle 2. It is clear that other driver assistance systems 3-2 can also be used with the vehicle control system 1-2.

In FIG. 3 the sensor 4-2 is connected to the driver assistance system 3-2 and is only indirectly connected to the vehicle control system 1-2. The sensor 4-2 can e.g. be a camera 4-2 or a radar sensor 4-2 of the driver assistance system 3-2.

The vehicle control system 1-2, and especially the processing unit 9-2, receives the sensor data 5-2 from the driver assistance system 3-2. Furthermore, the processing unit 9-2 is coupled to one or more push buttons 6-2, a heads up display 6-3 of the vehicle 2 and a microphone 6-3. The push buttons 6-2, the heads up display 6-3, and the microphone 6-3 constitute the user interface of the vehicle control system 1-2.

The processing unit 9-2 can e.g. present in the heads up display 6-3 objects which were detected by the camera 4-2 and were classified by an object classification algorithm of the driver assistance system 3-2. The driver of the vehicle 2 can then confirm e.g. via the push buttons 6-2 that the object was correctly detected or inform the processing unit 9-2 that the object was not correctly classified. The driver can also speak into the microphone 6-4 and the response can be analysed via a voice analysis algorithm in the processing unit 9-2. Alternatively or in addition (not shown in FIG. 3) the response of the driver can be detected by filming the driver and analysing his gestures.

If the object was not correctly classified the processing unit 9-2 can adapt parameters 10-2 of the driver assistance system 3-2, especially of the object classification algorithm, and provide the adapted parameters 10-2 to the driver assistance system 3-2.

The processing unit 9-2 can also present further questions about actions performed by the driver assistance system 3-2 to the driver, see explanation of FIG. 1.

Furthermore, the processing unit 9-2 can not only present the user information 7-2 on the heads up display 6-3. For example the processing unit 9-2 can present the user information 7-2 as audio explanation over an audio system of the vehicle 2 or on other displays of the vehicle 2.

As already explained in conjunction with FIG. 1 the querying of the driver can be initiated by the processing unit 9-2 right after a function of a driver assistance system 3-2 has been executed.

In addition or as an alternative the driver can also initiate the querying by pushing a respective button, issuing a respective voice command or providing a respective gesture.

In one embodiment the processing unit 9-2 is configured to adapt parameters 10-2 automatically if a driver interrupts a function of a driver assistance system 3-2 with a vehicle control action, like e.g. accelerating or braking the vehicle 2 or steering the vehicle 2.

If e.g. a cruise control system drives the vehicle 2 behind a vehicle with a defined gap between the vehicles and the driver accelerates the vehicle 2 to narrow the gap, the processing unit 9-2 can automatically set the parameter for the size of the gap to a smaller value.

The vehicle control system 1-2 can e.g. be a dedicated control unit 9-2 in the vehicle 2 which is connected to further systems of the vehicle 2 via a vehicle bus, like e.g. a CANBus, a FlexRay-Bus, a MOST-Bus, an Ethernet-Bus or the like.

Alternatively the vehicle control system 1-2 can at least in part be embodied as a computer program which can be executed in a control unit of the vehicle 2. In such an embodiment the computer program can e.g. be executed in a driver assistance system's processor together with the other software components of the driver assistance system 3-2.

FIG. 4 shows a schematic diagram of a vehicle where an object 11 is presented to a driver. In FIG. 4 a first person view from the driver seat is shown, where a heads up display is installed in the vehicle to display information on the wind shield of the vehicle.

Right of the street on which the vehicle is driving a 70 km/h (kilometers per hour) sign is visible. This sign has been detected by a camera of a driver assistance system.

To confirm this detection the vehicle control system (not explicitly shown) displays the section of the captured image in which the sign is in the head-up display together with the question "Hey driver, is this a 70 speed limit?".

The driver can then input his answer either via a touch screen, push buttons, voice commands, gestures or the like.
