Control device and method for operating an emergency braking assistant for a motor vehicle
Methods, systems, and apparatuses are provided for operating an emergency braking assistant for a motor vehicle. A braking intervention of the emergency braking assistant is activated. The emergency braking assistant is configured to bring the motor vehicle to a standstill automatically via the braking intervention during an imminent collision with an object. An actuation of a brake pedal of the motor vehicle is detected before or during the activated braking intervention. A release of the brake pedal after the detected actuation of the brake pedal and during the activated braking intervention is detected. An actuation of an accelerator pedal is detected after the detected release of the brake pedal. The activated braking intervention is overridden or aborted due to the detected actuation of the accelerator pedal.
1 . A control device for operating an emergency braking assistant for a motor vehicle, the control device comprising:
a processor; and
a memory in communication with the processor and storing instructions executable by the processor to configure the control device to:
activate a braking intervention of the emergency braking assistant, wherein the emergency braking assistant is configured to automatically decelerate the motor vehicle via the braking intervention in the event of an imminent collision with an object;
detect an actuation event of a brake pedal of the motor vehicle before or during the activated braking intervention, wherein the detecting comprises storing an indication that the brake pedal has been actuated;
detect a release event of the brake pedal after the detected actuation event of the brake pedal and during the activated braking intervention, wherein the release event is a distinct event from the actuation event and is detected subsequent to the stored indication of the actuation event while the braking intervention remains active;
detect an actuation of an accelerator pedal after the detected release event of the brake pedal; and
override and/or abort the activated braking intervention due to the detected actuation of the accelerator pedal.
2 . The control device according to claim 1 , wherein the memory further comprises instructions executable by the processor to further configure the control device to:
override and/or abort the activated braking intervention due to the detected actuation of the accelerator pedal if the accelerator pedal has been detected within a predetermined time interval after the detected release event of the brake pedal.
3 . The control device according to claim 1 , wherein the memory further comprises instructions executable by the processor to further configure the control device to:
during the override and/or abort of the braking intervention of the emergency braking assistant:
consider a latency time between a first point in time at which the braking intervention has been activated and a second point in time at which braking of the motor vehicle by the activated braking intervention takes place and/or is implemented perceptibly for a driver.
4 . The control device according to claim 3 , wherein the memory further comprises instructions executable by the processor to further configure the control device to:
begin a predetermined time interval as soon as the latency time has ended and the release of the brake pedal has been detected; and
override and/or abort the activated braking intervention due to the detected actuation of the accelerator pedal if the accelerator pedal has been detected within the predetermined time interval.
5 . The control device according to claim 3 , wherein the memory further comprises instructions executable by the processor to further configure the control device to:
receive a sensor signal of a vehicle sensor system of the motor vehicle when the braking of the motor vehicle is implemented perceptibly for a driver by the activated braking intervention; and
define the second point in time depending on the received sensor signal.
6 . The control device according to claim 1 , wherein the memory further comprises instructions executable by the processor to further configure the control device to:
detect the actuation of the accelerator pedal due to exceeding of a predetermined accelerator pedal angle and/or accelerator pedal gradient of the accelerator pedal.
7 . A motor vehicle comprising:
the control device of claim 1 .
8 . A method for operating an emergency braking assistant for a motor vehicle, comprising:
activating a braking intervention of the emergency braking assistant;
automatically decelerating the motor vehicle via the braking intervention in the event of an imminent collision with an object;
detecting an actuation event of a brake pedal of the motor vehicle before or during the activated braking intervention, wherein the detecting comprises storing an indication that the brake pedal has been actuated;
detecting a release event of the brake pedal after the detected actuation of the brake pedal and during the activated braking intervention, wherein the release event is a distinct event from the actuation event and is detected subsequent to the stored indication of the actuation event while the braking intervention remains active;
detecting an actuation of an accelerator pedal after the detected release event of the brake pedal; and
overriding and/or aborting the activated braking intervention due to the detected actuation of the accelerator pedal.
9 . A non-transitory computer-readable medium comprising instructions operable, when executed by one or more computing systems, to:
activate a braking intervention of an emergency braking assistant of a motor vehicle;
automatically decelerate the motor vehicle via the braking intervention in the event of an imminent collision with an object, wherein the detecting comprises storing an indication that the brake pedal has been actuated;
detect an actuation event of a brake pedal of the motor vehicle before or during the activated braking intervention, wherein the release is a distinct event from the actuation and is detected subsequent to the stored indication of the actuation while the braking intervention remains active;
detect a release event of the brake pedal after the detected actuation event of the brake pedal and during the activated braking intervention, wherein the release event is a distinct event from the actuation event and is detected subsequent to the stored indication of the actuation event while the braking intervention remains active;
detect an actuation of an accelerator pedal after the detected release event of the brake pedal; and
override and/or aborting the activated braking intervention due to the detected actuation of the accelerator pedal.
