Embodiment Construction
[0037] figure 1 A motor vehicle 1 according to an embodiment of the invention is shown in plan view. Motor vehicle 1 is designed in the present case as a passenger car. Motor vehicle 1 comprises a driver assistance system 2 which includes a control unit 3 . The control unit 3 may for example be formed by an electronic control unit (ECU) of the motor vehicle 1 .
[0038] Furthermore, driver assistance system 2 includes a plurality of sensors 4 which are distributed over motor vehicle 1 . For example, the sensor 4 can be designed as an ultrasonic sensor, a radar sensor, a lidar sensor, a laser scanner or a camera. In the present case, the sensor 4 is designed as an ultrasonic sensor. In this case, four sensors 4 are arranged in the front area 5 and four sensors 4 are arranged in the rear area 6 of the motor vehicle 1 . The number and arrangement of sensors 4 is arbitrary. Driver assistance system 2 can also have 12 sensors 4 . Objects 8 in the surroundings 7 of the motor ...

The invention relates to a method for maneuvering a motor vehicle (1), wherein a trajectory for maneuvering the motor vehicle (1) is determined, during the maneuvering of the motor vehicle (1) along the trajectory a notification distance (DTH) and a collision distance ( DTC), the notification distance describing the distance to the turning point of the trajectory, the collision distance describing the distance to an object (8) in the surroundings (7) of the motor vehicle (1), and based on the notification distance (DTH) and the collision distance (DTC) to determine the travel distance until the braking system of the motor vehicle (1) is actuated, wherein the corrected distance to tell (DTH) is determined in a continuous manner based on the change in the time profile of the distance to tell (DTH) k ), the corrected distance to collision (DTC k ), and based on the corrected notification distance (DTH k ) and the corrected collision distance determine the travel distance (R).
Description
technical field [0001] The invention relates to a method for maneuvering a motor vehicle, wherein a trajectory for maneuvering the motor vehicle is determined, during maneuvering of the motor vehicle along the trajectory a notification distance and a collision distance are determined, the notification distance describing the distance to a turning point of the trajectory, the The collision distance describes the distance to objects around the motor vehicle, and based on the notification distance and the collision distance, the travel distance until the braking system of the motor vehicle is actuated is determined. Furthermore, the invention relates to a control unit for a driver assistance system and a driver assistance system for a motor vehicle. Finally, the invention relates to a motor vehicle comprising such a driver assistance system. Background technique [0002] Various methods are known from the prior art for maneuvering motor vehicles. For this purpose, for example...
