Problems solved by technology
[0003] A disadvantage of known driver assistance systems is that the autonomous braking is interrupted when the vehicle in front is no longer detected by the vehicle in front
It has been shown that such driver assistance systems often end autonomous braking prematurely, thereby increasing the risk of a collision and the potential intensity of an accident

Embodiment Construction
[0029] figure 1 A motor vehicle 10 is shown, which has a front side 12 on which a front vehicle detection device 14 is arranged. The preceding vehicle detection device 14 is designed for detecting a preceding vehicle 16 and has a first component in the form of a camera 18 with field of view G and a second component in the form of a distance sensor 20 . Distance sensor 20 is designed to measure distance A from front 12 of motor vehicle 10 to the rear of vehicle 16 in front.
[0030] Furthermore, motor vehicle 10 has a driving speed detection device 22 in the form of a speedometer, a yaw rate sensor 24 and a deceleration sensor 26 . The preceding vehicle-detection device 14 , the travel speed detection device 22 , the yaw rate sensor 24 , and the deceleration sensor 26 are travel data-sensors that detect travel data of the automobile 10 . These devices are all connected to the electrical control unit 28 by means of cables. The electronic control unit 28 includes a digital mem...

The invention relates to a driver assistance system for a motor vehicle, comprising a speed detection device (22) for detecting driving data in the form of a speed (vK) of the motor vehicle (10), a preceding vehicle detection device (14), which comprises as a first component at least one video camera (18) and as a second component at least one distance sensor (20), for detecting driving data in the form of a distance (A) from a preceding vehicle (16) driving in front of the motor vehicle (10), a preceding vehicle speed determination device for determining driving data in the form of a preceding vehicle speed (vVf) of the preceding vehicle (16), and an electric control unit (28), which is equipped to trigger an autonomous deceleration of the motor vehicle (10) with the presence of predetermined brake trigger driving data and to terminate the autonomous deceleration of the motor vehicle (10) with the presence of predetermined brake abortion driving data. According to the invention, the electric control unit (28) is equipped to carry out a method comprising the following steps: redundant detection of preceding vehicle driving data (A, vVf) of the preceding vehicle (15), and non-redundant detection of the preceding vehicle driving data (A, vVf) if a redundant detection of the preceding vehicle driving data (A, vVf) is not possible, comparing the non-redundantly detected preceding vehicle driving data to preceding vehicle driving data redundantly detected within a predetermined time (t), and using the non-redundantly detected preceding vehicle driving data in order to carry out step (d) if the non-redundantly detected preceding vehicle driving data correspond to the redundantly detected preceding vehicle driving data.
Description
technical field [0001] The invention relates to a driver assistance system for a motor vehicle, comprising: (a) a driving speed detection device for detecting driving data in the form of the driving speed of the motor vehicle; (b) a preceding vehicle detection device having at least A camera as the first part, and having at least one distance sensor as the second part, is used to detect the travel data in the form of the distance from the preceding vehicle traveling in front of the automobile; (c) the preceding vehicle speed-acquiring device, For knowing the speed of the preceding vehicle; and (d) an electric control unit configured to trigger autonomous braking of the vehicle when there is predetermined braking trigger-travel data, and when there is predetermined Braking Interrupt - Ends the car's autonomous braking when driving data. Background technique [0002] Driver assistance systems of this type are known and are used to reduce the severity of an accident or to comp...
