Embodiment Construction

[0016] figure 1 A motor vehicle 10 is shown which, during operation, travels in a direction of travel F on a roadway 12 . The lane 12 has a lane marking 14 on the left in the direction of travel and a lane boundary marking 16 on the right in the direction of travel. Located on the front side 18 of the motor vehicle 10 is a travel data sensor 20 in the form of a radar rangefinder, which detects the distance A to a preceding vehicle 22 at intervals of, for example, less than one second, ie quasi-continuously.

[0017] Motor vehicle 10 has a lane keeping camera 24 on front side 18 , the lane keeping camera field of view G of lane keeping camera 24 is set in such a way that lane markings 14 and lane boundary markings 16 can be detected. The images captured by the lane keeping camera 24 are transmitted to an electrical control unit 26 which is also in communication with a travel data sensor 20 . The electric control device 26 continuously learns from the driving data of the drivi...

Abstract

The invention relates to a driver assistance system for a motor vehicle (10), comprising at least one driving data sensor (20) for sensing driving data that characterizes the driving condition of the motor vehicle (10), and an electrical controller (26) which is designed to initiate autonomous emergency braking of the motor vehicle (10) when predetermined driving data has been sensed. According to the invention, a device is provided which is designed to detect a preceding vehicle (22) located in front of the motor vehicle (10) in the direction of travel of the motor vehicle (10). The electrical controller (26) is designed to maintain a brake of the motor vehicle (10) in a braking position or bring the brake into the braking position following an emergency braking action when the device detecting a preceding vehicle detects the preceding vehicle (22).

Description

technical field [0001] The invention relates to a driver assistance system for a motor vehicle, comprising: at least one driving data sensor for detecting driving data representing the driving state of the motor vehicle; Trigger the car's autonomous emergency braking. According to a second aspect, the invention relates to a method for operating a motor vehicle. Background technique [0002] Driver assistance systems that trigger autonomous emergency braking in the presence of predetermined driving data are known, for example, under the name Brake Assistant or ACC (Adaptive Cruise Control). This driver assistance system detects multiple driving data of the car and combines them with algorithms to determine whether there is a situation with a high probability that the driver of the car has to brake because he brakes too slowly or not at all And an accident is about to happen. As soon as the car comes to a standstill, the known driver assistance systems end their interventio...
