Driver assistance system for a motor vehicle

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...
