Abstract:
1. A driver assistance system for a motor vehicle, comprising: a speed detector for detecting a speed of the motor vehicle; a preceding vehicle detector having at least one video camera and at least one distance sensor for detecting a distance between the motor vehicle and a preceding vehicle driving in front of the motor vehicle, the distance forming a part of preceding vehicle driving data; a preceding vehicle speed determination device for determining a preceding vehicle speed of the preceding vehicle forming a part of the preceding vehicle driving data; and an electronic actuation unit configured to: (i) trigger autonomous braking of the motor vehicle when predetermined brake trigger driving data are present, (ii) terminate autonomous braking of the motor vehicle when predetermined brake abort driving data are present, and (iii) effect; (a) redundant detection of the preceding vehicle driving data, (b) non-redundant detection of the preceding vehicle driving data when redundant detection of the preceding vehicle driving data is not possible, (iii) a comparison of the non-redundantly detected preceding vehicle driving data with preceding vehicle driving data detected redundantly within a predefined time, and (iv) when the non-redundantly detected preceding vehicle driving data correspond to the redundantly detected preceding vehicle driving data, use of the non-redundantly detected preceding vehicle driving data to determine whether the predetermined brake trigger driving data or the predetermined brake abort driving data are present.
