A method and system for assisting the driver of a motor vehicle in a lane-change manoeuvre

摘要

Described herein are a method and a system for assisting the driver of a motor vehicle (A) in a lane-change manoeuvre, by signalling the emergency condition generated by the approach of another vehicle (D) along the same lane onto which the first motor vehicle is moving. In the external rear-view mirror of the first motor vehicle (A) there is integrated a CMOS optoelectronic sensor, the output signals of which are processed for detecting the lateral distance between the motor vehicle (A) and the side (M) of the lane (L1) on which it is travelling. An alarm signal is generated in the case where there is simultaneously detected either a lateral approach of the first motor vehicle (A) to the side (M) of the lane (L1), or the approach of another motor vehicle (D) on the lane (L2) onto which the first motor vehicle (A) is moving. <IMAGE>
