Monitoring device to detect whether another vehicle intends to move into the same lane

摘要

A driver assistance device for a motor vehicle comprises an environmental sensor 12, 13, 14 for monitoring a monitoring space 7 located laterally to the motor vehicle for the presence of an object 3 and an analysis unit 10 which receives a detection signal of the environmental sensor 12, 13, 14 for estimating a possible endangerment of the motor vehicle 1 by an object 3 present in the monitoring space 7 and for delivering at least one result signal representative for the endangerment. The analysis unit 10 is configured to judge on the basis of the detection signal whether an object 3 present in the monitoring space 7 is approaching a lane 5 adjacent to the lane 4 travelled by the motor vehicle 1, and to signal the result of the judgment in the result signal. The result signal may activate an optic, acoustic or haptic signal generator. A method for assisting the driver of a motor vehicle and a computer program are also disclosed.
