Device and method for driver assistance

摘要

A driver assistance device for a motor vehicle is provided. The driver assistance device includes an environmental sensor configured for monitoring a monitoring space located laterally to the motor vehicle for the presence of an object. An analysis unit is configured to receive a detection signal from the environmental sensor for estimating a possible endangerment of the motor vehicle by the object present in the monitoring space and to deliver a result signal representative of the endangerment. The analysis unit is configured to judge on the basis of the detection signal whether the object present in the monitoring space is approaching a lane adjacent to a lane traveled by the motor vehicle and to signal a result of a judgment in the result signal.

1. A driver assistance device for a motor vehicle, the driver assistance device comprising:
an environmental sensor configured to monitor a monitoring space located laterally to the motor vehicle for the presence of a second vehicle and is further configured to detect a delimitation of the lane adjacent to the lane traveled by the motor vehicle, wherein the environmental sensor comprises a receiver configured to receive a signal emitted by the second vehicle; and an analysis unit configured to receive a detection signal from the environmental sensor, wherein based on the detection signal the analysis unit is further configured to determine whether the second vehicle present in the monitoring space is approaching a lane adjacent to a lane traveled by the motor vehicle, and to generate a signal based thereon indicating when a distance of the motor vehicle from the second vehicle measured transversely to a longitudinal direction of the motor vehicle decreases more rapidly than a distance of the motor vehicle from the delimitation.
