Device and method for driver assistance
First Claim
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.

Abstract
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.

11. A method for assisting a driver of a motor vehicle, the method comprising the steps of:
-
electronically monitoring a monitoring space located laterally of the motor vehicle for electromagnetic radiation indicating the presence of a second vehicle or an object; receiving a signal that is emitted by the second vehicle present in the monitoring space and that indicates an imminent or occurring lane change of the second vehicle; determining from the electromagnetic radiation whether the second vehicle present in the monitoring space is approaching a lane adjacent to a lane traveled by the motor vehicle; estimating a speed component of the motor vehicle transverse to a longitudinal direction; derive a curvature of one of the lane traveled by the motor vehicle and the lane adjacent thereto on a basis of map data and to rectify the speed component by a curvature-related fraction; and signaling results of the determination in a detection signal perceptible by the driver. - View Dependent Claims (12, 13)

14. A non-transitory computer readable medium embodying a computer program product, the computer program product comprising a driver assistance program configured to:
-
monitor a monitoring space located laterally of the motor vehicle for a presence of a second vehicle; receive a signal that is emitted by the second vehicle present in the monitoring space and that indicates an imminent or occurring lane change of the second vehicle; determine whether the second vehicle present in the monitoring space is approaching a lane adjacent to a lane traveled by the motor vehicle; and signal when the second vehicle is present in the monitoring space and is approaching the lane adjacent to the lane traveled by the motor vehicle with a detection signal if 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 a delimitation of the lane adjacent to a lane traveled by the motor vehicle. - View Dependent Claims (15)
