Embodiment Construction

[0024] It will now be assumed in the continuation of the description that the motor vehicle 1 is equipped with the driver assistance device according to the invention.

[0025] The surrounding detection sensors of the driver assistance device are arranged on both sides of the motor vehicle 1 , here for example on the exterior mirrors, for monitoring the monitoring spaces 7 on the left and right of the vehicle 1 . The boundaries of each monitoring space 7 can be defined, for example, by a spatial angle from which the sensor can receive radiation when the sensor for detection of the surroundings is a camera or a receiver of rays other than light, especially radio waves, from which the sensor can receive radiation, in the figure Each is delimited by a dash-dot line that follows one another at the position of the exterior mirror. Furthermore, the monitoring space can be limited to a defined distance from the vehicle 1 , for example on the basis of triangulation or time-of-flight m...

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.

Description

technical field [0001] The invention relates to a device and a method for assisting motor vehicle drivers when merging in multi-lane streets. Background technique [0002] For example by DE19921449C1 discloses such a car driver assistance device, it monitors whether there are other vehicles on the lane adjacent to the lane occupied by the car and will drive the car when changing to the adjacent lane will cause a collision with the vehicle already occupying the lane The officer issued a warning signal. [0003] The known driver assistance device monitors the so-called blind spot, that is, the area behind the side of the vehicle controlled by the driver assistance device, which is only difficult for the driver of the vehicle to see in the rearview mirror and is easily overlooked. Vehicles approaching from behind. [0004] Conventional driver assistance devices do not take into account a vehicle driving in the next lane parallel to the vehicle being operated by the driver ass...
