Abstract

A method is provided for driver assistance in order to avoid a collision of a bodywork side on an inside of a curve, or of a rear wheel on the inside of the curve, with an obstacle in a turning direction of a motor vehicle. The method creates an environment model that specifies an immediate environment of the motor vehicle together with potential obstacles in the turning direction; measures a steering-angle of the motor vehicle; creates a prospective driving trajectory of the motor vehicle as a function of the measured steering-angle; and outputs a warning function when the prospective driving trajectory indicates a probable contact of the motor vehicle with at least one obstacle.

First claim

What is claimed is:

1 . A method for driver assistance in order to avoid a collision of a bodywork side on an inside of a curve, or of a rear wheel on the inside of the curve, with an obstacle in a turning direction of a motor vehicle, the method comprising:
creating an environment model that specifies an immediate environment of the motor vehicle together with potential obstacles only in the turning direction; measuring a steering-angle of the motor vehicle; creating a prospective driving trajectory of the motor vehicle as a function of the measured steering-angle; and outputting a warning function when the prospective driving trajectory indicates a probable contact of the motor vehicle with at least one obstacle.

2 . The method according to claim 1 , wherein
the creation of the prospective driving trajectory is undertaken on the basis of a vehicle model.

3 . The method according to claim 1 , wherein
the creation of the prospective driving trajectory takes dimensions of the motor vehicle into account.

4 . The method according to claim 1 , wherein
the creation of the prospective driving trajectory takes a prospective steering behavior of a driver into account.

5 . The method according to claim 1 , wherein
the creation of the environment model is undertaken by way of optical sensors.

6 . The method according to claim 1 , wherein
the creation of the environment model includes an identification of moving obstacles whose trajectory of motion is taken into account.

7 . The method according to claim 1 , wherein
the output of the warning function includes an output of a visual warning, a vibration, and/or an acoustic warning.

8 . The method according to claim 1 , wherein
the output of the warning function includes an active intervention in a longitudinal guidance and/or a lateral guidance of the vehicle.

9 . A system arrangement for driver assistance in order to avoiding a collision of a bodywork side on an inside of a curve, or of a rear wheel on the inside of the curve, with an obstacle in a turning direction of a motor vehicle, comprising:
at least one sensor configured to create an environment model that specifies an immediate environment of the motor vehicle together with potential obstacles only in the turning direction; a computer comprising:
a measuring unit configured to measure a steering-angle of the motor vehicle;
an arithmetic logic unit configured to create a prospective driving trajectory of the motor vehicle as a function of the measured steering-angle; and
an interface configured to output a warning function when the prospective driving trajectory indicates probable contact of the motor vehicle with at least one obstacle.

10 . A computer product comprising a non-transitory computer-readable medium having stored thereon program code which, when executed on a processor, carries out the acts of:
creating an environment model that specifies an immediate environment of the motor vehicle together with potential obstacles only in the turning direction; measuring a steering-angle of the motor vehicle; creating a prospective driving trajectory of the motor vehicle as a function of the measured steering-angle; and outputting a warning function when the prospective driving trajectory indicates a probable contact of the motor vehicle with at least one obstacle.
