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.
Claims10
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.
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.
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.
