Turn Assistant in a Vehicle

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.

11. 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 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.

13. The method according to claim 11, wherein the creation of the prospective driving trajectory takes dimensions of the motor vehicle into account.

14. The method according to claim 11, wherein the creation of the prospective driving trajectory takes a prospective steering behavior of a driver into account.

15. The method according to claim 11, wherein the creation of the environment model is undertaken by way of optical sensors.

16. The method according to claim 11, wherein the creation of the environment model includes an identification of moving obstacles whose trajectory of motion is taken into account.

17. The method according to claim 11, wherein the output of the warning function includes an output of a visual warning, a vibration, and/or an acoustic warning.

18. The method according to claim 11, wherein the output of the warning function includes an active intervention in a longitudinal guidance and/or a lateral guidance of the vehicle.

19. 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 in the turning direction; 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.

20. 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 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.

DETAILED DESCRIPTION OF THE DRAWING

[0038] FIG. 1 shows, in a schematic flowchart, a method for driver assistance for the purpose of avoiding a collision of a bodywork side on the inside of a curve, or of a rear wheel on the inside of a curve, with obstacles in a direction of turn of a motor vehicle, featuring creation 100 of an environment model that specifies the immediate environment of the vehicle together with potential obstacles in the direction of turn, wherein the following are provided: measurement 101 of a steering-angle of the motor vehicle; creation 102 of a prospective driving trajectory of the motor vehicle as a function of the measured steering-angle; and output 103 of a warning function if the prospective driving trajectory comes into contact with at least one obstacle. The warning function may also include an intervention in the longitudinal and/or lateral guidance.

[0039] In this connection, a person skilled in the art will recognize that the steps may feature further sub-steps, and, in particular, that the steps of the method may each be executed iteratively and/or in a different order. The creation of the environment model may be undertaken iteratively and dynamically in such a manner that a current environment model is built up successively. In this way, the vehicle can approach a point and register it, already during the journey, by means of optical sensors. The creation of the prospective trajectory is also undertaken repeatedly in such a manner that a current trajectory is always available. The output of the warning function may occur until such time as the hazardous situation has been resolved. The warning function may also include an intervention in the longitudinal and/or lateral guidance.

[0040] Not shown in the present case is a data memory or a computer-readable medium with a computer-program product featuring control commands that implement the proposed method or operate the proposed system arrangement when they are caused to be executed in a computer.
