Abstract
Apparatus, system and method for assisting a motor vehicle in assisted cornering. In order to carry out the cornering, two different assistance modes are provided in the driver assistance system, and from each of these modes different potential cornering speeds for driving through the corner are provided. A selection routine is configured in order to prioritize one of the two potential cornering speeds as a target speed for driving through the corner. According to the selection routine, a set driving mode can be taken into account, for example. Additionally or alternatively, a tiredness level of the driver can be incorporated into the selection.
Claims20
A method for assisting cornering of a motor vehicle using a driver assistance system, comprising:
- configuring a first assistance mode for the driver assistance system to perform assisted lateral guidance and longitudinal guidance of the motor vehicle;
- configuring a second assistance mode for the driver assistance system to perform longitudinal guidance of the motor vehicle;
- comparing, based on sensor data comprising a curve data record and a specified lateral acceleration limit for the motor vehicle, (i) a first potential cornering speed under the first assistance mode for driving through a curve, wherein the first potential cornering speed comprises a permitted cornering speed determined based on the specified lateral acceleration limit and the curve data record, and (ii) a second potential cornering speed under the second assistance mode for driving through the curve, wherein the second potential cornering speed is determined independent of the specified lateral acceleration limit for longitudinal guidance of the motor vehicle;
- and
- selecting one of the first or second potential cornering speeds as a target speed setpoint for driving through the curve using a specified selection routine, wherein the target speed setpoint is configured to be applied by the driver assistance system to control the steering system and/or the cruise control system during cornering, if the comparing determines that the first potential cornering speed is less than the second potential cornering speed.
