Reversing assistant
First Claim
1. A system in a vehicle for assisting a driver of a vehicle when reversing, comprising:
- at least one sensor unit which detects objects within surroundings to a rear of the vehicle;
a computing unit which is connected to the sensor unit and processes the detected objects; and
an actuator unit which is connected to the computing unit, wherein the computing unit generates a virtual driving tube within which the vehicle can move backward without colliding with the detected objects, and the actuator unit is a steering actuator which is actuated by the computing unit and outputs haptic information which informs the driver of the vehicle about a steering direction, which is to be adopted next for reverse travel within the driving tube;
wherein the steering actuator provides the haptic information to a steering wheel as a force in the steering direction to be adopted when the vehicle will remain within the virtual driving tube if the steering direction is adopted; and
wherein the steering actuator provides the haptic information to the steering wheel as a force in an opposite direction to the steering direction to be adopted when there is a risk that the vehicle will leave the virtual driving tube if the steering direction is adopted.

Abstract
The invention relates to a system in a vehicle for assisting a driver of a vehicle when reversing, having at least one sensor unit which detects objects within the surroundings to the rear of the vehicle, having a computing unit which is connected to the sensor unit and has the purpose of processing the detected objects, and having an actuator unit which is connected to the computing unit. According to the invention, the computing unit generates a virtual driving tube within which the vehicle can move backward without colliding with the detected objects. The actuator unit is a steering actuator which is actuated by the computing unit and has the purpose of outputting haptic information which informs the driver of the vehicle about the steering direction, which is to be adopted next for reverse travel within the driving tube.
