Abstract
The invention relates to a method for assisting a driver of a motor vehicle, in particular of an electric vehicle, during a driving process for overcoming an obstacle which is close to the ground and has a slow speed. In this context, the method has the following steps: transmission (S1) of a torque to the wheels which are to be driven in order to overcome the obstacle, detection (S6) that the obstacle has been overcome, and automatic reduction in the torque and/or automatic generation (S7) of a braking torque in order to decelerate the motor vehicle directly after the detection.
Claims11
A method for assisting a driver of a motor vehicle during a driving procedure to overcome an obstacle on a roadway at a first velocity, the method comprising:
- actuating an acceleration pedal;
- transmitting a drive torque to the wheels of the motor vehicle;
- analyzing, with a control unit, a recorded motor current of an electric motor configured to drive the motor vehicle;
- recognizing that the obstacle is present, when an acceleration pedal gradient associated with the acceleration pedal falls below a threshold value and when a buildup in the drive torque results in no acceleration of the motor vehicle in a first direction;
- and
- automatically decreasing the drive torque and producing a braking torque to decelerate the motor vehicle upon recognizing the obstacle has been overcome.
An electric vehicle configured to execute a method to overcome an obstacle at a first velocity, the method comprising:
- actuating an acceleration pedal;
- transmitting a drive torque to the wheels of the electric vehicle to overcome the obstacle;
- analyzing, with a control unit, a recorded motor current of an electric motor configured to drive the electric vehicle to overcome the obstacle;
- recognizing that the obstacle is present, when an acceleration pedal gradient associated with the acceleration pedal falls below a threshold value and when a buildup in the drive torque results in no acceleration of the motor vehicle in a first direction;
- and
- at least one selected from the group consisting of automatically decreasing the drive torque and automatically producing a braking torque to decelerate the electric vehicle immediately after the recognition that the obstacle has been overcome.
