Abstract
The disclosure relates to a method for actuating an electric drive of a trailer vehicle with a towing vehicle, including the steps: determining a current slip of at least one driven wheel of a towing vehicle pulling the trailer vehicle, determining an expected slip for the driven wheel of the towing vehicle, determining an acceleration demand depending on the determined current slip and the determined expected slip and actuating the electric drive depending on the acceleration demand. The disclosure also relates to a control unit for executing the method, a towing vehicle, a trailer vehicle and a vehicle combination.
Claims20
A method for actuating an electric drive of a trailer vehicle with a towing vehicle, the method comprising:
- determining a current slip of at least one driven wheel of the towing vehicle pulling the trailer vehicle;
- determining an expected slip for the at least one driven wheel of the towing vehicle;
- determining an acceleration demand in dependence upon the determined current slip and the determined expected slip;
- and,
- actuating the electric drive via an actuating signal in dependence upon the acceleration demand.
A control unit comprising:
- a processor;
- a computer readable storage medium having stored thereon program code for actuating an electric drive of a trailer vehicle with a towing vehicle;
- said program code being configured, when executed by said processor, to:
- determine a current slip of at least one driven wheel of the towing vehicle pulling the trailer vehicle;
- determine an expected slip for the at least one driven wheel of the towing vehicle;
- determine an acceleration demand in dependence upon the determined current slip and the determined expected slip;
- and,
- actuate the electric drive via an actuating signal in dependence upon the acceleration demand.
