Abstract: The disclosure relates to a vehicle control unit (VCU), wherein a hill hold feature enables keeping a position of a vehicle at standstill on a slope with the aid of an electric drive of the vehicle. The VCU is configured to receive information for determining a hold torque of the electric drive for holding the vehicle at standstill on the slope, information about a cooling of the electric drive and information about an initial temperature of the electric drive when the hill hold feature is enabled. The VCU is configured to determine a time until a derating of the electric drive begins based on a predefined derating model and the above information. The VCU is configured to determine a time indicator indicating the remaining time for which the hill hold feature can be provided based on the time until derating of the electric drive begins.
