More Information
Summary:A control unit for a heavy duty vehicle. The vehicle includes an electric machine connected to first and second driven wheels via an differential. The control unit includes a first wheel slip control module associated with the first driven wheel, and a second wheel slip control module associated with the second driven wheel, where each wheel slip control module is arranged to determine an obtainable torque by the respective wheel based on a current wheel state, wherein the control unit is arranged to determine a required torque to satisfy a requested acceleration profile by the vehicle, and to request a torque from the electrical machine corresponding to the smallest torque out of the obtainable torques for each driven wheel and the required torque.
