The invention relates to a driveline of a vehicle. The driveline includes a set of motors having variable regenerative efficiency levels. The set of motors includes at least one motor. The electric machine enables a relationship between electrical energy and thermal energy generated by the electric machine during regeneration to be varied. The driveline further includes a cooling system such that the cooling system can remove heat generated by each motor of the set of motors. The driveline comprises a control system adapted to receive state information indicative of a current state of the driveline, and for at least one electric machine of the set of electric machines, the control system is adapted to: receive brake torque information indicative of a requested brake torque to be generated by the electric machine; in response to the braking torque information and the state information, determining a target relationship between electric energy generated by the motor and thermal energy; controlling the electric machine to obtain the requested braking torque and the determined target relation between the electric energy and the thermal energy; and controlling the cooling system in response to the determined target relationship between the electrical energy and the thermal energy of the electric machine.
