A splitting of drive torque between front and rear wheelsets includes an actuator to split the torque between the wheelsets, an electronic unit controlling switching of the actuator into a coupled or uncoupled mode, a mechanism electrically powering the electronic unit, and sensors. The electronic unit can make the system adopt: an active operation in which a control signal is generated and the temperature of the actuator is estimated; and a sleep mode in which the temperature of the actuator is not estimated; the switch to sleep mode being authorized: only when the engine is stopped, and if the actuator temperature is below or equal to a threshold or a maximum time period has elapsed. |
