Abstract: A method controls a shift actuator with a sliding gear for a gearbox. The gearbox includes a control element for controlling a shift fork responsible for disengaging and engaging pinions on a shaft of the gearbox that receives torque from a traction machine powered by the on-board electrical system of the vehicle. The control element is positioned upstream of a mechanical spring-assist system and regulated in position by a DC actuating motor. The method includes temporarily raising a supply voltage applied to the actuating motor above a base voltage of an on-board electrical system during the disengaging and engaging the pinions.
