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.

A method for controlling a shift actuator with a sliding gear for a gearbox of a vehicle, the gearbox comprising 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 an on-board electrical system of the vehicle, the on-board electrical system including a low voltage battery, a high voltage battery, and a DC/DC converter, the control element being positioned upstream of a mechanical spring-assist system and regulated in position by a DC actuating motor, the method comprising:
- providing a supply voltage to the actuating motor that is equal to a base voltage of the lower voltage battery;
- and
- temporarily raising the supply voltage applied to the actuating motor above the base voltage during the disengaging and engaging the pinions.
