Abstract:
1. A device for commanding braking in a motor vehicle having a member by which a driver actuates braking, the device comprising: a reaction device applying a reaction force; a first moving component driven by the member via which the driver actuates the braking; a second moving component having a brake boost actuator driving a force application element wherein the brake boost actuator axially moves the second moving component without moving the first moving component during rest and during braking; a sensor that senses a change of position of said second moving component relative to the first moving component; a processor configured to formulate control setpoints for commanding the brake boost actuator, in such a way as to generate a variable offset between the positions of said first and second moving components during a single braking stroke and to maintain said offset at a control setpoint both while braking and while at rest.
