Abstract:
1. A method of managing parking braking in a braking system for a vehicle fitted with at least one electric brake including at least one electric actuator having a pusher actuated by an electric motor for selectively applying a force against friction elements of the brake, the method comprising executing on a controller the steps of: establishing a plurality of direct adjustment tables for parking braking, corresponding to braking situations at different energy levels; when applying parking braking, selecting a direct adjustment table corresponding to a braking situation preceding the application of parking braking; and directly adjusting a parking braking force in application with the selected direct adjustment table; wherein the method further comprises the steps of: selecting a first direct adjustment table and applying it for a predetermined initial application time; making a first adjustment; comparing a real change in position of the pusher with a theoretical change in position of the pusher obtained from the direct adjustment tables after an application time equal to the initial application time; and selecting a second direct adjustment table for which the theoretical change in position of the pusher is the closest to the real change in position, and wherein the plurality of direct adjustment tables is selected as a function of a braking history.
