Method and device for estimating the residual torque between at least one braking element and one braked element of a vehicle brake

Abstract

The method for estimating the residual torque between at least one braking element (3, 3') and a braked element (2) of a brake (1) of a vehicle, in which the braking element (3, 3 ') includes at least one force sensor (6), comprises the steps of: - monitoring the activated / deactivated status of the brake (1); - temporal acquisition of a force signal generated by the force sensor (6); - calculation of the variation field (Cv, C'v) of the force signal; - calculation of a primary indicator (Ip) of residual torque in which the calculated value of said variation field (Cv, C'v) of the force signal is inputted into a primary calculation algorithm (Ap); wherein the primary indicator of residual torque (Ip) is calculated and the calculated value of said primary indicator of residual torque (Ip) is validated only if the temporal acquisition of the force signal occurred when the brake was in deactivated status.
