Title
(EN) METHOD FOR CONTROLLING A BRAKING SYSTEM OF A VEHICLE AND SYSTEM THEREOF
(FR) PROCÉDÉ DE COMMANDE D'UN SYSTÈME DE FREINAGE D'UN VÉHICULE ET SYSTÈME CORRESPONDANT
Abstract
(EN)
A method (500) for controlling a braking system of a vehicle, comprising steps of: receiving (501 ), by a vehicle control module, a braking request; receiving (502), by the vehicle control module, first input information representative of the vehicle; determining (503), by the vehicle control module, first intermediate information on the basis of said first input information; determining (504), by the vehicle control module, a reference force value on the basis of the first input information and of the braking request; detecting (505), by a first plurality of the detecting devices operatively associated with a corner of a vehicle, second input information representative of the braking system at the corner of the vehicle; determining (506), by a force estimation and validation module, an estimated force value on the basis of said first intermediate information and said second input information; determining (507), by the force estimation and validation module, a control quantity; determining (508), by a braking control module, a control signal of an electro-mechanical actuator of a brake caliper of the braking system on the basis of the control quantity and of the reference force value; providing (509), by the control module braking, said control signal to said electro-mechanical actuator.
