A brake system (4) for a vehicle (8) comprises: at least one disc brake (12) comprising a brake disc (16) having a disc brake caliper (20) and at least one pair of pads (24) on opposite sides of each other in an actuation axial direction (A-A); at least one electric actuator (32) operatively connected to a piston (36) acting as a pusher on at least one of the pads (24); a processing and control unit (40) operatively connected to said electric actuator (32) and programmed such that, during a brake request, the pistons (36) and the respective pads (24) are moved to a forward position in an actuation axial direction (A-A) to press the pads (24) into contact with the brake disc (16); and bringing the piston (36) and its pad into a rest or rear position in which there is determined a gap (44) between the pad (24) and the brake disc (16), in which the processing and control unit (40) is programmed to implement an algorithm that: in the absence of a brake request, the pad (24) and the brake disc (16) are separated from each other by the processing and control unit (40); the algorithm operates the electric actuator (32) by varying the gap (44) according to at least one dynamic parameter of the vehicle (8) defining a prediction of a future braking action request.
一种用于车辆(8)的制动系统(4)包括:至少一个盘式制动器(12),该盘式制动器包括制动器盘(16),该盘式制动器具有盘式制动器卡钳(20),以及位于沿致动轴向方向(A‑A)的彼此相反的两侧上的至少一对衬垫(24);至少一个电动致动器(32),该电动致动器操作性地连接至活塞(36),该活塞作为推动器作用在所述衬垫(24)中的至少一个衬垫上;处理及控制单元(40),该处理及控制单元操作性地连接至所述电动致动器(32)并且被编程为使得:在制动请求期间,使活塞(36)和相应的衬垫(24)沿致动轴向方向(A‑A)移动至前部位置,以将衬垫(24)按压成与制动器盘(16)接触;以及使活塞(36)及其衬垫进入静置或后部位置,在该静置或后部位置中,衬垫(24)与制动器盘(16)之间确定有间隙(44),其中,处理与控制单元(40)被编程为实现下述算法:在没有制动请求的情况下,该算法通过根据车辆(8)的对未来制动作用请求的预测进行限定的至少一个动态参数来改变所述间隙(44)而使电动致动器(32)进行操作。
Disc brake equipped with dynamic adjustment of gap between brake disc and pad and associated method
