The invention provides a brake-by-wire module, a brake-by-wire system and a control method for the brake-by-wire system. A control method for a brake-by-wire system comprises the steps that S2, when it is estimated that the current forward stroke of a main piston cannot meet a brake request, the following steps are executed: S31, the current forward stroke is executed till the stroke of the main piston reaches a first threshold value, and communication between a main brake cylinder and all sub brake cylinders is cut off; s32, the main piston retreats until the main brake cylinder is communicated with a liquid storage device, so that the brake liquid in the liquid storage device is supplemented into the main brake cylinder; s33, enabling the main piston to advance again, and enabling the main brake cylinder to be communicated with the sub brake cylinders again so as to further increase the brake fluid pressure in the sub brake cylinders; and S34, returning to the step S2. According to the device and the method, extreme braking working conditions are handled through control logic, so that the brake-by-wire module can be more compact.

    本发明提供了一种线控制动模块、线控制动系统和用于其的控制方法。一种用于线控制动系统的控制方法,包括:S2.在估测主活塞的当前前进行程无法满足制动请求时执行如下步骤:S31.执行当前前进行程直到所述主活塞行程达到第一阈值时,切断所述主制动缸与各个所述子制动缸的连通;S32.使所述主活塞后退直到所述主制动缸与储液器连通,以使得所述储液器中的制动液补充入所述主制动缸;S33.使所述主活塞再次前进,并且使所述主制动缸与各个所述子制动缸重新连通,以进一步增加各个所述子制动缸中的制动液压力;以及S34.返回所述步骤S2。根据本发明的装置和方法通过控制逻辑来应对极端制动工况,使得线控制动模块本身可更为紧凑。
