The invention provides a vehicle, a brake control method and device of the vehicle and a storage medium, the vehicle comprises a brake master cylinder, a pedal input hydraulic cylinder and a pedal counter-force simulator, a first electromagnetic valve is arranged between the brake master cylinder and the pedal input hydraulic cylinder, and a second electromagnetic valve is arranged between the pedal input hydraulic cylinder and the pedal counter-force simulator, the first electromagnetic valve is a normally-closed electromagnetic valve, the second electromagnetic valve is a normally-open electromagnetic valve, and the method comprises the steps that a brake master cylinder push rod action signal is obtained; judging whether the electric power-assisted transmission system fails or not according to the action signal of the push rod of the brake master cylinder; if the electric power-assisted transmission system fails, the vehicle is controlled to enter a redundant braking mode, and according to the redundant braking mode, a first electromagnetic valve is controlled to be connected, a second electromagnetic valve is controlled to be disconnected, and a pedal input hydraulic cylinder assists a braking main cylinder to build pressure and brake the vehicle. Therefore, when the electric power-assisted transmission system fails, the vehicle is controlled to enter the redundant braking mode, so that safe braking of the vehicle is ensured.
本发明提出了一种车辆及其制动控制方法、装置和存储介质,其中,车辆包括制动主缸、踏板输入液压缸和踏板反力模拟器,制动主缸与踏板输入液压缸之间设置有第一电磁阀,踏板输入液压缸与踏板反力模拟器之间设置有第二电磁阀,其中,第一电磁阀为常闭电磁阀,第二电磁阀为常开电磁阀,方法包括:获取制动主缸推杆动作信号;根据制动主缸推杆动作信号,判断电助力传动系统是否发生失效;若电助力传动系统发生失效,则控制车辆进入冗余制动模式,其中,冗余制动模式为控制第一电磁阀连接,并控制第二电磁阀断开,以通过踏板输入液压缸辅助制动主缸进行建压与车辆制动。由此,在电助力传动系统失效时,控制车辆进入冗余制动模式,以确保车辆安全制动。
