The invention provides a vehicle braking method, a vehicle braking system, a vehicle and a vehicle braking device. The vehicle braking method comprises the steps that under the condition that it is determined that a vehicle braking signal is received, the IBC state is detected; when it is determined that the IBC state is the failure state, a control instruction set is generated, the control instruction set is used for controlling four driving motors of the vehicle to output preset braking torque so as to brake the vehicle, the driving motors and four wheels of the vehicle are arranged in a one-to-one correspondence mode, and the four driving motors are independently controlled. According to the technical scheme, compared with a traditional non-four-motor mechanism type, the motor braking ratio is higher than hydraulic braking, the braking distance can be shorter, the driving endurance mileage is longer, four-motor braking control serves as the redundant braking scheme of vehicle braking, the whole vehicle can be braked under the condition that IBC failure of the vehicle is guaranteed, and meanwhile the braking speed is increased.
本发明提供了一种车辆制动方法、车辆制动系统、车辆、车辆制动装置。车辆制动方法包括:在确定接收到车辆制动信号的情况下,检测IBC状态;在确定IBC状态为失效状态的情况下,生成控制指令集,控制指令集用于控制车辆的四个驱动电机输出预设制动扭矩,以制动车辆,其中,驱动电机与车辆的四个车轮一一对应设置,四个驱动电机之间相互独立地控制。应用本发明的技术方案,相比于传统的非四电机构型,电机制动比比液压制动更快,可以使得制动距离更短、行驶续航里程更长,四电机制动控制作为车辆制动的冗余制动方案,可以在确保车辆的IBC失效的情况下整车制动,同时提升制动速度。
