The invention relates to the technical field of new energy vehicles, and discloses a vehicle emergency braking method which comprises the following specific steps: when vehicle braking fails, a wheel speed sensor detects the rotating speed of a brake hub and sends a signal to an electronic control unit, and meanwhile, a variable resistance sensor detects the stroke of a brake pedal and sends the stroke to the electronic control unit; the electronic control unit compares the instant signals transmitted by the wheel speed sensor and the variable resistance sensor with standard data of the data storage unit, if the data comparison reference values are the same, braking is normal, operation is not carried out, and if the data comparison reference values are different, braking is abnormal. If yes, the brake unit is controlled to start through the electronic brake unit. Through mutual cooperation of the electronic control unit and the rotating speed detection unit, once the vehicle fails to brake, manual operation is not needed, the vehicle is automatically braked through the electronic control technology, and safety and reliability are achieved.

    本申请涉及新能源汽车技术领域,公开了一种车辆紧急制动方法,包括具体方法步骤如下:当车辆制动失灵后,轮速传感器检测出制动轮毂的转速,并发出信号给予电子控制单元,同时可变电阻传感器检测出制动踏板的行程,并发出信号给电子控制单元,电子控制单元把轮速传感器和可变电阻传感器传过来即时信号与数据存储单元的标准数据进行对比,若数据对比参照值相同,即证明制动正常,不进行操作,若数据对比参照值不同时,即说明制动异常,则通过电子制动单元控制制动单元启动。通过电子控制单元、转速检测单元相互配合,车辆一旦遇到车辆制动失灵的时候,不需要人为地操作,而是通过电子控制技术,自动产生对车辆进行制动作用,安全可靠。
