The invention relates to the technical field of vehicle control, in particular to a control method capable of avoiding vehicle anchoring caused by brake lamp switch damage. When a driver steps on a brake pedal and presses a PEPS button, if the whole vehicle controller only receives a PEPS button signal, the vehicle is only powered on; when the driver steps on the brake pedal again, the ESC controller sends a brake master cylinder signal to the whole vehicle controller or the IPB controller sends a push rod stroke signal to the whole vehicle controller; when the pressure of the brake master cylinder is larger than or equal to the pressure threshold value or the stroke of the push rod is larger than or equal to the stroke threshold value, the whole vehicle controller judges that a driver steps on a brake pedal, and the vehicle is started when a PEPS button is received. A logic control mode can be adopted to solve the problem that the brake lamp switch is damaged to cause the vehicle to break down, and when the brake lamp switch breaks down, a driver can still start and drive the vehicle so that the driver can go close to a maintenance point to maintain the vehicle.
本发明涉及车辆控制技术领域,具体涉及一种可避免制动灯开关损坏导致车辆抛锚的控制方法。驾驶员踩下制动踏板并按下PEPS按钮时,若整车控制器仅接收到PEPS按钮信号,则车辆仅上电;驾驶员再次踩下制动踏板时,ESC控制器向整车控制器发送制动主缸信号或IPB控制器向整车控制器发送推杆行程信号;当制动主缸压力大于等于压力阈值或推杆行程大于等于行程阈值,则整车控制器判断为驾驶员有踩制动踏板动作,并在接收到PEPS按钮时启动车辆。能采用逻辑控制的方式解决制动灯开关损坏导致车辆抛锚的问题,当制动灯开关故障时,驾驶员仍然可以启动及驾驶车辆,以便可以去临近维修点进行车辆维修。
