The invention discloses an electronic hand brake control system and method, and relates to the technical field of automobile brake control, the control system comprises a vehicle control unit, an electronic hand brake switch, a sensor and a plurality of contact switches, the vehicle control unit is connected with the sensor and the electronic hand brake switch, and is also connected with the plurality of contact switches and the electronic hand brake switch; and the controller is configured to judge whether the plurality of contact switches and the sensor are normal or not according to the working states of the plurality of contact switches and the current voltage value of the sensor, and control the brake according to the judgment result and the voltage value of the sensor or the working states of the plurality of contact switches or the braking force determined by the current vehicle speed and gradient. According to the electronic hand brake control system disclosed by the embodiment of the invention, when the output voltage of the sensor has an error and the opening stroke of the electronic hand brake switch has an error, the brake is controlled through the plurality of contact switches, so that the reliability of the electronic hand brake switch is ensured, the braking force can be adjusted, and the safety coefficient is improved.
本发明公开了一种电子手刹控制系统及方法,涉及汽车制动控制技术领域,所述控制系统的包括整车控制器、电子手刹开关、传感器、多个触点开关,整车控制器与传感器和电子手刹开关连接,还与多个触点开关和电子手刹开关连接,且被配置为根据多个触点开关的工作状态及传感器的当前电压值分别判断多个触点开关及传感器是否正常,根据判断结果及传感器的电压值或多个触点开关的工作状态或当前车速和坡度确定的制动力大小控制刹车制动。本发明实施例电子手刹控制系统在传感器输出电压存在误差导致电子手刹开关的开度行程产生误差时,通过多个触点开关控制刹车制动,保证了电子手刹开关的可靠性,使制动力大小可以调节,提高了安全系数。
