The invention discloses a low-floor tramcar and a constant deceleration brake control system and method thereof, vehicle load calculation is carried out by detecting a pressure value of a supporting oil cylinder through a pressure sensor, the vehicle load calculation only relates to a measurement value, and the measurement value is detected by a high-precision pressure sensor. Therefore, the accuracy of load measurement is greatly improved, the control accuracy of braking deceleration is improved, and the influence of the change of the elastic deformation coefficient of the rubber-metal pad on load measurement is avoided. And then the required hydraulic pressure is obtained according to the load value, the output hydraulic pressure is accurately controlled according to the required hydraulic pressure when the braking electromagnetic valve is powered on or powered off, constant deceleration braking control under different loads is achieved, and driving safety is guaranteed.
本发明公开了一种低地板有轨电车及其恒减速制动控制系统与方法,通过压力传感器检测支撑油缸压力值来进行车辆载荷计算,车辆载荷计算仅涉及到一个测量值,而该测量值又是采用高精度压力传感器检测,因此大大提高了载荷测量的精确度,从而提高了制动减速度的控制精度,避免了橡胶堆弹性变形系数变化对载荷测量的影响;再根据载荷值得到所需液压力,根据所需液压力在制动电磁阀有无电时实现对输出的液压力的精确控制,实现了不同载荷下恒减速制动控制,保证了行车安全。
