The invention relates to the field of hybrid power heavy commercial vehicle automatic mechanical gearbox control, and provides a hybrid power heavy commercial vehicle starting control method, which comprises the following steps: acquiring vehicle related signals, calculating the acquired signals to obtain starting resistance and torque, distributing the torque for the current vehicle mode, and controlling the starting speed of the hybrid power heavy commercial vehicle. According to the control method, the condition of the whole vehicle after starting is judged, the torque is controlled through an actuator by adopting a fuzzy PID algorithm, coordination among a clutch, an engine and a motor is guaranteed, the hybrid power heavy commercial vehicle can be smoothly started on the ramp road surface, and the problems of starting performance and ramp slip prevention of the hybrid power heavy commercial vehicle on the ramp road surface are effectively solved.
本发明涉及混合动力重型商用车自动机械变速箱控制领域,提供了一种混合动力重型商用车起步控制方法,通过采集车辆相关信号并将所采集的信号通过计算得到起步阻力以及扭矩,通过对当前车辆模式分别对扭矩进行分配,并判断整车的起步后的情况,通过执行器采用模糊PID算法控制扭矩,保证离合器、发动机、电机三者之间的协调,可使混合动力重型商用车实现坡道路面的顺利起步,有效的解决了混合动力重型商用车在坡道路况下的起步性能及坡道防溜问题。
