The invention relates to the field of vehicle driving control, and provides a driving control method and system for a hybrid vehicle. The hybrid vehicle comprises a front axle power system provided with an engine and a rear axle power system provided with a driving motor and an absolute position sensor. The method comprises the following steps: acquiring a current pulse width modulation signal which is from and measured by an absolute position sensor and shows the current position of a shifting fork in real time; and determining the current position of the shifting fork according to the current pulse width modulation signal obtained in real time, and controlling the shifting fork to move to a position according to the current position, so that the output gear of the driving motor can be a neutral gear, and when the driving motor is in the neutral gear, the hybrid vehicle is driven by the engine of the front axle power system to limp. According to the driving control method for the hybrid vehicle, the vehicle is controlled to continue running when the rear axle power system breaks down, and the usability of the vehicle is improved.

    本发明涉及车辆驱动控制领域,提供一种混动车辆的驱动控制方法、系统,混动车辆包括配置有发动机的前桥动力系统和配置有驱动电机以及绝对位置传感器的后桥动力系统,包括:实时获取来自绝对位置传感器的其所测得的示出拨叉的当前位置的当前脉宽调制信号;以及根据实时获取到的当前脉宽调制信号,确定拨叉的当前位置,并根据当前位置,控制拨叉移动至一位置以使得驱动电机的输出挡位为空挡,其中驱动电机处于空挡时,混动车辆在前桥动力系统的发动机的驱动下跛行。本发明的混动车辆的驱动控制方法在后桥动力系统出现故障时控制车辆继续行驶,增加了车辆的可用性。
