The invention provides an off-road cruise control method based on dual-motor PI control, which comprises the following steps: S1, when a vehicle control unit recognizes that a vehicle enters an off-road cruise mode, recognizing a current target gear; s2, the vehicle control unit calculates the target vehicle speed according to the target gear; s3, the vehicle control unit calculates the difference value between the target vehicle speed and the actual vehicle speed, and an initial target torque is calculated according to the difference value through a PI control algorithm; and S4, the vehicle control unit judges whether the initial target torque is distributed to a front motor and a rear motor of the vehicle or not according to the state of the vehicle. According to the invention, the vehicle speed of the vehicle during cross-country cruise can be controlled in real time, so that the vehicle speed is relatively stable.

    本发明提供了一种基于双电机PI控制的越野巡航控制方法,其包括以下步骤:步骤S1、整车控制器识别到车辆进入越野巡航模式时,对当前的目标档位进行识别;步骤S2、整车控制器根据目标档位计算出目标车速;步骤S3、整车控制器计算目标车速和实际车速的差值,并根据该差值利用PI控制算法计算出初始目标扭矩;步骤S4、整车控制器根据整车状态,判断是否将初始目标扭矩分配给车辆的前电机和后电机。本发明能够对车辆在越野巡航时的车速进行实时控制,使得车速较为稳定。
