The invention discloses a vehicle driving control method and system based on road surface recognition and available driving power, and belongs to the technical field of vehicle driving control. The method comprises the steps that the available driving power and driver demand torque are calculated by obtaining information such as the vehicle speed, the longitudinal acceleration, the gradient and the accelerator pedal opening degree of a target vehicle; evaluating the road adhesion coefficient and grade based on the vehicle speed, the longitudinal acceleration, the gradient and the motor driving torque; according to the road adhesion grade and the available driving power, the vehicle drivability grade is selected, and the rising and falling slope limit values of the torque are set, so that the torque required by a second driver is obtained; and the torque is transmitted to a motor controller to execute driving control. According to the method, by judging the driving road condition of the vehicle and calculating the available driving power, the acceleration performance of the vehicle is actively adjusted in advance, frequent slipping of the vehicle and triggering of the limited power are avoided, and the vehicle can have safer and better driving experience.

    本申请公开了一种基于路面识别和可用驱动功率的车辆驾驶控制方法及系统,属于车辆驾驶控制技术领域,该方法包括:通过获取目标车辆的车速、纵向加速度、坡度、油门踏板开度等信息,计算可用驱动功率和驾驶员需求扭矩;基于车速、纵向加速度、坡度及电机驱动扭矩评估路面附着系数和等级;根据路面附着等级和可用驱动功率,选择车辆驾驶性等级,并设定扭矩的上升和下降斜率限制值,从而得到第二驾驶员需求扭矩;将该扭矩传递给电机控制器执行驾驶控制。该方法通过判断车辆行驶路况和计算可用驱动功率,主动提前调整车辆加速性能,避免车辆频繁打滑和触发限功率,能够使车辆拥有更安全、更好的驾驶体验。
