The invention discloses an intelligent passenger car road condition automatic identification control method and system, and the method comprises the steps: a main controller carries out the initial road condition identification judgment based on a vehicle environment image digital quantity and an obstacle distance digital quantity, and judges a current first road condition; the auxiliary controller performs secondary road condition recognition judgment based on the vehicle environment image digital quantity and the obstacle distance digital quantity, and judges a current second road condition; judging whether the second road condition is consistent with the first road condition or not, if yes, determining the current road condition, and if not, obtaining data again for judgment; whether steering is needed or not is judged based on the current road condition and the obstacle distance digital quantity, if yes, the offset is calculated, the steering angle of the whole vehicle is adjusted based on the offset, and if not, steering is not conducted, and the vehicle runs linearly at a constant speed; and judging whether the vehicle speed needs to be adjusted based on the current road condition and the current vehicle speed digital quantity, if so, adjusting the rotating speed of the motor, and if not, not adjusting. The road condition automatic identification control of whole vehicle driving is realized, and unpredictable errors caused by insufficient concentration of a driver are avoided.

    本发明公开一种智能客车路况自动识别控制方法及系统,主控制器基于车辆环境图像数字量和障碍物距离数字量进行初次路况识别判断,判断当前第一路况;辅助控制器基于车辆环境图像数字量和障碍物距离数字量进行二次路况识别判断,判断当前第二路况;判断第二路况与第一路况是否一致,若是则确定当前路况,若否则重新获取数据进行判断;基于当前路况与障碍物距离数字量判断是否需要转向,若是则计算偏移量,基于偏移量调整整车方向转角,若否则不进行转向,车辆匀速直线行驶;基于当前路况与当前车速数字量判断是否需要调整车速,若是则调整电机转速,若否不进行调整。实现整车驾驶的路况自动识别控制,避免驾驶员因专注度不足产生不可预知的失误。
