The invention discloses a vehicle driving control system, a control method thereof and a vehicle. The vehicle driving control system is characterized by comprising a vehicle body electronic stabilizing system and a whole vehicle controller, wherein the vehicle body electronic stabilizing system is used for detecting action of an accelerator pedal and action of a brake pedal of the vehicle, when the accelerator pedal and the brake pedal are not stepped down, the vehicle body electronic stabilizing system judges whether the vehicle is driven in a crawling manner or not according to wheel speed signals, and when the vehicle body electronic stabilizing system judges that the vehicle is driven in the crawling manner, the whole vehicle controller is used for outputting an accelerator opening signal; and when the vehicle slips, the vehicle body electronic stabilizing system controls a motor of the vehicle to reduce torque or controls the vehicle to brake according to the slip rate of the vehicle. According to the vehicle driving control system, the slip rate of the vehicle is detected in the crawling manner, and the vehicle is controlled according to the slip rate, so that the vehicle cansafely and comfortably run in a crawling mode, and the vehicle can comfortably and stably run on an ice surface or a low-adhesion road surface.
本发明公开了一种车辆行驶控制系统及其控制方法、车辆,车辆行驶控制系统,其特征在于,包括:车身电子稳定系统,车身电子稳定系统用于检测车辆的油门踏板动作和制动踏板动作,在油门踏板和制动踏板均未被踩下时,车身电子稳定系统根据轮速信号判断车辆是否在进行蠕行驾驶;整车控制器,在车身电子稳定系统判断车辆在蠕行驾驶时,整车控制器用于输出加速油门开度信号;在车辆打滑时,车身电子稳定系统根据车辆的滑移率,控制车辆的电机降低扭矩或控制车辆制动。根据本发明的车辆行驶控制系统,通过在蠕行模式下检测车辆的滑移率,根据滑移率对车辆进行控制,使车辆可以安全舒适的蠕行行驶,使车辆在冰面或者低附路面舒适,平稳驾驶。
