The invention discloses a driving anti-slip control method and system with overlapped control modes in multiple scenes, and relates to the technical field of automobile safe driving, and the method comprises the steps: if a single-side driving wheel is in a slip working condition, increasing the braking torque to slip driving wheels, and then increasing the driving torque to all the slip driving wheels; if the working condition is out of order, increasing the braking torque to the slip driving wheels, then increasing the driving torque to all the slip driving wheels, judging whether the rotating speed of the steering wheel is increased to be the same as the rotating speed of the driving wheels or not, and if yes, ending the control operation; and if not, the driving torque of all the driving wheels is increased by reducing the rotating speed of the engine and increasing the output torque of the engine. Different control operations are output for the vehicles in different real-time states, the pertinence of driving skid resistance is improved, and under the out-of-trouble working condition, engine flameout caused by too high engine rotating speed is avoided by reducing the engine rotating speed and increasing the output torque of the engine.
本申请公开了一种多场景下控制模式叠加的驱动防滑控制方法及系统,涉及汽车安全驾驶技术领域,包括若单侧驱动轮滑转工况,则增加对滑转驱动轮的制动力矩后,增加对所有滑转驱动轮的驱动力矩;若脱困工况,则增加对滑转驱动轮的制动力矩后,增加对所有滑转驱动轮的驱动力矩,判断转向轮的转速是否提升至与驱动轮的转速相同,若是,则结束控制操作;若否,则通过降低发动机转速并增加发动机的输出扭矩增加对所有驱动轮的驱动力矩。本申请通过对不同实时状态的车辆输出不同的控制操作,提高驱动防滑的针对性,并在脱困工况下,通过降低发动机转速并增加发动机的输出扭矩,避免因发动机转速过高导致发动机熄火。
