The invention provides a control method and system capable of adjusting the maximum vehicle speed limit and a vehicle, and belongs to the technical field of vehicle speed control. Judging whether the vehicle is in a speed limiting state; when the actual vehicle speed value exceeds the maximum vehicle speed limit value, an alarm state is given out; when the vehicle reaches the speed limiting state, the torque value required by the wheel end is calculated and output; in combination with the current vehicle state, wheel end output torque values corresponding to the maximum output torque and the minimum output torque of the engine are calculated, and the wheel end torque values are limited; after the vehicle enters the speed limiting state, the value of the request torque output to the engine is the small value of the calculated torque value and the calculated torque value of the accelerator pedal in the speed limiting state; and when the vehicle is in the speed limiting state, the output torque value of the engine is limited. The vehicle speed limiting device has a vehicle speed limiting function and can limit the highest driving vehicle speed of the vehicle. In different speed limiting scenes, the maximum vehicle speed limiting value can be conveniently adjusted, and the use requirement is met.
本发明提供一种可调最高车速限制的控制方法、系统及车辆,属于车速控制技术领域,设置车辆最高车速限制值;判断车辆是否处于限速状态;当车辆实际车速值超过最高车速限制值时,发出报警状态;当车辆达到限速状态时,计算并输出轮端需求的扭矩值;结合当前车辆状态,计算出与发动机最大和最小输出扭矩相对应的轮端输出扭矩值,并限制轮端扭矩值;当车辆进入限速状态后,输出给发动机请求扭矩的取值为限速状态下的油门踏板计算扭矩值与计算扭矩值的小值;车辆在限速状态下,限制发动机的输出扭矩值。本发明有车速限制功能,能够对车辆的最高行驶车速进行限制。在不同的限速场景下,最高车速限制值可以方便的进行调节,满足使用要求。
