The invention relates to the technical field of vehicle speed control, in particular to a vehicle speed limiting control method and system and an all-terrain vehicle, and the vehicle speed limiting control method comprises an ECU used for monitoring a vehicle gear, an engine rotating speed N and a throttle opening theta, and if the vehicle gear is in a reverse gear, and the engine rotating speed N is lower than a preset rotating speed or the throttle opening theta is lower than a preset opening, vehicle speed limiting control is not carried out. According to the scheme, the speed limiting strategy can be flexibly adjusted according to the actual operation working condition of the vehicle, flameout of the engine under the reversing idling working condition is effectively prevented, the overall performance and stability of the vehicle are greatly improved, the problem that the engine flames out when a user backs up on a ramp at a low speed when a reverse gear is engaged is solved, and the user experience is improved. The commodity and user satisfaction of the vehicle are improved, and the market competitiveness of the vehicle is enhanced.

    本发明涉及车速控制技术领域,具体为一种车辆限速控制方法、系统及全地形车,包括:ECU,用于监测车辆挡位、发动机转速N和节气门开度θ,若车辆挡位处于倒挡,且发动机转速N低于预设转速或节气门开度θ低于预设开度,则不进行车辆限速控制。本方案能够根据车辆的实际运行工况灵活调整限速策略,有效防止发动机在倒车怠速工况下熄火,极大地提升了车辆的整体性能和稳定性,以解决用户在挂入倒挡在坡道上低车速倒车时发动机熄火的问题,提高车辆的商品性和用户满意度,增强车辆的市场竞争力。
