The invention relates to the technical field of automobile speed limiting, in particular to an intelligent active speed limiting system and method and a vehicle. The intelligent active speed limiting method comprises the steps that a detection module is used for detecting the speed limiting value of a current road of the vehicle and the current wheel speed of the vehicle, and the speed limiting value and the current wheel speed are sent to a control module; the control module is used for receiving the current wheel speed, converting the current wheel speed into the whole vehicle speed and sending the whole vehicle speed to the speed limiting module; and receiving the whole vehicle speed through a speed limiting module, and limiting the whole vehicle speed of the vehicle based on the speed limiting value when the whole vehicle speed is greater than the speed limiting value. Therefore, the problems that the cruise speed set by the driver exceeds the speed limit requirement, traffic accidents or violation of rules are caused and the like due to the fact that the driver may not see or ignore the road speed limit sign due to the fact that the driver is blocked by obstacles or distracted and the like in the process of driving the vehicle by using a constant speed cruise or traffic jam auxiliary function are solved; by adjusting the speed limiting function of the engine, active speed limiting of the whole vehicle is achieved.

    本申请涉及汽车限速技术领域,特别涉及一种智能主动限速系统和方法、车辆,包括:利用检测模块检测车辆的当前道路的限速值和车辆的当前轮速,并将限速值和当前轮速发送至控制模块;利用控制模块接收当前轮速,将当前轮速换算为整车车速,并将整车车速发送至限速模块;通过限速模块接收整车车速,并在整车车速大于限速值时基于限速值限制车辆的整车车速。由此,解决了驾驶员使用定速巡航或交通拥堵辅助功能驾驶车辆的过程中,由于障碍物遮挡或分心等原因,可能会看不到或忽略道路限速标识,从而导致驾驶员设置的巡航车速超过限速要求,造成交通事故或违章等问题,通过对发动机限速功能的调整,实现整车主动限速。
