The invention discloses a speed limit reminding method and system, and relates to the technical field of vehicle engineering.The speed limit reminding method comprises the steps that a speed limit identifier is obtained, and a current speed limit value is determined; when a ramp fork exists within a preset distance in front of a vehicle, according to the state of a steering lamp, a driver monitoring system DMS detects whether a driver observes the action of a right rearview mirror, signals of a steering wheel angle sensor, the current vehicle speed, the opening degree of an accelerator pedal or a brake pedal and the distance from the vehicle position to the ramp fork; judging whether the driver intends to drive into the ramp fork; if yes, the current speed limit value is displayed to a driver. The speed limit reminding system comprises an acquisition module, a judgment module and a speed limit reminding module. According to the speed limit reminding method and system, the driving intention of a driver is fully considered, the situation of false alarm caused by interference of other road speed limit values is reduced, and the driving experience and safety are improved.

    本申请公开了一种限速提醒方法及系统,涉及车辆工程技术领域,该限速提醒方法包括:获取限速标识,并确定一个当前限速值;当车辆前方预设距离内有匝道岔路口时,根据转向灯状态、驾驶员监控系统DMS检测驾驶员是否有观察右侧后视镜动作、方向盘转角传感器信号、当前车速、加速踏板或制动踏板的开度、以及车辆位置至匝道岔路口的距离,判断驾驶员是否有驶入匝道岔路口的意图;若是,则对驾驶员显示该当前限速值。该限速提醒系统包括获取模块、判断模块和限速提醒模块。本申请的限速提醒方法及系统,充分考虑了驾驶员的行驶意图,减少了其他道路限速值干扰导致误报的情况,提升了驾乘体验和安全性。
