The invention discloses a speed limit reminding method and device on a high-speed main road, and belongs to the field of safe driving. The method comprises the steps that when a vehicle runs on a highway, the position of a front speed limit board and a speed limit value are recognized through a camera; judging whether the speed limit value is the ramp speed limit or not, and reminding a driver of the corresponding speed limit value when the speed limit value is not the ramp speed limit; when the speed limit value is ramp speed limit, further judging whether a driver intends to get off the ramp or not; when the driver intends to get off the ramp, the driver is reminded of the corresponding speed limit value; and when the driver does not have the intention of getting off the ramp, the corresponding speed limit value is not reminded. According to the invention, the accuracy of speed limit reminding of the high-speed main road is improved, interference to a driver caused by false alarm of an instrument in high-speed driving is avoided, and high-speed driving safety is provided.

    本发明公开了一种高速主路上的限速提醒方法及装置,属于安全驾驶领域。所述方法包括:车辆在高速路上行驶时,通过摄像头识别前方限速牌的位置及限速值;判断所述限速值是否为匝道限速,当所述限速值不为匝道限速时,提醒驾驶员对应的限速值;当所述限速值为匝道限速时,进一步判断驾驶员是否有下匝道意图;当驾驶员有下匝道意图时,提醒驾驶员对应的限速值;当驾驶员无下匝道意图时,对应的限速值不进行提醒。本发明提高了高速主路限速提醒的准确率,避免高速行车中的仪表误报警对驾驶员造成干扰,提供了高速行车安全。
