The invention relates to a lane speed limit reminding method and device. The method comprises the steps that transverse displacement of a vehicle within a preset time period before the current moment is obtained; determining the difference between the number of lane lines on the left and right sides of the vehicle at the current moment and the number of lane lines on the left and right sides of the vehicle at the previous moment according to the acquired lane line image in front of the vehicle; acquiring a steering shift lever signal in a preset time period; according to the transverse displacement, the difference of the number of the lane lines and the signal of the steering deflector rod, whether the vehicle changes lanes or not is determined; and a speed limit value matched with the current lane is obtained from lane speed limit information collected in advance, and speed limit reminding information is generated based on the speed limit value. According to the scheme, the speed limit value matched with the current lane is obtained from the lane speed limit information, and the speed limit reminding information is generated, so that corresponding traffic speed limit reminding is performed when a driver drives on different lanes, the workload of recognizing a road speed limit board by the driver is reduced, and legal driving of the driver is regulated to avoid an overspeed phenomenon.

    本发明涉及了一种车道限速提醒方法和装置,该方法包括:获取车辆在当前时刻之前的预设时间段内的横向位移;根据采集的车辆前方的车道线图像,确定当前时刻车辆左右两侧的车道线数量与上一时刻车辆左右两侧的车道线数量的差异;获取预设时间段内的转向拨杆信号;根据横向位移、车道线数量的差异、转向拨杆信号,确定车辆是否发生了变道;从预先采集的车道限速信息中获取与当前车道匹配的限速值,并基于限速值生成限速提醒信息。本方案从车道限速信息中获取与当前车道匹配的限速值,并生成限速提醒信息,从而对驾驶员行驶在不同车道时进行对应的交通限速提醒,减少了驾驶员识别道路限速牌的工作量,规范驾驶员合法行驶以避免超速现象。
