The invention discloses a reminding method for preventing an ultrahigh vehicle running on an auxiliary road from driving into a height-limiting road section. The reminding method comprises the steps that firstly, whether a height-limiting condition exists in front of a road where the vehicle runs or not is detected according to real-time position information of the vehicle and information of the road where the vehicle runs; then, according to the main road speed limit v1 and the auxiliary road speed limit v2 of the current road where the vehicle runs and the vehicle speed vi of the vehicle, whether the vehicle runs on the auxiliary road or not is judged; the method further includes judging whether the vehicle approaches the height limiting position or not according to the vehicle positionand the height limiting position; if the vehicle is close to the height limiting position, judging whether the vehicle can smoothly pass through the height limiting position or not; and if the vehiclecannot safely pass through the height limit, performing early warning on the driver of the vehicle according to the time distance between the vehicle position and the height limit position. Accordingto the invention, effective early warning can be carried out on the ultrahigh vehicle which is close to the height limiting position and cannot pass through the height limiting position.
本发明公开了一种用于避免辅路上行驶的超高车辆驶入限高路段的提醒方法:首先根据自车的实时位置信息和自车所行驶的道路信息,检测车辆所行驶的道路前方是否存在限高状况;然后根据自车所行驶的当前道路的主路限速v、辅路限速v和自车车速v,判断自车是否在辅路上行驶;再根据自车位置和限高位置,判断自车是否驶近限高位置;若自车已经驶近限高位置,判断自车是否可以顺利通过限高;若自车无法安全通过限高,根据自车位置与限高位置的时间距离,对自车驾驶人进行预警。本发明可对已经接近限高位置且不能通过限高的超高车辆进行有效预警。
