The invention discloses an expressway ramp speed limit control method and system, a vehicle and a storage medium, and the method comprises the steps: shielding ramp speed limit board information on a ramp section when determining that a vehicle does not pass through a ramp to leave a main road, and if the vehicle does not run on a ramp side lane when determining that the vehicle needs to pass through the ramp to leave the main road, recommending a driver to change a lane to a ramp side lane in advance; only when confirming that the vehicle needs to pass through the ramp and runs on the ramp side lane at the same time, considering the information of the speed limit board on the ramp section to be effective, displaying the speed limit information, and when confirming that the vehicle needs to pass through the ramp to leave the main lane and runs on the ramp side lane, carrying out speed limit control when the vehicle is away from the ramp entrance by a reasonable distance. And when the ramp speed limit information is ensured to be accurately displayed, giving an overspeed alarm for reminding if an overspeed driving into the ramp exists, controlling the vehicle to drive according to the ramp speed limit value or the ramp safe speed when the vehicle is driven into the ramp, and giving an overspeed alarm for reminding when the vehicle is overspeed and passes through the ramp.
本发明公开了一种高速公路匝道限速控制方法、系统、车辆及存储介质,包括:在确定不通过匝道驶离主道时,屏蔽匝道路段上的匝道限速牌信息,在确定需要通过匝道驶离主道时,如果没有行驶在匝道侧车道,提前推荐驾驶员换道到匝道侧车道;只有在确认需要通过匝道,同时行驶在匝道侧车道,才认为匝道路段限速牌信息有效,并加以限速信息显示,在确定需要通过匝道驶离主道,且行驶在匝道侧车道,当距离匝道入口达到合理距离时才进行限速控制,在保证匝道限速信息显示准确的同时,如果存在超速驶入匝道情况就加以超速报警提醒,当已行驶到匝道中时,控制车辆按照匝道限速值或匝道安全车速行驶,当存在超速通过匝道时加以超速报警提醒。
