The invention relates to the technical field of automobile active safety, in particular to a tunnel speed limiting method and device, a vehicle and a storage medium. The method comprises the steps that under the condition that the vehicle is in a self-adaptive cruise mode, the actual distance between a front tunnel and the vehicle and the tunnel speed limiting are obtained, and the current cruise speed of the vehicle is collected; calculating a speed difference value between the tunnel speed limit and the current cruising vehicle speed, and generating a deceleration strategy of the vehicle according to the speed difference value and the actual distance; and controlling the vehicle to decelerate according to the deceleration strategy so as to reduce the vehicle speed to the tunnel speed limit value when the vehicle arrives at the front tunnel. According to the embodiment of the invention, when the road in front of the vehicle is the tunnel, the difference value between the cruise speed and the tunnel speed limit in the self-adaptive cruise mode and the actual distance between the vehicle and the tunnel can be calculated, deceleration is completed in advance, the overspeed risk when a driver passes through the tunnel is avoided, traffic accidents are avoided, and the driving safety of the vehicle is improved. The life safety of the driver is ensured.

    本申请涉及汽车主动安全技术领域,特别涉及一种隧道限速方法、装置、车辆及存储介质,其中,方法包括:在车辆处于自适应巡航模式的情况下,获取前方隧道与车辆之间的实际距离和隧道限速,并且采集车辆的当前巡航车速;计算隧道限速和当前巡航车速之间的速度差值,并根据速度差值和实际距离生成车辆的减速策略;以及按照减速策略控制车辆减速,以在车辆抵达前方隧道时,将车速降低至隧道限速值。本申请实施例可以在车辆前方道路为隧道时,计算自适应巡航模式下的巡航车速和隧道限速之间的差值以及车辆与隧道之间的实际距离,提前完成减速,避免驾驶员经过隧道时的超速风险,避免交通事故的发生,提高车辆的行车安全,保证驾驶员的生命安全。
