A vehicle underpinning early warning method and a vehicle are used for informing a driver of underpinning risks of the vehicle in advance, and the method comprises the following steps: the vehicle in a driving state receives road information in a coverage range sent by roadside equipment; for at least one piece of ramp data in the road information, according to a ramp angle in the ramp data and size data of the vehicle, simulating a critical size value of a vehicle touch area when the vehicle is located at a set position of a ramp corresponding to the ramp data and has a bottoming risk; if the actual size value of the vehicle in the vehicle touch area is not smaller than the critical size value, it is determined that the bottom supporting risk exists when the vehicle runs to the set position; and before the vehicle arrives at the ramp, early warning information that the vehicle has the risk of underpinning is sent out.

    一种车辆托底预警方法及车辆,用以提前告知驾驶员车辆的托底风险,该方法包括:处于行驶状态的车辆接收路侧设备发送的覆盖范围内的道路信息;针对所述道路信息中的至少一个坡道数据,根据所述坡道数据中的坡道角度和所述车辆的尺寸数据,模拟所述车辆处于所述坡道数据对应的坡道的设定位置且存在托底风险时,车辆触碰区域的临界尺寸值;若所述车辆在所述车辆触碰区域的实际尺寸值不小于所述临界尺寸值,则确定所述车辆行驶至所述设定位置时存在托底风险;在所述车辆到达所述坡道前,发出所述车辆存在托底风险的预警信息。
