The invention relates to the technical field of vehicle control, and discloses a vehicle control method and system for rainy and snowy weather and a vehicle terminal. According to the method, the weather related parameters corresponding to the target vehicle are obtained, and if the weather related parameters meet the preset first-level judgment condition, snowfield identification is performed on the road surface on which the target vehicle runs to obtain the wet and slippery road surface area in the road surface, so that when the target vehicle runs in the wet and slippery road surface area, snowfield identification is performed on the target vehicle. If yes, the target vehicle is controlled to start an automatic braking function, if the weather related parameters meet the rain and snow weather conditions, it is judged that accumulated snow possibly appears on the road surface, then snowfield recognition is conducted on the road surface where the target vehicle runs, and a wet and slippery road surface area is obtained; and the target vehicle is controlled to be braked according to the collision risk level, automatic emergency braking of the vehicle in the wet and slippery road area is achieved, obstacle avoidance support is provided for the vehicle in the wet and slippery road area, and therefore the vehicle running safety is improved.

    本申请涉及车辆控制技术领域,公开了一种针对雨雪天气的车辆控制方法、系统及车辆终端。本申请通过获取目标车辆对应的天气相关参数,并若天气相关参数满足预设的一级判定条件,对目标车辆所行驶的道路路面进行雪地识别,得到道路路面中的湿滑路面区域,从而当目标车辆行驶于湿滑路面区域,则控制目标车辆开启自动制动功能,若天气相关参数满足雨雪天气条件,则判断路面可能出现积雪,从而对目标车辆所行驶的道路路面进行雪地识别,得到湿滑路面区域,并当车辆处于湿滑路面区域时,根据碰撞风险等级控制目标车辆进行制动,实现了车辆在湿滑路面区域的自动紧急制动,为处于湿滑路面区域的车辆提供避障支持,从而提高车辆行驶的安全性。
