The embodiment of the invention discloses an intersection decision-making method and device for a vehicle. The method comprises the steps of querying high-precision map data of a lane where a target vehicle is located at a first moment; according to the high-precision map data, acquiring state information of a signal lamp at an intersection in front of the target vehicle on the lane at the first moment and the distance from the target vehicle to the intersection; determining a drivable speed interval of the target vehicle from the initial position to the intersection according to the state information of the intersection signal lamp and the distance from the target vehicle to the intersection; and if the drivable speed interval is within the vehicle speed interval range allowed by the lane, determining the execution speed of the target vehicle according to the drivable speed interval. Compared with the situation that the driver subjectively judges whether the vehicle can pass through the intersection or not, the instantaneous acceleration of the vehicle is too large, the driver cannot accurately estimate the passing speed of the vehicle, and consequently the vehicle cannot pass through, the efficiency of the target vehicle passing through the intersection is improved, and the comfort of passengers in the vehicle is improved.

    本说明书实施例公开了车辆的路口决策方法及装置,包括:查询第一时刻目标车辆所在车道的高精度地图数据;根据高精度地图数据,获取第一时刻车道上位于目标车辆前方的路口的信号灯的状态信息、以及目标车辆到路口的距离;根据路口信号灯的状态信息与目标车辆到路口的距离,确定目标车辆从初始位置到路口的可行驶速度区间;若可行驶速度区间位于车道允许的车速区间范围内,则根据可行驶速度区间确定目标车辆的执行速度。本说明书实施例相比通过驾驶员主观判断能否通过路口,导致车辆瞬间加速度过大以及驾驶员无法准确预估车辆通过速度导致无法通过等情况,提高了目标车辆通过路口的效率以及车内乘客的舒适性。
