The invention discloses a method and device for enabling a vehicle to safely pass through a crossroad, and belongs to the technical field of vehicle control. The method comprises the following steps: when the state of a traffic light is a green light, obtaining countdown of the green light; based on the distance between the target vehicle and the crossroad cut-off line and the driving speed of the target vehicle, enabling the time when the target vehicle to drive to the crossroad cut-off line is determined; and when the countdown of the green light is greater than or equal to the sum of the time for the target vehicle to drive to the crossroad cut-off line and the first preset time, sending a prompt message to prompt a driver that the target vehicle can safely pass through the crossroad while keeping the current driving speed. According to the application, the problem that in the prior art, when a driver judges that the vehicle can safely pass through the crossroad, but actually the vehicle cannot safely pass through the crossroad, the phenomenon of rushing into red is caused can be avoided.

    本申请公开了一种车辆安全通过十字路口的方法和装置,属于车辆控制技术领域。所述方法包括:当交通灯的状态为绿灯时,获取绿灯的倒计时;基于所述目标车辆与十字路口截止线之间的距离以及所述目标车辆的行驶速度,确定所述目标车辆行驶到十字路口截止线的时间;当绿灯的倒计时大于或等于目标车辆行驶到十字路口截止线的时间和第一预设时间之和时,发出提示消息以提示驾驶人员目标车辆保持当前行驶速度便能安全通过十字路口。本申请能够避免现有技术中在驾驶人员判断出车辆可以安全通过十字路口,但实际上车辆并不能安全通过十字路口的情况下,导致闯红色的现象发生的问题。
