Method and device for vehicles safely passing through intersections

Abstract

The application discloses a method and a device for safely passing a vehicle through an intersection, belonging to the technical field of vehicle control. The method includes: when the state of the traffic light is green, acquiring the countdown of the green light; based on the distance between the target vehicle and the intersection cut-off line and the driving speed of the target vehicle, determining that the target vehicle travels to the crossroad When the countdown of the green light is greater than or equal to the sum of the time when the target vehicle travels to the intersection cut-off line and the first preset time, a prompt message is sent to remind the driver that the target vehicle can pass safely by maintaining the current speed crossroads. The present application can avoid the problem of running red when the driver judges that the vehicle can safely pass through the intersection, but in fact the vehicle cannot safely pass through the intersection in the prior art.

Description

technical field [0001] The present application relates to the field of vehicle control, in particular to a method and device for a vehicle to safely pass through an intersection. Background technique [0002] When the vehicle travels to an intersection with traffic lights, the driver often cannot grasp the time of the green light ahead, so that the driver cannot correctly judge whether the vehicle can pass safely. In the case of safely passing through the intersection, the driver controls the vehicle to pass through the intersection, but during the process of the vehicle passing through the intersection, the traffic light changes from green to red. In this case, the vehicle can only continue driving, which will cause the vehicle to run through the red light , easily lead to traffic accidents. Contents of the invention [0003] The embodiment of the present application provides a method and device for a vehicle to safely pass through an intersection, which can solve the pr...
