The invention provides a vehicle driving track prompting method and device. The method comprises the steps of: obtaining a pre-judgment driving track of a target vehicle passing through an intersection if the target vehicle is located at the intersection; determining a to-be-detected area according to the pre-judgment driving track; detecting whether a potential safety hazard exists in the to-be-detected area, and if the potential safety hazard exists in the to-be-detected area, determining projection position information according to the real-time driving information of the target vehicle and / or the pre-judgment driving track; and adjusting projection equipment according to the projection position information and the position information of the projection equipment, and controlling the projection equipment to project a warning image. The to-be-detected area is the area where the target vehicle passes when passing through the intersection, if the potential safety hazards are detected in the to-be-detected area, a warning image is projected to the position where the target vehicle is about to pass, so that pedestrians and vehicles can be warned,and accidents caused when other vehicles or pedestrians arrive at the position where the target vehicle is about to pass are avoided.
Description
technical field [0001] The invention relates to the technical field of safe driving of motor vehicles, in particular to a method and a device for prompting vehicle driving tracks. Background technique [0002] At intersections, the complexity of traffic flow and people flow increases, and traffic accidents such as collisions and scratches are prone to occur. When a vehicle passes through an intersection, it can use the turn signals to inform the vehicles behind of the driving path, thereby avoiding rear-end collisions. However, when the vehicle passes through the intersection, pedestrians cannot accurately predict the vehicle's driving trajectory, and there is a certain risk of collision. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that pedestrians cannot accurately predict the vehicle's driving trajectory in the prior art, so as to provide a vehicle driving trajectory prompting method ...
