Abstract

The invention provides an overtaking pre-judgment method and a terminal. The method comprises steps of: acquiring a first initial distance between the head of a host vehicle and the tail of a first vehicle before a lane change, wherein the first vehicle drives in a lane where the host vehicle is located and ahead of the host vehicle along a direction the same as that of the host vehicle; calculating a first predicted distance between a target vehicle and a second vehicle after the host vehicle overtakes, wherein the target vehicle is the host vehicle or the first vehicle, and the second vehicle drives in an adjacent lane and ahead of the host vehicle; and outputting an overtaking prompt if the first initial distance is greater than or equal to a preset safety distance and the first predicted distance is greater than or equal to the preset safety distance. Before the host vehicle overtakes, the method makes pre-judgment and outputs the overtaking prompt if the first initial distance isgreater than or equal to the preset safety distance and the first predicted distance is greater than or equal to the preset safety distance, thereby reducing the probability of traffic accidents during overtaking and well ensuring the safety of the overtaking vehicle.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an overtaking prediction method and a terminal. Background technique [0002] At present, the traffic situation on the road is very complicated. In order to ensure safety, it is necessary for the car to obtain as much information about the surrounding vehicles as possible. In the process of driving, there are often situations that require overtaking, and many traffic accidents are caused by overtaking. For example, when overtaking, the car changes lanes to the adjacent lane, and the vehicle on the adjacent lane is traveling in the opposite direction to the vehicle making the lane change. If the speed of the vehicle on the adjacent lane is fast, and the distance between the vehicle after the lane change and the vehicle on the adjacent lane is small, it is likely that the vehicle after the lane change will not return to the original lane in time. A collision with an oncoming vehicle. ...
