Embodiment 1
[0221] by figure 1 Take the scenario as an example, the specific steps are as follows:
[0222] S1: Lane change data collection and lane change demand judgment:
[0223] a1. Lane changing data collection: figure 1 medium vehicle V 1 -V 3 During the driving process, the road condition information is collected by the lane change data acquisition module, and the vehicle V 1 The speed is 10m / s, the desired speed is 13.9m / s, and the acceleration is 1.4m / s 2 , 23m away from point b, and the distance from the leading vehicle V 2 16m, distance V 3 4 meters, leading vehicle V 2 The velocity is 14.4m / s and the acceleration is 0.6m / s 2 , lagging the vehicle V 3 The speed is 12.5m / s and the acceleration is 0.9m / s 2 . ;
[0224] a2. Judgment of lane-changing demand: judge whether the vehicle has a lane-changing demand according to the following formula:
[0225]
[0226]
[0227] Among them, Δx i Indicates the current vehicle V 1 with the leading vehicle V 2 Or the r...
