Claim 2:
3. The method according to claim 1, wherein before the step of determining a collision distance between the first vehicle and the second vehicle according to the lane change state, the current position of the first vehicle and a series of data points of the second vehicle, the method further comprises:
determining a data point with the smallest distance from the current position of the first vehicle from the series of data points as the nearest data point according to a series of positions of the second vehicle and the current position of the first vehicle;
determining target data points from the series of data points according to the nearest data point, wherein the target data points comprise the nearest data point and data points collected after the nearest data point;
respectively calculating the distance between the vehicle positions corresponding to every two adjacent data points in the target data points to obtain a plurality of two-point distances, and using the sum of the plurality of two-point distances as a first distance;
the step of determining a collision distance between the first vehicle and the second vehicle according to the lane change state, the current position of the first vehicle and a series of data points of the second vehicle comprises:
when the lane change state indicates that the second vehicle has not changed lanes in the historical path, determining whether the second vehicle and the first vehicle are in the same lane;
when determining that the second vehicle has not changed lanes in the historical path, and the second vehicle and the first vehicle are located in the same lane, taking the first distance as the collision distance.
