The invention relates to a calculation method for intelligent auxiliary driving lane changing early warning of an automobile. The calculation method comprises the following steps: a, setting a preset safety distance in an automobile intelligent auxiliary driving lane changing system; b, when the main vehicle changes the lane or is about to change the lane, estimating the distance between the front vehicle and the rear vehicle on the target lane; and c, when the distance between the front vehicle and the rear vehicle on the estimated target lane is smaller than the preset safe distance, sending out warning information, and meanwhile forbidding lane changing operation; and when the distance between the front vehicle and the rear vehicle on the estimated target lane is greater than a set safety distance, carrying out lane changing operation. According to the calculation method for intelligent auxiliary driving lane changing early warning of the automobile, occupied calculation resources are low, it can be guaran
