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 guaranteed that data are updated in real time in the automobile speed changing process, safety can be improved, real-time performance can be guaranteed, meanwhile the calculation method can be combined with other intelligent auxiliary driving technologies to form a more intelligent and effective function, and user experience is enhanced.

    本发明涉及一种汽车智能辅助驾驶换道预警的计算方法,包括以下步骤:步骤a、设定在汽车智能辅助驾驶换道系统中设定安全距离;步骤b、当主车进行或者即将进行换道时,分别预估目标车道上的前车与后车之间的距离;步骤c、当预估目标车道上的前车与后车之间的距离小于设定的安全距离时,则发出警告信息,同时禁止变道操作;当预估目标车道上的前车与后车之间的距离大于设定的安全距离时,则可进行变道操作。该汽车智能辅助驾驶换道预警的计算方法,占用计算资源较低,同时能够保证在车速变化的过程中实时更新数据,既可以提高安全性又可以保证实时性,同时可以与其它智能辅助驾驶技术结合,形成更加智能有效的功能,增强用户的使用体验。
