The invention provides an electric vehicle lane departure early-warning correction method and device, and belongs to the technical field of electric vehicle driving assistance. When a vehicle can execute a lane departure early-warning correction function, corresponding preset triggering conditions are determined according to different function intensity levels, and when the preset triggering conditions are met, the lane departure early-warning correction function is executed. Initial lane departure early warning corresponding to the function intensity level is executed, when execution exceeds a preset time threshold value but the vehicle still has a lane departure condition, it is indicated that a driver does not respond to the initial lane departure early warning, and at the moment, enhanced lane departure early warning is further executed; if the driver does not respond to the enhanced lane departure warning, lane departure correction is performed. The electric vehicle lane departure early warning and correction method is high in flexibility, different trigger conditions can be set according to different functional strength levels, and departure early warning can be performed in a layered manner, so that lane departure can be effectively early warned and corrected.

    本申请提供了一种电动汽车车道偏离预警修正方法及装置,属于电动汽车驾驶辅助技术领域,当车辆能够执行车道偏离预警修正功能时,根据不同的功能强度级别确定对应的预设触发条件,当满足预设触发条件时,执行与功能强度级别对应的初始车道偏离预警,当执行超过预设时间阈值但车辆仍旧存在车道偏离情况时,则说明驾驶员并没有对初始车道偏离预警作出反应,此时则进一步执行增强车道偏离预警,如果驾驶员对增强车道偏离预警仍旧没有作出反应,则执行车道偏离修正。本申请提供的电动汽车车道偏离预警修正方法的灵活度较高,能够根据不同的功能强度级别设置不同的触发条件,且能够分层进行偏离预警,从而有效对车道偏离进行预警和修正。
