The invention relates to the technical field of automatic driving, in particular to a method for dynamically adjusting the performance of an automatic driving target in rainy and snowy weather, which comprises the following steps: identifying the rainy and snowy weather of the current vehicle driving position; acquiring a weather AD performance parameter correction coefficient according to the currently identified rain and snow weather; according to the obtained correction coefficient, a target car following time interval, a brake filtering coefficient and a distance limit value of a car before/after lane changing set by the ACC are corrected so as to realize dynamic adjustment of target performance, the rain and snow weather condition is taken as an important input of the method, a control target is dynamically adjusted according to the weather condition within an automatic driving Operating Design Domain (Operation Design Domain), and the dynamic adjustment of the target performance is realized. And normal operation of the system and vehicle/personnel safety are ensured.
本发明涉及自动驾驶技术领域,尤其涉及一种雨雪天气下自动驾驶目标性能动态调节的方法,包括对当前车辆行驶位置雨雪天气进行识别;根据当前识别的雨雪天气,获取该天气AD性能参数修正系数;根据获取的修正系数,对ACC设定的目标跟车时距,刹车滤波系数,换道前/后车距离限值进行修正,以实现目标性能动态调节,雨雪天气情况作为本发明的一个重要输入,在自动驾驶OperationalDesignDomain(运行设计域)以内,根据天气情况动态调整控制目标,以保证系统正常运行以及车辆/人员安全。
