The invention discloses an EPS takeover control method and system based on intelligent driving and an automobile. The method comprises the following steps: establishing and storing automatic driving exit hand power calculation models corresponding to different vehicle speed ranges; according to the ADS signal and the capacitive sensing steering wheel module signal, whether the intelligent EPS takeover control function is started or not is judged; after the intelligent EPS takeover control function is started, whether the real-time turning angle of a steering wheel is larger than a set angle or not is judged every driver takeover interpretation time within driver takeover time, and if yes, automatic driving starts to exit; determining a vehicle speed range according to the current speed, extracting a corresponding calculation model, and calculating an automatic driving exit hand force; and the automatic driving is gradually quitted according to the automatic driving quitting hand force. According to the characteristics of the automatic driving system, the intelligent control logic is adopted to effectively recognize the driver takeover intention, the problem that the driver takeover hand force is large and poor in hand feeling is solved, and the safety of the automatic driving function in the driver takeover process is improved.
本申请公开了一种基于智能驾驶的EPS接管控制方法、系统及汽车。该方法可以包括:建立不同车速范围对应的自动驾驶退出手力的计算模型并保存;根据ADS信号与电容感应方向盘模块信号,判断智能EPS接管控制功能是否开启;智能EPS接管控制功能开启后,在驾驶员接管时间内每隔驾驶员接管判读时间判断方向盘实时转角是否大于设定角度,若是,则开始退出自动驾驶;根据当前速度确定车速范围,进而提取对应的计算模型,计算自动驾驶退出手力;根据自动驾驶退出手力逐步退出自动驾驶。本发明可针对自动驾驶系统特性,采用智能控制逻辑有效识别驾驶员接管意图,改善驾驶员接管手力大手感差问题,提升自动驾驶功能由驾驶员接管过程中的安全性。
