The invention discloses an L2-level automatic driving gear control method of a drive-by-wire gear electric vehicle. A state signal, radar data, positioning data and cloud data are obtained; judging a scene state according to the state signal, the radar data, the positioning data and the cloud data; the scene state comprises an automatic parking scene, an ACC (adaptive cruise control) scene, an intelligent network connection traffic light intersection scene and a manual takeover scene; and according to the scene state, the state signal, the radar data, the positioning data and the cloud data, vehicle gear switching is carried out. The invention further discloses an L2-level automatic driving gear control system of the drive-by-wire gear electric vehicle. According to the invention, a gear switching function in an L2-level automatic driving strategy can be realized; auxiliary fusion is carried out for an automatic driving strategy and a vehicle-road cooperation scheme, and the method is suitable for various automatic driving scenes.

    本发明公开一种线控档位电动车的L2级自动驾驶档位控制方法,获取状态信号、雷达数据、定位数据和云端数据;根据状态信号、雷达数据、定位数据和云端数据,判断场景状态;所述场景状态包括自动泊车场景、ACC自适应巡航场景、智能网联红绿灯路口场景和人工接管场景;根据场景状态、状态信号、雷达数据、定位数据和云端数据,进行车辆档位切换。本发明还公开一种线控档位电动车的L2级自动驾驶档位控制系统。本发明能实现L2级别自动驾驶策略中的档位切换功能;针对自动驾驶策略及车路协同方案做出辅助性融合且适用于各种自动驾驶场景。
