The invention discloses an intelligent networked PHEV energy management method and system based on security situation assessment. The method comprises the following steps: 1) acquiring vehicle driving condition data; 2) calculating vehicle safety situation evaluation parameters based on the vehicle driving condition data; 3) determining the current driving state of the vehicle according to the vehicle safety situation evaluation parameters; 4) generating a vehicle energy management scheme based on the current driving state of the vehicle; 5) monitoring the driving condition data of the front vehicle in real time, and if the driving state of the front vehicle is changed, returning to the step 2); and if the front vehicle is kept in the current driving state, returning to the step 2) after t time. The system comprises a vehicle driving condition data acquisition unit, a vehicle safety situation evaluation parameter calculation unit, a driving state judgment unit and a vehicle energy management scheme generation and execution unit. The invention provides an energy management strategy based on security situation assessment, and provides theoretical and technical support for realizing deep fusion of a PHEV technology and an intelligent network connection technology.

    本发明公开基于安全态势评估的智能网联PHEV能量管理方法及系统,方法步骤包括:1)获取车辆行驶工况数据;2)基于所述车辆行驶工况数据,计算车辆安全态势评价参数;3)根据车辆安全态势评价参数确定车辆当前行驶状态;4)基于车辆当前行驶状态,生成车辆能量管理方案;5)实时监测前车行驶工况数据,若前车行驶状态改变,则返回步骤2);若前车保持当前行驶状态,则间隔t时间后返回步骤2)。系统包括车辆行驶工况数据获取单元、车辆安全态势评价参数计算单元、行驶状态判断单元、车辆能量管理方案生成与执行单元;本发明提出基于安全态势评估的能量管理策略,为实现PHEV技术和智能网联技术深度融合提供理论和技术支撑。
