soc hybrid vehicle control system and its control method

The present invention relates to a kind of a hybrid vehicle control system and control method SOC. The control system comprises: a feedforward compensating means for feed-forward compensation SOC SOC calculated according to the previous navigation information and feed forward compensation driving power P according to the previous history of the vehicle driving power curve and power curve determined drive current; an arithmetic unit, according to the front feedforward compensation SOC-vehicle bus to provide current SOC calculated SOC difference [Delta] SOC, the current driving power P fed offset drive power Pm supplied to the car bus driving power difference ΔP is calculated according to the front; fuzzy controller for current SOC, the SOC difference [Delta] SOC, and the driving power difference ΔP vehicle provided by the bus, the data obtaining operating point of the engine.
