HYBRID VEHICLE OPERATION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a hybrid vehicle operation control method capable of making energy utilization ability of the vehicle active and intelligent for using energy efficiently, for improving fuel consumption of the vehicle.SOLUTION: The hybrid vehicle operation control method comprises: a high area SOC (state of charging); a middle area SOC; a low area SOC; and engine target torques corresponding to the respective SOC areas. The method calculates the engine target torque based on the current SOC, when the current SOC is equal to or more than a predetermined range, the engine target torque is reduced. When the SOC is equal to or less than the predetermined range, the engine target torque is increased. The SOC areas are further divided into fine part areas divided by vehicle speed, the engine target torque can be set for every fine part area.
