METHOD AND SYSTEM FOR CONTROLLING THE CHARGING OF A HYBRID VEHICLE

摘要

Disclosed is a method and a system for controlling charging of a hybrid vehicle which controls engine idle by using a starting/generating motor when a battery is charged. The method includes: determining a target charging to be charged in the battery by the starting/generating motor and a target torque of the starting/generating motor for generating the target charging amount based on a state of charge (SOC) of the battery and power consumption of a load of an electric device when the engine is idle; driving the engine by applying a command of torque corresponding to the target torque to the engine; detecting torque actually output from the starting/generating motor; calculating an error between the actual torque and the target torque; calculating an engine torque compensation value based on the calculated error; and feedback controlling an idle speed of the engine by adding the engine torque compensation value to the command of torque of the engine.
