APPARATUS AND METHOD FOR CONTROLLING OPERATING POINT OF HYBRID ELECTRIC VEHICLE
First Claim
1. A method for controlling an operating point of a hybrid electric vehicle, comprising:
- detecting, by a controller, a demand torque of a driver;
determining, by the controller, a charging and discharging tendency by calculating a moving average based on the demand torque;
reflecting, by the controller, system efficiency using a dynamical event capture and leveling the charging and discharging tendency;
determining, by the controller, a compensation amount of the operating point based on the leveling of the charging and discharging tendency; and
adjusting, by the controller, the operating point of the hybrid electric vehicle based on the compensation amount of the operating point.

Abstract
An apparatus and a method for controlling an engine operating point of a hybrid electric vehicle are provided to determine charging and discharging tendency based on a moving average of an engine torque and a demand torque as well as a dynamical event capture. The method includes detecting a demand torque of a driver and determining a charging and discharging tendency by calculating a moving average based on the demand torque. System efficiency is then reflected using a dynamical event capture and the charging and discharging tendency is leveled. A compensation amount of the operating point is also determined based on the leveling of the charging and discharging tendency and the operating point of the hybrid electric vehicle is adjusted based on the compensation amount of the operating point.
