SYSTEM AND METHOD FOR CONTROLLING HYBRID ELECTRIC VEHICLE USING DRIVING TENDENCY OF DRIVER

摘要

A system and method for controlling a hybrid electric vehicle using a driving tendency are provided. The method includes determining a driving tendency level based on data to determine a driving tendency of a driver and determining a target engine torque using an engine torque map based on a vehicle speed and a required torque. Whether the driving tendency level corresponds to a predetermined level is determined as well as whether the required torque is equal to or greater than a torque that corresponds to an optimal operating point of an engine when the driving tendency level corresponds to the predetermined level. The target engine torque is then adjusted when the required torque is equal to or greater than the torque that corresponds to the optimal operating point of the engine.

1. A method for controlling a hybrid electric vehicle using a driving tendency, comprising:
determining, by a controller, a driving tendency level based on data to determine a driving tendency of a driver; determining, by the controller, a target engine torque using an engine torque map based on a vehicle speed and a required torque; determining, by the controller, whether the driving tendency level corresponds to a predetermined level; determining, by the controller, whether the required torque is equal to or greater than a torque that corresponds to an optimal operating point of an engine when the driving tendency level corresponds to the predetermined level; and adjusting, by the controller, the target engine torque when the required torque is equal to or greater than the torque that corresponds to the optimal operating point of the engine.
