FAIL-SAFE CONTROL METHOD FOR ENGINE CLUTCH ACTUATOR AND APPARATUS THEREOF

摘要

A fail-safe control method and apparatus for an engine clutch actuator includes determining whether a driving mode of a hybrid vehicle is an electric vehicle (EV) mode. An oil pressure in a cylinder of the engine clutch actuator is measured when the driving mode of the hybrid vehicle is the EV mode. The oil pressure value in the cylinder is compared with a previously stored average pressure value. A motor of the engine clutch actuator rotates to decrease the oil pressure value in the cylinder t when the oil pressure value in the cylinder is greater than the previously stored average pressure value. An engine clutch is connected to an internal combustion engine as the oil pressure value in the cylinder decreases.

1. A fail-safe control apparatus for an engine clutch actuator comprising:
a pressure sensor to measure a pressure value in a cylinder of the engine clutch actuator; a local controller to determine whether a driving mode of a hybrid vehicle should be in either an electric vehicle (EV) mode or a hybrid vehicle mode (HEV) by comparing the pressure value measured by the pressure sensor with an average pressure value of the cylinder in the EV mode; and a motor rotated according to a command of the local controller in order to control the pressure value of the cylinder to connect or release between an engine clutch and an internal combustion engine.
