Abstract
An apparatus for determining a failure of an engine clutch is provided. The apparatus includes an engine clutch that is disposed between an engine generating power and a motor and a driving information detector that senses driving information including a shift speed stage, an engine speed, a motor speed, a SOC of a battery, and a vehicle speed. A controller then determines a driving mode of the engine from the detected driving information and determines whether oil leakage of the engine clutch is generated from the driving information and the driving mode.
Claims15
An apparatus for determining a failure of an engine clutch, comprising:
- an engine clutch disposed between an engine generating power and a motor;
- a driving information detector configured to sense driving information including a shift speed stage, an engine speed, a motor speed, a state of charge (SOC) of a battery, and a vehicle speed;
- and a controller configured to determine a driving mode of the engine from the detected driving information and determine whether oil leakage of the engine clutch is generated from the driving information and the driving mode;
- wherein the controller is configured to turn off the engine to be driven in an electric vehicle (EV) mode in response to determining that the oil leakage is generated in the hydraulic pressure line of the engine clutch.
A method for determining a failure of an engine clutch of a hybrid vehicle, comprising:
- sensing, by a driving information detector, driving information including a shift speed stage, an engine speed, a motor speed, and a vehicle speed;
- determining, by a controller, a driving mode of an engine from the detected driving information;
- determining, by the controller, whether oil leakage is generated in a hydraulic pressure line of an engine clutch disposed between an engine and a motor from the driving information and the driving mode;
- and turning off, by the controller, the engine to be driven in an electric vehicle (EV) mode in response to determining that the oil leakage is generated in the hydraulic pressure line of the engine clutch.
A non-transitory computer readable medium containing program instructions executed by a controller for determining a failure of an engine clutch of a hybrid vehicle, the computer readable medium comprising:
- program instructions that control a driving information detector to sense driving information including a shift speed stage, an engine speed, a motor speed, and a vehicle speed;
- program instructions that determine a driving mode of an engine from the detected driving information;
- program instructions that determine whether oil leakage is generated in a hydraulic pressure line of an engine clutch disposed between an engine and a motor from the driving information and the driving mode;
- and program instructions that turn off the engine to be driven in an electric vehicle (EV) mode in response to determining that the oil leakage is generated in the hydraulic pressure line of the engine clutch.
