Hybrid electric vehicle capable of maximizing driving distance in engine clutch failure situation and method of controlling the same
First Claim
1. A method of controlling a hybrid electric vehicle provided with an engine clutch installed between a first motor and an engine, the method comprising:
- in response to a determination that failure of the engine clutch occurs, determining a state of the engine clutch finally obtained before the failure;
in response to a determination that the state of the engine clutch finally obtained before the failure is an open state, driving the first motor alone; and
in response to a determination that the state of the engine clutch finally obtained before the failure is not the open state, starting the engine.

Abstract
A hybrid electric vehicle which may maximize a driving distance in an engine clutch failure situation and a method of controlling the same are disclosed. The method of controlling the hybrid electric vehicle provided with an engine clutch installed between a first motor and an engine includes, in response to a determination that failure of the engine clutch occurs, determining a state of the engine clutch just prior to the failure, in response to a determination that the state of the engine clutch just prior to the failure is an open state, driving the first motor alone, and in response to a determination that the state of the engine clutch just prior to the failure is not the open state, starting the engine.

11. A hybrid electric vehicle comprising:
-
a first controller configured to control a first motor; a second controller configured to control an engine; a third controller configured to control an engine clutch disposed between the first motor and the engine; and a fourth controller configured to; determine a state of the engine clutch finally obtained before the failure, if failure of the engine clutch is detected by the third control unit, in response to a determination that the state of the engine clutch finally obtained before the failure is an open state, control the first controller to drive the first motor alone, and in response to a determination that the state of the engine clutch finally obtained before the failure is not the open state, control the second controller to start the engine. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
