Abstract
A method for controlling a start time of an engine in a hybrid vehicle includes: generating, by a controller, an engine start command before executing start control of the engine in response to an acceleration signal output from an acceleration pedal sensor; determining, by the controller, a gradient of a road on which the hybrid vehicle travels; controlling, by the controller, a hybrid starter-generator to operate by controlling the engine to start depending on the engine start command when it is determined that the gradient of the road is present; and controlling, by the controller, electric power of the hybrid starter-generator to charge a battery which provides electric power to a motor. The controller controls an engine clutch so that the motor is not engaged with the engine.
