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.

A method for controlling a start time of an engine in a hybrid vehicle, comprising:
- 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,
- wherein the controller controls an engine clutch so that the motor is not engaged with the engine.
A device for controlling a start time of an engine in a hybrid vehicle, comprising:
- an acceleration pedal sensor which detects operation of an accelerator pedal;
- an acceleration sensor which detects acceleration of the hybrid vehicle;
- and
- a controller which generates an engine start command before executing start control of the engine in response to an acceleration signal output from the acceleration pedal sensor and determines a gradient of a road on which the hybrid vehicle travels based on acceleration provided by the acceleration sensor,
- wherein the controller controls 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, the controller controls electric power of the hybrid starter-generator to charge a battery which provides electric power to a motor, and the controller controls an engine clutch so that the motor is not engaged with the engine.
A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:
- program instructions that generate an engine start command before executing start control of the engine in response to an acceleration signal output from an acceleration pedal sensor;
- program instructions that determine a gradient of a road on which the hybrid vehicle travels;
- program instructions that control 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
- program instructions that control electric power of the hybrid starter-generator to charge a battery which provides electric power to a motor,
- wherein an engine clutch is controlled so that the motor is not engaged with the engine.
