Abstract
A method for controlling an air control valve in a diesel hybrid vehicle includes an engine stop detection step for detecting whether a diesel engine is stopped and a vehicle speed is less than a predetermined speed, a first noise and vibration blockade step for controlling a throttle valve to be closed when the diesel engine is stopped and the vehicle speed is less than the predetermined speed, and a first throttle valve control step for closing and then opening again the throttle valve for a predetermined time.
Claims14
A method for controlling an air control valve in a diesel hybrid vehicle, comprising:
- an engine stop detection step for detecting, by a controller, whether a diesel engine is stopped and a vehicle speed is less than a predetermined speed;
- a first noise and vibration blockade step for controlling, by the controller, a throttle valve to be closed when the diesel engine is stopped and the vehicle speed is less than the predetermined speed;
- and
- a first throttle valve control step for closing and then opening again the throttle valve for a predetermined time.
A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:
- program instructions that detect, by the controller, whether a diesel engine is stopped and a vehicle speed is less than a predetermined speed;
- program instructions that control, by the controller, a throttle valve to be closed when the diesel engine is stopped and the vehicle speed is less than the predetermined speed;
- and
- program instructions that close and then open again the throttle valve for a predetermined time.
