Abstract
A system of controlling an adjustable spoiler includes an ignition detector configured to detect whether an engine is turned on or off. A vehicle speed detector is configured to detect a vehicle speed. A weight detector is configured to detect a vehicle weight that is changed when the number of passengers or the amount of loaded freight is increased or decreased. A controller is configured to determine variation of the vehicle weight, set an extension reference speed and a retraction reference speed of the adjustable spoiler based on the variation of the vehicle weight, and extend or retract the adjustable spoiler trough an actuator.
Claims15
A system of controlling an adjustable spoiler, comprising:
- an ignition detector configured to detect whether an engine is turned on or off;
- a vehicle speed detector configured to detect a vehicle speed;
- a weight detector configured to detect a vehicle weight that is changed when the number of passengers or the amount of loaded freight is increased or decreased;
- and
- a controller configured to determine variation of the vehicle weight, set an extension reference speed and a retraction reference speed of the adjustable spoiler based on the variation of the vehicle weight, and extend or retract the adjustable spoiler trough an actuator.
A method of controlling an adjustable spoiler, comprising steps of:
- determining variation of a vehicle weight, which is changed when the number of passengers or the amount of loaded freight is increased or decreased, when an engine is turned on;
- setting an extension reference speed and a retraction reference speed based on the variation of the vehicle weight;
- determining whether a vehicle speed is greater than the extension reference speed;
- and
- extending the adjustable spoiler through an actuator when the vehicle speed is greater than the extension reference speed.
