Abstract
Official abstract text for this publication.
An adjustable spoiler for a vehicle includes a pressure sensor sensing a pressure applied to an upper side of a spoiler and generating a current signal in proportion to the pressure. An electronic control unit (ECU) is configured to control an angle of a spoiler according to the current signal from the pressure sensor. The spoiler is mounted on the upper side of a vehicle body.
First claim
Opening claim text (preview).
What is claimed is: 1. A adjustable spoiler for a vehicle, comprising: a pressure sensor sensing a pressure applied to an upper side of the adjustable spoiler and generating a current signal in proportion to the pressure; and an electronic control unit (ECU) configured to control an angle of the adjustable spoiler according to the current signal, wherein the adjustable spoiler is mounted on the upper side of a vehicle body. 2. The adjustable spoiler of claim 1 , wherein the pressure sensor includes a plurality of piezoelectric elements arranged on the upper side of the adjustable spoiler, and each of the plurality of piezoelectric elements generates a current in proportion to the pressure while the vehicle runs. 3. The adjustable spoiler of claim 1 , wherein when the current signal is input from the pressure sensor, the ECU controls the angle of the adjustable spoiler by operating an actuator which adjusts the angle of the adjustable spoiler according to the current signal. 4. The adjustable spoiler of claim 1 , wherein when the current signal is input from the pressure sensor, the ECU compares a value of the current signal with a standard lift value in real time, and when the current signal value is greater than the standard lift value, the ECU increases the angle of the adjustable spoiler. 5. The adjustable spoiler of claim 1 , wherein when the current signal is input from the pressure sensor, the ECU compares a value of the current signal with a standard lift value in real time, and when the current signal value is smaller than the standard lift value, the ECU decreases the angle of the adjustable spoiler. 6. A method for controlling an adjustable spoiler for a vehicle, comprising: sensing, by a pressure sensor, a pressure applied on an upper side of the adjustable spoiler and generating a current signal in proportion to the pressure; comparing, by an ECU, the current signal with a standard lift value; and adjusting, by the ECU, an angle of the adjustable spoiler according to the current signal. 7. The method of claim 6 , further comprising, after the step of comparing: increasing the angle when the current signal has a value greater than the standard lift value. 8. The method of claim 6 , further comprising: decreasing the angle when the current signal has a value smaller than the standard lift value.
