High-resolution electronic throttle position system |
摘要 |
A high-resolution position sensing apparatus for determining the angular position of a throttle plate located in an electronic throttle and controlled by a PCM includes a first throttle position sensor and a second throttle position sensor. The first throttle position sensor is coupled to the throttle plate and generates a first throttle position sensor output signal. The first throttle position sensor output signal is a negative slope signal and is affine to the position of the throttle plate from full closed to full open. The second throttle position sensor is also coupled to the throttle plate and generates a second throttle position sensor output signal. The second throttle position sensor output signal is a positive slope signal and is affine to the position of the throttle plate from full closed to approximately one-half open. Because the second sensor is used over a smaller range it may be used to achieve a higher signal resolution over that smaller range.
