Acceleration signal detector |
摘要 |
An acceleration signal detector is provided for detecting an acceleration condition of an engine based on the open-and-close operation of a throttle valve. Switching arrangements associated with the throttle valve are provided for detecting the fully closed condition of the throttle valve and for detecting a partially closed condition of the throttle valve. Signal processing apparatus receives output signals from the switching arrangements, and a change in the output of the means for detecting a partially closed condition subsequent to a change in the output of the means for detecting the fully closed condition is indicative of acceleration. This arrangement eliminates erroneous signals that might otherwise be caused by chattering of switch contacts.
