A Compact Electronic-Throttle-Control Actuator with a Throttle-Position Sensor Integrated Plastic Cover 2002-01-0861

A potentiometer-type throttle-position sensor, wiring, a connector, and a cover for the throttle drive mechanism are integrated in order to reduce the size of an electronic-throttle-control actuator. The throttle-position sensor inside the integrated cover showed a large signal deviation when the environmental temperature changed. This output deviation was caused by the temperature expansion of the plastic material of the integrated cover. With the aim of decreasing the output deviation, we analyzed the temperature sensitivity of the throttle-position-sensor output in order to find optimum location for arc-shaped resistor track, and we increased the rigidity of the plastic gear-cover in order to decrease the effect of the temperature expansion.
