The accelerator pedal position sensor is installed on the upper end of the accelerator pedal assembly. The sensor detects the accelerator position and sends a signal to the hybrid vehicle control ECU. Accelerator pedal position sensor has two sensors. These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the hybrid vehicle control ECU. The sensor 1 signal is used to detect the accelerator pedal position and the sensor 2 signal is used as a confirmation to allow the detection of malfunction in the sensor itself. In addition, these sensors detect how much the accelerator pedal is depressed and feed the voltage signals to the hybrid vehicle control ECU. The hybrid vehicle control ECU judges the current opening angle of the accelerator pedal from these signals, and sends the engine speed request signal and engine power request signal to the ECM. The ECM controls the throttle control motor based on these signals. Furthermore, the hybrid vehicle control ECU uses these signals for operating motor torque. Idle position of the accelerator pedal is determined by the hybrid vehicle control ECU receiving the signal from the accelerator pedal position sensor. The hybrid vehicle control ECU uses this signal for various engine operation.
