СИСТЕМА ECD


  1. CONSTRUCTION


    1. The non-contact type accelerator pedal position sensor uses a Hall IC.

    2. The magnetic yoke mounted on the base of the accelerator pedal arm moves around the Hall IC in accordance with the accelerator pedal opening angle. The Hall IC converts the changes in magnetic flux that occur into electrical signals, and outputs them in the form of an accelerator pedal input signal to the ECM.

    3. This accelerator pedal position sensor includes 2 Hall ICs and circuits for the main and sub signals. The sensor converts the accelerator pedal opening angle into voltage signals with 2 differing characteristics and outputs them to the ECM.

    4. On the models with kick-down mode, when the accelerator pedal opening angle is greater than a predetermined amount, the ECM detects a "kick-down mode" from the VPA signal provided by the accelerator pedal position sensor.
