ECD SYSTEM


  1. CONSTRUCTION


    1. The non-contact type accelerator pedal sensor assembly 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 amount 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 sensor assembly includes 2 Hall ICs and circuits for the main and sub signals. It converts the accelerator pedal opening angles into electric signals with 2 differing characteristics and outputs them to the ECM.

    4. On models with the cruise control system, when the accelerator pedal opening angle is greater than a predetermined amount, the ECM detects a "kick down mode" request through the VPA signal sent by the accelerator pedal sensor assembly.
