CONSTRUCTION
The non-contact type accelerator pedal sensor assembly uses a Hall IC.
The magnetic yoke that is mounted at the base of the accelerator pedal arm moves around the Hall IC in accordance with the amount of effort that is applied to the accelerator pedal. The Hall IC converts the changes in the magnetic flux that occur at that time into electrical signals, and outputs them in the form of accelerator pedal effort to the ECM.
This accelerator pedal sensor assembly includes 2 Hall ICs and circuits for the main and sub signals. It converts the accelerator pedal depressing angles into electric signals with 2 differing characteristics and outputs them to the ECM.
