CONSTRUCTION
This non-contact type accelerator pedal sensor assembly uses a Hall IC, which is mounted on the accelerator pedal arm.
A magnetic yoke is mounted at the base of the accelerator pedal arm. This yoke rotates 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 into electrical signals, and outputs them in the form of accelerator pedal position signals to the ECM.
This accelerator pedal sensor assembly includes 2 Hall ICs and circuits for the main and sub signals. The accelerator pedal sensor assembly converts the accelerator pedal depressed angles into electric signals with 2 differing characteristics and outputs them to the ECM.
