Title:
PEDAL POSITION SENSOR USING BIPOLAR TAPERED MAGNETS
Document Type and Number:
WIPO Patent Application WO2002038930
Kind Code:
A3
Abstract:
A pedal and sensor assembly for mounting to a vehicle. The assembly has a pedal arm having a first end and a second end. A magnetic field generator is connected to the second end to generate a variable magnetic field as the pedal moves. A housing is attached to the vehicle and has the second end and the magnetic field generator contained therein. A magnetic field sensor is located adjacent to the magnetic field generator and detects the variable magnetic field such that as the pedal arm rotates the magnetic field sensor generates an electrical signal proportional to the stregth of the variable magnetic field and that is indicate of the position of the pedal arm.
