PEDAL ASSEMBLY HAVING FORCE SENSING
A pedal assembly includes an upper housing member separated from a lower housing member defining a cavity. The pedal arm is configured to move within the cavity and apply a force to the upper housing member. A pair of fixed magnets are attached to the upper and lower housing. Both of the fixed magnets are orientated with similar polarity facing in the same direction. A moveable magnetic is positioned between the pair of fixed magnets, the moveable magnet positioned with a polarity that is opposite of the pair of fixed magnets. A magnetic sensor is positioned in the housing. When a load is applied to the pedal arm, the pedal arm applies a force to the upper housing member moving the moveable magnet in the housing wherein the magnetic sensor senses movement of the moveable magnet indicative of the amount of depression of the pedal arm.
