Circuit Description

The memory seat module monitors the locations of the adjustable pedals using position sensors mounted to the brake and accelerator pedal actuators. The position sensors are supplied with a 5-volt reference and ground circuits from the memory seat module. The position sensor signal circuits are referenced from ground within the memory seat module. The signal voltages monitored by the memory seat module range from 0.25-4.75 volts and are determined by the wiper locations on the resistors within the position sensors. The position sensor signal circuit voltage levels are used by the memory seat module to determine the positions of the adjustable pedals when storing or recalling memory position settings. The memory seat module also monitors the locations of both pedal assemblies in order to prevent a step over condition from occurring. During manual or memory operation the position sensor inputs to the memory seat module must remain within 0.6 volts or 31 counts of each other. During a calibration procedure the position sensor inputs must not vary more than 0.3 volts or 23 counts.
