METHOD FOR INITIALIZING INCREMENT POSITION SENSOR

摘要

An increment sensor assembly inquires an microcontroller as to the last known increment when a vehicle is started. The last known increment data is used to rotate the sensor backward to reach a lower mechanical stop position or forward to reach an upper mechanical stop position. A timer tracks the sensor to ensure that one of the known stop positions is reached within a predetermined time period or performs a system check to determine what error has occurred. Once the sensor reaches one of the known stop positions an increment counter is reset and the sensor assembly begins normal operation.
