ABSTRACT:
A multiplex system for a vehicle includes a controller and at least two remote stations. The remote stations receive input signals indicative of commanded motor operation, and they generate output signals which command power seat motor operation. In order to store a desired seat position, the controller first commands the motors to the home position and then automatically times periods of motor operation for each of the motors as the motors are manually controlled to move the power seat to a selected position. These timed periods of motor activation are then stored as motor activation times. When it is desired to return the seat to the stored position, the controller operates automatically to move the motors to the respective home positions and then automatically to generate motor control signals to drive each of the motors for a time corresponding to the respective motor activation times.
