Abstract
A seat adjusting system having a motor assembly with an integrated sensor and control electronics assembly for adjusting a vehicle seat. The integrated electronics assembly performs electronic memory seat module functions. The integrated electronics assembly includes a multiplex link for communicating data between the integrated sensor and control electronics assembly and an external switch. The integrated electronics assembly further includes motor control relays positioned between the motors of the motor assembly for controlling the motors to adjust the seat. The integrated electronics assembly also includes seat position sensors for monitoring the position of the seat. In contrast to typical seat adjusting systems having an external electronic memory seat module, the seat adjusting system needs only a minimal set of wires connecting the seat adjusting system to an external switch as the integrated electronics assembly performs electronic memory seat module functions.
