switch —
Driver seat control unit receives the signals of ignition switch signal
and front door switch from BCM via CAN communication.
2 — Motors (sliding, tilt) Driver seat control unit operates the sliding motor when the operating
conditions are satisfied. Driver seat control unit then requests the op-
eration of the tilt motor to the automatic drive positioner control unit
via UART communication. The automatic drive positioner control unit
operates the motor for a constant amount.
Sensors (sliding, tilt) — Sensors monitor the operating positions of seat and steering wheel
and then stops the operation of each motor when each part reaches
the recorded address.
