Motors
(Sliding, tilt)

Driver side control unit operates the sliding motor when the operating
conditions are satisfied and requests the operations of tilt motor to
automatic drive positioner control unit via UART communication. The
automatic drive positioner operates each motor.

Sensors
(Sliding, tilt)

—

Each sensor monitors the operating positions of seat and steering,
and then stops the operation of each motor when each part reaches
the recorded address.

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000003312356

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
