AUTOMATIC DRIVE POSITIONER SYSTEM

AUTOMATIC DRIVE POSITIONER SYSTEM : System Description

INFOID:0000000003312327

OUTLINE

The system automatically moves the driver seat, steering column and door mirror position by the driver seat
control unit and the automatic drive positioner control unit. The driver seat control unit corresponds with the
automatic drive positioner control unit by UART communication.

NOTE:
The lumbar support system and the side support system are controlled independently with no link to the auto-
matic drive positioner system.

Function Description

Manual function

The driving position (seat, steering column and door mirror position) can be adjusted
by using the power seat switch, tilt & telescopic switch or door mirror remote control
switch.

Memory function

The seat, steering column and door mirror move to the stored driving position by
pressing seat memory switch (1 or 2).

Entry/Exit assist function

Exit

On exit, the seat moves backward and the steering column moves upward.

Entry

On entry, the seat and steering column returns from exiting position to the previous
driving position.

Intelligent Key interlock function

Perform memory operation, exiting operation and entry operation by Intelligent Key
unlock operation or driver side door request switch unlock operation.

OUTLINE

The driver seat control unit can store the optimum driving positions (seat, steering column and door mirror
position) for 2 people. If the front seat position is changed, one-touch (pressing desired memory switch) oper-
ation allows changing to the other driving position.
NOTE:
Further information for the memory storage procedure. Refer to

3.

Press desired memory switch.

4.

Driver seat, steering and door mirror will move to the memorized position.

OPERATION CONDITION

Satisfy all of the following items. The memory function is not performed if these items are not satisfied.

However, the memory operation can be performed for 45 seconds after opening the driver door (driver door switch OFF

Motors
(Seat, Steering,

Driver seat control unit operates each motor of seat when it recogniz-
es the memory switch pressed for 0.5 second or more and requests
each motor operation to automatic drive positioner control unit via
UART communication. The automatic drive positioner control unit op-
erates each motor.

Driver seat control unit requests the flashing of memory indicator
while either of the motors is operating. The driver seat control unit il-
luminates the memory indicator.

Sensors
(Seat, steering col-
umn, door mirror)

—

Driver seat control unit judges the operating seat position with each
seat sensor input. The positions of the steering column and outside
mirror are monitored with each sensor signal. Driver seat control unit
stops the operation of each motor when each part reaches the record-
ed address.

Memory switch Indica-
tor

Driver seat control unit requests the illumination of memory indicator
after all motors stop. The driver seat control unit illuminates the mem-
