Power Seat (Driver's Seat)

SYSTEM OUTLINE

1. MANUAL OPERATION

- SLIDE, RECLINING, FRONT VERTICAL, LIFTER, CUSHION, HEAD REST CONTROL
The power seat control SW operation controls the driver seat ECU to operate each power seat motor. This enables the driver to adjust the seat back-and-forth sliding position, the reclining position of the seatback, the height of the front edge of the seat cushion, the height of the seat cushion and seatback, the depth of the seat cushion and the upright position of the headrest at his or her will.

- LUMBAR SUPPORT CONTROL
Operating the lumber support control SW put each of the power seat motor (Driver's seat lumber support upper side control, lower side control) in operation and 2 torsion bars (Upper and lower) individually move continuously. This enables the driver to adjust the seatback touch at his or her will.

2. INTERLOCKING HEADREST SYSTEM
The seat back-and-forth sliding position from the power seat position sensor (Driver seat slide control) and the upright position of the headrest from the power seat motor and sensor (Driver's seat headrest control) are sent as signals to the driver seat ECU. By these signals the driver seat ECU detects the position of them. When the driver's seat is slid forward, the driver seat ECU puts the power seat motor (Driver's seat head rest control) in operation to move the headrest to the appropriate position suitable for the changed seat position. Although the headrest position can be adjusted at will and cleared, the driver seat ECU detects that the driver is different when the sliding position is moved for more than 15 mm. As a result of that, the headrest will be moved into the position which suitable for the changed seat position.

3. DRIVING POSITION MEMORY FUNCTION
Each position sensor in the seat detects the number of rotations of the relevant motor (Seat movement amount) and inputs it to the ECU. This makes it possible to store and recall the seat position by operating the position memory SW. The driving seat position is stored and recalled through communication control of the J/B ECU and door ECU etc.
