Automatic Drive Positioner: Overview Infiniti FX35 I

SYSTEM DESCRIPTION

1. The system automatically moves the driver seat to facilitate entry/exit to/from the vehicle. The automatic drive positioner control unit can also store the optimum driving positions (driver seat, pedal position and door mirror position) for 2 people. If the driver is changes, one-touch operation allows changing to the other driving position.
2. The settings (ON/OFF) of the automatic sliding seat (Entry/Exiting operation) at entry/exit can be changed as desired, using the display unit in the center of the instrument panel. The set content is transmitted by CAN communication, from display unit (without NAVI) or display control unit (with NAVI) to driver seat control unit.
3. Using CONSULT-II, the seat slide amount at entry/exit setting can be changed.

Manual Operation

The driving position [seat position, steering wheel position (tilt, telescopic) and door mirror position] can be adjusted with the power seat switch or ADP steering switch or door mirror remote control switch.

Note. The seat can be manually operated with the ignition switch OFF. The door mirrors can be manually operated with the ignition switch turned ACC or ON.

Scheme 28

Note. Disconnecting the battery erases the stored memory. After connecting the battery, insert the key into the ignition cylinder and turn the driver door switch ON (open)-->OFF (close)-->ON (open), the Entry/ Exiting operation becomes possible. After exiting operation is carried out, return operation can be operated.

Note. During automatic operation, if the ignition switch is turned ON-->START, the automatic operation is suspended. When the ignition switch returns to ON, it resumes.

Scheme 29

1. Store the 2 driving positions and shifts to the stored driving position with the memory switch.
2. Key fob interlock function is set simultaneously with setting driving position memory. It can set driving position to memory position.

Note. If another key fob inter lock function setting is performed by same key, newly registered setting is valid. If new memory string is performed to memory switch that already set key fob interlock function, key fob interlock function setting is reset. If key does not set previously, key fob interlock function cannot set.

Memory Switch Operation

Selecting the memory

Scheme 30

Note. The driver's seat position and steering adjustment functions (see PRIORITY FUNCTION table) operate simultaneously in the order of priority.

PRIORITY FUNCTION

Entry Operation

When the seat are on the exiting positions, the following operation moves the seat to the previous position before the exiting operation.

Scheme 31

Exiting Operation

At exit, the seat is automatically moved to the exiting position.

Scheme 32

Scheme 33

1. Perform memory operation, exiting operation and entry operation by pressing key fob unlock button.

Note. If steering wheel operation is cancelled, the system performs seat and mirror operation only. If Entry/Exiting operation is cancelled, the system performs steering wheel operation and mirror operation only. If ignition switch turns ON in the middle of memory operation, the system does not perform exiting operation after memory operation. If ignition switch turns ON in the middle of exiting operation, entry operation starts at that time.

Fail-Safe Mode

When any manual and automatic operations are not performed, if any motor operations of seats or tilt of steering are detected for approx. 0.1 sec. or more, status is judged "Output Malfunction". Motor operation will be suspended automatically, and all automatic operations will be ineffective (in this case, the motor will not operate manually).

CAN COMMUNICATION SYSTEM DESCRIPTION

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, 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.
