Memory Positioning Systems: Description and Operation

AUTOMATIC DRIVE POSITIONER

System Description
- 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, steering wheel position (tilt, telescopic) and door mirror position) for 2 people. If the driver is changes, one-touch operation allows changing to the other driving position.
- 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 control unit to driver seat control unit.
- Using CONSULT-II, the seat slide and steering wheel 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.







AUTOMATIC OPERATION




MEMORY STORING AND KEYFOB INTERLOCK STORING
- Store the 2 driving positions and shifts to the stored driving position with the memory switch.
- Keyfob interlock function is set simultaneously with setting driving position memory. It can set driving position to memory position.

NOTE:
- If another keyfob interlock function setting is performed by same key, newly registered setting is valid.
- If new memory string is performed to memory switch that already set keyfob interlock function, keyfob interlock function setting is reset.
- If key does not set previously, keyfob interlock function cannot set.







MEMORY SWITCH OPERATION
Selecting the memory

NOTE: The driver's seat position and steering adjustment functions (see the following table) operate simultaneously in the order of priority.




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




EXITING OPERATION
At exit, the seat are automatically moved to the exiting position.




KEYFOB INTERLOCK OPERATION
- Perform memory operation, exiting operation and entry operation by pressing keyfob 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).

CANCEL OF FAIL-SAFE MODE
- The mode is cancelled when the selector lever is shifted to P position from any other position.

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.
