Memory Positioning Systems: Description and Operation

AUTOMATIC DRIVE POSITIONER

System Description
- The system automatically moves the driver seat. The automatic drive positioner control unit can also store the optimum driving positions (driver seat) for 2 people. If the driver is changes, one-touch operation allows changing to the other driving position.

MANUAL OPERATION
The driving position [seat position, steering wheel position (tilt, telescopic)] can be adjusted with the power seat switch or ADP steering switch.

NOTE: The seat can be manually operated with the ignition switch OFF.







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 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 table) operate simultaneously in the order of priority.




KEYFOB INTERLOCK OPERATION
- Perform memory operation by pressing keyfob unlock button or driver side door request switch.




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.
