Memory Positioning Systems: Description and Operation

System Outline

This system provides the automatic tilt and telescopic mechanisms using the motor drive and ECU control, allowing variable steering movement in the back and forth, and vertical directions. This makes it possible to set the steering to the desired steering position and move the steering to a position where the driver can easily get off the vehicle, allowing easier seating. Additionally, by linking the power seat and remote control mirror, an optimal driving position corresponding to the driver's needs can be stored into the memory.

1. Auto Return Operation
When the ignition key is inserted into the key cylinder, the signal is input to the tilt and telescopic ECU through communication control of the J/B ECU and door ECU etc. This activates the ECU to automatically return the steering to the position set before the ignition key has been removed.

2. Auto Away Operation
When the ignition key is turned from ON to OFF and removed from the key cylinder, the signal is input to the tilt and telescopic ECU through communication control of the J/B ECU and door ECU etc. This activates the ECU to automatically move the steering to the top tilt step position and maximum telescopic retract position.

3. Manual Operation
If the TILT and TELESCOPIC SW is operated when the ignition key is inserted in the ignition key cylinder, the signal is sent to the tilt and telescopic ECU by the multiplex communication. As a result of that, the tilt and telescopic ECU controls the motor to adjust the telescopic position or the tilt position at will.

4. Driving Position Memory Function
The pulse signals detected by the tilt and telescopic sensors are input to the ECU. This makes it possible to store and recall the desired driving position through communication control of the power seat ECU and door ECU etc.
