System Description
NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM (for HDD): SYSTEM DESCRIPTION
1. NAVIGATION SYSTEM OUTLINE
(a) Vehicle position tracking methods
It is essential that the navigation system correctly tracks the current vehicle position and displays it on the map. There are 2 methods to track the current vehicle position: autonomous (dead reckoning) and GPS* (satellite) navigation. Both navigation methods are used in conjunction with each other.
*: GPS (Global Positioning System)
HINT
The combination of autonomous and GPS navigation makes it possible to display the vehicle position even when the vehicle is in places where GPS signals cannot be received. When only autonomous navigation is used, however, the mapping accuracy may slightly decrease.
(b) Autonomous navigation
This method determines the relative vehicle position based on the driving track determined by the gyro located in the navigation computer sub-assembly and the vehicle speed signal.
(1) Gyro sensor
Used to calculate the direction by detecting angular velocity. It is located in the navigation computer sub-assembly.
(2) Vehicle speed signal
Used to calculate the vehicle driving distance.
(c) GPS* navigation (Satellite navigation)
This method detects the absolute vehicle position using radio waves from GPS satellites.
*: GPS satellites were launched by the U.S. Department of Defense for military purposes.
(d) Map matching
The current driving route is calculated by autonomous navigation (according to the gyro sensor and vehicle speed signal) and GPS navigation. This information is then compared with possible road shapes from the map data in the hard disk drive and the vehicle position is set onto the most appropriate road.
2. MULTI-DISPLAY OUTLINE
(a) A pop-up type multi-display is built into the center instrument cluster finish panel assembly. Opening, closing and tilt angle adjustments of the multi-display can be performed using the multi-display switch.
3. REMOTE TOUCH OUTLINE
HINT
* The navigation system is remotely controlled using the remote touch switch knob and switches.
* The remote touch is equipped with a feedback force function.
* When the remote touch switch knob is operated, the built-in 2-axis motors are controlled. The motors are used to provide feedback force for the knob according to the pointer operation displayed on the multi-display.
* The feedback force of the remote touch allows the users to select icons easily when operating the navigation system.
(a) Remote Touch Switch Knob Operation
(1) Movement of the pointer on the multi-display screen is synchronized with knob operation.
HINT
* During remote touch switch knob operation, the distance that the knob moves is sent to the navigation computer sub-assembly as operational coordinates. The range of operational coordinates for the lateral and longitudinal axes is between 0 and 255.
* The multi-display also has operational coordinates that range from 0 to 255 for the lateral and longitudinal axes. The navigation computer sub-assembly displays the pointer according to the operational coordinates from the knob.
(b) Remote Touch Switch Knob Feedback Force
(1) The remote touch has 2 built-in motors. These motors control both lateral and longitudinal axes and generate feedback force according to remote touch switch knob operation.
HINT
* There are 3 types of feedback force image areas (Icons, Frames and Others) are provided on the multi-display screen. The feedback force changes depending on the area.
* The navigation computer sub-assembly sends a feedback force request signal to the remote touch according to the pointer location displayed on the multi-display.
* When the remote touch receives the feedback force request signal, the remote touch controls the motors and generates 3 types of feedback force according to the operation direction of the remote touch switch knob.
* The strength of feedback force generated by the remote touch can be adjusted. Refer to the owner's manual for further information.
(2) Icon Area
HINT
* When the pointer comes close to an icon area, force will be provided to pull the pointer toward the center of the icon area.
* Stronger force is provided while driving than while parked.
(3) Frame Area
HINT
Frame areas are provided for the edges of all display screens. When the pointer comes close to the edge of the screen, force will be provided to move the pointer away from the edge of the screen.
(4) Other Area
HINT
* When the pointer is in an area other than one of those specified, resistance will be provided that is proportional to the remote touch switch knob operation speed.
* Stronger resistance is provided on the map screen than on other screens.
4. DVD (DIGITAL VERSATILE DISC) PLAYER OUTLINE (for DVD Changer Models)
(a) The DVD player can only play DVD videos, DVD audio and video CDs that have any of the following marks:
(1) Precaution for use of discs
NOTICE:
* PAL or SECAM color television standard discs cannot be played (only NTSC discs can be played).
* Keep the discs away from dirt. Be careful not to damage the discs or leave fingerprints on them.
* Hold discs by the outer edge and center hole with the label side up.
* Leaving the disc exposed halfway out of the slot for a long time after pressing the disc eject button may cause deformation of the disc, making the disc unusable.
* Do not use odd-shaped discs because these may cause player malfunctions.
* Do not use discs whose recording portion is transparent or translucent because they may not be inserted, ejected or played normally.
* DualDiscs that mate DVD recorded material on one side with CD digital audio material on the other cannot be played.
(b) Cleaning
NOTICE:
Do not use a lens cleaner because it may cause a malfunction in the pickup portion of the player.
(1) If dirt is on the disc surface, wipe it clean with a soft dry cloth such as an eyeglass cleaner for plastic lenses from the inside to the outside in a radial direction.
NOTICE:
* Pressing on the disc by hand or rubbing the disc with a hard cloth may scratch the disc surface.
* Use of solvents such as record spray, antistatic agents, alcohol, benzine, thinners or a chemical cloth may cause damage to the disc, making the disc unusable.
5. "Bluetooth" OUTLINE
(a) "Bluetooth" is a trademark owned by Bluetooth SIG, Inc.
(b) "Bluetooth" is a wireless connection technology that uses the 2.4 GHz frequency band.
HINT
The communication performance of "Bluetooth" may vary depending on obstructions or radio wave conditions between communication devices, electromagnetic radiation, communication device sensitivity or antenna capacity.
(c) Hands-free function
(1) The "Bluetooth" built-in radio receiver assembly and a "Bluetooth" compatible cellular phone*1 can be connected using a "Bluetooth" wireless connection. This enables the use of the hands-free function on the cellular phone even if the phone is in a pocket or bag. For this reason, it is not necessary to use a connector or cable to connect the cellular phone.
*1: Some versions of "Bluetooth" compatible cellular phones may not function.
6. RBDS FUNCTION OUTLINE (BROADCAST IN NORTH AMERICA ONLY)
