NAVIGATION SYSTEM SYSTEM DESCRIPTION


  1. NAVIGATION SYSTEM OUTLINE


    1. 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)

      B004FLNE04
      Operation Description
      Vehicle Position Calculation The navigation ECU calculates the current vehicle position (direction and current position) using the direction deviation signal from the gyro sensor and driving distance signal from the vehicle speed sensor and creates the driving route.
      Map Display Processing The navigation ECU processes the vehicle position data, vehicle driving track and map data from the internal memory.
      Map Matching The map data from the internal memory is compared to the vehicle position and driving track data. Then, the vehicle position is matched with the nearest road.
      GPS Correction The vehicle position is matched to the position measured by the GPS. Then, the GPS measurement position data is compared with the vehicle position and driving track data. If the position is very different, the GPS measurement position is used.
      Distance Correction The vehicle speed signal includes the error caused by tire wear and slippage between the tires and road surface. Distance correction is performed to account for this. The radio receiver assembly automatically offsets the signal to make up for the difference between it and the distance data of the map. The offset is automatically updated.

      Tech Tips

      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.

    2. Autonomous navigation

      This method determines the relative vehicle position based on the driving track determined by the gyro sensor located in the navigation ECU and the vehicle speed signal.


      1. Gyro sensor

        Used to calculate the direction by detecting angular velocity. It is located in the navigation ECU.

      2. Vehicle speed signal

        Used to calculate the vehicle driving distance.

    3. 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.

      B004EZYE01
      *1 Current longitude/latitude/altitude is determined using the signal arrival time from four satellites.
      Number of Satellites Measurement Description
      2 or less Measurement is impossible Vehicle position cannot be obtained because the number of satellites is not enough.
      3 2-dimensional measurement is possible Vehicle position is obtained based on the current longitude and latitude. (This is less precise than 3-dimensional measurement.)
      4 3-dimensional measurement is possible Vehicle position is obtained based on the current longitude, latitude and altitude.

    4. 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 internal memory and the vehicle position is set onto the most appropriate road.

      Note


      • CD-Rs, CD-RWs, DVD-Rs (DVD-Recordable) and DVD-RWs (DVD-ReWritable) may not be played depending on the recording conditions or characteristics of the discs, or due to damage, dirt or deterioration caused by leaving the discs in the cabin for a long time.

      • Unfinalized CD-Rs, CD-RWs, DVD-Rs (DVD-Recordable) and DVD-RWs (DVD-ReWritable) cannot be played.

      • CD-Rs, CD-RWs, DVD-Rs (DVD-Recordable) and DVD-RWs (DVD-ReWritable) are more easily affected by a hot and humid environment than discs used for normal audio CDs. For this reason, some CD-Rs, CD-RWs, DVD-Rs (DVD-Recordable) and DVD-RWs (DVD-ReWritable) may not be played.

      • If there are fingerprints or scratches on a disc, the disc may not be played or may skip.

      • Some CD-Rs, CD-RWs, DVD-Rs (DVD-Recordable) and DVD-RWs (DVD-ReWritable) may deteriorate if they are left in the cabin for a long time.

      • Keep CD-Rs, CD-RWs, DVD-Rs (DVD-Recordable) and DVD-RWs (DVD-ReWritable) in an opaque case.

      • DualDiscs that mate DVD recorded material on one side with CD digital audio material on the other cannot be played.

      • Keep discs away from dirt. Be careful not to damage discs or leave fingerprints on them.

      • Hold discs by the outer edge and center hole with the label side up.

      • Leaving a 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.

      • If a disc has adhesive tape, stickers, disc labels or any traces of such labels attached, the disc may not be ejected or player malfunctions may result.

      • Keep discs away from direct sunlight. (Exposure to direct sunlight may cause deformation of a 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.

      • Use only 4.7 in. (12 cm) discs.

      • Do not use 3 in. (8 cm) discs either with or without adaptors.

      • SECAM color television standard discs cannot be played.

      Tech Tips


      • When it is cold or raining, if the windows fog up, mist and condensation may form in the player. In such cases, a disc may skip or stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player.

      • The disc may skip if the player experiences strong vibrations when the vehicle is driven on rough roads or similar uneven surfaces.

  8. RADIO DESCRIPTION


    1. Radio frequency band


      1. Radio broadcasts use the radio frequency bands shown in the table below.

        B004FGUE08

    2. Service area


      1. B004E0QC06
        *a FM (Stereo)
        *b FM (Monaural)
        *c AM

        The service areas of AM and FM broadcasts are vastly different. Sometimes an AM broadcast can be received very clearly but an FM stereo broadcast cannot. FM stereo has the smallest service area, and is prone to pick up static and other types of interference such as noise.

    3. Radio reception problems

      Tech Tips

      In addition to static, other problems such as "phasing", "multipath" and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself.


      1. B004EZSC06
        *a Phasing
        *b Ionosphere

        Phasing

        AM broadcasts are susceptible to electrical interference and another kind of interference called phasing. Occurring only at night, phasing is the interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off the ionosphere and the other signal is received directly from the transmitter.

      2. B004F93C06
        *a Multipath

        Multipath

        Multipath is a type of interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off buildings or mountains and the other signal is received directly from the transmitter.

      3. B004E6FC05
        *a Fade Out

        Fade out

        Fade out is caused by objects (buildings, mountains and other large obstructions) that deflect part of a signal, resulting in a weaker signal when the object is between the transmitter and vehicle. High frequency radio waves, such as FM broadcasts, are easily deflected by obstructions. Low frequency radio waves, such as AM broadcasts, are less likely to be deflected.

    4. Noise problem

      Technicians must have a clear understanding about each customer's noise complaint. Use the following table to diagnose noise problems.

      Radio Frequency Noise Occurrence Condition Presumable Cause
      AM Noise occurs in a specific area Foreign noise
      Noise occurs when listening to an intermittent broadcast An identical program transmitted from multiple towers can cause noise where the signals overlap
      Noise occurs only at night Signal phasing
      FM Noise occurs while driving in a specific area Multipath resulting from a change in FM frequency

  9. VEHICLE CUSTOMIZATION OUTLINE


    1. Customization of functions can also be performed on the multi-display assembly screen. Refer to the Owner's Manual for further information on customizable items for the navigation system.

      Tech Tips
