System Description

DESCRIPTION

• The AV control unit controls navigation function while GPS tuner has built-in map data, GYRO (angle speed

sensor), on the HDD (Hard Disk Drive).

• The AV control unit inputs operation signal with communication signal, through display (touch panel) and

multifunction switch and steering switch.

• Guide sound is output to front speaker through BOSE amp. from AV control unit when operating navigation

system.

• A vehicle position is calculated with the GYRO (angle speed sensor), vehicle sensor, signal from GPS satel-

lite and map data stored on HDD (Hard Disk Drive), and transmits the map image signal (RGB image, RGB
area, RGB image synchronizing) to the front display unit.

POSITION DETECTION PRINCIPLE

The navigation system periodically calculates the current vehicle
position according to the following three types of signals.
• Travel distance of the vehicle as determined by the vehicle speed

sensor

• Vehicle turning angle determined by the gyroscope (angular speed

sensor)

• The travel direction of the vehicle determined by the GPS antenna

(GPS information)

The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data, which is stored in the HDD
(Hard Disk Drive) (map-matching), and indicated on the screen with
a current location mark. More accurate data is used by comparing
position detection results from GPS to the map-matching.
The current position is calculated by detecting the travel distance
from the previous calculation point, and its direction change.
• Travel distance

The travel distance is generated from the vehicle speed sensor
input signal. The automatic distance correction function is adopted
for preventing a miss-detection of the travel distance because of
tire wear etc.

• Travel direction

The gyroscope (angular velocity sensor) and GPS antenna (GPS
information) generate the change of the travel direction. Both have
advantages and disadvantages as per the following descriptions.

< FUNCTION DIAGNOSIS >

[BOSE AUDIO WITH NAVIGATION]

Input signals are prioritized in each situation. However, this order of priority may change in accordance with
more detailed travel conditions so that the travel direction is detected more accurately.

MAP-MATCHING

Map-matching repositions the vehicle on the road map when a new
location is judged to be more accurate. This is done by comparing
the current vehicle position (calculated by the normal position detec-
tion method) from the map data stored in the HDD (Hard Disk Drive).

There is a possibility that the vehicle position may not be corrected the when vehicle is driven over a certain
distance or time in which GPS information is hard to receive. Manually correct the current location mark on the
screen.
• Map-matching detects, prepares, and prioritizes several alternative

routes in addition to the road detected as currently being driven on.
Therefore, due to errors in the distance and/or direction, an incor-
rect road may be prioritized, and the current location mark may be
repositioned to the incorrect road.
If two roads are running in parallel, they are of the same priority.
Therefore, the current location mark may appear on either of them
alternately, depending on maneuvering of the steering wheel and
configuration of the road, etc.

• Map-matching does not function correctly when the road on which

the vehicle is driving is new, etc. and not recorded in the map data.
In addition map-matching does not function correctly when the
road pattern stored in the map data and the actual road pattern are
different due to repair, etc.
Therefore, the map-matching function detects other roads as a
currently driving road if the road is not in the map, and displays the
current location mark on it. Later, the current location mark may be
repositioned to the road if the correct road is detected.

• Effective range for comparing the vehicle position and travel direc-

tion calculated by the distance and direction with the road data is
limited. Therefore, correction by map-matching is not possible
when there is an excessive gap between the real-time vehicle position and the position on the map.

[BOSE AUDIO WITH NAVIGATION]

NAVIGATION SYSTEM

GPS (Global Positioning System) is developed for and is controlled
by the US Department of Defense. The system utilizes GPS satel-
lites (NAVSTAR), transmitting out radio waves while flying on an orbit
around the earth at an altitude of approximately 21,000 km (13,049
mile).
The receiver calculates the travel position in three dimensions (lati-
tude/longitude/altitude) according to the time lag of the radio waves
that four or more GPS satellites transmit (three-dimensional position-
ing). The GPS receiver calculates the travel position in two dimen-
sions (latitude/longitude) with the previous altitude data if the GPS
receiver receives only three radio waves (two-dimensional position-
ing). GPS position correction is not performed while the vehicle is
stopped.

Accuracy of GPS will deteriorate under the following conditions:
• In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes.
• The position of GPS satellite affects GPS detection precision. The position detection may not be precisely

performed.

• The position detection is not performed if GPS receiver does not receive radio waves from GPS satellites.

(Inside a tunnel, parking in a building, under an elevated highway etc.) GPS receiver may not receive radio
waves from GPS satellites if any object is placed on the GPS antenna.

NOTE:
• The detection result has an error of approximately 10 m (32.81 ft) even with a high-precision three dimen-

sional positioning.

• There may be cases when the accuracy is lowered and radio waves are stopped intentionally because the

GPS satellite signal is controlled by the US trace control center.

System Description

CAMERA IMAGE OPERATION PRINCIPLE

• Power is supplied to rear view camera from camera control unit and outputs camera image signal to camera

control unit when selector lever is set to the “R” position and the reverse signal on camera control unit is
input.

• Camera control unit synthesizes guide lines and possible route lines with camera image signal from rear

view camera, and transmits camera image signal to the front display unit. In this case, since the reverse sig-
nal is also input to AV control unit, the AV control unit recognizes that the selector lever is in the “R” position,
and it switches communication signal between AV control unit and front display unit, and image that is dis-
played on the front display unit by RGB image signal with rear view monitor image. In addition, possible
route lines are controlled by original sensor signal from steering angle sensor.

• The AV control unit determines whether rear view camera is equipped or not, based on the presence of cam-

era connection recognition signal. It switches to rear view monitor image at the time of reverse signal input
when it is equipped.

• Warning message under the rear view monitor display is described by AV control unit.
• AV control unit is connected in communication with camera control unit and front display unit, and it controls

operation of rear view monitor system.
