360°VIEW MONITOR SYSTEM
id151000004300
Outline
• The 360° view monitor system is technology created from Mazda's safety philosophy stated as the reduction of accident occurrence risk itself, and which is particular to the recognition support function.
• The 360° view monitor system displays the images shot by the four cameras (front camera, side cameras (LH, RH), rear mount camera) equipped to the vehicle at the viewpoints from the front/back, left/right, and above the vehicle on the center display, and supports the driver in recognizing risks in the driver's blind spot areas under the following conditions.
-
― When entering T-intersections
― When making left/right turns
― When accelerating vehicle after parking or stopping vehicle
― When vehicles pass each other on narrow lane roads
― When parallel parking
― When reversing
• The 360°view monitor system has 5 screen display patterns for the top view/front view, top view/rear view, front wide view, rear wide view, and side view. Switching of each screen display can be performed by pressing the commander switch or touching the camera switching icon.
Functions
• The 360° view monitor system consists of the following functions.
Top view
-
• The top view assists the driver in checking the area around the vehicle while the vehicle is moving forward or reversing, and combines video signals from the four cameras (front camera, side cameras (LH, RH), rear mount camera) equipped to the vehicle and displays the viewpoint of the area around the vehicle from the top of the vehicle on the center display.
• The top view displays on the right side of the screen when the screen of the front view or rear view is being displayed.
Front view
-
• The front view assists the driver in checking the vehicle front while the vehicle is moving forward, and displays images shot by the front camera equipped to the vehicle on the center display.
• The front view displays on the left side of the screen when the screen of the top view is being displayed.
Front wide view
-
• The front wide view assists the driver in checking the vehicle front and the sides of the vehicle while the vehicle is moving forward, and displays images shot by the front camera equipped to the vehicle on the center display.
• The front wide view displays wide angle images from the front view on the center display.
Side view
-
• The side view assists the driver in checking the left/right/front side of the vehicle while the vehicle is moving forward, and displays images shot by the two cameras (side cameras (LH, RH)) equipped to the vehicle on the center display.
Rear view
-
• The rear view assists the driver in checking the vehicle rear while the vehicle is reversing, and displays images shot by the rear mount camera equipped to the vehicle on the center display.
• The rear view displays on the left side of the screen when the screen of the top view is being displayed.
Rear wide view
-
• The rear wide view assists the driver in checking the sides of the vehicle and the vehicle rear while the vehicle is reversing, and displays images shot by the rear mount camera equipped to the vehicle on the center display.
• The rear wide view displays wide angle images from the rear view on the center display.
Screen display switching function
-
• When the commander switch is pressed or the camera switching icon is touched while the top view/front view, top view/rear view, front wide view, rear wide view, or side view is displayed, the 360° view monitor control module switches the displayed image.
When top view/front view, front wide view, side view is displayed
When top view/rear view, rear wide view is displayed
Dynamic range correction function
-
• For the 360° view monitor control module, visibility in dark areas has been improved by performing correction to the dark area when light and dark areas are mixed. The dynamic range correction function performs correction to the dark area when the light switch is OFF or at AUTO*1.
*1 :Headlights/TNS/panel light turns off
Color brightness correction function
-
• The 360° view monitor control module maintains constant color brightness by performing correction if there are differences in the color brightness of each camera on the top view display.
-
Note
-
• Because images displayed in the top view screen are processed from each camera, the top view display may be displayed in the following ways.
-
― If an image containing an object with a color is picked up in the wide range by any of the cameras, the whole screen may be affected and it may display in that color.
― The entire screen may appear bright or dark depending on the illumination level around any of the cameras.
Parking sensor system
-
• The parking sensor system uses ultrasonic sensors to detect obstructions around the vehicle, and notifies the driver of the approximate distance from the vehicle to the surrounding obstruction using sound and an obstruction detection indication. For details on the parking sensor system, refer to the [PARKING SENSOR SYSTEM].(See PARKING SENSOR SYSTEM.)
Rear Cross Traffic Alert (RCTA)
-
• The Rear Cross Traffic Alert (RCTA) uses ultrasonic sensors to detect vehicles approaching from the rear of the vehicle, and assists the driver in checking the rear of the vehicle while reversing by flashing the Blind Spot Monitoring (BSM) warning lights and activating the warning sound. For details on the Rear Cross Traffic Alert (RCTA), refer to the [BLIND SPOT MONITORING (BSM) SYSTEM].(See BLIND SPOT MONITORING (BSM) SYSTEM.)
Malfunction indication function
-
• The 360° view monitor control module displays the system malfunction condition on the center display.
-
Note
-
• If each camera has a malfunction, the image taken from the applicable camera is displayed on the center display in black.

Operation
Top view/front view, front wide view, side view display operation
-
Operation condition
-
• When all of the following conditions are met, the top view/front view, front wide view, side view can be displayed.
-
― Ignition is switched ON (engine off or on)
― Selector lever is in a position other than R(ATX)
― Shift lever is in a position other than reverse or neutral (MTX)
1. When a 360° view monitor switch ON signal (1) is received with the operation conditions met, the 360° view monitor control module receives an image signal (2) from the front camera/side cameras (LH, RH)/rear mount camera.
2. The received image signal processes an image, and then the 360° view monitor control module sends (3) it to the CMU.
3. The CMU converts the received video signal to a LVDS signal and sends (4) the LVDS signal to the center display.
4. The center display indicates (5) the images at the area around the vehicle based on the LVDS signal received from the CMU.
5. When any of the following conditions is met, the 360° view monitor control module switches the images indicated on the center display to non-display.
-
• Parking brake ON signal is received (parking brake is applied)(MTX)
• Selector lever is shifted to P position(ATX)
• When 360° view monitor switch is pressed while vehicle speed is less than approx. 15km/h
-
― Approx. 270 s have elapsed since 360° view monitor switch was pressed
― Vehicle speed is approx. 15 km/h or more
• When 360° view monitor switch is pressed while vehicle speed is approx. 15 km/h or more
-
― Vehicle speed is approx. 15 km/h or more after approx. 8 s have elapsed since 360° view monitor switch was pressed
― Two-hundred sixty-two s have elapsed from the point when the vehicle speed was less than 15 km/h after 8 s have elapsed since pressing the 360° view monitor switch.
― Vehicle speed is less than approx. 15 km/h after approx. 8 s have elapsed since pressing the 360° view monitor switch, however the vehicle speed is 15 km/h or more after that.
