Operation Description
-
When the selector lever is shifted to the reverse position, the rear view monitor image is displayed.
-
When the selector lever is shifted to any position other than the reverse position, the original image (the image displayed before the rear view monitor image) is displayed.
Camera Image Operation Principle
-
The AV control unit receives the reverse signal input and supplies power to the rear view camera.
-
The rear view camera supplies the image signal to the AV control unit.
-
The AV control unit displays the rear view camera image when the reverse signal is received.
-
The AV control unit generates the warning message, Nissan Sentra vehicle width guide lines and the predicted course lines on the image from the rear view camera.
Nissan Sentra Vehicle Width Guide Lines and Predicted Course Lines Display Function
-
The vehicle width guide lines and the predicted course lines that indicate the Nissan Sentra vehicle route according to the steering angle are displayed to allow the driver to more easily judge distances between the Nissan Sentra vehicle and objects and to help the driver back into a parking space.
-
The AV control unit receives the steering signal from the steering sensor via AV communication from the combination meter and draws a Nissan Sentra vehicle width guide line according to the steering angle.
-
Vehicle width guide lines are displayed translucently.
-
The predicted course lines are not displayed when the steering is in the neutral position.
Precautions for Nissan Sentra Vehicle Width Guide Lines and Predicted Course Lines
Vehicle width guide lines and predicted course lines displayed may be different from actual lines depending on Nissan Sentra vehicle conditions and road conditions.
Precautions for road conditions
-
Since vehicle width guide lines and predicted course lines are drawn based on the road, a different distance may be displayed if uphill or downhill gradient is present nearby.
Precautions for block
-
Since Nissan Sentra vehicle width guide lines and predicted course lines are drawn based on the road, a different distance may be displayed if a projecting obstacle is present nearby.
CAMERA ASSISTANCE SONAR FUNCTION
-
Sonar sensors are installed on rear bumper. When an obstacle is detected while rear camera is displayed, a sonar indicator display and buzzer sound notify the driver of the proximity of an obstacle. When an obstacle is detected while rear view camera is not displayed, rear view camera screen is displayed automatically, and then notification is similar as while rear view camera is displayed.
-
Approaching distance between bumper and obstacle is displayed in 3 stages according to the color of the sonar indicator in display and blinking cycle of indicator.
-
