Title: PARK ASSIST / MONITORING: PARKING ASSIST MONITOR SYSTEM: SYSTEM DESCRIPTION; 2018 - 2020 MY Camry [06/2017 - 10/2020]

SYSTEM DESCRIPTION

GENERAL

(a) This system has a rear television camera assembly mounted on the luggage compartment door to display an image of the area behind the vehicle on the multi-display. The multi-display also shows a composite view consisting of the area behind the vehicle and parking guide lines to assist the driver in parking the vehicle by monitoring the area behind the vehicle.

When the rear camera detection function of the rear television camera assembly detects a pedestrian within the detection area when reversing, a buzzer sounds and an icon is displayed on the multi-display to warn the driver.

(b) This system consists of the following components:

(1) Rear Television camera assembly

(2) Radio and display receiver assembly

(3) Steering sensor

(4) ECM

(5) Main body ECU (multiplex network body ECU)

(6) Skid control ECU

(7) Blind spot monitor sensor

(8) RCTA buzzer (blind spot monitor buzzer)

(9) BKUP LP relay

(10) Clearance warning ECU assembly*

  • *: w/ Intelligent Clearance Sonar System

(c) This system is equipped with a self-diagnosis system, which is operated on a designated window that appears on the multi-display.

FUNCTION OF COMPONENTS

(a) The rear television camera assembly controls the system by using information from the following components.

Item

Function

Rear Television Camera Assembly
  • Mounted on the luggage compartment door to transmit a composite image of the area behind the vehicle and guide lines calculated based on signals received from each ECU, to the radio and display receiver assembly.
  • Has a color video camera that uses a Complementary Metal Oxide Semiconductor (CMOS) and wide-angle lens.
  • Stops displaying the guide lines when an open signal is received for the luggage compartment door.
  • Performs overall control of the system by receiving signals from the sensor and ECUs.
  • Transmits a camera detection buzzer request signal to the blind spot monitor sensor via CAN communication.

Radio and Display Receiver Assembly
  • Receives video signals which contain a composite image of the area behind the vehicle taken with the rear television camera assembly and guide lines calculated based on signals received from each ECU.
  • Performs control of the system by receiving the reverse signal from the BKUP LP relay.
  • Transmits a setting information signal to the rear television camera assembly via CAN communication.
  • Receives diagnostic mode video signals from the rear television camera assembly.
  • Displays "You can not calibrate the camera when the door is open. Please close the door." on the back camera position setting screen when the luggage compartment door is open.

Steering Sensor

Detects the angle of the steering wheel and transmits the resulting signals to the rear television camera assembly via CAN communication.

ECM
  • Transmits the vehicle information signal to the rear television camera assembly via CAN communication.
  • Transmits the reverse signal to the rear television camera assembly via CAN communication.

Skid Control ECU

Transmits the vehicle speed signal to the rear television camera assembly via CAN communication.

Main Body ECU (Multiplex Network Body ECU)

Transmits the luggage compartment door courtesy switch signal and vehicle information signal to the rear television camera assembly via CAN communication.

Blind Spot Monitor Sensor
  • Transmits the RCTA information signal to the rear television camera assembly via CAN communication.
  • Sounds the RCTA buzzer (blind spot monitor buzzer) when the rear camera detection function is operating.

RCTA Buzzer (Blind Spot Monitor Buzzer)

Sounds based on a signal from the blind spot monitor sensor.

BKUP LP Relay

Transmits the reverse signal to the radio and display receiver assembly.

Clearance Warning ECU Assembly*

Transmits the sonar information signal to the rear television camera assembly via CAN communication.
  • *: w/ Intelligent Clearance Sonar System

OPERATION EXPLANATION

(a) Operation description of the park assist monitor system

(1) The radio and display receiver assembly receives the reverse signal when the engine switch is on (IG) and the shift lever is moved to R. After receiving the reverse signal, the multi-display switches to the parking assist monitor system.

(b) Operation description of the rear camera detection function

(1) Operation conditions:

  • The engine switch on (IG).
  • The shift lever is in R.
