3. NOTES FOR REAR TELEVISION CAMERA Notes for the rear television camera assembly The advanced parking guidance system may not function properly if subjected to a severe blow by any hard object. Do not scrub the cover part of the camera (resin made). Scrubbing may scratch the cover and affect the image. Prevent organic solvents, waxes, bond removing solvents or glass coating from adhering to the cover. If such material adheres to the cover, clean it off immediately and wash with water. Exposing the camera to a sudden temperature change may affect proper functioning of the camera. A clear image may not appear if the camera is dirty with snow, mud, etc. In that case, wash it with water and wipe off the lens. Use a detergent to remove dirt if necessary. Images are difficult to discern even in normal conditions if: Noise may occur in the image depending on electrical devices used in the cabin. Noise may occur in the image if the outer mirror switch assembly is operated. Noise may occur in the image if accessories that generate radio waves have been installed. The camera screen is frosted over (the image immediately after turning the power switch on (IG) may be blurred or darker than normal). The camera lens is dirty with snow, mud, etc. A strong beam of light, such as a sunbeam or headlight, hits the camera. It is too dark around the camera (at night etc.). The ambient temperature around the camera is either too high or too low. The vehicle is tilted at a steep angle. The ambience of the camera is too bright. (When a strong light, such as a sunbeam reflected off the vehicle body, hits the camera, the image may be blurred. This is called the "SMEAR" phenomenon, peculiar to the CCD camera.)
4. NOTES FOR ULTRASONIC SENSOR Under the following conditions, the detection function may not function properly: A sensor or the front bumper is not installed in the correct position. A sensor is improperly located due to damage to the front bumper. A sensor is covered with foreign matter, such as mud or snow (detection function returns to normal when the sensor is cleaned). A sensor is frozen (detection function returns to normal when the temperature of the sensor rises). A hand is blocking a sensor. HINT: In very cold weather where a malfunction display appears, the sensor may not be able to detect obstacles. If the sensor has malfunction, the advanced parking guidance system DTC will be output. Refer to «DTC CHECK / CLEAR»(ref-393052-S28442832582011040700000) . If the malfunction display appears, visually check the sensor first. If the sensor is free of foreign matter but the malfunction display remains, the sensor may have a malfunction. The detection range may be affected by the following conditions: HINT: Depending on a shape of a parked vehicle or an obstacle such as a wall or post near the parking space, the detection range may change even though the sensors are operating normally. A sensor or the front bumper is not installed in the correct position. A sensor is improperly located due to damage to the front bumper. A sensor is covered with foreign matter, such as mud or snow. The vehicle is in an excessively hot or excessively cold area. Under the following conditions, a detection error may occur: HINT: Depending on a shape of a parked vehicle or an obstacle such as a wall or post near the parking space, the detection range may change even though the sensors are operating normally. A sensor or the front bumper is not installed in the correct position. A sensor is improperly located due to damage to the front bumper. Driving on a bumpy road, an unpaved road or in tall grass. Ultrasonic waves are received from the horn or parking sonar system of another vehicle, a motorcycle engine, or the air brakes of a large vehicle. It is raining heavily or the sensor is splashed with water. The vehicle is tilted at a steep angle. The vehicle is equipped with a fender pole or a wireless antenna mechanism. A sensor is covered with foreign matter, such as mud or snow. The vehicle is moving forward or backward towards high curbs or objects that are perpendicular to the ground. A sensor is sprayed with high pressure water or steam. The sensors cannot detect the following objects: Thin objects, such as wires and ropes. Materials that absorb ultrasonic waves, such as cotton, snow, etc. Objects with sharp edges. Short objects. Objects that are tall and protrude toward the vehicle above the detection range of the sensors. Other notices: The sensors cannot detect objects directly under the bumper. (A sensor may detect low objects and thin poles, and then lose track of them.) Beware that the detection range of the ultrasonic sensor is limited. In certain conditions, some objects may not be detected. As a result, always make sure to check all around the vehicle when driving or parking. The sensors may not be able to detect obstacles that are too close to the sensor. The sensors may not be able to detect obstacles if the sensors have been dropped or subjected to a strong impact.

1. GENERAL The parking assist ECU uses vehicle condition signals from the spiral with sensor cable sub-assembly, power steering ECU, skid control ECU, power management control ECU, etc. to make calculations and estimates. These results are used to make various guidelines, which are combined together with video from the rear television camera, and output to the navigation receiver assembly. Also, control signals are output to each ECU and the advanced parking guidance system various controls are performed. This system has a rear television camera assembly mounted on the back door to display an image of the area behind the vehicle on the navigation receiver assembly display. The display panel also shows a composite view consisting of the area behind the vehicle and parking guidelines to assist the driver in parking the vehicle by monitoring the area behind the vehicle. This system is equipped with a self-diagnosis system, which is operated on a designated window that appears on the display panel, just as in the navigation system.
2. FUNCTION OF COMPONENTS The parking assist ECU controls the system by using information from the following components. Component Function Rear Television Camera Assembly Mounted on the back door to the transmit an image of the area behind the vehicle to the parking assist ECU. Has a color video camera that uses a Charge Coupled Device (CCD) and a wide-angle lens. Parking Assist ECU Receives vehicle condition signals from various ECUs, makes frame based on calculations, combines the frame with video from the rear television camera, and outputs the video with frame to the navigation receiver assembly. Also, control signals are output to each ECU and the advanced parking guidance system various controls are performed. Navigation Receiver Assembly Receives video signals containing a composite of an image of the area behind the vehicle and the frame signals from the parking assist ECU, and displays them on the display panel. Uses the yaw rate detected by the gyro sensor that is built into the navigation receiver assembly to transmit the movement of the vehicle to the parking assist ECU. Spiral with Sensor Cable Sub-assembly Detects the angle of the steering wheel and sends the resulting signals to the parking assist ECU through CAN communication. ECM Sends the shift position signal to the parking assist ECU through CAN communication. Skid Control ECU Sends stop switch, vehicle speed, driving distance, and other vehicle condition signals to the parking assist ECU. Power Steering ECU Assembly Sends EPS failure, intervention steering, and other related vehicle condition signals to the parking assist ECU. Also, based on advanced parking guidance control signals and steering-related signals, performs steering control. Parking Assist Pre Support Switch Sends the switch operation signal to the parking assist ECU. No. 1 Ultrasonic Sensor Controlled by the parking assist ECU and detects an available parking space. Air Conditioner Amplifier Assembly Sends the outside temperature signal to the parking assist ECU through CAN communication. Rear Height Control Sensor Sub-assembly RH Sends the vehicle height signal to the parking assist ECU.
3. OPERATION EXPLANATION The parking assist ECU receives the camera activation information from the navigation receiver assembly. Then, the parking assist ECU switches the display signal for the navigation receiver assembly from the navigation system to the advanced parking guidance system.
4. PRE SUPPORT FUNCTION Function Description A pre support function is provided to assist the driver with initial positioning of the vehicle when backing-in mode or parallel parking mode operation is used.
