1. GENERAL
The system then informs the driver of the distance between the sensors and the obstacles as well as their positions by indicating them on the clearance sonar display and by sounding a buzzer.
2. FUNCTIONS OF COMPONENTS
Components |
Function |
Ultrasonic Sensor | Ultrasonic sensor consists of a sensor portion that transmits and receives ultrasonic waves and a pre-amplifier that amplifies the waves. The ultrasonic sensor outputs the ultrasonic transmission and reception signals to the clearance warning ECU. |
Clearance Sonar Main Switch | Turns the clearance sonar system on and off. |
Clearance Warning Buzzer | Emits an intermittent sound to inform the driver that the ECU has detected an obstacle within prescribed ranges. |
Clearance Warning ECU | Judges the approximate distance between the vehicle and the obstacle based on the signals from the ultrasonic sensors and sends the display signal to the clearance sonar indicator and the buzzer signal to the clearance warning buzzer. |
Indicators | Displays the location of the obstacle and the approximate distance between the vehicle and the obstacle. |
Speed Sensor | Detects speed of each wheel and inputs the data into the clearance warning ECU via the combination meter. |
Park / Neutral Position Switch (A/T) | Sends a signal that activates the clearance sonar system when the shift lever is moved to the R position. |
3. OPERATION EXPLANATION
Based on this information, the clearance warning ECU sends signals to the indicator and the clearance warning buzzer. The approximate distance between the vehicle and the obstacle is then indicated, and the buzzer sounds.
