SYSTEM DESCRIPTION

1. GENERAL

(a) When the vehicle is driven at 10 km/h (6 mph) or less, the ultrasonic sensors on the front and rear bumper detect obstacles near the vehicle. Based on signals from the steering angle sensor, the ultrasonic sensors perform a collision/avoidance judgment. Then they communicate the information through the display and navigation module display, multi-information display, and buzzer.

2. FUNCTION OF COMPONENTS





3. OPERATION EXPLANATION

This system has a steering sensing mode and a normal clearance sonar mode.

(a) Steering sensing mode

(1) The ultrasonic sensors on the front bumper estimate the distance to an obstacle, and the angle of the obstacle in relation to the vehicle. When the sensor receives information about the obstacle and signals from the steering angle sensor, and the obstacle is within the sensor's detection area, an approximate collision/avoidance judgment is made (to be used as an estimate to increase the possibility of avoiding a collision), and the information is communicated through the displays and buzzer.

* The displays mentioned above refer to the multi-information display and the display and navigation module display.
* Refer to "OPERATION CHECK" for the sensor detection range Operation Check.

(b) Normal clearance sonar mode

(1) All obstacles in the sensor detection range are detected regardless of the information from the steering angle sensor.





(2) Normal clearance sonar mode detection range
