Section VIII Reverse Radar System
I. Overview
Vehicle reverse radar system is a kind of vehicle monitoring system imitating bat detection
principles. By installing several ultrasonic radar probes, receive and send signals, and send
feedback information to controller. According to signal reentrant time, controller can calculate the
distance to the tested barrier, and trigger different sound and indicator warning according to
different distances to remind driver for the distance between the barrier and vehicle, and increase
backup convenience and safety.
1. The warning mode applied by this reverse radar system is instrument cluster display screen
LCD, as shown in Fig. 4-109.
2. Radar detection range: see Fig. 4-110.
The reverse radar distance in LCD applies segment display and is controlled by instrument cluster,
specific distance detection and display as follows:
a. When detection distance S is greater than 1.5m, no light in all 3 sections:
b. When detection distance S greater than 1m and equal or less than 1.5m, light in outermost layer:
(warning: time interval of 1s);
c. When detection distance S is greater than 0.5m and equal and less than 1m, light in 2 outer
layers: (warning: time interval of 0.5s);
d. When detection distance S is less than 0.5m, light in all 3 layers:
warning).
