Sensor Installation

1.Vertical installation positionThe radar center is 0.6m-1.3m abovethe ground

2. Horizontal installation position:

3.Assembly and adjustment of the bracket

The installation bracket consists of three parts: lower bracket, middle bracket, and upper bracket.

The lower bracket is used to secure the bracket to the vehicle body

The middle bracket is used to adjust the vertical angle of the radar

(adjustment range ± 10°).
The upper bracket is used to adjust the horizontal angle of the radar

(adiust ment range ±10 °).
When installing, first fix the lower bracket in a suitable position on the vehicle body,.ensuring that it is within the adjustment range of the bracket. lt can adjust the horizontal and vertical angles of the radar to meet the installation requirements.

And then again fix the middle bracket to the lower bracket, the upper bracket to the middle bracket, and finally fix the radar onto the upper bracket.

4.installation and calibration of radar horizontal angle

When installing the radar, the horizontal installation angle should be calibrated toensure that the angle between the normal of the radar surface and the centralaxis of the vehicle body is less than 1 °, and the deviation between the radar andthe central axis of the vehicle body should be less than 20cm. During the calibration process, the display will indicate the degree of deviation of the current radar installation.

The calibration steps are as follows:

a. Move the vehicle to an open area and ensure that there are no obstacles within arange of 20 meters * 10 meters in front of the radar.

b. Place an installation auxiliary line parallel to the centerline of the vehicle body starting from the center of the radar.

C. Place a corner reflector (with a side length of 15cm) at a distance of 12.5 meters from the radar when installing the auxiliary line. The height of the corner reflector should be consistent with the installation height of the radar.

d. After powering on the system, press and hold the setting button for 4.5-6 seconds to enter the calibration preparation interface "CA0". After releasing the setting button press and hold the setting button again to enter "CA1". lf there is no action within 3 seconds,the calibration interface will be entered.

e. Adjust the adjustment bolts of the radar mounting bracket until the color bar on the display shows green (within the acceptable range).f. After the adjustment is completed, restart the system and enter normal working mode.

System function

1.System self-test

When the key is turned to ON, the system starts to make self-diagnosis, and remind driver of the system status by audible and visible warning

2.Basic functions:
2.1 System startup conditions:
a.Turn the ignition switch to ON.

b.GPS signal valid

c.Vehicle speed greater than 20km/h

2.2 Distance monitoring function When the system detects that the vehicle is too close to the vehicle in front during driving, the system will provide an audible and visual alarm to remind the driver to keep the distance:

Users can adjust the sensitivity of the system's distance alarm by setting the PET sensitivity settings on the interface:a.When set to PO, when PET is less than 1.0s, a close proximity warning will be triggered.
b.When set to P1, when PET is less than 1.5 seconds, a close proximity warning will be triggered.

c.When set to P2, when PET is less than 2.0s, a cose proximity warning will be triggered.When the conditions are met, a close proximity warning will be triggered (the color bar is qreen and PET time is displayed, and the buzzer does not sound):

When the distance time (PET) between this vehicle and the vehicle in front isfurther reduced and one of the following conditions is met:a. When the vehicle speed is less than 55km/h, PET is less than 0.70sb. When the vehicle speed is less than 120km/h and greater than 55km/h, PET isess than 0.85sc. When the vehicle speed is greater than 120km/h, PET is less than 1.0s The close proximity reinforcement alarm (with a red bar displaying PET time and a buzzer sounding once every 1 second) will be triggered to remind the driver to maintain the distance.

2.3 Collision warning function

When there is a potential collision risk between this vehicle and the previous vehicle during driving, the system will provide sound through the display.The light alarm reminds the driver to pay attention to braking to avoid collisions.Users can adjust the sensitivity of the collision warning function by setting the TTC sensitivity setting on the interface.

a.When set to Co0

When the vehicle speed is less than 55km/h, the TTC is less than 2.2 seconds.When the vehicle speed is less than 120km/h and greater than 55km/h, the TTC is less than 2.4 seconds.
When the vehicle speed is greater than 120km/h, the TTC is less than 2.7 seconds

b. When set to Co1

When the vehicle speed is less than 55km/h, the TTC is less than 2.5 seconds.When the vehicle speed is less than 120km/h and greater than 55km/h, the TTC is less than 2.7 seconds.When the vehicle speed is greater than 120km/h, the TTC is less than 3.0 seconds.

c. When set to Co2

When the vehicle speed is less than 55km/h, the TTC is less than 2.8 seconds.

When the vehicle speed is less than 120km/h and greater than 55km/h, the TTC is less
than 3.0 seconds.When the vehicle speed is greater than 120km/h, the TTC is less than 3.3 seconds.

When the conditions are met, a collision warning will be triggered (the color bar will bered and flashing, displaying "- pP _", and the buzzer will sound three consecutive times) to remind the driver to pay attention to braking.

When the system detects that the user has brake action, the system will suppress the collision alarm.

3.0 System usage restrictions

Due to the working principle of the system or external working environment, the system has the following working limitations:

a. When the GPS signal is poor, the system may experience issues such asmal function, false alarms, and missed alarms.

b. When the radar is covered with dirt, the system may experience false alarms or missed alarms
c. When the current obstacle is stationary or the vehicle speed is too low, the system may not be able to alarm.
d. When the vehicle is driving on a bend, it may fail to alarm or the alarm maynot be timely.
