11.13.3.3 Parking motor display 

0.45 m

 

According to the operating logic, after two 
current sensors are enabled to work, the front 
left sensor direction indicator lamp displays if 
the front left sensor detects the obstacle, as 
shown in figure, the current distance is 
"0.45m", "logistics trolley" body displays, and 
the buzzer beeps with frequency of 4Hz. 

1.25 m

 

According to the operating logic, after all 
current sensors are enabled to work, the rear 
medium sensor direction indicator lamp 
displays if the rear medium sensor detects the 
obstacle, as shown in figure, the current 
distance is "1.25m", "logistics trolley" body 
displays, and the buzzer beeps with frequency 
of 2Hz. 

 

If reverse radar system detects the obstacle, as 
shown in figure, the "logistics trolley" body 
displays "radar in idle" in Chinese; all sensor 
indicator lamp do not display, which indicates 
that all sensors do not detect the obstacle.

11.13.3.4 Buzzer drive 

The buzzer is integrated in the combination instrument and connected with the parking radar 
control module through a hard wire.

11.13.3.5 Camera 

During reversing, the reversing rearview system is operated; the system takes the picture of the 
rear of the body and converts into the standard video signal. The video signal is transmitted to a 
vehicle-mounted non-core navigation end through the body harness, the vehicle-mounted non-core 
navigation end is automatically switched into the reversing picture after detecting the reversing 
information (a rearview system is in the highest priority during reversing). The driver judges the 
road condition and obstacles behind the body through observing the reversing picture on the 
non-core navigation, thereby improving reversing safety.
