Cub B122-036 User manual

77GHz millimeter wave radar sensor
for vehicle advanced turn assist system
User Manual
Product Model: B122-036

Radar Function Instruction
Due to the large vehicles exist blind spots, it is difficult to observe
pedestrians and vehicles entering the blind spot of the inner wheel difference.
Ｗhen cars turn may cause traffic accidents in frequent. The inner wheel
difference is the difference between the turning radius of the inner front
wheel and the turning radius of the inner rear wheel when the vehicle turns.
Because of the inner wheel difference, if you only focus on passing front
wheels and neglect the difference between the inner wheels during driving, it
may cause the road or colliding with other objects.
To avoid this problem could install a set of radars outside of the car. It could
detect blind spot and provide alerts reminding drivers to pay attention
ensuring safety of passengers and passers-by.
Warning System Instruction
The driver assistance system include:
The millimeter wave radar
The warning indicator
Install Instruction
When the millimeter wave radar is installed on the electric bus, in order to
ensure functional detection and warning system working normally, please
follow below instructions：
1. When the surface of radar is covered by dirt, sandstone, waterdrop, or
snow, it may cause the malfunction; consequently, please make sure to
sustain the cleanness of the radar and its surrounding area anytime.
2. The radar and its surrounding area are not able to withstand severe
impact; it may cause the system abnormality or malfunction. Whenever
the radar is getting a severe impact, please make sure to go to the
maintenance depot for inspections.
3. No alteration for non-original accessories (e.g. spraying paint, baking
paint, and metal parts, etc.) is allowed around the surrounding area of
radar; it may cause the radar abnormality or malfunction.
4. Avoid the surrounding area of radar gets covered by objects or walls; it
may cause the trail obstacles detection malfunction or reduced its
functionality.

Security Alert
Under some circumstances, turn assist system may not able to detect the
vehicles. The alert may not be functional under the following situations;
therefore, please drive carefully and stay safe.
•Interruption by the equivalent frequency of the signal from airports,
exercises, and military areas nearby may cause the radar malfunction.
•High speed vehicles enter into the blind zone may not vehicles that
passing by in close succession or closely following may not provide an
alert.
•Vehicles that passing by in close succession or closely following may
not provide an alert.
•When a vehicle comes from behind a corner, the angle of the blind area
of the vehicle body is close to the adjacent lane or the vehicle behind; it
may provide a false alert for the vehicle behind.
•Under the narrow bends, bridge piers, or arched road situations, the
system may not be able to detect incoming vehicles in real-time since
the angle between the vehicle and other vehicles is not in the blind zone.
•When entering a curve or turning, the radar may warn vehicles in the
next lane (due to the rotation of the radar with the angle of the car body).
•Under bushes or construction fences are not ordinary road situations;
radar may launch false alarms.
False Alarm
Under the following circumstance or similar conditions, the system may
launch a warning, even though there is no vehicle appear in the blind zone; it
is a temporary false alarm normally; the false alarms may be launched in the
following situations:
•Wall
•Traffic light pole
•Bushes
•Construction fence
•Continuous uphill and downhill road
•Narrow curves or turning road
•Guiding guardrail or road guardrail
