This BSM (blind spot monitoring) device emits intentional electromagnetic radiation in the 24 GHz to
25 GHz frequency range. The total radiated average power over the entire bandwidth is below – 14
dBm (40 µW). The active emitting antenna surface is 72 cm

; therefore the radiated power density in
front of the BSM device is 0.55 µW/cm

1. ( ) (General) (continued)
1.2 BSM ( ) (Outline of the BSM Module) (continued)
BSM module refers to short range radar sensor used to fulfill the function and performance
of BSM system. BSM system will be implemented by installing BSM module on both right and left
hand side behind the rear bumper of the subject vehicle (2pieces in total). The BSM modules
communicate via CAN to obtain input and output of necessary data with vehicle itself and other
systems on the vehicle.
BSM system detects moving vehicles (objects of interest) within the detection zone (blind
spot) to identify the non relevant objects. (stationary objects, moving vehicles outside of detection
zone and road infrastructure)
This system warns the driver by illuminating of an BSM icon installed on right and left rear
view mirror (first level warning) and alarm sound (2
nd
level warning coupled with turn indicator
signal) when an object of interest enters the warning zone and the warning requirement condition
is fulfilled. (Details of the warning is referred in 3.1.2)

This system supports to recognize the objects hardly found just by viewing side and rear
view mirrors.
This is used exclusively for driving support for the driver. The driver must check with eyes
over his/her shoulder to confirm the safety. The BSM system is not intended to substitute the rear
view mirror of the subject vehicle. The system is for supplemental use only. The driver is still
100% responsible for his actions.
Also BSM module is checking the system faults on BSM system all the time, and when any
system fault is detected, it must turn on the BSM warning in HEC and must record the Fault code.
BSM module must perform initial diagnosis when BSM system is started up. (IG1
when OFF => ON)
Additionally, BSM module implements BSM system diagnosis every time system starts
up, and has a function to warn the trouble by BSM warning and record the trouble details
when detecting a trouble.
The detail of trouble record is according 3.5, however it is required at least to record
the necessary data for analyzing when trouble occurs.

2) Blinking
Vehicle IG-ON: Must be this status when "system abnormal" is detected.
This status must not occur at vehicle IG-OFF.
In case the sensor blockage is detected, blinking frequency should be 0.25 Hz
(Repeat 2sec ON / 2sec OFF).
In case the DTC is detected except sensor blockage, blinking frequency should be
1Hz (Repeat 0.5sec ON / 0.5sec OFF).
3) Lighting
Vehicle IG-ON: Must be this status when "system normal" and "operation aborted"
and when "system abnormal" and "operation aborted".
This must not occur at vehicle IG-OFF.

EOL Test Setup (Outline)
After the installation of the BSM modules the vehicle is located in an assembly line with several
objects within the field of view of the sensor.
For a basic functional test of the BSM system objects in the field of view of the sensor, or test
objects placed in the field of view may be used as target.
The test procedure of the sensor comprises the emission and reception of the 24 GHz radiation
separately for the two beams.
The successful detection of objects at a position with a tolerance is a perfect test for the principal
functionality of the sensor and the communication interface to the vehicle.
