2 System operational description
The Blind Spot Monitoring (BSM) system is designed to assist the driver by monitoring
blind spots on both sides of the vehicle to the rear in certain situations such as when
changing lanes on roads and freeways
The BSM system monitors the detection areas on both sides of the vehicle to the rear when
the vehicle speed is about 32 km/h (20 mph) or more. and notifies the driver ot'velticles in
the detection area by illuminating the BSM warning light
Ifthe turn signal lever is operated in the direction the BSM warning light is illuminated, the
system warns the driver ofthe vehicle in the detection area with a beep sound.

VBSM Warning Light/Beep
Equipped on the lefi and right door
mirrors,
This warning light illuminates for a few
seconds when the ignition is switched
ON.
Ifthe BSM system detects a vehicle in the
detection area while the vehicle is driven
at a speed ofabout 32 kmfh 120 mph) or
more. the BSM waming light illuminates
on the side ofthe vehicle where the rear

3 Sensor operational description
Figure 1: Cross section of BSDTX sensor
The sensor is shown in Figure 1. Two different RADAR beams are used to detect targets.
3.1 BSDTX sensor surveillance zone
To cover the blind spot area beside the vehicle a two beam approach is used, as shown in Figure 2. A BROAD
beam with a maximum range of ca. 8m and a smaller beam, that is tilted by 33° to the boresight direction of the
broad beam is used. The smaller TILT beam has a maximum detection range of ca. 15 m. Despite the higher
antenna gain of the TILT beam the maximum e.i. p. emitted power is identical with the BROAD beam. This is
realized by changing the input power at the antenna ports accordingly.

4 Radiation Hazard
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 uW). The
active emitting antenna surface is 72 cm2; therefore the radiated power density in front of the BSM device is 0.55
uW/cmz. This value is far below the legal human exposure protection limit of 1 le cm2(MPE) in Europe and
US.

5.2 BSDTX radar specific emission limits
The following limits regarding intentionai RF radiation apply for the two radar lranemitlers (TILT and BROAD)
0 Peak power Ilmlt = -14 dBm EIRP for 10 MHz resolution bandwidth
(corresponding to a worst-case peak power of OdBm in 50 MHz) and
- RMS average power limit = -41,3 dBm/M Hz EIRP
(EIRP means: emitted Isotropic radiated power). The FCC regulations describe measurement rules which shaii
be used for equipment authorization. According to these rules a resolution bandwidth of 10 MHz is selected for
the peak power measurements.
