Water droplets and snow sticking onto the cover surface might causeadditional attenuation that leads to a restricted performance or availability of ACC. For theuncovered build-in configuration the lens design of the ACC-SCU is chosen to minimisethese effects. Water droplets can be blown off by the driving wind and sticking snow canbe heated off by the integrated lens heating.The following table lists the basic demands to the integration of the sensor into a front-endof the car:Installation height above ground (roadway) 1min. 300 mmmax. 1000 mmHorizontal offset relative to the vehicle longitudinal axis 1max. 500 mmHorizontal angle relative to the vehicle longitudinal axis 10°Vertical tilt relative to the vehicle longitudinal axis 1(dependent on pitch when car is fully loaded or while braking)Proposal: adjustingarea at sensor ± 3° 2Clearance of parts (out of metal or even plastic) in front of thesensor can be described by a cone directly in front of the lens withthe following angleshorizontalverticalThe cone that represents the radar beam in shown in figure 1± 14° 3± 7° 4Clearance to other vehicle parts:(sensor-movement during adjustment: ± 3° vertical and horizontaland additional space for the bracket behind the SCU is considered)in lateral directionin front of the lensbehind the sensor (space for clip and bracket)each side 10 mm15 mm30 mmPermissible attenuation caused by cover (bumper, radome) in frontof the lens ; two-way (radar) lossmax . 1 dBThe constraints for the cover are:- homogeneous material has to be favourized- non perpendicular orientated relatively to sensor radar axis- favoured materials : see following material listMinimise materialthickness due todielectric lossThe material in front of the radar should not degrade the antennaparameters• Beamwidth error• Sidelobe change• Peak boresight error• max. 1%• max. 1 dB• max. 0.1°In case of radome heating the orientation of wire structures has tobe checkedWire diameter is limited to max. 0.25mmlinear 45°from upper left tolower right as seen in

The points where the bracket isattached to the vehicle must be selected carefully to ensure a very stable mounting of thesensor relatively to the vehicle longitudinal axis.The three clips are used to fix the sensor in the bracket. First each clip is locked by 90°rotation (clockwise). The sensor is fitted to the bracket by pressing the sensor with guidingthe clip hole (see figure 2 above).Please note that the bracket needs some space in the near surrounding of the sensor.The overall dimensions of the sensor with bracket have to be discussed together with thecustomer.Mounting conditions min. 2 fixing points at the vehicleno relative movement between the fixing points at thevehiclelong-term stability between the fixing points and relativeto the vehicle longitudinal axismax torque for clip (lockingin the bracket)< 2.5 Nm (max. 3.0 Nm allowed)max pressing force (sensorto clip holes< 170 N per screwmin dismantling force(sensor out of clips)> 70 N per screwThe sensor bracket also enables horizontal and vertical adjustment of the ACC SCU radarbeam to the vehicle longitudinal axis see figure below.In our solution this is done with self-tapping adjustment screws in plastic mounts.The adjustment is done after attaching the sensor to the vehicle, using an externaladjustment fixture, like an optical mirror.

The “bracket only” tests will be carriedout with an ACC-SCU- weight dummy, these tests are always passive tests.Qualification tests are intended to anticipate artificial ageing to simulate long termbehaviour of the devices under test. Unless otherwise stated, the tolerances in thetemperatures are ± 2 °C and all laboratory tests are performed under the followingconditions:• upper temperature (Tmax) + 85 °C ± 2 °C• lower temperature (Tmin) - 40 °C ± 2 °C• room temperature + 23 °C ± 5 °C.• relative humidity 45 to 75 %• test power 14 V ± 0,2 V• operation mode active / non powered (valid for ACC-SCU)Test criteria:• Electrical function test completed without failures (if test values outside the tolerance,a separate evaluation is necessary).• No electrical or mechanical error function during the tests.• No functionally related mechanical damages after the tests and no functionally relatedforeign substances in the device under test after the kind-of-protection-tests.After the tests the devices will be scraped not earlier than 1 year and not last than 2years after SOP.

Additional tests or changed parameters may be necessary because of specific SCUrequirements. The electronic design of the device, the location and wiring of the SCU inthe car may cause the necessity of additional tests.All tests are to be carried out within an certified EMC test laboratory at an air humiditybetween 45% ± 15% and a room temperature of 23°C ± 5°C unless otherwise stated.In general vehicle tests are in customer’s responsibility. Test vehicles, which are identicalto production vehicles, become available only at a very late date, so we must refer to thebench tests described below for internal release of the project. Nevertheless it isnecessary to test the performance of the system in the vehicle.If the SCU passes the bench tests, but fails the vehicle tests, then further investigationsare necessary. To find an acceptable solution the responsible sensor developmentdepartment will work together with the customer. The final release can only be made in avehicle test.The ACC2 sensor will be approved according the following EMC test sequence:• Radiation Immunity according ISO 11541-2 (12.1995)• Radiated Emission according CISPR 25 Section 2 (11.1995)• Disturbance by other in-vehicle componentsFurther customer specific tests in addition to this test sequence have to be discussed andfixed in detail together with Bosch and might be charged separately.
