The sensor lens points in the vehicle driving direction, the connector either down to the road or up. The outline dimensions of the sensor are shown in the following drawing: Issue Date 30.01.03 Dep.: AE-DA/ELR Name: Hildebrandt Print-Date: 13.01.04 Path: \\lrnt11\acc$\Dokumentenablage in Arbeit & Page:7 von 26 offen\Produktspezifikationen.s\TKUs\K60059_8_TKI_ambience conditions ACC2 mechanics.doc © All rights held by ROBERT BOSCH GMBH, including applications for patents and property rights and the right of disposal, such as to reproduce or pass on to third parties Technical Customer Information Ambience Conditions and Mechanics ACC Distance Control Radar 2nd Generation 0 265 K60 059 Ideally the sensor is to be integrated into the front-end without a cover in front of its lens. If the sensor is to be installed behind a cover or a radome, special care must be taken in selecting the cover-material, cover shape (or design) and position of the cover relatively to the sensor. Water droplets and snow sticking onto the cover surface might cause additional attenuation that leads to a restricted performance or availability of ACC. For the uncovered build-in configuration the lens design of the ACC-SCU is chosen to minimise these effects. Water droplets can be blown off by the driving wind and sticking snow can be heated off by the integrated lens heating. The following table lists the basic demands to the integration of the sensor into a front-end of the car: Installation height above ground (roadway) Horizontal offset relative to the vehicle longitudinal axis 1 Horizontal angle relative to the vehicle longitudinal axis 1 Vertical tilt relative to the vehicle longitudinal axis 1 (dependent on pitch when car is fully loaded or while braking) Clearance of parts (out of metal or even plastic) in front of the sensor can be described by a cone directly in front of the lens with the following angles horizontal vertical The cone that represents the radar beam in shown in figure 1 Clearance to other vehicle parts: (sensor-movement during adjustment: ± 3° vertical and horizontal and additional space for the bracket behind the SCU is considered) in lateral direction in front of the lens behind the sensor (space for clip and bracket) Permissible attenuation caused by cover (bumper, radome) in front of the lens ; two-way (radar) loss The constraints for the cover are: - homogeneous material has to be favourized - non perpendicular orientated relatively to sensor radar axis - favoured materials : see following material list The material in front of the radar should not degrade the antenna parameters • Beamwidth error • Sidelobe change • Peak boresight error In case of radome heating the orientation of wire structures has to be checked Wire diameter is limited to max. 0.25mm Issue Date 30.01.03 Dep.: AE-DA/ELR Print-Date: 13.01.04 Path: \\lrnt11\acc$\Dokumentenablage in Arbeit & min. 300 mm max. 1000 mm max. 500 mm 0° Proposal: adjusting area at sensor ± 3° ± 14° ± 7° each side 10 mm 15 mm 30 mm max . 1 dB Minimise material thickness due to dielectric loss • max. 1% • max. 1 dB • max. 0.1° linear 45° from upper left to lower right as seen in Name: Hildebrandt Page:8 von 26 offen\Produktspezifikationen.s\TKUs\K60059_8_TKI_ambience conditions ACC2 mechanics.doc © All rights held by ROBERT BOSCH GMBH, including applications for patents and property rights and the right of disposal, such as to reproduce or pass on to third parties Technical Customer Information Ambience Conditions and Mechanics ACC Distance Control Radar 2nd Generation In case of shaped radome / bumper the radius of the material is limited In case of non-homogeneous material the air gap between the materials is limited In case of painting carbon based primer is not allowed 0 265 K60 059 driving direction > 25 mm < 0.05mm relative to the ACC SCU; central axis of the lens the full adjustment range is only available at 0° vertical tilt angle results from horizontal beam width (±8°) of the radar beam plus adjustment area (±3°) plus safety margin (±3°).

The bracket is used to attach the sensor to the vehicle. The points where the bracket is attached to the vehicle must be selected carefully to ensure a very stable mounting of the sensor 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 guiding the 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 the customer. Mounting conditions max torque for clip (locking in the bracket) max pressing force (sensor to clip holes min dismantling force (sensor out of clips) min. 2 fixing points at the vehicle no relative movement between the fixing points at the vehicle long-term stability between the fixing points and relative to the vehicle longitudinal axis < 2.5 Nm (max. 3.0 Nm allowed) < 170 N per screw > 70 N per screw The sensor bracket also enables horizontal and vertical adjustment of the ACC SCU radar beam 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 external adjustment fixture, like an optical mirror. No external high frequency measurement equipment is needed.

The “bracket only” tests will be carried out with an ACC-SCU- weight dummy, these tests are always passive tests. Qualification tests are intended to anticipate artificial ageing to simulate long term behaviour of the devices under test. Unless otherwise stated, the tolerances in the temperatures are ± 2 °C and all laboratory tests are performed under the following conditions: • • • • • • upper temperature (Tmax) lower temperature (Tmin) room temperature relative humidity test power operation mode + 85 °C ± 2 °C - 40 °C ± 2 °C + 23 °C ± 5 °C. 45 to 75 % 14 V ± 0,2 V 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 related foreign 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 2 years after SOP.

Additional tests or changed parameters may be necessary because of specific SCU requirements. The electronic design of the device, the location and wiring of the SCU in the car may cause the necessity of additional tests. All tests are to be carried out within an certified EMC test laboratory at an air humidity between 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 identical to production vehicles, become available only at a very late date, so we must refer to the bench tests described below for internal release of the project. Nevertheless it is necessary to test the performance of the system in the vehicle. If the SCU passes the bench tests, but fails the vehicle tests, then further investigations are necessary. To find an acceptable solution the responsible sensor development department will work together with the customer. The final release can only be made in a vehicle 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 components Further customer specific tests in addition to this test sequence have to be discussed and fixed in detail together with Bosch and might be charged separately.
