Preface This chapter describes the specifications to install short range SLR radar into bumpers. These specifications shall be complied with to enable the specified characteristics of the sensors as well as the complete system. Due to the various installation situations and applications, a measurement check is required to verify the actual installation implementation. 5.2. SLR Sensor This chapter describes the characteristics relevant to the installation of SLR sensors in the bumper. In addition general specifications are mentioned, which have to be followed for each position to enable sufficient sensor performance. Therefore the following guidelines are to be observed very carefully. See annex for performance measurements. 5.2.1. Dimensions and Weight of the SLR Sensor Figure 1 shows the dimensions of the SLR sensor (C-sample status) and details the mounting of the sensor. Please refer to “Outline 6181175” for detailed drawings. Sensor weight: 190 grams max. Title: Installation Specifications, Radar Sensors Doc. No. E567781 INSTALLATION SPECIFICATION Rev. 000, Page 4 of 14 5.0 SPECIFICATIONS Figure 1 Important note: The two mounting holes are not specified for m ounting the complete sensor. They do not provide the mechanical properties to keep the sensor in place. They shall be used to fix the sensor in a mounting bracket. Mounting tabs are to be fa stened tight to mounting bracket using appropriate fastener. Maximum strength per tab is 270 N. Title: Installation Specifications, Radar Sensors Doc. No. E567781 INSTALLATION SPECIFICATION Rev. 000, Page 5 of 14 5.0 SPECIFICATIONS 5.2 SLR Sensor (cont’d) 5.2.2 Detection Range / Azimuth Angle Measurement Range Figure 2 displays the detection area of the SLR sensor. One should differentiate between the detection area of the sensor and the angle measurement area. The angle measurement area is reduced to ±40° around bore sight whereas the detection area is ±65°. The detection area is related to the 10dB points, this means the area where the signal amplitude is reduced by 10dB compared to bore sight direction. Within the detection area of the antennas there must not be metal parts like screws, mounting brackets, license plate etc. The impact reducing foam material, clips or fascia laminations has to be avoided in that area. Figure 2 Title: Installation Specifications, Radar Sensors Doc. No. E567781 INSTALLATION SPECIFICATION Rev. 000, Page 6 of 14 5.0 SPECIFICATIONS 5.2 SLR Sensor (cont’d) 5.2.3 Detection Angle Elevation Figure 3 shows the detection area of the antennas in elevation. The detection area of ±8 ° is related to the 3dB points, this means the area where the signal amplitude is reduced by 3dB compared to bore sight direction. To avoid close range false objects there must not be metal parts like screws, mounting brackets, license plate etc in an angle of ±30 ° (see figure 3). Impact reducing foam material, clips or fascia laminations must be avoided in this area. Figure 4 shows details of objects keep out zone. Figure 3 Figure 4 Title: Installation Specifications, Radar Sensors Doc. No. E567781 INSTALLATION SPECIFICATION Rev. 000, Page 7 of 14 5.0 SPECIFICATIONS 5.3 Installation Specifications For Individual Sensors 5.3.1 Distance To The Bumper Material The distance of the SLR sensor to the bumper shall be between 5 and 20 mm. If the distance is below 5 mm a significant signal loss occurs. If the distance is larger, error ranges may appear within the close range. Figure 5 5.3.2 Angle with respect to bumper material The angle φ of the sensor with regard to the bumper should be 0 ° , meaning the sensor should be installed parallel to the bumper. If …
