Mounting Requirements Mounting Requirements Overview The installation of the Bendix VORAD VS-400 System is intended to cover a wide range of commercial vehicle applications. This ™ ® publication is intended to be a reference for commercial vehicle installations using the vehicle’s SAE J1939 data link interface. For vehicles without a SAE J1939 data link, some installation procedures may vary for a proper system installation and operation.

The FLR is a Doppler radar that transmits at a 77 GHz frequency. A built-in yaw rate sensor (gyro) provides relative azimuth for lane positioning in turns. The SAE J1939 interface allows the FLR to be installed as a Bendix ™...

Mounting Requirements Requirements The Forward Looking Radar can be mounted on the front of the vehicle, or integrated behind a non-metallic body panel as long as the mounting, alignment, and material requirements are met in the following sections. Field of View Defi nition The Forward Looking Radar (FLR) fi...
Page 15
It is recommended that any material that will be located in the FLR fi eld of view be approved by Bendix Commercial Vehicle Systems prior to use. If the radar has a cover perpendicular to the radar beam, even a very slight vibration of the cover can cause the refl ected radar signal to be seen as a very strong false target at close range.

Mounting Requirements Vibration Specifi cations Mounting mechanisms shall be designed to be compliant with the radar vibration spectrum illustrated below. These vibration constraints are based on radio-frequency considerations in order to be compliant with the radar functional specifi cation. There are no specifi c mechanical requirements along the Y- and Z-axis from a radio-frequency point of view. The mechanical movements measured at the FLR center along the X-axis shall be less than the peak-to-peak displacement shown below.

Mounting Requirements Painting A wide variety of colors and textures can be applied to the Forward Looking Radar housing using commercially available organic paints and conventional application processes. Painting the component may assist with color degradation over time. The following guidelines apply: •...

Mounting Requirements Alignment ▲ WARNING The alignment of the Forward Looking Radar is critical to the correct operation of the Bendix ™ VORAD ® VS-400 system. Improper alignment can cause the system to improperly detect objects in the vehicle’s path. Every precaution should be taken to ensure the VS-400 alignment (both horizontal and vertical), is correct.
Page 20
Mounting Requirements Horizontal Alignment The Forward Looking Radar must be facing straight ahead (azimuth) of the vehicle in order to optimally detect objects in the vehicle path. Select two truck reference points that are identical and symmetrical about the truck centerline. Ensure the reference points are equally aligned.
Mounting Requirements Mounting Requirements - Side Object Detection (SOD) Side Sensor The Side Sensor should be mounted on the side of the vehicle, between 22" (558.8mm) and 36" (914.4mm) from the ground and at least 18" (457.2mm) rear of the side view mirror (see diagram below). Typically, the Side Sensor is located on the passenger side of the vehicle, however, it can also be installed on the driver side of the vehicle.
Page 22
Mounting Requirements Sensor Orientation The Side Sensor should be orientated so the embossed logo is parallel to the ground. Orientation is crucial for proper operation due to the radar's polarized beam profi le. Mounting the Sensor The sensor should be mounted to the vehicle using 10-24 (6mm) stainless steel hardware. Bolts should be installed from the sensor side, with fl...

Mounting Requirements Mounting Requirements - Driver Interface Unit (DIU) The Driver Interface Unit (DIU) serves as the Bendix VORAD Collision Warning System's central information center. The DIU provides ™ ® the driver with visual and audible alerts, as well as system confi guration, status, and diagnostic information. The DIU uses the vehicle's SAE J1939 data link to communicate with the FLR, and other vehicle system devices.
Page 24
Mounting Requirements Installation The DIU should be located where the driver can easily view and adjust the controls. This can be located on top of, or integrated into, the dashboard fl ush with the front edge of the dashboard. Ease of operation and visibility of the DIU front panel are the primary considerations. The method chosen for routing the wiring harness to the DIU should also be taken into consideration when determining the optimal location.

Electrical Requirements J1939 Note: The J1939 data bus uses two (2) 120-ohm resistors to terminate each end of the data bus on the vehicle. These resistors must remain in place for proper data bus communication. Due to the mounting location of the Forward Looking Radar, the closest of the vehicle's J1939 terminators may have to be relocated nearer the radar as shown in the diagram below.
Electrical Requirements Electrical Requirements - Side Object Detection (SOD) The Side Object Detection (SOD) system consists of two components: a Side Sensor (SS) and a Side Sensor Display (SSD). Power Requirements • Operating Voltage: +9-32Vdc • Power Current: Not to exceed 0.25 amps •...
