Blind Spot Detection System Testing

Overview

Blind Spot Detection Systems (BSDS) use cameras, radar sensors, light detection or ultrasonic systems to warn a driver whenever another object enters the blind spot area of a car.

With real-time measurement of parameters from up to three vehicles and at better than 2cm positional accuracy, the VBOX test system allows manufacturers to verify the effectiveness of their Blind Sport Detection system easily and reliably.

At the core of the system is RACELOGIC's flagship data logger, the VBOX 3i Dual Antenna with RTK (VB3iSLR), connected via radio telemetry to an RTK Base Station or to another VB3iSLR acting as a moving base.

For a list of all standard GPS data channels and accuracies that are also measured please refer to the VBOX 3i Dual Antenna with RTK product page.

Multiple Target Capability

The 'Multiple targets' feature of the BSD test equipment is capable of calculating parameters from two target vehicles at the same time.

Open Road Testing

By substituting the DGPS Base Station with a specially configured VBOX 3i Dual Antenna with RTK, our MOVING BASE test setup allows users to test and verify active safety systems outside the test track. VBOX Moving Base enables you to ...

Video Integration

When used in conjunction with a VBOX video system, the measured parameters can be graphically overlaid onto the recorded video, providing a clear visual reference to the performance of the test.

Graphical overlay is totally user configurable and can be easily altered to present relevant information according to the tests being conducted.

Free Analysis Software

VBOX Tools Analysis Software is a flexible and powerful package which allows for detailed post processing of the logged files in order to test the accuracy of your ADAS system. A laptop running VBOX Tools can be used to monitor the measured parameters in real time, either by a serial, USB, or Bluetooth connection. For Video VBOX files, video can be viewed synchronized with the data within the software.

BSD warning signals

If the vehicle carries the BSD operation data on its CAN Bus, this can be simultaneously logged (and displayed in video if a Video VBOX is also being used) alongside that of the GPS data, giving you an exact comparison between relative vehicle position and onboard strategy data.

Multiple Contact Points

To assist in the testing of ADAS applications such as Blind Spot Monitoring and Rear Cross Path Detection, it is now possible to ‘map’ the shape of vehicles using a survey pole, antenna, and VBOX Manager. Up to twenty-four points around the vehicle bodies can be surveyed, and the ‘shape’ of each car can be stored for later use. As the test is conducted, the distance of the closest contact points between the vehicles is calculated to +/-2cm accuracy, automatically switching to the nearest contact points as they change with the car’s relative positions.

This allows for multiple procedures to be completed without having to reconfigure for individual contact points – such as moving from right rear to left rear flank during blind spot testing. This video demonstrates how the system works:

VBOX Test Systems

Blind Spot Detection testing and validation can be conducted on the test track using a static DGPS Base Station, or via the Moving Base solution. Depending on the test requirements, you can choose between three VBOX system bundles.

VBOX 3i RTK (x2)
100Hz GPS data logger in both the subject and target vehicle

Each RLVB3iSLR logs up to 64 channels simultaneously (excl. standard GPS).

Several Radio Pairs
Used to transmit/receive differential correction signals, for VBOX to VBOX or VBOX to PC communication.

There are a variety of telemetry systems available, employing a range of frequencies.

DGNSS Base Station RTK
Enables a positional accuracy of ±2cm.

The RLVBBS4RG comes with antenna and is able to transmit RTCM, CMR, RTCMV3 or RL proprietary (2cm) correction messages via radio.


VBOX CAN Hub The RLVBCANHUB allows for additional external modules to be connected to a VBOX 3i. Its footprint is the same as the VBOX 3i, so it can sit neatly underneath.		Tripod for GPS Antenna The VBBSTRIPOD2 enables the Base Station GPS Antenna to be mounted at a suitable height, at a non-permanent track side location.		Camera Mounting Arm (optional) Adjustable mounting arm for use with video cameras.


Video VBOX Pro (optional) When used in conjunction with Video VBOX or VBOX HD, the measured parameters can be graphically overlaid in real-time onto the recorded video.		Preview Monitor (optional) The Preview Monitor comes with the Video VBOX and enables you to align the cameras on the vehicle.
