BSD,Blind Spot Detection System Testing


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.

System Features
• Measured Paramaters
• Multiple Target Capability
• Open Road Testing
• Video Integration
• Free Analysis Software
• BSD Warning Signals
• Multiple Contact Points

Measured Parameters
• Speed for target and subject vehicle
(0.1km/h RMS)
• Separation time (0.05s)
• Longitudinal separation (0.02m RMS)
• Lateral separation (0.02m RMS)
• Yaw rate for target and subject vehicle (depends on antenna separation)
• Angle to target vehicle (0.1º RMS)
• BSD warning signal output
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:
