Gone are the days of using rulers to measure how close the vehicle is parked to curbs or other objects! The VBOX Test Suite Park Assist plugin works in conjunction with VBOX Hardware to provide live data analysis for testing in different types of parking spaces.
With real-time measurement and positional accuracy at better than 2 cm, the VBOX testing system captures the data that automotive and sensor manufacturers require to verify the effectiveness of their Park Assist system.
At the core of the system is RACELOGIC’s flagship data logger, the VBOX 3i RTK, connected via radio telemetry to an RTK Base Station. It allows you to survey the parking bay before using the equipment inside the vehicle to measure distances between the vehicle and the measured parking space.
Compatible in both bay and parallel parking environments, the Park Assist software allows users to easily set test criteria according to their products and the markets in which they operate.
What’s more, users only need to map out the same space once, allowing simultaneous tests to be carried out conveniently before easily comparing results. The software will even tell the user if the test has passed or failed their own pre-determined criteria.

For a list of all standard GPS data channels and accuracies that are also measured please refer to the VBOX 3i RTK page.
When used in conjunction with VBOX Video, the measured parameters can be graphically overlaid in real time 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.
A ruler generated graphical overlay can be aligned to real-world measurements to ensure that the visual reference is accurate.
Park Assist is a plugin that integrates seamlessly with the VBOX Test Suite (VBTS) and complements the range of VBOX software plugins already available, such as Lane Change and Autonomous Emergency Braking testing.
Park Assist allows you to easily measure distances between any point of the test vehicle to the parking bay lines or other objects of interest such as kerbs, bollards and parked vehicles.
The software allows the shape of the test vehicle as well as the features of the parking bay to be configured. Live values of the measured distances are displayed with a graphical representation of the test being conducted.
Results are immediately validated against the Test Engineers custom criteria.
VBOX Test Suite has been developed to make the process of analysing your test results as quick and clear as possible by combining a clean layout with the ability to compare sets of data simultaneously using multiple test conditions.
It does this by using separate tabs for each test, enabling you to compare different vehicles or set-ups without having to reset your test parameters each time, or search through multitudes of data on a single screen.
The software also uses context sensitive menus to make it easy for you to manage your data and can be used in either ‘Offline’ mode, for post-test analysis, or ‘Online’ mode so you can see your data in real-time.
If the vehicle carries the Park Assist operation data on its CAN Bus, this can be simultaneously logged (and displayed in video if a VBOX video logger is also being used) alongside that of the GPS data, giving you an exact comparison between relative vehicle position and onboard strategy data.
If you cannot use the vehicles’ own CAN system, an AVAD3 audio & visual detector from DTC Solutions can be used alongside VBOX to record when an ADAS system has become active. The AVAD3 is capturing acoustic and optical alerts and signals generated by the vehicle’s advanced driver assistance system.
It produces a CAN or digital signal when recognising changes of the shapes and colors of defined icons or when audible signals are identified. The output of the AVAD3 can then be used by the VBOX to log the exact moment the vehicle safety message is displayed to the driver.
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).
Inertial Measurement Unit
When used in conjunction with VBOX 3i, data from the IMU can be seamlessly integrated with GPS to produce pitch and roll angle accurate to 0.1˚ (RMS) as well as smoother velocity data. This ensures GPS data even when satellite reception is interrupted.
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.
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.
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.
Survey Trolley (optional)
The Survey Trolley Kit allows for the accurate surveying of a lane edge, necessary when performing ACC tests along a curved lane.
VBOX systems are suitable for the following test scenarios:
