Lane Change Testing with VBOX
You can record all the required parameters for lane change testing using a VBOX 4 and VBOX IMU, which, along with our free Lane Change testing software, allows you to easily and accurately carry out lane change manoeuvres which fall in line with the "Elk Avoidance Test" / ISO3888-2 standard. Lane change manoeuvres provide a good indication of the stability and control of a vehicle.
Using two lanes of cones with widths corresponding to the width of the vehicle, lane change manoeuvres are carried out by driving through a tight first lane, before swerving hard into a second lane, and then swerving back into the original lane, as shown right and below. The purpose of lane change testing is to reproduce a sudden avoidance manoeuvre that can cause vehicles to lose control.
Highly Accurate
The VBOX 4 data logger provides highly accurate measurements of speed, distance and heading. It is available with dual antennas and RTK for centimetre-level position accuracy.
Robot Integration
VBOX equipment can be used with Anthony Best Dynamics and VEHICO driving robots, to achieve the necessary level of consistency.
Live Display
VBOX Test Suite installed on a Windows device within the test vehicle offers real-time display of all measured parameters and test results, which is useful when performing a "witness" test.
ISO3888-2 Compliant
VBOX equipment makes it easy to perform lane change manoeuvres which fall in line with the "Elk Avoidance Test"/ ISO3888-2 standard.
Video Integration
VBOX Video loggers offer synchronised video and data with real-time graphical overlay, showing the speeds achieved to establish pass or fail.
Intuitive Analysis Software
VBOX Test Suite with dedicated Lane Change Plugin
The Lane Change test plugin is designed to easily and accurately carry out the ISO 3888-2 'Moose (or Elk) Avoidance Test using a VBOX 4 data logger and IMU.
VBOX Test Suite allows you to set the start and finish points of the test, and will record each test manoeuvre. One button configuration allows you to configure the VBOX 4 and IMU for the test.
A dedicated result's area shows four runs of various speeds, speed on entrance and speed on exit, along with percentage difference and time, which are all recorded to establish the validity of each test.
A graph also illustrates speed and yaw rate against time, whilst the map logs the trajectory of the vehicle.
Testing Equipment
Lane Change Testing can be conducted using a VBOX 4 in conjunction with a VBOX Inertial Measurement Unit (IMU).
Measured Parameters
- Vehicle speed (0.1 km/h RMS)
- Vehicle heading (0.1° RMS)
- Yaw rate (0.014° /s)
- Lateral G
- Steering Angle (either from Vehicle CAN or external sensor)
High Accuracy Data
VBOX 4 Dynamics is the first choice for vehicle dynamics testing and well-suited for advanced handling tests, including ESC assessments, lane change maneuvers, and precise tire testing, delivering critical data on vehicle dynamics and stability. It stands out in scenarios where accurate slip angle measurements are essential.
Pitch, Roll and Yaw Measurements
VBOX IMU05 adds crucial attitude channels - Yaw, Pitch, and Roll - which are essential for vehicle dynamics and ADAS testing to analyse lateral and longitudinal movements, including Slip Angle and Vehicle/Body Heading.
Robot Integration
VBOX equipment can be used with Anthony Best Dynamics and VEHICO driving robots, to achieve the necessary level of consistency.
