Lane Change Testing with VBOX 

You can record all the required parameters for lane change testing using a VBOX 3i 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 3i data logger provides highly accurate measurements of speed, distance and heading. It is available with single or dual antennas, and also 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

Our user-friendly, intuitive data analysis software makes the process of recording and analysing your test data as quick and easy as possible.

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 3i 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 3i 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 3i 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

Using the latest GPS / GLONASS receiver that updates 100 times per second, the VBOX 3i is ideal for high dynamic applications.

Pitch, Roll and Yaw Measurements

The IMU04 provides highly accurate measurements of pitch, roll and yaw using three rate gyros, as well as x, y, z acceleration via three accelerometers.

Robot Integration

VBOX equipment can be used with Anthony Best Dynamics and VEHICO driving robots, to achieve the necessary level of consistency.

Robot Integration

For tests which require the vehicle to take a repeatable and highly accurate drive line a VBOX 3i RTK can be used to provide speed, heading, and positional data to the required accuracy for a driving robot to follow a predefined path.

The example of a lane change manoeuvre in the video below shows the level of consistency that can be achieved with a VEHICO steering robot using the VBOX as a 'motion pack' for path-following applications.
