Handling & Dynamics

The flexibility of VBOX, combined with custom regulation driven software, is the ideal solution for a variety of ride and handling tests.

Standard procedures for ESC, Centre Line Deviation, Lane Change, and Truck & Trailer testing can be conducted using VBOX data logging equipment along with our application-specific software.

VBOX and Robot Integration

Posted in Handling & Dynamics

Driving robots for steering and throttle/brake control are often used in vehicle testing and development where the test procedures call for absolute consistency that a human driver cannot perform; and also in cases where the manoeuvres are not considered acceptably safe to have a driver at the wheel, or are extremely difficult to carry out (such as the Sine With Dwell element of ESC testing).

For some tests which need the vehicle to take a repeatable and highly accurate drive line – such as AEB or lane change testing - a VBOX 3i RTK is used to provide speed, heading, and positional data to the required accuracy for a driving robot to follow a predefined path.

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

Robots from manufacturers such as Anthony Best Dynamics and DSD are also integrated with VBOX for path-following, allowing for a wide variety of testing of ADAS and vehicle dynamics.

Case Study 

Jag rampIn 2017, Jaguar Land Rover approached Racelogic and VEHICO with the desire to perform a barrel-roll of their new E-Pace car, similar to the stunt originally carried out in the 1974 James Bond feature film “The Man With The Golden Gun”, in which a car is launched from a ramp, spinning through 270° before landing wheels-down.

Remarkable for its time, the original stunt is purportedly the first of its kind to have been computer-modelled. JLR set about recreating it using modern computing methods – but due to the complexity and risk involved, for the initial test runs it was deemed necessary to use a steering and throttle robot.

A test area was built at Santa Pod, the dragstrip in Northamptonshire UK, with a ramp and enormous, custom-built air bag to catch the car after launching.

A VEHICO driving robot was installed along with a VBOX 3i RTK to ensure that the car hit the ramp at precisely the same point and speed every time – a feat not possible by even the best stunt drivers.

This consistency also allowed the ramp design team to make changes based on data with no human error involved.

Here you can see one of the runs from the VEHICO chase car:

Once the ramp design was finalised, Jaguar Land Rover replicated the setup for a press conference held at the Excel centre in London. Stunt driver Terry Grant, who was involved with the project from the beginning, successfully jumped the E-Pace through 270° over 15.3 m – verified by Guinness as a world record.

ESC Testing

The high torque and steering wheel speed required to perform ESC testing means that a robot such as the ABD SR60 is essential. ABD take the VBOX CAN output for speed, heading, yaw and roll rate at 100 Hz and feed it into the robot which conducts and guides the whole test.

The car is 'characterised', by determining the necessary steering angle to achieve the required amount of lateral g (known as a 'Slowly Increasing Steer' procedure). A “Sine with Dwell” test is then performed with increasing yaw and displacement, on both right and left turns.

With this combination of high-accuracy VBOX data and a driving robot, the FMVSS126 test procedures can be conducted with precision and consistency. Learn more on our ESC Testing page.
