Forces at Work
Notice the extreme forces at work on this test vehicle, being driven at high speed and navigating the double lane change course. It is easy to see the body roll and instability of the towing vehicle and compare this to the stability and position of the caravan with ATC fitted and activating.
These red lines illustrate the severe banking of the towing vehicle, and therefore the implied extreme forces that are being applied to the caravan.
1) Also notice the large pressure on the offside tyre of the towing vehicle.
Despite the large forces at work in this critical driving situation, the caravan is entirely level, and is in a controlled position as it completes the lane change. This is a testament to ATC’s performance, clearly showing how it keeps the caravan straight even under significant manoeuvring.
