It was my friend who over turned, she had her twin boys in the car but all are ok just a bit shook up. Caused by being cut up on the inside by a speeding motorist causing her to brake hard and loose control. The car didn't stop so she's hoping it got caught on cctv.
should have a dash cam fitted for this very reason.we have fitted a system in our trucks that records all around the truck from 5 cameras including 1 watching driver.the driver has no access to the hard drive.
It is my understanding that a dash cam probably would not have helped as it probably would not have kept the footage of the incident of the car cutting up the towing car as the incident of the accident only occured seconds after the car had left the scene as no collision.
Why would the dash cam not save the footage? Depending on the memory card you can get 4 - 8 hours typically before it starts overwriting the old clips.
They usually have enough power to save the current clip even if power is cut instantly, and some will record for a good while afterwards.

as a design engineer i would like to know more about your system and how it works. i have had a few ideas of friction dampers and remote, electrical actuation of the caravans brakes, would that even straighten out a sway? but cant visualise a differential lever (if thats what it is) built into the hitch.
Hi Baileyjake
If you are a design engineer you will at least have an understanding of the things I mention in my posts - you also understand why I am so reticent at disclosing to much. However, I can help you with some of the above. The objective I was working on was to avoid the use of electronics where it is possible to do without. I am a technology fanatic and worked on the most sophisticated of them all on trucks where it is absolutely essential eg Can Bus systems. I can state with confidence that there are no electronics today that are robust enough to withstand the rigors of operating under or around vehicles. I love ESP and it has saved the day on more occasions I can count simply because a driver cannot ever do what it does, however, due to the fact it works using very small currents/signals, leakage is a problem.
I designed my DSS 20 years ago and put it on the shelf until recently. I know of a number on the Patent prior art that are similar but have never got to market because they fail to meet the "Simple Harmonic Motion" Criteria using mechanical means only so they input electrical switches etc or use silly dampers that people will not tolerate so they never make it. I think the industry leaders believe mine is one of them - how wrong they are. Please do not try this at home like some may do - if it is not done correctly it can induce a sway using Differential concepts. I imagine there are many trying to fathom how I do it.
It is a precision mechanism that is out of sight, cannot fail to stop lateral sway and will reduce risk of jackknife by approx 90% of cases. Speed has no effect on the operation or sensible loading
I have used it in France at 82 mph/130 kph legally - not a sign of sway even when I pass trucks - it's scary at that speed because of the potential of things going wrong so I stick to 90 kph.

PS You cannot alter the Hitch - it is type approved.
