Digital hardware method, system and device for preventing the initial onset of trailer oscillations and control thereof
First Claim
1. A method for digitally detecting and preventing an initial onset stage and further fundamental development of trailer and towing vehicle oscillations, swaying and snaking movements, wherein a plurality of digital IMUs (Inertial measurement units) are affixed to the trailer and towing vehicle, the method comprising:
- continually monitored in parallel execution by a digital hardware based FPGA (Field Programmable Gate Array) central controller in real-time, the trailer and towing vehicle movements;
detecting and identifying by the plurality of digital, parallel processed IMUs, the initial onset stage and further fundamental development of trailer and towing vehicle oscillations, swaying and snaking movements, wherein speed of towing vehicle is automatically increased whilst simultaneous application of trailer braking is immediately applied to the trailer wheels without application of the towing vehicle brakes.

Abstract
A digital autonomous hardware based FPGA (Field Programmable Gate Array) device and method for preventing the initial onset of trailer oscillations and swaying (“Snaking”) movements and subsequent control thereof. The device being a detection and control method for any wheeled trailer which is detachable from the towing vehicle. The system uses a Kalman Filter to processes digital data from a number of wireless IMUs (Inertial Measurement Units) located on the trailer and towing vehicle and then subsequently digitally controls the application and monitoring of simultaneous braking to the trailer while accelerating the towing vehicle in a safe manner in an attempt to quickly alleviate and stop all oscillations and swaying (“Snaking”) movements. The system includes a number of other ancillary safety related features.
