Correction of Long Vehicle Off Tracking by Multiple Axle Steering

2019

When planning the road vehicles for the transport of passengers or goods, engineers should take care to contrast some undesirable phenomena in the lateral dynamics, such as high-speed instability or off tracking. While the former is less troubling in the slow heavy vehicles, the latter is a serious problem due to the risk of invading the neighbouring lanes. The use of multi-wheel steering may completely cancel this drawback and, pursuing an optimized correlation among the steering angles, a functional inter-dependence based on the cubic “witch of Agnesi” is found to be very promising. Simple control systems with electromechanical or electronic components may be easily implemented for the mu…
