Comparison of Methods for Estimating Instantaneous Turn Radius of Ackermann Steering Vehicles
<p>The instantaneous turn radius of an Ackermann steering vehicle is the distance to a point in space about which the vehicle will travel in an arc during a turn. There are at least six ways to estimate instantaneous turn radius and each method uses different inputs and has distinct advantages and …
