Steering curve calibration method and apparatus for a rubber tired paver
First Claim
1. An apparatus for controlling the steering of a directionally steered machine having a set of left and right independently driven wheels and a set of steered wheels, comprising:
- a steering angle sensor that produces a steering angle signal indicative of the angle of the steered wheels;
wheel speed sensors that produce wheel speed signals indicative of the rotational speeds of the left and right driven wheels; and
a controller that receives the wheel speed and steering angle signals, responsively generates a programmable curve that represents the resulting driven wheel speeds as a function of the angle of the steered wheels, and stores the generated curve in a software map.

Abstract
In one aspect of the present invention, a method for controlling the steering of a directionally steered machine having a hydrostatic system that drives a plurality of driven wheels is provided. The method includes the steps of producing a steering angle signal indicative of the angle of the steered wheels and a wheel speed signal indicative of the rotational speed of the driven wheels, and generating a programmable curve that represents the resulting driven wheel speeds as a function of the angle of the steered wheels. The generated curve is then stored in a software map to be later used to determine the driven wheel speeds based on the angle of the steered wheels.
