Abstract:
A method of steering an articulated wheel loader including a front body portion and a rear body portion, the front body portion including a bucket and a pair of front wheels. The rear body portion is pivotally coupled to the front body portion and includes a pair of rear wheels. The method includes steps of: providing a steering command to steer the wheel loader; detecting an angle that a front longitudinal axis of the front body portion forms with a rear longitudinal axis of the rear body portion; and when the detected angle is greater than a threshold automatically implementing a steering brake function to independently brake one of the pair of front wheels or rear wheels that is on a steering side to reduce a speed of the braked wheel to zero so that the braked wheel becomes a pivot point to minimize a turning radius.
