Abstract
An articulated work machine has a front frame and a rear frame connected for pivotal movement therebetween for steering the machine by an articulation joint. Each of the front and rear frames has two driven wheels, spaced laterally, each having a brake associated therewith. As the machine articulates during steering, one or more of the wheels may lose traction and slip. An electronic traction control system receives measured wheel speed signals and an articulation angle signal, calculates a desired wheel speed responsive to the wheel speed and articulation angle signals, and selectively applies the brakes until the measured wheel speed is equal to the desired wheel speed.
