Abstract

A vehicle fraction control system for a vehicle having a prime mover, at least one wheel for providing tractive effort on a support surface and being capable of slipping, and a transmission having an input side operably coupled to the prime mover and an output side operably coupled to the at least one wheel. The traction control system includes a controller operable to react to wheel slip by automatically activating a plurality of reactions for reducing wheel slip, wherein the plurality of reactions are tiered such that the controller activates each reaction sequentially in a predetermined order.

Description

technical field [0001] The present invention relates to the regulation of wheel slip or slip in towing vehicles. Background technique [0002] When a towing vehicle, such as a motor grader, is in poor traction conditions, too much wheel slip or skidding can result in poor function of the vehicle and can also degrade the quality of the support surfaces beneath the wheels. Poor traction has been dealt with previously by limiting torque to the electric drive motor, by applying individual wheel brakes to the slipping wheels, and by applying hydrostatic torque drive systems and continuously variable hydraulic drive torque limiting systems condition. Other reactions to wheel slip are generally within the operator's grasp. Contents of the invention [0003] Providing a method for automatic traction control that reduces wheel slip would improve the quality of the support surfaces behind the vehicle, improve vehicle productivity, assist new vehicle operators, and reduce the workl...
