Abstract

In one aspect, a system for providing brake-assisted steering to a work vehicle may include at least one sensor configured to detect at least one parameter associated with a wheel speed differential defined between first and second wheels of the work vehicle. The system may also include a controller configured to determine a target wheel speed differential between the first and second wheels when it is determined that a change in the direction of travel of the work vehicle has been initiated. Furthermore, the controller may be configured to control the operation of a first or second braking device of the work vehicle such that a braking force is applied to an inside wheel of the work vehicle in a manner that adjusts the wheel speed differential towards the target wheel speed differential.

Dependent claims

A system for providing brake-assisted steering to a work vehicle, the system comprising:

first and second wheels, one of the first or second wheels corresponding to an inside wheel of the work vehicle and another of the first or second wheels corresponding to an outside wheel of the work vehicle when a direction of travel of the work vehicle is being changed;
first and second braking devices, the first braking device configured to apply a braking force to the first wheel, the second braking device configured to apply a braking force to the second wheel;
at least one sensor configured to detect at least one parameter associated with a wheel speed differential defined between the first and second wheels;
and
a controller communicatively coupled to the at least one sensor, the controller configured to determine a target wheel speed differential between the first and second wheels when it is determined that a change in the direction of travel of the work vehicle has been initiated, the controller further configured to control an operation of the first braking device or the second braking device such that a braking force is applied to the inside wheel in a manner that adjusts the wheel speed differential towards the target wheel speed differential.

A method for providing brake-assisted steering to a work vehicle, the method comprising:

controlling, with a computing device, an operation of a work vehicle such that the work vehicle is moved along a direction of travel, the work vehicle including first and second wheels, one of the first or second wheels corresponding to an inside wheel of the work vehicle when the direction of travel of the work vehicle is being changed, the work vehicle further including a first braking device configured to apply a braking force to the first wheel, and a second braking device configured to apply a braking force to the second wheel;
determining, with the computing device, a target wheel speed differential between the first and second wheels when a change in the direction of travel of the work vehicle has been initiated;
controlling, with the computing device, an operation of the first braking device or the second braking device such that a braking force is applied to the inside wheel in a manner that adjusts a wheel speed differential defined between the first and second wheels towards the target wheel speed differential.
