Abstract
A working machine includes a body, a ground-engaging propulsion structure supporting the body, a drive arrangement configured to provide motive power to the ground engaging propulsion structure, a braking system actuatable to apply a braking force to the ground engaging propulsion structure, a control system, and a sensor assembly configured to determine an output of the drive arrangement and to provide an output to the control system. The control system is configured to apply a first braking force to the ground engaging propulsion structure that is based on the determined output of the drive arrangement.
Claims20
A working machine comprising:
- a body;
- a ground-engaging propulsion structure supporting the body;
- a drive arrangement configured to provide motive power to the ground engaging propulsion structure;
- a braking system actuatable to apply a braking force to the ground engaging propulsion structure;
- a control system;
- and
- a sensor assembly configured to determine an output of the drive arrangement and to provide an output to the control system,
- wherein the control system is configured to apply a first braking force to the ground engaging propulsion structure that is based on the determined output of the drive arrangement.
A method for operating a working machine comprising:
- a body;
- a ground-engaging propulsion structure supporting the body;
- a drive arrangement configured to provide motive power to the ground engaging propulsion structure;
- a braking system actuatable to apply a braking force to the ground engaging propulsion structure;
- a control system;
- and
- a sensor assembly configured to determine an output of the drive arrangement and to provide an output to the control system,
- wherein the control system is configured to apply a first braking force to the ground engaging propulsion structure that is based on the determined output of the drive arrangement,
- the method comprising the steps of:
- determining whether the speed of travel of the working machine is below a pre-determined threshold and/or whether a rotational speed of the drive arrangement is less than pre-determined threshold;
- and
- applying the first braking force to the ground engaging propulsion structure via the braking system when the determined speed of travel of the working machine is less than the pre-determined threshold or when the determined rotational speed of the drive arrangement is less than the pre-determined threshold.
