Abstract
Official abstract text for this publication.
A method of operating a ride control system of a machine having an accumulator is provided. The method includes detecting a pressure at the accumulator. The method includes generating a first set of input data associated with a drive system and a brake pedal. The method includes generating a second set of input data associated with a lift cylinder. The method also includes determining a working mode of the ride control system based on the first set of input data and the second set of input data. The working mode of the ride control system includes a normal mode and an exposed mode. The method includes operating a ride control activation solenoid valve, upon determining the pressure at the accumulator to be above a predefined threshold, and the working mode of the ride control system to be the exposed mode.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating a ride control system of a machine having an accumulator, the method comprising: detecting, by a first set of sensors, a pressure at the accumulator; generating, by a second set of sensors, a first set of input data associated with a pressure in a drive system of the machine and a brake pedal of the machine; generating, by a third set of sensors, a second set of input data associated with a lift cylinder of the machine; determining, by a controller, a working mode of the ride control system, based on the first set of input data and the second set of input data, as one of a normal mode and an exposed mode, the normal mode including the pressure at the accumulator in a first range and a pressure at the head end chamber of the lift cylinder in a second range, and the exposed mode including the pressure at the accumulator in a third range greater than the first range and a pressure at the head end chamber of the lift cylinder in a fourth range greater than the second range; and operating a ride control activation solenoid valve, upon determining the pressure at the accumulator to be above a predefined threshold and the working mode of the ride control system to be the exposed mode, to deactivate the ride control system.
