Abstract
A system for automated movement of a ground engaging blade of a machine includes a sensor on the blade to indicate a measured roll rate of the ground engaging blade. A controller determines whether the operator roll rate command is within an expected range of the roll rate signal. Movement of the ground engaging blade is at least in part based upon the operator roll rate command.
Claims20
A control system for automated movement of a ground engaging blade of a machine, the ground engaging blade being configured for rotational movement, comprising:
- a sensor located on the ground engaging blade configured to provide a roll rate signal indicative of a measured roll rate of the ground engaging blade;
- and
- a controller configured to:
- receive the roll rate signal;
- receive an operator roll rate command signal;
- determine whether the operator roll rate command is within an expected range of the roll rate signal;
- generate a command signal based at least in part on the operator roll rate command signal;
- and
- transmit the command signal to control movement of the ground engaging blade.
A controller implemented method of adjusting a ground engaging blade of a machine, the ground engaging blade having a sensor configured to provide a roll rate signal indicative of a measured roll rate of the ground engaging blade, comprising:
- receiving the roll rate signal within a controller;
- receiving an operator roll rate command signal within the controller;
- determining whether the operator roll rate command is within an expected range of the roll rate signal;
- generating a command signal within the controller based at least in part on the roll rate signal and the operator roll rate command signal;
- and
- transmitting the command signal from the controller to control movement of the ground engaging blade.
A machine comprising:
- a ground engaging blade;
- a sensor located on the ground engaging blade configured to provide a roll rate signal indicative of a measured roll rate of the ground engaging blade;
- and
- a controller configured to:
- receive the roll rate signal;
- receive an operator roll rate command signal;
- determine whether the operator roll rate command is within an expected range of the roll rate signal;
- generate a command signal based at least in part on the roll rate signal and the operator roll rate command signal;
- and
- transmit the command signal to an electro-hydraulic system to control movement of the ground engaging blade.
