Abstract
A method for automatically adjusting a target ground speed of a machine includes receiving data from a sensor, at a work monitor unit of an electronic control module of the machine, analyzing the data received from the sensor on the work monitor unit, receiving the data from the work monitor unit at a target model unit of the electronic control module, calculating, at the target model unit based on the data, ground engagement data for the machine, receiving the ground engagement data for the machine at a work monitor library unit of the electronic control module, calculating, at the work monitor library unit, the target ground speed, and adjusting a speed of the machine to the target ground speed.
Claims16
A method for automatically adjusting a target ground speed of a machine, the method comprising:
- receiving, by one or more processors of an electronic control module of the machine, data from a plurality of sensors;
- analyzing, by the one or more processors, the data received from the plurality of sensors;
- calculating, by the one or more processors and based on the data, ground engagement data for the machine,
- wherein calculating the ground engagement data includes:
- calculating a target track pull and a target track speed,
- the target track pull and the target track speed being calculated based on information identifying properties of a material on which the machine is operating, including a slope, a side slope, and a temperature of the material on which the machine is operating;
- calculating, by the one or more processors, the target ground speed based on the ground engagement data;
- and
- adjusting, by the one or more processors, a speed of the machine to the target ground speed by adjusting an implement on the machine to adjust an amount of load being applied to the machine.
A method for automatically adjusting a target ground speed of a machine, the method comprising:
- receiving, by one or more processors of an electronic control module of the machine, data from one or more sensors;
- analyzing, by the one or more processors, the data received from the one or more sensors, wherein at least one of the one or more sensors is configured to determine a surface on which the machine is operating and to estimate material properties of the surface on which the machine is operating, including a temperature and either a slope or a side slope of the material on which the machine is operating, and wherein analyzing the data received from the one or more sensors includes determining a raw target track pull and a raw target track speed based on the material properties of the surface on which the machine is operating;
- calculating, by the one or more processors and based on the data, ground engagement data for the machine based on the determined raw target track pull and the determined raw target track speed, wherein calculating the ground engagement data includes calculating a ground speed and calculating a track slip,
- calculating, by the one or more processors and based on the ground engagement data, a target track pull and a target track speed, wherein the target track pull and the target track speed are calculated based on the material properties of the surface on which the machine is operating;
- calculating, by the one or more processors, the target ground speed based on the ground engagement data and based on whether the target track speed is less than or equal to the raw target track speed or whether the target track speed is greater than the raw target track speed;
- and
- adjusting, by the one or more processors, a speed of the machine to the target ground speed.
