Abstract

An auto-start system for a work vehicle includes a data store containing first start and stop initiation conditions; sensors configured to detect information indicative of at least a first parameter; and a controller including at least a start module and a monitoring module and operating in at least a monitoring mode or a cycling mode. In the monitoring mode, the monitoring module evaluates the first start initiation condition in view of the first parameter. In the monitoring mode, the start module generates a start command when the first parameter satisfies the first start initiation condition. Upon generating the start command, the controller operates in the cycling mode. In the cycling mode, the monitoring module evaluates the first stop initiation condition. In the cycling mode, the start module generates a stop command when the first stop initiation condition is satisfied.

Claims

1. An auto-start system for a work vehicle, comprising:

a communications unit configured to receive a monitor request input from a remote device;

a data store containing at least a first start initiation condition, a first stop initiation condition, and a first verification condition;

one or more sensors configured to detect information indicative of at least a first parameter and a second parameter associated with the work vehicle or work vehicle environment;

a controller, with memory and processing architecture for executing vehicle control algorithms, coupled to the communications unit, the one or more sensors, and the data store, the controller comprising at least a start module, a monitoring module, and a verification module and configured to operate in at least a monitoring mode and a cycling mode,

wherein, in response to receiving the monitor request input, the controller initiates operation in the monitoring mode, and

wherein, in the monitoring mode, the monitoring module is configured to evaluate the first start initiation condition in view of the first parameter based on input signals from the one or more sensors,

wherein, in the monitoring mode when the first parameter satisfies the first start initiation condition, the start module is configured to generate a verification request for the verification module;

wherein, after receipt of the verification request, the verification module evaluates the first verification condition in view of the second parameter and generates a verification confirmation when the second parameter satisfies the first verification condition;

wherein, in the monitoring mode, the start module is configured to generate a start command after receipt of the verification confirmation;

wherein, upon generating the start command, the controller is configured to operate in the cycling mode,

wherein, in the cycling mode, the monitoring module is configured to evaluate the first stop initiation condition; and

wherein, in the cycling mode, the start module is configured to generate a stop command when the first stop initiation condition is satisfied; and

a starter device coupled to the controller and configured to energize a prime mover of the work vehicle after receipt of the start command and terminate operation of the prime mover of the work vehicle after receipt of the stop command.

2. The auto-start system of claim 1, wherein the start module generates the start command only when in the monitoring mode.

3. The auto-start system of claim 1, wherein the one or more sensors includes a temperature sensor configured to measure at least one of a coolant temperature or an oil temperature as the first parameter.

4. The auto-start system of claim 1, wherein the one or more sensors includes is a voltage sensor configured to measure a voltage of a work vehicle battery as the first parameter.

5. The auto-start system of claim 1, wherein the monitoring module, in the cycling mode, is configured to evaluate the first stop initiation condition in view of the first parameter and the start module is configured to generate the stop command when the first parameter satisfies the first stop initiation condition.

6. The auto-start system of claim 5, wherein the first start initiation condition is a predetermined minimum temperature and the first stop initiation condition is a predetermined maximum temperature.

7. The auto-start system of claim 1, wherein the monitoring module, in the cycling mode, is configured to evaluate the first stop initiation condition in view of a third parameter, and wherein the third parameter is elapsed time since the generation of the start command.

8. The auto-start system of claim 1, wherein, upon generation of the stop command, the controller is configured to resume the monitoring mode.

9. The auto-start system of claim 1, wherein, upon generation of the start command, the start module further generates an activation command for at least one of a transmission system or a hydraulics system of the work vehicle.

10. The auto-start system of claim 1, wherein the start module is configured to restrict movement of the work vehicle in the cycling mode.

11. The auto-start system of claim 1, wherein the data store, the one or more sensors, the controller, and the starter device are arranged on-board the work vehicle.

12. The auto-start system of claim 1, wherein at least one of the data store or the controller is remote relative to the work vehicle.

13. The auto-start system of claim 1, wherein the one or more sensors includes an optical sensor configured to capture an image of the work vehicle as the information indicative of the second parameter, and wherein the verification module is configured to determine the second parameter from the image.

14. A method for automatically starting a work vehicle, comprising the steps of:

receiving, by a communications unit, a monitor request input from a remote device;

initiating, by a controller, operation in a monitoring mode in response to the monitor request input;

receiving, in the monitoring mode by the controller, a first sensor signal indicative of a first parameter associated with the work vehicle;

evaluating, in the monitoring mode by the controller, a first start initiation condition stored in a data store in view of the first parameter;

generating, in the monitoring mode by the controller, a verification request when the first parameter satisfies the first start initiation condition;
