Abstract

A utility vehicle comprises a plurality of ground engaging members and a frame supported by the plurality of ground engaging members. The frame includes a front frame portion, a mid-frame portion, and a rear frame portion. The utility vehicle further comprises an attachment supported at the front frame portion. Additionally, the utility vehicle includes an operator area supported by the frame and including an operator seat and an adjacent passenger seat spaced apart from the operator seat. The operator seat and the passenger seat are in a side-by-side arrangement. The utility vehicle also comprises an auxiliary power assembly having an attachment shaft configured to be operably coupled to the attachment. The attachment shaft extends in a generally longitudinal direction of the utility vehicle and projects outwardly from the front frame portion.

First claim

What is claimed is:

1. A method of controlling a vehicle, the method including:
detecting, by a vehicle controller, a work attachment coupled to a frame of the vehicle, the vehicle including an engine and an auxiliary power system driven by the engine, the auxiliary power system being configured to provide power to the work attachment, the work attachment including an identification device in communication with the vehicle controller;
determining, by the vehicle controller, a type of the work attachment based on the identification device, the type of the work attachment including at least one of a plurality of different types of work attachments each having a corresponding work function; and
adjusting, by the vehicle controller, an operation of the vehicle based on the determined type of the work attachment.

2. The method of claim 1 , wherein the adjusting the operation of the vehicle includes limiting a maximum speed of at least one of the engine and the vehicle to a maximum speed threshold.

3. The method of claim 1 , wherein the vehicle includes a plurality of wheels driven by the engine, and wherein the adjusting the operation of the vehicle includes changing the number of wheels that are driven by the engine.

4. The method of claim 1 , wherein the work attachment includes at least one sensor in communication with the vehicle controller and configured to detect an operating condition of the work attachment, the method further including monitoring for a fault with the work attachment based on the at least one sensor.

5. The method of claim 4 , further including, upon detecting the fault, at least one of limiting operation of the attachment and providing a fault warning message to a user interface of the vehicle.

6. The method of claim 4 , wherein the at least one sensor is configured to detect at least one of a vibration of a component of the work attachment and a rotational speed of a component of the work attachment.

7. The method of claim 1 , wherein the identification device of the work attachment and the controller communicate over a controller area network (CAN), and wherein the determining the type of the work attachment includes identifying a network address of the identification device of the work attachment.

8. The method of claim 1 , wherein the adjusting the operation of the vehicle includes retrieving vehicle configuration settings stored in memory accessible by the vehicle controller based on the determined type of the work attachment and adjusting the operation of the vehicle based on the vehicle configuration settings.

9. The method of claim 1 , wherein the vehicle further includes at least one ground engaging member, a frame supported by the at least one ground engaging member, a powertrain supported by the frame and including a transmission, and an operator input device in communication with the vehicle controller for controlling the work attachment.

10. The method of claim 9 , wherein the vehicle further includes an operator area supported by the frame and including an operator seat and a passenger seat, a shear panel positioned forward of the operator area and being coupled to a front frame portion of the frame, and a heating, ventilation, and air condition (“HVAC”) system supported by the frame and positioned rearward of the shear panel, the HVAC system including at least one condenser positioned below the operator seat and an evaporator coupled to the shear panel.

11. The method of claim 1 , wherein the work attachment is coupled to the frame.

12. The method of claim 1 , wherein the identification device is in communication with the vehicle controller over a communication network, the vehicle controller being operative to identify a network address of the identification device and to control at least one operation of the vehicle.

13. The method of claim 1 , wherein determining the type of the work attachment is based on communication with the identification device.
