Single pedal propulsion system for straight travel of work vehicle
First Claim
1. A work vehicle that is selectively operable in a first steering mode and a second steering mode, the work vehicle comprising:
- a chassis;
a first traction device supporting the chassis;
a second traction device supporting the chassis;
a first steering input device that is configured to control movement of the first traction device in the first steering mode; and
a second steering input device configured to control movement of (i) the second traction device in the first steering mode and (ii) the first traction device and the second traction device in the second steering mode; and
a controller configured to;
cause the work vehicle to enter the first steering mode in response to detecting that a steering mode input device is in a first position;
cause the work vehicle to enter the second steering mode in response to detecting that the steering mode input device is in a second position;
when the steering mode input device is in the second position, detect a manipulation of the first steering input device; and
in response to detecting the manipulation of the first steering input device when the steering mode input device is in the second position, cause the work vehicle to switch from the second steering mode to the first steering mode.

Abstract
A work vehicle is disclosed with a propulsion system that is selectively operable in a first, turning mode or a second, straight mode. The vehicle includes a first traction device, a second traction device, a first steering input, and a second steering input. In the first, turning mode, an operator is able to steer the vehicle left, right, or straight by independently operating the first and second traction devices via the first and second steering inputs. In the second, straight mode, the operator is able to steer the vehicle straight by operating both the first and second traction devices together via one of the first and second steering inputs.

11. A work vehicle including:
-
a chassis; at least one left traction device supporting the chassis; at least one right traction device supporting the chassis; a left steering input device; a right steering input device; a mode selector operable to switch between a first steering mode and a second steering mode, wherein; in the first steering mode, the at least one left traction device is configured to be operated by the left steering input device and the at least one right traction device is configured to be operated by the right steering input device to steer the work vehicle left, right, or straight, and in the second steering mode, the at least one left traction device and the at least one right traction device are configured to be operated together by the left steering input device to steer the work vehicle straight; and a controller configured to; cause the work vehicle to enter the first steering mode in response to detecting that the mode selector is in a first position; cause the work vehicle to enter the second steering mode in response to detecting that the mode selector is in a second position; when the steering mode input device is in the second position, detect a manipulation of the right steering input device; and in response to detecting the manipulation of the right steering input device when the steering mode input device is in the second position, cause the work vehicle to switch from the second steering mode to the first steering mode. - View Dependent Claims (12, 13)

14. A method comprising:
-
causing, by a controller, a work vehicle to enter a first steering mode in response to detecting that a mode selector input is in a first position, wherein the work vehicle is configured to control a first traction device and a second traction device together in response to manipulation of a first steering input device when in the first steering mode; detecting, by the controller and when the mode selector input is in the first position, a manipulation of a second steering input device; and in response to detecting the manipulation of the second steering input device when the steering mode input is in the first position, causing, by the controller, the work vehicle to switch from the first steering mode to a second steering mode in which the work vehicle is configured to control the first traction device in response to manipulation of the first steering input device and control the second traction device in response to manipulation of the second steering input device. - View Dependent Claims (15, 16, 17)
