Work Vehicle Haptic Control for Multi-Component Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern work vehicles with multiple operator control devices can be cluttered and difficult to operate, as each device provides a unique haptic response, making it challenging for operators to determine which component they are controlling by feel.
Innovation Solution
A system and method that utilize a single operator control device to provide distinct haptic responses based on the identified component, using a controller to differentiate the haptic feedback for different vehicle components, such as the engine and work implements, allowing operators to control multiple components with a single device while maintaining unique tactile cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple operator control devices are used to control different components, then each component can be controlled with a unique haptic response, but the cab becomes cluttered and the skill level required to operate the vehicle increases
Solution Approach 1:
The patent combines multiple control functions into a single operator control device. The controller receives a single operator input and dynamically routes it to control different vehicle components (engine, transmission, work implement) based on the current operational context, merging what would traditionally require multiple separate control devices.
Solution Approach 2:
The single operator control device is designed to perform multiple control functions universally. The controller can direct the operator's input to control different components at different times, making one device capable of controlling multiple components that would traditionally require separate dedicated control devices.
2Device complexity
If a single operator control device is used to control multiple components, then the cab is less cluttered, but the operator cannot determine which component is being controlled by feel due to identical haptic responses
Solution Approach 1:
The patent applies local quality by providing context-specific haptic feedback. The controller generates different haptic responses (resistance, vibration, or force feedback) tailored to the specific component being controlled at that moment, allowing the operator to identify the active component through tactile cues even though the physical control device remains the same.
Solution Approach 2:
The system implements feedback by providing haptic responses to the operator based on the current control context. The controller monitors which component is being controlled and adjusts the haptic feedback characteristics accordingly, creating a closed-loop communication that informs the operator of the current operational state through tactile sensation.

AI summary
In one aspect, a system for providing haptic feedback to an operator of a work vehicle may include an operator control device and a controller. The controller may be configured to identify one of a first component of the work vehicle or a second component of the work vehicle as a selected component to be controlled via the operator control device. Furthermore, the controller may be configured to control the operation of the operator control device such that the operator control device provides a first haptic response to the operator when first component is identified as the selected component. Additionally, the controller may be configured to control the operation of the operator control device such that the operator control device provides a second haptic response to the operator when second component is identified as the selected component, with the second haptic response differing from the first haptic response.
