Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single analog stick is used for steering control, then the device complexity is low, but the steering precision is insufficient for sloped/banked roads and narrow spaces
Solution Approach 1:
The steering control function is segmented into two independent analog sticks, each handling different aspects of steering control. The first analog stick controls primary steering while the second analog stick provides fine-adjustment capability, allowing precise control on sloped and banked roads without requiring a single complex control mechanism
Solution Approach 2:
The patent adds a second dimension to steering control by introducing dual analog sticks that operate independently. This dimensional addition transforms the control system from single-axis to multi-axis control, enabling precise steering adjustments in complex environments while maintaining manageable device complexity through modular architecture
2Measurement precision
If existing handheld controllers are used, then the ease of operation is maintained, but the control precision is insufficient for challenging terrains
Solution Approach 1:
The control functions are segmented across multiple input devices (two analog sticks and two triggers), with each component handling specific control aspects. This segmentation allows the operator to use only the necessary controls for given terrain conditions, maintaining operational simplicity while achieving high control precision through coordinated input from multiple segmented control elements
Solution Approach 2:
The handheld console is designed with multi-functional controls where the two analog sticks can be configured for different steering modes and the triggers handle both acceleration and braking. This universal design allows a single controller to adapt to various terrain types and operational requirements, providing precise control without requiring multiple specialized devices that would complicate operation
3Adaptability or versatility
If dual analog sticks with customizable calibration maps are implemented, then the adaptability to different terrains is improved, but the device complexity increases
Solution Approach 1:
The calibration maps are implemented as dynamic, reconfigurable parameters rather than fixed hardware configurations. The system can adaptively adjust the relationship between analog stick input and steering output based on terrain conditions, allowing the same physical controller to optimize performance across varied terrains without requiring physical reconfiguration or adding complex mechanical components

AI summary
A method and control system for a vehicle includes a handheld console and a first subsystem controller. The handheld console includes first and second analog sticks, a first controller, and a communication system. The first and second analog sticks are in communication with the first controller. The first controller monitors a first input from the first analog stick, and determines a first steering angle based upon the first input and the first steering calibration map, monitors a second input from the second analog stick, and determines a second steering angle based upon the second input and the second steering calibration map. A final steering angle command is determined based upon the first steering angle and the second steering angle, and is communicated to the first subsystem controller of the vehicle to control the steering system.
