Under-Seat Controller Layout for Motor-Steered Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The placement of a controller to control a motor-driven steering shaft in a work vehicle can compromise driver operability and visibility, as it may obstruct pedals and reduce the driver's field of view.
Innovation Solution
The controller is strategically located on a partition below the driver's seat within the cockpit, allowing for optimal placement close to the motor while minimizing obstruction and interference with the driver's operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller is placed in the cockpit area to control the motor-driven steering shaft, then the control function is achieved, but the driver's visibility and pedal operability are compromised
Solution Approach 1:
The controller is relocated from the horizontal plane (cockpit area) to the vertical dimension (below the driver's seat). This dimensional shift allows the controller to be positioned in the partition space underneath the seat, eliminating obstruction to the driver's forward view and pedal access while maintaining proximity to the motor for control functionality
2Reliability
If the controller is placed close to the motor for efficient control, then control responsiveness is improved, but the driver's field of view and pedal accessibility are reduced
Solution Approach 1:
The controller is positioned in the vertical space below the driver's seat, utilizing the partition area that extends downward. This allows the controller to remain close to the motor for responsive control while being located beneath the driver's line of sight and pedal reach, thus maintaining control reliability without compromising visibility
Solution Approach 2:
The controller is nested within the partition structure below the driver's seat, utilizing the existing spatial configuration of the vehicle. This nesting approach allows the controller to occupy the under-seat partition space, keeping it close to the motor while ensuring it does not interfere with the driver's operational space

AI summary
[Problem] To provide a work vehicle with a controller to control a motor, which is capable of being appropriately located in the work vehicle. [Solution] An exemplary work vehicle includes a driver's seat, a steering wheel located in front of the driver's seat, a steering shaft connected to the steering wheel, a motor to rotate the steering shaft, and a controller to control the motor. The controller is located on a partition below the driver's seat that constitutes a cockpit in which a driver gets.
