Working Vehicle Auto-Steering Controls for Forward and Reverse Travel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of automatic steering in working vehicles, such as tractors, can be complex due to the need for the operator to manually move switches according to the vehicle's direction of travel, complicating the process.
Innovation Solution
A working vehicle design with a console-mounted first manual operator for forward travel and a detachable second manual operator attachable rearward of the seat, allowing separate control of automatic steering switches for forward and rearward travel, including position detection and correction functions, and a controller to manage these operations.

Engineering Contradiction Analysis
1Ease of operation
If a single manual operator for automatic steering is provided on the console, then the device structure is simple, but the operator must manually move the switch according to the direction of travel which complicates the operation
Solution Approach 1:
The manual operator for automatic steering is divided into two separate operators: a first manual operator provided on the console for forward travel, and a second manual operator attachable rearward of the seat for rearward travel. This segmentation allows each operator to be positioned optimally for its specific travel direction, eliminating the need for the operator to manually move a single switch and thereby reducing operational complexity.
2Ease of operation
If separate manual operators are provided for forward and rearward travel, then the operation is simplified, but the device structure becomes more complex
Solution Approach 1:
The second manual operator is designed to be detachable and attachable rearward of the operator's seat, allowing it to serve multiple functions: it can be attached when rearward travel is needed and detached when forward travel is needed. This multi-functionality approach provides simplified operation for each travel direction while avoiding the need for two permanently installed complex control systems.

AI summary
To reduce complexity of operation when a working vehicle performs automatic steering, the working vehicle includes a vehicle body to be manually steered with a steering wheel or automatically steered to travel forward or rearward, an operator's seat on the vehicle body, a console located forward of the operator's seat or located on one side of the operator's seat, a first manual operator for automatic steering provided in or on the console, and a second manual operator for automatic steering attachable at a location rearward of the operator's seat.
