Steering Controller Operator Verification Anti-Theft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Advanced steering systems in vehicles, including those with wireless communication, often have ineffective anti-theft systems that fail to prevent unauthorized use.
Innovation Solution
A steering system with an electric power steering system and a controller that verifies operators, inhibiting operation if unauthorized, by placing the system in a standby mode or locking the vehicle's wheels to prevent movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anti-theft systems (door locks, alarms, steering column lock) are used in vehicles with advanced steering systems, then basic vehicle security is provided, but the anti-theft system becomes ineffective against unauthorized use of the vehicle
Solution Approach 1:
The patent combines the anti-theft verification function with the existing steering system controller, merging security capabilities into the steering control architecture. The controller that manages electric power steering operations also performs operator verification and controls transmission and braking systems, creating an integrated security-steering system that improves anti-theft effectiveness without adding separate complex security hardware
Solution Approach 2:
The steering system controller is designed to perform multiple functions: it manages electric power steering operations, verifies operator identity, controls transmission system states, and manages braking system operations. This multi-functional approach allows a single controller to provide comprehensive security while maintaining steering operations, reducing the need for separate dedicated security system components
2Reliability
If the controller inhibits operation of the electric power steering system in response to a non-verified operator, then unauthorized use is prevented, but the ease of operation for legitimate users is reduced due to verification requirements
Solution Approach 1:
The system performs operator verification before allowing steering system operation, establishing security credentials in advance. The controller checks whether the operator is authorized before enabling electric power steering, transmission control, or braking system operations, preventing unauthorized use while allowing legitimate users to operate the vehicle without interruption during normal use

AI summary
A steering system for an autonomous or semi-autonomous vehicle is provided. The steering system includes a controller that is in communication with an electric power steering system and a transmission control system. The controller is programmed to, in response to a first signal indicative of a non-verified operator and a request to operate, place the electric power steering system in a standby mode and inhibit the transmission control system from changing at least one of a transmission operational state and a transmission operational position.
