Remote Steering Angle Synchronization for Autonomous Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicles face challenges in maintaining synchronized steering angles during remote control, leading to potential accidents due to mismatched steering angles between the vehicle and the control system.
Innovation Solution
A control system that synchronizes the steering angle of an autonomous vehicle with a steering input device by using vehicle-specific steering characteristics, including torque and maximum steering angles, to prevent accidents by adjusting the steering angle and limiting acceleration when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is implemented without steering angle synchronization, then ease of operation is improved, but reliability deteriorates due to mismatched steering angles
Solution Approach 1:
The control system receives real-time feedback from the autonomous vehicle about its current steering angle and uses this information to synchronize the steering angle of the steering input device. The processor continuously monitors the vehicle's steering angle and adjusts the steering input device's angle to match, ensuring both systems remain synchronized during remote control operation.
Solution Approach 2:
The system applies vehicle-specific steering characteristics (torque characteristics and maximum steering angles) to the steering input device before remote control begins. This preliminary configuration ensures that the steering input device is properly calibrated to match the autonomous vehicle's steering behavior, preventing synchronization issues from the outset.
2Reliability
If steering angle synchronization is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The processor performs multiple functions: it receives remote control commands, monitors the autonomous vehicle's steering angle, synchronizes the steering input device's angle, and applies vehicle-specific steering characteristics. By consolidating these functions into a single control system component, the patent reduces overall system complexity while maintaining reliability.
3Manufacturing precision
If vehicle-specific steering characteristics are applied, then manufacturing precision is improved, but adaptability decreases
Solution Approach 1:
The system stores steering characteristics (torque characteristics and maximum steering angles) as adjustable parameters for different vehicle types. The processor selects and applies the appropriate parameter set based on the specific autonomous vehicle being controlled, allowing precise matching for each vehicle type while maintaining the ability to adapt to different vehicles through parameter configuration rather than hardware changes.
