Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supervised partially autonomous vehicle systems face issues with user input validation, particularly when the mobile phone's operating system fails to correctly interpret user inputs, leading to incorrect validation and potential unsafe vehicle operations.
Innovation Solution
A vehicle system that includes a transceiver, a user interface, and a user presence module to iteratively transmit challenge requests to a mobile smart device, receive and validate user responses, and confirm user presence before executing supervised partially autonomous applications, ensuring accurate user input validation and preventing unsafe operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile phone's operating system is used to interpret and validate user inputs, then the ease of operation is improved, but the reliability of user input validation deteriorates due to incorrect interpretation leading to unsafe vehicle operations
Solution Approach 1:
The patent introduces an intermediary validation layer between the mobile phone's operating system and the vehicle control system. Instead of relying solely on the mobile phone to interpret user inputs, the system captures raw input data, transmits it to the vehicle, and performs independent validation against expected input parameters. This intermediary step prevents incorrect interpretations from compromising vehicle safety while maintaining the ease of using a mobile phone interface.
2Reliability
If user presence validation is performed through iterative challenge requests, then the reliability of user presence confirmation is improved, but the loss of time increases due to multiple validation steps
Solution Approach 1:
The system performs preliminary validation by establishing a trusted communication channel between the mobile device and vehicle before the supervised partially autonomous application begins. User presence and device authentication are confirmed in advance, creating a pre-established trust relationship. During application execution, this allows for faster validation cycles since the foundational authentication has already been completed, reducing the time penalty of iterative challenge requests.
3Measurement precision
If the vehicle validates user responses independently rather than relying on the mobile device, then the measurement precision of user input validation is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the critical validation function from the mobile device's operating system and implements it independently within the vehicle's control system. The vehicle receives raw user input data and expected input parameters from the mobile device, then performs independent comparison and validation. This extraction ensures measurement precision by eliminating reliance on the mobile OS's interpretation, while the modular design of the validation module keeps the added complexity manageable and isolated.

AI summary
A vehicle system is disclosed and includes: a transceiver; a vehicle module configured to execute a supervised partially autonomous application (SPAA) at a vehicle; a user interface system configured to receive an input from a user to initiate a supervised remote mode for user presence control during execution of the SPAA; and a user presence module configured, until SPAA operations are ceased or completed, to perform a user presence process including iteratively i) transmitting a challenge request signal from the vehicle to a mobile smart device via the transceiver, ii) based on the challenge request signal, receiving a response signal from the mobile smart device indicating a user response provided to the mobile smart device, iii) based on the response signal, confirming user presence and whether the user response is valid for continued execution of operations of the SPAA, and iv) based on validation of the user response, performing a next operation of the SPAA.
