Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of automotive systems, driven by innovations in computers, sensors, and communications, has led to vulnerabilities in vehicle control systems, making them susceptible to hacking, which compromises safety as control units are connected via a common data bus, allowing unauthorized access and potential manipulation of control algorithms.
Innovation Solution
Moving vehicle control systems partially to a mobile device, which has integrated security mechanisms, allowing secure data and command transfer between the vehicle and the mobile device through a security device, authenticating users, forming control commands based on user preferences and safety information, and verifying data integrity to ensure secure vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control units are connected to a common data bus to enable simplified access and communication, then ease of operation is improved, but security deteriorates as hackers can connect to the bus and manipulate control algorithms
Solution Approach 1:
A security device is introduced as an intermediary component between the mobile device and the vehicle's control units. This security device authenticates the mobile device and establishes secure communication channels, allowing simplified access while preventing unauthorized hacking attempts on the common data bus.
2Adaptability or versatility
If control algorithms are distributed across multiple control units developed by different groups, then adaptability is improved, but reliability deteriorates due to potential mistakes, omissions, and vulnerabilities
Solution Approach 1:
The security device implements continuous authentication and verification feedback mechanisms. It monitors communication between control units and the mobile device, verifying data integrity and authenticity in real-time, thereby maintaining safety despite distributed control algorithm development.
3Ease of operation
If traditional devices like mobile phones are connected to the vehicle for simplified access, then ease of operation is improved, but security deteriorates as new hacking opportunities arise
Solution Approach 1:
The security device performs preliminary authentication and security verification before allowing the mobile device to access vehicle systems. This preemptive security measure prevents hacking vulnerabilities from being exploited while maintaining ease of operation for authorized users.

AI summary
Disclosed are systems and methods for securely controlling a vehicle using a mobile device. An exemplary method comprises authenticating, by a mobile device, a user attempting to perform commands controlling one or more vehicle systems of a coupled vehicle, retrieving profile information related to the user's preference associated with the coupled vehicle, establishing a connection between the mobile device and a security device of the coupled vehicle, authenticating the mobile device with the security device, forming, by the mobile device, commands to control the one or more vehicle systems based on command forming algorithms, the one or more vehicle systems comprising actuating devices of the vehicle and electronic systems of the vehicle, modifying the formed commands based on the profile information and safety information related to a location of the vehicle and transmitting the formed commands to the one or more vehicle systems via the security device to securely control the vehicle.
