Vehicle Start System Pattern Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle starting systems lack an additional level of authentication to prevent unauthorized vehicle operation, which can lead to theft or misuse.
Innovation Solution
A method that utilizes a powertrain control module communicating with a vehicle bus system and an electronic pattern-entry user interface, such as a smartphone or in-vehicle display, to authenticate a pattern before enabling tractive power to the vehicle's drive wheels, ensuring only authorized users can start the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical keys or simple electronic detection methods are used for vehicle starting, then the ease of operation is improved, but the security against unauthorized operation deteriorates
Solution Approach 1:
The system performs preliminary authentication by requiring the user to enter a pattern code through the electronic interface before the powertrain control module enables tractive power. This preliminary security check prevents unauthorized vehicle operation while maintaining a relatively simple user interaction process.
2Reliability
If pattern authentication is added to the vehicle starting system, then the security is improved, but the device complexity worsens
Solution Approach 1:
The system utilizes the vehicle's existing electronic interface (such as a touchscreen display or keyboard) for pattern entry, making the authentication system work with already-present components. This multi-functional approach adds security without requiring entirely new dedicated hardware for authentication.
Solution Approach 2:
The electronic interface serves as an intermediary between the user and the powertrain control module. Instead of direct key insertion or simple button pressing, the pattern entry interface mediates the authentication process, translating user input into security verification while keeping the overall system architecture relatively simple.
3Adaptability or versatility
If multiple authentication methods are provided (mechanical key, key fob, pattern entry), then the adaptability is improved, but the device complexity worsens
Solution Approach 1:
The vehicle starting system is designed to support multiple authentication methods including mechanical keys, key fobs, and pattern entry through the electronic interface. This multi-functional approach allows the system to adapt to different user preferences and situations while managing complexity through shared underlying architecture.

AI summary
A method for starting a motor vehicle includes recognizing an engine on event of the motor vehicle at a powertrain control module in communication with a vehicle bus system operatively disposed in the motor vehicle. In response to recognizing the engine on event, an authentication request is transmitted from a verification module to a device having an electronic pattern-entry user interface. The method further includes receiving an entered pattern entered on the electronic pattern-entry user interface, and recognizing, by an authentication system, that the entered pattern is an authenticated pattern. In response to the recognizing that the entered pattern is the authenticated pattern, an authenticated engagement command is transmitted to the powertrain control module to instruct the powertrain control module to enter into an engaged state, the engaged state electrically enabling the powertrain control module to provide tractive power to a vehicle drive wheel.
