PTID Ignition Interlock for Passenger and Time Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ignition interlock systems fail to monitor and enforce compliance with driving licensure restrictions, such as passenger limits and time-of-day restrictions, beyond sobriety and cell phone usage, which are essential for ensuring safe and legal vehicle operation, especially for new drivers and those with specific licensure conditions.
Innovation Solution
A Presence of Passenger and Time Ignition Interlock Device (PTID) system that uses sensors to detect the presence of passengers and monitor time-related restrictions, integrating with a system controller to enforce operational compliance by restricting vehicle startup if restrictions are not met, employing infrared sensors and a user interface for configuration and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ignition interlock systems are used, then sobriety monitoring is achieved, but compliance with passenger limits and time-of-day restrictions cannot be monitored
Solution Approach 1:
The system integrates multiple monitoring functions including sobriety detection, passenger presence detection via infrared sensors, time-of-day restriction enforcement, and seat belt monitoring into a single unified ignition interlock system. This allows the device to enforce comprehensive driving licensure restrictions across multiple parameters simultaneously, resolving the contradiction by making the system multi-functional rather than adding separate devices.
Solution Approach 2:
The patent combines previously separate monitoring functions (sobriety testing, passenger detection, time restriction enforcement) into one integrated system that controls vehicle ignition through a single controller. This merging approach achieves versatile compliance monitoring while avoiding the complexity of multiple independent systems operating separately.
2Reliability
If multiple sensors and monitoring functions are added to enforce comprehensive restrictions, then compliance monitoring capability is improved, but device complexity increases
Solution Approach 1:
The system divides compliance monitoring into distinct functional modules: sobriety detection module, infrared passenger detection module, time-of-day restriction module, and seat belt monitoring module. Each module operates independently but feeds into a central controller that makes the final ignition decision. This segmentation allows reliable multi-parameter monitoring while keeping individual components manageable and the system maintainable.
Solution Approach 2:
A central system controller acts as an intermediary that receives inputs from multiple sensors (breathalyzer, infrared sensors, time clock, seat belt sensors) and processes them according to stored restriction parameters. This intermediary approach allows the system to handle complex multi-parameter compliance checking without requiring direct complex interconnections between all sensor components.
3Adaptability or versatility
If infrared sensors and additional monitoring components are integrated, then passenger and time restriction compliance is enforced, but installation complexity increases
Solution Approach 1:
The system includes automatic configuration capabilities where the controller can self-program restriction parameters based on driver's license data retrieved through OBD-II connection. The infrared sensors are pre-positioned to automatically detect passenger presence without requiring manual calibration. This self-service approach reduces installation complexity by eliminating manual programming and calibration steps.
Solution Approach 2:
Restriction parameters are pre-stored in the system memory before operation begins. The system performs preliminary configuration by automatically retrieving driver license information and programming appropriate restrictions (passenger limits, time windows, speed limits) before the vehicle is driven. This preliminary action simplifies installation by eliminating the need for complex setup procedures during installation.

AI summary
A device, system and method for establishing, determining compliance and ongoing monitoring of a user in the operation of a machine based on predetermined restrictions. The system is useful for a motor vehicle and, more particularly, to comply with user restrictions in teen driving, the presence of passengers, time of day, curfew, range and location, speed, sobriety and the like, An ignition interlock is engaged if one or more sensors that monitor the presence of the vehicle operator, passengers inside the vehicle compartment, and other operational compliance parameters established for the vehicle is out of compliance, and disengaged if compliance is verified.
