Driver Status Key System for Selective Safety Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles lack the ability to prevent secondary drivers from disabling safety and notification features, posing a risk as primary drivers may not ensure these features remain enabled during vehicle operation.
Innovation Solution
A system and method that differentiate between primary and secondary drivers using unique keys with embedded RFID tags, allowing the primary driver to selectively enable or disable safety and notification features based on the driver's status, thereby preventing secondary drivers from disabling critical safety features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple drivers share the same vehicle with conventional key systems, then the vehicle can be accessed and operated by different drivers, but safety and notification features can be inadvertently disabled by secondary drivers
Solution Approach 1:
The system segments driver access rights by assigning different key types (primary and secondary keys) with distinct authorization levels. Primary keys grant full control over safety features, while secondary keys provide limited access. This segmentation resolves the contradiction by allowing multiple drivers to access the vehicle while preventing secondary drivers from disabling safety features, thus maintaining both access flexibility and safety feature reliability.
2Reliability
If safety and notification features are enabled by the primary driver, then safety monitoring and warnings are provided, but the teenager may disable these features without the parent's knowledge
Solution Approach 1:
The system applies local quality by granting different control permissions to different drivers based on their key type. Secondary drivers receive restricted permissions that prevent them from disabling safety features, while primary drivers retain full control. This resolves the contradiction by maintaining safety feature reliability through restricted access while preserving ease of operation for authorized primary drivers who need full control capabilities.
3Ease of operation
If the vehicle provides full control access to all drivers, then each driver can customize safety features according to their needs, but secondary drivers may disable features the primary driver wants to remain enabled
Solution Approach 1:
The system implements dynamic control permissions that change based on the inserted key type. When a secondary key is detected, the system dynamically restricts access to safety feature controls. When a primary key is detected, full customization capabilities are restored. This dynamic approach resolves the contradiction by allowing customization freedom for primary drivers while maintaining safety feature persistence through automated permission changes based on driver identity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures that safety features such as seatbelt reminders, collision warnings, and stability control remain operational when the primary driver is not present, enhancing safety by maintaining feature functionality regardless of the driver's status.
Implementation Method 1
The key ignition device is positioned on each of the primary key and the secondary key and is configured to generate a driver status signal indicative of whether the driver is at least one of the primary driver and the secondary driver
Data Source
AI summary
Primary and secondary keys are adapted to be associated to primary and secondary drivers. A key ignition device is positioned on each of the primary and secondary keys and is configured to generate a driver status signal indicative of whether the driver the primary driver or the secondary driver. A controller is operably coupled to the key ignition device. The controller is adapted to determine whether the driver is the primary driver or the secondary driver. The controller is adapted to generate a position notification signal indicative of the position of the object with respect to the vehicle. The controller is adapted to notify the primary and secondary drivers of the position of the object. The controller is adapted to selectively control the operation of generating the position notification signals based on whether the driver is the primary driver or the secondary driver.
