Vehicle Control Panel Passenger Authentication for Driver Lockout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining which vehicle occupant is using a touchscreen display panel are unreliable and costly, particularly in distinguishing between the driver and passenger, as they often fail to accurately prevent the driver from accessing restricted functions while the vehicle is moving.
Innovation Solution
A two-factor authentication system using a fingerprint interface integrated into the display panel, combined with a detection sensor to ensure the occupant is seated in the passenger seat, allowing only enrolled passenger fingerprints to access restricted functions when the vehicle is in motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If proximity sensors such as ultrasonic detectors are used to detect which occupant is touching the touchscreen, then the system can identify the active user, but the reliability and accuracy of driver-passenger distinction is insufficient
Solution Approach 1:
The patent combines multiple detection methods (proximity sensors, signal modulation devices, and fingerprint sensors) into a unified authentication system. The fingerprint sensor is integrated directly into the touchscreen display panel, creating a merged system that cross-validates occupant identity through both location detection and biometric verification, thereby resolving the reliability and accuracy issues of using单一 detection method
Solution Approach 2:
The fingerprint sensor acts as an intermediary verification layer between the touchscreen interface and the vehicle control system. Instead of relying solely on proximity or signal modulation, the system introduces fingerprint authentication as a mediating step that confirms the occupant's identity before enabling driver-restricted functions, significantly improving distinction reliability
2Measurement precision
If signal modulation devices are used to pass unique signals through occupants to identify seating position, then occupant location can be detected, but system cost and long term reliability deteriorate
Solution Approach 1:
The fingerprint sensor is integrated directly into the touchscreen display panel, allowing the existing touchscreen infrastructure to serve dual purposes: user interface interaction and biometric authentication. This self-service approach eliminates the need for separate, complex signal modulation devices while maintaining accurate seating position and identity detection
Solution Approach 2:
The touchscreen display panel is designed with multi-functionality, serving both as the user interface for vehicle controls and as the substrate for fingerprint sensor integration. This universal design allows a single component to perform multiple functions (display, touch input, and biometric verification), reducing overall system complexity and cost while improving reliability
3Ease of operation
If fingerprint sensors are used to limit access to touchscreen functions, then access control can be implemented, but the system cannot ensure the person is not in the driver seat
Solution Approach 1:
The system implements feedback by continuously monitoring both fingerprint authentication results and occupant seating position data. The control unit cross-references this feedback information to determine whether to enable or disable driver-restricted functions, ensuring that even if a fingerprint matches, the functions remain blocked if the authenticated person is detected in the driver seat
Solution Approach 2:
The system performs preliminary verification by checking occupant seating position before allowing fingerprint authentication to grant access to driver-restricted functions. This preliminary action ensures that the authentication context is valid (passenger seat occupancy) before proceeding with fingerprint verification, thereby preventing driver access even with valid fingerprints

AI summary
The invention is an apparatus used for providing control of functions of a vehicle in response to touch commands of an authorized passenger. The functions for which the authorized passenger is provided control are disallowed to the driver when the vehicle is moving. The passenger is authorized with two-factor authentication. The first of the two factors is the fingerprint of the passenger which is enrolled before vehicle movement. The second factor is the location of the passenger. The first factor is used when an occupant attempts to control disallowed functions. The second factor is used when an occupant attempts to enroll a fingerprint. A display panel displays a prompt to enroll a fingerprint before vehicle movement, uses a fingerprint interface to enroll an original fingerprint, and instantaneously captures fingerprints of those attempting to control disallowed functions and compares them to enrolled fingerprints.
