Diagnostic Connector Vehicle Wake-Up with Authentication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle diagnostic systems risk battery drain due to uncontrolled use of the Ethernet activation line for waking up the vehicle, which can lead to battery discharge, especially when unauthorized or unauthenticated tools/users activate the vehicle.
Innovation Solution
Implementing a dedicated pin on the diagnostic connector that powers up the vehicle only upon successful authentication and authorization, transitioning to standby or sleep mode on failed authentication, and setting a grace period for authorization, thereby controlling the vehicle's power state to prevent unauthorized access and reduce battery drain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the Ethernet activation line is used to wake up the vehicle without authentication control, then the ease of operation for diagnostic activities is improved, but the battery drain increases and battery life decreases
Solution Approach 1:
An authentication intermediary system is introduced between the Ethernet activation line and the vehicle wake-up function. The system requires authentication credentials to be verified before allowing the vehicle to wake up, preventing unauthorized activation. This mediator controls energy consumption by ensuring only authorized diagnostic tools can trigger wake-up events, thus resolving the contradiction between ease of operation and battery drain.
2Productivity
If the Ethernet activation line wakes up the vehicle without authentication, then the productivity for diagnostic activities is improved, but the reliability of battery performance worsens
Solution Approach 1:
Authentication is performed as a preliminary action before the vehicle wake-up is permitted. The system checks authentication credentials in advance, and only if verification succeeds does it allow the Ethernet activation line to wake up the vehicle. This preliminary control mechanism ensures both productivity (authorized diagnostics can proceed) and reliability (battery is protected from unauthorized drain).
3Loss of energy
If authentication and authorization control is implemented on the Ethernet activation line, then the loss of energy is reduced, but the device complexity increases
Solution Approach 1:
The authentication system is designed to be universal, leveraging existing diagnostic communication protocols and credential verification mechanisms that can be integrated into the vehicle's existing diagnostic infrastructure. By using multi-functional authentication modules that can handle multiple tool types and authorization levels, the system reduces energy loss through controlled wake-up events while minimizing the increase in device complexity through standardized, versatile components.
