Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle charging systems require complex switching between running and charging modes, and existing security measures complicate the charging process, leading to inefficiencies and potential errors.
Innovation Solution
A vehicle system with a power storage device, charge plug, charging unit, connection detecting unit, authenticating unit, and control unit that allows simplified charging by validating user authentication and shift position, enabling charging without requiring key verification during system startup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security measures (key verification) are implemented for system startup, then vehicle theft prevention is improved, but charging operation complexity increases
Solution Approach 1:
The patent applies dynamics by making the authentication requirement conditional rather than fixed. The control unit dynamically adjusts the authentication behavior based on the operational state: during charging operations, authentication is suspended or simplified, while during normal vehicle operation, full authentication is required. This dynamic adaptation resolves the contradiction by allowing the system to maintain security when needed while simplifying operations when charging.
Solution Approach 2:
The patent changes the parameter of authentication strictness based on the system state. When the charging operation is detected (through detection of charging plug connection or charging mode activation), the authentication parameter is modified to allow charging without full key verification. This parameter change enables the system to balance security requirements with operational simplicity for charging.
2Reliability
If key verification is required for system startup, then security is improved, but charging startup time increases
Solution Approach 1:
The patent applies preliminary action by detecting the charging operation state before requiring full authentication. The control unit monitors for charging conditions (plug connection, charging mode) in advance, and when detected, pre-empts the normal authentication sequence by allowing simplified or skipped authentication. This preliminary detection and conditional bypass reduces the time penalty associated with security measures during charging startup.
3Ease of operation
If charging can start without authentication, then charging operation simplicity is improved, but security risk increases
Solution Approach 1:
The patent applies local quality by creating different authentication requirements for different operational contexts. Instead of a uniform authentication policy, the system implements location-specific (state-specific) authentication: full authentication is required for general vehicle operations, while simplified or no authentication is permitted specifically for charging operations. This localized differentiation allows the system to optimize for charging simplicity without compromising overall security.

AI summary
In response to detection of connection between a power supply outside a vehicle and a charge plug, control device invalidates key verification performed for determining whether a key of a user is regular or not, when a shift position is parking and a parking brake is active. This satisfies system start conditions, and the control device turns on respective relays to start a system, and executes charge control for charging a power storage device from the power supply outside the vehicle.
