Vehicle Power Switch Remote Control With Motion-State Lockout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling vehicle power switches lack flexibility and remote management capabilities, particularly in electric vehicle applications where secure and efficient control is essential for both user experience and business management.
Innovation Solution
A method and system that utilize a remote server to control a vehicle's power switch over a network, allowing for remote activation and deactivation of the power switch while ensuring the switch is not operated while the vehicle is in motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a remote server is used to control the power switch over a network, then remote management capability and flexibility are improved, but system complexity increases
Solution Approach 1:
A remote server acts as an intermediary between the user and the vehicle's power switch. The server receives control requests from users via a network, verifies authentication information, and sends corresponding control instructions to the vehicle's control unit. This mediator approach enables remote management capability while keeping the vehicle's on-board system relatively simple, as the complex network communication and authentication logic are handled by the external server rather than the vehicle itself.
2Reliability
If authentication verification is performed before controlling the power switch, then security is improved, but control time increases
Solution Approach 1:
Authentication verification is performed as a preliminary action before the power switch control is executed. The remote server first verifies the authentication information provided by the user, and only after successful verification does it proceed to send the power switch control instruction. This preliminary authentication ensures security by preventing unauthorized access, while the automated verification process minimizes the time added to the control operation.
3Productivity
If the power switch is controlled remotely while the vehicle is stationary, then management efficiency is improved, but safety risk increases if the vehicle is in motion
Solution Approach 1:
The system incorporates feedback by monitoring the vehicle's operational state (whether it is stationary or in motion) before executing remote power switch control. The control unit receives the remote control instruction and determines based on the vehicle's current state whether to execute the instruction. This feedback mechanism ensures that power switch control is only performed when the vehicle is stationary, thereby maintaining safety while preserving management efficiency for legitimate remote operations.

AI summary
A method and a system for controlling a power switch (114) of a vehicle (110) are adapted to be used on the vehicle (110). Firstly, a remote server (120) is utilized to determine whether it is feasible to connect to the vehicle (110) via a network (130). When a result of the determination is positive, the remote server (120) transmits a first instruction, which is used for turning on or off the power switch (114), to the vehicle (110) via the network (130). After the vehicle (110) receives the first instruction, a determination as to whether the vehicle (110) is in a moving state is made. Being in the moving state, the vehicle (110) ignores the first instruction. Not being in the moving state, in response to the first instruction, the vehicle (110) controls the power switch (114) to turn the power switch (114) on or off.
