Solution Overview
Problem
Current self-hiring vehicle systems lack efficient and secure control mechanisms for managing vehicle access and status changes, such as unlocking and locking, particularly when using wireless smart key technology.
Innovation Solution
A control device with a wireless smart key system that utilizes a microprogram control unit, radio frequency identification, and relay units to manage power and communication for secure unlocking and locking of vehicles based on a unique identifier stored in a storage unit, allowing for remote control via low-frequency signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wireless smart key system is implemented for self-hiring vehicles, then vehicle access control efficiency is improved, but system security and authorization verification may be compromised
Solution Approach 1:
The patent introduces a control device as an intermediary between the wireless smart key and the vehicle system. This control device receives wireless signals from the smart key, verifies authorization through RF ID cards, and then controls the unlocking/locking relays. This intermediary layer ensures that the wireless communication can be efficiently processed while maintaining security through additional verification mechanisms.
Solution Approach 2:
The system implements self-service functionality where the wireless smart key automatically transmits authorization signals to the control device without requiring manual intervention. The control device then autonomously verifies the RF ID card and executes the unlocking or locking operation, enabling efficient self-hiring vehicle access while maintaining security protocols.
2Ease of operation
If continuous power supply is provided to the wireless smart key, then operational functionality is maintained, but power consumption increases
Solution Approach 1:
The control device implements periodic power supply to the wireless smart key through the power unit and control switches. Instead of continuous power, the system activates power supply only when authorization is needed (during unlocking/locking operations), thereby reducing overall power consumption while maintaining full operational functionality when required.

AI summary
A control system for vehicle hiring includes a control device and a wireless smart key. The control device includes a first microprogram control unit. The wireless smart key includes a second microprogram control unit, a positive electrode and a negative electrode both electronically coupled to the second microprogram control unit. When the first microprogram control unit receives a first sensing signal or a second sensing signal, the first microprogram control unit is electronically coupled to the positive electrode and the negative electrode.
