Remote Vehicle Function Activation via Key Intermediary Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods cannot safely activate vehicle functions from a distance, as they rely solely on the vehicle key for command transmission, lacking the capability to ensure the vehicle's location and preventing unauthorized operation.
Innovation Solution
A telecommunications device, separate from the vehicle key, establishes communication with the key, retrieves comparative information, and activates the vehicle function only if the information matches, ensuring safety by verifying the key's identity and location.

Engineering Contradiction Analysis
1Length of stationary object
If a telecommunications device is used to activate vehicle functions from a distance, then the activation range is improved, but the safety and authorization verification capability deteriorates
Solution Approach 1:
The key acts as an intermediary device between the telecommunications device and the vehicle. The telecommunications device communicates with the key, which then communicates with the vehicle, enabling remote activation while maintaining security through the key's involvement in the verification process
Solution Approach 2:
The system implements feedback by having the vehicle send back information about its current state and location to the key, which then compares this with stored reference information. This feedback loop enables verification that the vehicle has not been moved to an unauthorized location before activating the function
2Ease of operation
If the vehicle key is mechanically coupled to a radio module for command transmission, then the ease of operation is improved, but the capability to activate functions from large distances deteriorates
Solution Approach 1:
The solution merges two communication systems: the short-range wireless communication between key and vehicle, and the long-range telecommunications network. By combining these systems, the key can transmit commands remotely via the telecommunications device while maintaining secure vehicle communication
Solution Approach 2:
The key is given multiple functions: it serves as both a traditional vehicle access key and as a remote communication endpoint that can receive commands from telecommunications devices. This multi-functionality enables both close-range and long-range activation capabilities
3Ease of operation
If remote activation is enabled without verification, then the ease of operation is improved, but the risk of unauthorized operation increases
Solution Approach 1:
The system performs preliminary verification actions before activation: the vehicle sends current state information to the key, the key compares this with stored reference information, and only after successful verification is the function activated. This preliminary check prevents unauthorized operations
Solution Approach 2:
The system proactively prevents unauthorized operation by implementing verification mechanisms that block activation if the vehicle location or state does not match authorized parameters. This preliminary anti-action stops potential harmful operations before they can occur

AI summary
A method for activating a function of a vehicle, which is associated with a key which wirelessly interchanges data with the vehicle, is carried out with the aid of a telecommunications device which is different from the key. However, the telecommunications device attempts to communicate with the key in order to make the method safe. During communication with the key, an item of information is obtained and is compared with an item of comparative information.
