Vehicle Identity Validation via Server-Controlled Component Signatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The authenticity of vehicle data is difficult to guarantee, as it is challenging to distinguish between genuine data from a specific vehicle and artificially manipulated data, leading to potential fraud in vehicle valuation, rental, and resale processes.
Innovation Solution
A method involving an off-vehicle server unit transmitting a control command signal to a vehicle's components, which are then operated in a specific manner, and the resulting data is verified by an off-vehicle server unit to authenticate the vehicle's identity, ensuring only the designated vehicle can process the command and thus validate its authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle data is collected from external measurement devices, then data availability for vehicle valuation and diagnostics is improved, but data authenticity and reliability deteriorate due to inability to distinguish genuine data from manipulated data
Solution Approach 1:
The system performs preliminary actions by having the server unit transmit control command signals to the vehicle's components before data collection. These commands trigger specific component operations (seat movement, lighting activation, wiper operation) that create unique operational signatures. This preliminary action ensures that only the genuine vehicle can produce the expected operational responses, thereby guaranteeing data authenticity while maintaining data availability for valuation and diagnostics purposes
2Ease of operation
If simple data collection methods are used, then ease of operation is improved, but measurement precision deteriorates due to inability to validate vehicle identity
Solution Approach 1:
The server unit acts as an intermediary between the external measurement device and the vehicle. It transmits control command signals to the vehicle's control unit and receives operational status signals in return. This intermediary role enables automated vehicle identity validation through component response verification while keeping the external measurement device's operation simple. The system maintains ease of operation by automating the validation process through the server intermediary, thereby achieving both operational simplicity and validation accuracy
3Reliability
If control command signals are transmitted to vehicle components, then vehicle identity validation reliability is improved, but device complexity increases due to additional server unit and communication protocols
Solution Approach 1:
The server unit performs multiple functions: it transmits control command signals to vehicle components, receives operational status signals, validates vehicle identity by comparing responses, and provides a digital certificate. By consolidating these multiple functions into a single server unit, the system achieves high validation reliability without proportionally increasing overall system complexity. The existing vehicle control unit and measurement device also serve multiple purposes, further reducing the need for additional dedicated components

AI summary
The invention comprises a method for validating an identity of a designated functional device (10), such as a vehicle, such a functional device as well as a system to conduct such a method. The method comprises transmitting a control command signal (16) for at least one functional device component (18) to the designated functional device (10) (S1). The designated functional device (10) is operated according to the transmitted control command signal (16) (S2). In the meantime, a request signal (26) is transmitted to an off-functional-device device (28) requesting submission of specific measurement data (30) of a presumed functional device (33) (S3). Once the requested specific measurement data (30) for the presumed functional device (33) is received, this data is evaluated by applying a specific evaluation rule (S4, S5). If the evaluation is successful, it is validated that the presumed functional device (33) is the designated functional device (10) (S6).
