Vehicle Mileage Storage Anti-Manipulation via Random ECU Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems are vulnerable to mileage manipulation, as the cluster module and electronic control units can be hacked or replaced, allowing for fraudulent alteration of mileage data, which is crucial for determining vehicle value and authenticity.
Innovation Solution
A vehicle control method that randomly selects an electronic control unit to store mileage data, using a communication gateway to transmit and verify mileage, and generates warnings or Dynamic Traction Control when discrepancies exceed a predetermined error range, preventing unauthorized manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mileage data is stored in a single electronic control unit, then the system is simple and easy to access, but the system becomes vulnerable to manipulation and hacking
Solution Approach 1:
The patent divides the mileage storage function across multiple electronic control units (ECUs) instead of concentrating it in a single unit. The controller randomly selects one ECU from a plurality of ECUs to store the mileage data, creating segmentation that prevents any single point of failure or manipulation while maintaining relatively simple system architecture through random selection rather than complex distributed consensus mechanisms.
2Ease of repair
If the cluster module is easily replaceable for maintenance, then ease of repair is improved, but mileage manipulation becomes possible
Solution Approach 1:
The patent introduces a controller as an intermediary between the cluster module and the electronic control units. This controller acts as a mediator that randomly selects which ECU stores the mileage data and manages the authority to store mileage. This intermediary layer prevents direct access to mileage storage, thereby protecting against manipulation while allowing the cluster to be replaced for maintenance purposes.
3Reliability
If mileage is stored in multiple electronic control units, then manipulation resistance is improved, but system complexity and difficulty of locating storage increases
Solution Approach 1:
The patent implements a dynamic selection mechanism where the controller randomly selects which electronic control unit will store the mileage data. This dynamic approach means the storage location changes or is unpredictable, making it difficult for manipulators to know where to look. The randomness provides anti-manipulation capability while the controller's management keeps the system from becoming overly complex.

AI summary
A vehicle may include: a cluster module to display a mileage; a plurality of electronic control units to store the mileage; and a controller to select at least one electronic control unit that stores the mileage, among the plurality of electronic control unit. It is difficult to know which electronic control unit stores mileage-related data, thereby inhibiting or preventing a mileage manipulation behavior performed while replacing a cluster and an electronic control unit.
