Innovation Solution
A system utilizing a J2534 compliant hardware device with a SAE J1962 OBDII connector, connected via Wi-Fi or Bluetooth, allows communication with vehicle ECUs through a cloud-based server, enabling remote reprogramming and data management, including emissions control and carbon offset tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different diagnostic and reprogramming devices are used for various communication protocols, then compatibility with different vehicle systems is improved, but device complexity and operational efficiency deteriorate
Solution Approach 1:
The patent implements a universal reprogramming device that supports multiple communication protocols (CAN, LIN, FlexRay, Ethernet) through integrated communication interfaces and protocol stacks, allowing a single device to perform diagnostic and reprogramming functions across different vehicle systems without requiring separate specialized tools for each protocol
2Reliability
If multiple specialized reprogramming devices are maintained for different protocols, then protocol-specific performance is improved, but productivity and time efficiency deteriorate
Solution Approach 1:
The patent combines multiple protocol-specific communication interfaces and processing capabilities into a single integrated reprogramming device, merging the functions of what would traditionally require separate tools into one unified system that maintains protocol-specific performance while enabling technicians to work across all vehicle systems with a single device
3Reliability
If traditional local reprogramming methods are used, then data security is improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The patent introduces a cloud-based server as an intermediary between the reprogramming device and the target vehicle system, enabling secure remote reprogramming operations where the server acts as a trusted mediator that authenticates requests, manages data transmission, and maintains security protocols while allowing technicians to perform reprogramming operations remotely without physical access to the vehicle

AI summary
Disclosed are methods, systems, and apparatus for remote reprogramming of an automotive controller using a local device, a client device, a technician device and a system server. The local device is connected to the automotive controller and is wirelessly connected to the client device. The client device is connected to the technician device through a system server. Programming configurations, including firmware, settings, and parameter updates, are selected from a technician device, sent to the system server, and uploaded to the local device.
