Wireless ECU Configuration Update via Remote Write Package
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for updating engine control unit (ECU) configurations are inefficient and inconvenient, requiring physical presence at a service center, leading to vehicle downtime, especially when the vehicle is in use and the operator lacks authorized tools or knowledge.
Innovation Solution
A cloud-connected system that allows authorized users to remotely update ECU parameters by generating a write package, transmitting it over the air, and committing the changes to the ECU's memory when the vehicle is turned off, enabling secure and efficient updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional physical service center method is used to update ECU configuration, then update reliability is ensured through authorized personnel and tools, but vehicle downtime increases and operational convenience deteriorates
Solution Approach 1:
The patent replaces the mechanical/physical system of service personnel traveling to vehicles with a wireless communication system. The ECU configuration update is transmitted via wireless signals (cellular, satellite, or other remote communication channels) directly to the ECU, eliminating the need for physical presence at a service center and thereby reducing vehicle downtime while maintaining update reliability through secure authentication protocols.
Solution Approach 2:
The patent introduces a wireless communication interface and remote server as intermediaries between the service personnel and the ECU. The server acts as a mediator that receives update requests, validates authorization, and transmits configuration data wirelessly to the ECU, enabling remote updates without requiring physical service center visits while ensuring update reliability through centralized authorization management.
2Reliability
If traditional service center method is used, then proper authorization and validation are ensured, but operational convenience and ease of update deteriorates
Solution Approach 1:
The patent enables the ECU and vehicle system to perform self-service configuration updates through wireless communication. The ECU automatically receives, validates, and applies configuration updates transmitted wirelessly without requiring manual intervention from service personnel or the vehicle operator. The system autonomously manages the update process, including authentication and parameter application, thereby improving operational convenience while maintaining authorization validation through embedded security protocols.
3Productivity
If ECU configuration is updated while vehicle is in mission, then operational continuity is maintained, but risk of improper update application increases
Solution Approach 1:
The patent implements preliminary validation and buffering of configuration updates before they are applied to the running ECU. The wireless update system receives and validates configuration parameters in advance, buffers them in memory, and performs authorization checks before application. This preliminary action ensures that only validated updates are applied, reducing the risk of improper update application while maintaining operational continuity through seamless transition to new parameters.
Solution Approach 2:
The patent incorporates feedback mechanisms where the ECU transmits status information and acknowledgment signals back to the remote server during the update process. The system receives confirmation that the ECU is ready for updates, applies parameters with continuous monitoring, and verifies successful application before completing the transmission. This feedback loop ensures update application safety while allowing updates during vehicle operation.

AI summary
Systems, apparatuses, and methods for wirelessly updating electronic control unit configuration can include determining operation parameters to be changed of an electronic control unit of an equipment, and generating a write package including the operating parameters to be changed. The systems, apparatuses, and methods include transmitting the write package to the equipment. The write package causes the electronic control unit to change the operation parameters upon verifying that the operation parameters are applicable to the equipment based on values of the parameters. In response to determining that the operation parameters are not applicable to the equipment, the write package can be discarded.
