Vehicle Controller Service Processing with Dynamic IP Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle network technologies, such as CAN and FlexRay-based networks, struggle to support high transmission rates required by telematics and infotainment systems, and implementing Ethernet-based networks is costly and complex, especially when adding new services due to the use of static IP addresses.
Innovation Solution
A service processing device for vehicle controllers that allocates dynamic IP addresses and access point names, allowing new services to be processed without updating the database or routing rule table, even when new applications are installed, by using a routing rule table to match dynamic IP addresses with service groups and deliver data to the corresponding access point names based on load statuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static IP addresses are allocated for services, then network stability is improved, but adaptability to new services deteriorates
Solution Approach 1:
The patent applies dynamics by transitioning from static IP address allocation to dynamic IP address allocation. The controller dynamically assigns IP addresses to services based on their types and current network conditions, allowing the system to adapt to new services without requiring pre-configured static addresses. This resolves the contradiction by maintaining network stability through structured dynamic allocation while improving adaptability to new services.
Solution Approach 2:
The patent changes the parameter of IP address allocation from static to dynamic. By introducing dynamic IP address allocation based on service types and network conditions, the system can accommodate new services flexibly while maintaining stable network operation. The controller modifies allocation parameters according to service requirements, resolving the contradiction between stability and adaptability.
2Speed
If Ethernet-based network is implemented, then transmission rate is improved, but device complexity and cost deteriorate
Solution Approach 1:
The patent segments the network into different service groups based on transmission rate requirements. High-speed services are separated from standard services, allowing the system to implement Ethernet-based high-speed communication only where needed rather than throughout the entire network. This reduces overall complexity and cost while maintaining high transmission rates for critical services.
Solution Approach 2:
The patent applies partial action by implementing Ethernet-based high-speed network only for services that require it, rather than deploying it universally. The controller selectively allocates high-speed network resources based on service type and requirements, reducing implementation complexity and cost while achieving high transmission rates where necessary.
3Measurement precision
If routing rule table is updated for new services, then service processing accuracy is improved, but loss of time deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-defining service groups and their corresponding IP address allocation rules in the controller. When a new service is introduced, the system can immediately apply pre-established allocation patterns without requiring manual database updates or configuration changes. This eliminates time loss while maintaining processing accuracy through structured preliminary rules.
Solution Approach 2:
The patent implements self-service by enabling the controller to automatically allocate IP addresses and manage routing rules for new services without external intervention. The system self-adapts to new services by applying predefined allocation policies, eliminating the need for manual database corrections and reducing time loss while maintaining accurate service processing.

AI summary
Disclosed is a service processing device for a vehicle controller, and a method thereof. The service processing device of a vehicle controller includes a plurality of access point names (APNs) that communicates with a server, and a controller that allocates dynamic internet protocol (IP) addresses for services provided by the vehicle controller and to, when receiving data of a service having a dynamic IP address, deliver the data to an APN corresponding to the dynamic IP address.
