Vehicle Infrastructure State Management via Dynamic Transition Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle infrastructure systems rely on key activation for operational state management, which may not be suitable in future scenarios without a key, and lack flexibility to handle new operational states such as autonomous driving.
Innovation Solution
An infrastructure system that uses input signals from sensors to determine operational states based on transition conditions, with each ECU equipped with a state module to apply relevant state rules and control parameters, allowing units to autonomously switch on or off depending on the state, and introducing new operational states like autonomous driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If key-based activation is used to manage operational states, then the system is simple to implement, but it lacks adaptability for future scenarios without keys and new operational states like autonomous driving
Solution Approach 1:
The patent implements a dynamic state management system where operational states and transition conditions are not fixed but can be configured and modified. The ECU determines operational states based on configurable transition conditions that can adapt to different scenarios including keyless operation and autonomous driving modes, making the system flexible without requiring complete redesign for new use cases
Solution Approach 2:
The patent creates a universal state management framework that handles multiple operational scenarios (manual driving, autonomous driving, key-based, keyless) through a single configurable system. The transition conditions and state rules are designed to be general-purpose, allowing the same infrastructure to support diverse operational modes without requiring separate key management systems for each scenario
2Speed
If all ECUs are kept awake to ensure rapid response, then response time is improved, but energy consumption increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring transition conditions and state rules in the ECU's state module. When a wake-up signal is received, the ECU already has the necessary logic ready to rapidly determine the appropriate operational state and activate relevant functions, enabling fast response without needing to keep all systems continuously powered
Solution Approach 2:
The system uses periodic wake-up signals and state transitions instead of continuous operation. ECUs can remain in low-power states and be periodically awakened based on transition conditions (such as ignition events or autonomous driving mode changes), allowing rapid response when needed while conserving energy during normal operation
3Ease of operation
If key-based operational state management is used, then the system is easy to operate, but it cannot support scenarios without keys or new states like autonomous driving
Solution Approach 1:
The ECU autonomously determines operational states by evaluating transition conditions against current system parameters without requiring external key-based control. The state module automatically applies configured state rules to determine the appropriate operational mode, enabling the system to self-adapt to different scenarios including autonomous driving and keyless operation while maintaining simple operation through automatic state management

AI summary
An electrical infrastructure system and method for a vehicle, comprising several electronic control units (ECU) for one or several functional units (30n) for the vehicle, where the said ECUs are connected through a network (32), the infrastructure system is configured to implement a state map comprising various operational states Sn that the vehicle can adopt. These operational states are connected by one or several transitions Tn, where the transition from one operational state to another depends on predetermined transition conditions being satisfied. The infrastructure system is configured to receive one or several input signals (34) to at least one ECU, comprising parameter values that represent events. The said, at least one, ECU is configured to analyse the said input signals with the aid of the said transition conditions, to determine an operational state, and to make the operational state that has been determined available on the network (32).
