Autonomous Driving Control Apparatus ECU Diagnosis and Alternative Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving in vehicles is hindered by the need for continuous normal operation of multiple electronic control units (ECUs), as safe autonomous driving is only possible when all ECUs are functioning properly, and existing systems lack effective diagnostic and alternative control mechanisms to manage abnormal ECU states without driver intervention.
Innovation Solution
An autonomous driving control apparatus that includes a communication control unit (CCU) to communicate with ECUs and an external server, diagnosing ECU states and providing alternative functions to ensure safe autonomous driving by determining whether autonomous driving is possible and switching to alternative functions if necessary, including prioritization to meet performance targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous driving control is implemented without driver intervention, then automation level is improved, but system reliability deteriorates due to potential ECU abnormalities
Solution Approach 1:
The system performs preliminary diagnosis of ECUs before autonomous driving begins and continuously monitors during operation. The controller proactively identifies abnormal ECUs and determines alternative functions before failures occur, ensuring reliable autonomous driving operation.
Solution Approach 2:
The controller acts as an intermediary between ECUs and the autonomous driving control system. It receives diagnosis information from ECUs, determines alternative functions, and coordinates the switching process, thereby managing the transition from normal to alternative operation modes.
2Reliability
If multiple ECUs are monitored for abnormal states, then system safety is improved, but device complexity increases
Solution Approach 1:
The controller performs multiple functions: it diagnoses ECUs, determines abnormal states, identifies alternative functions, and manages switching operations. This multi-functionality consolidates what would otherwise require separate systems into a single controller, managing complexity while maintaining safety.
Solution Approach 2:
The system uses its own diagnostic capabilities to monitor ECU states and automatically determine alternative functions without external intervention. The autonomous driving control system serves itself by internally managing ECU abnormalities and switching to alternative functions.
3Adaptability or versatility
If alternative functions are implemented for abnormal ECUs, then system adaptability is improved, but device complexity increases
Solution Approach 1:
The system dynamically adjusts its operation by switching between normal functions and alternative functions based on ECU diagnostic results. The controller adapts the autonomous driving control strategy in real-time according to the operational status of ECUs, maintaining functionality under varying conditions.
4Measurement precision
If continuous ECU diagnosis is performed during autonomous driving, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The system performs ECU diagnosis periodically and at key moments (before autonomous driving starts and during operation when abnormalities may occur) rather than continuously at maximum intensity. This periodic monitoring maintains diagnostic accuracy while managing energy consumption during autonomous driving operation.

AI summary
An autonomous driving control apparatus for a vehicle may include: a communication control unit (CCU) configured to communicate with at least one electronic control unit (ECU) included in the vehicle and an external server; and a controller configured to diagnose the at least one ECU, to transmit a result of the diagnosis of the at least one ECU to the external server through the CCU, to receive alternative function information, indicating one or more alternative functions, generated by the external server based on the result of the diagnosis of the at least one ECU, and to perform autonomous driving control of the vehicle using the one or more alternative functions.
