Vehicle Monitoring Controller Reset With Malfunction Data Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring-data processing systems for vehicular camera modules struggle to reliably detect malfunctions while minimizing the possibility of erroneous information being outputted, which can lead to vehicle control malfunctions such as erroneous sudden braking.
Innovation Solution
A monitoring-data processing system with a monitor control apparatus that includes a first controller to retrieve monitoring data, determine malfunctions, and perform a reset task while holding malfunction data in an internal register, thereby reducing the time required for restart and minimizing the output of erroneous information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the controller performs a reset task in response to malfunction determination, then the system can recover from malfunction, but malfunction data may be lost during the reset process
Solution Approach 1:
The first controller stores malfunction data in an internal register before performing the reset task. This preliminary action ensures that malfunction information is preserved and can be analyzed after the reset, allowing the system to recover while maintaining diagnostic capability.
2Loss of information
If the system stores malfunction data externally before reset, then data is preserved, but the restart time is extended
Solution Approach 1:
The patent uses an internal register within the first controller to store malfunction data, rather than external memory. This local storage solution allows data preservation during reset without extending restart time, as the internal register maintains data throughout the reset process without requiring additional read/write operations to external storage.
3Duration of action of moving object
If the controller continues operation without reset, then operational time is maintained, but erroneous information may be outputted
Solution Approach 1:
The system performs a rapid reset operation when malfunction is detected, quickly transitioning through the reset state and restoring normal operation. This rushing through the reset process minimizes the time the system is non-operational while ensuring erroneous information is not output, as the reset clears the malfunction state that would cause erroneous output.
Data Source
AI summary
A monitoring-data processing method is executable by at least one processor included in a monitoring-data processing system that includes a control apparatus that retrieves monitoring data indicative of a surrounding of a vehicle. The monitoring-data processing method includes performing processing of the monitoring data retrieved by the control apparatus, and determining whether there is a malfunction in the monitoring-data processing system. The monitoring-data processing method additionally includes performing, in response to a malfunction determination that there is a malfunction in the monitoring-data processing system, a task of (i) switching the control apparatus to be in a reset state and thereafter (ii) restarting the control apparatus while holding data indicative of the malfunction in an internal storage of the control apparatus.
