If steering detection is performed by continuously monitoring steering parameters in real-time, then steering failure detection accuracy is improved, but computational complexity and processing requirements increase
Solution Approach 1:
The system applies partial monitoring by focusing detection efforts on critical steering parameters (response time, commanded position vs. actual position) rather than monitoring all possible chassis parameters. The determination module only performs failure analysis when specific conditions are met (e.g., when response time exceeds thresholds or when parameter deviations indicate potential failures), reducing unnecessary computational overhead while maintaining high detection accuracy.
Solution Approach 2:
The system implements feedback mechanisms where the determination module continuously receives steering command parameters and actual steering parameters, compares them against expected values, and adjusts its failure determination logic based on the feedback. This closed-loop approach improves detection accuracy by learning from actual vehicle behavior patterns while keeping processing requirements manageable through efficient feedback utilization.
