Vehicle Motor Condition Clearing Through Temporary Torque Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle monitoring systems often incorrectly identify transient conditions as hardware faults, leading to unnecessary interruptions and notifications, which can disrupt vehicle operation and provide inaccurate data to the driver.
Innovation Solution
A system that detects and classifies conditions as clearable via a reset process without impacting vehicle operation, using a torque limit to resolve conditions associated with noise or miscommunication, and maintains operation by masking conditions within a predetermined time interval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the monitoring system detects and reports all conditions as hardware faults, then the system provides comprehensive monitoring coverage, but it causes unnecessary interruptions and spurious notifications that disrupt vehicle operation
Solution Approach 1:
The system applies a predetermined time interval threshold before triggering a fault notification. When a condition is detected, the system waits to see if it persists beyond the threshold period before generating an interrupt or notification to the driver. This preliminary time-based filtering action distinguishes between transient noise and genuine hardware faults, eliminating spurious notifications while maintaining comprehensive monitoring coverage.
2Measurement precision
If the system interrupts vehicle operation to resolve detected conditions, then it ensures accurate fault identification, but it causes unnecessary interruptions that impact vehicle performance and driver experience
Solution Approach 1:
The system dynamically adjusts its response based on the persistence of the detected condition. Instead of immediately interrupting operation upon detecting any condition, the system monitors whether the condition persists beyond a predetermined time interval. This dynamic approach allows the system to maintain high measurement precision by confirming actual faults while preserving vehicle productivity by avoiding interruptions for transient conditions.
3Loss of information
If the system provides immediate notifications for all detected conditions, then it ensures complete information delivery to the driver, but it provides inaccurate data that can mislead the driver about actual vehicle status
Solution Approach 1:
The system uses feedback from time-based monitoring to validate detected conditions before generating notifications. When a condition is initially detected, the system continues monitoring to determine if it persists beyond the predetermined time interval. This feedback mechanism ensures that only confirmed, persistent conditions trigger notifications, providing accurate information to the driver while maintaining complete monitoring of all conditions.
Data Source
AI summary
Condition detection and resolution is provided. A system includes one or more processors of a vehicle, coupled with memory. The one or more processors can detect a condition of a motor of the vehicle. The one or more processors can select an action that reduces an amount of torque of the motor for a time interval. The selection can be based on the condition and a mode of operation of the vehicle. The one or more processors can perform the action to clear the condition of the motor without adjustment of the mode of operation of the vehicle.
