AI Technical Summary
Existing remote monitoring systems cannot accurately identify the regeneration status of diesel particulate filters, leading to biases in the assessment of vehicle emissions pollutants.
By acquiring exhaust temperature data of the vehicle within a preset time period, deep learning methods or box plot statistics are used to identify the lower limit of the regeneration temperature, and the lower limit of the regeneration temperature is adjusted based on the maximum exhaust temperature to set the temperature threshold for regeneration conditions and identify the regeneration conditions.
It enables accurate identification of the regeneration condition of diesel vehicle particulate filters, eliminates the bias of the regeneration condition on the assessment results of gaseous pollutants, improves the accuracy of the assessment, and can detect whether the particulate filter has malfunctioned.
