METHOD OF CONTROLLING REPRODUCTION OF PF FOR VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17840466 titled 'METHOD OF CONTROLLING REPRODUCTION OF PF FOR VEHICLE
Simplified Explanation
The abstract describes a method for determining the reproduction periodicity of a particulate filter (PF) in a vehicle based on the accumulation of particulate matter (PM) and various driving conditions. Here are the key points:
- The method calculates whether the amount of accumulated PM in the PF is at or above a risk level that could cause damage to the PF during reproduction.
- If the accumulated PM is at or above the risk level, a driving condition index is calculated by considering the likelihood of causing PF damage under different driving conditions.
- Additionally, a temperature index is calculated based on the temperature of the PF, and a PM index is calculated based on the quantity of accumulated PM.
- A degradation condition index is then determined by considering the driving condition index, PF temperature, and accumulated PM quantity.
- The reproduction periodicity of the PF is adjusted based on the degradation condition index, potentially increasing or decreasing the frequency of PF reproduction.
Potential applications of this technology:
- Automotive industry: This method can be applied in vehicles equipped with particulate filters to optimize their reproduction periodicity based on real-time data, ensuring efficient and effective filter maintenance.
- Environmental monitoring: The method can be used in monitoring systems to assess the condition of particulate filters in industrial settings, helping to prevent filter damage and maintain optimal performance.
Problems solved by this technology:
- Optimal maintenance: By considering the accumulation of PM and various driving conditions, the method helps determine the appropriate reproduction periodicity for particulate filters, preventing potential damage and ensuring their longevity.
- Efficiency and cost-effectiveness: Adjusting the reproduction periodicity based on real-time data allows for efficient use of resources, reducing unnecessary filter reproductions and associated costs.
Benefits of this technology:
- Enhanced filter performance: By adjusting the reproduction periodicity based on the degradation condition index, the method ensures that particulate filters are reproduced at the right time, maintaining their effectiveness in capturing PM and reducing emissions.
- Extended filter lifespan: By preventing damage caused by excessive PM accumulation, the method helps prolong the lifespan of particulate filters, reducing the need for frequent replacements.
- Cost savings: Optimizing the reproduction periodicity based on real-time data helps minimize unnecessary filter reproductions, resulting in cost savings for vehicle owners and industrial operators.
