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 calculated by considering the driving condition index, temperature of the PF, and quantity of accumulated PM.
- The reproduction periodicity of the PF is adjusted based on the degradation condition index.
Potential applications of this technology:
- This method can be applied in vehicles equipped with particulate filters to optimize their maintenance and reproduction schedules.
- It can be used in both gasoline and diesel vehicles to monitor and manage the accumulation of particulate matter in the PF.
Problems solved by this technology:
- The method helps prevent damage to the PF by considering the risk level associated with the amount of accumulated PM.
- It addresses the challenge of determining the appropriate reproduction periodicity of the PF based on various factors such as driving conditions and temperature.
Benefits of this technology:
- By adjusting the reproduction periodicity of the PF based on the degradation condition index, the method ensures optimal performance and longevity of the PF.
- It helps reduce maintenance costs by avoiding unnecessary reproductions of the PF.
- The method improves the overall efficiency of the vehicle's emission control system by managing the accumulation of PM effectively.
Original Abstract Submitted
A method includes calculating whether a quantity of the PMs accumulated in a PF is at or above a risk level at which damage to the PF is caused when reproducing the PF, calculating a driving condition index by accumulating a weighting factor for a driving condition under which there is a likelihood of causing the damage to the PF, when the amount of accumulated PMs is at or above the risk level; calculating a temperature index in accordance with a temperature of the PF and a PM index in accordance with the quantity of the accumulated PMs when the quantity of the accumulated PMs is at or above the risk level; calculating a degradation condition index considering the driving condition index, the temperature of the PF, and the quantity of accumulated PMs; and changing a reproduction periodicity of the PF according to the degradation condition index.
