LINE PRESSURE CONTROL METHOD FOR DCT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17692003 titled 'LINE PRESSURE CONTROL METHOD FOR DCT
Simplified Explanation
The patent application describes a method for controlling the line pressure in a double clutch transmission (DCT) by estimating the line pressure based on certain variables and driving an electric oil pump when the estimated line pressure reaches a predetermined lower limit.
- The method involves estimating the line pressure in a DCT.
- The line pressure decreases when the electric oil pump stops.
- A linear regression model is used to estimate the line pressure based on state variables of the DCT that affect the line pressure change.
- When the estimated line pressure reaches a predetermined lower limit, the electric oil pump is activated.
Potential Applications
- Automotive industry
- Transmission systems
- Double clutch transmissions
Problems Solved
- Maintaining optimal line pressure in a double clutch transmission
- Preventing line pressure from dropping too low when the electric oil pump stops
Benefits
- Improved control over line pressure in a DCT
- Prevents potential damage to the transmission system
- Enhances overall performance and efficiency of the DCT
Original Abstract Submitted
A line pressure control method for a double clutch transmission (DCT) includes estimating a line pressure, which decreases with stoppage of an electric oil pump, based on a linear regression model using state variables of the DCT that are related to a line pressure change, and driving the electric oil pump when the line pressure estimated based on the linear regression model reaches a predetermined lower limit.
