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 abstract describes a method for controlling the line pressure in a double clutch transmission (DCT) by estimating the pressure using a linear regression model. When the estimated pressure reaches a predetermined lower limit, an electric oil pump is activated to maintain the line pressure.
- The method is used in a double clutch transmission (DCT).
- A linear regression model is used to estimate the line pressure.
- The line pressure decreases when the electric oil pump stops.
- State variables of the DCT are used to predict the line pressure change.
- The electric oil pump is driven when the estimated line pressure reaches a lower limit.
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
- Ensuring smooth operation of the transmission
Benefits
- Improved performance and efficiency of the double clutch transmission
- Prevents damage to the transmission components
- Reduces the risk of transmission failure
- Enhances overall driving experience
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.
