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.
