TURBINE TORQUE-CALCULATING DEVICE OF TORQUE CONVERTER

Title:

TURBINE TORQUE-CALCULATING DEVICE OF TORQUE CONVERTER

Document Type and Number:

Japanese Patent JP2000346730

Kind Code:

A

Abstract:

To accurately calculate the turbine torque of a torque converter.

A turbine torque Ttmap is calculated based on the output characteristics of an engine and the transmission characteristics of a torque converter being measured in a steady state. In a transition state, a correction parameter that is predetermined corresponding to the transition state is read from a correction parameter storage part 18 by a turbine torque correction part 16, the correction parameter is applied to a specific correction function, and the turbine torque Ttmap is corrected.
