TORQUE CONTROL DEVICE FOR VEHICULAR ENGINE

Title:

TORQUE CONTROL DEVICE FOR VEHICULAR ENGINE

Document Type and Number:

Japanese Patent JP2005291174

Kind Code:

A

Abstract:

To suppress learning error in engine torque characteristic and enhance reliability in engine torque control.

A first torque calculating part 10 calculates an estimation torque Tp by using a torque converter characteristic, and a second torque calculating part 20 calculates an estimation torque Te by using the engine torque characteristic. An error learning part 30 learns an error amount of the estimation torque Te with respect to the estimation torque Tp for each engine operational area to calculate an error learning value. At this time, an required air quantity calculating part 40 reflects request torque Tr learned by the error learning part 30, and then calculates required air quantity based on the Tr after the reflection.
