A speed change controlling device for hybrid vehicles

Title:

A speed change controlling device for hybrid vehicles

Document Type and Number:

Japanese Patent JP6183064

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a hybrid-vehicular transmission control apparatus capable of suppressing deterioration of drivability due to engine inertia torque when a clutch is engaged.SOLUTION: A motor MG is controlled at required motor torque Tmz in consideration of engine inertia torque Tei, by having required motor torque computation parts S21-S29 that computes the engine inertia torque Tei on the basis of vehicle acceleration dω'/dt, vehicle inertia, motor torque Tmz, engine torque Tez, and clutch torque Tcz, during a period between after completion of shift to the next transmission stage and completion of clutch engagement; and computes required-motor torque Tmrz that the motor MG requires for output, on the basis of driver-requiring torque Tdr, the engine inertia torque Tei, and the engine torque Tez or clutch torque Tcz.
