HYBRID VEHICLE CONTROL DEVICE
First Claim
1. A hybrid vehicle control device for a hybrid vehicle, wherein:
- the hybrid vehicle includes a driveline, wherein the driveline includes an engine, a motor, and a belt-type continuously variable transmission;
the belt-type continuously variable transmission includes a primary pulley, a secondary pulley, and a belt, wherein the belt is wound over the primary pulley and the secondary pulley, and configured to be clamped by a primary pulley pressure at the primary pulley and a secondary pulley pressure at the secondary pulley; and
the hybrid vehicle employs an HEV mode and an EV mode as drive modes, wherein the HEV mode employs the engine and the motor as drive sources, and wherein the EV mode employs the motor as a drive source without employing the engine as a drive source;
the hybrid vehicle control device comprising a pulley pressure correction control section configured to determine the primary pulley pressure and the secondary pulley pressure, based on an input torque component inputted to the belt-type continuously variable transmission, and a brake torque correction quantity as an inertia torque correction component, under brake-deceleration;
wherein the pulley pressure correction control section is further configured to set smaller the brake torque correction quantity under brake-deceleration with the EV mode selected than that with the HEV mode selected.

Abstract
An FF hybrid vehicle control device having an HEV mode and an EV mode as drive modes is provided with a CVT control unit (84) for determining primary pulley pressure (Ppri) and secondary pulley pressure (Psec) with which a belt (6c) of a belt-type continuously variable transmission (6) will be clamped on the basis of a torque component inputted to the belt-type continuously variable transmission (6) during brake deceleration, and the corrected amount of brake torque which is an inertia torque correction component. The CVT control unit (84) reduces the corrected amount of brake torque during brake deceleration when EV mode is selected to be less than the corrected amount of brake torque during brake deceleration when HEV mode is selected.
