SHIFT CONTROLLER AND SHIFT CONTROLLING METHOD
First Claim
1. A shift controller for a hybrid vehicle in which:
- an engine and a motor are connected together via a clutch; and
a transmission is placed between the motor and driving wheels,the shift controller comprising;
a first shift controlling unit configured to perform shift control on a basis of at least one of transmission efficiency of the transmission and power generation efficiency of the motor in a case where regeneration is performed with the clutch disengaged during deceleration of the hybrid vehicle; and
a second shift controlling unit configured to perform shift control to make a transmission gear ratio of the transmission smaller than in the shift control performed by the first shift controlling unit in a case where the regeneration is performed with the clutch engaged during the deceleration of the hybrid vehicle.

Abstract
A shift controller controls a transmission for a hybrid vehicle in which: an engine and a motor are connected together via a clutch; and the transmission is placed between the motor and driving wheels. The shift controller has: a first shift controlling unit which performs shift control on a basis of at least one of transmission efficiency of the transmission and power generation efficiency of the motor in a case where regeneration is performed with the clutch disengaged during deceleration of the hybrid vehicle; and a second shift controlling unit which performs shift control to make a transmission gear ratio of the transmission smaller than in the shift control performed by the first shift controlling unit in a case where the regeneration is performed with the clutch engaged during the deceleration of the hybrid vehicle.

10. A shift controlling method for a hybrid vehicle in which:
- an engine and a motor are connected together via a clutch; and
a transmission is placed between the motor and driving wheels,the shift controlling method comprising; a first shift controlling operation of performing shift control on a basis of at least one of transmission efficiency of the transmission and power generation efficiency of the motor in a case where regeneration is performed with the clutch disengaged during deceleration of the hybrid vehicle; and a second shift controlling operation of performing shift control to make a transmission gear ratio of the transmission smaller than in the shift control performed in the first shift controlling operation in a case where the regeneration is performed with the clutch engaged during the deceleration of the hybrid vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
