Abstract:
1. A hybrid vehicle including an engine and a motor capable of generating power as a source of power, in which power from at least one of said engine and said motor is transmitted to an output shaft via a torque converter provided with a lock-up clutch and a transmission to be used as a driving force for the vehicle, and a force input through wheels during a deceleration mode of the vehicle is transmitted to said motor via said torque converter and said transmission so that a regenerative operation is carried out by said motor to convert deceleration energy into regenerative energy, said hybrid vehicle comprising: a throttle opening degree detection unit which detects an opening degree of said throttle; a lock-up clutch engaging state determination unit which determines a an engaged state of said lock-up clutch; a lock-up clutch engagement control unit which controls an engagement and non-engagement of said lock-up clutch; a transmission input shaft revolution rate detection unit which detects a revolution rate of an input shaft of said transmission; a motor revolution rate detection unit which detects a revolution rate of said motor; and a motor control unit which drives said motor based on a revolution rate as a target value, wherein, when said throttle opening degree detection unit detects a completely closed state of said throttle, said motor control unit carries out a synchronizing control in which the revolution rate of said motor is controlled so as to be synchronized with the revolution rate of said input shaft of said transmission, which is detected by said transmission input shaft revolution rate detection unit, and said lock-up clutch engagement control unit controls said lock-up clutch so as to be engaged regardless of an engaged state of said lock-up clutch determined by said lock-up clutch engaging state determination unit.
