PROBLEM TO BE SOLVED: To perform appropriate speed change control, in a vehicle having a motor generator made to function as an electric motor or an generator, and an engine and provided with an automatic transmission between these motor generator and engine and driven wheels. SOLUTION: At speed change time of an automatic transmission, so as to change an input rotational speed N1 of the automatic transmission by a speed change time motor control means 140 in accordance with a prescribed target rotational speed N1*, the motor torque TM of a motor generator is feedback controlled. Based on the correction amount ΔTM of this motor torque TM, the duty ratio D3 N of a hydraulic control means (linear solenoid valve or the like) 146 for controlling the initial oil pressure of a hydraulic engaging means and engaged or disengaged at speed change time, is corrected by an engaging adjusting means 142, and stored in a learning map, and the initial oil pressure at speed change time thereafter is changed. Using the output torque T0 of the automatic transmission in place of the input rotational speed N1 . The motor torque TM may be feedback controlled. |
