Document Type and Number:
Japanese Patent JP3011068
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress the deterioration in the semi-connection state of a clutch for transferring the output of a power plant including an engine and a motor generator to a drive wheel and to suppress the load fluctuation of the power plant in the semi-connection state. SOLUTION: A semi-connection state detection part 46 for detecting the semi-connection state of a clutch 20 is provided. When the semi-connection state is detected, the addition of torque by a motor generator 14 is prohibited. Or, when torque generated by an engine being obtained by the amount of operation of an acceleration pedal 18 is equal to or more than a specific value, the surplus torque is absorbed by the motor generator 14. Furthermore, when an engine speed deviates from a target value, a torque corresponding to the deviation is added or absorbed by the motor generator 14 and a control is made so that the engine speed quickly converges to the target value.
