Abstract: The present invention is proposed to avoid the generation of shocks when the output of an engine is switched with that of an electric motor connected by a clutch. The invention comprises a first electric motor connected mechanically to an engine and a second electrical motor connected mechanically through a clutch to an engine. The drive force is transmitted to the drive wheel through a transmission from the second electric motor. It is decided whether or not to connect the clutch on the basis of driving conditions. When it is decided to connect the clutch, the engine is controlled so that the output of the engine meets the required force. The first electric motor functions as an electric generator so that the rotation speed of the engine reaches a target rotation speed. When the engine is rotating at a target rotation speed, the clutch is connected. In this way, shocks are avoided when the clutch is connected and improved driving performance is realized.

Abstract: A target drive torque is calculated based on a detected value for vehicle speed and a detected value for an accelerator pedal depression amount. A generator torque is calculated for a motor(1,4) based on a battery SOC. An engine(2) is controlled to a torque value which achieves a target drive torque and a generator torque as a target engine torque. The motor(1,4) is controlled to a value which is the difference of a target drive torque and an engine torque estimation value as a target motor torque. In this way, a required generator amount may be achieved under steady-state conditions and it is possible to satisfy charge conditions of the battery(15). In addition, required drive force by the driver can be achieved during transition running and responsive acceleration and deceleration can be performed.

Abstract: A hybrid drive system for a vehicle comprises a first electric motor in driving relationship to at least one driven wheel, a heat engine, a second electric motor in driving connection to the engine, and a clutch to engage and disengage the engine to and from the driven wheel. Immediately after or upon a command to engage the clutch, a controller retrieves, based on a measure of speed of the driven wheel, data of maximum input torque, which the second motor is capable of absorbing from the engine and data of maximum output torque, which the first motor is capable of producing. The controller compares the torque request command with the retrieved data and selects one of a plurality of different protocols for operation of the first and second electric motors and the heat engine.
