Title:
CONTROL DEVICE AND CONTROL METHOD FOR HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/008461
Kind Code:
A1
Abstract:
Disclosed is a control device for hybrid vehicles, which comprises: an electric motor; an internal combustion engine; a capacitor for supplying power to the electric motor; a first input shaft that is connected to the motor and is selectively connected to the internal combustion engine via a first connection/disconnection part; a second input shaft that is selectively connected to the internal combustion engine via a second connection/disconnection part; a transmission having an output shaft for outputting power to driven sections; and an air conditioner compressor that is coupled to the first input shaft. When the vehicle is traveling at extremely low speeds using only the power from the electric motor, if the storage state of the capacitor is at or below a predetermined level or the engine speed required by the air conditioner compressor is below a desired engine speed, the transmission is controlled in a manner such that the first connection/disconnection part is connected and the internal combustion engine is started using the power from the electric motor, then the first connection/disconnection part or the second connection/disconnection part is coupled in a state between a completely engaged state or a completely disengaged state to transmit the power from the internal combustion engine to the output shaft. Thus, it is possible to switch to a running mode suited to the storage status of the capacitor when a hybrid vehicle is travelling at extremely low speeds.
