Control apparatus for hybrid vehicle

摘要

A control apparatus for a hybrid vehicle includes: engine starting means for starting an engine when a need for switching to a 4-wheel drive mode has been forecasted, the hybrid vehicle having a series HV drive mode in which the hybrid vehicle is run with a second electric motor, in the released state of a connecting/disconnecting device, while a first electric motor is operated with a drive force of said engine to generate an electric energy, the control apparatus further including, as said engine starting means, series HV drive controlling means for starting said engine and enlarging a series HV drive mode region for running the hybrid vehicle in said series HV drive mode, so as to cover a portion or an entirety of an original EV drive mode region for running the hybrid vehicle in said EV drive mode, when the need for switching to said 4-wheel drive mode has been forecasted.

1. A control apparatus for a hybrid vehicle comprising:
a controller programmed to perform as: an engine starting device that starts an engine when a need for switching to 4-wheel drive mode has been forecasted, wherein, in the 4-wheel drive mode, first drive wheels are driven with at least one of the engine and a first electric motor connected to the engine, in an engaged state of a connecting/disconnecting device, which is disposed (i) between the engine and the first drive wheels and (ii) between the first electric motor and the first drive wheels, in accordance with a vehicle running condition, while second drive wheels are driven with a second electric motor connected to the second drive wheels; and a series Hybrid Vehicle (HV) drive controlling device that starts the engine and increases a series HV drive mode region for running the hybrid vehicle in a series HV drive mode, in which the hybrid vehicle is run with the second electric motor, in the released state of the connecting/disconnecting device, while the first electric motor is operated with a drive force of the engine to generate an electric energy, so as to cover a portion or an entirety of an original Electric Vehicle (EV) drive mode region for running the hybrid vehicle in an EV drive mode, in which the hybrid vehicle is run with only the second electric motor.
