Abstract
There is provided a control apparatus for hybrid vehicle. A motor/generator and a drive wheel are connected via a power transmission path. Further, an engine is connected to the power transmission path via a friction clutch. An EV mode using the motor/generator is implemented by disengaging the friction clutch, whereas an HEV mode using the motor/generator and the engine is implemented by engaging the friction clutch. When the engine is started in order to shift to the HEV mode during travel in the EV mode, the engine is rotated by a starter motor, and damping torque Tm2 is output from the motor/generator. Damping torque Tm2′ is then transmitted to the engine via the friction clutch, which is set in a slip condition.
Claims2
A control apparatus for a hybrid vehicle in which a drive wheel is driven using an engine and a travel motor, the control apparatus comprising:
- a starter motor to cause said engine to start rotating;
- a power transmission path to transmit power from said travel motor to said drive wheel;
- a friction clutch provided between said engine and said power transmission path and switched between an engaged condition in which said engine is connected to said power transmission path and a disengaged condition in which said engine is disconnected from said power transmission path;
- and
- a damping controller for controlling said friction clutch to a slip condition so that damping torque is transmitted from said travel motor to said engine when said starter motor is driven in order to start said engine in a motor travel condition in which said travel motor is driven.
