Abstract
A control device of a hybrid vehicle minimizes fuel consumption by an internal combustion engine while controlling, for a preset period that substantially corresponds to an update cycle of an instructed fuel consumption change rate, an electrical charge-discharge energy balance of a battery to have a predetermined value, (i) by setting, in a predetermined update cycle, the fuel consumption change rate based on travel pattern information and a target electrical charge-discharge balance and (ii) by setting an engine output power increase/decrease amount based on the instructed fuel consumption change rate and the target drive power.
Claims14
A control apparatus of a hybrid vehicle comprising:
- an engine and a motor generator installed in the vehicle as a power source of the vehicle;
- an electric power storage unit that exchanges an electric power with the motor generator;
- a rate-of-change setting unit that sets, in a predetermined update cycle, a fuel consumption change rate representing a rate of change of a fuel consumption by the engine against a difference between an output power of the engine and a drive power of the vehicle;
- and
- a power adjustment amount setting unit that sets, based on the fuel consumption change rate and a target drive power of the vehicle, an engine output power increase/decrease amount that minimizes the fuel consumption by the engine while controlling, for a preset period, an electrical charge-discharge energy balance of the electric power storage unit to have a predetermined value.
