Abstract
A vehicle includes a first motor generator that generates electric power using power of an engine, a battery, and a second motor generator that is connected to drive wheels and is driven by electric power supplied from the battery and the first motor generator. An ECU of the vehicle drives the first motor generator as an electric motor with a regenerative electric power, executes a braking control, in which a load of the first motor generator functions as the engine, when an SOC is equal to or more than a threshold value of a waste electric-power start, and changes the threshold of the waste electric-power start based on a running condition of the hybrid vehicle.
Claims10
A control device for a hybrid vehicle including an internal combustion engine, a first motor generator that generates electric power using power of the internal combustion engine, a battery, and a second motor generator that is connected to drive wheels and is driven by electric power supplied from at least one of the battery and the first motor generator, the battery being chargeable with regenerative electric power obtained by operating the second motor generator as a generator during braking of the drive wheels, the control device being configured to:
- drive the first motor generator as an electric motor with the regenerative electric power;
- execute a braking control, in which a load of the first motor generator functions as the internal combustion engine, when a variable representing a state of charge of the battery according to high and low of a value is equal to or more than a predetermined value;
- and
- change the predetermined value based on a running condition of the hybrid vehicle.
