Abstract
A driver controller of a hybrid vehicle driven by using an electric motor and an engine that is an internal combustion engine. The drive controller can include a storage unit, a temperature detection unit, an environment information acquiring unit, a power consumption calculation unit, and a vehicle control unit. The storage unit can include a power consumption rate map and a power consumption difference threshold map. The environment information acquiring unit can refer to the power consumption difference threshold map to determine power consumption difference thresholds. The power consumption calculation unit can refer to the power consumption rate map to calculate power consumption of the electric motor. The power consumption difference threshold can be a criterion for changing a drive ratio of the vehicle.
