ENGINE OPERATION CONTROL DEVICE FOR HYBRID VEHICLE

摘要

An engine operation control device for a hybrid vehicle, including: an engine provided in a vehicle; a power generator that is driven by the engine to generate electric power; a driving battery that is chargeable with electric power supplied from the power generator; and a front motor and a rear motor that drive drive wheels with electric power supplied from the driving battery or the power generator, and allowing a series mode in which the front motor drives front wheels and the rear motor drives rear wheels while the engine is operated at a predetermined set rotational speed to drive the power generator to generate electric power, wherein the set rotational speed is set to increase with decreasing of the atmospheric pressure in a present position of the vehicle in the series mode.

1. An engine operation control device for a hybrid vehicle, comprising:
an engine provided in a vehicle; a power generator that is driven by the engine to generate electric power; a driving battery that is chargeable with electric power supplied from the power generator; a driving motor that drives drive wheels with electric power supplied from the driving battery or electric power supplied from the power generator; a mode switching unit for switching a travel mode of the vehicle to a series mode in which the driving motor drives the drive wheels to cause the vehicle to travel while the engine is operated at a predetermined set rotational speed to cause the power generator to generate electric power; an atmospheric pressure detection unit for detecting atmospheric pressure in a present position of the vehicle; and a setting unit for setting a rotational speed of the engine so that the set rotational speed increases with decreasing of the atmospheric pressure detected by the atmospheric pressure detection unit in the series mode.
