Abstract

A hybrid regulation controller stores a vehicle speed influence value set in accordance with a vehicle speed, a first threshold value of an accumulated value of the vehicle speed influence value, a second threshold value lower than the first threshold value and an engine start standard vehicle speed and momentarily accumulates the vehicle speed influence value (ST2) during an EV running period (ST1: YES). When the accumulated value is equal to or more than the first threshold value (ST7: YES) and when the accumulated value is equal to or more than the second threshold value (ST3: YES) and thevehicle speed becomes equal to or less than the engine start standard vehicle speed (ST4: YES), an engine is started.

Description

technical field [0001] The present invention relates to a control device of a driving device of a hybrid vehicle and a plug-in hybrid vehicle provided with the control device. More particularly, the present invention relates to a control device of a vehicle drive device installed in a hybrid vehicle having an oil pump driven by an engine output shaft, and a plug-in hybrid vehicle provided with the control device. Background technique [0002] As disclosed in, for example, Patent Documents 1 and 2, a general drive device provided in a hybrid vehicle includes an engine such as a gasoline engine or a diesel engine and an electric motor such as a motor or a motor / generator. Engines and electric motors are combined in various forms, and the number of electric motors used is not limited to one; sometimes multiple electric motors are used. [0003] Patent Documents 1 and 2 disclose hybrid vehicles using two electric motors. In these hybrid vehicles, an engine, a first motor / gener...
