HYBRID VEHICLE CONTROL DEVICE

摘要

A hybrid vehicle control device for a drive system is provided with an engine, a motor and an automatic transmission. The hybrid vehicle control device is configured such that when there is a mode switch request during an EV mode where only the motor is used as a drive source, a shift is made to an HEV mode where the engine and the motor are used as drive sources. The hybrid vehicle control device is further configured such that if a mode switch request and a downshift request for the automatic transmission (are generated, mode switch control is immediately started first. The configuration is also such that downshift control is started once the rotational speed of the engine has reached a combustion possible rotational speed, and the transmission speed at this time is made to be faster than an ordinary transmission speed.

1. A hybrid vehicle control device for controlling a drive system including an engine, a motor, a first clutch that is interposed between the engine and the motor, and an automatic transmission, the hybrid vehicle control device comprising:
a hybrid control module programmed to shift from an electric vehicle traveling mode where only the motor is a drive source to a hybrid vehicle traveling mode where the engine and the motor are drive sources upon receiving a mode switch request during the electric vehicle traveling mode; the hybrid control module being further programmed to immediately starts a mode switch control, which shifts from the electric vehicle traveling mode to the hybrid vehicle traveling mode by engaging the first clutch and starting the engine, and starts a downshift control once a rotational speed of the engine has reached a combustion possible rotational speed, upon generation of both the mode switch request and a downshift request of the automatic transmission, the hybrid control module being further programmed to comprise a transmission speed control section which sets a transmission speed during the downshift control to be faster than the transmission speed during the downshift control when only a downshift request of the automatic transmission is generated.
