Hybrid vehicle and method of engine control of hybrid vehicle

In a hybrid vehicle, each of an engine and an MG1 is mechanically coupled to a drive wheel with a planetary gear being interposed. The planetary gear and an MG2 are configured such that motive power output from the planetary gear and motive power output from the MG2 are transmitted to the drive wheel as being combined. The engine includes a turbocharger, an EGR valve, and a WGV. When opening of the EGR valve exceeds first opening, a controller maintains opening of the WGV at second opening or larger.

A hybrid vehicle includes: an internal combustion engine; a rotating electric machine; a planetary gear mechanism to which the internal combustion engine, the rotating electric machine and an output shaft are connected; a catalyst that purifies exhaust gas of the internal combustion engine; and a controller that controls the internal combustion engine and the rotating electric machine. The controller controls the internal combustion engine and the rotating electric machine to perform catalyst temperature control to shift an operating point on a map representing a relationship between rotation speed of the internal combustion engine and torque generated by the internal combustion engine so that the catalyst has a temperature within an appropriate temperature range. Degradation of the catalyst can be suppressed without deteriorating the function of the catalyst.

Control device for hybrid vehicle for limiting supercharger pressure changes due to power limits

It is determined whether chargeable and dischargeable electric power of a battery which is a power storage device are limited. When it is determined that the chargeable and dischargeable electric power of the battery is limited, an electric power balance target value of the battery during gear shifting control in a stepped gear shifting unit which is a mechanical gear shifting mechanism is calculated. A smaller value is calculated as a change rate limit value when the chargeable and dischargeable electric power is small than when the chargeable and dischargeable electric power is great, and the calculated change rate limit value is used to perform gear shifting control in the stepped gear shifting unit.
