Problems solved by technology

[0006] In addition, a hybrid vehicle includes the above-mentioned engine, an electric motor for running, and a mode selection device that selects one running mode from a plurality of running modes based on a user's operation. In a hybrid vehicle, when the mode selector selects the first travel mode as the travel mode, if the first travel mode is used to travel with the power from the electric motor at a stop and the second travel mode is to travel with the rotation of the engine, if the first travel mode is always used as the second travel mode When driving in a driving mode, the opportunity to regenerate the filter cannot be ensured after the rotation of the engine stops

Embodiment

[0031] figure 1 It is a configuration diagram showing a schematic configuration of a hybrid vehicle 20 as an embodiment of the present invention. As shown in the figure, the hybrid vehicle 20 of the embodiment includes an engine 22, a planetary gear 30, electric motors MG1, MG2, inverters 41, 42, a battery 50 as a power storage device, a display 92, and an electronic control unit for hybrid power (hereinafter , referred to as "HVECU")70.

[0032] The engine 22 is configured as an internal combustion engine that uses gasoline, light oil, or the like as fuel to output power. An exhaust purification device 23 and a particulate matter removing filter (hereinafter referred to as “PM filter”) 25 are attached to the exhaust system of the engine 22 . The exhaust purification device 23 is filled with a catalyst 23 a for removing unburned fuel and nitrogen oxides in the exhaust gas. The PM filter 25 is a porous filter made of ceramics, stainless steel, etc., and removes particulate m...

Abstract

There is provided a hybrid vehicle comprising a mode selection device configured to select one drive mode among a plurality of drive modes according to a user's operation. The plurality of drive modesinclude a first drive mode in which the hybrid vehicle is driven with power from a motor with stopping rotation of an engine and a second drive mode in which the hybrid vehicle is driven with rotation of the engine. On satisfaction of filter regeneration conditions that an accumulated amount of particulate matter accumulated on a filter is equal to or greater than a predetermined accumulated amount and that a temperature of the filter is equal to or higher than a predetermined temperature, the hybrid vehicle is driven in the second drive mode even when the first drive mode is selected by themode selection device.

Description

technical field [0001] The present invention relates to a hybrid vehicle, and more specifically, to a hybrid vehicle including a running engine, an electric motor, and a mode selection device equipped with a filter for removing particulate matter in an exhaust system. Background technique [0002] Conventionally, as such a hybrid vehicle, it has been proposed to include an engine equipped with a filter for removing particulate matter in the exhaust system, and a motor generator connected to the output shaft of the engine (for example, refer to Patent Document 1). . In this vehicle, when there is a filter regeneration request and the filter temperature is within the first temperature range, the engine speed is controlled by the motor generator so that the engine speed becomes a predetermined speed while the fuel injection of the engine is stopped. The engine is motored to perform regeneration control for supplying oxygen-containing air to the filter, thereby burning particul...
