  "textContent": "When an amount of particulate matters (PM) collected by a gasoline particulate filter (GPF) increases, a control processing unit (CPU) of an engine electronic control unit (ENG ECU) stops combustion control of some cylinders and executes a regeneration process to cause air-fuel ratios of air-fuel mixtures in the remaining cylinders to be richer than a stoichiometric air-fuel ratio. A CPU of a hybrid electric vehicle electronic control unit (HV ECU) increases a target rotation speed of an internal combustion engine when the regeneration process is executed. When executing the regeneration process, the CPU increases a filling efficiency of the internal combustion engine.",
