Problems solved by technology

[0007] Therefore, if the control of the characteristics of each intake valve according to 2005-299594A is applied only to the hybrid vehicle, the operating characteristics of each intake valve are uniformly set so that the reduction is fully obtained at the automatic stop of the internal combustion engine. Pressure, so there is concern that the acceleration performance of the vehicle will be reduced when the internal combustion engine is started

Abstract

A hybrid vehicle includes a rotary electric machine, an internal combustion engine, and a controller. The rotary electric machine is configured to generate driving force for the hybrid vehicle. The internal combustion engine includes a variable valve actuating device configured to change an operation characteristic of an intake valve. The controller is configured to control travel of the vehicle by selectively applying one of a first driving mode and a second driving mode. The controller is configured to control the variable valve actuating device such that at least one of a valve lift of the intake valve and a valve operating angle of the intake valve at start-up of the internal combustion engine when the first driving mode is selected is smaller than the corresponding at least one of the valve lift of the intake valve and the valve operating angle of the intake valve at start-up of the internal combustion engine when the second driving mode is selected. The start-up frequency of the internal combustion engine in a start-up condition in the second driving mode is higher than the start-up frequency of the internal combustion engine in the start-up condition in the first driving mode. The start-up condition is a condition for starting up the internal combustion engine in a stopped state.

Description

technical field [0001] The present invention relates to a hybrid vehicle, a controller for the hybrid vehicle, and a control method for the hybrid vehicle, and more particularly, to a variable valve actuation device including a variable valve actuation device for changing the operating characteristics of an intake valve A hybrid vehicle with an internal combustion engine, a controller for the hybrid vehicle, and a control method for the hybrid vehicle. Background technique [0002] An internal combustion engine is known which includes a variable valve actuation device capable of changing the operating characteristics of an intake valve. There is also known a variable valve actuating device capable of changing at least one of a valve lift and a valve operating angle of an intake valve as such a variable valve actuating device (see No. 2005 - Japanese Patent Application Publication No. 299594 (JP2005-299594A), Japanese Patent Application Publication No. 2004-183610 (JP2004-18...
