Abstract

The present invention relates to a vehicle and a method of controlling a vehicle, wherein an electronic control unit is configured to control an internal combustion engine to delay starting of said internal combustion engine in a first mode than in a second mode when conditions i) and ii) are met , the starting of the internal combustion engine is based on the condition that the required power of the vehicle is greater than a starting threshold. The condition i) is a condition that the drive mode is the first mode, and the condition ii) is a condition that the vehicle demanded power requested by the vehicle is greater than the start threshold. The start threshold value is a value that starts the internal combustion engine that is in a stopped state.

Description

technical field [0001] The present invention relates to a hybrid vehicle equipped with a rotary electric machine and an internal combustion engine and a vehicle control method. Background technique [0002] Japanese Patent Application Publication No. 2010-234872 (JP 2010-234872 A) discloses a hybrid vehicle in which when the vehicle required power is greater than the starting threshold of the internal combustion engine, the internal combustion engine Start inside. [0003] The hybrid vehicle can travel in any one of various driving modes including the vehicle continuously performing motor driving using only the driving motor without maintaining the state of charge (SOC) of the power storage device and a driving mode in which the vehicle runs with the internal combustion engine while maintaining the SOC of the power storage device. In such a hybrid vehicle, in order to secure driving power regardless of the driving mode, the internal combustion engine may be started when th...
