Problems solved by technology

However, in the hybrid vehicle disclosed in Japanese Patent Application Laid-Open No. 2000-205000, since the engine start / stop threshold is changed uniformly based on the estimation result of the driving situation regardless of the driver's driving characteristics, it may not be possible to realize Driving performance of the driver's driving characteristics
[0006] In particular, in a hybrid vehicle that can use an external power supply (commercial power supply, commercial power supply) to charge the on-board DC power supply, since the area where the engine is stopped and only the electric motor is used is enlarged, it is difficult for a driver who pursues a sense of acceleration. said, it is possible to feel underpowered when accelerating

Abstract

A learning section (110) learns driver's driving characteristics based on an accelerator opening degree signal (ACC) when a curve determination signal (CV) from a navigation device is active and outputs the result of learning to a storage section (120) with the result of learning matched with a user ID (UID) from the navigation device. A threshold change section (130) reads from the storage section (120) a leaning value corresponding to the user ID (UID) and changes, based on the learning value, a switchover threshold used by a travel control section (140). The travel control section (140) switches between travel modes (EV mode, HV mode) based on the result of comparison between traveling power and the switchover threshold.

Description

technical field [0001] The invention relates to a hybrid vehicle equipped with an internal combustion engine and an electric motor as power sources, a control method of the hybrid vehicle, and a computer-readable storage medium storing a program for causing a computer to execute control of the hybrid vehicle. Background technique [0002] In recent years, hybrid vehicles (Hybrid Vehicles) have attracted attention as environmentally friendly vehicles. A hybrid vehicle is an automobile that uses, in addition to a conventional engine, a DC power supply, an inverter, and an electric motor driven by the inverter as power sources. [0003] In such a hybrid vehicle, starting / stopping of the engine is performed according to the running condition of the vehicle. However, if the start / stop of the engine is repeated frequently, the fuel consumption rate (fuel economy) will deteriorate. [0004] Japanese Patent Application Laid-Open No. 2000-205000 discloses a hybrid vehicle capable o...
