HYBRID VEHICLE AND METHOD FOR CONTROLLING SAME

摘要

A hybrid vehicle (10) is mounted with: a traveling electric motor (300A); a battery device (310) for storing power to be input and output to the traveling electric motor (300A); an engine (100); and a power generation mechanism (300A) for generating the charging power for the battery device (310) by the output of the engine (100). An ECU (400) sets, in a travel mode in which the engine (100) is activated, battery device charging and discharging power for controlling the SOC of the battery device (310) to be within a predetermined range centered on an SOC control target. The output of the engine (100) is set so as to secure the charging and discharging power. In addition, even when the SOC is lower than the SOC control target, according to a required power necessary for a vehicle traveling, the ECU (400) sets the charging and discharging power so that the battery device (310) is discharged to the limit of a predetermined SOC higher than a lower limit SOC.
