Charge / discharge control system and control method for hybrid vehicle

摘要

A control center that defines a control range when an abnormality relating to the power storage device 10 occurs in a travel mode in which travel is controlled so that the amount of charge (SOC) of the power storage device mounted on the hybrid vehicle is maintained within a predetermined control range. The value SOCr # is set higher than the normal control center value SOCr set in the vicinity of the SOC management lower limit value, and then charging / discharging of the power storage device is permitted. As a result, when an abnormality occurs at a level where it is not necessary to immediately interrupt charging / discharging of the power storage device, the power storage device can be protected and the vehicle operation accompanied by its use can be continued.
