Hybrid vehicle

摘要

A hybrid vehicle includes: a charge state calculator which calculates a charge state of an electricity storer; a standard opening and closing device which turns off a contactor when the charge state calculated by the charge state calculator is lower than a standard lower-limit value; and an engine startup opening and closing device which maintains the contactor in an on state when an engine startup signal is input even when the charge state calculated by the charge state calculator is a value for turning off the contactor, wherein the contactor turning-on operation executed by the engine startup opening and closing device is executed when the charge state calculated by the charge state calculator is higher than an engine startup lower-limit value set lower than the standard lower-limit value by a predetermined value.

1. A hybrid vehicle which outputs power generated from an engine and a motor generator to a drive shaft through a power transmitting mechanism, the hybrid vehicle comprising:
an electricity storing means for exchanging power with the motor generator; a contactor which enables or disables a connection between the motor generator and the electricity storing means; a charge state calculation means for calculating a charge state of the electricity storing means; a standard opening and closing means for turning off the contactor when the charge state calculated by the charge state calculation means is lower than a standard lower-limit value; and an engine startup opening and closing means for maintaining the contactor in an on state when an engine startup signal is input, even when the charge state calculated by the charge state calculation means is a value for turning off the contactor by the standard opening and closing means, wherein the contactor turning-on operation executed by the engine startup opening and closing means is executed when the charge state calculated by the charge state calculation means is higher than an engine startup lower-limit value which is lower than the standard lower-limit value by a predetermined value, and the engine is started by the motor generator.
