混合动力车辆及混合动力车辆的控制方法
摘要：
EV优先开关(28)被构成为利用者能够要求EV优先模式和HV模式的切换。ECU(26)，在EV优先模式时由EV优先开关(28)要求了向HV模式的切换时，在蓄电装置(16)的SOC低于第一阈值(Sth1)的情况下，将行驶模式向HV模式切换，并且将SOC控制在要求向HV模式的切换时的SOC附近，在SOC为第一阈值(Sth1)以上的情况下，维持EV优先模式。此外，ECU(26)，当SOC达到比第一阈值(Sth1)小的第二阈值(Sth2)时，强制性地将行驶模式向HV模式切换。
摘要（英）：

An EV priority switch (28) is configured so that a user can request for switching between an EV priority mode and an HV mode. When switching from the EV priority mode to the HV priority mode is requested by the EV priority switch (28), an ECU (26) performs control as follows. That is, when SOC of an accumulator device (16) is lower than a first threshold value (Sth1), the travel mode is switched to the HV mode and sets SOC in the vicinity of SOC upon a request to switch to the HV mode. When the SOC is greater than the first threshold value (Sth1), the EV priority mode is maintained. Moreover,when SOC reaches a second threshold value (Sth2) which is smaller than the first threshold value (Sth1), the ECU (26) forcibly switches the travel mode to the HV mode.
