20090277701 | Hybrid vehicle and travel control method of hybrid vehicle - An SOC target is a control target of a remaining capacity of an accumulation device having a characteristic that the internal loss increases in a low SOC region. The SOC target is set to a first value corresponding to a remaining capacity target upon reaching a predetermined point when the remaining travel distance up to a predetermined point where the accumulation device can be charged from outside has become shorter than a predetermined distance. Thus, the hybrid vehicle can perform EV travel by power consumption of the accumulation device. On the other hand, when the remaining travel distance is not smaller than the predetermined distance Dr, the SOC target is set to a second value in the SOC region where the loss of the accumulation device is smaller than the first value. Thus, it is possible to reduce the power consumption in the hybrid vehicle which performs such a remaining capacity management that the remaining capacity of the accumulation device upon arrival at a predetermined point is a predetermined value. | 11-12-2009 |
