Abstract: PROBLEM TO BE SOLVED: To set a remaining capacity central value at which significant deterioration of fuel economy and emission can be avoided, even if a mode change-over switch is operated during travel in an EV mode.SOLUTION: A vehicle can travel in either of an EV mode for traveling using only output of a second power generating electric motor MG2, an HV mode for traveling with output of an internal combustion engine 20 added further and making remaining capacity of a battery 64 approach a remaining capacity central value using the output of the internal combustion engine 20, or an HVS mode. After the battery is externally charged, the vehicle travels in the EV mode. At that time, if an EV switch 96 is changed into an off state, the vehicle travels in the HVS mode. If cooling water temperature is lower than a water temperature threshold when starting travel in the HVS mode, an upper limit value of the remaining capacity central value is set to a first value (high side value), and thereafter, if the cooling water temperature becomes higher than the water temperature threshold, an upper limit value of the remaining capacity central value in the HVS mode is set to a second value lower than the first value until a ready-off state is assumed.

Abstract: PROBLEM TO BE SOLVED: To prevent vehicle power performance in engine startup from deteriorating, while protecting overheat of the converter in startup of the engine.SOLUTION: In a vehicle that includes an engine, a motor, a power storage device, and a boost converter, an ECU sets the product of a reference value WOUTbase and a limitation coefficient K to a discharge electric power upper limit value WOUT of a battery. The ECU assumes the limitation coefficient K as 100% when a converter temperature Tc is less than a permissible temperature T0, and when the converter temperature Tc exceeds the permissible temperature T0, decreases the limitation coefficient K to be lower than 100%. When the engine is staring up, the ECU sets a limit value VHt to limit a boost upper limit value of the converter. When the converter temperature Tc is less than a threshold temperature T1 which is lower than the permissible temperature T0, the ECU assumes the limit value VHt as V2, and when the converter temperature Tc is not less than the threshold temperature T1, decreases the limit value VHt to be lower than V2.

Abstract: PROBLEM TO BE SOLVED: To properly control a charged state of a storage device reflecting performance change of an onboard storage device so as not to spoil the operability of an electrically driven vehicle, and engine startability.SOLUTION: The SOC of an energy storage device installed in an electrically driven vehicle is controlled so that the SOC does not fall outside SOC control ranges 151, 152. When an estimated SOC value falls to a lower control limit value SOCl during the running of the vehicle, an electric power generation mechanism installed in the vehicle starts to charge the energy storage device. When there is a possibility of a reduction in the performance of the energy storage device, that is, when the temperature of the energy storage device is low and/or when the energy storage device is deteriorated, the lower control limit value SOCl is increased to a level higher than that in a normal state. As a result, degradation in the drivability of the hybrid vehicle and degradation in the starting ability of the engine, which are due to the short of the electric power output from the energy storage device, can be avoided.
