摘要： PROBLEM TO BE SOLVED: To suppress deterioration of emission while achieving improvement in fuel consumption, in a hybrid vehicle.SOLUTION: When a hybrid vehicle is in a predetermined post-start state where there is no history that an engine is started after starting of a system, cooling water temperature Tw is lower than a threshold Twref, and an electricity storage rate SOC of a battery is not less than a threshold Sref (S310 to S330), a greater value, as compared to when the vehicle is not in the predetermined post-start state, is set as a start threshold Pstart based on the electricity storage rate SOC (S340). Then, the start threshold Pstart is used to perform control so that the vehicle travels with torque required for traveling accompanying intermittent engine operation outputted to a drive shaft. Thereby, when the engine is first started after starting of the system, a range for load operation of the engine is enlarged, deterioration in fuel consumption caused by engine idling operation is suppressed, and engine warm-up is promptly completed to suppress deterioration of emission.

摘要： PROBLEM TO BE SOLVED: To start an internal combustion engine while corresponding to required driving force.
SOLUTION: In a hybrid automobile wherein a first motor, an engine and a driving shaft are connected to the sun gear, carrier and ring gear of a planetary gear mechanism and also a second motor is connected to the driving shaft, when a threshold value Tthr is set (S139) by subtracting a value that a previously set torque Tcr at the time cranking is divided by the gear ratio ρ of the planetary gear mechanism from a maximum torque Tm2max outputting from the second motor, and required torque Tr* is at the threshold value Tthr or more (S140), control is performed so that the engine is cranked and started, and also the required torque Tr* is applied to the driving shaft while canceling reaction on the ring gear side at the time of cranking. The engine is started while taking in consideration torque Tcr at the time of cranking, therefore, insufficient torque outputted from the second motor when cranking the engine may not be caused. As a result, the engine is started while corresponding to the required driving force.

摘要： PROBLEM TO BE SOLVED: To further surely limit the speed of a vehicle at the maximum speed, irrespective of the traveling resistance, in an automobile equipped with a power output device that can output power to a drive shaft which is connected to the vehicle shaft and in the control device of the automobile. SOLUTION: Cruising torque Tcrs, necessary for a vehicle to cruise at a vehicle speed V, is calculated from the relationship between torque outputted to the drive shaft and the acceleration α of the vehicle, when the vehicle speed V from a vehicle speed sensor exceeds a vehicle speed that is lower than the maximum vehicle speed Vmax by a prescribed value K (S110); cruising torque Tcrs0 necessary for the vehicle to cruise at the maximum vehicle speed Vmax is set by adding the difference between traveling resistance R at the vehicle speed V and traveling resistance R0 at the maximum vehicle speed Vmax to the cruising torque Tcrs (S112); a cruising torque limit value Tlim is set so as to approach the cruising torque Tcrs0 as the vehicle speed V approaches the maximum vehicle speed Vmax (S114); and driver request torque Tr* is limited (S116). Since the gradient resistance and the air resistance at the vehicle speed V are contained in the cruising torque Tcrs0, the vehicle speed can further be surely limited, irrespective of the gradient resistance and the air resistance.

摘要： PROBLEM TO BE SOLVED: To prevent a NOx emission amount from increasing at startup after an engine is stopped in a state in which a B range (brake range) or an SSS range (sequential shift range) is selected.SOLUTION: When a B range or an SSS range is selected at previous engine stop, a fuel increase value at current engine startup is increased compared to a case where a shift range at engine stop is other than the B range or the SSS range. Consequently, since a fuel injection amount is increased at startup after an engine is stopped in a state in which the B range or the SSS range is selected, a NOx emission amount can be prevented from increasing at engine startup.
摘要翻译：要解决的问题：在选择B范围（制动范围）或SSS范围（顺序变速范围）的状态下，防止发动机停止后的启动时的NOx排放量增加。解决方案：当B范围或在先前的发动机停止时选择SSS范围，与发动机停止的换档范围不同于B档或SSS档位的情况相比，当前发动机起动时的燃料增加值增加。因此，由于在选择B范围或SSS范围的状态下在发动机停止后的启动时燃料喷射量增加，因此可以防止在发动机起动时NOx排放量增加。
