Abstract: A vehicle control system, a vehicle control method, and a storage medium are provided. A stopping process stops fuel supply to one or more stopping cylinders and supplies fuel to one or more remaining cylinders during a load operation of an engine. During execution of the stopping process, a compensating process compensates for a decrease in output of the one or more stopping cylinders due to the execution of the stopping process by increasing output generated by combustion in the one or more remaining cylinders. The system control circuit causes, when the engine rotation speed of the engine is the same, the output after being increased by the compensating process to decrease as a shaft torque of the crankshaft of the engine increases.

Abstract: A hybrid vehicle includes an engine, a power storage device, a motor generator that receives electric power from the power storage device to generate travel driving force, and an ECU. The ECU selects one of a CD mode and a CS mode, and switches a traveling mode between EV traveling and HV traveling in accordance with a traveling condition in each of the CD mode and the CS mode. Responsiveness of a vehicle driving torque to an operation of an accelerator pedal is higher in the CD mode than in the CS mode.

Abstract: During EV traveling in a CD mode, an electronic control unit determine that an engine is in a state where the engine is likely to be started when an electric power storage ratio SOC of a battery falls short of a threshold Sref, when a battery temperature Tb of the battery falls short of a threshold Tbref, when an output limit Wout of the battery falls short of a threshold Wref, when a temperature Tmg2 of a motor is higher than a threshold Tmg2ref, and when a torque limit Tm2lim of the motor falls short of a threshold Tm2limref. Then, the electronic control unit set a required torque Tr* by using a map for a CS mode in which the required torque Tr* is set to be lower than in a map for the CD mode.

Abstract: At a time of HV traveling entailing a load operation of an engine in a CD mode, an electronic control unit sets a required torque Tr* by using a map for a CS mode, in which the required torque Tr* is set to be lower than in a map for the CD mode, as at a time of the CS mode. Then, the electronic control unit control the engine and a motor for traveling in accordance with the required torque Tr*. Accordingly, a rise in the required torque Tr* can be suppressed compared to setting of the required torque Tr* using the map for the CD mode and a sense of high-rpm idling attributable to a rise in a rotation speed of the engine can be inhibited from being felt by a driver.

Abstract: An ECU may make a changeover between EV running and HV running in accordance with a running situation in each of a CD mode and a CS mode. A start power threshold of an engine at the time when the CD mode is selected may be larger than the start power threshold at the time when the CS mode is selected. Then, the ECU may change the driving force characteristics of a vehicle depending on whether the CD mode or the CS mode is selected that may result in in the vehicle driving torque for the same vehicle speed and the same accelerator opening degree is larger when the CD mode is selected than when the CS mode is selected.
Abstract translation: 根据CD模式和CS模式中的每一个的运行情况,ECU可以在EV运行和HV运行之间进行切换。 当选择CD模式时,发动机的启动功率阈值可能大于选择CS模式时的启动功率阈值。 然后,ECU可以根据是否选择了CD模式或CS模式来改变车辆的驱动力特性,该CD模式或CS模式可能导致相同车辆速度的车辆驱动转矩和当CD的相同加速器开度较大时 选择模式时,选择CS模式。
