Abstract: Provided is a control device for a vehicle, the vehicle including an internal combustion engine, a generator, a battery, and a motor, in which, in a case where the internal combination engine is in operation under a state in which the internal combustion engine and the drive wheel are not mechanically connected to each other, when exhaust gas recirculation is performed and a number of rotations and a torque of the internal combustion engine are switched from a first state to a second state, and in which the control device determines whether to execute an assistance operation or a non-assistance operation.

Abstract: To provide a vehicle in which an increase or fluctuations in engine vibration or noise during external electric power supply can be suppressed. A vehicle includes an electric power generation device, a battery connected to the electric power generation device via a power line, an external electric power supply device that interconnects the power line and external equipment, and an ECU that controls charging and discharging of the electric power generation device and the battery. The ECU starts an engine and supplies electric power generated by a generator to the battery and the external equipment in a case where a SOC is equal to or less than a use lower limit SOC and supplies the external equipment with electric power from the battery in a case where the SOC exceeds a use upper limit SOC. In addition, the ECU executes fixed point control for controlling the engine and the generator.

Abstract: There is provided a charge controller capable of charging a capacitor while suppressing the progress of deterioration of the capacitor without unnecessary charge/discharge of the capacitor. The charge controller includes a voltage sensor 133 that detects the voltage of a capacitor 101, a current sensor 135 that detects the charge/discharge current of the capacitor 101, a battery ECU 123 that estimates the SOC of the capacitor 101 based on the detected voltage, and a management ECU 117. The management ECU 117 calculates the charge/discharge amount from the start of charging of the capacitor 101 by integrating the charge/discharge currents detected by the current sensor 135 and controls the charging of the capacitor 101 based on the estimated SOC and the calculated charge/discharge amount. The management ECU 117 updates and sets the estimated SOC to an actual use upper limit SOC based on the state characteristics of the capacitor 101.

Abstract: At least one of a state and a storage amount of a battery is detected, and a battery output that can be outputted by the battery is calculated on the basis of it. A state of an electric motor is detected, and at least one of electric motor torque and electric motor output that can be outputted from the electric motor and maximal torque of the electric motor are calculated on the basis of it. A state of an engine is detected, and engine starting torque required to start the engine is calculated on the basis of it. An EV range in which the engine is cut off to be capable of driving with only the electric motor is set up on the basis of the calculated battery output, at least one of the calculated electric motor torque and electric motor output, and the calculated engine starting torque.
