A controller for a hybrid vehicle predicts whether necessary discharging electric power from a power storage device which is required to perform downshift in a transmission exceeds upper-limit discharging electric power of the power storage device when downshift in the transmission is performed in a hybrid vehicle travel mode and controls a compressor rotation speed such that a rate of increase of the compressor rotation speed of a supercharger at the time of performing downshift in the transmission increases as the upper-limit discharging electric power decreases when it is predicted that the necessary discharging electric power exceeds the upper-limit discharging electric power.

Controller and control method for hybrid vehicle

In a vehicle condition in which an engine rotation speed is likely to exceed a maximum rotation speed, since supercharging by a supercharger is curbed, it is possible to curb an increase in an engine torque. Even when the engine rotation speed exceeds the maximum rotation speed, the engine rotation speed is made less likely to increase by control of decreasing the engine torque. In a vehicle condition in which the engine rotation speed is less likely to exceed the maximum rotation speed, since a supercharging pressure becomes relatively high, it becomes easier to secure power performance. Accordingly, it is possible to curb a decrease in power performance due to curbing of supercharging and to prevent an engine from falling into a high-rotation state in which the engine rotation speed exceeds the maximum rotation speed.

Control device for hybrid vehicle

A control device of a vehicle includes a power source and a power transmission device, and comprises: a state determining portion determining whether a vehicle state is a state in which a running performance of the vehicle is limited; a drive torque calculating portion calculating a drive torque as a maximum drive torque which the vehicle outputs based on the vehicle state; a remaining running distance calculating portion calculating a remaining distance as a maximum distance for which the vehicle travels based on the vehicle state; a destination setting portion setting a destination of the vehicle based on the drive torque and the remaining distance; and a driving control portion providing an automatic driving control in which acceleration/deceleration and steering are automatically performed based on the destination when it is determined that the vehicle is in a state in which the running performance thereof is limited.

Control device of vehicle

A control device for a vehicle includes an electronic control unit configured to perform an automatic driving control, to determine whether there is a possibility that a start control of an engine and a gear shift control of an automatic transmission are concurrently executed in a future traveling under the automatic driving control, during execution of the automatic driving control, and to first execute one control of the start control of the engine and the gear shift control of the automatic transmission in the future traveling and execute the other control after the one control finishes, when the electronic control unit determines that there is the possibility that the start control of the engine and the gear shift control of the automatic transmission are concurrently executed in the future traveling under the automatic driving control.

Control device for vehicle

While automatic driving control is being performed, traveling in a driving state of a vehicle corresponding to an unconverged region (including an unperformed region and a performed region) is preferentially selected between the traveling in the driving state of the vehicle corresponding to the unconverged region, and traveling in the driving state of the vehicle corresponding to a converged region. As such, learning control that corrects an amount of operation associated with control of the vehicle is performed more easily throughout the entire learning regions regardless of a usage state of the vehicle by a driver. Therefore, it is possible to achieve an appropriate traveling state at an early stage by the learning control that corrects the amount of operation associated with control of the vehicle.

Control device and control method of vehicle

A plug for a vehicle includes: a body portion; a plurality of insertion portions configured to be inserted into a through-hole provided in a housing; and a flange portion having a notch formed on an outer periphery so as to restrict a rotation of the body portion around an axial center. The insertion portions are formed at two positions opposed to each other across a straight line passing through the notch and the axial center and are provided with retaining lugs engageable with the through-hole.
