Abstract: A vehicle includes an engine, a motor, a rotary electric machine, a battery, and an ECU. The ECU is configured to control the rotary electric machine to generate electric power when the engine is started during the motor traveling mode and provide a cranking torque to the engine, the electric power generated by the rotary electric machine increasing as a vehicle speed increases, and determine whether or not to start the engine based on a comparison between a sum of electric power and a value corresponding to electric power acceptable by the battery. The sum of electric power is a sum of first electric power actually input into and output from the battery during the motor traveling mode and second electric power predicted to be generated by the rotary electric machine while the cranking torque is provided to the engine.

Abstract: In motor double-drive mode, a first rotation speed and a second rotation speed as a drive shaft rotation speed are calculated from rotation speeds of motors on the assumption that an engine rotation speed is zero. A state where a difference between the first rotation speed and the second rotation speed is larger than a threshold continues, and, when a malfunction counter becomes larger than a threshold, it is determined that there is a malfunction in a one-way clutch or pinion gears. At a start of the engine, it is determined that there is a malfunction in the one-way clutch when the engine rotation speed is normally increasing, and it is determined that there is a malfunction in the pinion gears when the engine rotation speed is not normally increasing.

Abstract: A vehicle in a first mode consumes a charge amount of a battery. The vehicle in a second mode maintains the charge amount of the battery. An obtaining circuitry obtains, as a first distance, a total distance for which the vehicle has traveled in the first mode. When the vehicle is assumed to have traveled with the first mode preferentially assigned to the travel route separately from the travel plan, an estimating circuitry estimates, as a second distance, a total distance for which the vehicle would have traveled in the first mode. A notifying circuitry notifies the first distance information and the second distance information.

Abstract: A vehicle is provided with an engine, a battery, a second motor generator generating a driving force by using electric power of the battery, and an electronic control unit (ECU) controlling the engine and the second motor generator. The ECU is configured to be capable of executing rotation speed increase control for controlling the rotation speed of the engine so that the sound pressure of the engine is increased in response to an increase in the vehicle speed of the vehicle. In a charge depleting (CD) mode in which the state of charge (SOC) of the battery is consumed, the ECU limits the execution of the rotation speed increase control compared to a charge sustaining (CS) mode in which the SOC is maintained in a predetermined range.

Abstract: An ECU selects a CS mode when an SOC of a power storage device becomes smaller than a threshold value during a CD mode being selected. The ECU allows switching to the CD mode when the SOC exceeds a CD mode allowance SOC threshold value which is greater than the threshold value during the CS mode being selected. When an increase in the SOC is requested by means of an SOC restoration switch, the ECU executes an SOC restoration control. The CD mode allowance SOC threshold value in a case where an increase in the SOC is requested by means of the SOC restoration switch is smaller than the threshold value in a case where an increase in the SOC is not requested by means of the SOC restoration switch.
