  • Patent number: 9272701
    Abstract: In an electric-mileage learning when a running mode of a plug-in hybrid vehicle is a CD mode, acquisition of information for the electric-mileage learning is not performed in the case where the running mode is changed from the CD mode to a CS mode during one trip even when the running mode is changed to the CD mode afterward. The electric-mileage learning is performed by calculating a trip electric mileage using only information acquired in the CD mode before a change to the CS mode for the first time. This avoids inclusion of an error caused by running on the uphill road in the CS mode in a learned electric mileage even when the running is performed. This enhances the accuracy of the learned electric mileage, thus accurately calculating a possible EV running distance.

  • Patent number: 9254757
    Abstract: On a display, a running power determined in accordance with an accelerator position or the like is displayed. When the hybrid vehicle is controlled in a CS mode, the running power is displayed together with eco-acceleration power greater than a first engine starting power. When the hybrid vehicle is controlled in a CD mode, the running power is displayed together with a second engine starting power in place of the eco-acceleration power. The engine is stopped when the running power is smaller than the first engine starting threshold value in the CS mode. The engine is driven when the running power is equal to or greater than the first engine starting threshold value in the CS mode. The engine is stopped when the running power is smaller than a second engine starting threshold value in the CD mode. The engine is driven when the running power is equal to or greater than the second engine starting threshold value in the CD mode.

  • Publication number: 20160001676
    Abstract: An electrically powered vehicle includes a power storage device, a motor, a limitation control unit, a notification unit, and a changing unit. The motor generates traveling driving power using electric power output from the power storage device. The limitation control unit limits possible output power, which indicates electric power able to be output from the power storage device, based on a load state of the power storage device. The notification unit notifies a warning when the possible output power is smaller than a threshold value for notifying a driver of decrease of the traveling driving power. The changing unit increases, when the load state of the power storage device is high, the threshold value to be larger than the threshold value when the load state of the power storage device is low.

  • Patent number: 9162675
    Abstract: The invention relates to a control device of a hybrid system. The control device selectively performs first and second modes for concomitantly using an EV mode for operating the electric motor (12) with the engine operation being stopped and an HV mode for selectively operating the engine and stopping the engine operation with the electric motor being operated by switching the EV and HV modes according to a predetermined switching condition set such that a proportion of an engine operation time in the first mode is smaller than that in the second mode. When an actual acceleration pedal manipulation amount is smaller than a first manipulation amount, an amount of the hybrid system power increased according to the increasing of the actual acceleration pedal manipulation amount in the first mode is made larger than that in the second mode.
