STATE OF CHARGE INDICATOR OF HYBRID VEHICLE

摘要

A state of charge indicator includes a first indication unit that provides an indicator display within a predetermined display range including first and second ends, according to an increase/decrease in a state of charge of a battery of a hybrid vehicle. In an EV traveling mode, the first indication unit allows the first and second ends to correspond respectively to an upper limit of a state of charge range directed to the EV traveling mode, and a first threshold that defines switching from the EV traveling mode to an HV traveling mode. In the HV traveling mode, the first indication unit allows the first and second ends to correspond respectively to a second threshold that defines switching from the HV traveling mode to the EV traveling mode, and a lower limit of a state of charge range directed to the HV traveling mode.

1. A state of charge indicator comprising
a first indication unit that provides an indicator display within a predetermined display range including a first end and a second end, in accordance with an increase and a decrease in a state of charge of a battery of a hybrid vehicle, wherein the first indication unit allows, in an EV traveling mode, the first end to correspond to an upper limit of a state of charge range directed to the EV traveling mode, and allows the second end to correspond to a first threshold that defines switching from the EV traveling mode to an HV traveling mode, the EV traveling mode giving priority to driving with sole use of an electric motor, and the HV traveling mode involving driving with combined use of an engine and the electric motor, and controlling charge and discharge of the battery to allow the state of charge to be within a prescribed range, and the first indication unit allows, in the HV traveling mode, the first end to correspond to a second threshold that defines switching from the HV traveling mode to the EV traveling mode, and allows the second end to correspond to a lower limit of an state of charge range directed to the HV traveling mode.
