1. A vehicular indicator device for a hybrid vehicle which is provided with vehicle drive power sources in a form of an engine and an electric motor and which is driven in one of a plurality of vehicle drive modes including an EV drive mode, a series HV mode and a parallel HV drive mode that is automatically selected according to a vehicle drive power, said vehicular indicator device being configured to indicate the selected vehicle drive mode and said vehicle drive power, the vehicular indicator device being configured:
(i) to indicate a running state of the hybrid vehicle as represented by said vehicle drive power and said selected vehicle drive mode, in a two-dimensional coordinate system on a display screen, which coordinate system is defined by said vehicle drive power and said selected vehicle drive mode, and (ii) to display, on said display screen, a first figure a state of indication of which changes with a change of said vehicle drive power, and a second figure divided into a plurality of regions corresponding to said plurality of vehicle drive modes, said first figure pointing one of said plurality of regions within said second figure which corresponds to said selected vehicle drive mode, wherein an expected maximum running distance of the hybrid vehicle in each of said plurality of vehicle drive modes is calculated, based on an amount of an electric energy stored in an electric-energy storage device connected to said electric motor such that the electric energy is supplied to and received from said electric motor, and an amount of a remaining fuel to be supplied to said engine, and the calculated expected maximum running distance is indicated in said display screen. |
