A display apparatus for vehicle includes a speedometer that measures speed of a vehicle, an eco-drive level determination unit that determines an eco-drive level at driving the vehicle based on a recommended depression amount and an actual depression amount, a determination display portion located inside a peripheral visual field region of the driver, a detail display portion located outside of the peripheral visual field region, and a display control unit that controls display in the determination display portion and the detail display portion. The display control unit performs the following controls of (A) setting the display in the determination display portion to ambient display in which contrast of the outline region is lower than contrast inside the outline region, and (B) changing the ambient display according to the change in the eco-drive level.

Display apparatus for vehicle

A battery capacity meter for a battery includes a controller, a display unit for displaying a present dischargeable absolute capacity of the battery and a display light for displaying a condition of the battery under which the present dischargeable absolute capacity of the battery amounts to a maximum of chargeable absolute capacity of the battery. The present dischargeable absolute capacity and the maximum of chargeable absolute capacity of the battery are calculated on a basis of a charging or discharging current and a temperature of the battery. Since the battery capacity meter can display both of the present dischargeable absolute capacity and the maximum of chargeable absolute capacity under the temperature of the battery at charging, it is possible for a driver to confirm the chargeable absolute capacity as a residual capacity of the battery during using it. Moreover, at charging, it is possible to confirm a condition under which the charging has been completed to the maximum of chargeable capacity determined by the battery temperature at that time thereby to prevent a shortage for the full-charging.
