摘要： A vehicle display device is provided in an electric vehicle including a friction brake and includes: a loss energy calculation module that calculates a loss energy released from the electric vehicle on the basis of an actuation state of the friction brake; a consumption calculation module that calculates an energy consumption consumed by the electric vehicle on the basis of the loss energy; a first efficiency calculation module that calculates a first energy efficiency on the basis of a travel distance and an energy consumption in a first period; a second efficiency calculation module that calculates a second energy efficiency on the basis of a travel distance and an energy consumption in a second period shorter than the first period; and a display control module that controls a display content of an onboard display on the basis of an efficiency difference between the first and second energy efficiencies.
