PURPOSE:To display optimum drive information for arriving at a destination by specifying and displaying a speed, power consumption to become a crossing point of a characteristic formula including a traveling environment as a parameter and a characteristic formula including a distance to the destination and a battery amount to be used to the destination as parameters. CONSTITUTION:First deciding means 15 decides a mathematical formula form of a first characteristic formula for relating corresponding relationship between a speed to be taken by a battery-powered traveling vehicle 1 and power consumption in a present traveling environment. On the other hand, second deciding means 16 decides a mathematical formula form of a second characteristic formula for relating corresponding relationship between a speed of the vehicle 1 which can travel with a battery amount to be used to a destination at a distance to the destination and power consumption. Specifying means 17 specifies both or either one of optimum speed and optimum power consumption to be taken by the vehicle 1 from the two characteristic formulae decided by the means 15, 16. Then, display control means 18 displays the optimum speed, the optimum power consumption specified by the means 17 on display means 19. |
