Abstract:
1. An apparatus for informing an economical speed of a vehicle, comprising: a passing time measuring unit that measures an intersection-passing time of a vehicle; a passing velocity measuring unit that measures the passing velocity of the vehicle passing an intersection; a distance calculating unit that calculates the distance to the next intersection in the course of the vehicle to a destination; a traffic signal device condition information acquiring unit that acquires condition information of a traffic signal device at the next intersection at the intersection-passing time; a vehicle condition information acquiring unit that acquires an information on the amount of fuel consumption to the power of the vehicle; a calculating unit that calculates a driving velocity for reduction of fuel consumption, using the distance to the next intersection, condition information of the traffic signal device, information on the amount of fuel consumption to the power of the vehicle, and the passing velocity; and an output unit that outputs the driving velocity.
