Abstract
Provided is directed to reduce unnecessary fuel consumption due to unnecessary rapid acceleration when a vehicle drives between intersections, and it is an object to allow for economical driving by reducing the fuel cost, and minimize environmental pollution by minimizing the exhaust gas of vehicle, by providing an economical speed for drivers such that vehicles that have passed through an intersection in accordance with the present traffic light economically drives to the next intersection.
Claims14
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.
A method of informing an economical speed of a vehicle, comprising:
- measuring a time when a vehicle passes an intersection and a passing velocity of the vehicle;
- calculating a distance to a next intersection in the driving course to a destination of the vehicle;
- acquiring a condition information of a traffic signal device at the next intersection at the intersection-passing time, by receiving a traffic signal information transmitted from a traffic information management server or the traffic signal device at the next intersection;
- calculating an allowed passing velocity at which the vehicle can pass the next intersection without waiting for a light, using the condition information of the traffic signal device and the distance to the next intersection;
- and
- calculating a driving velocity for reduction of fuel consumption by receiving information on the amount of fuel consumption to the power of the vehicle and using the information on the amount of fuel consumption to the output, the passing velocity, and the allowed passing velocity, and then outputting the driving velocity.
