Abstract

Provided is a cruise control system and method. A vehicle cruise control system collects state information of components inside and outside a vehicle, state information of a road on which the vehicle is provided, and drive pattern information of a driver of the vehicle, analyzes a mileage amount and an exhaust gas emission amount of the vehicle based on the collected state information of the components, the road state information, and the drive pattern information, calculates a cruise control speed based on the analysis result, and controls the vehicle to run at the cruise control speed.

Claims

1. A cruise control method for a vehicle, comprising:

collecting state information of components inside and outside the vehicle, state information of a road on which the vehicle is provided, and drive pattern information of a driver of the vehicle;

analyzing a mileage amount and an exhaust gas emission amount of the vehicle based on the collected state information of the components, the road state information, and the drive pattern information; and

calculating a cruise control speed based on the analysis result, and controlling the vehicle to run at the cruise control speed.

2. The cruise control method of claim 1, wherein

the controlling includes:

allowing the vehicle to run at the cruise control speed to provide a highest mileage amount that is greater than the vehicle'"'"'s reference mileage amount; and

allowing the vehicle to run at the cruise control speed to provide the lowest exhaust gas emission amount that is less than the vehicle'"'"'s reference exhaust gas emission amount.

3. The cruise control method of claim 1, wherein

state information of the components includes state information of tire and engine oil included to the vehicle.

4. The cruise control method of claim 1, wherein

the road state information includes a green signal remaining time of a signal lamp on the road, and a road type.

5. The cruise control method of claim 1, wherein

the drive pattern information includes a number of idling states and a number of acceleration and deceleration states per time during the vehicle driver'"'"'s ride.

6. The cruise control method of claim 1, wherein

the calculating of a cruise control speed includes

displaying the calculated cruise control speed to the vehicle driver.

7. A cruise control system comprising:

a vehicle state information processing device for formalizing information of a vehicle'"'"'s inner and outer components;

a road state information processing device for formalizing information of a road on which the vehicle is provided;

a drive pattern information processing device for formalizing drive information of a vehicle driver;

an analyzing device for analyzing the vehicle'"'"'s mileage amount and exhaust gas emission amount based on the formalized information; and

a calculating device for calculating a cruise control speed based on the analysis result by the analyzing device, and controlling the vehicle'"'"'s ride based on the cruise control speed.

8. The cruise control system of claim 7, wherein

the vehicle state information processing device includes:

a sensor for sensing states of the components inside or outside the vehicle;

a collector for state information of the vehicle'"'"'s inner and outer components; and

a processor for converting the collected state information of the vehicle'"'"'s inner and outer components into a formalized format.

9. The cruise control system of claim 7, wherein

the road state information processing device includes:

a sensor for sensing a state of the road on which the vehicle is currently provided;

a collector for collecting state information of the road; and

a processor for converting the collected state information of the road into a formalized format.

10. The cruise control system of claim 7, wherein

the drive pattern information processing device includes:

a sensor for sensing a drive pattern of the vehicle driver;

a collector for collecting the driver'"'"'s drive pattern information; and

a processor for converting the collected drive pattern information into a formalized format.

11. The cruise control system of claim 7, wherein

the calculating device includes a display for displaying the calculated cruise control speed to the user.

12. The cruise control system of claim 7, wherein

state information of the components includes state information of tires and engine oil included to the vehicle,

the road state information includes a green signal remaining time of a signal lamp on the road and a road type, and

the drive pattern information includes a number of idling states and a number of acceleration and deceleration states per time during the vehicle driver'"'"'s ride.
