The present invention relates to control of application execution, and more particularly, to a method of controlling the execution of the application according to the traveling speed by obtaining a traveling speed of the own vehicle in a vehicle equipped with a device for executing the application.

Recently, the increase of vehicles on the road has caused very large traffic congestion. Although traffic congestion is more serious in large cities, the astronomical rise in land prices requires unacceptable resources to expand the road network. Therefore, as a more practical solution, attempts have been made to use the existing road network as it is, but to efficiently control traffic flow using an artificial intelligence system. As one way, a car-navigation system is used. This was developed.

The most basic function of the vehicle navigation system is to track the location of the vehicle in operation and display it on the road map accurately.The additional function is to provide useful information about traffic conditions on other roads, gas stations, and government offices.

Then, it is determined whether the calculated traveling speed is equal to or greater than a preset value of the vehicle (S220).

As a result of the determination, when the current driving speed is greater than or equal to the preset value, the vehicle operates in the first mode (S230).
