Automatic vehicle driving system

The present invention relates to an automatic vehicle driving system and, more particularly, to an automatic vehicle driving system which enables a vehicle to be automatically driven to a destination by controlling the vehicle in consideration of signals of traffic lights and surrounding vehicles or objects when a user sets a destination in a navigation device. To this end, the present invention comprises: a mapping module which receives route information set by a navigation device installed in a vehicle, and which converts distances, directions and turning angles to survey data so as to set driving lanes; and a driving control module for enabling the vehicle to be driven along the driving lanes set by the mapping module.
