The present invention provides a vehicle driving support system capable of reducing a data processing load in the production of a personal driver model and a general driver model. The vehicle drivingsupport system includes: a general driver model learning unit (1) that learns a general driver model (Ma) for applying the plurality of drivers based on driving data of a plurality of drivers; a individual driver model learning unit (3) learns the individual driver model (Mb) inherent to the specific driver based on the driving data of the specific driver; a first synchronization engine (40) obtains the first data conversion process by performing the first data conversion process on the driving data of the specific driver received by the individual driver model learning unit (3) from the specific driver (A) of the specific driver. The driving data is supplied to the above-described general driver model learning unit.
