When a drive control operation is set, a vehicle driving system sets a travel speed of a vehicle as a target travel speed, stores it as a set travel speed and starts drive control of the vehicle. When the drive control operation is resumed, the vehicle driving system compares the set travel speed stored in a memory and a recommended speed of a road on which the vehicle is traveling. When the recommended speed is smaller than the set travel speed and a speed limit change flag is kept reset, the vehicle driving system sets the recommended speed as the target travel speed, and restarts the drive control of the vehicle. When the recommended speed is larger than the set travel speed and at the same time the speed limit change flag is kept reset, the vehicle driving system sets the set travel speed as the target travel speed, and restarts the drive control of the vehicle.
