A vehicle driving control device is configured to improve response to driver braking operation and shorten the free running distance. The vehicle driving control device processes an image showing an area ahead of the host vehicle to recognize a preceding vehicle in the host vehicle lane, and then determines whether or not the preceding vehicle is making a sudden lateral movement based on this image processing result. If the vehicle driving control device determines that the preceding vehicle is making a sudden lateral movement, then a preliminary braking force is generated.
