The invention discloses a vehicle coasting fuel-saving running control method and a vehicle control system. The vehicle coasting fuel-saving running control method comprises steps as follows: S1, whether a vehicle is in a vehicle coasting fuel-saving running mode or not is judged, if the vehicle is not in the vehicle coasting fuel-saving running mode, the process is ended, and otherwise, S2 is performed; S2, the vehicle coasting speed is determined; S3, the vehicle is enabled to coast; S4, whether the acceleration condition is met or not is judged, if the acceleration condition is met, an engine ignites automatically, the vehicle is accelerated to the vehicle coasting speed, and then S3 is performed; if the acceleration condition is not met, S3 is performed. With the adoption of the vehicle intelligent fuel-saving control method, the vehicle runs in the vehicle coasting fuel-saving running mode automatically under the condition that the proper condition is met, besides, complex operation of a driver is not required, so that fuel consumption is reduced, and driving is more comfortable.
