The invention provides a control system for a vehicle. The control system for the vehicle comprises an acquiring module, a judging module and a control module. The acquiring module is used for acquiring the rotating speed N of the output end of an engine and the rotating speed N_FTC of the input end of a gearbox in the current sampling period, and acquiring the rotating speed N_old of the output end of the engine and the rotating speed N_FTC_old of the input end of the gearbox in the previous sampling period. The judging module is used for comparing the rotating speed N with the rotating speed N_FTC, and comparing the rotating speed N_old with the rotating speed N_FTC_old. The control module is used for controlling the required torque of the engine to be the preset limited torque when the rotating speed N_old is smaller than or equal to the rotating speed N_FTC_old and the rotating speed N is larger than the rotating speed N_FTC, and controlling the required torque of the engine to gradually rise to the target torque within the first preset time. The control system for the vehicle has the advantages of being capable of effectively lowering the impact noise of a power drive chain of the engine and improving the riding comfort. The invention further provides a control method for the vehicle and the vehicle.
