The invention provides a method for inhibiting data drifting in a vehicle positioning process. The method comprises the following steps: A, judging that whether a vehicle is in a running state or a stopped state; B, if the judging result is that the vehicle is in the stopped state, inhibiting the data drifting, and if the judging result is that the vehicle is in the running state, not inhibiting the data drifting, wherein the vehicle comprises an engine and an automobile storage battery, and the engine is connected with the automobile storage battery. The method for judging whether the vehicle is in the running state or not is to judging whether the vehicle is in the running state or the stopped state according to a voltage value of the automobile storage battery. Whether the vehicle is in the running state or the stopped state is judged according to the voltage value of the automobile storage battery and an instrument platform decorative plate does not need to be detached, and the safety of an ignition switch is prevented from being reduced; whether the vehicle is in the driving state or not can be accurately judged without the need of judging whether the vehicle is in the running state or not according to high and low electric levels of an ignition wire, and the data drifting can be accurately corrected. The invention further provides a control device of the data drifting in the corresponding vehicle positioning process.
