Abstract: This disclosure relates to a communication method and an apparatus, applied to an internet of vehicles, for example, V2X, LTE-V, and V2V. An in-vehicle apparatus triggers an on-board function for a first vehicle. The first vehicle carries the in-vehicle apparatus. The in-vehicle apparatus checks whether the first vehicle is allowed to use the on-board function on a first road. When the first vehicle is on the first road, the in-vehicle apparatus enables or disables the on-board function based on a check result. In the embodiments of this disclosure, whether to enable a corresponding on-board function may be controlled, so that the on-board function is enabled without depending on a human requirement. In this way, the corresponding on-board function may be controlled to be applied to an appropriate road, to reduce a vehicle accident risk, and a danger to social security.
