For example, when the blind area early warning signal is a non-emergency state signal, the processor controls the alarm device to give out an audio alarm at a fixed audio frequency, and if the alarm sound only sounds once. When the received blind area early warning signal is an emergency state signal, the host control device judges the emergency level corresponding to the emergency state signal, and determines and adjusts the sound frequency according to the emergency level, for example, when the blind area early warning signal indicates that a target object is close to a vehicle and the probability of collision is high, the emergency level corresponding to the collision signal is also high, the corresponding times of alarming sound are increased, so that the driver alertness is improved, the collision is avoided, and the driving safety is improved. For another example, when the vehicle normally runs, the alarm frequency corresponding to the alarm device is a fixed frequency, and when the vehicle turns, the corresponding alarm frequency is also increased so as to remind the driver to pay attention to the surrounding vehicles and ensure safe turning.
