At present, the car early warning methods are mostly whistle and flashing lights. Due to the influence of vehicle distance, vehicle sealing, vehicle interior sound, etc., the driver cannot receive the warning information in time to take corresponding measures. In recent years, some new warning methods have also appeared. For example, the vehicle actively obtains external whistle or flashing lights information, processes it into voice information and broadcasts it in the car. If the broadcast is text information, it cannot give the driver enough stimulation. If the broadcast If the sound is short, it may cause noise pollution to other passengers in the car; there is also a warning method of seat vibration warning, the vehicle uses the proximity sensor to sense the external environment, and the vibration sensor installed under or behind the seat reminds the driver However, this kind of vibration regardless of the approach of external vehicles cannot give the driver detailed enough warning information, and a single vibration method cannot inform the driver of the importance of the warning information, which may cause the driver to feel bored.
