Emergency brake intelligent control method based on Internet of Vehicles

The invention discloses an emergency brake intelligent control method based on the Internet of Vehicles. The method comprises the steps that a vehicle acquires CAN bus information and sends an emergency brake message outwards when emergency brake occurs; another vehicle receives the emergency brake message, then judges the relevancy of traveling directions of the two vehicles and the front-back position relation between the two vehicles, and calculates the actual distance dis between the two vehicles and collision reaction distance RD if the two vehicles are related and the vehicle is located behind the vehicle sending the emergency message; if RD<dis<100 m, the another vehicle gives out a voice alarm to remind the driver to slow down; if dis<RD, the another vehicle is automatically controlled to brake and slow down to a safe speed. According to the method, efficient and reliable safety warning is guaranteed, energy consumption of vehicular units is reduced at low communication cost and computation overheads, and a simple and efficient emergency brake intelligent control method is provided for an auxiliary traveling safety mechanism of the Internet of Vehicles.
