Embodiment

[0038] The emergency braking intelligent control system based on the Internet of Vehicles of the present embodiment includes a GPS module, a CAN bus module, a wireless communication module and a data processing module;

[0039] The GPS module is used to collect the latitude and longitude information and driving direction of the vehicle at a certain frequency;

[0040] The CAN bus module is used to obtain vehicle brake information;

[0041] The wireless communication module is used for data communication between vehicles;

[0042] The data processing module is used for processing and judging the received data, and taking early warning actions or control actions.

[0043] The system obtains the vehicle speed from the controller area network CAN at a fixed frequency (such as 5HZ), and obtains curve information through real-time wireless communication at a fixed frequency (such as 1Hz), and obtains GPS information through the vehicle GPS system at all times, including...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles security, and in particular relates to an intelligent control method for emergency braking based on Internet of Vehicles. Background technique [0002] In my country's economic development and people's lives, road traffic has always played a pivotal role. However, since the beginning of the new century, with the improvement of people's living standards, the number of vehicles in the country has exploded, which has also led to a significant increase in road traffic accidents. The traffic environment in large and medium-sized cities is deteriorating day by day, seriously affecting people's daily life and life and property safety. In order to effectively solve the above problems, Internet of Vehicles technology came into being. The Internet of Vehicles refers to an open mobile network formed between vehicles (vehicles) and between vehicles and roads (vehicles) relying on technologies suc...
