Vehicle Safety Braking Model Based on Cyber-Physical System

Transportation intelligent development has become inevitable, intelligent is the future direction of industrial development, and Cyber-Physical system is an intelligent way to realize. As communication, digital twin, perception and other technologies become more and more mature, the realization of intelligence becomes more and more possible. This paper analyzes the components and system characteristics of each part of the Cyber-Physical system of intelligent vehicles, and constructs an intelligent vehicle model based on the Cyber-Physical system. Simulink module is used as the control decision system to process the data. By simulating the vehicle braking scenario, the basic braking system as well as the improved braking system are evaluated in terms of safety and comfort indexes to judge the system performance. The experimental results show that the improved model built based on the Cyber-Physical system reduces the risk of accidents and realizes the safety control of the vehicle in the multi-vehicle cooperative scenario. Meanwhile, the built simulation can also be optimized for different traffic scenarios.
