Intersection vehicle intelligent cooperative passage method

The invention discloses a no-signal intersection vehicle intelligent cooperative passage method based on a CPS (Cyber-Physical System), aiming to overcome the shortcomings of green light zero passage and low passage efficiency caused by fixed traffic light time control, and lack of information interaction among vehicles in the intersection passage management of prior art. Based on the deep fusion of the 3C (computing, communication and control) technology in a CPS, and supported by the GPS technology, vehicle-vehicle communication technology and speed intelligent control technology, the method is provided and comprises three steps of vehicle passage data acquisition, information processing and communication, and decision control; vehicles close to an intersection continuously obtain the passage information of local vehicles, and perform communication interaction with vehicles in other directions so as to percept surrounding environments in real time, and on the basis, the method performs dynamic decision making and control, i.e., the method analyzes whether the local vehicles and other vehicles exist potential bump risks according to the passage information of surrounding vehicles, cuts the risks, considers vehicle passage priorities, controls speeds and ensures vehicle safe and efficient passage.
