Embodiment

[0028] A self-coordinated vehicle passing method at a non-signal-controlled intersection based on location sharing, including the following steps:

[0029] Positioning step: Configure a vehicle monitoring system at the intersection without signal control, and install a vehicle-mounted positioning terminal on the vehicle. The vehicle-mounted positioning terminal is used to realize real-time positioning of the vehicle's position and running track through satellites and communication networks. The vehicle-mounted positioning terminal can use the terminal positioned by the Beidou system. The refresh rate of the existing Beidou module is generally 1Hz. In order to ensure the accuracy, the Beidou module that can reach 50Hz is selected in this implementation. For the vehicle monitoring system, we choose a PC with an i7 processor, which is equipped with a wireless network card.

[0030] Intersection network establishment steps: When a vehicle enters the monitoring area of ​​the vehic...

Abstract

The invention belongs to the technical field of autonomous vehicle coordinated operation. The invention, in view of a traffic conflict problem generated when unmanned vehicles pass by an unmanned intersection, specifically discloses a unsignalized intersection vehicle self-collaborative passing method based on position sharing. The method includes the following steps: configuring a vehicle position real-time monitoring system at a unsignalized intersection; enabling an onboard positioning terminal to share approaching vehicle positions and travelling loci in real time by using a satellite and communication network; and calculating, by a cloud computing platform, the travelling loci of vehicles entering a detection area and a conflict with the approaching vehicles in real time according to intersection monitored data, and enabling vehicles at entrance lanes to pass by the intersection without conflicts.

Description

technical field [0001] The invention relates to the technical field of coordinated operation of automatic driving vehicles, in particular to a self-coordinated vehicle passing method at a non-signal-controlled intersection based on location sharing. Background technique [0002] Self-driving vehicles (Autonomous vehicles; Self-piloting automobile), also known as unmanned vehicles, computer-driven vehicles, or wheeled mobile robots, are intelligent vehicles that realize unmanned driving through computer systems. The research and development of self-driving car technology has a history of decades in the 20th century, and it has shown a trend of being close to practical application in the early 21st century. For example, Google's self-driving car obtained the first self-driving vehicle in the United States in May 2012 The license is expected to enter the market in 2017. [0003] Self-driving cars rely on artificial intelligence, visual computing, radar, monitoring devices, and...
