Abstract

The invention relates to a fish streaming based non-signal intersection vehicle-vehicle cooperation control system and belongs to the field of vehicle control. A sensing positioning module of the system comprises an environment sensing portion and a navigation positioning portion and specifically comprises a DGPS positioning device, an inertial navigation system, a radar device and a sensor. A motion control module comprises a motion controller, a driver, an actuator, a transmission part and a controlled part. A wireless communication module consists of a transmitting-receiving device. A human-computer interaction interface comprises a processor, a display unit, an input unit, a communication interface and a data storage unit. A power management and control module comprises a storage battery and a level conversion unit. A route planning module adopts global route planning and is provided with an electronic map. A decision control module comprises a central processing unit, an information processing unit and a storage unit. Compared with the prior art, the fish streaming based non-signal intersection vehicle-vehicle cooperation control system has the advantages of being used for an unmanned vehicle, being provided with a wireless communication module and being high in active safety and road utilization rate.

Description

technical field [0001] The invention belongs to the field of vehicle control, in particular to a vehicle-vehicle cooperative control system at an unsignalized intersection. Background technique [0002] Road intersection is an important node of the road traffic network, where traffic flows from different directions converge, which easily leads to collisions between traffic flows. According to statistics from the Traffic Management Bureau of the Ministry of Public Security, in September 2011, a total of 319,471 road traffic accidents were reported across the country, a year-on-year decrease of 18,442 cases, a decrease of 5.4%. There were 17,442 traffic accidents involving casualties, resulting in 5,138 deaths, 19,214 injuries, and direct property losses of 110 million yuan. Among them, the number of traffic accidents at road intersections accounts for about 30% of the total number of accidents. At present, my country urgently needs to improve the safety of the road system, ...
