Problems solved by technology

The system described in this patent can realize the dynamic planning of traffic routes. When the original navigation route is congested, it can change the navigation route in time and remind the driver. If two cars change the navigation route at the same time, it is likely to cause congestion on another road section

specific Embodiment approach

[0027] Compared with the vehicle-road coordination vehicle navigation system before, the urban vehicle navigation system based on vehicle-road coordination described in the present invention provides navigation for the vehicle by the server located in the traffic management center, and its advantage is that the server can make full use of the urban The road completes the navigation path planning. While providing navigation for vehicles, it can also effectively control the traffic flow of each road, preventing multiple vehicles from entering a certain road section at the same time and causing traffic congestion on this road section. When the server provides navigation for the vehicle, the premise of ensuring the smoothness of each road is to use each road in the city as a complete road traffic system to complete the road transport task. The specific implementation mode of the present invention is as follows:

[0028] refer to figure 1, in the vehicle-road coordination-based ur...

Abstract

The invention discloses a city vehicle navigation system based on vehicle-road synergy and solves the problem that the traveling dynamic states of other vehicles on a road section are not considered when navigation is provided for a vehicle. The city vehicle navigation system comprises a roadside system, a vehicular system, an intelligent mobile terminal and a server, wherein the intelligent mobile terminal is connected with a vehicular display device through a USB data line or Bluetooth; the roadside system comprises a roadside bearing device, a roadside wireless unit and a roadside information processing device; the roadside wireless unit comprises a wireless hot spot; the roadside information processing device is a PC104 embedded computer; the PC 104 embedded computer is connected with the wireless hot spot through a USB interface 2 and a data line, and the roadside system is wirelessly connected with the wireless unit of the vehicle system through the wireless hot spot; the roadside system is wirelessly connected with the data transceiving unit of the server through the remote communication module of the roadside wireless unit, and the wireless data transmission equipment of the data transceiving unit of the server is connected with the intelligent mobile terminal through a wireless network.

Description

technical field [0001] The invention relates to a navigation device in the fields of urban traffic management and vehicle navigation communication, more precisely, the invention relates to an urban vehicle navigation system based on vehicle-road coordination. Background technique [0002] Vehicle-road coordination technology is an intelligent transportation technology based on vehicle-to-vehicle communication and vehicle-road communication technology. Vehicles, roadside systems and traffic management centers can exchange information on vehicles and road conditions in real time. In recent years, with the popularity of automobiles and the construction of urban roads, urban road traffic has become more and more complicated, and traffic jams have become more and more common. Therefore, how to provide drivers with accurate navigation functions based on the built urban roads, and how to use the built urban roads to ensure the smoothest traffic of each road in the city is the main...
