Auxiliary driving system and method for rapid passing of vehicle in crossing

Abstract

The invention discloses an auxiliary driving system and method for rapid passing of a vehicle in a crossing. The system comprises an information collection module, a vehicle positioning module, a barrier identification module, a database module, a signal lamp information module, a vehicle auxiliary decision module and an automobile power system. According to technical features of road traffics and physical features of drivers, a method including guiding information through which each crossing can be passed rapidly and smoothly and a vehicle in front can be overtaken is provided for the driver in the driving process, the guiding information including whether to overtake, the concrete driving speed and the like, and thus, when the vehicle is driven according to the guiding speed and manner, the crossing can be passed without stop, and core technical support is provided for development of Internet of vehicles and automatic driving technologies.

Description

technical field [0001] The invention belongs to the technical field of vehicle assisted driving in traffic and transportation engineering, and in particular relates to a vehicle fast-passing assisted driving system and method at road intersections by using distance measuring sensors and precise positioning of vehicles. Background technique [0002] It is the expectation of drivers and traffic control departments to quickly pass through intersections controlled by signal lights without stopping to avoid delays at intersections, and to achieve energy conservation and environmental protection. Drivers can drive at the speed they want, and the development of automatic driving and Internet of Vehicles technology, especially the development of vehicle ad hoc network, has made it possible. The main obstacle to energy saving and smooth traffic becomes the coordination of vehicles and intersection lights. On the premise of ensuring safety, how to help drivers to drive as smoothly as ...

Problems solved by technology

[0009] 3. There are only two master thesis papers on the smooth passage of intersections

②Disadvantages

②Disadvantages

It only considers a single vehicle in the design of the speed algorithm, which does not conform to the actual road traffic, and does not take into account multiple vehicles and overtaking situations; information collection is limited to GPS, and there is no automatic identification between vehicles, vehicles and other road facilities. Consider; use the Kalman filter method to improve the positioning accuracy of the vehicle. In some cases, it is difficult to obtain the prior value of the filter, which is not conducive to improving the positioning accuracy; the single-chip microcomputer is used as the system platform, the capacity is too small, and the system implementation is limited
