Embodiment Construction
[0032] The specific implementation of the present invention will be described in detail below in conjunction with preferred embodiments.
[0033] see attached figure 1 , the present invention provides a relay navigation method for a smart car driving on urban roads, which divides urban roads into three types of typical road areas, different typical road areas adopt different navigation modes, and the main control program realizes the navigation mode between different navigation modes. The seamless handover between them, the on-board sensor confirms the navigation route. The smart car uses the cloud computing location service center to correct the positioning accuracy during driving, so that the positioning accuracy error does not exceed 1m.
[0034] The smart car implements and verifies the relay navigation strategy supported by cloud computing, and divides urban roads into three typical areas: road sections, intersection transition areas, and intersections. The specific defi...

The invention relates to a relay navigation method for an intelligent vehicle running in an urban road. The method is characterized in that an urban road is divided into three kinds of typical road areas, different navigation modes are adopted in the different typical road areas, the connection of the different navigation modes is achieved through a master control program, a vehicle-mounted sensor verifies a navigation line, and the intelligent vehicle achieves and verifies a relay navigation strategy supported by cloud computing in the driving process. The relay navigation method has the advantages that the relay navigation method is adopted in the intelligent vehicle, the different navigation modes are used in the different typical areas of the urban road, the seamless connection of the navigation modes is achieved, and the navigation problem of urban intelligent driving is effectively solved; the intelligent vehicle carries out locating precision correction in the driving process with the help of a cloud computing position service center, the total software and hardware resources of the intelligent vehicle are optimized, the loads of the intelligent vehicle are made to be balanced, and computing cost is lowered; the relay navigation mode reflects the environment self-adaption capacity of the intelligent vehicle, and provides important technical supports for the achievement of urban intelligent driving.
Description
technical field [0001] The invention belongs to intelligent driving, and in particular relates to a relay navigation method for an intelligent vehicle running on an urban road. Background technique [0002] Intelligent driving technology involves computer science, communication science, cognitive science, vehicle engineering, electrical and electronic engineering, control science and engineering, system science and technology, human-machine engineering science, artificial intelligence and many other sciences. Smart cars are a measure of a country's scientific research strength. And one of the important symbols of industrial level. The emergence of unmanned vehicles has fundamentally changed the vehicle driving mode in the traditional "human-vehicle-road" closed-loop system, and liberated drivers from long-term tedious, low-level, and long-lasting driving activities. Advanced sensors and information technology control vehicle driving, allowing routine, long-lasting, low-leve...
