Embodiment Construction

[0032] Such as figure 1 Shown, a kind of navigation device based on city road restriction rule, it comprises following unit:

[0033] The model building unit 10 is used to collect traffic restriction information in cities, and establish a unified model of city traffic restriction rules according to the city traffic restriction information. The unified model of urban traffic restriction rules includes traffic restriction help configuration files, traffic restriction rule configuration files, and traffic restriction road configuration files.

[0034] Optionally, the model building unit 10 includes:

[0035] Acquiring and dividing each urban road restriction rule; optionally, each urban road restriction rule is divided into odd and even number restriction, tail number restriction, restriction before and after the tail number, restriction on specified week, and restriction on specified week cycle.

[0036] Among them, odd and even numbers are restricted: on odd-numbered days, onl...

Abstract

A navigation device based on urban road restriction rules comprises a model establishment unit, a restriction city judgment unit, a regional restriction judgment unit, a restriction road section judgment unit, an intraday restricted number judgment unit and an extensible road management unit, wherein the model establishment unit is used for establishing an urban restriction rule unified model, the restriction urban judgment unit is used for judging whether a current city belongs to a restriction city or not, the regional restriction judgment unit is used for judging whether a current road section belongs to road restriction or region restriction or not, the restriction road section judgment unit is used for judging whether the road section belongs to the restricted period of time or not, the intraday restricted number judgment unit is used for judging whether a tail number of a vehicle belongs to the restricted number in the same day or not, and the extensible road management unit is used for bringing a current road section into a passable road collection of the route planning. The invention further provides a navigation method based on the urban road restriction rules.

Description

technical field [0001] The invention relates to the technical field of combination of urban road restriction rules and vehicle navigation devices, in particular to a navigation device and method based on urban road restriction rules. Background technique [0002] At present, with the continuous development of automotive electronics, car navigation has gradually become the standard configuration of cars. Accurate traffic information prompts and accurate navigation paths are the safety guarantee for drivers and passengers. At the same time, they can alleviate traffic congestion and prevent traffic accidents to a certain extent. occur. However, all kinds of navigation software in China have not yet applied the traffic restriction rules of Chinese urban roads, and their imperfect traffic information prompts and even wrong navigation routes will undoubtedly bring hidden dangers to the safe driving of drivers and passengers. If the city traffic restriction rules are applied to th...
