Description

Navigation voice broadcasting method and device, electronic equipment and storage medium Technical Field The present application relates to the field of navigation technologies, and in particular, to a navigation voice broadcasting method and apparatus, an electronic device, and a storage medium. Background With the popularization of car navigation systems and mobile intelligent terminals, navigation voice broadcasting has become an important means for assisting driving. Existing navigation systems typically provide two basic options, detailed and succinct, that the driver can manually set before navigation begins. However, the voice broadcasting mode in the prior art has a problem of insufficient flexibility. On the one hand, drivers have a priori knowledge and memory of the surrounding road network environment when driving in a common urban area where they are traveling frequently. At this time, if the navigation system still adopts the detailed broadcasting mode, a large amount of non-core information such as road names, distances, landmarks and the like can be frequently broadcast, and redundant voice information can form hearing interference, so that the attention of a driver to an actual traffic environment is dispersed, and the driving comfort is affected. On the other hand, when a driver drives into a very common urban area, because the driver is unfamiliar with the environment of a strange road network, if the system is in a concise broadcasting mode currently, only the core steering action and the distance information are broadcasted, and the error of judgment of the driver at a complex intersection or a continuous steering point can be caused due to insufficient information quantity, so that a key maneuvering steering point is missed, and the path is deviated. Existing navigation systems typically require the driver to manually switch between the two modes. The manual switching operation is not only tedious, but also the driver can disperse energy when carrying out touch operation under high-speed driving or complex traffic conditions, and potential safety hazards exist. In addition, when the existing system is switched in mode or plays the prompt tone, the occupation detection of the navigation voice channel is lacking, the prompt tone or the system voice is easy to collide with the ongoing navigation guidance broadcasting in audio frequency, so that the road condition and the steering information with high priority are covered or interrupted, and the effective transmission of key information is affected. Therefore, the existing navigation voice broadcasting technology still needs to be improved in the aspects of information output accuracy, mode adjustment intellectualization and man-machine interaction safety. Disclosure of Invention The invention aims to provide a navigation voice broadcasting method and device, electronic equipment and a storage medium, at least solving the technical problems that the information output density cannot be adaptively matched with the environment familiarity degree and road condition complexity of a driver due to the stationarity of the conventional navigation voice broadcasting mode setting, and the problems that the hearing interference of the driver is large, key information is easy to lose and the potential safety hazard of the interactive operation of the driving is large caused by the method and the device. The invention provides the following scheme: the first aspect of the present invention provides a navigation voice broadcasting method, comprising the steps of: S1, acquiring a navigation destination request, analyzing the navigation destination request to obtain navigation destination position coordinate data, and determining common city information according to the navigation destination position coordinate data by using an address information inquiry module; The process of determining the common city information comprises the steps of receiving a common address confirmation signal generated by a cloud map service system according to historical navigation frequency statistics, calling a data retrieval interface of an address information storage module, performing space matching on navigation destination position coordinate data and geofence data in a local administrative division database, and outputting a city name code hit by matching as the common city information; S2, monitoring vehicle running state data in real time, wherein the vehicle running state data comprise an administrative city code where a vehicle is currently located, a current road grade identification value, a current effective voice broadcasting mode state and a presence state identification of a follow-up action of a front maneuvering point; S3, performing intelligent guidance judgment based on the common city information and the vehicle running state data to generate a detailed broadcasting mode recommendation instruction or a concise broadcasting mode recommendation instruction
