Embodiment
[0043] Such as figure 1 As shown, the present embodiment is a personalized navigation method for route planning at night, which specifically includes the following steps:
[0044] Firstly, the preparatory work before data collection is carried out, specifically:
[0045] (0) An intelligent vehicle-mounted box that integrates the collection of light intensity data is installed on the OBD interface of different vehicles;
[0046] (1) Initialize the position illumination database and obtain the position illumination database.
[0047] Step (1) is specifically:
[0048] (1.1) Distribute light intensity data collection tasks to different vehicle users who install smart car boxes through crowdsourcing mode;
[0049] (1.2) The smart car box judges the light intensity. If the light intensity is lower than a certain critical value, collect data such as light intensity, location, and time.
[0050] (1.3) Upload data such as light intensity, location, and time to the cloud server, wh...

The invention discloses an individualized navigation method for planning a path at night. The individualized navigation method comprises the following steps of: S1, initializing a position light illumination database to obtain the position light illumination database; S2, rearing a starting point and a finishing point; judging current light illumination intensity; if the light illumination intensity is lower a certain critical value, starting a night map mode; uploading the starting point and the finishing point to a cloud server; S3, reading a position light illumination and night historicaltrack database, setting new weights for roads where light illumination exists and an automobile passes at night, and keeping original weights for other roads; S4, carrying out path planning accordingto the calculated new weights through an optimal path planning algorithm; S5, driving the automobile according to a pre-set path and collecting the light illumination intensity; S6, comparing with position light illumination of the database, if the light illumination does not exist or has errors, updating the database; meanwhile, uploading a night path route. The individualized navigation method for planning the path at night is realized through carrying out path planning on the road weights added with light sources and night driving records.
Description
technical field [0001] The invention belongs to the technical field of route planning, and in particular relates to a personalized navigation method for route planning at night. Background technique [0002] Path planning refers to the selection of appropriate paths based on different algorithms for the starting point and the ending point. At present, vehicle path planning focuses on the optimization of road planning algorithms, and path planning is realized by adding different parameters. [0003] However, the existing path planning technologies are generally applicable navigation methods. These navigation methods will not show shortcomings during the day, but at night, the shortcomings are very obvious. For example, it is impossible to plan a route with the most light sources. routes, or plan the most familiar routes for drivers at night. In terms of providing drivers with the safest personalized night-time route planning, there is no mature research and application. In...
