Embodiment 1

[0046] For example, the vehicle command system received an instruction from No. 8 Zhongshan Road to No. 7 Yan'an Road at 5:06:23 pm on March 4, 2017.

[0047] Then the vehicle control system will do the following:

[0048] (1) According to the geographical database, the name of the building at No. 7 Yan'an Road is Huanghe Building, and the longitude and latitude coordinates are (8°E, 9°N). The name of the building at No. 8 Zhongshan Road is Zhongshan Building, and the longitude and latitude coordinates are (East Longitude 10°, 11° north latitude) to get the geographic location information of the departure and destination;

[0049] (2) From the geographic database, it is easy to obtain 7 different main paths from Zhongshan Building (10°E, 11°N) to Huanghe Building (8°E, 9°N), specifically path 1, path 2, path 3, and path 4, path 5; path 6, path 7;

[0050] (3) Let’s take Route 1 as an example to illustrate how to determine the road sections of the route: Route 1 consists of 3 r...

Abstract

The method provided by the invention is based on the normal distribution model of the congestion of each road section. Traffic data in a previous short time period are excavated and used. A statistical method is used to estimate the transit time of each road section, and then the time to drive from a departure point to a destination on an acquired path is acquired. A vehicle can achieve a certaindegree of automatic driving. According to the invention, the acquired data are less, so that data collection, communication and processing are fast; and the method has the advantages of simple and efficient data processing, fast result feedback, instantaneous processing and extremely low cost, and is easily popularized in a vehicle-mounted control system.

Description

technical field [0001] The invention relates to the technical field of control strategies considering path information, in particular to a method for determining a path and a speed for automatic driving of a vehicle. Background technique [0002] At present, people's requirements for travel are getting higher and higher, and they hope to reach their destination as soon as possible. There are many traffic jams in the central city, and the road conditions are becoming more and more complicated. [0003] For the path selection of the vehicle control system, the existing technologies are basically static processing or simple real-time selection of various navigations. The results are often too different from the actual ones, the data processing is extremely rough, and the accuracy rate is very low. Excavating past traffic data, it is impossible to reach the destination in the shortest time. My application number 2017111930629 proposes a solution, and the present invention cont...
