Embodiment 1

[0042] For example, the vehicle control system received an instruction from No. 8 Zhongshan Road to No. 7 Yan'an Road at 5:06:23 p.m. on March 4, 2017.

[0043] Then the vehicle control system will do the following:

[0044] (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;

[0045] (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;

[0046] (3) Let’s take Route 1 as an example to illustrate how to determine the road sections of the route: Route 1 consists of...

Abstract

The invention discloses a general control strategy for a dynamic path and a speed of a vehicle. The general control strategy is based on a general time model of each road section, mines and utilizes traffic data of a former short time period, estimates transit time of each road section by adopting the traditional method, and further obtains the driving time from a departure to a destination by adopting a selected path. The vehicle can achieve a certain degree of automatic driving. The data adopted by the method is not much, so the data acquisition, communication and processing are very fast, the data processing method is simple and efficient, the result feedback is extremely fast, the instantaneous processing can be realized, the cost is extremely low, and the general control strategy is easy to popularize in vehicle control systems.

Description

technical field [0001] The invention relates to the technical field of control strategies considering path information, in particular to a general control strategy for dynamic paths and speeds of vehicles. 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-mounted control and command 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 is very low. It is impossible to reach the destination in the shortest time due to the excavation of past traffic data. My application number is 2017111517373, which proposes a solution, and...
