An accurate route generation method suitable for unmanned vehicles

Abstract

The invention relates to the field of automobile automatic control, and concretely relates to a method for generating route accurately used for pilotless automobile. The method is realized by including the step of determining the route, and also including the following steps: step 1, distinguishing the first route; step 2, detecting the signal of a positioning device; step 3, collecting the data of the visual features and recording the data of the driver information; step 4, forming a coordinate library of the visual features; and step 5, forming a driving scheme. The invention provides the method for generating route accurately used for pilotless automobile, and the method can automatically determine whether the road is the first route or not, can save the information of features, and can still complete automated driving when the navigation map has low accuracy or the environment is absence of GPS signal.

Description

technical field [0001] The invention relates to the field of automatic control of automobiles, in particular to a method for accurately generating a travel route suitable for driverless automobiles. Background technique [0002] As a means of transportation for people, automobiles have been widely popularized in recent years with the improvement of material living standards. In car driving, the driver's subjective factors are the root cause of many traffic accidents. In order to improve traffic safety and transportation efficiency, the research of autonomous driving and unmanned intelligent vehicles has been valued by many countries and has become an important research topic. content. A driverless car is also called a self-driving car or a wheeled mobile robot. It perceives the surrounding environment through on-board sensors without human input instructions, and relies on the computer control system in the car as the basis for the interactive information obtained. The mai...

Problems solved by technology

[0003] As mentioned above, the realization of unmanned vehicles includes at least three parts, namely a large number of sensors, positioning devices (such as GPS) and intelligent driving modules, such as the automatic navigation vehicle disclosed in the Chinese patent document with the publication number 100999202A, but currently Unmanned vehicles, especially the problems affecting the navigation technology of unmanned vehicles, are concentrated in two aspects, one is the accuracy of GPS navigation, and the other is the intelligence of map-based tracking technology

Specifically, because the car may enter an area with weak or no GPS signal during driving, automatic driving cannot be realized, or the signal collected by the sensor is weakened or even lost during driving, or, due to the GPS map update problem The data of the actual road and the electronic map do not match, and these situations will affect the accuracy of unmanned driving
