Unmanned automobile automatic lane changing device and method

Abstract

The invention discloses an unmanned automobile automatic lane changing device and method. The unmanned automobile automatic lane changing device comprises an image collector, an image processor, a central processor module and a control execution system; the image collector is used for collecting a road marking line on a road surface, and the image processor is connected with image collector data and is used for receiving acquisition data of the image collector and recognizing image information of the image collector and distinguishing a function of the marking line; and the central processor module is connected with image processor data and used for performing comprehensive analysis and processing on a signal transmitted by the image processor according to a preset program and then sendingout a decision instruction, and is used for transmitting the decision instruction to the control execution system to control a vehicle to change lanes or not. According to the unmanned automobile automatic lane changing device and method, a road line is actively recognized without relying on a driver to complete an automatic lane change, various road conditions are flexibly dealt with, and the practicality is high.

Description

Technical field: [0001] The invention relates to an automatic lane changing device and method for an unmanned vehicle, and relates to the technical field of unmanned driving. Background technique: [0002] With the popularity of cars around the world, a large number of cars will inevitably require a large number of drivers. In order to avoid the waste of human resources, driverless cars are developing rapidly. At present, driverless cars mainly have two automatic lane changing methods: one is the driver Give the car an instruction to change lanes, and then the car will complete the lane change. This method still relies on the driver's judgment and instructions, and cannot realize true driverless driving. The other is that the car drives according to the established driving route and relies on the navigation system. Lane changing on the road, due to the complex natural conditions and the high real-time requirements of the system, the real-time recognition of traffic lines is ...

[0002] With the popularity of cars around the world, a large number of cars will inevitably require a large number of drivers. In order to avoid the waste of human resources, driverless cars are developing rapidly. At present, driverless cars mainly have two automatic lane changing methods: one is the driver Give the car an instruction to change lanes, and then the car will complete the lane change. This method still relies on the driver's judgment and instructions, and cannot realize true driverless driving. The other is that the car drives according to the established driving route and relies on the navigation system. Lane changing on the road, due to the complex situation under natural conditions, and the high real-time requirements of the system, the real-time recognition of traffic lines is not very effective in auxiliary navigation, and there are still many unsolvable problems
