The invention relates to a magnetic navigation unmanned vehicle system with an automatic U-turn function. The magnetic navigation unmanned vehicle system with the automatic U-turn function comprises amagnetic navigation unmanned vehicle with an automatic driving function, a roadbed magnetic nail and a U-turn control method. The magnetic navigation unmanned vehicle with the automatic driving function mainly utilizes a magnetic ruler, the roadbed magnetic nail and a global map to achieve own high-precision positioning and achieve the functions of automatic navigation and automatic driving. Theroadbed magnetic nail utilizes the polarity information of the magnetic nail to achieve the marking of specific points, and these marking points are detected by the magnetic ruler to correct the poseinformation of the vehicle in operation. The proposed U-turn control method increases U-turn magnetic nail routes and U-turn specific marking points in the magnetic navigation unmanned vehicle system.The U-turn magnetic nail routes are used for a basic navigation, and the specific marking points are used for marking different stages of a U-turn operation and correcting an vehicle pose error whichmay exist in a U-turn process to ensure that the U-turn process is successfully completed. The magnetic navigation unmanned vehicle system with the U-turn function improves the flexibility of the operation of the magnetic navigation system, reduces the requirement of the system for a site and has great practical value.
Description
technical field [0001] The invention relates to a magnetic navigation unmanned vehicle system with an automatic U-turn function, in particular to an unmanned vehicle with an automatic U-turn function and a roadbed magnetic nail laying scheme based on a magnetic sensor and a magnetic navigation automatic driving algorithm. Background technique [0002] The main operation scenario of the existing magnetic navigation unmanned vehicles is a closed one-way circular road. In practical applications, due to site and road constraints or application requirements, magnetic navigation unmanned vehicles are required to have an automatic U-turn function. Different from the traditional one-way magnetic navigation unmanned vehicle, the magnetic navigation unmanned vehicle with automatic U-turn function needs to have functions such as automatic reversing, reversing dead reckoning, reversing automatic positioning and navigation, etc., so in vehicle positioning, navigation The three levels of...
