Magnetic navigation unmanned vehicle based on road curvature map and road curvature map establishment method

Abstract

The invention provides a magnetic navigation unmanned vehicle based on a road curvature map and a road curvature map establishment method. The magnetic navigation unmanned vehicle based on the road curvature map comprises a vehicle body, a magnetic nail detection sensor, a dead reckoning sensor, a steering wheel angle sensor, a power driving system, a steering driving system, a control computer in which the curvature map is stored and an expected traveling track on which magnetic nails are laid, wherein the vehicle body serves as a carrier; the magnetic nail detection sensor and the dead reckoning sensor are used for establishing the road curvature map; the magnetic nail detection sensor is used for detecting the magnetic nails and calculating the deviation of the magnetic nails relative to the magnetic nail detection sensor; the dead reckoning sensor is used for tracking the detected magnetic nails, and a tracking result is used for calculation of information of the curvature map; on the condition of automatic driving of the vehicle, the control computer achieves prospective control in combination with positioning information of the vehicle and the information of the curvature map. The magnetic navigation unmanned vehicle based on the road curvature map greatly improves control performance and guarantees driving safety; the establishing process of the curvature map is automated, and the road curvature map is easy to realize.

Description

technical field [0001] The invention relates to an unmanned vehicle, in particular to a magnetic navigation unmanned vehicle based on a road curvature map and a method for establishing the road curvature map. Background technique [0002] From the day when the car was born, the problem of car and traffic safety has always been an important issue that people are committed to solving. Especially in a modern society, with the increasing number of cars, various car-related urban problems have emerged, such as traffic congestion, frequent traffic accidents, and vehicle exhaust pollution. Among the factors that lead to these problems, the human factor plays a large role. So people think of using technology to solve these problems by realizing the unmanned driving of cars. [0003] Among many unmanned vehicle solutions, magnetic navigation technology has become the closest unmanned vehicle technology to practical application due to its obvious advantages in reliability and wide a...
