Eccentric steering
How it works: Eccentric wheels are a pair of wheels on either side of the vehicle whose position can be adjusted or tilted. By adjusting the position of the eccentric, it can produce different speed difference when turning, so as to realize the turning of the vehicle.
Features: The use of speed difference to achieve turning, the need for precise control and adjustment.
Axle steering
Principle: The axle of some rail flat cars can be rotated within a certain Angle range, so that the vehicle can change the Angle of the axle according to the need to achieve turning operation.
Application scenario: Suitable for large Angle turns or special trajectories.
Intelligent turning technology
With the development of science and technology, the rail flat car also uses intelligent turning technology, which mainly involves navigation and positioning, path planning, control technology and sensor technology.
Navigation and positioning: The use of magnetic navigation, laser navigation, inertial navigation and other technologies to determine the position and direction of the vehicle during the driving process.
Path planning: Through A* search algorithm, Dijkstra algorithm and other path planning algorithms, combined with the actual vehicle operating environment, to determine the optimal turning path.
Control technology: transform the result of path planning into actual driving instructions to control the turning process of the track flat car. Common control techniques include PID control, fuzzy control and so on.
Sensor technology: real-time monitoring of the status of the track flat car inside and outside, to provide data support for intelligent turning. Commonly used sensors include liDAR, cameras, gyroscopes and so on.
