specific Embodiment approach 1

[0018] Specific implementation mode one: refer to figure 1 This implementation mode is specifically described. A mapping corresponding mode steering control method described in this implementation mode includes the following steps:

[0019] Step 1. The controller establishes a real-time dynamic coordinate system, the positive direction of the x-axis of the dynamic coordinate system always points to the forward direction of the car body, and establishes a mapping relationship table according to the change angles of the two real-time dynamic coordinate systems at two adjacent moments, and the The mapping relationship table includes the change angle of two real-time dynamic coordinate systems at two adjacent moments and the number of pulses corresponding to the angle,

[0020] Step 2. The controller receives the digital signal sent by the remote controller, and parses the digital signal into a pulse signal containing the number of pulses. According to the mapping relationship tab...

Abstract

The invention discloses a mapping corresponding mode steering control system and method, and relates to the field of unmanned vehicle steering control. The invention aims to solve the problems of lowreaction speed and low rotating efficiency of the existing turning control technology. The method comprises the following steps: 1, a controller establishes a real-time dynamic coordinate system, thepositive direction of the x axis of the dynamic coordinate system always points to the advancing direction of a vehicle body, and a mapping relation table is established according to the change anglesof the two real-time dynamic coordinate systems at two adjacent moments, wherein the mapping relation table comprises change angles of two real-time dynamic coordinate systems at two adjacent momentsand the number of pulses corresponding to the angles; and 2, the controller receives a digital signal sent by a remote controller, analyzes the digital signal into a pulse signal containing the number of pulses, obtains the change angles according to the mapping relation table and the pulse signal, a steering motor changes the angle along with the change, and steering control of the motor is achieved. The system is used for controlling steering of the unmanned vehicle.

Description

technical field [0001] The invention relates to an unmanned vehicle control steering system and method, and belongs to the field of unmanned vehicle steering control. Background technique [0002] The existing turning control technology on unmanned vehicles adopts a gradual contrast method to realize turning. For example, when turning left 10 degrees, the steering motor will gradually rotate to turn the steering to 10 degrees. If you turn right ten degrees at this time, the motor will execute the next instruction after completing the last rotation instruction, so that the reaction speed is reduced and the rotation efficiency is low. Contents of the invention [0003] The invention aims to solve the problems of low response speed and low turning efficiency in the existing turning control technology. A steering system and method for controlling steering in a corresponding mapping mode are provided. [0004] A steering control method in a mapping corresponding manner, the m...
