Abstract

The invention discloses a zero calibration unmanned steering engine and a control method. The device comprises an infrared sensor, a ball head bearing, a stepping motor, a push rod and a single-chip microcomputer system. The stepping motor drives the push rod; the wheels are stretched by the push rods to rotate; an infrared induction signal is adopted to determine the zero position of the wheel; the infrared sensor adopted by the invention has the characteristics of low cost, simple modification and good induction effect; a stepping motor is used as a steering driving motor; the steering control system has the characteristics of controllable steering angle, controllable steering speed and forward and reverse rotation control, adopts the push rod as a steering transmission mechanism, has the characteristics of simple connection and low cost, adopts the single chip microcomputer for signal receiving and output processing, is sensitive in response control, and is small in size, low in cost and convenient to popularize and use.

Description

technical field [0001] The invention belongs to the field of automatic control systems, in particular to a zero-calibration driverless steering machine and a control method. Background technique [0002] The electric power steering system (referred to as EPS) is used for driverless steering. The system drives the steering shaft through a DC motor, and then turns the steering linkage to turn the wheels, and then feeds back the current turning angle through the angle sensor, and uses an analog signal Or the CAN communication will send out the rotation angle parameter. The EPS rotation error is small, but its motor power is large, generally around 200W, its volume is large, and its price is high, so it is not easy to popularize. Therefore, a kind of volume is less, and the appearance of the novel driving steering system with low power and low cost is imminent. Contents of the invention [0003] The purpose of the present invention is to provide a zero calibration unmanned s...
