Abstract

The invention discloses an unmanned vehicle steering system and a control method thereof. The system comprises an execution motor, a steering machine, a motor coder, a non-contact type zero position detection mechanism, a non-contact type left limiting detection mechanism, a non-contact type right limiting detection mechanism, a front wheel absolute corner mechanism and a front wheel corner double closed loop control system. The execution motor is a steering driving mechanism, and the input end of the execution motor is connected with the output end of the steering machine. The motor coder is connected with an output shaft at the back end of the execution motor. The unmanned vehicle steering system is favorable for improving steering control accuracy of unmanned vehicles, adopts a selector switch to switch the control process of manual driving/ automatic driving, facilitates program debugging and ensures vehicle and personnel body safety under the emergency condition.

Description

technical field [0001] The invention belongs to vehicle steering technology, in particular to an unmanned vehicle steering system and a control method thereof. Background technique [0002] Unmanned vehicles are one of the future development directions of automobiles. It is expected that unmanned vehicles will become a safe means of transportation in people's lives in the future.
