Steering gear of unmanned vehicle and control method thereof

Abstract

The invention discloses a steering gear of an unmanned vehicle and a control method thereof, wherein the steering gear is characterized by comprising a motor, a worm gear and a worm, an electromagnetic clutch and an encoder, wherein the motor is a steering drive mechanism; the worm gear and the worm are meshed with each other, and the worm is directly coupled with the output shaft of the motor; the electromagnetic clutch is fixedly coupled with the drive end of the electromagnetic clutch; and the encoder is fixedly coupled with a steering column of a steering wheel by the driven end of the electromagnetic clutch and is connected onto the output shaft of the rear end of the motor. The invention can realize the automatic steering control of the unmanned vehicle, can be freely switched between two modes of unmanned driving and manual driving the switching of which are not interfered with each other, and has compact structure, low cost, higher transmission efficiency, higher intelligent degree of vehicle automatic steering; and both the structure and the appearance of the original vehicle are not damaged, and the steering gear is easy to be assembled and dismantled and is applicable to other occasions with high automatic rotation requirements.

Description

technical field [0001] The present invention relates to vehicle steering devices. More specifically, it is a steering device and control method for an unmanned vehicle. Background technique [0002] Unmanned vehicles are one of the best platforms for validating theories, methods and techniques of machine perception and cognition, especially in unstructured and dynamically changing environments. Unmanned vehicles not only have broad application prospects in dangerous and harsh environments such as military, expedition and rescue, but also various automotive sensors, environmental perception systems, driving safety warnings and assisted driving intelligent decision-making involved in unmanned vehicles. Key technologies are of great significance for improving the intelligence and driving safety of manned vehicles. Therefore, major developed countries in the world regard unmanned vehicles as an important platform to demonstrate the level of artificial intelligence technology a...

Problems solved by technology

However, the structure of the two-stage gear transmission is complex, takes up a lot of space in the car, increases the transmission error of the movement, and increases the difficulty of installation. It is difficult to ensure the parallelism of the three axes of the motor shaft, the gear shaft and the central steering rocker arm. , this technical solution needs to weld the flange on the central steering rocker arm of the vehicle, which not only destroys the original structure of the vehicle, but also makes it difficult to assemble and disassemble the device
