Automatic driving steering system and vehicle

Abstract

The invention provides an automatic driving steering system. A vehicle body sensor arranged around a vehicle body is used to detect a surrounding environment; a calculation processing module is used to receive a detection signal of the vehicle body sensor, and calculate and output a steering signal. The system is provided with at least two wheels, which are steering wheels, in the same row, the steering wheels are connected to the vehicle body through a fixed frame, the bottom of the fixed frame is fixedly connected with an inner ring of a slewing bearing, an outer ring of the slewing bearingis provided with external teeth and is fixed to a wheel bracket, the wheel bracket is rotatably connected with the wheels, and the wheels are driven to move forward or backward by a hub motor; a steering actuator receives a steering signal from a calculation processing module, and can mesh with the external teeth on the outer ring of the slewing ring to drive the outer ring of the slewing ring torotate. The steering is performed by the teeth meshed with each other, so that a mechanical transmission structure is omitted; the steering of the vehicle is realized by the slewing bearing, so that the rotation of a larger angle can be realized.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, and further relates to an automatic driving steering system and a vehicle. Background technique [0002] Self-driving car is a smart car that realizes unmanned driving through the processor computer system. The processor computer system can automatically judge the driving road conditions, control the speed and steering, and liberate the driver's hands. It is the trend of future car development. At present, there are Numerous companies are developing self-driving cars. [0003] The structure of the current self-driving car is basically the same as that of the traditional car. The engine drives the wheel movement through the gearbox, or the motor drives the wheel movement through a series of transmission structures. The steering shaft of the steering wheel rotates, and the steering shaft drives the wheels to turn through the traditional structure of a system. The steering drive de...

[0003] The structure of the current self-driving car is basically the same as that of the traditional car. The engine drives the wheel movement through the gearbox, or the motor drives the wheel movement through a series of transmission structures. The steering shaft of the steering wheel rotates, and the steering shaft drives the wheels to turn through the traditional structure of a system. The steering drive device receives the control commands issued by the computer system. The steering system is more complicated than the traditional car steering system, which is not conducive to reducing vehicle weight and high hardware costs. And it is not conducive to energy saving and consumption reduction
