Description

[0002] At present, autonomous driving, as a key technology and research direction of intelligent vehicles, has achieved certain research results. For autonomous vehicles, achieving automatic steering is an important condition for their normal driving. This is because the steering device determines important characteristics of the vehicle during driving, such as steering, flexibility, maneuverability, and stability.
[0003] Current navigation devices are generally arranged below the steering wheel. For example, in the related art, an invention patent with publication number CN108820032B discloses a steering device and control method for automatic driving of a vehicle. A gear ring assembly is used to connect the steering wheel to drive steering. By fixing the fixed claw on the inner gear ring and the steering wheel, the inner gear ring and the steering wheel can rotate synchronously. When the driving motor drives the driving gear to rotate, the driving gear drives the inner gear ring to rotate, thereby realizing automatic steering of the steering wheel.
[0004] However, this structure has great limitations. When it is necessary to switch to manual operation of the steering wheel, the fixing claw needs to release the clamping of the steering wheel. When it is necessary to switch from manual operation of the steering wheel to automatic operation of the steering wheel, the fixing claw and the steering wheel need to be fixed again. The operation is cumbersome and the switching between manual and automatic is not smooth enough. Utility Model Content
[0005] The purpose of the utility model is to provide an adjustable steering wheel system with a navigation function. When automatic navigation is required, the navigation motor can drive the steering wheel to rotate synchronously.
