The invention relates to a steer-by-wire column and a steer-by-wire control method, which comprises: a housing; a sleeve motor installed in the housing; an upper mandrel for connecting with the steering wheel, which is inserted in the In the sleeve motor, and the upper mandrel is connected with the sleeve motor through the first drive assembly; when the sleeve motor rotates, the sleeve motor can drive the sleeve motor through the first drive assembly The upper mandrel moves along the axial direction of the upper mandrel. The invention relates to a steer-by-wire column and a steer-by-wire control method with a simple structure, and after the collision and collapse, the sleeve motor can be controlled to reverse, so that the upper core shaft can move out of the casing and enter normal use. state, the collapse process of the steering-by-wire steering column is reversible, and the column does not need to be replaced after collision collapse occurs.
Description
technical field [0001] The invention relates to the technical field of automobile steering systems, in particular to a steer-by-wire steering column and a steering-by-wire control method. Background technique [0002] At present, the steering-by-wire system is a new generation of steering system developed after EPS (Electronic Power Steering System), which has better handling stability than EPS, and it no longer uses a mechanical connection between the steering wheel and the steering wheel. , completely get rid of the inherent limitations of the traditional steering system, while bringing convenience to the driver, it also improves the safety of the car. [0003] In related technologies, since the steering column cannot transmit torque and road feel through mechanical connections, it is generally necessary to install a feedback motor on the steering column to provide steering resistance and simulate road vibrations to provide a comfortable driving and control experience. If ...
