[0053] Furthermore, the above implementation scheme can reduce the size of the overall structure in the axial direction to meet the requirements of installation in the limited space between the instrument panel and the steering wheel, and realize the coexistence of the two driving modes of the vehicle steering system, namely, the electronic control and manual driving. When the vehicle needs to be remotely controlled or automatically driven, the power component 4 is powered on to receive the control signal from the remote control or the driving computer in real time, rotates according to the control, and drives the first transmission member 2, that is, the driving gear to rotate, and then drives the second transmission member 5, that is, the keyless driven gear to rotate.
