Abstract

The invention relates to the field of vehicle control, in particular to a vehicle steering system. Comprising a steering wheel assembly, a vehicle body fixing part, a torque transmission mechanism, a rotation information acquisition device and a road feeling simulation driving device. The rotation information acquisition device is connected with the torque transmission mechanism, the road feeling simulation driving device is in driving connection with the torque transmission mechanism, and the rotation information acquisition device and the road feeling simulation driving device are respectively in communication connection with the controller; the torque transmission mechanism is connected with the vehicle body fixing part and the steering wheel assembly, and the road feeling simulation driving device is arranged to respond to the driving control instruction, operate based on the driving operation parameters and drive the torque transmission mechanism to rotate so as to output road feeling simulation torque to the steering wheel assembly through the torque transmission mechanism; according to the vehicle steering system, by arranging the torque transmission mechanism, the rotation information collecting device and the road feeling simulation driving device, the controller and the vehicle steering system can achieve the road feeling simulation function, and the using hand feeling of a driver is improved.

Description

technical field [0001] The present application relates to the field of vehicle control, in particular to a vehicle steering system. Background technique [0002] With the continuous development of automotive electronic control technology, intelligent automatic driving technology has gradually attracted the attention of the market. Steering by wire technology is one of the important technologies for vehicles to realize intelligent driving. The difference between the steer-by-wire system and the existing electronic power steering system is that the connection relationship between the steering device in the cockpit and the steering gear in the engine compartment has changed from a mechanical connection to an electronic connection, and the current status signal sent by the processor Realize precise steering control of the vehicle. [0003] However, the steer-by-wire device in the prior art has many parts and the layout is chaotic. The sliding of the steering wheel relative to t...
