Problems solved by technology

The use of motors as the actuators for road feel simulation has the following disadvantages: First, the use of motors as the actuators in the road feel simulation system belongs to active force feedback. When the control fails, the road feel simulation motors may drag the steering wheel Doing undesired sports, which can bring safety hazards and even cause accidents
Second, a requirement for car maneuverability is: w

Abstract

The invention provides a wire control steering automobile road sensing simulation executing device, which comprises a support mechanism, a magnetorheological damping device, a pair of torsional springs and a torsional spring following element, wherein the magnetorheological damping device is arranged on the support mechanism, damping device shafts of the magnetorheological damping device are connected with a steering wheel shaft of a steering wheel in an automobile, the pair of torsional springs are respectively arranged on the damping device shafts arranged at both sides of the torsional spring following element, the pair of torsional springs are in coaxial installation and have opposite torsion directions, one end of each torsion spring is fixed on the support mechanism, the other end of the torsion spring is connected with the torsional spring following element, and the torsional spring following element and the damping device shafts are in a circumferential position limiting state. When the wire control steering automobile road sensing simulation executing device is adopted, the structure is simple, the energy consumption is low, in addition, the safety is high, and an active return function is realized.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a steering-by-wire vehicle road feeling simulation execution device for a road feeling simulation system of a steer-by-wire vehicle. Background technique [0002] In a traditional car, the driver manipulates the car through the steering wheel, brake pedal, accelerator pedal, shift mechanism, etc., and these control mechanisms are generally connected with the final actuator through mechanical, hydraulic and other mechanisms. The difference is that in a car using wire control technology, the operating mechanism and its corresponding actuator are not directly mechanically connected, but are electrically connected: the driver manipulates the steering wheel (that is, the steering wheel of the car), the brake pedal, the accelerator, etc. The instructions generated by the pedals are first converted into electrical signals, and then transmitted to the electronic control unit via the cable; the ...
