Embodiment

[0044] Viewed from the front of the steering wheel 1 of the inventive device, the motor 9 rotates at a constant speed clockwise, and the ring gear and the small sleeve 8 fixed to it also rotates at a constant speed clockwise, but under the action of the reversing system, the sun gear and the small sleeve 8 fixed to it are also rotated at a constant speed clockwise. The large sleeve 6 rotates counterclockwise at a constant speed. Since the driving torque generated by the magneto-rheological fluid 19 has nothing to do with the speed difference, the difference in forward and reverse speeds has no effect on the system; at this time, the driver turns the steering wheel 1 counterclockwise from the zero position, and the force After the sense controller 27 obtains the size of the theoretical force sense, the theoretical current of the excitation coil is obtained through the magneto-rheological fluid controller 28. At the same time, the force sense controller 27 obtains that the directi...

Abstract

The invention discloses a planet-gear magnetorheological fluid dual-drum force feedback device and an application method thereof. The planet-gear magnetorheological fluid dual-drum force feedback device comprises a force simulation system, a force control system, a force generation system, a reversing system, and a power supply system. A dual-drum system is used herein and matched with a planet-gear reversing system such that no parameter change is involved in the control process; a sleeve-type reversing device is used herein so that space is saved, friction disc structure in other reversing structures is omitted, the quantity of parts is decreased, and the structural size is reduced; the reversing structure and the transmission structure are separate, such that the structures have clear functions.

Description

technical field [0001] The invention belongs to the field of automobile electronic control and intelligence, and relates to a planetary gear-type magneto-rheological fluid double-drum force-feedback device and a use method thereof. Background technique [0002] Traditional vehicle road tests have disadvantages such as high cost, long time, limited site conditions, and accidents in extreme conditions. It is the current mainstream trend to replace traditional vehicle road tests with vehicle driving simulation systems. A mature driving simulation system can truly reflect the vehicle's motion state, road conditions, surrounding environment, and various body and force sensations, which greatly reduces the capital cost, time cost and labor cost of the vehicle road test. Among them, accurate steering wheel force feedback is essential, which to a large extent determines whether the driver can make corresponding operations according to a given route or driving intention, and is cruci...
