Embodiment

[0046] The motor 9 rotates clockwise at a constant speed of 2 revolutions per second, and the first inner rotor 22 and the second inner rotor 19 also rotate at the same speed. After the magnitude of the theoretical steering wheel torque is obtained, the theoretical current of the excitation coil is obtained through the magneto-rheological fluid controller 29. At the same time, the force-sensing controller 26 obtains that the direction of the theoretical steering wheel torque should be clockwise, then the magneto-rheological fluid The controller 29 controls the current generator 30, selects to supply power to the second excitation coil 5 connected to the second rotor system, and the excitation coil of the second rotor system generates a magnetic field to the magnetorheological fluid 20 inside to change the magnetic field. When the viscosity of the rheological fluid 20 reaches an appropriate level, under the action of the second inner rotor 19 rotating clockwise, the second outer...

Abstract

The invention discloses a force sense feedback device made from magnetorheological fluid double rotors and a using method of the force sense feedback device. The force sense feedback device made fromthe magnetorheological fluid and the double rotors comprises a force sense simulation system, a force sense control system, a force sense generating system, a reversing system and a power supply system. According to the force sense feedback device made from the magnetorheological fluid the double rotors, a gear of a planetary wheel type reversing mechanism adopts an ordinary straight gear form, machining is easy, and the process cost is saved; in addition, the axial distance of a planetary wheel system is less, the axial distance of the device is advantageously decreased, and the mounting space of the device is reduced; and moreover, additional force attached to the axial direction cannot be generated in the torque transmitting process by a planetary wheel, the double sets of rotors cannotbear axial thrust, and the service life of the device is prolonged advantageously.

Description

technical field [0001] The invention belongs to the field of automobile electronic control and intelligence, and relates to a force-feedback device made of magnetorheological fluid double rotors and a method for using the same. 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 crucial t...
