Embodiment

[0048] Viewed from the front of the steering wheel 1 of the inventive device, if the driver turns the steering wheel 1 counterclockwise from the zero position at this time, the force-sensing controller 18 receives the signals of the rotation angle and the torque sensor 5 to determine the direction of the theoretical steering wheel torque. It is clockwise, and the direction of the damping torque is also clockwise; the force sense controller 18 transmits the size and direction of the returning torque to the motor controller 19, and the motor controller 19 receives the driving angle and torque detected by the torque sensor 5. The angle at which the driver turns the steering wheel 1 is used to determine the angle that the torsion spring 7 needs to compensate. If the torsion spring 7 is not enough to provide a large enough return torque under the action of the driver turning the steering wheel 1 counterclockwise, the motor 10 should pass through the motor worm 8 Drive the torsion sp...

Abstract

The invention discloses a magnetorheological fluid rotational spring force sense feedback apparatus and an application method thereof. The magnetorheological fluid rotational spring force sense feedback apparatus comprises a force sense simulation system, a force sense control system, an aligning torque generation system, a damping torque generation system and a power supply system. The aligning torque and the damping torque in the magnetorheological fluid rotational spring force sense feedback apparatus are separately controlled, so that the irregularity and delay characteristics of the control of the traditional torque motor can be eliminated; and moreover, an ordinary DC motor can be used, so that the cost of the apparatus can be decreased.

Description

technical field [0001] The invention belongs to the technical field of automobile electronic control and intelligence, and relates to a magneto-rheological fluid rotary torsion spring force-sensing 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 ...
