Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right with reference to the accompanying drawings, unless otherwise specified. "inner and outer" refer to the inner and outer contours of the component itself.
Referring to fig. 1 to 3, in a first aspect, the present invention provides a control system for a steering wheel, where the system includes a torque detection element for detecting a torsional moment of the steering wheel 1 in a decoupled state, and a torque feedback mechanism capable of applying a drag torque to the steering wheel 1 according to the torsional moment detected by the torque detection element, so as to enhance an operation feel of the steering wheel 1.
Wherein the decoupled state of the steering wheel 1 refers to a state when the steering wheel 1 is decoupled from the wheels. At this time, when the user operates the steering wheel 1 to rotate, the wheels cannot be driven to turn, and the automobile is in a game mode. In the embodiment of the invention, the torque detection element such as the torque sensor is used for detecting the torsion torque of the steering wheel 1 in the decoupling state, and the reverse dragging torque is fed back to the steering wheel 1 through the torque feedback mechanism. In this way, when the user operates the steering wheel 1 to rotate, the user can feel certain resistance, and therefore the game experience of the user is improved.
The corresponding relation between the dragging torque and the detected torsion torque is established through tests and is stored in the controller 7 in advance, the controller 7 controls the size of the dragging torque output by the torque feedback mechanism according to the detected torsion torque, and the optimal game experience can be given to a user.
The torque feedback mechanism may be of various configurations. In a preferred embodiment, the torque feedback mechanism comprises: a driving member for providing a driving force; a transmission member for transmitting the driving force provided by the driving member to the steering wheel 1 to apply the drag torque; and the controller 7 is used for controlling the driving part to provide the driving force according to the torsional moment detected by the moment detection element.
Specifically, the driving component may be, for example, the motor 5, the controller 7 may be, for example, a single chip microcomputer or a programmable logic controller 7, and the controller 7 may control the input current of the motor 5 according to the detected magnitude of the torsional moment so as to change the driving force output by the motor 5.
The driving force is transmitted to the steering wheel 1 by a transmission member, which may be a conveyor belt, for example. For example, a first roller may be mounted on the output shaft of the motor 5, a second roller may be mounted on the output shaft 2 of the steering wheel 1, and the first roller and the second roller may be drivingly connected by a belt mounted thereon. The output shaft 2 of the steering wheel 1 is a rotating shaft connected to the steering wheel 1 to rotate synchronously. The output shaft 2 is generally coaxially fixed to the center of one side of the steering wheel 1.
In a preferred embodiment, to reduce the bulk of the torque feedback mechanism, to facilitate installation of the torque feedback mechanism. The transmission member includes a second gear 4 fixed coaxially with the output shaft of the motor 5, and a first gear 3 fixed coaxially with the output shaft 2 of the steering wheel 1, wherein the first gear 3 and the second gear 4 are engaged. The output shaft of the motor 5 is parallel to the output shaft 2 of the steering wheel 1, when the output shaft of the motor 5 rotates, the second gear 4 is driven to rotate synchronously, the second gear 4 drives the first gear 3 to rotate, and the first gear 3 drives the output shaft 2 of the steering wheel 1 to rotate synchronously, so that dragging torque is applied to the steering wheel 1.
More preferably, the diameter of the second gear 4 is smaller than the diameter of the first gear 3. Through the transmission of the transmission part with the structure, the effects of reducing the speed and increasing the torque can be achieved, namely, the transmission part reduces the rotating speed output and increases the torque output, so that the motor 5 with a small size can be selected to feed back a large torque to brake the steering wheel 1, and the occupied space and the size of a torque feedback mechanism can be reduced.
Further, in order to realize coupling or decoupling between the steering wheel 1 and the wheels, the system provided by the embodiment of the invention further comprises a decoupling device, wherein the decoupling device can decouple the steering wheel 1 and the wheels when receiving a decoupling instruction of a user, so that the automobile enters a game mode.
However, after the steering wheel 1 is decoupled, since the user operates the steering wheel 11 to steer while playing the game, the steering wheel 1 may no longer be located at the steering angle before decoupling after the game is ended. The deflection of the steering wheel 1 causes the deflection of the output shaft 2, and when the output shaft 2 and the steering end shaft 9 are not aligned any more, the wheels and the steering wheel 1 cannot be coupled again after the game, so that the normal use of the automobile is influenced.
In order to solve the above technical problem, in a preferred embodiment of the present invention, the system further includes an angle detection element for detecting a steering angle of the steering wheel 1 before and after the game, and the torque feedback mechanism is further capable of driving the steering wheel 1 to return to the right according to a deviation of a rotation angle of the steering wheel 1 before and after the game.
In particular, the angle detection element may be an angle sensor, which may be integrated with the torque sensor. That is, the torque moment of the steering wheel 1 and the steering angle of the steering wheel 1 can be detected by the moment angle sensor 6. Therefore, the whole volume of the control system is reduced, and the system is convenient to install.
The moment feedback mechanism can output dragging moment to the output shaft 2 of the steering wheel 1 when the automobile exits from the game mode, so that the steering wheel 1 is controlled to recover to a steering angle before decoupling, and the decoupling device can be smoothly coupled with the output shaft 2 and the steering end shaft 9.
The hardware structure of the torque feedback mechanism may be the same as the torque feedback mechanism described above. The difference is that the driving force output by the moment feedback mechanism is different, and the action is different. The torque fed back by the foregoing torque feedback mechanism is generally relatively small, which is merely used to enhance the operational experience of the user. The drag torque for driving the steering wheel 1 back is generally relatively large, and the purpose thereof is to drive the steering wheel 1 to turn after the game is finished.
In some cases, the wheel may be subjected to other external forces, such as high winds or scratches by the automobile vehicle, resulting in a smaller deflection of the wheel, which may result in the wheel no longer being at the pre-decoupling steering angle.
In order to avoid that the coupling device cannot couple the wheel and the steering wheel 1 smoothly due to the deflection of the wheel. In a preferred embodiment of the present invention, the system may further include an angle detecting element for detecting a deflection angle of the wheel, and the controller 7 may simultaneously receive detection data of the angle detecting element for detecting a steering angle of the steering wheel 1 and detection data of the angle detecting element for detecting a deflection angle of the wheel and combine the deflection angles to control the rotation of the steering wheel 1, thereby more precisely controlling the output shaft 2 and the steering end shaft 9 of the steering wheel 1 to be aligned with each other.
After the steering wheel 1 and the wheels are decoupled through the decoupling device, the rotation angle of the steering wheel 1 is not limited, and when the rotation angle of the steering wheel 1 exceeds the allowable amount of the clock spring, the wire harness of the clock spring may be broken. In order to protect the clock spring, the steering angle of the steering wheel can be detected through the angle detection element, and when the steering angle of the steering wheel exceeds an allowable range, a large dragging torque is applied to the output shaft of the steering wheel to prevent the steering wheel from rotating continuously.
A second aspect of the embodiments of the present invention provides a method for controlling a steering wheel 1, where the method includes:
detecting the torsion moment of the steering wheel 1 in a decoupling state;
and applying reverse drag torque to the steering wheel 1 according to the torsion torque to enhance the operation hand feeling of the steering wheel 1.
In order to detect a torsional moment of the steering wheel 1 in the decoupled state, the method further comprises:
the steering wheel 1 and the wheels are decoupled to put the car into play mode.
Further, in order to smoothly couple the steering wheel 1 and the wheels after the automobile game mode is finished, the method further includes:
detecting the steering angle of the steering wheel 1 before and after the game;
driving the steering wheel 1 to return to the right according to the rotation angle deviation of the steering wheel 1 before and after the game;
after the game mode is finished and the steering wheel 1 is turned back, the steering wheel 1 and the wheels are coupled.
The control method of the steering wheel 1 provided in the second aspect of the embodiment of the present invention corresponds to the control system of the steering wheel provided in the first aspect of the embodiment of the present invention, and the advantages of the control method and the further detailed description of the parameters of the control system of the first aspect of the embodiment of the present invention are not repeated here.
Referring to fig. 3, in addition, based on the control method of the steering wheel provided in the first aspect of the embodiment of the present invention, the third aspect of the embodiment of the present invention further provides an automobile, where the automobile includes the control system of the steering wheel according to the first aspect of the embodiment of the present invention.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention. Including each of the specific features, are combined in any suitable manner. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
