Detailed Description

The invention will be further described with reference to specific embodiments and drawings, the advantages and features of which will become more apparent as the description proceeds.

Referring to fig. 1 and 2, in a preferred embodiment, the steering wheel of the present invention includes a body 1, wherein the body 1 is coupled to an On-board diagnostics (hereinafter, OBDII) system On a vehicle computer 2 of a vehicle, and includes: a set of keys 11 (such as a left key 11a and a right key 11b shown in fig. 2) as an operating device, a display device 12 including a display screen 12a, a left rotation speed indicator 12b and a right rotation speed indicator 12c, a speaker 13 as an alarm device, a host 14, a bluetooth module 15 including a wireless transceiver device, and a power controller 16.

The host 14 includes an interface generating device 141 and a brightness control unit 142, the interface generating device 141 includes an MCU14a and a storage unit 14b, and the interface generating device 141 is coupled to the bluetooth module 15, the brightness control unit 142, the power controller 16, the operating device, the display device 12, and the speaker 13.

The power controller 16 is configured to obtain power provided by an external power source, and the power controller 16 includes a power protection and filter 16a and a transformer 16b, as shown in the figure, in this embodiment, the external power source is provided to the host 14 after being processed by the power protection and filter 16a, and the power provided to the MCU14a of the host 14 is further reduced by the transformer 16b after passing through the power protection and filter 16 a; in various embodiments of the present disclosure, the external power source may be provided by a power system of the vehicle itself, or other external power sources, or other power devices of the existing vehicle-mounted devices.

Functionally, the interface control unit obtains a plurality of driving information by connecting to an OBDII bluetooth unit connected to the OBDII through the bluetooth module 15, then divides the plurality of driving information into a plurality of display information which is desired to be displayed on the display device 12 and a plurality of hidden information which is not desired to be displayed on the display device 12 according to an operation instruction input by a user on the plurality of keys 11, adds the plurality of display information into a customized page transmitted to the display device 12, then replaces a set page displayed on the display device 12 from an initial page to the customized page, and displays the plurality of display information through the display screen 12a and the plurality of

speed indicator lamps

12b and 12 c; since the OBDII can be an existing device, the present steering wheel can be applied to different kinds of vehicles having the device.

The storage unit 14b can store the initial page and the custom page generated by the interface generating device, so that a user can select whether the content of the set page is the newly generated custom page or the existing custom page or the initial page after replacing the set page according to a requirement.

The display information may be an image message displayed by the display screen 12a, a light message displayed by the plurality of speed indicator lights 12b1, 2c through a change of light signal (controlled by the brightness control unit 142), or a sound message provided by the speaker 13.

The host 14 may further generate an alarm message for activating the speaker 13 according to a setting condition input by the user through the operating device and the driving message (including the display message), and the speaker 13 generates an alarm sound to warn the user after receiving the alarm message.

Therefore, the utility model discloses the steering wheel can produce device 141 according to user's demand through its interface that has, produce the required self-defined interface of user (the self-defined page) and show on the screen in the multiple driving information that the vehicle provided, convenience of customers can produce self-defined display interface according to self driving custom or information demand.

Referring to fig. 3, in the embodiment, the host 14 first determines whether the host 14 is in the power-on state, if so, the host 14 determines that the host is in the sleep state, and then determines whether to keep the sleep state continuously according to whether a power-on key (not shown) is pressed, or the MCU14a of the interface control unit is connected to the OBDII of the vehicle through the bluetooth module 15, and transmits a key stored in the storage unit 14b to the OBDII for authentication, so as to facilitate the subsequent step of obtaining the driving information of the vehicle through the OBDII.

Then, the interface control unit, in cooperation with the setting of a setting page, distinguishes the display information and the hidden information from the plurality of types of driving information obtained through the OBDII, obtains the plurality of display information, and displays the plurality of driving information classified as the display information on the display device 12 (including the display screen 12a and the left and right speed indicator lights 12 and 12 c).

Wherein, the setting page is preset and stored in the original page of the storage unit 14b before sale by the manufacturer of the host 14 as the initial user when the device of the present invention is used for the first time, and is changed to the self-defined page according to the setting of the operation instruction inputted by the user; the driving information that can be set on the setting page to be displayed or not can include: rotation speed indication, brightness, unit, F2 driving information setting, F3 driving information setting, and the setting condition as an alarm setting value.

The utility model discloses it does not have the injeciton how interface control unit obtains to be shown on display screen 12a the mode of driving information can be according to the settlement of setting for the page, will obtain earlier driving information divides into display information reaches after hiding the information, only pass through bluetooth module 15 obtains to be categorised as display information driving information also can be after obtaining all driving information again according to whether driving information does display information and decide whether to show on display screen 12 a.

When the driving information is displayed by the left and right speed indicator lights 12c under the control of the host 14, the left and right speed indicator lights 12c dynamically display the left and right

speed indicator lights

12b, 12c according to the driving information and the indicator light information generated by the host 14 according to the speed indication setting, for example, when the engine speed is increased, the brightness of the left speed indicator light 12b is controlled or the number of the light bulbs is increased or decreased.

Then, the host 14 will determine whether the value of the driving information exceeds the set alarm value set by the setting condition according to the setting condition and the driving information input by the user to determine whether to generate the alarm signal for activating the speaker 13 or to control the display device 12 to give an alarm to the user.

Finally, the host 14 will determine whether the user presses a power-off key (not shown) to enter the sleep state, or continue to display the driving information in accordance with the setting of the setting page.

When the user wants to change the setting page, the host 14 determines whether to let the user reset the content of the setting page (i.e. the condition for distinguishing the displayed information from the hidden information) according to whether the user presses a setting page key (belonging to the operating device) or not.

The driving information is not limited to the type of the driving information, and may be driving information obtained from the driving computer 2, or driving information obtained by another method, for example, an additional sensor externally connected to the user; in addition, in some embodiments, the driving information may be the driving information generated by the host 14 after calculating the information provided by the bicycle computer 2.
