So, through the accuse screen display different car machine functions in first side accuse screen 105 and the cooperation of second side accuse screen 106 in the multi-media to the user can use more car machine functions through the side accuse screen on the steering wheel directly, and provides more convenient operation mode for the user through the mode that provides two side accuse screens on the steering wheel, so, has promoted user experience.

For example, when a music playing interface is displayed on the multimedia central control screen, the first and second control screens 105 and 106 may display function interfaces corresponding to music functions, so that a user may directly perform operations such as volume up and down, playing a previous song, playing a next song, etc. on the first and second control screens 105 and 106, thereby implementing the corresponding music functions. In this way, the user directly operates on the first control screen 105 and the second control screen 106, and does not need to operate on the multimedia center control screen, so that convenience is improved, and user experience is improved.

Alternatively, the first control screen 105 may display a corresponding function of the vehicle, and the second control screen 106 may display a function adjustment interface corresponding to the target vehicle function.

In this case, the first side control screen 105 cooperates with the multimedia side control screen to display the corresponding functions of the vehicle, and then the second side control screen 106 may display a function adjustment interface corresponding to a certain function of the vehicle. Therefore, linkage control among the multimedia side control screen, the first side control screen and the second side control screen is realized, the technological sense of the cabin is improved, the problem that a user searches a plurality of keys in a target vehicle is avoided, and therefore user experience is improved.

For example, fig. 3 is a display interface of a first and a second control screen. Referring to fig. 3, fig. 3 includes a first control screen 105, a second control screen 106, and a multimedia center control screen 301. A plurality of scene controls 302 are displayed on the multimedia center control screen 301, and the plurality of scene controls 302 include an entertainment scene control 302, a driving scene control 302, and a default scene control 302.

When the user clicks the entertainment mode 302 on the multimedia center control screen 301, the function icons 303 of a plurality of functions corresponding to the entertainment mode 302 may be displayed on the first control screen 105.

So that the user can adjust various parameters of the music, such as adjusting volume, switching the previous song, the next song, etc., on the function adjusting interface displayed on the second side control screen 106.

Optionally, a plurality of spokes 102 and brackets 104 of the steering wheel are each provided with a screen mounting groove.

The screen mounting groove is used for mounting the square control screen. The screen mounting slot of a first spoke 102 of the plurality of spokes 102 is for mounting a first steering screen 105 and the screen mounting slot of a second spoke 102 of the plurality of spokes 102 is for mounting a second steering screen 106.

Alternatively, the shape of the screen mounting groove may be set according to the shapes of the first and second square screens 105 and 106. For example, the shapes of the first and second side control screens 105 and 106 are circular, and then the shape of the screen mounting groove may be set to be circular. For another example, the first and second pilot screens 105 and 106 may be rectangular in shape, and the screen mounting groove may be rectangular in shape.

Under the condition, the shape of the screen mounting groove is set according to the shapes of the first square control screen and the second square control screen, so that the steering wheel is more attractive, and the user experience is improved.

Optionally, a connection line may be disposed in the screen mounting slot, where the connection line in the screen mounting slot of the first spoke 102 is used to connect the first steering screen 105, so that the first steering screen 105 is connected to a CAN (Controller Area Network ) bus of the target vehicle, so that a communication connection between the first steering screen 105 and each controller (including a multimedia central control host) of the target vehicle may be achieved. The connection lines in the screen mounting slots of the second spoke 102 or the bracket 104 are used to connect the second side control screen 106, so that the second side control screen 106 is connected to the CAN bus of the target vehicle, and thus communication connection between the second side control screen 106 and each controller of the target vehicle CAN be realized.

Of course, the screen mounting groove may not be provided with a connecting line, and the first and second party control screens 105 and 106 may also access the CAN network through a wireless communication manner, so as to implement communication connection with each controller (including the multimedia central control host) in the target vehicle, which is not limited in the embodiment of the present utility model.

Alternatively, the first and second pilot screens 105 and 106 may be installed in the screen installation groove in two possible ways as follows.

In a first possible manner, the first steering screen 105 may be fixedly mounted in the screen mounting slot of the first spoke 102 and the second steering screen 106 may be fixedly mounted in the screen mounting slot of the second spoke 102 or the bracket 104.

In this way, the first and second pilot screens 105 and 106 can be fixed to the steering wheel body. When the user wants to use the car function, the first and second control screens 105 and 106 can provide the user with needs at any time, so that convenience is provided for the user.

In a second possible manner, the first and second pilot screens 105 and 106 may be detachable touch screens, in which case the first pilot screen 105 may be detachably mounted in the screen mounting groove of the first spoke 102 and the second pilot screen 106 may be detachably mounted in the screen mounting groove of the second spoke 102 or the bracket 104.

In the case where the user wants to use the first and second side control screens 105 and 106, the user may install the first side control screen 105 in the screen mounting groove of the first spoke 102 and install the second side control screen 106 in the screen mounting groove of the second spoke 102 or the bracket 104. In the case where the user does not want to use the first and second screens 105 and 106, the user can take out the first and second screens 105 and 106 from the corresponding screen mounting slots.

In this way, the first and second control screens 105 and 106 are more flexibly installed and used by the user. And after the user takes the first and second control screens 105 and 106 out of the corresponding screen mounting grooves, the user can avoid the false touch operation of the first and second control screens 105 and 106 when driving the vehicle, thereby ensuring the driving safety.

Alternatively, the first square control screen 105 may include a first screen body and a first MCU (Micro Controller Unit, micro control unit), and the second square control screen 106 may include a second screen body and a second MCU.

The first screen body is electrically connected with the first MCU, and the first MCU is used for controlling the first screen body to display the vehicle-to-machine function of the target vehicle. The second screen body is electrically connected with the second MCU, and the second MCU is used for controlling the second screen body to display the vehicle-to-machine function of the target vehicle.

In addition, the first MCU and the second MCU are respectively in communication connection with a CAN bus of the target vehicle to access a CAN network of the target vehicle, so that CAN communication with each controller (comprising a multimedia central control host) in the target vehicle is realized. That is, the first MCU and the second MCU receive various communication messages transmitted from respective controllers (including the multimedia center control host) of the target vehicle through CAN communication, and the first MCU and the second MCU transmit various communication messages to respective controllers (including the multimedia center control host) of the target vehicle through CAN communication.

Alternatively, the first screen body and the second screen body may be LCD (Liquid Crystal Display ) touch screens, which include a plurality of LED (Light-Emitting Diode) backlights, and the first MCU and the second MCU control the first screen body and the second screen body to emit Light through black Light PWM lines, respectively, and control and adjust the brightness of the LED backlights.

Optionally, the first screen body may further include a first pressure ram, and the first control screen 105 further includes a first pressure sensor; the second screen body may further include a second pressure ram, and the second pilot screen 106 may further include a second pressure sensor.

The first pressure sensor is electrically connected with the first MCU, and the second pressure sensor is electrically connected with the second MCU. The first pressure sensor is used for detecting the touch pressure value on the first control screen 105, and the second pressure sensor is used for detecting the touch pressure value on the second control screen 106.

When the first control screen 105 is pressed, the first screen body drives the first pressure ejector rod to move so as to contact the first pressure sensor, and the touch pressure value when the first control screen is pressed is detected through the first pressure sensor. When the second control screen 106 is pressed, the second screen body drives the second pressure ejector rod to move so as to contact the second pressure sensor, and the touch pressure value of the second control screen when pressed is detected through the second pressure sensor.

For example, fig. 4 is a schematic structural diagram of the first steering screen 105, referring to fig. 4, fig. 4 includes a first screen body 401, a first MCU402, a first pressure ejector 403, and a first pressure sensor 404.

When the user presses the first control screen 105, that is, presses the first screen body 401, the first screen body 401 is deformed when being pressed downward, and the first screen body 401 drives the first pressure ejector rod 403 to move along with the deformation of the first screen body 401. The first pressure ram 403 contacts the first pressure sensor 404 during movement, and the first pressure sensor 404 senses the pressure of the first pressure ram 403, thereby detecting a touch pressure value on the first touch screen 105.

It should be noted that, the structure of the first control panel 105 provided in fig. 4 may be used to detect the touch pressure value on the first control panel 105. It should be understood that the structure of the second control screen 106 is similar to that of the first control screen 105 in fig. 4, and the process of detecting the touch pressure value on the second control screen 106 is similar to that of detecting the touch pressure value on the first control screen 105, which will not be described in detail in the embodiment of the present utility model.

Optionally, the first screen body further comprises a first thermistor, and the second screen body further comprises a second thermistor.

The first thermistor is electrically connected with the first MCU, and the second thermistor is electrically connected with the second MCU. The first thermistor is used for detecting the screen temperature of the first square control screen 105, and the second thermistor is used for detecting the screen temperature of the second square control screen 106.

The first thermistor and the second thermistor are both sensor resistances, which can change with a change in temperature. In the embodiment of the utility model, the first thermistor may rise with the rise of the temperature of the first screen body, and the second thermistor may rise with the rise of the temperature of the second screen body.

Alternatively, a first thermistor may be connected in series with one fuse to connect with the first MCU and a second thermistor may be connected in series with the other fuse to connect with the second MCU.

In this case, since both the first thermistor and the second thermistor can rise along with the rise of temperature, the temperature of the first thermistor rises in the case that the screen temperature of the first control screen 105 is high, and then when the fuse point is reached, the fuse can be automatically fused to play a role of overheat protection, so that it can be ensured that each element is not damaged. And under the condition that the screen temperature of the second side control screen 106 is higher, the temperature of the second thermistor can rise, and then when the fuse point is reached, the fuse can be automatically fused to play a role of overheat protection, so that the elements can be prevented from being damaged.

Thus, by providing the first thermistor and the second thermistor, the temperatures of the first control panel 105 and the second control panel 106 can be detected, and the overheat protection effect is achieved on each element in the circuit.

Alternatively, the first square control screen 105 may further include a first touch unit and a first display unit, and the second square control screen 106 may further include a second touch unit and a second display unit.

The first touch unit is electrically connected with the first MCU, the first display unit is electrically connected with the first MCU, and the first touch unit and the first display unit are also respectively connected with the first screen body. The first touch unit is used for detecting a touch or press operation to the first control screen 105, and the first display unit is used for displaying functions of the vehicle machine through the first screen body.

The second touch unit is electrically connected with the second MCU, the second display unit is electrically connected with the second MCU, and the second touch unit and the second display unit are also respectively connected with the second screen body. The second touch unit is used for detecting touch or pressing operation on the second control screen 106, and the second display unit is used for displaying functions of the vehicle machine through the second screen body.

For example, fig. 5 is a schematic structural diagram of the first control screen 105, referring to fig. 5, fig. 5 includes a first screen body 401, a first touch unit 501, a first display unit 502, and a first MCU402.

In the case where one target scene is selected on the multimedia center control screen, the first center control screen 105 may display a plurality of car functions corresponding to the target scene.

Specifically, the first display unit 502 may control the first screen body 401 to display a plurality of vehicle functions corresponding to the target scene when receiving the vehicle function display instruction sent by the first MCU402. So that the user may then select the desired car function to be used on the first party control screen 105.

Alternatively, the first screen body may be a capacitive touch screen, in which case, the user's finger, the top end of the screen, and the surface of the screen may form a coupling capacitor, and when the first screen body is touched/pressed, that is, when the user's finger approaches the first screen body, the value of the coupling capacitor changes.

When the user selects a car function from the first control screen 105, that is, when the first control screen 105 is touched/pressed by the user's finger, the first touch unit 501 may recognize a change in the coupling capacitance value in the first screen body, so that it may be determined whether the first control screen 105 is touched/pressed according to the change in the coupling capacitance value.

Specifically, the first touch unit 501 may determine that the first touch screen 105 is touched/pressed in a case where the variation amount of the coupling capacitance value is greater than or equal to a preset variation threshold value, and the first touch unit 501 may determine that the first touch screen 105 is not touched/pressed in a case where the variation amount of the coupling capacitance value is less than the preset variation threshold value.

The preset change threshold may be preset, and the preset change threshold may be set larger.

In this case, in a case where the variation amount of the coupling capacitance value is greater than or equal to the preset variation threshold value, which means that the variation amount of the coupling capacitance value is large, which means that the user's finger may be pressing the screen, the first touch unit 501 may determine that the first control screen 105 is touched/pressed. In the case where the amount of change of the coupling capacitance value is smaller than the preset change threshold value, it is indicated that the amount of change of the capacitance value is not large, the user's finger is likely to be close to or just touching the first control screen 105, and is likely to be erroneously touching the first control screen 105, and in this case, the first touch unit 501 may determine that the first control screen 105 is not touched/pressed.
