In fig. 1, an on-vehicle touch display screen 101 is disposed on a steering wheel 100, and the on-vehicle touch display screen 101 may include a plurality of key display areas, where different key display areas are used to display virtual keys with different functions. Since the in-vehicle touch display screen 101 is provided on the steering wheel 100, the in-vehicle touch display screen 101 may also be referred to as a square control screen.
For example, as shown in fig. 1, the in-vehicle touch display screen 101 may include a first touch screen 1011 and a second touch screen 1012, and the first touch screen 1011 and the second touch screen 1012 may be disposed in bilateral symmetry on the steering wheel 100. However, in a specific implementation, the first touch screen 1011 and the second touch screen 1012 may be arranged symmetrically up and down, and the orientation arrangement of the first touch screen 1011 and the second touch screen 1012 is not specifically limited in this embodiment. In addition, it should be noted that, in this embodiment, only two touch screens including the first touch screen 1011 and the second touch screen 1012 are taken as examples of the vehicle-mounted touch display screen 101, and in a specific implementation, the number of touch screens included in the vehicle-mounted touch display screen 101 is not taken as examples according to actual needs, for example, the vehicle-mounted touch display screen 101 may include multiple touch screens or one touch screen distributed in different areas on the steering wheel 100.

The following describes a method for displaying a virtual key in this embodiment, where the method for displaying a virtual key in this embodiment may be applied to a vehicle, and in particular, may be applied to a controller in the vehicle, where the controller may be a controller for controlling a vehicle-mounted touch display screen, and by using the controller, starting, closing, and displaying of the vehicle-mounted touch display screen may be controlled. The vehicle-mounted touch display screen can be provided with a key interface, the key interface can comprise a plurality of virtual keys, and different virtual keys can be used for controlling different functions.
Fig. 2 is a schematic flowchart of a method for displaying virtual keys according to an embodiment of the present application.
Step 201: it is determined whether a target function on the vehicle is on. If so, go to step 202, otherwise go to step 203. Wherein the target function can be controlled by a target virtual key on the key interface.
Step 202: and controlling the target virtual key to be displayed in a first display mode, wherein the first display mode is used for representing that the target virtual key is currently in an operable state.
Step 203: and controlling the target virtual key to be displayed in a second display mode, wherein the second display mode is used for representing that the target virtual key is currently in an inoperable state.
In the embodiment shown in fig. 2, in the case that the target function on the vehicle is turned on and off, the target virtual key for controlling the target function is displayed in two different display modes, so that the user can determine whether the target virtual key is currently operable or not based on the different display modes of the target virtual key, so that the user can clearly distinguish whether the target function can be controlled through the target virtual key or not at present, and the user can conveniently and effectively control the target function. And moreover, the control of the related functions of the vehicle can be realized through the software layer by the virtual keys on the vehicle-mounted touch display screen, the physical keys are replaced by the virtual keys on the vehicle-mounted touch display screen, the key requirements of a plurality of functions are realized, and the cost of the whole vehicle is reduced. Meanwhile, the virtual keys are positioned on the vehicle-mounted touch control display screen arranged on the steering wheel, so that a driver can directly perform related control operation on the steering wheel in the driving process without twisting a head to operate on the central control screen, the distraction of the driver is reduced, and the driving safety is improved to a certain extent.
The following describes a specific implementation of each step in the embodiment shown in fig. 2:
in step 201, the target function may be any one of the virtual keys displayed on the on-vehicle touch display screen that can be controlled.
By way of example, it may be determined whether the target function is on by: and after the controller of the vehicle-mounted touch display screen receives the first signal and the second signal, determining that a target function on the vehicle is started. The first signal is a target function starting signal, and the second signal is a signal representing that the target function starting signal is valid, namely whether the target function starting signal is available or not. And when the controller of the vehicle-mounted touch control display screen does not receive the first signal and the second signal, determining that a target function on the vehicle is not started.
In a specific implementation, after the intelligent driving controller or the multimedia host detects that the target function is started, the first signal and the second signal CAN be uploaded to a controller area network (Controller Area Network, CAN), and the controller of the vehicle-mounted touch display screen CAN receive the first signal and the second signal from the CAN network. In this embodiment, after the first signal and the second signal are received, it is determined that the target function on the vehicle is turned on, which is favorable for avoiding inaccurate determination results of whether the target function is turned on or not due to distortion of the target function turning on signal.
For example, if the influence of signal distortion is not considered, the controller of the vehicle-mounted touch display screen may also determine that the target function on the vehicle is turned on after receiving the first signal.
For example, when the target function includes a cruise function, the target virtual keys include a virtual key for adjusting a cruise speed and a virtual key for adjusting a cruise distance. Further, the virtual keys for adjusting the cruising speed may include a virtual key for increasing the cruising speed and a virtual key for decreasing the cruising speed. The virtual keys for adjusting the cruising distance include a virtual key for increasing the cruising distance and a virtual key for decreasing the cruising distance.
For example, referring to fig. 3, fig. 3 is a schematic diagram of a key interface displayed on a touch display screen of a vehicle. The 5 virtual keys in fig. 3 may be: a virtual key 3 for realizing a cruise distance level decrease function, i.e., for decreasing a cruise distance, a virtual key 4 for realizing a cruise distance level increase function, i.e., for increasing a cruise distance, a virtual key 1 for realizing a cruise speed increase function, and a virtual key 2 for realizing a cruise speed decrease function. In addition, the key interface can also comprise a virtual key 5 for realizing the self-defining function according to the actual requirement.
By way of example, it may be determined whether the cruise function is on by: and after the controller of the vehicle-mounted touch display screen receives the first signal and the second signal, determining that the cruising function on the vehicle is started. The first signal is a cruise start signal, which can be expressed as: hwp_mottypereqmode=0x1: ON. The second signal may be a signal indicating that the cruise on signal is active, i.e. whether the cruise on signal is available, may be expressed as: hwp_superavail=0x1:available.
In a specific implementation, after the intelligent driving controller detects that the cruise function is started, the first signal and the second signal CAN be uploaded to the CAN network, and the controller of the vehicle-mounted touch display screen CAN receive the first signal and the second signal from the CAN network. In this embodiment, after the first signal and the second signal are received, it is determined that the cruise function on the vehicle is turned on, which is favorable for avoiding inaccurate determination results of whether the cruise function is turned on or not due to distortion of the cruise on signal.
For example, when the target function includes a multimedia function, the target virtual key includes a virtual key for adjusting a volume and a virtual key for adjusting a play progress. Further, the virtual keys for adjusting the volume may include a virtual key for increasing the volume and a virtual key for decreasing the volume. The virtual keys for adjusting the progress of playback include a virtual key for switching to a previous song/previous set and a virtual key for switching to a next song/next set. The multimedia functions may include an audio play function, a video play function, and the like, among others.
For example, referring to fig. 4, it is assumed that fig. 4 is a schematic diagram of a key interface displayed on an on-vehicle touch display screen corresponding to a multimedia function. The 5 virtual keys in fig. 4 may be: the virtual key is positioned above the key interface and used for increasing the volume, the virtual key is positioned below the key interface and used for reducing the volume, the virtual key is positioned at the left side of the key interface and used for switching to the last song/last set, and the virtual key is positioned at the right side of the key interface and used for switching to the next song/next set. In addition, the key interface can also comprise a virtual key positioned in the middle of the key interface for realizing the pause/play function according to the actual requirement.
By way of example, it may be determined whether the multimedia function is on by: and after the controller of the vehicle-mounted touch display screen receives the first signal and the second signal, determining that the multimedia function on the vehicle is started. The first signal is a multimedia function starting signal, and the second signal may be a signal indicating that the multimedia function starting signal is valid. In a specific implementation, after the multimedia host detects that the multimedia function is started, the first signal and the second signal CAN be uploaded to the CAN network, and the controller of the vehicle-mounted touch display screen CAN receive the first signal and the second signal from the CAN network, so that the multimedia function is determined to be started.
For example, when the target function includes a rearview mirror adjustment function, the target virtual key includes a virtual key for adjusting a rearview mirror position. Further, the virtual key for adjusting the position of the rear view mirror may include: virtual keys for realizing the upward turning function, downward turning function, left turning function and right turning function of the rearview mirror respectively.
For example, referring to fig. 4, it is assumed that fig. 4 is a schematic diagram of a key interface displayed on a vehicle-mounted touch display screen corresponding to a rearview mirror adjusting function. The 5 virtual keys in fig. 4 may be: a virtual key which is positioned above the key interface and is used for realizing the upward turning function of the rearview mirror, a virtual key which is positioned below the key interface and is used for realizing the downward turning function of the rearview mirror, the left virtual key for realizing the left turning function of the rearview mirror is positioned on the left side of the key interface, the right virtual key for realizing the right turning function of the rearview mirror is positioned on the right side of the key interface, and the middle virtual key for realizing the exit adjusting function is positioned in the middle of the key interface.
For example, when the target function includes a head-up display adjustment function, the target virtual key includes a virtual key for adjusting a head-up display position and a virtual key for adjusting brightness. Further, the virtual keys for adjusting the head-up display position include virtual keys for implementing a down-shift function and an up-shift function of the interface. The virtual key for adjusting brightness includes: virtual keys for implementing the brightness increasing function and the brightness decreasing function of the interface.
For example, referring to fig. 4, it is assumed that fig. 4 is a schematic diagram of a key interface displayed on a vehicle-mounted touch display screen corresponding to a head-up display adjustment function. The 5 virtual keys in fig. 4 may be: the device comprises a virtual key, a virtual key and a virtual key, wherein the virtual key is positioned above a key interface and used for realizing the upward movement function of the interface, the virtual key is positioned below the key interface and used for realizing the downward movement function of the interface, the virtual key is positioned at the left side of the key interface and used for realizing the brightness reduction function of the interface, the virtual key is positioned at the right side of the key interface and used for realizing the brightness increase function of the interface, and the virtual key is positioned in the middle of the key interface and used for realizing the exit regulation function.
For example, when the target function includes a steering wheel adjustment function, the target virtual key includes a virtual key for adjusting a steering wheel column. Further, the virtual key for adjusting the steering column includes: virtual keys for realizing the pipe column tilting function and the pipe column tilting function, and virtual keys for realizing the pipe column retracting function and the pipe column extending function.
For example, referring to fig. 4, it is assumed that fig. 4 is a schematic diagram of a key interface displayed on a vehicle-mounted touch display screen corresponding to a steering wheel adjusting function. The 5 virtual keys in fig. 4 may be: the virtual key is positioned above the key interface, is positioned below the key interface, is used for realizing the pipe column tilting function, is positioned at the left side of the key interface, is used for realizing the pipe column retracting function, is positioned at the right side of the key interface, is used for realizing the pipe column extending function, and is positioned in the middle of the key interface, is used for realizing the virtual key of exiting the adjusting function.
For example, when the target function includes an air conditioning function, the target virtual key includes: the virtual key is used for adjusting the temperature of the air conditioner and the virtual key is used for adjusting the air quantity of the air conditioner.
For example, referring to fig. 4, it is assumed that fig. 4 is a schematic diagram of a key interface displayed on an on-vehicle touch display screen corresponding to an air conditioning function. The 5 virtual keys in fig. 4 may be: the air conditioner comprises a virtual key, a virtual key and a virtual key, wherein the virtual key is positioned above a key interface and used for increasing the air conditioner temperature, the virtual key is positioned below the key interface and used for reducing the air conditioner temperature, the virtual key is positioned at the left side of the key interface and used for reducing the air quantity, the virtual key is positioned at the right side of the key interface and used for increasing the air quantity of the air conditioner, and the virtual key is positioned in the middle of the key interface and can be used for exiting the air conditioner adjustment.
In this embodiment, the manner of determining whether the air conditioning function, the steering wheel adjusting function, the head-up display adjusting function, and the rearview mirror adjusting function on the vehicle are on is similar to the manner of determining whether the cruise function is on or determining whether the multimedia function is on, so that the description thereof will not be repeated.
In step 202, if the controller of the vehicle-mounted touch display screen determines that the target function is turned on, the target virtual key is controlled to be displayed in a first display mode, where the first display mode is used for representing that the target virtual key is currently in an operable state. When the target virtual key is currently in an operable state, if a gesture operation such as pressing, touching, sliding, etc. of the target virtual key is detected, the gesture operation may be responded. For example, the controller may initiate the detected gesture operation to the multimedia host or the intelligent driving controller, so that the multimedia host or the intelligent driving controller performs the functional operation corresponding to the gesture operation.
Whether the gesture operation is sent to the multimedia host or the intelligent driving controller depends on whether the target function to be realized by the target virtual key is controlled by the multimedia host or the intelligent driving controller. If the target function to be achieved by the target virtual key is performed by the multimedia host control, the gesture operation may be transmitted to the multimedia host. If the target function to be realized by the target virtual key is controlled by the intelligent driving controller to be executed, the gesture operation can be sent to the intelligent driving controller.
In step 203, the controller of the vehicle-mounted touch display screen determines that the target function is not turned on, that is, the target function is turned off, and controls the target virtual key to be displayed in a second display mode, where the second display mode is used for indicating that the target virtual key is currently in an inoperable state. When the target virtual key is currently in an inoperable state, if a gesture operation such as pressing, touching, sliding, etc. of the target virtual key is detected, the gesture operation may not be responded. For example, even if the controller detects a gesture operation, the gesture operation is not transmitted to the multimedia host. Alternatively, when the target virtual key is currently in an inoperable state, a gesture operation for the target virtual key may not be detected.
The first display mode and the second display mode are different display modes, so that a user can distinguish whether the target virtual key can be operated currently or whether the target virtual key is necessary to be operated or not through the different display modes. For example, if the target function is currently in an off state, operation of the target virtual key may not be necessary.
In an exemplary embodiment, the first display mode is to display the target virtual key in a first color, and the second display mode is to display the target virtual key in a second color, where the first color is different from the second color. The first color and the second color can be set according to the requirements of the user, so that the user can quickly distinguish whether the target virtual key is currently operable according to different key display colors.
For example, the background color of the vehicle-mounted touch display screen may be black, the first color may be white, and the second color may be gray, so that under the black background, the white target virtual key may be more easily distinguished as an operable virtual key, and the gray target virtual key is an inoperable virtual key.
For example, assuming that the target function is a cruise function, referring to fig. 5, fig. 5 is a schematic diagram of a key interface when the cruise function is turned on and off. As can be seen from fig. 5, the target virtual key for controlling the cruise function includes: virtual keys 1 to 4. Fig. 5 (a) is a schematic diagram of the key interface when the cruise function is on. Fig. 5 (b) is a schematic diagram of the key interface when the cruise function is turned off.
For example, it may be determined whether a target function on the vehicle is on under the condition that the entire vehicle is powered up. When the whole vehicle is not electrified, the CAN transceiver in the vehicle-mounted touch control display screen is kept in a sleep state, and the vehicle-mounted touch control display screen is in a closed state. For example, the controller (Microcontroller Unit, MCU) of the on-vehicle touch display receives the power-off signal system=0x0 on the CAN network: and when the vehicle-mounted touch display screen is off, the CAN transceiver in the vehicle-mounted touch display screen is controlled to keep sleeping, and the vehicle-mounted touch display screen is not started.
Taking the target function as an example of the cruise function, the following two cases that may occur will be described below: when the power-on and cruising functions of the whole vehicle are started, and the power mode of the vehicle is in an on gear, the vehicle-mounted touch display screen receives a power-on signal system on the CAN network, wherein the power-on signal system=0x1: when in on, the CAN transceiver in the vehicle-mounted touch control display screen uploads signals to the MCU, and the MCU controls the vehicle-mounted touch control display screen to be started. When the cruise function is on, the intelligent driving controller sends hwp_supraavail=0x1:available, hwp_mottypereqmode=0x1: and after the MCU receives the two signals from the CAN network, the MCU controls the vehicle-mounted touch display screen to set the display color of the virtual key for adjusting the cruising speed and cruising distance to be white, and normally transmits related signals for operating the vehicle-mounted touch display screen by a driver.
When the whole vehicle is electrified and the cruising function is turned off, and the power mode of the vehicle is changed from an off gear to an on gear, the MCU receives a power on signal system on the CAN network, wherein the power on signal system=0x1: when in on, the CAN transceiver in the vehicle-mounted touch control display screen uploads a power on signal to the MCU, and the MCU controls the vehicle-mounted touch control display screen to be started. When the cruise function is off, the intelligent drive controller sends hwp_supraavail=0x0:notavailable and hwp_mottypereqmode=0x0: and after the signals are received from the CAN network, the MCU controls the vehicle-mounted touch display screen to change the display color of the virtual key for adjusting the cruising speed and cruising distance from white to gray, and related signals for the driver to operate the vehicle-mounted touch display screen are not transmitted.
In an exemplary embodiment, the target virtual key is used to adjust the function parameter associated with the target function, and the implementation of step 202 may include: when the target function is started, determining whether an adjusting space exists for the function parameters of the target virtual key; and under the condition that the existence of the adjusting space is determined, the control target virtual key is displayed in a first display mode.
The function parameter associated with the target function may correspond to a preset adjustment interval, and the adjustment interval may correspond to an adjustment upper limit value and an adjustment lower limit value. When the current parameter value of the function parameter is larger than the adjustment lower limit value and smaller than the adjustment upper limit value, it can be determined that the target virtual key has an adjustment space for the function parameter. When the current parameter value of the function parameter is smaller than or equal to the adjustment lower limit value or larger than or equal to the adjustment upper limit value, it can be determined that the target virtual key does not have an adjustment space for the function parameter.
When the target function is started and an adjusting space exists for the function parameters through the target virtual key, the fact that the target virtual key is currently operable is indicated, the operation of the target virtual key is effective and meaningful, and the actual adjusting effect on the function parameters can be achieved. When the target function is started and the target virtual key has no adjusting space for the function parameters, the target virtual key is indicated to be operable at present, but the operation of the target virtual key is basically invalid and meaningless, and the actual adjusting effect on the function parameters is not achieved.
In this embodiment, when the target function is turned on and the function parameter still has an adjustment space, the target virtual key is controlled to be displayed in the first display mode, so that the user can clearly learn that the target function is turned on based on the display mode of the virtual key, and the function parameter still has an adjustment space, which is favorable for adjusting the function parameter more effectively, and avoiding ineffective adjustment of the function parameter.
In an exemplary embodiment, in the event that it is determined that there is no adjustment space, the control target virtual key is displayed in the second display manner. Namely, for the target virtual key without an adjusting space, the user can clearly know that the target virtual key cannot be adjusted currently through the second display mode.
For example, when the target function is a multimedia function, the function parameters associated with the multimedia function may include volume and play progress. The upper and lower adjustment limits corresponding to the volume are the upper and lower volume limits Ymax and Ymin. The adjustment upper limit value and the adjustment lower limit value corresponding to the play progress may be a play start position and a play end position. For example, the play start position may be the first in the play list, and the play end position may be the last in the play list. Assuming that the current play volume y=vmin, i.e., the play volume has been adjusted to the minimum value, it indicates that there is no adjustment space for the volume by the virtual key for decreasing the volume and there is an adjustment space for the volume by the virtual key for increasing the volume.
For example, when the target function is an air conditioning function, the function parameters associated with the air conditioning function may include an air conditioning temperature and an air conditioning air volume. The adjustment upper limit value and the adjustment lower limit value corresponding to the air conditioner temperature may be the temperature upper limit value Tmax and the temperature lower limit value Tmin. The adjusting upper limit value and the adjusting lower limit value corresponding to the air conditioner air volume can be an air volume upper limit value Smax and an air volume lower limit value Smin.
For example, when the target function is a cruise function, the cruise function-associated function parameters may include cruise speed and cruise distance. The adjustment upper limit value and the adjustment lower limit value corresponding to the cruising speed are the speed upper limit value Vmax and the speed lower limit value Vmin. The adjustment upper limit value and the adjustment lower limit value corresponding to the cruising distance are the distance upper limit value Dmax and the distance lower limit value Dmin. Assuming that the current cruising speed v=vmax, i.e. the cruising speed has been adjusted to a maximum value, it is indicated that there is no adjustment space for the cruising speed for the virtual key for increasing the cruising speed and there is an adjustment space for the cruising speed for the virtual key for decreasing the cruising speed.
Referring to fig. 5, assuming that the current cruising speed v=vmax, i.e., the cruising speed has been adjusted to the maximum value, it is indicated that the virtual key 1 for increasing the cruising speed has no adjustment space for the cruising speed and the virtual key 2 for decreasing the cruising speed has an adjustment space for the cruising speed. At this time, the virtual key 1 may be displayed in the second display mode, and the virtual key 2 may be displayed in the first display mode. Assuming that the current cruising distance D is greater than the distance lower limit value Dmin and less than the distance upper limit value Dmax, it is explained that there is an adjustment space for both the virtual keys 3 and 4 for decreasing and increasing the cruising distance, at which time the virtual keys 3 and 4 may be displayed in the first display manner.
In this embodiment, the virtual keys with the adjustment space and the virtual keys without the adjustment space are displayed in different display modes, so that the user can clearly perceive whether the function reaches the limit value or not, and clearly understand the adjustment state.
In an exemplary embodiment, the determining whether the adjustment space exists for the functional parameter of the target virtual key includes: receiving a current parameter value of a functional parameter sent by a multimedia host; and determining whether an adjusting space exists for the functional parameters of the target virtual key according to the comparison relation between the current parameter value and the preset limit value corresponding to the functional parameters. For example, if the current parameter value reaches the preset limit value corresponding to the functional parameter, it is indicated that the target virtual key does not have an adjustment space for the functional parameter, and if the current parameter value does not reach the preset limit value corresponding to the functional parameter, it is indicated that the target virtual key has an adjustment space for the functional parameter. The preset limit value may include the above-described adjustment upper limit value and adjustment lower limit value.
For example, when the target function is a multimedia function, the current parameter values of the function parameters transmitted by the multimedia host may include: current volume value. The multimedia host can send the current volume value to the controller of the vehicle-mounted touch display screen after detecting the volume change each time. Therefore, the controller can control the display mode of the target virtual key for adjusting the volume according to the comparison relation between the current volume value and the upper and lower volume values Ymax and Ymin.
If the current volume value has reached Ymax, the controller may control the virtual key for increasing the volume to be displayed in the second display mode and control the virtual key for decreasing the volume to be displayed in the first display mode. For example, the color of the virtual key for increasing the volume is adjusted from white to gray, and the color of the virtual key for decreasing the volume is white. At this time, even if a gesture operation of the user to the virtual key for increasing the volume is detected, no response is made any more. And if a gesture operation of the user on the virtual key for reducing the volume is detected, the gesture operation is normally responded.
If the current volume value has reached Ymin, the controller may control the virtual key for decreasing the volume to be displayed in the second display mode and control the virtual key for increasing the volume to be displayed in the first display mode. For example, the color of the virtual key for reducing the volume is adjusted from white to gray, and the color of the virtual key for increasing the volume is white. At this time, even if a gesture operation of the user to the virtual key for reducing the volume is detected, no response is made any more. And if a gesture operation of the user on the virtual key for increasing the volume is detected, the gesture operation is normally responded.
If the current volume value is between Ymin and Ymax, the controller may control the virtual keys for decreasing the volume and the virtual keys for increasing the volume to both be displayed in a first display manner, such as both being displayed as white. At this time, after the detected gesture operation of the user on the virtual key for reducing the volume and the virtual key for increasing the volume, the gesture operation is normally displayed.
In an exemplary embodiment, the determining whether the adjustment space exists for the functional parameter of the target virtual key includes: determining whether a target signal sent by the multimedia host is received, wherein the target signal is used for representing that the multimedia host detects that the functional parameters are regulated to preset limit values; when a target signal is received, determining that no adjustment space exists; when the target signal is not received, it is determined that there is an adjustment space. The preset limit value may include the above-described adjustment upper limit value and adjustment lower limit value. In this embodiment, the multimedia host may determine whether the current volume value reaches a preset limit value after detecting that the volume changes each time, and if it is determined that the current volume value reaches the preset limit value, may send a target signal to the controller of the vehicle-mounted touch display screen, and if it is determined that the current volume value does not reach the preset limit value, may not send a signal. Therefore, the controller of the vehicle-mounted touch control display screen can determine that the target virtual key does not have an adjusting space for the functional parameters after receiving the target signal. In this embodiment, the controller of the vehicle-mounted touch display screen may directly determine whether the adjustment space exists based on whether the target signal is received, and the judgment manner for the controller is simpler.
In this embodiment, under two conditions of opening and closing a target function on a vehicle, a target virtual key for controlling the target function is displayed in two different display modes, so that a user can determine whether the target virtual key is currently operable or not based on different display modes of the target virtual key, so that the user can clearly distinguish whether the target function can be controlled through the target virtual key at present, and the user can conveniently and effectively control the target function. Moreover, the virtual keys with the adjusting space and the virtual keys without the adjusting space are displayed in different display modes, so that a user can clearly perceive whether the functions reach the limit value or not and clearly know the adjusting state. And moreover, the control of the related functions of the vehicle can be realized through the software layer by the virtual keys on the vehicle-mounted touch display screen, the physical keys are replaced by the virtual keys on the vehicle-mounted touch display screen, the key requirements of a plurality of functions are realized, and the cost of the whole vehicle is reduced. Meanwhile, the virtual keys are positioned on the vehicle-mounted touch control display screen arranged on the steering wheel, so that a driver can directly perform related control operation on the steering wheel in the driving process without twisting a head to operate on the central control screen, the distraction of the driver is reduced, and the driving safety is improved to a certain extent.
