The second mode is as follows:
the method comprises the steps that a rotor position sensor of a power-assisted steering motor in a vehicle is used for obtaining the position of a rotor in real time and sending the position of the rotor to a screen controller, and the screen controller receives the position of the rotor and calculates the steering direction and the steering angle of a steering wheel 1 based on a preset calculation formula.

Therefore, the steering direction and the steering angle of the steering wheel are acquired, and the display content in the display area is adjusted in real time according to the steering direction and the steering angle, so that the display direction of the display content is kept unchanged, and the display content in the display area of the touch screen 2 is prevented from rotating along with the steering wheel 1.
S120: when the gesture operation aiming at the display area is monitored, the operation content corresponding to the gesture operation is executed based on the vehicle control function integrated in the display area.
In the embodiment of the invention, in order to improve the convenience of human-computer interaction of a driver, the inventor sets gesture operation on the display area, the gesture operation can replace the function of a button, and when the driver needs to operate the vehicle control function integrated in the display area, the command can be sent to the display area through the gesture operation.
When the screen controller monitors gesture operation aiming at the display area, operation content corresponding to the gesture operation is executed based on the vehicle control function integrated in the display area.
As can be seen from the above, the steering direction and the steering angle of the steering wheel can be obtained in real time, the display content in the display area can be adjusted in real time according to the steering direction and the steering angle, and the display direction of the display content is maintained unchanged; when the gesture operation aiming at the display area is monitored, the operation content corresponding to the gesture operation is executed based on the vehicle control function integrated in the display area. In the embodiment of the invention, the touch screen is arranged in the middle of the steering wheel, and the vehicle control function is integrated in the display area of the touch screen, so that the control of the vehicle control function through a software layer is realized, the use of physical function keys on the vehicle is reduced, the functions can be directly increased or decreased on the software layer when being increased or decreased, the human-computer interaction can be continuously optimized and upgraded, and when the vehicle control function comprises the control function of the in-vehicle display equipment, a driver can complete the control of the in-vehicle display equipment through gesture operation, the human-computer interaction convenience is improved, the distraction of the driver is reduced, and the driving safety is improved.
In addition, the embodiment of the invention does not need to change the mechanical structure of the steering wheel in a large scale, and is beneficial to realizing the scheme.
Fig. 4 is a schematic diagram of a display area according to an embodiment of the present invention, referring to fig. 4, the display area is divided into a central sub-area 5 and at least one peripheral sub-area 6, the at least one peripheral sub-area 6 includes a receiving sub-area, and as for which peripheral sub-area 6 is set as the receiving sub-area, a driver can set the receiving sub-area according to his driving habits.
The receiver area is integrated with a vehicle driving assistance control function and a control function of an in-vehicle base device.
Wherein the storage sub-area integrated vehicle-assisted driving control functions may include at least two of:
an ACC (Adaptive Cruise Control) function, a LKAS (Lane Keeping Assist System) function, an LDWS (Lane Departure Warning System) function, a TJA (Traffic Jam Assist System) function, or an AVP (Automated Valet Parking System) function;
the control functions of the sub-area integrated in-vehicle base unit may include at least two of:
an air conditioner gear adjusting function, a seat heating gear adjusting function or a seat ventilation gear adjusting function.
Of course, the vehicle driving assistance control function integrated in the storage sub-area and the control function of the in-vehicle basic device are not limited to the above-mentioned functions, and this is not limited in any way in the embodiment of the present invention, for example: the control functions of the in-vehicle base equipment integrated in the storage sub-area may further include an opening and closing function of a trunk, an adjusting function of an atmosphere lamp, an adjusting function of screen brightness, a call function, and/or an opening and closing function of multimedia, and the like, which may be integrated into the storage sub-area.
The sub-areas other than the receiving sub-area are integrated with control functions of different in-vehicle display devices, the number of the peripheral sub-areas 6 can be set according to actual needs of a driver, and exemplarily, the number of the peripheral sub-areas 6 can be 4, as shown in fig. 4, the central sub-area 5 is E, and the peripheral sub-areas 6 are A, B, C and D, respectively. The peripheral sub-area C can be set as the storage sub-area, the control function of the head-up display HUD display device is integrated in the peripheral sub-area A, the control function of the central control screen is integrated in the peripheral sub-area B, the control function of the vehicle auxiliary driving control function and the control function of the vehicle interior basic device are integrated in the peripheral sub-area C, namely the storage sub-area, the control function of the digital instrument screen is integrated in the peripheral sub-area D, and the central sub-area E corresponds to the touch screen of the steering wheel.
The number of the peripheral sub-regions other than the accommodation sub-region is related to the number of the in-vehicle display devices, and the driver can set the number of the peripheral sub-regions other than the accommodation sub-region by himself or herself according to the number of the in-vehicle display devices.
In the case that the display area is divided into the central sub-area 5 and the at least one peripheral sub-area 6, the step S120 may include:
when monitoring a first gesture operation of drawing from the receiving subarea to the central subarea 5, amplifying the central subarea 5 to a preset size, and reducing each peripheral subarea to a corresponding size;
displaying an auxiliary driving application corresponding to the control function of the in-vehicle basic equipment integrated in the receiving sub-area and a basic equipment control application corresponding to the control function of the in-vehicle basic equipment to the enlarged central sub-area, and executing operation content corresponding to second gesture operation when second gesture operation aiming at the displayed application is monitored;
alternatively, the first and second electrodes may be,
integrating a vehicle auxiliary driving control function integrated with the storage sub-area and a control function of the basic equipment in the vehicle into the enlarged central sub-area, and executing operation contents corresponding to a third gesture operation when the third gesture operation aiming at the enlarged central sub-area is monitored.
By default, i.e. in the initial state, the central sub-area 5 and the peripheral sub-areas 6 do not display anything in order to avoid false triggering. In order to use the function of integrating the receiving sub-regions, a driver needs to perform a gesture operation of scribing from the receiving sub-regions to the central sub-region 5, and when the screen controller monitors a first gesture operation of scribing from the receiving sub-regions to the central sub-region 5, it is known that the driver needs to use the function of integrating the receiving sub-regions, at this time, the central sub-region 5 is enlarged to a preset size, and each peripheral sub-region is reduced to a corresponding size, so that an effect of unfolding the receiving sub-regions is achieved as shown in fig. 5, where fig. 5 is another schematic view of a display region provided by an embodiment of the present invention. The driver can set the preset size.
After the central sub-area 5 is enlarged to a preset size, there are various ways of performing gesture operation, including but not limited to the following two ways:
the first mode is as follows:
and displaying the auxiliary driving application corresponding to the control function of the in-vehicle basic equipment integrated in the storage sub-area and the basic equipment control application corresponding to the control function of the in-vehicle basic equipment to the amplified central sub-area, wherein the various applications can be displayed in the mode of displaying icons of various applications.
At this time, the driver can view various displayed applications, perform gesture operation on the application which the driver wants to use, and execute operation content corresponding to the second gesture operation when the screen controller monitors the second gesture operation for the displayed application.
The second mode is as follows:
the control functions of the vehicle auxiliary driving integrated with the receiving sub-area and the control functions of the basic devices in the vehicle are integrated with the enlarged central sub-area 5, and at this time, the enlarged central sub-area 5 does not display any content. The driver may preset operation contents corresponding to each gesture operation, and when the driver performs the gesture operation on the enlarged central sub-area 5, the gesture operation is actually performed on the vehicle auxiliary driving control function integrated with the enlarged central sub-area 5 and the control function of the in-vehicle basic device. And when the screen controller monitors a third gesture operation aiming at the enlarged central sub-region, executing operation content corresponding to the third gesture operation.
Wherein the third gesture operation comprises at least one of:
the single finger, the double fingers and the multiple fingers slide transversely or longitudinally in the amplified central sub-area;
alternatively, the first and second electrodes may be,
marking specific letters in the amplified central sub-area by a single finger, double fingers and multiple fingers;
alternatively, the first and second electrodes may be,
the single finger, the double fingers and the multiple fingers slide clockwise or anticlockwise in the amplified central sub-area;
alternatively, the first and second electrodes may be,
and a single finger, a double finger and a plurality of fingers draw specific patterns in the amplified central sub-area.
Illustratively, the specific pattern may be a love pattern, a circle pattern.
For example: assuming that the operation content corresponding to the gesture operation of the two fingers sliding transversely in the central sub-area 5 is set as starting lane keeping by the driver, after integrating the vehicle auxiliary driving control function integrated with the storage sub-area and the control function of the in-vehicle basic equipment into the enlarged central sub-area 5, when the driver performs the gesture operation of the two fingers sliding transversely in the central sub-area 5 aiming at the enlarged central sub-area 5, the screen controller monitors the third gesture operation of the two fingers sliding transversely aiming at the enlarged central sub-area 5, and executes the operation content corresponding to the third gesture operation, namely starting lane keeping.
Therefore, when the first gesture operation of drawing from the storage subarea to the central subarea 5 is monitored, the central subarea 5 is enlarged to the preset size, and the peripheral subareas are reduced to the corresponding size, so that the storage subarea is unfolded when the fact that the driver has the operation intention is determined, and false triggering is avoided. And the control function of the vehicle auxiliary driving and the control function of the basic equipment in the vehicle can be operated through gesture operation, a touch screen does not need to be checked, and the driving safety is improved.
In one implementation manner, in the case that the display area is divided into the central sub-area 5 and the at least one peripheral sub-area 6, the steering wheel human-computer interaction method for the vehicle provided by the embodiment of the invention may further include:
when a fourth gesture operation that the first peripheral sub-region except the receiving sub-region is drawn to the central sub-region 5 is monitored, the central sub-region 5 is enlarged to a preset size, and each peripheral sub-region is reduced to a corresponding size;
displaying display content corresponding to the control function of the in-vehicle display device integrated with the first peripheral sub-region to the enlarged central sub-region 5;
when a fifth gesture operation of drawing from the enlarged central sub-region 5 to the first peripheral sub-region is monitored, the central sub-region is reduced to an initial size, each peripheral sub-region is enlarged to a corresponding size, and display content displayed in the central sub-region 5 is displayed to the first peripheral sub-region.
In order to use the functions integrated by the peripheral sub-regions other than the receiving sub-region, a driver needs to perform gesture operation of scribing from the first peripheral sub-region other than the receiving sub-region to the central sub-region 5, when the screen controller monitors a fourth gesture operation of scribing from the first peripheral sub-region other than the receiving sub-region to the central sub-region 5, it is known that the driver needs to use the functions integrated by the peripheral sub-regions other than the receiving sub-region, at this time, the central sub-region 5 is enlarged to a preset size, each peripheral sub-region is reduced to a corresponding size, and the driver can set the preset size.
Then, the display content corresponding to the control function of the in-vehicle display device integrated in the first peripheral sub-area is displayed to the enlarged central sub-area 5, for example: assuming that the control function of the in-vehicle display device integrated in the first peripheral sub-region is the control function of the digital instrument panel, the enlarged central sub-region 5 may display the display content of the digital instrument panel.
When the driver does not need to use the function integrated by the peripheral sub-regions except the accommodating sub-region, the gesture operation of drawing the enlarged central sub-region 5 to the first peripheral sub-region is performed, when the screen controller monitors the fifth gesture operation of drawing the enlarged central sub-region 5 to the first peripheral sub-region, the fact that the driver does not need to use the function integrated by the peripheral sub-regions except the accommodating sub-region is known, at this time, the central sub-region is reduced to the initial size, each peripheral sub-region is enlarged to the corresponding size, the original state is recovered, and the display content displayed in the central sub-region 5 is displayed to the first peripheral sub-region.
Therefore, by monitoring the gesture operation mode, the display content corresponding to the control function of the in-vehicle display device integrated with the first peripheral sub-region except the accommodating sub-region can be displayed to the enlarged central sub-region 5, and the checking convenience is improved.
When the in-vehicle display device integrated in the first peripheral sub-region is the central control screen, displaying the display content corresponding to the control function of the in-vehicle display device integrated in the first peripheral sub-region to the enlarged central sub-region may include:
judging whether the central control screen is in a default application icon display interface or not;
and if so, displaying the auxiliary driving application corresponding to the control function of the central control screen to the enlarged central subregion.
Because the applications that can be displayed by the central control screen are of various types, and the applications that can be used in the driving process are generally auxiliary driving applications, when the in-vehicle display device integrated in the first peripheral sub-region is the central control screen, it needs to be judged whether the central control screen is in a default application icon display interface, and if so, the auxiliary driving applications corresponding to the control function of the central control screen are displayed to the enlarged central sub-region 5.
For example, the driving assistance application may be a map application.
Therefore, when the central control screen is in the default application icon display interface, the auxiliary driving application corresponding to the control function of the central control screen is displayed to the amplified central sub-area 5, and the situation that driving safety is affected due to the fact that entertainment applications are displayed in the amplified central sub-area 5 is avoided.
In another implementation manner, in the case that the display area is divided into the central sub-area 5 and the at least one peripheral sub-area 6, the steering wheel human-computer interaction method for the vehicle provided by the embodiment of the invention may further include:
when a sixth gesture operation of drawing from the second peripheral subregion to a third peripheral subregion is monitored, displaying display content corresponding to a control function of the in-vehicle display device integrated with the second peripheral subregion on the in-vehicle display device integrated with the third peripheral subregion for displaying, wherein the second peripheral subregion and the third peripheral subregion are subregions except for the storage subregion.
When the driver wants to switch the display content of one in-vehicle display device to the display content of the other in-vehicle display device, the gesture operation of drawing from a second peripheral sub-area to a third peripheral sub-area is performed, wherein the second peripheral sub-area and the third peripheral sub-area are all sub-areas except for the accommodating sub-area. When the screen controller monitors a sixth gesture operation of drawing from the second peripheral subregion to the third peripheral subregion, it is known that the driver wants to display the display content corresponding to the control function of the in-vehicle display device integrated in the second peripheral subregion on the in-vehicle display device integrated in the third peripheral subregion for display, and at this time, the display content corresponding to the control function of the in-vehicle display device integrated in the second peripheral subregion is displayed on the in-vehicle display device integrated in the third peripheral subregion for display.
For example: assuming that the in-vehicle display device integrated in the second peripheral sub-region is a center control screen and the in-vehicle display device integrated in the third peripheral sub-region is a head-up display HUD display device, when the screen controller monitors a sixth gesture operation of drawing from the second peripheral sub-region to the third peripheral sub-region, display content corresponding to a control function of the center control screen is displayed on the head-up display HUD display device for display.
From this, through dividing the display area into a plurality of peripheral subregion 6, and set up the mode that each subregion integration has different display device in the car except that accomodating the subregion, can realize switching different display device's in the car display device's display content through gesture operation, make display device can show other display device's in the car display device's display content except that self corresponds display content, the display content that has realized different display device in the car is shown in coordination, the comfort and the science and technology that the driver looked over the display content have been promoted and are felt.
In another implementation manner, in the case that the display area is divided into the central sub-area 5 and the at least one peripheral sub-area 6, the steering wheel human-computer interaction method for the vehicle provided by the embodiment of the invention may further include:
when the vehicle is monitored to be in a static state, the vehicle gear is placed in the P gear, and the hand brake is pulled up, the limitation of the entertainment mode of the display area is removed;
when the gesture operation aiming at the central subarea is monitored, the central subarea is enlarged to a preset size, each peripheral subarea is reduced to a corresponding size, and entertainment applications are displayed on the enlarged central subarea;
when a zooming-out gesture aiming at the zoomed-in central subarea is monitored, or when the vehicle is monitored to be in a static state, the gear of the vehicle is placed in a P gear or at least one of the hand brakes is pulled up, the central subarea 5 is zoomed out to the initial size, each peripheral subarea is zoomed in to the corresponding size, entertainment applications are not displayed any more, and the display area is controlled to enter a working mode.
In order to improve the entertainment attribute of the vehicle in the static state, when the vehicle is monitored to be in the static state, the vehicle is placed in the P gear, and the hand brake is pulled up, the limitation of the entertainment mode in the display area is released, the driver is allowed to enter the entertainment mode in the display area, and at the moment, no content is displayed in the display area. When a driver needs to perform entertainment operation, the central sub-region 5 is subjected to amplification gesture operation, at the moment, when the screen controller monitors the amplification gesture operation aiming at the central sub-region 5, the central sub-region 5 is amplified to a preset size, each peripheral sub-region is reduced to a corresponding size, entertainment applications are displayed in the amplified central sub-region 5, and the driver clicks the displayed entertainment applications to perform entertainment applications.
Specifically, when a reduction gesture for the enlarged central sub-region 5 is monitored, or when the vehicle is monitored to be in a stationary state and the vehicle is placed in at least one of a P gear or a manual brake pull-up, the central sub-region is reduced to an initial size, each peripheral sub-region is enlarged to a corresponding size, the original state is restored, the entertainment operation is exited, the entertainment application is not displayed any more, the display region is controlled to enter the working mode, and at this time, the driver cannot enter the entertainment application through gesture operation.
Since the driver may also use the zoom-in gesture operation or the zoom-out gesture operation when operating the entertainment application, in order to distinguish the zoom-in gesture operation or the zoom-out gesture operation when the driver operates the entertainment application from the zoom-in gesture operation used for performing the entertainment operation and the zoom-out gesture operation used for exiting the entertainment operation, there may be clearly separate settings for the zoom-in gesture operation and the zoom-out gesture operation, respectively. For example: the zoom-in gesture operation used for performing the entertainment operation may be set as a two-finger zoom-in operation, the zoom-in gesture operation used for performing the zoom-in operation on the entertainment application may be set as a multi-finger zoom-in operation, the zoom-out gesture operation used for exiting the entertainment operation may be set as a two-finger zoom-out operation, and the zoom-out gesture operation used for performing the zoom-out operation on the entertainment application may be set as a multi-finger zoom-out operation.
Therefore, the mode that the vehicle is in a static state, the gear of the vehicle is placed in a P gear or a hand brake is pulled up is monitored, so that whether the display area enters an entertainment mode or exits the entertainment mode to enter a working mode is controlled, the central sub-area 5 is enlarged and reduced by gesture operation, and the entertainment of the vehicle is improved.
In another implementation manner, the steering wheel human-computer interaction method for the vehicle provided by the embodiment of the invention may further include:
receiving the light intensity sent by the light sensor;
and adjusting the brightness and the contrast of the display area according to the light intensity and a preset adjusting rule.
Because the luminous probably causes the interference to driver's driving process of touch screen, in order to reduce the interference, can install light sensor in the car, detect the light intensity in the car through light sensor, light sensor is connected with screen controller, light sensor sends the light intensity that detects to screen controller, screen controller receives the light intensity that light sensor sent, adjust luminance and the contrast in display area according to light intensity and preset regulation rule.
Wherein, adjust luminance and contrast of display area according to light intensity and preset regulation rule, can include:
when the light intensity exceeds a first preset light intensity, adjusting the brightness of the display area to a first preset brightness and adjusting the contrast to a first preset contrast;
when the light intensity is smaller than the second preset light intensity, the brightness of the display area is adjusted to a second preset brightness and the contrast is adjusted to a second preset contrast, wherein the first preset light intensity is larger than the second preset light intensity, the first preset brightness is larger than the second preset brightness, and the first preset contrast is larger than the second preset contrast.
That is, the brightness and contrast of the display area are increased when the vehicle is bright, and the brightness and contrast of the display area are decreased when the vehicle is dark.
Therefore, the interference of the light emission of the touch screen to the driving process of a driver is reduced by adjusting the brightness and the contrast of the display area according to the light intensity and the preset adjusting rule.
