An embodiment of the onboard HMI adjustment method of the present invention is explained below in conjunction with the hardware environment shown in fig. 1.
Referring to fig. 2, fig. 2 is a schematic flow chart of a vehicle HMI adjustment method according to an embodiment of the invention.
The vehicle-mounted HMI adjusting method comprises the following steps S1 to S3, wherein the steps are detailed as follows:
step S1, acquiring the current distance from human eyes to the vehicle-mounted HMI screen, and calculating the distance variation according to the initial distance from the human eyes to the vehicle-mounted HMI screen and the current distance;
generally, an automobile may be driven by different drivers at different time periods, and heights of the drivers are different, so that the driver usually needs to adjust a seat before driving the automobile so as to obtain a proper driving posture, and after the seat is adjusted back and forth, a distance between eyes of the driver and a vehicle-mounted HMI screen is changed, that is, a certain difference value is usually generated between a current distance and an initial distance.
In the embodiment, the current distance from the human eye to the vehicle-mounted HMI screen can be acquired through a camera image recognition algorithm or an infrared sensor, and the initial distance from the human eye to the vehicle-mounted HMI screen can be acquired and set through testing in advance. When the automobile leaves the factory, the position of the driving position of the automobile is fixed, the factory position of the driving position of the automobile can be set as the initial position of the driving position, a model with the height of 1.7 m is selected for measurement, and when the model is located at the initial position of the driving position and sits well according to the driving posture, the distance between the eyes of the model and the vehicle-mounted HMI screen can be set as the initial distance. And the initial font size of the display content of the vehicle-mounted HMI screen is the size matched with the initial distance from human eyes to the vehicle-mounted HMI screen.
After the current distance from the human eyes to the vehicle-mounted HMI screen is obtained, the distance variation is calculated according to the current distance and the initial distance, namely, the difference between the current distance and the initial distance can be calculated, and therefore the distance variation can be calculated.
Step S2, acquiring the current vehicle speed;
when a vehicle is driven, the driver focuses on the front of the road, and as the vehicle speed increases, the distance ahead which the driver watches increases almost in proportion to the vehicle speed, but the view angle decreases almost in inverse proportion to the vehicle speed. When the view angle of the driver is narrowed, it is also difficult to see the display content on the screen of the vehicle-mounted HMI, and therefore it is also necessary to adjust the font size of the vehicle-mounted HMI according to the vehicle speed so that the driver can quickly see the display content on the screen.
In the embodiment, the current speed CAN be obtained through the automobile CAN bus according to a set time period; or the vehicle-mounted GPS can be used for acquiring the position information according to a set time period and acquiring the current vehicle speed according to the position change; in general, a mobile terminal such as a mobile phone or a tablet disposed in a vehicle is stationary relative to the vehicle body, and therefore the current vehicle speed can be obtained through the in-vehicle mobile terminal GPS according to a set time period. In order to ensure the accuracy of the vehicle speed, the vehicle speed can be acquired through a plurality of different channels, and the current vehicle speed is obtained by comprehensively processing the vehicle speeds acquired through the different channels.
Step S3, adjusting the font and the font size of the vehicle-mounted HMI according to the distance variation from the human eyes to the vehicle-mounted HMI screen and the current vehicle speed;
in this embodiment, please refer to fig. 3, wherein fig. 3 is a flowchart illustrating a step S3 of the vehicle HMI adjusting method according to the embodiment of the invention.
The step S3 includes the following steps:
step S31: acquiring an initial font size of key information of the vehicle-mounted HMI; the key information is information which needs to be concerned by a user in the driving process;
in this embodiment, the method for obtaining the font size of the initial font comprises: the method is characterized in that the method comprises the steps that a driver with the height of 1.7 m is measured when the driver is located at the initial position of a driving position of an automobile, when the automobile does not run, the distance from eyes of the driver to a vehicle-mounted HMI screen is the initial distance, and when the font on the screen is adjusted to enable the driver to see clearly the content on the screen, the font and the font at the moment are the initial font and the font.
Step S32: calculating a first font size variable quantity generated due to the distance change of the human eyes according to the distance variable quantity from the human eyes to the vehicle-mounted HMI screen and the initial font size;
in this embodiment, in the step S32, the method for calculating the variation of the first font size caused by the variation of the distance between the human eye and the vehicle-mounted HMI screen according to the variation of the distance between the human eye and the vehicle-mounted HMI screen includes: performing product operation on the distance variable from the human eyes to the vehicle-mounted HMI screen and the distance font size change factor to obtain a first font size variable; and the distance font size change factor is obtained according to the relevance test of the font size and the distance.
In this embodiment, the method for testing the association between the font size and the distance includes: the distance character size change factor is obtained by testing the relevance between the character size and the distance of a driver with the height of 1.7 m, and can be adjusted according to the actual effect. Specifically, when the vehicle speed is 0km/h, namely in a parking state, a driver with the height of 1.7 m actually watches the vehicle-mounted HMI interface at an initial driving position, records the distance from human eyes to a vehicle-mounted HMI screen, adjusts the current font size to be the size when the driver can clearly view the font on the HMI interface, records the current font size and takes the font size as the initial font size. And then moving the driver seat forwards or backwards to change the distance from the human eyes to the screen of the vehicle-mounted HMI, and measuring the distance from the current human eyes to the screen of the vehicle-mounted HMI through a sensor when a driver with the height of 1.7 m increases the corresponding word size according to the actual requirement so as to clearly see the fonts of key messages on the HMI interface. Through the scheme, the distance from human eyes to a screen of the car machine, namely the distance word size change factor can be obtained when the font word size needs to be increased by 1pt (namely one point). The distance font change factor a1 is 1 pt/(eye distance after changing seat position-eye initial distance), such as pt/100 mm.
Step S33: calculating the second font size variable quantity generated by the change of the vehicle speed according to the current vehicle speed and the initial font size;
in this embodiment, in step S33, the method of calculating the second font size variation amount generated by the vehicle speed variation according to the current vehicle speed and the initial font size includes: calculating the second font size variable quantity by performing product operation on the current vehicle speed and a vehicle speed font size change factor; and the vehicle speed font size change factor is obtained according to the relevance test of the font size and the vehicle speed.
The vehicle speed font size change factor is obtained by testing the relevance between the font size and the vehicle speed of a driver with the height of 1.7 m, and can be adjusted according to the actual effect. Specifically, a driver with the height of 1.7 m simulates driving to change the test vehicle speed, and when the corresponding word size is increased according to actual needs so as to clearly see the font of the key message on the HMI interface, the current vehicle speed is obtained through the measured CAN bus. Through the scheme, the variable quantity of the vehicle speed, namely the vehicle speed font size change factor, can be obtained when the font size needs to be increased by 1pt (namely one point). The vehicle speed character size change factor b1 is 1 pt/vehicle speed, such as 1pt/20 km/h.
Step S34: and performing operation on the initial font size, the first font size variable quantity and the second font size variable quantity of the key information of the vehicle-mounted HMI to calculate a target font size, and adjusting the initial font size of the key information of the vehicle-mounted HMI to the target font size.
For example, the initial font size is 22 pt; the variation of the first font size obtained by calculation is 4pt, namely 4 points; the calculated variation of the second font size is 10pt, namely 10 points, so that the point number of the changed font size is 22pt +4pt +10pt equal to 36pt, and the font size corresponding to 36pt is small, the target font size of the key information of the vehicle-mounted HMI is small, so that the initial font size of the key information of the vehicle-mounted HMI is adjusted to be small, at the moment, a driver can clearly see the content of the key information on the HMI interface, can quickly read the information, and cannot influence the driving safety.
In an optional embodiment, in step S34, after the initial font size of the key information of the vehicle-mounted HMI is adjusted to the target font size, the font size of the key information of the vehicle-mounted HMI is maintained for a preset duration.
The font size duration is set to prevent the problem that the driver cannot see the content of the key information clearly because the font size of the key information on the HMI interface is changed continuously due to the fact that the speed is changed continuously in the driving process of the vehicle. After the font size is set for a certain duration, the font size cannot change within a certain time, so that the driver can see the content of the key information of the vehicle-mounted HMI clearly during driving measurement, and the driving experience is improved.
In an optional embodiment, in step S34, after adjusting the initial font size of the key information of the vehicle HMI to the target font size, the method may further include the steps of: and acquiring a human eye focus, judging whether the human eye focus falls on the screen, and forbidding to adjust the font size of the key information of the vehicle-mounted HMI when the human eye focus falls on the screen.
The human eye focus can be obtained according to the human eye tracking module, and whether the human eye focus falls on the screen or not is judged through an eyeball tracking technology. When the human eye focus falls on the screen, the font and the word size of the key information of the vehicle-mounted HMI are forbidden to be adjusted, namely when a driver needs to check the information on the vehicle-mounted HMI interface, when the human eye focus is transferred to the vehicle-mounted HMI screen, the font and the word size of the key information of the HMI interface are not adjusted any more, but are adjusted after the sight of the driver leaves, so that the method is favorable for the driver to clearly see the content of the key information of the vehicle-mounted HMI during driving measurement, and the driving experience is improved.
In an alternative embodiment, after step S3, the method further includes the steps of: judging whether the current vehicle speed exceeds a preset font adjusting vehicle speed threshold value, and if the current vehicle speed exceeds the preset font adjusting vehicle speed threshold value, thickening and/or adjusting the font of the key information of the vehicle-mounted HMI into a color with high identification degree.
The font adjusting vehicle speed threshold is obtained according to a driving test, and can be 50 km/h; the font thickness adjustment quantity of the key information of the vehicle-mounted HMI is also obtained according to a driving test; and the color with high identification degree can be a more vivid color such as red or orange, so that the driver can more clearly read the content of the key information of the HMI interface, and the driving safety is improved.
Referring to fig. 4 and 5, fig. 4 is a schematic diagram illustrating an effect of a key information font size before adjusting the key information font size of the vehicle HMI according to the embodiment of the present invention; fig. 5 is a schematic diagram illustrating an effect of adjusting a font size of a key information font of the vehicle HMI according to the embodiment of the present invention.
In the display interface of the vehicle-mounted HMI, the font size of the font of the key information before font adjustment is smaller, the stroke is thinner, and the color is the conventional color, namely black. In the driving process, as the distance from human eyes to the vehicle-mounted HMI screen changes and the vehicle speed changes continuously, the driver needs to focus on the screen for a long time with high attention to see the key information clearly. Such as the name of the song, the name of the singer, and the name of the album shown in the figure. After the fonts are adjusted, the fonts and the word sizes of the key information are large, the strokes are thick, and the fonts are red, so that a driver can easily see the content of the key information on the vehicle-mounted HMI screen clearly in the driving process.
Referring to fig. 6 and 7, fig. 6 is a schematic diagram illustrating a prompt effect after the vehicle-mounted HMI receives information according to the embodiment of the present invention; fig. 7 is a schematic diagram illustrating a message content display effect after the vehicle-mounted HMI receives the information according to the embodiment of the present invention.
In an optional embodiment, when the vehicle-mounted HMI receives the short message, whether a human eye focus falls on a vehicle-mounted HMI screen is judged, when the human eye focus falls on the vehicle-mounted HMI screen, whether the vehicle-mounted HMI screen is opened is judged, and if the vehicle-mounted HMI screen is opened, a message content display window pops up; and if the vehicle-mounted HMI screen is closed, lightening the screen, popping up a message content display window, and closing the message content display window and the screen when the human eye focus leaves the screen.
When the vehicle-mounted HMI receives the short message, the vehicle-mounted HMI sends out message prompt tones through the loudspeaker, and after hearing the message prompt tones, the driver turns the head to look at the vehicle-mounted HMI screen if necessary. When the human eye focus falls on the vehicle-mounted HMI screen, judging whether the vehicle-mounted HMI screen is opened, if the vehicle-mounted HMI screen is opened, popping up a message content display window to display message content; and if the vehicle-mounted HMI screen is closed, lightening the screen, popping up a message content display window, and closing the message content display window and the screen when the human eye focus leaves the screen.
