Embodiment
In existing onboard system, because the various application services provided get more and more, the content that user interface shows also gets more and more thereupon, such as various application icon.On the one hand this extends the function of onboard system, but on the other hand, user interface displaying contents numerous and diverse, makes user by when such as the peripheral hardware such as keyboard or touch-screen carries out input operation, easily produce maloperation, because this reducing the operability of onboard system.More seriously, this also may cause producing potential traffic safety hidden danger.
The transport condition of vehicle is divided into different driving modes according to the driving information of vehicle by the embodiment of the present invention, and according to different driving modes, the display state of each application icon in corresponding adjustment user interface, make it easy to user click, thus the operability of onboard system and the security of vehicle traveling under improve different transport condition.
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
Embodiments provide a kind of method for displaying user interface of onboard system.Wherein, mobile unit can show user interface in several ways, such as, show user interface by touch screen displays.The embodiment of the present invention, by the display mode of touch screen displays, enables user directly with the mode input control order that touch screen is clicked, with convenient user operation.
With reference to Fig. 1, below by way of concrete steps, the embodiment of the present invention is described in detail.
Step S1. obtains the velocity information of vehicle.
In instantiation, acquisition speed information can be the instantaneous velocity being obtained vehicle by the monitoring system of vehicle, also can obtain the average velocity of vehicle in the first preset time period.User self-definedly as required can arrange the first preset time period T, such as 5 minutes.Compared to selecting the instantaneous velocity obtaining vehicle as the standard dividing driving states, select average velocity can improve the stability of user interface, vehicle is avoided also correspondingly constantly to change because the continuous change of instantaneous velocity causes user interface to show state, to improve Consumer's Experience.
In above-mentioned instantiation, the average velocity calculating vehicle in the first time period preset can have various ways.A kind of optional embodiment is, calculate the average velocity of vehicle in described first preset time period T1 in i-th time subsegment, described i-th time subsegment is the current time subsegment described preset time period be divided in N number of time subsegment, and i is natural number, and 1≤i≤N.When the average velocity difference of the average velocity of vehicle in described i-th time subsegment and last first preset time period T0 exceedes preset first threshold value, initial using described i-th time subsegment as the first new preset time period T1, calculate the average velocity of the first new preset time period T1.
Such as, the first preset time period T can be set to 5 minutes, and is divided into 5 time subsegments, i.e. N=5, makes each time subsegment t be 1 minute, and arrange first threshold is 10,000 ms/h simultaneously.With reference to figure 2, calculate vehicle at last first preset time period T0 with the speeds of 20,000 ms/h.If vehicle at the average velocity of each time subsegment of current first preset time period T1 compared with the average velocity of last first preset time period T0, velocity contrast is all not more than 10,000 ms/h of first threshold, then at this first preset time period T1 through later, calculate the average velocity in this first preset time period T1.If vehicle is in the subsegment sometime of current first preset time period T1, average velocity as the 3rd time subsegment t3 is more than or equal to 30,000 ms/h, then ignore the average velocity of time subsegment t1 and t2, initial using the initial time of time subsegment t3 as the first new preset time period T1, calculate the average velocity in a new round first preset time period T1, thus the situation of change of speed information can be reflected in time, to adjust user interface.
On the other hand, above-mentioned instantiation can also be avoided in driving conditions because emergency case causes speed to have an impact to acquisition speed information in the larger change of instantaneous generation.Such as, vehicle due to needs dodge road surface subside and take a sudden turn time.In this case, the change of speed is of short duration, and the average velocity in corresponding time subsegment, compared with the average velocity of last first preset time period T0, still within first threshold, therefore can ignore the of short duration change of the speed of a motor vehicle.And if the difference of the average velocity of time subsegment and last first preset time period T0 average velocity, beyond the scope of first threshold, then illustrate that the change of the speed of a motor vehicle is continuous and effective, therefore no longer with time subsegment t1 for calculating the initial time of the first preset time period T1, but with this time subsegment t3 for initial time, calculate the average velocity of a new round first preset time period T1.
The optional embodiment of another kind of above-mentioned instantiation is, with reference to figure 3, when the instantaneous acceleration of vehicle exceedes predetermined acceleration threshold value described in moment K a certain in described first preset time period T1, with described moment K for starting, calculate the average velocity in the second preset time period tx.When the average velocity difference of the average velocity of vehicle in described second preset time period t and last first preset time period T0 exceedes default Second Threshold, with the described moment for starting, calculate the average velocity of the first new preset time period.
Such as, the first preset time period T1 can be set to 5 minutes, and arranging acceleration rate threshold is 5 meter per seconds
2, Second Threshold is 10,000 ms/h, and to arrange the second preset time period t be 1 minute.Calculate vehicle at last first preset time period T0 with the speeds of 20,000 ms/h.If obtain vehicle a certain moment in this first preset time period T1 by the acceleration transducer of vehicle, the instantaneous acceleration being set to K is more than or equal to above-mentioned acceleration rate threshold 5 meter per second
2, then to calculate after this moment 1 minute, whether the average velocity difference of the average velocity namely in the second preset time period tx and last first preset time period T0 is greater than the scope of above-mentioned Second Threshold 10,000 ms/h.When being more than or equal to the scope of Second Threshold, with above-mentioned a certain moment K for starting, calculate the average velocity of a new round first preset time period; And if within the scope of Second Threshold, then still calculate the average velocity of the first preset time period with former initial time.
Travel acceleration by testing vehicle, the real-time change of the transport condition of vehicle can be obtained better.And compared by the average velocity of the average velocity in a period of time after being changed and previous time period, its effective duration can be judged, thus ignore the of short duration transient change of the speed of a motor vehicle.
Step S2. judges the driving mode that described velocity information is corresponding.
In instantiation, the driving mode of vehicle can be set as multiple according to velocity information, by the velocity information of vehicle is compared with the 3rd threshold value preset, judge that the threshold speed residing for velocity information is interval, the driving mode corresponding to threshold speed interval residing for velocity information can be judged.Adopt the 3rd above-mentioned threshold value, can be used for demarcation interval.Such as, 3rd threshold value can be 15 and 40, the threshold speed interval that the driving mode of low-speed running state is corresponding is 0,000 m/h-15 thousand ms/h, the threshold speed interval that the driving mode of state of driving at moderate speed is corresponding is 15,000 m/h-40 thousand ms/h, and the threshold speed interval that the driving mode of high-speed travel state is corresponding is more than 40,000 ms/h.
Be understandable that, in above-mentioned instantiation, according to practical application, driving mode can adopt other to classify and arrange corresponding threshold speed, and is not limited in above-mentioned classification.
Step S3. selects the display state of each application icon in described user interface according to described driving mode.
In instantiation, the display state of above-mentioned application icon can be display application icon, or not display application icon.Such as, driving mode comprises the first driving mode corresponding to friction speed interval and the second driving mode two class, when driving mode is the first driving mode, shows whole application icons on a user interface.And when driving mode is the second driving mode, the application icon of a display section on a user interface.Wherein, the speed of vehicle when the first driving mode is less than the speed when the second driving mode.The application icon display data that different driving modes is corresponding different.Which which have recorded each application icon in display data show in driving mode and do not show in driving mode.When driving mode changes, mobile unit will go to obtain corresponding display data, to adjust the display state of application icon.
On the basis of above-mentioned instantiation, described second driving mode can comprise at least two sub-driving modes.When described driving mode is a sub-driving mode in described second driving mode, described user interface shows default application icon.When described driving mode is b sub-driving mode in described second driving mode, the application icon that described user interface shows is less than the application icon shown in described user interface when described driving mode is described a sub-driving mode.Wherein, described second driving mode is divided into any two the sub-driving modes in M sub-driving mode by a, b, and a, b are natural number, and 1≤a≤M, 1≤b≤M, and a ≠ b; The speed of described vehicle when described a sub-driving mode is less than the speed when described b sub-driving mode.By the second driving mode being set to the multiple sub-driving mode in corresponding friction speed interval, correspond to different display data respectively, make the application icon in user interface along with the increase of speed, successively reduce, thus can user interface be simplified, be user-friendly to.
In a kind of Alternate embodiments, difference according to application program is classified, such as amusement class, navigation type, vehicle condition information monitoring class and communication class etc., for the importance of traffic safety, the display data of application icon can to different classes of application icon classification setting.When the first driving mode, display data are set to show all application icons on a user interface, as the application icon of all application programs such as refuelling station's navigation, parking ground navigation, the navigation of 4s shop, urgent call, music, Domestic News.And when the first sub-driving mode of the second driving mode, the only application icon of show navigator class, vehicle condition information monitoring class and communication class application program, when the second sub-driving mode of the second driving mode, only show the application icon of vehicle condition information monitoring class and communication class application program ..., thus make application icon along with the increase of the speed of a motor vehicle, successively reduce.
On the basis of above-mentioned instantiation, the driving mode of vehicle can also comprise the third line and sail pattern, and speed when described the third line sails pattern is greater than the described speed when the second driving mode.When described driving mode be the third line sail pattern time, described user interface only shows an application icon, such as the urgent call application icon that emergency communication uses, to make vehicle can tackle emergency case in time in case of the high-speed travel state, improve travel safety.
In another kind of instantiation, the display state of above-mentioned application icon can be amplify application icon or reduce application icon.Such as, when described driving mode is described first driving mode, maintenance application icon is original size, and when described driving mode is described second driving mode, application icon in described user interface is carried out amplification display.
The principle that realizes of above-mentioned instantiation is: the pantograph ratio setting application icon in the display data of the application icon of each driving mode corresponding, when making vehicle become form pattern at a high speed from the driving mode of low speed, amplify application icon, and when vehicle becomes the form pattern of low speed from driving mode at a high speed, reduce application icon.
In order to make application icon in the change of convergent-divergent, avoid icon overlap and keep the neat of user interface display, can also adjust the viewing area of each icon in display data, namely determine its new viewing area by the coordinate figure of adjustment icon on display interface.
Be understandable that, when not violating the technology of the present invention thought, above-mentioned various instantiation can combine mutually.Such as, when vehicle is along with the increase of speed, when its driving mode switches between each sub-driving mode of the second above-mentioned driving mode, successively can reduce the application icon of display and successively the application icon of display be amplified according to residing sub-driving mode, or successively increase the application icon of display and successively the application icon of display reduced according to residing sub-driving mode.And when vehicle be in above-mentioned the third line sail pattern time, namely described driving mode be corresponding top speed interval time, by application icon in described user interface, as the application icon for urgent call, be amplified to the display of whole user interface.
The embodiment of the present invention additionally provides the user interface display device of onboard system corresponding to above-mentioned method for displaying user interface, and with reference to Fig. 4, wherein, the user interface display device 1 of onboard system can comprise: acquiring unit 11, for obtaining the velocity information of vehicle; Judging unit 12, for judging the driving mode that described velocity information is corresponding; Selection unit 13, for selecting the display state of each application icon in described user interface according to described driving mode.
