Description

Technical Field

[0001] The present invention relates to the technical field of vehicle display themes, and in particular to a method and device for controlling an interface theme of a vehicle display terminal. Background Art

[0002] A vehicle is usually equipped with multiple vehicle display terminals for displaying different information. For example, the vehicle's combined instrument panel can display vehicle information such as vehicle speed, engine speed, in-vehicle temperature, fuel consumption, mileage, etc. in real time, so that the driver can understand the real-time status of the vehicle. In response to the huge competition in the vehicle market, many vehicle manufacturers have made improvements to the interior of the vehicle. More and more combined instrument panels use thin film transistor liquid crystal displays (TFT LCD), such as 10.25-inch LCD or 12.3-inch LCD. On this basis, vehicle manufacturers have designed a variety of interface themes (or skins) for combined instrument panels to make the combined instrument panel look more colorful and personalized. However, the interface themes developed by vehicle manufacturers usually need to be paid for, and most vehicle users do not like the charging method, which makes the interface displayed by the combined instrument panel monotonous, and the functions that the vehicle manufacturer has worked hard to develop may be difficult to be displayed on the vehicle display terminal. Therefore, there is an urgent need for a control method and device for the interface theme of a vehicle display terminal, which can provide interface themes to vehicle users through specific strategies without requiring vehicle users to pay.

[0036] The implementation scheme of the present invention is described in detail below. This implementation scheme is implemented on the premise of the technical scheme of the present invention, and a detailed implementation method and specific operation process are given, but the protection scope of the present invention is not limited to the implementation scheme described below.

[0037] According to an embodiment of the present invention, a vehicle display terminal may be configured to have a theme setting interface and store a plurality of theme interface images. The theme setting interface may be configured to have a selection button for a theme interface image that is in a one-to-one correspondence with the theme interface image, and to display the selection buttons for all theme interface images. The theme setting interface may be implemented through a user settings menu (USM) in an audio, video, navigation and telematics (AVNT) system.

[0038] Figure 1 The theme setting interface is shown as an example. Figure 1 As shown, the theme setting interface shows selection buttons for selecting theme interface pictures: "Default", "Skin A", "Skin B", "Skin C", "Skin D" and "Skin E", where A, B, C, D and E represent different interface themes (or skins). Figure 1In the shown theme setting interface, the selection button "Default" has been selected by default, and each selection button corresponds to a set of theme interface pictures. Figure 2 The following example shows the theme interface picture corresponding to the selection button "Default". Figure 2 As shown, the default theme interface picture only shows the road, making the interface of the vehicle display terminal very monotonous.

[0039] At this time, the vehicle display terminal can only use the default theme interface picture, and the vehicle user cannot select these selection buttons "Skin A", "Skin B", "Skin C", "Skin D" and "Skin E" to use other colorful interface themes (or skins). The control method of the interface theme of the vehicle display terminal according to the embodiment of the present invention enables the selection buttons "Skin A", "Skin B", "Skin C", "Skin D" and "Skin E" except "Default" among the selection buttons to be activated so that they can be selected in the theme setting interface.

[0040] Figure 3 FIG. 1 is a general flow chart of a method for controlling an interface theme of a vehicle display terminal according to an embodiment of the present invention. Figure 3 As shown, the control method of the interface theme of the vehicle display terminal according to the embodiment of the present invention includes: obtaining the driving data of the vehicle user during the driving process (S100). According to the obtained driving data and the pre-set score evaluation mechanism, the driving behavior score of the vehicle user is calculated (S200). Determine whether the calculated driving behavior score reaches a predetermined value (S300); and when it is determined that the driving behavior score reaches the predetermined value ("Yes" of S300), enable any one of the multiple theme interface pictures to be selected through the theme setting interface (S400), that is, enable any one of the selection buttons of the theme interface picture except the default one to be selected in the theme setting interface.

[0041] Therefore, according to an embodiment of the present invention, an interface theme (or skin) can be provided to a vehicle user through a specific strategy without requiring the vehicle user to pay. In this strategy, the driving behavior of the vehicle user needs to be evaluated. Only when the driving behavior score of the vehicle user meets the conditions (i.e., reaches a predetermined value), can the interface theme be provided to the user as a reward.

[0042] Figure 4 FIG. 1 is a detailed flow chart of a method for controlling an interface theme of a vehicle display terminal according to an embodiment of the present invention. Figure 4As shown, in a specific embodiment, when the driver starts the vehicle to start a driving trip, the current driving behavior score is equal to the driving behavior score at the end of the previous driving trip (S10). Subsequently, the driving data of the vehicle user during this driving process is obtained. The driving data may include the average fuel economy parameter value of the vehicle, the number of new traffic violations in the vehicle, and information about whether the driver is in a fatigue driving state. These driving data can respectively reflect fuel economy, road civility and driving safety.

[0043] Obtaining the average fuel economy parameter value of the vehicle during the driving process may include: collecting the fuel consumption and the driving distance of the vehicle during a driving trip (S11). And calculating the average fuel economy parameter value according to the fuel consumption and the driving distance of the vehicle during the driving trip (S12). That is, the average fuel economy parameter value can be calculated by the following formula:

[0044] Average fuel economy parameter value (L / 100km) = fuel consumption (L) × 100 ÷ mileage (km).

[0045] For example, if the vehicle travels 50 km during this driving trip and the fuel consumption is 4 L, the average fuel economy parameter of the vehicle is calculated to be 4 L × 100 ÷ 50 km = 8 L / 100 km. The above collection and calculation steps can be implemented through the combined instrument panel.

[0046] Acquiring the number of new traffic violations that occurred during the driving process of the vehicle may include: collecting the cumulative number of traffic violations of the vehicle at intervals of a predetermined time period (S13), calculating the difference between the cumulative number of traffic violations collected twice adjacently (S17), that is, calculating the difference between the cumulative number of violations collected next time and the cumulative number of violations collected this time, and using the difference as the number of new traffic violations that occurred in the vehicle. Specifically, the cumulative number of traffic violations of the vehicle may be collected from an application software for public transportation services. The application software for public transportation services records vehicle information, the cumulative number of traffic violations of the vehicle, each traffic violation (e.g., license plate violation, red light violation, violation of not wearing a seat belt, illegal parking violation, violation of driving against the lane, etc.) and corresponding penalties. For example, the above application software may be the "Internet Traffic Safety Comprehensive Service Management Platform of the Ministry of Public Security" or other databases storing the cumulative number of traffic violations. The application software may be configured in the AVNT system of the vehicle.

[0047] In addition, whether the driver is in a fatigue driving state can be determined by a driver attention warning (DAW) unit in an advanced driving assistance system (ADAS) (S14). Specifically, the DAW unit can determine whether the vehicle crosses the line and drives unstably through a front camera, etc., thereby determining whether the driver is in a fatigue driving state.

[0048] Next, the driving behavior score of the vehicle user is calculated based on the acquired driving data and the pre-set score evaluation mechanism (S200). For example, the driving behavior score can be calculated based on the average fuel economy parameter value of the vehicle, the number of traffic violations committed by the vehicle, and whether the driver is in a fatigued driving state.

[0049] According to an embodiment of the present invention, the calculated average fuel economy parameter value is compared with the preset optimal vehicle fuel economy parameter value (S15). When the average fuel economy parameter value of the vehicle is less than or equal to the preset optimal vehicle fuel economy parameter value ("Yes" of S15), the driving behavior score is increased, for example, the driving behavior score is increased by 1 (S19). When the average fuel economy parameter value of the vehicle is greater than the preset optimal vehicle fuel economy parameter value ("No" of S15), the current driving behavior score is not changed (S16). Those skilled in the art can preset the optimal vehicle fuel economy parameter value according to the vehicle type. For example, the optimal vehicle fuel economy parameter value can be 4.7L / 100km. When the average fuel economy parameter value of the vehicle during this driving trip is calculated to be 8L / 100km, since 8L / 100km is greater than 4.7L / 100km, the vehicle user does not get points for saving fuel during this driving trip.

[0050] According to an embodiment of the present invention, it is determined whether the number of new traffic violations occurring in the vehicle (i.e., the above-mentioned difference) is equal to 0 (S18). When the difference is equal to 0 ("Yes" of S18), the current driving behavior score is not changed (S16). When the difference is not equal to 0 ("No" of S18), the driving behavior score is reduced by a value related to the difference, for example, the driving behavior score is reduced by the difference (S21).

[0051] According to an embodiment of the present invention, when it is determined that the driver is in a fatigue driving state ("yes" of S14), the driving behavior score is reduced, for example, the driving behavior score is reduced by 1 (S20). When it is determined that the driver is not in a fatigue driving state ("no" of S14), the current driving behavior score is not changed (S16). In addition, when it is determined that the driver is in a fatigue driving state, a warning message can be displayed on the interface of the vehicle display terminal. Figure 5 The interface of the vehicle display terminal is exemplarily shown in the case where it is determined that the driver is in a fatigue driving state. Figure 5 As shown, a warning message can be displayed in the interface of the vehicle display terminal to remind the driver to take a rest as soon as possible.

[0052] The above-mentioned score evaluation mechanism according to the implementation scheme of the present invention sets the same weight for driving data reflecting fuel economy, road civility and driving safety. However, the present invention is not limited to this, and different weights can be set for driving data. For example, if a vehicle user achieves fuel saving once, 1 point can be added. On the contrary, if road violations and fatigue driving occur, 2 points can be deducted respectively.

[0053] During the above calculation step, it is determined whether the driving behavior score reaches a predetermined value, for example, the predetermined value may be 10 (S22). When the driving behavior score is equal to 10 ("Yes" in S22), it indicates that the driving behavior of the vehicle user is good, so that the interface theme can be provided to the user as a reward, that is, any one of the multiple theme interface pictures can be selected (S24). Since the theme interface picture and the corresponding selection button are in a one-to-one correspondence, the selection button corresponding to the theme interface picture that can be selected can be made into a selection button that can be selected.

[0054] Figure 6 is a schematic diagram of a theme setting interface, that is, a schematic diagram of a theme setting interface when the driving behavior score of a vehicle user reaches a predetermined value. Figure 1 In the theme setting interface shown, the selection button "Skin A" cannot be selected. On the contrary, after the vehicle user's driving behavior score reaches a predetermined value, Figure 6 In the theme setting interface shown, the selection button "Skin A" can be selected.

[0055] According to the embodiment of the present invention, after any one of the multiple theme interface pictures can be selected (S24), it is determined whether the corresponding selection button is selected (S25), and in response to the corresponding selection button being selected ("Yes" in S25), the interface theme of the vehicle display terminal can be set to the corresponding theme interface picture (S26). Therefore, the vehicle user can set the interface theme of the vehicle display terminal by selecting the selection button "Skin A" in the theme setting interface. Figure 7 The theme interface picture corresponding to the selection button "Skin A" is shown as an example. Figure 7 and Figure 2 In comparison, the interface of the vehicle display terminal has become colorful and personalized.

[0056] Correspondingly, if the corresponding selection button is not selected (“No” in S25), that is, the vehicle user does not select the selection button “Skin A”, the theme interface of the vehicle display terminal remains unchanged. Figure 2 The default theme interface picture (S27) is shown.

[0057] After the driving behavior score reaches a predetermined value ("Yes" in S22), when any one of the multiple theme interface pictures can be selected (S24), the control method of the interface theme of the vehicle display terminal according to the embodiment of the present invention initializes the driving behavior score to zero (S23), so that the driving data can be re-acquired, and the driving behavior score of the vehicle is calculated according to the acquired driving data and the pre-set score evaluation mechanism (S11 to S22), so that any other theme interface picture can be selected. The next selection button corresponding to the theme interface picture that can be selected can be "Skin B". In one example, according to the embodiment of the present invention, the selection button "Skin A", the selection button "Skin B", the selection button "Skin C", the selection button "Skin D" and the selection button "Skin E" can be activated sequentially, so that these selection buttons "Skin A", "Skin B", "Skin C", "Skin D" or "Skin E" can be selected in the theme setting interface. Finally, due to the safe and civilized driving habits of the vehicle user, all the selection buttons can be selected in the theme setting interface.

[0058] According to an embodiment of the present invention, the driving behavior score can be displayed in the form of a graphic image on the interface of the vehicle display terminal. For example, the driving behavior score can be displayed in the shape of a star. FIG. 8A to FIG. 8D The interface image showing the driving behavior score in the shape of stars is shown. One star is obtained for every 2 points of driving behavior score, and half a star is obtained for every 1 point of driving behavior score. Fig. 8A As shown in , the vehicle user achieved 6 fuel savings, 1 road violation, and no fatigue driving, so the vehicle user's driving behavior score is 5, so it can get two stars and half a star. Figure 8B As shown, the vehicle user achieved 12 fuel savings and had 1 road violation and 1 fatigue driving, so the vehicle user's driving behavior score is 10, so five stars can be obtained.

[0059] According to an embodiment of the present invention, when it is determined that the driving behavior score reaches a predetermined value, that is, when five stars are obtained, a reminder message is displayed on the interface of the vehicle display terminal, wherein the reminder message indicates that one of the selection buttons of the theme interface picture can be selected. For example, Figure 8C A reminder message "Congratulations, you have obtained a new skin" is displayed. Such a reminder message can be maintained for a certain period of time (for example, it can be maintained for 4 seconds), or it can be continuously displayed for multiple times (for example, continuously reminding within a week). If the vehicle user does not respond to the reminder message within the reference time, the reminder message is closed.

[0060] like Fig.8D As shown, after the driving behavior score gets five stars and the reminder message is closed, the driving behavior score is reset to 0 stars.

[0061] According to another embodiment of the present invention, a control device for an interface theme of a vehicle display terminal is provided. The vehicle display terminal is configured to have a theme setting interface, and the control device for the interface theme of the vehicle display terminal includes an acquisition unit, a score calculation unit, and a control unit. The acquisition unit can be configured to acquire driving data of a vehicle user during a driving process. The score calculation unit can be configured to calculate a driving behavior score of a vehicle user during a driving trip based on the acquired driving data and a preset score evaluation mechanism. The control unit can be configured to determine whether the calculated driving behavior score reaches a predetermined value, and when it is determined that the driving behavior score reaches the predetermined value, enable any one of a plurality of theme interface pictures to be selected through the theme setting interface.

[0062] In a specific embodiment, the driving data includes an average fuel economy parameter value of the vehicle, a number of new traffic violations in the vehicle, and information on whether the driver is in a fatigue driving state.

[0063] The acquisition unit collects the fuel consumption and the driving distance of the vehicle in one driving trip, and is capable of calculating an average fuel economy parameter value according to the fuel consumption and the driving distance of the vehicle in one driving trip.

[0064] The cumulative number of traffic violations collected by the vehicle at a unit interval predetermined time period is obtained, the difference between the cumulative number of traffic violations collected twice adjacently is calculated, and the difference is used as the number of new traffic violations occurring in the vehicle.

[0065] The acquisition unit can collect information on whether the driver is in a fatigue driving state from the DAW unit included in the ADAS.

[0066] The integral calculation unit is configured to increase the driving behavior score when the calculated average fuel economy parameter value of the vehicle is less than or equal to the preset optimal vehicle fuel economy parameter value; reduce the driving behavior score by a value related to the number of new traffic violations in the vehicle when the calculated number of new traffic violations in the vehicle is not zero; and reduce the driving behavior score when it is determined that the driver is in a fatigue driving state. The integral calculation unit is further configured to initialize the driving behavior score to zero after determining that the driving behavior score reaches a predetermined value, reacquire the driving data of the vehicle user during the driving process, and recalculate the driving behavior score of the vehicle user.

[0067] The theme setting interface is configured with a selection button corresponding to the theme interface picture. The control device of the interface theme of the vehicle display terminal may further include a display unit. The display unit may be configured to: after any one of the multiple theme interface pictures is selected, in response to the corresponding selection button being selected, set the interface theme of the vehicle display terminal to the corresponding theme interface picture. The display unit may be further configured to: when it is determined that the driver is in a fatigue driving state, the interface of the vehicle display terminal displays a warning message. When it is determined that the driving behavior score reaches a predetermined value, the interface of the vehicle display terminal displays a reminder message, wherein the reminder message indicates that any one of the theme interface pictures can be selected. In addition, the display unit may be configured to display the driving behavior score in the form of a graphic image on the interface of the vehicle display terminal.

[0068] Fig. 9 1 is a block diagram of a system to which a control device of an interface theme of a vehicle display terminal according to an embodiment of the present invention is applied. Fig. 9 As shown, the AVNT system includes application software for public transportation services and USM. The combined instrument panel includes a driving information calculation module and a skin management module. ADAS includes a DAW unit.

[0069] The theme setting interface of the vehicle display terminal can be realized by the USM in the AVNT system. The interface of the vehicle display terminal can be the interface of the combined instrument panel.

[0070] The acquisition unit mentioned above can be implemented by the combined instrument panel, the AVNT system and the ADAS. The storage unit (not shown) included in the combined instrument panel stores the fuel consumption and the driving distance of the vehicle during the driving trip, so the acquisition unit can collect the fuel consumption and the driving distance of the vehicle during a driving trip through the storage unit of the combined instrument panel. Subsequently, the calculation of the average fuel economy parameter value in the acquisition unit can be implemented by the driving information calculation module included in the combined instrument panel. The application software for traffic public services records the vehicle information, the cumulative number of traffic violations of the vehicle, the behavior of each traffic violation and the corresponding punishment. The combined instrument panel can collect the cumulative number of traffic violations of the vehicle from the application software for traffic public services, and calculate the difference between the cumulative number of traffic violations collected twice adjacently, and use the difference as the number of new traffic violations in the vehicle. The DAW unit included in the ADAS can determine whether the driver is in a fatigue driving state, and the combined instrument panel can collect information about whether the driver is in a fatigue driving state from the DAW unit.

[0071] The integral calculation unit and the control unit may be implemented by a skin management module included in the combined instrument panel. The skin management module calculates the driving behavior score of the vehicle user based on the acquired driving data and a pre-set score evaluation mechanism. The skin management module determines whether the calculated driving behavior score reaches a predetermined value. When it is determined that the driving behavior score reaches the predetermined value, the skin management module enables any one of a plurality of theme interface images to be selected through a theme setting interface. In response to the corresponding selection button being selected, the skin management module sets the interface theme of the vehicle display terminal to the corresponding theme interface image. Finally, the vehicle user can obtain the desired combined instrument panel skin.

[0072] In a specific example, the combined instrument panel communicates with the AVNT system via the MM-CAN bus, and the combined instrument panel communicates with the ADAS via the C-CAN bus.

[0073] The control method and device of the interface theme of the vehicle display terminal according to the implementation scheme of the present invention can provide the interface theme to the vehicle user through a specific strategy without the vehicle user having to pay. The vehicle user can obtain a new display theme (for example, a combined instrument panel skin) through this strategy, and can select a new combined instrument panel skin or maintain the default skin. In this way, the interface of the combined instrument panel can be made to look more colorful and personalized. In addition, in order to obtain the desired combined instrument panel skin, the vehicle user needs to pay more attention to driving and carefully abide by traffic rules, which may gradually develop safe and civilized driving habits and improve road traffic safety.
