Description

Vehicle cluster and its control system and method {Cluster of vehicle, system and method for controlling the cluster}

The present invention relates to vehicle clusters. More specifically, it relates to a vehicle cluster and its control system and method for controlling the display screen configuration of the vehicle cluster in response to app type information of a smartphone app running using the display of the vehicle cluster.

A vehicle cluster is a device that provides drivers with necessary vehicle status information at a glance.

The vehicle cluster basically displays the speedometer, engine rpm, engine temperature, and fuel gauge, as well as various indicators including turn signal indicators, light on indicators, and transmission position indicators, engine oil pressure warning lamp, battery charge warning lamp, airbag warning lamp, Warning lights indicating vehicle abnormalities, including engine warning light, coolant temperature warning light, ABS (anti-lock brake system) warning light, tire pressure (TMPS) warning light, and VDC (Vehicle Dynamic Control) warning light, as well as seat belt not worn warning light, brake warning light, and fuel shortage. Displays warning lights that require driver action, including warning lights, washer fluid level warning lights, door open warning lights, trunk open warning lights, and immobilizer warning lights.

Since the vehicle cluster displays vehicle status information necessary for safe operation of the vehicle, it is very important to configure it so that the driver can quickly and accurately recognize it intuitively.

In addition, recently, various equipment (cameras, sensors, etc.) has been installed in vehicles to further improve the safe operation of vehicles and provide various conveniences. Accordingly, safety information and convenience information generated from these devices are also stored in the vehicle cluster. The need for labeling is increasing.

However, it is practically impossible for existing analog clusters to display safety information and convenience information due to space limitations.

Therefore, in order to solve these problems, it has recently been replaced by digital clusters.

The digital cluster can display various information, including safety information and convenience information, as well as the vehicle status information described above, through a flat panel display.

In particular, the application of digital clusters to future-oriented vehicles, including autonomous vehicles and eco-friendly vehicles, is accelerating.

As an example, a representative example would be to display information obtained through ADAS (Advanced Driver Assistance System), which is being applied to vehicles in the era of autonomous driving, through a digital cluster. ADAS includes automatic emergency braking (AEB) system, lane departure warning system (LDWS), lane keeping assist system (LKAS), and blind spot detection (BSD) system.

In order to provide such diverse information, the size of flat panel displays is also increasing.

Accordingly, the display of the digital cluster not only conveys safety information such as lane maintenance easily, clearly, and intuitively through graphics, but also provides visual enjoyment by changing the display screen of the digital cluster to suit the driving environment. Additionally, you can enjoy navigation and various multimedia contents through the digital cluster display.

In this way, existing vehicles were a simple means of transportation, but recently, vehicles have been transformed into a space where various contents can be enjoyed.

Meanwhile, the environment for executing content has recently become more diverse, such as in vehicles, but it is no exaggeration to say that most content in everyday life is executed using smartphones. In other words, virtually all online activities are centered around smartphones.

Accordingly, various service technologies linking digital clusters and smartphones are being introduced recently.

Since the screen size of a smartphone is relatively small compared to the screen size of a digital cluster, an example is screen mirroring technology, which transmits and shares the screen of a smartphone to the screen of a digital cluster.

Representative examples of screen mirroring technology include Android Auto and Apple CarPlay, which connect a digital cluster and a smartphone wired or wirelessly and allow apps installed on the smartphone to be used in the digital cluster.

When the digital cluster and smartphone are connected and Android Auto and Apple CarPlay are running, the digital cluster's display screen is replaced by the smartphone's screen. In other words, the smartphone's operating system runs in the foreground, and the digital cluster's operating system runs in the background to change the screen.

Accordingly, when Android Auto and Apple CarPlay are running, only some safety information related to safety among vehicle status information is displayed or temporarily displayed in some areas of the display of the digital cluster. In other words, when Android Auto and Apple CarPlay are running, only a small number of essential information, including vehicle speed information, are displayed, so the main functions (safety and convenience) of the digital cluster are substantially lost.

In this way, when different operating systems that run independently share the display of the digital cluster, another operating system (smartphone operating system) runs in the foreground and the digital cluster running in the background is displayed even though it is its own display. However, there are limitations in displaying information. In addition, there is a problem that multimedia playback and navigation that were output through the digital cluster are not displayed, making it impossible to use convenient information.

Losing the unique functions of a digital cluster just to share its display may require improvement.

Ultimately, the vehicle cluster, including the digital cluster, requires the need to control the display screen configuration of the vehicle cluster for safe operation of the vehicle when executing smartphone functions through connection to a smartphone.

At this time, the smartphone screen may be displayed at a size set in consideration of the resolution of the smartphone 2.

When an event signal including vehicle status information, safety information, convenience information, and app information is generated, the type of the event signal is checked (S22), and the display screen configuration for the event signal is determined by referring to the mapping table (S23). .

Accordingly, the display screen configuration corresponding to the event signal is configured in the determined manner (S24). For example, if the event signal is an important signal related to safety, the corresponding safety information can be displayed on the entire screen of the display 16 of the vehicle cluster 1. Alternatively, when the screen is divided at a certain ratio and related information is displayed in the corresponding area, important information generated in each area can be displayed by overlaying the corresponding area.

This process can be equally applied when an event signal is generated from the smartphone 2. At this time, the event signal can be limited to what is displayed in the area where the smartphone screen is displayed.

Figure 7 is a flowchart showing a method of configuring a display screen of a vehicle cluster during screen mirroring, as an embodiment of the present invention.

If the control channel is available on the smartphone 2, the vehicle cluster 1 can receive a message about it from the smartphone 2. At this time, the control channel is a channel through which the smartphone 2 can control the vehicle cluster 1, and can be UIBC when the vehicle cluster 1 and the smartphone 2 use Miracast communication. The vehicle cluster 1 can receive identification information of the smartphone 2 when connected to the smartphone 2 through screen mirroring.

When the screen mirroring connection is established, the vehicle cluster 1 obtains screen resolution information from the smartphone 2 and determines the initial display position and size (S32).

Accordingly, the smartphone screen is displayed at a determined size in a specific area of the display 16 of the vehicle cluster 1 (S33). At this time, the smartphone screen displayed in a specific area of the display 16 of the vehicle cluster 1 can be configured as a display screen by adjusting the screen size so that it can be displayed in full screen in that area. In this way, the operating system of the vehicle cluster 1 and the operating system of the smartphone 2 are executed in the foreground state.

Thereafter, in response to touching the smartphone screen on the vehicle cluster 1, the vehicle cluster 1 may run the smartphone screen in the foreground state for a set time and run the vehicle cluster screen in the background state (S34 ).

If the user executes a specific app on the smartphone screen within the set time, the app type information of the specific app is obtained and the display screen configuration of the vehicle cluster 1 is determined (S35). If the user does not run a specific app on the smartphone screen within the set time, it returns to S33 described above.

Afterwards, when an event signal including vehicle status information, safety information, convenience information, and app information is generated, the type of the event signal is checked, and the display screen configuration for the event signal is determined by referring to the mapping table (S36).

In this way, even if a specific app is executed, the vehicle cluster 1 can change the foreground and background states at any time under the leadership of the operating system of the vehicle cluster 1 in response to an event signal (S37).

Figure 8 is a flowchart showing a mutual control process between a vehicle cluster and a smartphone as an embodiment of the present invention.

Referring to FIG. 8, when an input signal is generated in the vehicle cluster 1 while a specific app is running, the coordinate value is transmitted to the smartphone 2 through the coordinate application (S41).

Accordingly, the smartphone 2 can perform a function corresponding to the location (S42).

Afterwards, the execution process screen on the smartphone 2 is transferred to the vehicle cluster 1 (S43). At this time, not only can the display screen configuration be changed, but the display 16 of the vehicle cluster 1 and the smartphone The screen displayed on the display in (2) can be controlled differently (S44). That is, while the smartphone 2 progresses through the application's own execution process, the vehicle cluster 1 may output an image that is different from the smartphone 2's unique execution process. In other words, the vehicle cluster 1 and the smartphone 2 can display different images depending on the event signal generated in real time.

Similarly, when an input signal is generated in the smartphone 2, the coordinate value can be transmitted to the vehicle cluster 1 through a coordinate application.

Accordingly, the vehicle cluster 1 can perform a function corresponding to the location.
