And the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Fig. 1 is a schematic structural diagram of a system for interaction between a vehicle and the outside, according to an embodiment of the present application, and as shown in fig. 1, the system includes: control command input device 110, communication module 120, control module 130, and interactive signal presentation apparatus 140.
The control instruction input device 110 is configured to respond to a control instruction input by a user and transmit the control instruction to the communication module 120.
The communication module 120 is configured to transmit the control instruction to the control module 130.
The control module 130 is configured to perform processing according to the control instruction to obtain and send an interactive signal corresponding to the control instruction to the interactive signal presentation device 140; the interactive signals comprise interactive signals of at least two display modes;
the interactive signal display device 140 is used for displaying the interactive signals of at least two display modes to the outside.
As for the control instruction input device 110, in a specific implementation, a user inputs a control instruction on the control instruction input device 110 during driving of the vehicle, and the control instruction input device 110 transmits the control instruction to the communication module 120 in response to the control instruction input by the user. The control command is a signal for instructing the control module 130 of the vehicle to control the interactive signal presentation device 140 of the vehicle. The control commands may include not only traffic signals, such as "brake signal", "turn signal" and "reverse signal", but also other interactive signals, such as "child in car", "passing lane", "danger encountered ahead" and "hi to other vehicles", etc.
Typically, the control command input device 110 includes a mobile terminal, an instrument center console, and/or a vehicle driving system.
As an example, the control instruction input device 110 includes a mobile terminal. As a more specific example, the mobile terminal may be a mobile phone, an iPad, or other terminal device.
The mobile terminal is provided with an application client side for interaction between the vehicle and the outside. A plurality of function display modules corresponding to different states of the vehicle are arranged in a display area of an application client side on the mobile terminal, wherein the vehicle interacts with the outside, and a user can trigger a control instruction corresponding to the function display module by clicking the function display module on the application client side to be used as a control instruction input by the user; the application client responds to the control instruction input by the user, and the application server corresponding to the application client of the mobile terminal transmits the control instruction to the communication module 120.
As another example, the control command input device 110 includes an instrument center console.
Wherein, the instrument center console is located inside the vehicle, is provided with the display screen on the instrument center console, and the integrated control interface that has can respond to user input control command on the display screen, as shown in fig. 2, the example picture of the display screen on this instrument center console includes: a control interface of "child in the vehicle", "passing lane change", a control interface of "danger encountered ahead", a control interface of "hi'" for another vehicle ", and the like.
A user can trigger a control instruction corresponding to a control interface by clicking the corresponding control interface on a display screen of the instrument center console to serve as the control instruction input by the user; the meter console responds to control commands entered by the user and the control commands are transmitted by the meter console to the communication module 120.
As still another example, the control instruction input device 110 includes a vehicle driving system.
The vehicle driving system is positioned in a vehicle and is used for controlling the running state of the vehicle according to the operation of an accelerator, a brake, a steering and the like of the vehicle. The vehicle driving system includes: and control commands such as 'vehicle start running' and 'backing up'.
A user can generate a control instruction corresponding to a control component by triggering the corresponding control component of the vehicle driving system, and the control instruction is used as a control instruction input by the user; the vehicle driving system responds to control commands input by the user and the control commands are transmitted by the vehicle driving system to the communication module 120.
As still another example, in order to achieve the effect of interaction between the vehicle and the outside as much as possible and improve the driving experience of the user, the control instruction input device 110 may include a mobile terminal, an instrument console, and a vehicle driving system at the same time.
The user can click a function display module on a corresponding application client on the mobile terminal and click a corresponding control interface on a display screen of the instrument center console by triggering a corresponding control component of the vehicle driving system; the vehicle driving system generates a corresponding control instruction according to the triggered control component, and simultaneously generates a corresponding control instruction according to a clicked function display module of a corresponding application client on the mobile terminal, and the instrument center console generates a corresponding control instruction according to a clicked control interface; the control commands are responded to by the vehicle's driving system and instrument center console and transmitted to the communication module 120.
The communication module 120 refers to a module that can implement a data interaction function between the control instruction input device 110 and the control module 130. During specific implementation, the communication module 120 may be at least one of a vehicle body control module, a bluetooth module, a CAN bus, or a WIFI module.
As one implementation, the communication module 120 may receive the control instruction output by the control instruction input device 110 and transmit the received control instruction to the control module 130. That is, the control instruction output by the control instruction input device 110 is transmitted to the control module 130 through at least one of the vehicle body control module, the bluetooth module, the CAN bus, and the WIFI module.
It is to be understood that when the control instruction input device 110 includes a mobile terminal, the communication module 120 may be a WIFI module in one case. The vehicle on the mobile terminal of the user interacts with the external application client through the WIFI module and the control module 130. A WIFI module is integrated on the control module 130 or the interactive signal display device 140, and the application client of the vehicle interacting with the outside on the mobile terminal can search the IP address of the WIFI module and log in, so that the application client of the vehicle interacting with the outside on the mobile terminal can directly send a control instruction to the control module 130, so that the control module 130 can realize subsequent control.
Alternatively, the communication module 120 may be a CAN bus. An application client of a vehicle on a mobile terminal of a user interacting with the outside interacts with the control module 130 through a vehicle-mounted T-BOX (telematics BOX) and a CAN bus, wherein the vehicle-mounted T-BOX is a component in a vehicle networking system. It should be noted that, when a user needs to control a vehicle through an application client on the mobile terminal where the vehicle interacts with the outside, the user needs to perform identity authentication on the mobile terminal and the vehicle-mounted T-BOX, and after the identity authentication is successful, the user CAN complete transmission of a control instruction through the vehicle-mounted T-BOX and the CAN bus. Specifically, after the user sends a control command through the application client on the mobile terminal where the vehicle interacts with the outside, the vehicle-mounted T-BOX receives the control command and sends the control command to the control module 130 of the vehicle through the CAN bus, so that the control module 130 realizes subsequent control.
After receiving the control command, the control module 130 may obtain an interactive signal corresponding to the control command by processing the control command. The interactive signal comprises interactive signals of at least two display modes. As an example, the control module 130 may include control software and control circuitry, wherein the control software is capable of processing control instructions into an interactive signal that the control circuitry is capable of recognizing, and then the control circuitry is capable of controlling the presentation of the interactive signal.
In some implementations, a database is preset and stored in the control module 130, and the database stores the corresponding relationship between the control command and the interactive signal. The control module 130 may search a corresponding relationship including the control instruction from a preset database according to the control instruction, and obtain an interaction signal in the corresponding relationship, as the interaction signal corresponding to the control instruction obtained by the control module 130.
The interactive signals are signals which are displayed to the outside to enable the outside to know the internal condition of the vehicle and the running state of the vehicle, and each interactive signal represents the indication information of the corresponding control command. The interactive signal may specifically be an interactive signal pre-stored in a storage unit of the control module 130, and the user may update the interactive signal pre-stored in the storage unit through a storage device accessible to the USB port or a network; the interactive signal may also be an interactive signal downloaded by the control module 130 in real time through a network, and the user may download the interactive signal in real time through an application client or an instrument console on the mobile terminal where the vehicle interacts with the outside.
As an example, a storage unit of the control module 130 stores a corresponding relationship between the control instruction and the interactive signal in advance, and after the control module 130 receives the control instruction, the control instruction needs to be searched in the storage unit, and the interactive signal corresponding to the control instruction is determined according to the corresponding relationship between the control instruction and the interactive signal.
As another example, after receiving the control instruction, the control module 130 needs to download an interaction signal through an application client of the mobile terminal connected to the vehicle, where the vehicle interacts with the outside, and feed the interaction signal back to the control module 130 through the communication module 120, or may download the interaction signal through an instrument console of the vehicle and send the interaction signal to the control module 130. Then, the control module 130 determines the received interactive command as an interactive signal corresponding to the control command.
As another example, for the richness of the subsequent interactive signals, it is also necessary to be able to download the updated interactive signals at any time, and then the communication module 120 may also be an ethernet network. In a specific implementation, the user may download the interactive signal through an application client or an instrument console of the mobile terminal where the vehicle interacts with the outside at any time, and transmit the interactive signal to the interactive signal display device 140 through the ethernet. The transmission of the interactive signals is carried out through the Ethernet, so that the effects of rich transmission content, more various and timely transmission information and the like can be realized.
The control module 130 sends the obtained interactive signal to the interactive signal presentation device 140, and the interactive signal presentation device 140 presents the interactive signal obtained by the control module 130 to the outside, that is, the interactive signal of at least two presentation modes. Specifically, there are several display modes of the interactive signal, which are related to the interactive signal display device 140 on the vehicle.
In the present embodiment, the interactive signal presentation apparatus 140 may include a display apparatus 141 and a vehicle lighting apparatus 142 mounted on a vehicle body; the interactive signals of the at least two presentation modes may include a signal displayed through the display device 141 and a car light signal presented through a car light lighting mode. A display device 141 for displaying and playing the signal displayed and played by the display device 141; and a vehicle lighting device 142 for displaying a lamp signal displayed by a lamp lighting manner.
It should be noted that, in the embodiment of the present application, the signal sources for displaying the broadcast through the display device 141 may be the following two types: pre-storing and downloading in real time. When the signal is derived from the pre-stored mode, the signal may be pre-stored in the first control sub-module 131 and may be updated through a USB interface or the like. When the real-time downloading is available, the signals can be downloaded through the mobile terminal or the instrument console in a networking mode in time.
When the signal displayed by the display device 141 is pre-stored in the first control sub-module 131, the communication module 120 may be a CAN bus, because the signal displayed by the display device 141 is not required to be transmitted through the communication module 120.
When the display device 141 displays the played signal and needs to download the signal in real time, the communication module 120 may be a WIFI module, and the signal is downloaded and updated at any time through the ethernet by implementing networking through the WIFI module. Under the example, the user can download the video through the mobile terminal or the instrument console at any time, and can download the video from the network at any time through Ethernet transmission, the transmitted content is greatly enriched, and the transmitted information is more diversified and timely.
In a specific implementation, the vehicle lighting device 142 refers to a lamp outside the vehicle, and may include 4 groups of lamps, and 2 groups of lamps in front and rear of the vehicle. Each group of car lamps can be a single headlight or a group of series-connected small car lamps. If each group of car lamps comprises a group of car lamps connected in series, the lighting sequence of the car lamps can be controlled, and then the vehicle lighting device 142 is controlled to transmit the external signals, so that different interaction modes with the outside are realized.
It should be noted that, in the embodiment of the present application, the Light source used by the vehicle lighting device 142 may be a conventional LED Light source, and may also be a PM OLED (Passive Matrix Organic Light Emitting Diode) or an AMOLED (Active Matrix Organic Light Emitting Diode) display panel Light source. The PM OLED has the characteristics of high brightness, bright color and three-dimensional space, different letters can be dynamically lightened and displayed in different areas of a single chip, and multiple chips can also be dynamically lightened. The AM OLED has the characteristics of high-precision display and clear display of different information. The PM OLED display screen and the AM OLED display screen can bring brand new interactive experience to users.
The display device 141 may be a device for displaying a playing signal, such as a display screen, and is configured to play a part of the interactive signal sent by the control module 130, and specifically, the played interactive signal may include an image signal, a video signal, and/or a text signal. The display device 141 may be mounted at any position of the vehicle body. For example, as shown in fig. 3, the display device 141 may transmit signals to the outside according to the state that two sets of tail lights of the vehicle and one display device 141 cooperate with each other.
As an example, in order to make the outside world understand the condition of the vehicle more and realize multi-directional interaction between the vehicle and the outside world, the number of the display devices 141 may be multiple, and the multiple display devices 141 are respectively installed on different directions of the vehicle body. For example, the vehicle may include three display devices 141 respectively installed between two sets of tail lamps of the vehicle body, two sets of head lamps of the vehicle body, and the roof of the vehicle body.
When the interactive signal display device 140 comprises the display device 141 and the vehicle lighting device 142, the expression, the text and the picture video which need to be interacted can be displayed in a high-definition manner, and real-time high-quality interaction of fine information is realized. In one case, the display device 141 and the vehicle lighting device 142 may be connected together through a serial interface, and the fine video information displayed by the display device 141 and the dynamic lighting of the vehicle lighting device 142 are linked to form an organic whole communication effect, so as to express information to be communicated more clearly, and through the cooperation of the display device 141 and the vehicle lighting device, an interactive signal is more vividly displayed to the outside.
In a specific implementation, the control module 130 may search an interaction signal corresponding to the control instruction from a preset database according to the control instruction; the obtained interactive signal corresponding to the control command may be transmitted to the display device 141 and/or the vehicle lighting device 142 in the interactive signal presentation device 140.
As an example, if the display device 141 receives the interaction signal transmitted by the control module 130, in some examples, the display device 141 may transmit the interaction signal to the vehicle lighting device 142 through a serial interface, and then the display device 141 displays the played signal through the display device 141 in playing the interaction signal, and the vehicle lighting device 142 displays a vehicle light signal displayed by a vehicle light-on manner in the interaction signal. Alternatively, in some examples, the display device 141 may further transmit the interactive signal of the car light signal displayed by the car light lighting manner in the interactive signal through the serial interface to the vehicle lighting device 142, and then the display device 141 displays the played signal displayed by the display device 141 in the interactive signal, and the vehicle lighting device 142 displays the received car light signal displayed by the car light lighting manner.
As another example, the vehicle lighting device 142 may receive the interaction signal sent by the control module 130, and after receiving the interaction signal, the operation performed by the vehicle lighting device 142 may refer to the operation performed by "the display device 141 receives the interaction signal", which is not described herein again.
As another example, the control module 130 may also send the obtained interaction signal corresponding to the control command to the display device 141 and the vehicle lighting device 142 in the interaction signal presentation device 140 at the same time, and both of them may achieve the effect of presenting the interaction signal to the outside without transmitting the interaction signal through a serial interface. However, the display device 141 and the vehicle lighting device 142 can still be matched through the serial interface between the two devices, so that the displayed interactive interface is clearer and smoother, and the user experience is improved.
Alternatively, the display device 141 and the vehicle lighting device 142 may be independent from each other. That is, the display device 141 and the vehicle lighting device 142 are not in communication with each other, and data interaction is not possible.
In this case, the control module 130 specifically includes: the first control submodule 131 and the second control submodule 132, wherein the first control submodule 131 is configured to search a preset database according to a control instruction and send a signal corresponding to the control instruction and displayed and played by the display device 141 to the display device 141; the second control sub-module 132 is configured to obtain and send a vehicle light signal, which is displayed in a vehicle light-on manner and corresponds to the control instruction, to the vehicle lighting device 142 according to the control instruction.
In some examples, after the control module 130 receives the control instruction, the first control sub-module 131 in the control module 130 searches a preset database for a signal corresponding to the control instruction and displayed and played by the display device 141 according to the control instruction, and the first control sub-module 131 sends the signal displayed and played by the display device 141 to the display device 141, and then the display device 141 displays and plays the signal displayed and played by the display device 141; the second control sub-module 132 in the control module 130 obtains the car light signal displayed in the car light lighting mode corresponding to the control instruction according to the control instruction, and the second control sub-module 132 sends the car light signal displayed in the car light lighting mode to the vehicle lighting device 142, and then the vehicle lighting device 142 displays the car light signal displayed in the car light lighting mode.
It should be noted that, when the interactive signal display device 140 includes the display device 141 and the vehicle lighting device 142, the system for vehicle interaction with the outside provided in the embodiment of the present application can also achieve a dynamic lighting effect in which the vehicle lighting device 142 and the display device 141 are coordinated and unified. The specific implementation process can be as follows:
after the control instruction is input through the control instruction input device 110, the control instruction is transmitted to the first control sub-module 131 and the second control sub-module 132 through the communication module 120, wherein the first control sub-module 131 calls the pre-stored or real-time downloaded interactive signal video or picture and transmits the interactive signal video or picture to the display device control circuit, so that the display device 141 displays the corresponding content.
The second control sub-module 132 processes the control command and transmits the control command to the vehicle lamp control circuit to control the dynamic lighting of the light source array in the vehicle lamp.
Since the control instructions received by the first control sub-module 131 and the second control sub-module 132 are the same control instruction, the contents displayed by the display device 141 and the vehicle lighting device 142 can be matched with each other through related design, and a good dynamic display effect is achieved.
It can be understood that, on the display screen that sets up on the mobile terminal, through opening the vehicle and the interactive application client in the external world, also can with display screen and display device on the instrument console show the same interactive signal to the user can know the interactive condition of vehicle and external world in real time, avoids showing wrong interactive signal to the external world, has promoted user experience.

The control signal that the ethernet can transmit can be a video downloaded from the network at any time.
In this embodiment, it is realized that ethernet is used inside the vehicle to transmit the mobile terminal or the central control screen picture and the video big data to the display device 141 and the vehicle lighting device 142 of the vehicle at a high speed, so that the display content of the tail lamp and the display screen CAN be updated in real time, which cannot be realized by the conventional CAN-LIN control wire and the like.

As an optional embodiment of the application, in order to interact more detailed information to the outside, for example, display the encountered specific dangerous situation, the specific brake type and the like to the outside. The embodiment of the application also provides another implementation mode of the system for the interaction between the vehicle and the outside.

The vehicle speed obtaining module 850 is used for responding to a braking instruction input by a user and obtaining the deceleration of the vehicle;
a brake type analysis module 860 for determining a current brake type according to a deceleration of the vehicle;
the control instruction input device 810 has the same function and structure as the control instruction input device 110 described above, and will not be described in detail here.
The communication module 820 is used for transmitting the information of the current brake type to the control module 830 in addition to the functions of the communication module 120;
the interactive signal presentation apparatus 840 may have, in addition to the functions of the interactive signal presentation apparatus 140 described above, functions in which,
the display device is also used for displaying a brake signal corresponding to the current brake type;
the vehicle lighting device is also used for displaying a brake signal corresponding to the current brake type.
As an optional implementation manner of the present application, the vehicle speed obtaining module 850 may specifically include:
the first acquisition unit is used for responding to a braking instruction input by a user and acquiring vehicle speed information;
a first calculation unit for calculating a deceleration of the vehicle based on the vehicle speed information.
As another alternative implementation of the present application, the vehicle speed obtaining module 850 may specifically include:
the second acquisition unit is used for responding to a braking instruction input by a user and acquiring a position signal of a brake pedal;
a second calculation unit for calculating the deceleration of the vehicle based on the position signal of the brake pedal.
In this alternative implementation, as an example, the position signal of the brake pedal may be a percentage of the actual travel of the brake pedal over its total travel. Thus, in this example, the position signal of the brake pedal may be specifically: when a driver steps on a brake pedal to brake a vehicle, the actual position of the brake pedal is detected through a brake pedal position sensor, the sensor transmits a voltage signal to a gateway, and the gateway performs amplification conversion and operation processing to send a pedal position signal. The pedal position value is output by conversion as a percentage of the total pedal travel.
As yet another alternative implementation of the present application, the vehicle speed acquisition module 850 may acquire the deceleration of the vehicle based on the vehicle speed and the position signal of the brake pedal to improve the accuracy of the calculated deceleration of the vehicle.
As another optional implementation manner of the present application, the brake type analyzing module 860 may specifically include:
comparing the deceleration of the vehicle with a first preset deceleration threshold value, and comparing the deceleration of the vehicle with a second preset deceleration threshold value; the first preset deceleration threshold is less than a second preset deceleration threshold;
when the deceleration of the vehicle is smaller than the first preset deceleration threshold value, determining that the current brake type is slow brake deceleration;
when the deceleration of the vehicle is between the first preset deceleration threshold and the second preset deceleration threshold, determining that the current braking type is normal braking;
and when the deceleration of the vehicle is greater than the second preset deceleration threshold value, determining that the current braking type is emergency braking.
In the embodiment of the application, the display device may be specifically configured to display at least one of a vehicle speed, a deceleration, a brake type, a warning identifier for warning a current dangerous condition, and voice information input by a user in a text, picture, and/or video manner; wherein, the voice information input by the user is displayed in the form of characters or pictures.
As an example, as shown in fig. 9, the display content of the display device may include:
1) and (3) brake type:
as an example of the present application, the braking type may include, according to the difference in deceleration of the vehicle: emergency braking, normal braking and slow braking deceleration.
The brake type can be displayed in a text form. In addition, the brake type can also be displayed in the form of a warning mark. In addition, the brake type is also displayed in a form of combining characters with warning marks.
2) Vehicle speed and vehicle acceleration.
3) And (4) warning identification:
as an example, the warning mark may be a warning mark for warning the current dangerous situation, such as a warning mark of "rock fall ahead" shown by an oval broken line frame in fig. 9.
In addition, the brake type may also be displayed by an alarm indicator, such as the alarm indicator shown by the rectangular dashed box in fig. 9. For example, pictures of different colors may be used to identify different brake types, e.g., emergency brakes are identified as falling off rapidly (e.g., 10 drops per second) with a red warning; the yellow warning mark is adopted to fall at a constant speed (for example, 5 times per second) in normal braking; slow brakes fall slowly (e.g., twice per second) with a green warning sign.
4) Voice information input by a user or character information input through a central control screen:
by way of example, voice information entered by the user or text information entered through the center screen may describe a currently encountered situation, such as "rock fall ahead", "traffic accident ahead", "small animal ahead", and so forth.
Correspondingly, the vehicle lighting device can be used for flashing light according to different brake types and different rhythms. The lighting device may be a tail light for a vehicle. The display mode of the vehicle lighting device will be described below by taking the OLED tail light as an example. For example: during emergency braking, the flashing rhythm of the OLED tail lamp is that the water flows for 100ms, the light is on for 100ms, and the light is off for 200 ms; during normal braking, the flashing rhythm of the OLED tail lamp is 200ms flowing water, 200ms on and 400ms off, and during slow braking and deceleration, the flashing rhythm of the OLED tail lamp is 300ms flowing water, 300ms on and 300ms off.
In addition, when the vehicle is stationary, the display device and the vehicle lighting device can continue to display the related warning information in different brake types. For example:
after the emergency braking vehicle is stopped, the display screen continues to display related warning information, and the flashing rhythm of the OLED tail lamp is 200ms on 200ms off; after the vehicle is normally braked and is static, the OLED tail lamp does not flicker any more, and the display device displays a preset picture or user input information; after the slow brake is decelerated, the OLED tail lamp does not flicker any more, and the display device displays a preset picture or user input information; when the acceleration is larger than the set value, the vehicle is not considered to be decelerating, the vehicle is considered to be running normally, the OLED tail lamp does not flicker, and the display device displays a preset picture or user input information.
It should be noted that, in the system for interaction between a vehicle and the outside provided in the embodiment of the present application, the display device and the vehicle lighting device may work cooperatively, so as to achieve the purpose of displaying warning information to the outside at the same time, thereby providing more clear and precise warning information to the outside.
The foregoing is only a preferred embodiment of the present application and it should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
