Description
Technical Field
The invention relates to an automobile instrument and central control interaction system and method, in particular to a system and method for controlling navigation information by mutual transmission information of an automobile instrument and central control.
Background
Currently, a central control screen in an automobile has become an important point for the intelligent development of the control of the whole automobile. Many functions in automobiles have been changed from mechanical to electronic in coordination with the computation and detection of a drive computer and numerous sensors. Conventional center screens integrate numerous functions such as media control, navigation system display, control of automotive electronics, display and prediction of reverse images, and the like. Because the central control screen and the driving computer are mutually communicated, the central control screen is higher and higher in the automobile. Particularly in the field of driving assistance and internet automobiles, a center screen and center control have been indispensable parts.
However, the use of an automobile meter as a detecting component for driving state has been an important link for monitoring the interaction between the automobile and the user. The user does not use the central control screen to have great influence on the running of the automobile, but is necessary for the use and understanding of the instrument. Many data of the meter directly or indirectly have an influence on the driving safety. Such data are critical, like speed of travel, speed of rotation, turn signal, amount of oil, etc. In addition, many alarm messages are first displayed and reminded on the meter.
With the improvement of the status of the central control screen and the integration of control functions, the center of gravity on intelligent control is shifted towards the central control screen. Moreover, because the center control is usually designed separately from the meter and is also installed at the front row separately, the user can easily deflect the line of sight to the center control screen. Various information on the central control screen is very attractive, and has a certain risk for driving safety. There have also been some developments to incorporate a central control screen with the meter. There are a number of problems to be solved in the art. In the general solution, the instrument is used as the device for outputting and displaying, and the control and calculation of the driving computer are not participated, or the data of the instrument is used as the parameter of central control.
In general, a designer specifies a communication scheme for a specific scenario and a specific action. That is, the actions of the two interacting parties are not consistent in different scenarios. In particular, for certain information data, a designer specifies a particular timing sequence, and for a control system, a wide variety of procedures are to be maintained. Such interactions are often prone to error and are also very stressed on the control system. In particular for navigational information, navigational information in the meter generally follows only the setting of the central control, with no autonomous action. Many of the travel state information and navigation information in the meter are closely related.
However, it is quite desirable for the meter to be the most basic and direct control device how to maximize the data and functions of the meter. The data of the control center and the data of the instrument are organically combined, so that the control calculation of the control center and the calculation of the instrument are effective ways for playing the roles of the two.

The meter module 20 and the control module 10 communicate an interaction message 40 to each other via the data channel 30. With the interaction information 40, the control module 10 and the meter module 20 may perform data transmission, and the control module 10 and the meter module 20 perform the execution of the action according to the interaction information 40, respectively.
The control module 10 can send and receive data information, and the control module 10 is connected with the controlled automobile electronic equipment to send control information. Preferably, the control module 10 is preferably an automotive central control device, and is connected to the electronics of the automobile so as to control the electronics in the automobile. For example, the control module 10 is preferably a central control device, and the control module 10 may control information displayed in a central control screen. In addition, the control module 10 is preferably a front-end infotainment control module (FICM), and the control module 10 is connected to an electronic entertainment device in a car and controls playing of entertainment information.
The meter module 20 can receive and transmit data information and display the information via a dashboard. The dashboard is communicatively coupled to the meter module 20 to demonstrate actions performed by the meter module 20. In addition, the meter module 20 may be inputted with instructions, and preferably, the meter module 20 is inputted with instruction information through a control input device. It should be noted that the meter module 20 may be controlled by the control module 10, and communicate with the control module 10 via the data channel 30. The meter module 20 may also be directly input with control information by the square input device. The control module 10 may receive information of the square control input device through the data channel 30. In the preferred embodiment, the square control input device is preferably implemented from input devices such as a meter steering wheel key, a meter steering wheel touch screen, a meter steering wheel gesture recognition device and the like.
In the system and method for interaction between an automobile instrument and a central control provided by the invention, the instrument module 20 and the control module 10 both have a judging mechanism, that is, whether the instrument module 20 is to interact with the control module 10 or not can be determined by the instrument module 20. In contrast, whether the control module 10 performs an action according to the interaction information 40 is also determined. The data channel 30 through which the meter module 20 and the control module 10 interact is also provided while maintaining the independence of the meter module 20 and the control module 10, making the interaction of the meter module 20 and the control module 10 more flexible. In the preferred embodiment, the meter module 20 is not only an output actuator of the control system, but the meter module 20 has the capability of judging whether to execute or not the interaction information 40 sent by the control module 10. The interaction information 40 further includes a navigation status signal 41, an action request 42, and a navigation status information 43, wherein the navigation status signal 41 is a data signal for mutually confirming the status of the control module 10 and the meter module 20, the action request 42 is information for mutually transmitting the request action between the control module 10 and the meter module 20, and the navigation status information 43 is status data for mutually transmitting the control module 10 and the meter module 20. The content of the navigation status signal 41, the action request 42 and the navigation status information 43 may be edited and updated for communication between the control module 10 and the meter module 20.
An overall schematic of the preferred embodiment is shown in fig. 1. The control module 10 and the meter module 20 communicate with each other via the data channel 30. Preferably, the data channel 30 is a CAN bus network, and may connect the control module 10 and the meter 20, and also connect communications of other electronic devices in the automobile, such as ECU, LDW, and so on. In addition, the data channel 30 preferably uses an LVDS data interface, and the data channel 30 has higher efficiency for the image information transmitted from the control module 10 to the meter module 20 by using LVDS.
Further, the flow of interaction of the control module 10 with the meter module 20 is as shown in fig. 2. First, the control module 10 determines whether it is in a navigation state. For the control module 10 in a navigational state, the meter module 20 will receive the relevant navigational state signal 41 to confirm the navigational state of the control module 10. The meter module 20 determines whether to switch the navigation image based on the navigation status signal 41. The meter module 20 determines whether to switch or not based on the environmental data at the time of analysis. If it is determined that the navigation image is to be switched, the meter module 20 will perform a corresponding action. If it is determined that the navigation image is not to be switched, the meter module 20 decides not to perform the corresponding action. The meter module 10 feeds back the execution result, and the control module 20 grasps the execution result of the meter module 10. It should be noted that the interaction information 40 is related data of navigation information.
More specifically, in the preferred embodiment, the flow of the navigation status signal 41 at the time of the interaction initiated by the control module 10 is shown in fig. 3. The control module 10 sends the navigational status signal 41 to the meter module 20. The meter module accepts the navigation status signal 41, and the meter module 20 determines the validity of the navigation status signal 41. Upon determining the navigational state signal 41, the meter module 20 analyzes the navigational state signal 41. It is determined whether the navigation status signal 41 is valid for the meter module 20. For the active case, the meter module 20 performs the corresponding active case action in accordance with the navigational status signal 41. Correspondingly, for the case of invalidation, the meter module 20 executes a corresponding action in the case of invalidation in accordance with the navigation status signal 41. After performing an action, the meter module 20 feeds back to the control module 10, and the processing of the navigation status signal 41 is also fed back. The meter module 20 will wait for the next interactive communication of the control module 10.
The flow chart of the control module 10 of the preferred embodiment issuing the action request 42 to the meter module 20 is shown in fig. 4. First, the control module 10 issues the action request 42 to the meter module 20. The meter module 20 receives the action request 42. The meter module 20 then makes a determination as to whether the action request 42 is to be performed. If the meter module 20 determines that the action request 42 is to be performed, the meter module 20 will perform the relevant action in accordance with the action request 42. The meter module 20 broadcasts all-in-one status information 41 regarding the updated action request 42. After receiving the status information 41 broadcast by the meter module 20, the control module 10 confirms that the action request 42 is completed, cancels the action request 42, and completes the action request 42 sent by the control module 10 to the meter module 20. If the meter module 20 determines that the action request 42 is not to be performed, then the meter module 20 does not perform the relevant action. The meter module 20 broadcasts the status information 41 regarding the action request 42 as a full vehicle. After receiving the status information 41 broadcast by the meter module 20, the control module 10 confirms that the action request 42 is refused to be executed for further processing.
As shown in fig. 5, the image navigation status signal 41 is preferably in a state where the control module 10 is image-ready, and if the image navigation status signal 41 is TRUE, the control module 10 is ready for image. Preferably, the image navigation status information 43 is image data transmitted from the control module 20 to the meter module 10, so that the meter module 10 is controlled to display a corresponding image.
Specifically, the control module 10 sends the image navigation status signal 41 to the meter module 20. The meter module 20 receives the image navigation status signal 41 and determines the image navigation status signal 41. When the image navigation status signal 41 is determined to be valid, the meter module 20 knows that the control module 10 is ready to transmit the image navigation status information 43. The control module 10 sends out the image navigation status information 43 and the meter module 20 receives the image navigation status information 43. The meter module 20 determines whether to execute the content of the image navigation status information 43 according to the judgment of the image navigation status signal 41. If it is determined to perform the image navigation status information 43, the meter module 20 adjusts the image output to the dashboard. The meter module 20 updates the image navigation status signal 41 to inform the control module 10 that execution of the image status signal 43 has been completed. The control module 10 receives the image navigation status signal 41 and obtains feedback to wait for the next interaction. If the image navigation status signal 41 is judged to be invalid, the meter module 20 ignores the image navigation status information 43 issued by the control module 10. The image navigation status signal 41 is not changed and updated and the control module 10 gets feedback knowing that the meter module 20 refuses to execute waiting for further processing.
The above preferred embodiment of the present invention is shown in fig. 6, where the meter module 20 is required to switch images, the meter module 20 needs to interact with the control module 10 to obtain the corresponding image navigation status information 43. In a possible preferred case, the meter module 20 is switched by the direct input image of the square control input device, and the meter module 20 and the control module 10 are required to interact, the flow of which is similar to that of fig. 5 of the previous embodiment. Preferably, the image navigation status information 43 is image data transmitted from the control module 20 to the meter module 10, so that the meter module 10 is controlled to display a corresponding image. Preferably, the image navigation status signal 412 is a status of image switching of the meter module 20, and if the image navigation status signal 412 is TRUE, the meter module 20 has switched images.
Specifically, the meter module 20 sends the switch navigation status signal 411 to the control module 10 requesting the control module 10 to provide the corresponding information of the switch image. In the preferred embodiment, the switching image provided by the control module 10 is preferably a switching image between map navigation, multimedia, communication, voice recognition, etc. The control module 10 receives the switch navigation status signal 411 and prepares the corresponding image navigation status information 43 to the meter module 20. The meter module 20 makes a determination as to the priority of the switch navigation status signal 411. If the priority is high, the image navigation status information 43 is directly executed without the response of the control module 10. After execution, the meter module 20 updates the image navigation status signal 412 and informs of the feedback performed by the control module 10. If the control module 10 is required to answer, the image information in the data channel 30 is switched. After the meter module 20 has completed execution, the image navigation status signal 412 is updated and feedback is notified to the control module 10.
The above preferred embodiment of the present invention is shown in fig. 7, wherein the control module 10 is required to modify the navigation information of the instrument panel through the meter module 20. The action request 42 is an action requesting modification of navigation information, the navigation status information 43 is navigation information provided by the meter module 20, and the navigation status signal 41 is an execution status signal of the meter module 20 for modification of navigation information.
Specifically, the control module 10 receives a request for setting external navigation information, and the control module 10 issues the action request 42 to the meter module 20. The meter module 20 receives the action request 42 and the meter module 20 determines whether the action request 42 is to be performed. After execution of the meter module 20, the dashboard will update the navigation information, and the meter module 20 will edit the navigation status information 43 and update. The meter module 20 broadcasts the new navigation status information 43. After the control module 10 obtains the new navigation status information 43, the execution status of the meter module 20 is updated and the action request 42 is cancelled. If the meter module 20 determines that the action request 42 is not to be performed, the meter module 20 broadcasts the corresponding navigation status signal 41 informing the control module 10 of the refusal to perform the action request 42. Preferably, the meter module 20 has additional navigational information adjustment settings that cannot be altered by external settings, and the meter module 20 will determine not to execute the action request 42. The control module 10 marks the setting of the current navigation information as failed. The control module 10 cancels the action request 42 in accordance with the navigational status signal 41 rejected. Thus, both the meter module 20 and the control module 10 have a decision mechanism, and whether the meter module 20 is to interact with the control module 10 can be determined by the meter module 20. In contrast, whether the control module 10 performs an action according to the interaction information 40 is also determined. The data channel 30 through which the meter module 20 and the control module 10 interact is also provided while maintaining the independence of the meter module 20 and the control module 10, making the interaction of the meter module 20 and the control module 10 more flexible.
