These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. Depending on the context, moreover, the word "if" as used may be interpreted as "at … …" or "when … …" or "in response to a determination".

Referring to fig. 1A, a schematic structural diagram of a vehicle central control system, the vehicle central control system may include a processor and a central control display screen, and the central control display screen includes a display area a. The processor may acquire a service image, which may include but is not limited to navigation, entertainment, multimedia, and the like, and output the service image to the central control display screen, thereby displaying the service image to a user through the display area a of the central control display screen.

As the degree of vehicle intelligence increases, the center control display screen may support at least two display areas, for example, the center control display screen may include display area a1 and display area a 2. Referring to fig. 1B, in order to illustrate that the center control display screen includes two display areas, the display area a1 and the display area a2 may be divided up and down, and the display area a1 and the display area a2 may also be divided left and right, which is not limited thereto.

The processor may obtain control images, which may include business images and air conditioner interface images, which may be, without limitation, interfaces for controlling an air conditioner. The processor may output the control image to the center control display screen to display the service image to the user through the display area a1 of the center control display screen and the air conditioner interface image to the user through the display area a2 of the center control display screen.

For example, the vehicle center control system may include a genuine apparatus, and as shown in fig. 1A, the processor and the center control display screen belong to the genuine apparatus, that is, the control image may be acquired by the genuine apparatus and output.

With the continuous development of image technology, a plurality of cameras (such as a front view camera, a left view camera, a right view camera, a rear view camera, and the like) can be deployed on a vehicle, and in the running process of the vehicle, the cameras can acquire images around the vehicle, for example, the front view camera acquires an image in front of the vehicle (denoted as a front side image), the left view camera acquires an image on the left side of the vehicle (denoted as a left side image), the right view camera acquires an image on the right side of the vehicle (denoted as a right side image), the rear view camera acquires an image behind the vehicle (denoted as a rear side image), and outputs the images to a main controller, which may also be called a surround view controller.

The master controller, upon obtaining these images, may generate a aftermarket vehicle image based on these images, which may provide a user with a view of the surroundings of the vehicle, thereby providing visual assistance to the user's operation.

For example, the aftermarket vehicle image may also be referred to as a look-around image, which may include, but is not limited to: a panoramic overhead image and a panoramic monoscopic image. The panoramic overhead image may be generated from at least two images of the front image, the left image, the right image and the rear image, for example, a 360-degree panoramic overhead image is generated based on the above 4 images, or a left front panoramic overhead image is generated based on the front image and the left image, and the generation process of the panoramic overhead image is not limited.

The panoramic single-view image may be generated according to one of the front image, the left image, the right image and the rear image, for example, a panoramic single-view image of the front side of the vehicle may be generated based on the front image, and the panoramic single-view image of the front side of the vehicle may display the condition of the front side of the vehicle, so as to provide visual assistance for the operation of the user. For another example, a panoramic single-view image of the rear side of the vehicle can be generated based on the rear-side image, and the panoramic single-view image of the rear side of the vehicle can display the situation of the rear side of the vehicle.

In order to display the aftermarket vehicle image through the central control display screen, the vehicle central control system may include a processor, a central control display screen, a main controller and a switch. Referring to fig. 1C, a schematic diagram of a central control display screen including a display area a is shown. The processor acquires a service image, and the main controller acquires a rear-mounted vehicle image. When the service image needs to be displayed, the selector switch is connected with the processor, and the processor can output the service image to the central control display screen, so that the service image is displayed to a user through the display area a of the central control display screen. When the rear-mounted vehicle image needs to be displayed, the change-over switch is connected with the main controller, the main controller can output the rear-mounted vehicle image to the central control display screen, and the rear-mounted vehicle image is displayed to a user through the display area a of the central control display screen.

In addition to the original equipment (processor and central control display), the vehicle central control system further comprises aftermarket equipment, i.e. additional equipment is added on the basis of the existing original equipment, as shown in fig. 1C, and the main controller and the change-over switch belong to aftermarket equipment, i.e. aftermarket vehicle images are acquired through the aftermarket equipment and output. In summary, the original device is used to output the control image and the afterloader device is used to output the afterloader vehicle image.

Referring to fig. 1D, a schematic diagram of the center control display screen including a display area a1 and a display area a2 is shown. The processor acquires control images including service images and air conditioner interface images, and the main controller acquires afterloading vehicle images. When the control image needs to be displayed, the selector switch is connected with the processor, and the processor can output the control image to the central control display screen, so that the business image is displayed to the user through the display area a1 of the central control display screen, and the air conditioner interface image is displayed to the user through the display area a2 of the central control display screen. When the aftermarket vehicle image needs to be displayed, the changeover switch is connected to the main controller, and the main controller outputs the aftermarket vehicle image to the center control display screen, thereby displaying the aftermarket vehicle image to the user through the display area a1 of the center control display screen.

However, when the aftermarket vehicle image is displayed to the user through the display area a1, the display area a2 of the center control display screen is in a black screen state, resulting in poor visual effect for the user. The air conditioner interface image cannot be displayed for the user, so that the normal control of the air conditioner cannot be performed, and the normal use of the air conditioner by the user is influenced.

In view of the above findings, in the embodiment of the present application, the vehicle central control system may include an original device and an afterloading device, the original device may include a processor and a central control display screen, and the afterloading device may include a main controller and a logic chip, as shown in fig. 1E, a schematic structural diagram of the vehicle central control system is shown, and the structures of the processor, the central control display screen, the main controller and the logic chip are taken as examples to describe the functions of these devices, which will be described later.

The processor can acquire the control image, the control image comprises a business image and an air conditioner interface image, the control image is output to the logic chip, the main controller can acquire the afterloading vehicle image and output the afterloading vehicle image to the logic chip, and in conclusion, the logic chip can obtain the control image and the afterloading vehicle image.

When the control image needs to be displayed, the logic chip outputs the control image to the central control display screen, and the control image comprises a business image and an air conditioner interface image, so that the business image is displayed to a user through the display area a1 of the central control display screen, and the air conditioner interface image is displayed to the user through the display area a2 of the central control display screen.

When the aftermarket vehicle image needs to be displayed, the logic chip generates a fused image including the aftermarket vehicle image and the air-conditioning interface image in the control image from the control image and the aftermarket vehicle image, and outputs the fused image to the center control display screen, based on which the aftermarket vehicle image is displayed to the user through the display area a1 of the center control display screen, and the air-conditioning interface image is displayed to the user through the display area a2 of the center control display screen.

In summary, when the aftermarket vehicle image is displayed to the user through the display area a1, the display area a2 of the central control display screen displays the air conditioner interface image to the user, so that the display area a2 is prevented from being in a black screen state, and the visual effect of the user is improved. The air conditioner interface image can be displayed to the user, so that the air conditioner can be normally controlled.

The technical solutions of the embodiments of the present application are described below with reference to specific embodiments.

An embodiment of the present application provides an image display method, which is shown in fig. 2A and is a schematic flow chart of the image display method, and the method may be applied to a vehicle center control system, and the method may include:

at step 201, an image of the control and aftermarket vehicle images are acquired. Illustratively, the control image is an image output by an original equipment of the vehicle center control system (e.g., an image output by the processor in fig. 1E), and the aftermarket vehicle image is an image output by an aftermarket equipment of the vehicle center control system (e.g., an image output by the master controller in fig. 1E).

Step 202, generating a fused image according to the control image and the aftermarket vehicle image; the control image includes a first sub-image and a second sub-image, and the fused image includes the aftermarket vehicle image and the second sub-image.

In one possible embodiment, the control image may be split into a first sub-image and a second sub-image, and the aftermarket vehicle image and the second sub-image are combined into a fused image.

Assuming that the number of pixels of the control image is P, the number of pixels of the first sub-image in the control image is N, and the number of pixels of the second sub-image in the control image is M, the sum of M and N is P. The number of pixels of the aftermarket vehicle image is the same as the number of pixels of the first sub-image, i.e., the number of pixels of the aftermarket vehicle image is N.

The values of P, N, M are related to the actual resolution of the control image, and are not limited to this, for example, assuming that the resolution of the control image is 2880 × 720, the resolution of the first sub-image is 1540 × 720, the resolution of the second sub-image is 1340 × 720, and the resolution of the afterloading vehicle image is 1540 × 720, then P is 2880 × 720, N is 1540 × 720, and M is 1340 × 720. Of course, the above are examples of P, N, M only.

For example, the number of pixels N may be configured in advance, and after the control image and the aftermarket vehicle image are obtained, the control image may be divided into the first sub-image and the second sub-image based on the number of pixels N, for example, N pixels in front of the control image may be determined as the first sub-image, and the remaining pixels (i.e., M pixels) in the control image except the front N pixels may be determined as the second sub-image.

And combining the afterloading vehicle image with N pixels with the second sub-image with M pixels to obtain a fused image, wherein the number of pixels of the fused image is P. The N pixels in front of the fused image are the aftermarket vehicle image, and the remaining pixels (i.e., M pixels) in the fused image except the first N pixels are the second sub-image.

In another possible embodiment, the first sub-image in the control image may be replaced by the aftermarket vehicle image (i.e., the first sub-image is replaced by the aftermarket vehicle image), resulting in a fused image.

Assuming that the number of pixels of the control image is P, the number of pixels of the first sub-image in the control image is N, the number of pixels of the second sub-image in the control image is M, the number of pixels of the aftermarket vehicle image is N, and the sum of M and N is P, based on this, the number of pixels N may be configured in advance, after the control image and the aftermarket vehicle image are obtained, the N pixels in front of the control image may be replaced with the aftermarket vehicle image of N pixels, and the replaced control image is a fusion image, the N pixels in front of the fusion image may be the aftermarket vehicle image, and the remaining pixels in the fusion image except the N pixels in front may be the second sub-image.

And 203, outputting the fused image to a central control display screen, so that a rear-mounted vehicle image in the fused image is displayed through a first display area of the central control display screen, and a second sub-image in the fused image is displayed through a second display area of the central control display screen. The fused image comprises a rear-mounted vehicle image and a second sub-image, the central control display screen displays the rear-mounted vehicle image through the first display area, and the second sub-image is displayed through the second display area.

For example, assuming that the number of pixels of the fusion image is P, the number of pixels of the aftermarket vehicle image in the fusion image is N, and the number of pixels of the second sub-image in the fusion image is M, the sum of M and N is P.

After the central control display screen obtains the fused image, the central control display screen can display the N pixels in front of the fused image through the first display area, namely, display the rear vehicle image, and display the remaining pixels (namely, M pixels) in the fused image except the front N pixels through the second display area, namely, display the second sub-image.

Another image display method is provided in the embodiment of the present application, and as shown in fig. 2B, is a schematic flow chart of the image display method, and the method may be applied to a vehicle center control system, and the method may include:

and step 211, acquiring the display state of the central control display screen, wherein the display state indicates whether a rear-mounted vehicle image is displayed or not. For example, if the display status indicates that a rear-mount vehicle image is displayed, step 212 may be performed; if the display status indicates that no aftermarket vehicle images are displayed, step 215 may be performed.

In one possible implementation, the display state indicating information may be acquired, and the display state of the central control display screen may be acquired according to the display state indicating information. For example, if the display state indicating information is used to indicate a first display state, the display state of the center control display screen is the first display state, and the first display state indicates that the rear-mounted vehicle image is displayed. And if the display state indicating information is used for indicating a second display state, the display state of the central control display screen is the second display state, and the second display state represents that the rear-mounted vehicle image is not displayed.

For example, an in-vehicle control interface may be displayed to the user, information about a display state may be input by the user at the in-vehicle control interface, and display state indicating information may be acquired based on the information.

If the user needs to watch the rear-mounted vehicle image, information for displaying the rear-mounted vehicle image is input on the vehicle-mounted control interface, display state indicating information is obtained based on the information, and the display state indicating information is used for indicating a first display state, namely the display state of the central control display screen is obtained to show the rear-mounted vehicle image.

And if the user does not need to view the rear-mounted vehicle image, inputting information for not displaying the rear-mounted vehicle image on the vehicle-mounted control interface, and acquiring display state indicating information based on the information, wherein the display state indicating information is used for indicating a second display state, namely the acquired display state of the central control display screen indicates that the rear-mounted vehicle image is not displayed.

The vehicle-mounted control interface comprises a button for displaying the rear-mounted vehicle image, if the user clicks the button for displaying the rear-mounted vehicle image, the information for displaying the rear-mounted vehicle image is input in the vehicle-mounted control interface, and if the user clicks the button for not displaying the rear-mounted vehicle image, the information for not displaying the rear-mounted vehicle image is input in the vehicle-mounted control interface.

In another possible implementation, the operating state of the vehicle, which may include vehicle speed information (e.g., an actual vehicle speed of the vehicle, etc.) and/or vehicle steering information (e.g., left turn, right turn, reverse, etc.), may be obtained, and the display state of the central control display screen may be obtained according to the operating state. Illustratively, the vehicle is a vehicle provided with the vehicle central control system, namely, the original equipment and the after-loading equipment are arranged on the vehicle.

For example, if the vehicle speed information is less than the first speed threshold and the vehicle steering information is steering, the display state of the center control display screen is determined to be a first display state, and the first display state represents displaying the rear-mounted vehicle image. The first speed threshold may be configured empirically, such as 10 km/h, 15 km/h, and the like, without limitation, and when the vehicle speed information is less than the first speed threshold, it indicates that the vehicle is traveling at a low speed.

During low-speed running of the vehicle, the vehicle may perform operations such as turning left, turning right, backing up, etc., and therefore, if it is determined that the vehicle is turning based on the vehicle steering information, a rear-mount vehicle image is displayed to the user, and visual assistance is provided for the user's operation through the rear-mount vehicle image. If the vehicle steering information is left turn, the partial image of the left side position of the vehicle is displayed to the user, if the vehicle steering information is right turn, the partial image of the right side position of the vehicle is displayed to the user, and if the vehicle steering information is reverse, the partial image of the rear side position of the vehicle is displayed to the user.

For another example, if the vehicle speed information is greater than the second speed threshold and the vehicle steering information is steering, the display state of the center control display screen is determined to be a first display state, and the first display state indicates that a rear-mounted vehicle image is displayed. The second speed threshold may be configured empirically, such as 70 km/h, 80 km/h, etc., without limitation, and when the vehicle speed information is greater than the second speed threshold, it indicates that the vehicle is traveling at a high speed.

During high-speed running of the vehicle, the vehicle may make a lane change to the left, a lane change to the right, or the like, and therefore, if it is determined that the vehicle is turning based on the vehicle turning information, a rear-mount vehicle image may be displayed to the user. If the vehicle steering information is changing lane to the left, a partial image of the left position of the vehicle may be displayed to the user, and if the vehicle steering information is changing lane to the right, a partial image of the right position of the vehicle may be displayed to the user.

For another example, if the vehicle speed information is greater than the second speed threshold, the display state of the center control display screen is determined to indicate that the rear-mounted vehicle image is displayed regardless of the vehicle steering information (i.e., without paying attention to the vehicle steering information).

For example, if the vehicle steering information is not steering (i.e., no left turn, no right turn, no reverse, etc.) regardless of the vehicle speed information (i.e., no attention is paid to the vehicle speed information), the display state of the center control display screen may be determined to be the second display state, and the second display state indicates that no rear-mounted vehicle image is displayed.

For example, when the vehicle speed information is between the first speed threshold and the second speed threshold, the display state of the center control display screen is determined to indicate that the rear-mounted vehicle image is not displayed regardless of the vehicle steering information.

Of course, the above-mentioned display state obtaining manner is only a few examples, and is not limited thereto, as long as the display state of the central control display screen is related to the vehicle speed information and/or the vehicle steering information.

And step 212, acquiring a control image and a rear-mounted vehicle image, wherein the control image is an image output by original equipment of the vehicle central control system, and the rear-mounted vehicle image is an image output by rear-mounted equipment of the vehicle central control system.

Step 213, generating a fused image from the control image and the aftermarket vehicle image; the control image includes a first sub-image and a second sub-image, and the fused image includes the aftermarket vehicle image and the second sub-image.

And 214, outputting the fused image to a central control display screen, so that the afterloading vehicle image in the fused image is displayed through a first display area of the central control display screen, and a second sub-image in the fused image is displayed through a second display area of the central control display screen.

At step 215, an control image is acquired, the control image including a first sub-image and a second sub-image.

And step 216, outputting the control image to the central control display screen, so that a first sub-image in the control image is displayed through a first display area of the central control display screen, and a second sub-image in the control image is displayed through a second display area of the central control display screen.

For example, since the control image includes the first sub image and the second sub image, the center control display screen displays the first sub image through the first display area and displays the second sub image through the second display area.

For example, if the number of pixels of the control image is P, the number of pixels of the first sub-image in the control image is N, and the number of pixels of the second sub-image in the control image is M, the sum of M and N is P.

After the central control display screen obtains the control image, the central control display screen can display the N pixels in front of the control image through the first display area, namely, display the first sub-image, and display the rest pixels (namely, M pixels) except the front N pixels in the control image through the second display area, namely, display the second sub-image.

In fig. 2A or fig. 2B, the first sub-image may be a service image, which may include, but is not limited to, navigation, entertainment, multimedia, etc., without limitation, and the second sub-image may be an air conditioner interface image, which may be an interface for controlling an air conditioner, without limitation. Alternatively, the first sub-image may be an air conditioner interface image, and the second sub-image may be a service image. Of course, the service image and the air conditioner interface image are only examples, and the first sub-image and the second sub-image are not limited thereto.

In fig. 2A or 2B, the first display region is an upper side display region, and the second display region is a lower side display region; or the first display area is a lower display area, and the second display area is an upper display area; or the first display area is a left display area, and the second display area is a right display area; alternatively, the first display area is a right display area, and the second display area is a left display area.

In the above embodiment, two display areas are taken as an example, in practical applications, the central control display screen may include three or more display areas, and the number of the display areas is not limited. When the central control display screen comprises three or more display areas, the implementation mode is similar to that of the two display areas, and repeated description is omitted here. For example, in the case of three display areas, if the central control display screen receives the fused image, the aftermarket vehicle image in the fused image may be displayed together through the first display area and the second display area, and the second sub-image in the fused image may be displayed through the third display area. If the central control display screen receives the control image, the first sub-image in the fusion image can be displayed through the first display area and the second display area together, and the second sub-image in the fusion image can be displayed through the third display area.

The above process is described by taking the first sub-image as the service image, the second sub-image as the air conditioner interface image, the first display area as the upper display area, and the second display area as the lower display area as examples. Referring to fig. 2C, the logic chip obtains control images including business images and air conditioner interface images and aftermarket vehicle images. If the display state indicates that the rear-mounted vehicle image is not displayed, the logic chip outputs the control image to the central control display screen, and after the central control display screen obtains the control image, the service image is displayed through the upper side display area (namely the upper screen) and the air conditioner interface image is displayed through the lower side display area (namely the lower screen).

If the display status indicates that the aftermarket vehicle image is displayed, the logic chip may generate a fused image based on the control image and the aftermarket vehicle image, where the fused image may include the aftermarket vehicle image and the air conditioning interface image, but may not include the business image. The logic chip can output the fused image to the central control display screen, the central control display screen displays the afterloading vehicle image through the upper side display area after obtaining the fused image, and the lower side display area displays the air conditioner interface image.

According to the technical scheme, the afterloading vehicle image can be displayed through the first display area of the central control display screen, and the second sub-image (such as an air conditioner interface image) is displayed through the second display area of the central control display screen, namely the second display area is not in a black screen state, so that the visual effect of a user is improved, and the user experience is good. The first display area and the second display area can be used simultaneously, and different contents can be displayed respectively without mutual interference. Because the second display area can display the air conditioner interface image, the process of displaying the afterloading vehicle image in the first display area does not influence the display of the air conditioner interface image.

For example, after the air conditioner interface image is displayed through the second display area, the user may perform an operation on the air conditioner interface image, such as an operation of lowering the air conditioner temperature, raising the air conditioner temperature, and the like, and the central control display screen may receive an operation command of the user for the air conditioner interface image. Referring to fig. 1E, the central control display screen may be connected to a logic chip, and the logic chip is connected to an original device (e.g., a processor) of the vehicle central control system, so that the central control display screen may send an operation command to the logic chip after receiving the operation command. After the logic chip receives the operation command, the operation command is directly transmitted to original equipment of the vehicle central control system without being modified. After the original equipment receives the operation command, the original equipment can perform relevant operations on the air conditioner according to the operation command, such as reducing the temperature of the air conditioner or increasing the temperature of the air conditioner, and the operation process is not limited. Obviously, after the logic chip is added in the vehicle central control system, the logic chip can forward the operation command for the air conditioner to the original equipment, so that the original equipment can normally control the air conditioner.

Based on the same application concept as the above method, the embodiment of the present application further provides a vehicle central control system, as shown in fig. 3A, which is a schematic structural diagram of the vehicle central control system, and the vehicle central control system may include but is not limited to: a pre-packaged device, which may include, but is not limited to, a main controller 31 and a logic chip 32, and a post-packaged device, which may include, but is not limited to, a central display screen 33.

In one possible embodiment, the logic chip 32 acquires a control image that is an image output by the original equipment and a aftermarket vehicle image that is an image output by the aftermarket equipment; a fused image is generated from the control image and the aftermarket vehicle image, and the fused image is output to the center control display screen 33. The control image includes a first sub-image and a second sub-image, and the fused image includes a aftermarket vehicle image and the second sub-image. When the central control display screen 33 receives the fused image, the afterloading vehicle image in the fused image is displayed through the first display area of the central control display screen 33, and the second sub-image in the fused image is displayed through the second display area of the central control display screen 33.

In another possible embodiment, the main controller 31 acquires the display state of the center display screen 33, which indicates whether or not the rear-mount vehicle image is displayed. If the display state indicates that the aftermarket vehicle image is displayed, the main controller 31 may output a first instruction to the logic chip 32. If the display state indicates that the aftermarket vehicle image is not displayed, the main controller 31 may output a second instruction to the logic chip 32.

Illustratively, the first instruction is for indicating that an aftermarket vehicle image is desired to be displayed via the central display screen 33 and the second instruction is for indicating that an aftermarket vehicle image is not desired to be displayed via the central display screen 33.

For example, the main controller 31 may acquire the display state indicating information and acquire the display state of the center control display screen 33 according to the display state indicating information. Alternatively, the main controller 31 may acquire an operating state of the vehicle, which may include, but is not limited to, vehicle speed information and/or vehicle steering information, and the main controller 31 may acquire a display state of the center control display screen 33 according to the operating state.

The logic chip 32, upon receiving the first instruction output from the main controller 31, may acquire the control image and the aftermarket vehicle image, and generate a fused image from the control image and the aftermarket vehicle image, and output the fused image to the center control display screen 33. Alternatively, the logic chip 32 may acquire the control image upon receiving the second instruction output from the main controller 31, and output the control image to the center control display 33.

The control image may include a first sub-image and a second sub-image, and the fused image may include the aftermarket vehicle image and the second sub-image. For the first sub-image and the second sub-image, the first sub-image is a service image, and the second sub-image is an air conditioner interface image.

For example, the vehicle center control system may further include a processor (belonging to an original device, not shown in fig. 3A) that may acquire the control image and output the control image to the logic chip 32 so that the logic chip 32 obtains the control image. The main controller 31 acquires the aftermarket vehicle image, and outputs the aftermarket vehicle image to the logic chip 32 so that the logic chip 32 obtains the aftermarket vehicle image. In summary, the logic chip 32 may acquire the control image from the processor and the rear-mounted vehicle image from the main controller 31 when receiving the first instruction. The logic chip 32 may capture the control image from the processor upon receiving the second instruction.

Upon receiving the first instruction, the logic chip 32 generates a fused image from the control image and the aftermarket vehicle image, and outputs the fused image to the center control display screen 33. For example, the logic chip 32 may divide the control image into a first sub-image and a second sub-image and combine the aftermarket vehicle image and the second sub-image into a fused image, or replace the first sub-image in the control image with the aftermarket vehicle image to obtain the fused image.

Illustratively, the logic chip 32 may output the control image directly to the central display screen 33 upon receiving the second instruction, without generating a fused image from the control image and the aftermarket vehicle image.

When the central control display screen 33 receives the fused image output by the logic chip 32, since the fused image includes the aftermarket vehicle image and the second sub-image, the aftermarket vehicle image in the fused image is displayed through the first display region (e.g., the upper side display region) of the central control display screen 33, and the second sub-image in the fused image is displayed through the second display region (e.g., the lower side display region) of the central control display screen 33. When receiving the control image output by the logic chip 32, the central control display screen 33 displays the first sub-image in the control image through the first display area of the central control display screen 33 and displays the second sub-image in the control image through the second display area of the central control display screen 33, because the control image includes the first sub-image and the second sub-image.

On the basis of the above vehicle central control system, referring to fig. 3B, which is another schematic structural diagram of the vehicle central control system, the vehicle central control system may include, but is not limited to, a main controller 31, a logic chip 32, a central control display 33, a body decoder 34, a first signal converter 35, a second signal converter 36, and a third signal converter 37. For example, the body decoder 34 may belong to a rear-mounted device, and the first signal converter 35, the second signal converter 36, and the third signal converter 37 may belong to a front-mounted device.

Illustratively, the interface between the main controller 31 and the logic chip 32 includes an SPI (Serial peripheral interface) and a GPIO (General Purpose Input/Output) interface, and the interface between the body decoder 34 and the logic chip 32 includes a GPIO interface. For convenience of distinction, a GPIO interface between the main controller 31 and the logic chip 32 is referred to as a first GPIO interface, and a GPIO interface between the body decoder 34 and the logic chip 32 is referred to as a second GPIO interface.

The body decoder 34 may be implemented by an MCU (micro controller Unit), or may be implemented by other types of chips, which is not limited to this. For example, the body decoder 34 may acquire the display state indicating information and output the display state indicating information to the main controller 31, so that the main controller 31 acquires the display state of the center control display screen 33 according to the display state indicating information. Alternatively, the body decoder 34 may acquire the running state of the vehicle and output the running state to the main controller 31, so that the main controller 31 acquires the display state of the center control display screen 33 according to the running state.

After acquiring the display state of the central control display screen 33, if the display state indicates that a rear-mounted vehicle image is displayed, the main controller 31 outputs a first instruction to the logic chip 32 through the first GPIO interface, or outputs the first instruction to the vehicle body decoder 34, so that the vehicle body decoder 34 outputs the first instruction to the logic chip 32 through the second GPIO interface. If the display state indicates that the afterloading vehicle image is not displayed, the main controller 31 outputs the second instruction to the logic chip 32 through the first GPIO interface, or outputs the second instruction to the body decoder 34, so that the body decoder 34 outputs the second instruction to the logic chip 32 through the second GPIO interface.

The main controller 31 may manage the logic chip 32 through the SPI interface. For example, the version information is issued to the logic chip 32 through the SPI interface, so that the logic chip 32 is upgraded. The status information (such as normal or abnormal) of the logic chip 32 is queried through the SPI interface, and when the status information is abnormal, the logic chip 32 is repaired. Of course, the above is merely an example, and the management manner is not limited.

The first signal converter 35 may be implemented by a deserializer (e.g., a UB chip), or may be implemented by other types of chips, which is not limited thereto. For example, the first signal converter 35 may convert the serial data format into the parallel data format, for example, the control image output by the processor is in the serial data format, the first signal converter 35 converts the control image in the serial data format into the control image in the parallel data format, without limitation, and outputs the converted control image to the logic chip 32.

When the main controller 31 outputs the aftermarket vehicle image to the logic chip 32, the aftermarket vehicle image may include, but is not limited to, an image in RGB (Red Green Blue ) format, such as an RGB888 image, where the RGB888 image is described by 24 bits (i.e. 3 bytes) for each pixel in the image. When the first signal converter 35 outputs the control image to the logic chip 32, the control image may include, but is not limited to, an image in an LVDS (Low-Voltage Differential Signaling) format.

The logic chip 32 converts the control image in the LVDS format into the control image in the RGB format after receiving the control image in the LVDS format. Upon receiving the first instruction, the logic chip 32 generates a fused image in RGB format from the afterload vehicle image in RGB format and the control image in RGB format, and outputs the fused image in RGB format to the second signal converter 36. Alternatively, the logic chip 32 may directly output the control image in RGB format to the second signal converter 36 when receiving the second instruction.

The second signal converter 36 may be implemented by an LT chip, or may be implemented by other types of chips, which is not limited thereto. For example, the second signal converter 36 may implement conversion of a data format, for example, the control image/fusion image (representing the control image or the fusion image, which is abbreviated as the control image/fusion image in the following) output by the logic chip 32 is in an RGB format, the second signal converter 36 converts the control image/fusion image in the RGB format into the control image/fusion image in an HDMI (high definition Multimedia Interface) format, and the conversion process is not limited thereto, and the second signal converter 36 outputs the converted control image/fusion image to the third signal converter 37.

The third signal converter 37 may be implemented by a serializer (e.g., a UB chip), or may be implemented by other types of chips, which is not limited thereto. For example, the third signal converter 37 may implement conversion from a parallel data format to a serial data format, for example, the control image/fusion image output by the second signal converter 36 is in a parallel data format, the third signal converter 37 may convert the control image/fusion image in the parallel data format into the control image/fusion image in the serial data format, without limitation, and output the converted control image/fusion image to the central control display screen 33.

For example, the third signal converter 37 may also convert the control image/fusion image in the HDMI format into the control image/fusion image in the LVDS format when converting the control image/fusion image in the parallel data format into the control image/fusion image in the serial data format, and the conversion process is not limited.

When receiving the fusion image in the LVDS format, the central control display screen 33 displays the afterloading vehicle image in the fusion image through the first display area, and displays the second sub-image through the second display area. The center control display screen 33, upon receiving the control image in the LVDS format, displays a first sub-image in the control image through the first display area and displays a second sub-image in the control image through the second display area.

In the above embodiment, the Logic chip 32 may be implemented by an FPGA (Field Programmable Gate Array), a CPLD (Complex Programmable Logic Device), or an ASIC (Application Specific Integrated Circuit), and the type of the Logic chip 32 is not limited.

In the above embodiments, the RGB format, the LVDS format, the HDMI format, and the like are all examples of the present application, and the present application does not limit the formats of the control image, the afterloading vehicle image, and the fusion image.

Based on the same application concept as the method described above, a logic chip is also proposed in the embodiment of the present application, as shown in fig. 4A, which is a schematic structural diagram of the logic chip, and the logic chip may include, but is not limited to, a first processing sub-module 321, a second processing sub-module 322, a read-write control sub-module 323, and an image superimposing sub-module 324.

The first processing sub-module 321 is configured to process the control image output by the original device to obtain a processed control image, and output the processed control image to the image superimposing sub-module 324.

The first processing submodule 321 may be an LVDS signal parsing processing submodule (which may be denoted as LVDS _ top), and the first processing submodule 321 may obtain the control image output by the original device, where the control image may be an image in an LVDS format. The first processing submodule 321 can convert the control image in the LVDS format into the control image in the RGB format, and output the control image in the RGB format to the image superimposing submodule.

Illustratively, the First processing submodule 321 may include a FIFO (First Input First Output) queue, such as an LVDS _ RGB _ FIFO queue. The first processing submodule 321 may store the control image in the RGB format in the FIFO queue after converting the control image in the LVDS format into the control image in the RGB format. The image overlay sub-module 324 may read the RGB format control image from the FIFO queue, and for the reading process of the image overlay sub-module 324, see the following embodiments.

Of course, after the first processing sub-module 321 converts the control image in LVDS format into the control image in RGB format, the control image in RGB format may be directly sent to the image superimposing sub-module 324.

For example, the first processing submodule 321 converts the control image in the LVDS format into the control image in the RGB format, which is only an example of processing the control image, and the first processing submodule 321 may also perform other types of processing on the control image, which is not limited in this respect. For example, it is detected whether the data format of the control image is correct, i.e., is in LVDS format, and if so, the control image in LVDS format is converted into the control image in RGB format, otherwise, the control image is discarded. For another example, whether or not an error occurs in the control image is detected, and if an error occurs, the control image is corrected or discarded.

The second processing sub-module 322 is configured to process the aftermarket vehicle image output by the aftermarket device to obtain a processed aftermarket vehicle image, and output the processed aftermarket vehicle image to the read-write control sub-module 323.

The second processing sub-module 322 may be an RGB signal analysis processing sub-module (denoted as avm _ RGB _ top), and the second processing sub-module 322 may acquire an afterloading vehicle image and perform data detection on the afterloading vehicle image, that is, detect whether the afterloading vehicle image is abnormal. If the aftermarket vehicle image is not anomalous, the aftermarket vehicle image may be output to the read-write control sub-module 323. Alternatively, if the aftermarket vehicle image is abnormal, the aftermarket vehicle image may be discarded, or the aftermarket vehicle image may be corrected and output to the read-write control sub-module 323. For example, the data format of the aftermarket vehicle image may be detected, i.e., whether the aftermarket vehicle image is in RGB format. If so, the aftermarket vehicle image is not abnormal, and the aftermarket vehicle image in RGB format is output to the read-write control sub-module 323. If not, the aftermarket vehicle image is abnormal, and the aftermarket vehicle image may be discarded, or the aftermarket vehicle image may be converted into an RGB-formatted aftermarket vehicle image, and the RGB-formatted aftermarket vehicle image may be output to the read-write control sub-module 323.

For another example, the stability of the rear-mount vehicle image, that is, whether the rear-mount vehicle image is unstable data may be detected. If yes, the afterloading vehicle image is abnormal, and the afterloading vehicle image is discarded. If not, the aftermarket vehicle image is not abnormal, and the aftermarket vehicle image is output to the read-write control sub-module 323. For example, if the afterloading vehicle image is incomplete data (if there is no frame header information, the afterloading vehicle image is incomplete data), the afterloading vehicle image is unstable data.

The process of the second processing sub-module 322 performing data detection on the aftermarket vehicle image is only an example of processing the aftermarket vehicle image, and may perform other processing on the aftermarket vehicle image, which is not limited in this respect.

The read-write control sub-module 323 is used for storing the afterloading vehicle image received by the sub-module into the memory.

The read-write control sub-module 323 may be a DDR (Double Data Rate) read-write control sub-module (denoted as DDR _ user _ top), and the read-write control sub-module 323 may obtain the afterloading vehicle image in the RGB format from the second processing sub-module 322, and store the afterloading vehicle image in the RGB format in the memory, where the memory may be a DDR or other types of memory, and the memory is not limited thereto.

For example, the vehicle central control system may further include a DDR, the DDR may be located outside the logic chip 32, and the read-write control sub-module 323 may store the RGB-formatted after-loading vehicle image into the DDR.

The image superimposing sub-module 324 (which may be denoted as img _ integer _ top) outputs the control image received by itself to the central control display screen 33 when receiving the second instruction. The image superposition sub-module 324 sends a reading instruction to the read-write control sub-module 323 when receiving the first instruction, and the read-write control sub-module 323 can read the afterloading vehicle image from the memory (such as DDR) after receiving the reading instruction and output the read afterloading vehicle image to the image superposition sub-module 324; the image overlay sub-module 324 generates a fused image from the control image and the aftermarket vehicle image received by itself, and outputs the fused image to the center control display screen 33.

The image overlay sub-module 324 generates a fused image from the control image and the aftermarket vehicle image, including: segmenting the control image into a first sub-image and a second sub-image, and combining the aftermarket vehicle image and the second sub-image into a fused image; for example, the image overlay sub-module 324 may divide the first N pixels in the control image into a first sub-image, and divide the remaining pixels in the control image except the first N pixels into a second sub-image based on the preconfigured number of pixels N; combining the afterloading vehicle image with the second sub-image to obtain a fused image; illustratively, the number of pixels of the control image is P, the number of pixels of the first sub-image in the control image is N, the number of pixels of the second sub-image in the control image is M, and the sum of M and N is P. Or replacing the first sub-image in the control image by the afterloading vehicle image to obtain a fused image; for example, the image overlay sub-module 324 replaces the previous N pixels in the control image with the aftermarket vehicle image based on the preconfigured number of pixels N, resulting in a fused image; illustratively, the aftermarket vehicle image has a number of pixels N, and the first sub-image in the control image has a number of pixels N.

For example, when receiving the second instruction, the image superimposing sub-module 324 sends a read instruction to the first processing sub-module 321, and after receiving the read instruction, the first processing sub-module 321 reads the control image in the RGB format from the FIFO queue and outputs the control image in the RGB format to the image superimposing sub-module 324. The image superimposing sub-module 324 receives the control image in the RGB format, and outputs the control image to the center control display screen 33.

When the image superimposition sub-module 324 reads the control image from the FIFO queue of the first processing sub-module 321, the image superimposition sub-module 324 can read the control image from the FIFO queue in real time.

For example, when the image superimposing sub-module 324 receives the first instruction, it may send a reading instruction to the first processing sub-module 321, and send a reading instruction to the read-write control sub-module 323.

The first processing sub-module 321 receives the read instruction, reads the control image in the RGB format from the FIFO queue, and outputs the control image in the RGB format to the image superimposing sub-module 324. The read-write control sub-module 323 reads the RGB-format after receiving the read instruction from the memory (e.g., DDR), and outputs the RGB-format after-loading vehicle image to the image superimposition sub-module 324. To this end, the image overlay sub-module 324 may receive the control image in RGB format and the aftermarket vehicle image in RGB format.

Then, the image superimposition sub-module 324 generates a fused image in the RGB format from the afterloading vehicle image in the RGB format and the control image in the RGB format, and outputs the fused image to the center control display screen 33.

Referring to fig. 4B, the logic chip 32 may further include a storage control sub-module 325, and the storage control sub-module 325 may be a storage interface control sub-module (which may be referred to as mig _ top). The functions of the first processing sub-module 321, the second processing sub-module 322, and the image superimposition sub-module 324 are described below with reference to the above embodiments, and are not repeated herein.

The read-write control sub-module 323 may include a write DDR buffer (denoted as wr _ DDR _ buf) and a read DDR buffer (denoted as rd _ DDR _ buf), and the read-write control sub-module 323 acquires the aftermarket vehicle image in RGB format from the second processing sub-module 322, and stores the aftermarket vehicle image in RGB format in the write DDR buffer.

If the aftermarket vehicle image in RGB format is an RGB888 image, it can be described by 24 bits (i.e., 3 bytes) for each pixel in the aftermarket vehicle image, i.e., the pixel value of each pixel is 24 bits. When the RGB-format afterloading vehicle image is stored in the write DDR buffer, the read-write control sub-module 323 converts the pixel value of 24 bits into a pixel value of 32 bits, for example, 8 bits are added in front of the pixel value of 24 bits, where the 8 bits may be 0, and stores the converted afterloading vehicle image in the write DDR buffer.

The storage control sub-module 325 is configured to read the RGB-formatted aftermarket vehicle image from the write DDR buffer of the read-write control sub-module 323, and store the RGB-formatted aftermarket vehicle image in the memory (e.g., DDR).

For example, if the data bit width of the DDR is 16 bits, the storage control submodule 325 reads 32 bits of data from the write DDR buffer of the read/write control submodule 323 and writes 32 bits of data into the DDR every clock cycle, for example, writes 16 bits of data into the DDR on the falling edge of the clock cycle, and writes 16 bits of data into the DDR again on the rising edge of the clock cycle, that is, writes 32 bits of data in one clock cycle. If the data bit width of the DDR is 32 bits, the memory control submodule 325 reads 32 bits of data from the write DDR buffer of the read/write control submodule 323 and writes 32 bits of data into the DDR every clock cycle, for example, writes 32 bits of data into the DDR on a falling edge or a rising edge of the clock cycle.

In summary, it can be seen that the reason why the 24-bit pixel value is converted into the 32-bit pixel value is that since data of 16 or 32 bits is written into the DDR each time, the 32-bit pixel value can be written into the DDR by an integral number of write operations after the 24-bit pixel value is converted into the 32-bit pixel value.

The aftermarket vehicle image is stored to the DDR based on the cooperation of the read-write control sub-module 323 and the storage control sub-module 325, and the subsequent process involves reading the aftermarket vehicle image from the DDR, as will be described below.

The read/write control submodule 323, upon receiving the read command, transmits the read command to the storage control submodule 325. Upon receiving the read instruction, the storage control sub-module 325 reads the aftermarket vehicle image in RGB format from the DDR, and stores the aftermarket vehicle image in the read DDR buffer of the read-write control sub-module 323. For example, if the data bit width of the DDR is 16 bits, the memory control sub-module 325 reads 32 bits of data from the DDR (e.g., reads 16 bits of data from the DDR on the falling edge of the clock cycle, and reads 16 bits of data from the DDR on the rising edge of the clock cycle) and writes 32 bits of data into the read DDR buffer (i.e., writes 32 bits of data via a write operation).

Illustratively, the read-write control sub-module 323 may read the RGB formatted after-market vehicle image from the read DDR buffer and output the RGB formatted after-market vehicle image to the image overlay sub-module 324.

For example, in reading the DDR buffer, for each pixel in the aftermarket vehicle image, it can be described by 32 bits, i.e., the pixel value of each pixel is 32 bits. The read/write control sub-module 323 may convert the 32-bit pixel value into a 24-bit pixel value, for example, by removing the first 8 bits of the 32-bit pixel value. The converted RGB formatted aftermarket vehicle image may then be output to the image overlay sub-module 324.

In the above embodiments, the DDR is involved in a clock cycle, that is, 32 bits of data are written into the DDR or 32 bits of data are read from the DDR every clock cycle. To control the clock cycle of the DDR, a first crystal oscillator (e.g., a 25M crystal oscillator) may be provided for the logic chip 32, and the storage control sub-module 325 may determine the clock cycle of the DDR according to the first crystal oscillator, and then write 32 bits of data into the DDR or read 32 bits of data from the DDR according to the clock cycle.

In a possible embodiment, based on fig. 4A or fig. 4B, the logic chip may further include a system clock generation submodule 326 (not shown in the figure), which may also be denoted as sys _ signal _ gen. The system clock generation submodule 326 is configured to generate a reset signal and a clock signal, and output the reset signal and the clock signal to the logic chip 32, and the functions of the reset signal and the clock signal are not described herein again.

For example, and without limitation, the logic chip 32 may be provided with a second crystal oscillator (e.g., a 27M crystal oscillator) in order to enable the system clock generation submodule 326 to generate the clock signal, and the system clock generation submodule 326 may generate the clock signal according to the second crystal oscillator, such as by dividing the frequency of the second crystal oscillator.

In a possible implementation manner, based on fig. 4A or fig. 4B, the logic chip may further include a status query control sub-module 327 (not shown in the figure), which may also be denoted as spi _ slave _ top.

The status query control submodule 327 is used for interacting with the main controller 31 to manage the logic chip 32. Referring to the foregoing embodiment, when the main controller 31 issues the version information to the logic chip 32 through the SPI interface, the version information may be issued to the status query control submodule 327, and the status query control submodule 327 performs the upgrade on the logic chip 32 according to the version information, without limiting the upgrade process.

The status query control sub-module 327 may determine status information (e.g., normal or abnormal) of the logic chip 32, and record the status information into a register of the logic chip 32, so that the main controller 31 accesses the register of the logic chip 32 through the SPI interface, and reads the status information of the query logic chip 32 from the register.

Of course, the above is only an example of managing the logic chip 32, and the management method is not limited thereto, and the status query control submodule 327 can cooperate with the main controller 31 to implement management of the logic chip 32.

In a possible implementation manner, based on fig. 4A or fig. 4B, the logic chip may further include a main function submodule 328 (not shown in the figure), which may also be denoted as audi _ a6l _ top.

The main function sub-module 328 may be connected to all sub-modules of the logic chip 32 for implementing control and management of the sub-modules. For example, when the logic chip 32 is started, a start signal is first sent to the main function sub-module 328, so that the main function sub-module 328 is in an operating state. After receiving the start signal, the main function sub-module 328 may send a start signal to each sub-module (e.g., the first processing sub-module 321, etc.) of the logic chip 32, so that each sub-module is in an operating state. Of course, the above is merely an example, and no limitation is made thereto.
