The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Just as background art says, at present along with the development of intelligent vehicle-mounted technology, the separation of passenger cabin host computer and display end has become the development trend of the passenger cabin of vehicle, and passenger cabin host computer control unit receives the CAN signal that on-vehicle system sent through the CAN transceiver, and the analysis CAN signal controls passenger cabin host computer system on-chip transmission video stream to the serializer, and the serializer is mated with deserializer 6 of display end, and real with the video stream transmission to the display screen end, make the picture that the display screen shows the safe state that characterizes the vehicle in the video stream.
The inventor finds that the cabin host system-on-chip does not reach the ASILB standard, when the cabin host and the display screen end carry out data transmission, some abnormal interference may cause picture information in a transmitted video stream to be wrong, and the picture displayed in the display screen cannot be guaranteed to be in the current safety state of a vehicle; when the transmission signal is abnormal or broken, the display screen cannot display the pictures in the transmitted video stream, the current state of the vehicle cannot be displayed, the display end does not have extra measures to compare and verify the display content in the video stream, and an error compensation mechanism is not provided.
In view of this, the present disclosure provides a method and a system for displaying a vehicle safety state, which compare a state picture of a vehicle in a video stream signal, and determine whether to display the state picture in the video stream signal according to a comparison result, so as to verify the state picture in the video stream signal, ensure that a content displayed on a display screen can reflect a current state of the vehicle, and improve reliability of the content in the display screen.
FIG. 1 is a flow chart illustrating a method of displaying a vehicle safety status, according to an exemplary embodiment, the method comprising:
in step S101, a video stream signal transmitted by a cabin host of a vehicle is received.
In step S102, the video stream signal is analyzed to obtain a status picture of the vehicle, where the status picture includes icon statuses of various function icons of the vehicle.
In step S103, the state picture is compared with a first pre-stored state picture to obtain a comparison result, where the first pre-stored state picture includes a current icon state of each function icon of the vehicle.
In step S104, the first pre-stored state picture is displayed when the icon state in the comparison result representation state picture is inconsistent with the current icon state in the first pre-stored state picture.
The first pre-stored state picture comprises icon states of all function icons of the vehicle in different states, whether the current state of the vehicle can be represented by the state picture can be determined by comparing the state picture with the first pre-stored state picture, when the icon state in the state picture represented by the comparison result is inconsistent with the current icon state in the first pre-stored state picture, the current state of the vehicle cannot be represented by the state picture, the first pre-stored state picture is displayed, the current state of the vehicle can be represented by the displayed picture, and the reliability of display content is improved.
For example, taking a display end as an example, when a vehicle is in a normal driving state, receiving a video stream signal sent by a cabin host of the vehicle, and performing analysis processing on the video stream signal to obtain a state picture of the vehicle, where the state picture includes an icon state of each function icon of the vehicle; comparing the state picture with a first pre-stored state picture to obtain a comparison result, wherein the first pre-stored state picture comprises the current icon state of each function icon when the vehicle is in a normal driving state; and under the condition that the icon state in the comparison result representation state picture is inconsistent with the current icon state in the first pre-stored state picture, displaying the first pre-stored state picture, so that personnel in the vehicle can obtain the current icon state of each function icon of the vehicle through the displayed first pre-stored state picture, and further determine that the vehicle is in a normal driving state.
In order to make the method for displaying the safe state of the vehicle provided by the present disclosure more understandable to those skilled in the art, the above steps are exemplified in detail below.
In an embodiment, the step S103 of comparing the state image with the first pre-stored state image includes:
and comparing the pixel, color and size of each function icon of the vehicle in the state picture and the first prestored picture respectively.
Specifically, image Comparison is performed between the state picture and the first pre-stored picture, whether the pixels, colors, sizes and the like of the function icons of the vehicle in the state picture are consistent with those of the function icons of the vehicle in the first pre-stored picture is determined, and Comparison between the state picture and the first pre-stored state picture is achieved.
The state picture is compared with the first pre-stored picture, so that the state picture can be checked, the state picture is still displayed when the state picture is wrong due to the fact that the cabin host machine is interfered, the displayed state picture cannot be consistent with the current state of the vehicle, safety accidents caused by errors of the displayed picture content are avoided, and the reliability of the displayed content is improved.
In one embodiment, the method further comprises:
and displaying a second pre-stored state picture under the condition that a video stream signal sent by a cabin host of the vehicle is not received within a preset time length, wherein the second pre-stored state picture comprises the icon state of each function icon of the vehicle in a communication interruption state.
The preset duration can be preset according to the communication time required by the actual communication process of the cockpit host and the display terminal under the premise of following the communication protocol of the cockpit host and the display terminal, and the preset duration is not specifically limited in the present disclosure.
For example, in a case that a video stream signal sent by a cabin host of a vehicle is not received within 30s, and it is determined that the vehicle is in a communication interruption state, an icon state including various function icons of the vehicle in the communication interruption state is displayed, where the case of causing the communication interruption of the vehicle includes: the transmission path between the cockpit main unit and the display end is damaged, the serializer of the cockpit main unit is damaged, or the deserializer 6 of the display end is damaged.
