Description

Technical Field

[0001] The present invention relates to the technical field of automobile intelligent control, and in particular to a method, device and system for detecting items in a vehicle refrigerator. Background Art

[0002] Before 2019, most automotive electronic architectures adopted a distributed architecture, and various functions were usually implemented by independent ECUs (Electronic Control Units), each of which was responsible for a specific function. The entire vehicle communicated based on CAN (Controller Area Network) and LIN (Local Interconnect Network) buses. This architecture led to a highly decentralized system, increasing hardware costs, system complexity, and integration difficulty. Function updates and iterations often require the coordinated modification of multiple controllers, and the software for each ECU was developed by different suppliers, resulting in a long and difficult software change cycle.

[0003] Around 2020, with the development of vehicle-mounted systems, the electronic architecture was upgraded to a domain-centralized architecture, dividing the vehicle functions into power domain, chassis domain, cockpit domain, autonomous driving domain, and body domain, and concentrating the scattered ECU functions into the domain controller, based on the CAN bus and superimposed with Ethernet communication.

[0004] The upgrade of electronic architecture provides the hardware conditions for the introduction of SOA (Service-Oriented Architecture), and the application of in-vehicle Ethernet provides the network conditions for the introduction of SOA architecture.

[0005] Automotive SOA organizes the underlying capabilities of the entire vehicle's intelligence, SOA-ing the underlying hardware capabilities and various functions of the vehicle, dividing them into different services and splitting them into smaller granular interfaces. These services are designed with interfaces based on SOA standards and communicate based on SOA standard protocols. In this way, each service component can access each other, thus expanding the combination of services.

[0084] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0085] The disclosed embodiment adopts a domain-centralized electronic architecture, based on the CAN bus, superimposed Ethernet communication, and based on the SOA service architecture to realize the item detection function of the vehicle refrigerator. The vehicle refrigerator item detection function is abstracted into an independent atomic service, which can be called by multiple consumers who also use the SOME / IP (Scalable service-oriented middleware over IP) protocol, and can be adapted to various application scenarios, where the consumer can be the vehicle machine ICU (Infotainment Computing Unit, infotainment domain controller), voice control system and / or mobile phone APP, and the consumer runs on the user terminal.

[0086] The refrigerator item detection atomic service in the present disclosure includes two methods and two events. The methods are opening the item detection service (Icb_ItemLeft_Open) and closing the item detection service (Icb_ItemLeft_Close). The events are the item detection switch status (Icb_ItemLeft_Sts) and the item detection status (Icb_ItemCheck_Sts).

[0087] The car ZCU (Zone Control Unit) is used as a server. The ZCU also has a gateway function, i.e. a service-oriented gateway (using the SOME / IP protocol communication middleware). Considering the economy, the ZCU communicates with the vehicle ICU and the mobile phone APP via Ethernet to complete the publishing, calling and subscription of services. The ZCU and CHC (Cooling and Heating Controller) communicate via CAN, and the ZCU completes the conversion of Ethernet data and CAN signals through its own gateway function.

[0088] Figure 1 A schematic diagram showing a service consumer invoking an object detection service according to an embodiment of the present disclosure. Figure 2 A flow chart of a method for detecting items in a vehicle refrigerator according to an embodiment of the present disclosure is shown. Figure 3 A timing diagram of a vehicle refrigerator article detection method according to an embodiment of the present disclosure is shown. Figure 1 , Figure 2 and Figure 3 The method for detecting items in a vehicle refrigerator disclosed in the present invention is described.

[0089] The method for detecting items in a vehicle refrigerator according to the embodiment of the present disclosure comprises the following steps:

[0090] Step 101: ICU receives a task to start the vehicle refrigerator item detection function;

[0091] In actual operation, Figure 2 As shown, the user can turn on the refrigerator item detection function by sliding the soft switch displayed on the ICU screen in the car to the right.

[0092] Step 102: ICU sends a query request for starting the item detection service to ZCU via Ethernet.

[0093] Here, ZCU acts as a service-oriented gateway and has a service registry, in which there are information about opening item detection service (Icb_ItemLeft_Open), closing item detection service (Icb_ItemLeft_Close) and corresponding service interface information.

[0094] Step 103: ZCU receives the opening item detection service query request sent by ICU via Ethernet.

[0095] Step 104: The ZCU queries the service interface information for opening the item detection service from the service registration table.

[0096] The service registry contains service name and service interface information.

[0097] Step 105: ZCU sends the queried opening item detection service interface information to ICU.

[0098] Step 106: ICU receives the opening item detection service interface information sent by ZCU via Ethernet.

[0099] Step 107: Based on the SOME / IP protocol, the ICU uses the queried information about the item detection service interface to send a remote item detection service request to the ZCU via Ethernet, and subscribes to item detection switch status events and item detection status events.

[0100] Step 108: ZCU receives the remote call request to start the item detection service sent by ICU.

[0101] Step 109: ZCU parses the remote call start item detection service request and assembles it into a start item detection CAN signal.

[0102] Here, the assembled opening item detection CAN signal may be: Icb_AppItemsLeft_Req=0x1:Open / 0x2:Close.

[0103] Step 110: The ZCU sends the assembled opened item detection CAN signal to the CHC via the CAN bus.

[0104] Step 111: CHC receives the opened object detection CAN signal sent by ZCU via the CAN bus.

[0105] Step 112: The CHC drives the refrigerator to start the object detection function according to the received CAN signal, and drives the refrigerator to perform object detection.

[0106] Specifically, after receiving the opened object detection CAN signal, the CHC converts the opened object detection CAN signal into the internal control logic of the refrigerator, drives the refrigerator to turn on the object detection function, and drives the refrigerator to perform object detection.

[0107] Step 113: The refrigerator turns on the item detection function, performs item detection therein, and obtains the item detection switch state and the item detection state.

[0108] Item detection switch status (Icb_AppItemsLeft_Sts=0x1:Open / 0x2:Close), where a value of 1 means the item detection function is on, and a value of 2 means the item detection function is off.

[0109] Item detection status (Icb_AppItemsLeftcheck_Sts=0x1:Yes / 0x2:No), where a value of 1 indicates that there are items in the refrigerator, and a value of 2 indicates that the refrigerator is empty.

[0110] It should be noted that the refrigerator can also trigger the object detection function when it detects that the refrigerator door is opened or closed.

[0111] Step 114: The refrigerator sends the item detection switch status and the item detection status to the CHC via a hard line.

[0112] Step 115: The CHC receives the object detection switch state and the object detection state sent by the refrigerator through the hard line and assembles them into an object detection switch state CAN signal and an object detection state CAN signal.

[0113] Step 116: The CHC periodically sends the object detection switch status CAN signal and the object detection status CAN signal to the ZCU via the CAN bus.

[0114] Here, the CHC periodically sends the object detection switch state CAN signal and the object detection status CAN signal to ensure that the state of the soft switch follows the refrigerator object detection switch state, so that the on and off buttons of the soft switch can be used normally.

[0115] Step 117: The ZCU receives the object detection switch status CAN signal and the object detection status CAN signal sent by the CHC.

[0116] Step 118: ZCU determines whether the item detection switch status value and the item detection status value have changed. If so, the item detection switch status event and the item detection status event are triggered, and the item detection switch status CAN signal and the item detection status CAN signal are encapsulated and published to the user terminal via Ethernet; if there is no change, ZCU continues to judge.

[0117] Step 119: The ICU receives the item detection switch status and item detection status issued by the ZCU via Ethernet.

[0118] Specifically, the ICU receives the item detection switch status value and the item detection status value issued by the ZCU.

[0119] Step 120: The ICU outputs the switch status of the object detection function based on the received object detection switch status; based on the received object detection status, the ICU outputs the state of the refrigerator, wherein the state of the refrigerator includes: empty and loaded.

[0120] When the item detection switch status released by ZCU is on, the soft switch on the ICU interface remains at the rightmost position, indicating that the item detection function is on; when the item detection switch status released by ZCU is off, the soft switch on the ICU interface remains at the leftmost position, indicating that the item detection function is off; when the item detection switch status released by ZCU is on and the item detection status is empty, ICU can pop up a text reminder "The refrigerator is detected to be empty, please close the refrigerator in time", and there can be a "Whether to turn off the refrigerator item detection function" button on the pop-up box, or a separate voice reminder can be given, or a voice reminder can be given at the same time as a pop-up text reminder.

[0121] At this point, the detection of items in the car refrigerator is completed.

[0122] In addition, when the user clicks to turn off the refrigerator item detection function or when the user responds to the voice to turn off the refrigerator item detection function, in actual use operations, such as Figure 2 As shown, the user slides the soft switch displayed on the ICU screen in the car to the left to trigger the refrigerator item detection function shutdown task. The above-mentioned vehicle refrigerator item detection method also includes:

[0123] Step 121: ICU receives a task to shut down the refrigerator item detection function.

[0124] Step 122: ICU sends a query request for closing the item detection service to ZCU via Ethernet.

[0125] Step 123: The ZCU receives a query request for closing the item detection service sent by the user terminal via Ethernet.

[0126] Step 124: The ZCU queries the closed item detection service interface information from the service registration table.

[0127] Step 125: ZCU sends the queried closed item detection service interface information to ICU.

[0128] Step 126: The ICU receives the closed item detection service interface information sent by the zone controller via Ethernet.

[0129] Step 127: Based on the SOME / IP protocol, the ICU uses the queried closed item detection service interface information to remotely call the closed item detection service.

[0130] Step 128: The ZCU receives a remote call request for closing the object detection service sent by the user terminal via Ethernet.

[0131] Step 129: ZCU parses the remote call service request for shutting down object detection and assembles it into a CAN signal for shutting down object detection.

[0132] Step 130: The ZCU sends the assembled closed object detection CAN signal to the CHC.

[0133] Step 131: CHC receives the closed object detection CAN signal sent by ZCU via the CAN bus.

[0134] Step 132: The CHC drives the refrigerator to close the object detection according to the received closed object detection CAN signal.

[0135] Specifically, after receiving the closed object detection CAN signal, the CHC converts the closed object detection CAN signal into the internal control logic of the refrigerator to drive the refrigerator to close the object detection.

[0136] Step 133: CHC periodically sends the object detection switch status CAN signal to ZCU.

[0137] Here, CHC periodically sends the detection switch status CAN signal to make the state of the soft switch follow the refrigerator item detection switch state, so that the on and off buttons of the soft switch can be used normally.

[0138] Step 134: The ZCU receives the object detection switch status CAN signal sent by the CHC.

[0139] Step 135: ZCU determines whether the object detection switch status value has changed. If it has changed, it triggers an object detection switch status event, encapsulates the object detection switch status CAN signal, and publishes it to the user terminal ICU via Ethernet.

[0140] Step 136: ICU receives the item detection switch status issued by ZCU.

[0141] The process of calling the refrigerator item detection service by mobile phone APP and voice control system is the same, and only the same API (Application Programming Interface) needs to be called.
