Obviously, the drawings described below are some embodiments of the present disclosure.

[0042] 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.

[0043] First, Figure 1 A flow chart of a skylight heating control method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the embodiment of the present disclosure provides a sunroof heating control method, comprising:

[0044] S1: The main control module receives a sunroof heating instruction, generates a first signal, and sends the first signal to the body domain control module.

[0045] Specifically, after the main control module receives the sunroof heating instruction, it generates a first signal and sends the first signal to the body domain control module; the first signal is usually a CAN (Controller Area Network) signal, which is a serial communication protocol. Depending on the vehicle model, the main control module cannot directly send the first signal to the body domain control module, but can forward the first signal to the body domain control module through the central gateway module.

[0046] S2: The first signal is used to control the body domain control module to generate a second signal, and the second signal is used to control the sunroof heating module to heat the sunroof.

[0047] Specifically, after receiving the first signal, the body domain control module generates a second signal, and the second signal is usually a LIN (Local Interconnect Network) signal, which is another serial communication protocol.

[0048] S3: The main control module receives the heating feedback signal generated by the sunroof heating module, and the sunroof heating control is completed.

[0049] Specifically, after the sunroof heating module starts to heat the sunroof, a heating feedback signal is generated, and the heating feedback signal is used to feedback to the main control module that the sunroof heating module has started to heat the sunroof. The heating feedback signal can be directly sent from the sunroof heating module to the main control module. Of course, considering the stability, feasibility and cost of communication, the heating feedback signal is usually fed back layer by layer from the sunroof heating module until it is fed back to the main control module.

[0050] In the embodiment of the present disclosure, after the main control module receives the sunroof heating instruction, it forwards the first signal to the body domain control module through the central gateway module. After receiving the first signal, the body domain control module sends a second signal to the sunroof heating module to control the sunroof heating module to heat the sunroof. When the sunroof heating module starts heating the sunroof, it sends a heating feedback signal to the main control module. In this way, the sunroof is heated under the control of the main control module, and the heating feedback signal is received when the sunroof starts heating, confirming that the sunroof heating module starts working.

[0051] In some examples, the main control module receives the sunroof heating instruction, generates a first signal, and sends the first signal to the body domain control module, specifically including:

[0052] S11: The main control module receives a sunroof heating instruction, generates a first signal, and sends the first signal to the central gateway module.

[0053] S12: The first signal is received by the central gateway module and forwarded to the body domain control module.

[0054] In some examples, the first signal is a CAN signal, which is transmitted using a CAN bus, and the second signal is a LIN signal, which is transmitted using a LIN signal, mainly through a LIN bus. The LIN bus is a low-cost serial communication network defined for automotive distributed electronic systems, also known as a local interconnect network bus. The LIN bus has simple hardware requirements, and only requires a UART / SCI interface, supplemented by a simple driver to implement the LIN protocol. In addition, the LIN bus uses a single-line transmission, which reduces the complexity of wiring and reduces installation and maintenance costs; the network architecture is simple, the master node is responsible for communication control, and the slave node responds to the master node's instructions. This architecture makes the communication process clearer and easier to manage; in particular, the LIN bus supports a variety of data types and message formats, which can meet the communication needs between different in-vehicle modules, and it can also be integrated with other automotive network protocols (such as the CAN bus), improving the overall flexibility and scalability of the system. The CAN bus and the LIN bus are set up in the car at the same time. The LIN line is used as an auxiliary network to provide supplementary services for the main automotive networks such as the CAN bus, and a hierarchical network structure is realized, thereby achieving reasonable use of network resources, improving the flexibility of line layout, and reducing costs.

[0055] In some examples, the main control module receives the heating feedback signal generated by the sunroof heating module, and the sunroof heating control is completed, specifically including:

[0056] S31: When the sunroof heating module starts to heat the sunroof, it sends a heating feedback signal to the body domain control module.

[0057] S32: The body domain control module sends the received heating feedback signal to the central gateway module, and the central gateway module feeds back the heating feedback signal to the main control module.

[0058] Specifically, the heating feedback signal sent by the sunroof heating module to the body domain control module may be a LIN signal. The body domain control module converts the heating feedback signal from the LIN signal into a CAN signal, and forwards the heating feedback signal converted into the CAN signal to the main control module via the central gateway module.

[0059] In the second aspect, based on the same inventive concept, the disclosed embodiment also provides a sunroof heating control system, the system comprising: a main control module, a body domain control module and a sunroof heating module. The main control module is used to receive a sunroof heating instruction, generate a first signal, and send the first signal to the body domain control module; the body domain control module is used to generate a second signal under the control of the first signal, and send the second signal to the sunroof heating module; the sunroof heating module is used to start heating the sunroof under the control of the second signal, and send a heating feedback signal to the main control module when starting to heat the sunroof.

[0060] In some examples, the sunroof heating control system also includes: a central gateway module; the central gateway module is used to receive a first signal sent by the main control module and forward the first signal to the body domain control module.

[0061] In some examples, the sunroof heating control system also includes: an intelligent vehicle-mounted terminal module; the intelligent vehicle-mounted terminal module is used to receive a sunroof heating command, wake up the car, and set the car power gear to the ACC gear or the ON gear; and send the received sunroof heating command to the main control module.

[0062] Embodiment 1:

[0063] In the present disclosure, Figure 2 As shown, in order to realize intelligent control of the car, the car APP is used to send the sunroof heating command to the main control module.

[0064] In the disclosed embodiment, the car APP can automatically identify the weather through the Internet and other channels. When the weather is rainy, foggy or cold, the car APP will remind the owner whether to turn on the sunroof heating function. The owner can turn on the sunroof heating through the car APP according to the future needs of using the car.

[0065] In the disclosed embodiment, the car owner can turn on the sunroof heating through the car APP, and the intelligent vehicle terminal module receives the sunroof heating command sent by the car APP through mobile devices such as mobile phones and tablets. After receiving the sunroof heating command, the intelligent vehicle terminal module wakes up the car and puts the car power gear in the ACC gear or the ON gear. In the ACC gear, the car power supply mainly supplies power to some electrical devices, such as audio, air conditioning, cigarette lighter, etc. These devices can be used independently without starting the engine. In the ON gear, the car's engine and most of the car's electrical equipment will start to supply power.

[0066] It is understandable that to achieve car sunroof heating, the car power gear needs to be in the ACC gear or the ON gear.

[0067] Furthermore, the intelligent vehicle terminal module may be a T-BOX (Telematics BOX), which is an intelligent vehicle terminal of the Internet of Vehicles system. It usually communicates with the vehicle ECU (electronic control unit), collects vehicle data and sends it to the background system or the cloud, and receives background instructions to control the vehicle.

[0068] In the disclosed embodiment, the intelligent vehicle terminal module wakes up the vehicle, sets the vehicle power gear to the ACC gear or the ON gear, and then sends the received sunroof heating instruction to the main control module.

[0069] In the disclosed embodiment, the main control module receives the sunroof heating instruction, generates a first signal, and sends the first signal to the central gateway module; the central gateway module receives and forwards the first signal to the body domain control module. After receiving the first signal, the body domain control module generates a second signal, and the second signal controls the sunroof heating module to heat the sunroof.

[0070] Furthermore, the first signal is a CAN signal, which is transmitted using the CAN bus, and the second signal is a LIN signal, which is transmitted using the LIN signal, mainly through the LIN bus. The LIN bus is a low-cost serial communication network defined for automotive distributed electronic systems, also known as a local interconnect network bus. The LIN bus has simple hardware requirements, requiring only a UART (Universal Asynchronous Receiver / Transmitter) interface and an SCI (Serial Communication) interface, supplemented by a simple driver to implement the LIN protocol, and the LIN bus uses a single-line transmission, which reduces the complexity of wiring and reduces installation and maintenance costs; the network architecture is simple, the master node is responsible for communication control, and the slave node responds to the master node's instructions. This architecture makes the communication process clearer and easier to manage; in particular, the LIN bus supports a variety of data types and message formats, which can meet the communication requirements between different in-vehicle modules, and it can also be integrated with other automotive network protocols (such as the CAN bus), improving the overall flexibility and scalability of the system. The CAN bus and the LIN bus are set up in the car at the same time. The LIN line is used as an auxiliary network to provide supplementary services for the main automotive networks such as the CAN bus, and a hierarchical network structure is realized, thereby achieving reasonable use of network resources, improving the flexibility of line layout, and reducing costs.

[0071] In the disclosed embodiment, when the sunroof heating module starts to heat the sunroof, it sends a heating feedback signal to the body domain control module. After receiving the heating feedback signal, the body domain control module sends the heating feedback signal to the central gateway module, and the central gateway module feeds the heating feedback signal back to the main control module. After receiving the heating feedback signal, the main control module forwards the heating feedback signal to the mobile phone APP through the intelligent vehicle terminal module, and the mobile phone APP displays a notification or pop-up window of "sunroof heating is turned on" to the user.

[0072] Furthermore, the heating feedback signal sent by the sunroof heating module to the body domain control module may be a LIN signal. The body domain control module converts the heating feedback signal from a LIN signal into a CAN signal, and forwards the heating feedback signal converted into a CAN signal to the main control module via the central gateway module.

[0073] Embodiment 2:

[0074] In the present disclosure, Figure 3As shown, when the car meets the preset conditions, the sunroof heating command can be issued to the main control module through the car's central control screen or soft switch. The preset conditions include that the car is in the starting state. It is understandable that to achieve the car sunroof heating, the car power gear needs to be in the ACC gear or ON gear. In the ACC gear, the car power supply mainly supplies power to some electrical devices, such as audio, air conditioning, cigarette lighter, etc. These devices can be used independently without starting the engine. In the ON gear, the car's engine and most of the car's electrical devices will start to supply power.

[0075] In the disclosed embodiment, a sunroof heating instruction is issued to the main control module through the central control screen or soft switch of the car. The main control module receives the sunroof heating instruction, generates a first signal, and sends the first signal to the central gateway module; the central gateway module receives and forwards the first signal to the body domain control module. After receiving the first signal, the body domain control module generates a second signal, and the second signal controls the sunroof heating module to heat the sunroof.

[0076] Furthermore, the first signal is a CAN signal, which is transmitted using the CAN bus, and the second signal is a LIN signal, which is transmitted using the LIN signal, mainly through the LIN bus. The LIN bus is a low-cost serial communication network defined for automotive distributed electronic systems, also known as a local interconnect network bus. The LIN bus has simple hardware requirements, requiring only a UART (Universal Asynchronous Receiver / Transmitter) interface and an SCI (Serial Communication) interface, supplemented by a simple driver to implement the LIN protocol, and the LIN bus uses a single-line transmission, which reduces the complexity of wiring and reduces installation and maintenance costs; the network architecture is simple, the master node is responsible for communication control, and the slave node responds to the master node's instructions. This architecture makes the communication process clearer and easier to manage; in particular, the LIN bus supports a variety of data types and message formats, which can meet the communication requirements between different in-vehicle modules, and it can also be integrated with other automotive network protocols (such as the CAN bus), improving the overall flexibility and scalability of the system. The CAN bus and the LIN bus are set up in the car at the same time. The LIN line is used as an auxiliary network to provide supplementary services for the main automotive networks such as the CAN bus, and a hierarchical network structure is realized, thereby achieving reasonable use of network resources, improving the flexibility of line layout, and reducing costs.

[0077] In the disclosed embodiment, when the sunroof heating module starts to heat the sunroof, it sends a heating feedback signal to the body domain control module. After receiving the heating feedback signal, the body domain control module sends the heating feedback signal to the central gateway module, which then feeds the heating feedback signal back to the main control module. After receiving the heating feedback signal, the main control module controls the central control screen to display a notification or pop-up window indicating that the "sunroof heating is on" to the user.

[0078] Furthermore, the heating feedback signal sent by the sunroof heating module to the body domain control module may be a LIN signal. The body domain control module converts the heating feedback signal from a LIN signal into a CAN signal, and forwards the heating feedback signal converted into a CAN signal to the main control module via the central gateway module.

[0079] Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
