Description

Technical Field

[0001] The utility model relates to the technical field of vehicle control, and particularly relates to a cabin-driving control system and a vehicle. Background Art

[0002] With the evolution of the EEA (Electrical / Electronic Architecture) architecture, the cabin controller gradually moves towards the cabin-driving integrated central computing platform, resulting in an increase in the size of the cabin controller compared with before, and increasing pressure on the in-vehicle layout. Subsequently, in external power amplifier devices, such as the audio sub-card, the number of channels of the multi-channel boost amplifier increases, such as 20 channels, that is, there are 20 connection channels for the power amplifier devices. This leads to the need for a sufficiently large area in the design of the external power amplifier device because multiple amplifiers need to be arranged inside it, resulting in a large occupied area of the peripheral circuit of the power amplifier device and increasing the difficulty of the layout of the vehicle architecture. Summary of the Utility Model

[0003] In view of this, the utility model provides a cabin-driving control system and a vehicle to solve the problem that the peripheral circuit of the power amplifier device occupies a large area.

[0004] In a first aspect, the utility model provides a cabin-driving control system, which includes: a cabin-driving controller, an audio sub-card, an inter-board connector, and at least one audio device. Among them, the inter-board connector is arranged between the cabin-driving controller and the audio sub-card and is used to connect the cabin-driving controller and the audio sub-card;

[0005] Among them, the cabin-driving controller is used to generate an audio signal and a vehicle control signal, and output the audio signal and the vehicle control signal to the inter-board connector;

[0006] The inter-board connector is used to receive the audio signal and the vehicle control signal, and transmit the audio signal and the vehicle control signal to the audio sub-card;

[0007] The audio sub-card includes an audio DSP module and at least one amplifier; the audio DSP module includes a signal input end and a signal output end. The signal input end is used to connect the inter-board connector, and the signal output end is used to connect the at least one amplifier. Each amplifier is connected to an audio device;

[0008] The audio DSP module is used to receive the audio signal and the vehicle control signal sent by the inter-board connector, and transmit them to the at least one amplifier. Each amplifier is used to send an audio signal to the audio device connected to it.

[0009] In combination with the first aspect, in a possible implementation, the cabin-driving controller includes: a cockpit chip and a microprocessor MCU, and the cockpit chip and the microprocessor MCU are respectively connected to the inter-board connector; the cockpit chip is used to generate and output the audio signal to the inter-board connector; the microprocessor MCU is used to generate and output the vehicle control signal to the inter-board connector.

[0010] In combination with the first aspect, in another possible implementation, the cabin-driving controller further includes a CAN bus communication module, and the CAN bus communication module is connected to the CAN network.

[0011] In combination with the first aspect, in yet another possible implementation, the cabin-driving control system further includes an external power supply, the cabin-driving controller further includes a first power module, and the audio sub-card further includes a second power module;

[0012] The first power module and the second power module are respectively connected to the external power supply, and the external power supply is used to supply power to the cabin-driving controller through the first power module and to supply power to the audio sub-card through the second power module.

[0013] In combination with the first aspect, in yet another possible implementation, the cabin-driving control system further includes a heat dissipation structure, and the heat dissipation structure is respectively connected to the cabin-driving controller and the audio sub-card for dissipating heat from the cabin-driving controller and the audio sub-card.

[0014] In combination with the first aspect, in yet another possible implementation, the heat dissipation structure includes:

[0015] Pipes: The pipes are respectively connected to the cabin-driving controller and the audio sub-card through connectors, and the shape of the pipes matches that of the cabin-driving controller and the audio sub-card;

[0016] Working fluid: The fluid located in the pipes has high heat conduction performance;

[0019] Controllers: Connected to the pipes and the heat sinks, used to control the flow of the working fluid in the pipes and to control the heat dissipation of the heat sinks.

[0020] In this implementation, a heat dissipation structure is set in the cabin-driving control system. By having the working fluid flow through the pipes, active heat dissipation for the cabin-driving controller and the audio sub-card is achieved, replacing the passive heat dissipation scheme to realize the heat dissipation of the integrated power amplifier system.

[0021] In a second aspect, the present utility model further provides a vehicle, which includes the cabin-driving control system described in the foregoing first aspect or any implementation manner of the first aspect.

[0022] For the cabin-driving control system and the vehicle provided by the patent of the present utility model, the board-to-board connector, i.e., the B2B connector, replaces the original A2B connector and is used to connect the cabin-driving controller and the Audio daughter card. Since the A2B signal is no longer transmitted between the cabin-driving controller and the Audio daughter card, there is no need to set an A2B module and an MCU on the Audio daughter card, and instead, it can be directly transmitted through the DSP signal, eliminating modules such as the A2B module and the MCU, avoiding the problem of excessive single-board area caused by integrating a multi-channel power amplifier system, and at the same time solving the problem of excessive cost caused by the dependence of the PCB cost on the complex cabin-driving system.

[0023] In addition, through the low-speed B2B connector, the cost of the transmission modules (wiring harness, A2B transceiver) required for the traditional power amplifier system to be pulled away from the cockpit system can also be saved. By integrating the cabin-driving controller and the power amplifier system, the MCUs, communication modules, heat dissipation modules, etc. of the cockpit and the power amplifier can be combined, thereby reducing the complexity of the overall system and bringing about a reduction in the vehicle cost.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Currently, in-vehicle multi-channel power amplifier systems all exist in an independent form, and there is no solution for integrating a multi-channel boost power amplifier system into a cockpit controller. For example, the number of channels integrated in a general cockpit control system is 4 to 8 channels, which does not meet the actual requirements because 12 channels, 16 channels or more are needed.

[0031] See Figure 1 , which is a cockpit-driving control system provided in this embodiment. The system includes a cockpit-driving controller, an Audio sub-card, at least one audio device, an external power supply, a CAN network harness, etc.

[0032] Among them, the cockpit-driving controller and the Audio sub-card are connected by an A2B harness. Specifically, the A2B harness, that is, A2B (Automotive Audio Bus) is a digital audio bus standard for automotive audio systems, aiming to provide a high-quality, low-latency audio transmission solution. Further, the A2B harness is a high-bandwidth, bidirectional, digital audio bus that can connect various audio devices in a vehicle, such as microphones, speakers, digital signal processors (DSPs), etc. In addition, the A2B harness is usually composed of an unshielded twisted pair (UTP), and transmits information such as audio data and clock to each node in the audio system through a single connection.

[0033] As Figure 1 shown, the cockpit-driving controller includes: a cockpit SOC, a microprocessor MCU, an A2B module, a power supply module, a CAN bus, etc. In addition, the Audio sub-card includes: an A2B module, an audio DSP module, a microcontroller unit (MCU), at least one AMP (Amplifier), a boost power supply circuit, a power supply module, etc.

[0034] One end of the A2B wire harness is connected to the A2B module of the cabin-driving controller, and the other end is connected to the A2B module of the Audio sub-card. The signal transmission path is as follows: The System on Chip (SOC) in the cockpit generates an audio signal and transmits the audio signal to the A2B module. The A2B module transmits the audio signal to the A2B module of the Audio sub-card through the A2B wire harness, and the A2B module of the Audio sub-card transmits it to the audio DSP module after receiving it.

[0035] In addition, the above signal transmission also includes the transmission process of the control signal. Specifically, the microcontroller unit (MCU) of the cabin-driving controller generates a control signal, and uses the A2B module to transmit it to the A2B module of the Audio sub-card through the A2B wire harness. After receiving it, the A2B module transmits the control signal to the audio DSP module and at least one AMP.

[0036] In addition, the microcontroller unit (MCU) of the above cabin-driving controller also generates another control signal and transmits it to the CAN bus module of the Audio sub-card through the Controller Area Network (CAN) bus.

[0037] It should be noted that in the process of transmitting the audio signal and / or control signal through the A2B module, the A2B model first needs to encapsulate the received audio signal and / or control signal into the A2B signal format, and then send it to the external power amplifier A2B module through the A2B wire harness. The A2B module of the Audio sub-card splits the received A2B signal into an audio signal and a controller signal, and sends them to the audio DSP module and the MCU inside the external power amplifier respectively.

[0038] Since multiple AMPS need to be set in the Audio sub-card to connect multiple channels, such as 12 or 16 channels, but the space range of the Audio sub-card is limited, increasing the AMPS for multiple channels at the cost of expanding the area of the Audio sub-card will cause an increase in cost and a greater difficulty in the layout of the vehicle architecture.

[0039] To solve this problem, this embodiment provides a cabin-driving control system, as Figure 2 shown. The Audio sub-card in the cabin-driving control system does not include a microcontroller unit (MCU), a CAN bus, and an A2B module, thus saving space, enabling other AMPS to be added in this space, without increasing or expanding the area of the Audio sub-card, and the additional AMPS can establish channels with at least one audio device, thereby achieving a 12- or 16-channel cabin-driving control system.

[0040] The technical solution provided by this embodiment will be described in detail below.

[0041] See Figure 2 which is a schematic structural diagram of a cabin-driving control system provided in this embodiment. The cabin-driving control system includes: a cabin-driving controller 10, an audio sub-card 30, an inter-board connector 20, and at least one audio device 40. In addition, the control system may further include other more or fewer devices, such as an external power supply 50, a CAN network harness, etc.

[0042] Among them, the inter-board connector 20 is arranged between the cabin-driving controller 10 and the audio sub-card 30, and is used to connect the cabin-driving controller 10 and the audio sub-card 30.

[0043] The audio sub-card (Audio sub-card) 30 is a small expansion card in the sound card configuration, and is used to provide additional audio input and output functions. It usually has an independent audio processing chip and interface, and can achieve higher-quality audio input and output. The motherboard is the main sound card device, which has basic audio input and output functions, and is connected to the expansion slot (such as PCI or PCIe slot) on the computer motherboard, and communicates with the computer operating system through the driver.

[0044] Furthermore, the audio sub-card 30 has the ability to expand audio input and output. Specifically, the audio sub-card 30 enables users to connect more audio devices to meet higher-level audio processing requirements by providing additional audio input and output interfaces (such as analog input, analog output, digital input, digital output, etc.).

[0045] In addition, in this embodiment, the audio sub-card 30 also supports multi-channel audio, such as 5.1 channels or 7.1 channels, enabling users to enjoy a more stereo and realistic sound effect experience.

[0046] Among them, the cabin-driving controller 10 is used to generate audio signals and vehicle control signals, and output the audio signals and vehicle control signals to the inter-board connector 20.

[0047] Furthermore, as Figure 2 shown, the cabin-driving controller 10 includes a cockpit chip, such as a cockpit SOC 110 and a microprocessor MCU 120. And the cockpit SOC 110 and the microprocessor MCU 120 are respectively connected to the inter-board connector 20. The cockpit SOC 110 is used to generate and output audio signals to the inter-board connector 20, and the microprocessor MCU 120 is used to generate and output vehicle control signals to the inter-board connector 20.

[0048] The inter-board connector 20 is used to receive audio signals and vehicle control signals, and transmit the audio signals and vehicle control signals to the audio sub-card 30.

[0049] Specifically, the inter-board connector 20 is also called a board-to-board connector or an inter-board connection device, and is a device used to connect two or more printed circuit boards (PCBs) to achieve circuit transmission and connection. The inter-board connector 20 can be applied to various electronic devices, such as computers, communication equipment, industrial control equipment, etc., and is applied to the cabin control system in this embodiment.

[0050] The inter-board connector 20 has the following features:

[0051] First, strong transmission capability: inter-board connectors can efficiently transmit various signals, including data, audio, video and control signals, as well as power, ensuring smooth communication and stable power supply between various components inside electronic equipment.

[0052] Second, small size: With the trend of miniaturization and integration of electronic equipment, inter-board connectors are also developing in a more compact and lightweight direction to adapt to limited space requirements.

[0053] Third, easy installation: Inter-board connectors are usually designed to be easy to install and disassemble, making it convenient for users to replace or adjust them during maintenance and upgrades.

[0054] Fourth, reliability and durability: Inter-board connectors are usually designed as durable and reliable structures that can withstand vibrations, temperature changes and mechanical stresses that may occur during the normal operation of electronic equipment, ensuring the stability and durability of the connection.

[0055] The audio daughter card 30 includes an audio DSP module 310 and at least one amplifier 320 . Figure 2 5 AMPs (amplifiers) are shown, each of which is connected to an audio device 40. Specifically, the audio DSP module 310 includes a signal input terminal and a signal output terminal, and the number of the signal input terminal and the signal output terminal can be one or more, which is set according to actual conditions.

[0056] Optionally, the inter-board connector 20 is a B2B connector (Board-to-Board Connector).

[0057] Furthermore, the signal input end is used to connect to the inter-board connector 20 , and the signal output end is used to connect to at least one amplifier AMP 320 , each amplifier being connected to an audio device 40 .

[0058] The audio DSP module 310 is used to receive audio signals and vehicle control signals sent by the inter-board connector 20 and transmit them to at least one amplifier 320 . Each amplifier is used to send audio signals to the audio device 40 connected thereto.

[0059] Based on the aboveFigure 2 In the architecture, the signal transmission process includes: The cockpit SOC 110 in the cockpit-driving controller 10 generates an audio signal, the MCU 120 generates a vehicle control signal, and the cockpit SOC 110 and the MCU 120 respectively send the audio signal and the vehicle control signal directly to the multi-channel Audio sub-card 30 through the inter-board connector 20. After receiving the signals, the audio DSP module 310 in the Audio sub-card 30 parses the audio signal and the vehicle control signal, and sends at least one audio signal to the corresponding AMP, so that each AMP transmits the audio signal to the audio device connected thereto after receiving the audio signal.

[0060] The cockpit-driving control system provided by the utility model patent replaces the original A2B connector with an inter-board connector, that is, a B2B connector, for connecting the cockpit-driving controller and the Audio sub-card. Since the A2B signal is no longer transmitted between the cockpit-driving controller and the Audio sub-card, there is no need to set an A2B module and an MCU on the Audio sub-card. Instead, it can directly transmit through the DSP signal, eliminating modules such as the A2B module and the MCU, avoiding the problem of excessive single-board area caused by integrating a multi-channel power amplifier system, and at the same time solving the problem of excessive cost caused by the dependence of the PCB cost on the complex cockpit-driving system.

[0061] In addition, through the low-speed B2B connector, the cost of the transmission modules (wiring harness, A2B transceiver) required for the traditional power amplifier system to be pulled away from the cockpit system can also be saved. By integrating the cockpit-driving controller and the power amplifier system, the MCUs, communication modules, heat dissipation modules, etc. of the cockpit and the power amplifier can be combined, thereby reducing the complexity of the overall system and bringing about a reduction in the vehicle cost.

[0062] In a possible implementation, as Figure 2 shown, the cockpit-driving controller 10 further includes a CAN bus communication module 140, and the CAN bus communication module 140 is connected to the CAN network, such as connecting to the CAN grid wiring harness. The signal flow is that the microprocessor MCU120 transmits another generated control signal to the CAN grid wiring harness through the CAN bus communication module 140.

[0063] In addition, in some possible implementations, the cockpit-driving control system further includes an external power supply 50. The cockpit-driving controller 10 further includes a first power module 130, and the audio sub-card 30 further includes a second power module 330 and a boost power supply circuit 340. The external power supply 50 is connected to the second power module 330 for supplying power to the audio sub-card 30, and the boost power supply circuit 340 is connected to the second power module 330 for boosting the second power module 330.

[0064] The first power supply module 130 and the second power supply module 330 are respectively connected to an external power supply. The external power supply is used to supply power to the cabin driving controller 10 through the first power supply module 130 and supply power to the audio sub-card 30 through the second power supply module 330.

[0065] It should be understood that the power supply connected to the first power supply module 130 and the external power supply connected to the second power supply module 330 can be the same power supply or different power supplies, and this embodiment does not limit this.

[0066] In some other possible implementation manners, a heat dissipation structure is further included in the cabin driving control system, such as Figure 3 As shown, the heat dissipation structure is respectively connected to the cabin driving controller 10 and the audio sub-card 30, and is located between the cabin driving controller 10 and the audio sub-card 30, and is used to dissipate heat from the cabin driving controller 10 and the audio sub-card 30.

[0067] Furthermore, the heat dissipation structure includes: pipes, valves, heat sinks, and a controller. In addition, other components are also included in this heat dissipation structure, such as connectors, temperature sensors, etc.

[0068] Among them, the pipes: are respectively connected to the cabin driving controller 10 and the audio sub-card 30, Figure 3 Among them, there is a gap between the cabin driving controller 10 and the audio sub-card 30, and a board-to-board connector 20 is installed in the middle, Figure 3 which is not shown in the figure. The heat dissipation structure is installed between the gaps.

[0069] Figure 3 Among them, the lower and upper arrows indicate the water inlet and outlet of the pipe. The working fluid enters at the water inlet, flows through the pipe, and exits from the water outlet. The working fluid has high heat conduction performance; such as water-cooled heat dissipation, etc. The shape of the pipe matches that of the cabin driving controller 10 and the audio sub-card 30. For example, the pipe can be a curved pipe surrounding the cabin driving controller 10 and the audio sub-card 30.

[0070] In addition, the pipe material can be copper, aluminum, etc. The shape of the pipe body can be straight, curved, spiral, or corrugated to increase the surface area and heat exchange area and improve the heat dissipation efficiency.

[0071] A valve is provided on the pipe. The valve is connected to the controller and is controlled by the controller to open and close.

[0072] The heat sink: is fixedly installed on the pipe and is used to increase the heat dissipation area. The heat sink can be a fin. The heat sink or fin is tightly fixed on the pipe body to improve the heat dissipation efficiency by increasing the heat dissipation area. The heat sink / fin is usually made of aluminum or copper and has excellent thermal conductivity and mechanical strength.

[0073] Optionally, connectors may be included for connecting pipes, cockpit controllers, and audio daughter cards, such as flanges, joints, etc. These connectors need to ensure the tightness and smooth flow of the fluid.

[0074] Controller: connected to the valve and heat sink, used to control the flow or stillness of the fluid in the pipeline by opening and closing the valve, and to control the heat dissipation of the heat sink. Specifically, the controller can realize automatic adjustment and control of the heat dissipation pipeline through sensors, actuators, and control algorithms. For example, when the temperature of the system is higher than the preset temperature detected by the temperature sensor, the valve is controlled to open and the fluid is pressurized. The pressurization control can be achieved through the pump to speed up the flow of the fluid, improve the heat dissipation efficiency, and accelerate the cooling. If the detected temperature meets the preset temperature, the valve can be controlled to close, so that the fluid stops flowing and remains static, and the system is not cooled at this time.

[0075] Specifically, the controller can adjust the operating status of the heat dissipation pipeline in real time according to factors such as ambient temperature and heat dissipation requirements to achieve energy saving and high efficiency.

[0076] Optionally, the controller may be a control circuit or a control module installed inside the heat dissipation structure.

[0077] It should be noted that in this embodiment Figure 3 Only one line is used to indicate the position of the heat dissipation structure, and the specific structures of the pipes, valves, heat sinks and controllers are not shown. The structures and connection relationships of these components can be flexibly set according to actual needs. This embodiment does not impose specific restrictions on the structure, size, connection relationship, etc. of these components / devices.

[0078] The utility model realizes the integrated multi-channel power amplifier solution of the cockpit system, utilizes the design conditions of the cockpit system to optimize the space and heat dissipation problems of the existing multi-channel power amplifier system, and realizes cost reduction and weight reduction of the whole vehicle system through the deep integration of the cockpit system and the power amplifier system.

[0079] It should be noted that with the further evolution of the cockpit system, the next generation of cockpit processing chips will be more integrated, and most solutions can integrate high-performance DSP modules. Subsequently, the built-in DSP of the cockpit SOC can be used instead of the external DSP to further reduce the cost of the power amplifier system.

[0080] In addition, since the cockpit controller is usually placed at the front of the vehicle, after the power amplifier system is integrated, the speaker wires are moved from the rear of the vehicle to the front, and the overall length of the wiring harness is reduced, thereby saving the cost and weight of the wiring harness.

[0081] In addition, the present invention also provides a vehicle, such as Figure 4 As shown, the vehicle at least includes a cabin control system, the structure of which is similar to the above Figure 2 orFigure 3 The system structures shown are the same and are used to solve the problem of excessively high costs caused by the dependence of PCB costs on complex cabin driving systems. At the same time, it also avoids the problem of excessive single-board area caused by integrating multi-channel power amplifier systems.

[0082] Specifically, for the structure in this cabin driving control system and the functions of each component / device, reference can be made to the description in the foregoing embodiments, and details are not repeated here.

[0083] The above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, rather than to limit them; although the embodiments of the present invention have been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; 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 invention.
