Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle area control device, electronic and electrical system, and vehicle. Background Technology

[0002] With the continuous development of automotive electrification, intelligentization, connectivity, and sharing (the "new four modernizations"), automotive functions are becoming increasingly rich and user-friendly, leading to a surge in the number of electronic components and increasingly complex interaction logic between them. Therefore, automotive electronic and electrical architecture must be able to support the development of these "new four modernizations." The new electronic and electrical architecture must possess high communication bandwidth, high computing power, and high network security, and support over-the-air (OTA) software upgrades. As these "new four modernizations" continue to evolve, automotive electronic and electrical architecture will also undergo continuous innovation, with a centralized electronic and electrical architecture becoming the mainstream development direction for future automotive electronic and electrical architectures.

Detailed Implementation

[0027] With the continuous development of vehicle electrification, intelligence, connectivity, and sharing (the "new four modernizations"), the following main problems exist: First, the number of sensors and actuators in vehicles is growing rapidly, and the direct hard-wired interaction between sensors, actuators, and the central computing unit leads to overly complex vehicle wiring harnesses; second, the central computing unit is responsible for the signal acquisition of the vehicle's sensors and the on-demand control of actuators, and the complex acquisition and drive circuits result in a very large central computing unit, which is not conducive to the overall vehicle layout; third, the number of vehicle interaction signals has increased significantly, and the interaction frequency has risen sharply, posing a huge challenge to the design of the communication architecture. Therefore, OEMs have moved all vehicle logic algorithms to the central computing unit. Sensors need to perform simple processing of vehicle status information and then send it to the central computing unit for in-depth decision-making via CAN bus (Controller Area Network), CANFD bus (CAN with Flexible Data rate), or fiber optic communication. Finally, the decision results are sent to the actuators via CAN bus, CANFD bus, or fiber optic communication. Therefore, under this new electronic and electrical architecture, sensors and actuators are required to have simple signal processing capabilities. These new sensors and actuators are called smart sensors and smart actuators. The emergence of these smart sensors and smart actuators simplifies the vehicle wiring harness to power lines, ground lines, CAN / CANFD lines, and fiber optics. To further reduce overall vehicle wiring harness costs, the vehicle is divided into several zones. Intelligent actuators and sensors in each zone are connected to the zone control unit via CAN bus / CANFD bus / fiber optic cable. Each zone control unit interacts with the central computing unit via fiber optic cable. This "central computing + zone control" electronic and electrical architecture not only improves the overall vehicle communication speed but also significantly reduces wiring harness costs. Furthermore, fiber optic communication offers high speed, low power consumption, and energy efficiency. It also effectively avoids interference from complex electromagnetic environments inside and outside the vehicle, thus effectively protecting system data security. Therefore, fiber optic communication has become an inevitable requirement for the continuous development of the four new trends in automotive technology.

[0028] Based on the requirements of the above-mentioned new centralized electronic and electrical architecture, the area control device not only needs to be responsible for the communication between the intelligent sensors, intelligent actuators and the central computing unit in its area, but also needs to supply power to the intelligent actuators and intelligent sensors in its area.

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0030] like Figure 1 According to an embodiment of this application, the area control device 10 includes a first connection terminal 131 and a plurality of power supply terminals. The first connection terminal 131 is used to connect to a power source, and the power supply terminals are used to connect to electronic devices 40. The first connection terminal 131 is electrically connected to the power supply terminals to supply power to the electronic devices 40. The first connection terminal 131 can be directly or indirectly connected to a power source, which can be a storage battery or a lithium battery, etc., and is responsible for supplying power to each module in the area control device 10. The electrical connection between the first connection terminal 131 and the power supply terminals includes, but is not limited to: the first connection terminal 131 being directly or electrically connected to the power supply terminals through wires, etc.; the first connection terminal 131 being indirectly electrically connected to the power supply terminals through other components, etc.

[0031] According to the embodiment of this application, the area control device 10 can supply power to the corresponding electronic device 40, which can facilitate vehicle wiring and provide power supply stability.

[0032] Additionally, the area control unit 10 may also include a communication module for communicating with other electronic devices in the vehicle. The area control unit has communication and power distribution functions, enabling communication and power supply to relevant electronic components.

[0033] The connection between the first connection terminal 131 and the power supply terminal in this application may include, but is not limited to, the following embodiments.

[0034] Implementation method one, such as Figure 1The area control device 10 also includes a switching element 14 and several power supply terminals, including a first power supply terminal 121. The switching element 14 is connected between the first connection terminal 131 and the first power supply terminal 121. That is, the first end of the switching element 14 is connected to the first connection terminal 131, and the second end of the switching element 14 is connected to the first power supply terminal 121. The switching element 14 can control the on / off state between the first connection terminal 131 and the first power supply terminal 121. When the switching element 14 is closed, current is introduced into the first connection terminal 131 and sent to the first power supply terminal 121 after passing through the switching element 14, and then to the electronic device 40 connected to the first power supply terminal 121. The first power supply terminal 121 can be connected to the vehicle's IG power resources. That is, the electronic device 40 connected to the first power supply terminal 121 can be a component that only supplies power after the vehicle is started. Of course, the first power supply terminal 121 can also be connected to the vehicle's constant power resources, that is, a component that can supply power even when the vehicle is not started.

[0035] The area control device 10 also includes a power management module 15, which is electrically connected to the switching element 14 and the first connection terminal 131. The power management module 15 can provide control signals to the switching element 14 to control its operating state, such as opening and closing. The power management module 15 facilitates control of the switching element 14's state. By placing the power management module 15 in the area control device 10, control signals can quickly reach the corresponding switching element 14, thereby improving the stability of control filtering. Of course, the power management module 15 can also be placed in components such as the central computing unit 30. This application mainly uses the example of placing the power management module 15 in the area control device 10 for illustration, which is not intended to limit the scope of protection of this application.

[0036] Furthermore, the power management module 15 in this application can communicate with other control devices. For example, the power management module 15 can be configured to communicate with the central computing unit 30. The power management module 15 can communicate with other components wirelessly, such as via Wi-Fi or Bluetooth. Alternatively, the power management module 15 can also communicate with other components via a wired connection.

[0037] The power management module 15 in this application is mainly responsible for controlling the opening and closing of the switching element 14 (e.g., MOSFET) according to the command of the central computing unit 30, so as to realize the power management of the electronic device 40 in this area. Specifically, the central computing unit 30 sends the power management requirements of each area to the area control device 10 through the optical signal, and then sends it to the photoelectric conversion module 17 through the beam splitter 16 in the area control device 10, and then sends it to the power management module 15 through the photoelectric conversion module 17. This method can realize the power supply of the vehicle's electrical appliances on demand, and only supply power when there is a working demand, so as to realize the ultimate management of the static power consumption of the whole vehicle.

[0038] In addition, the area control device 10 may also include a communication module, which communicates with the power management module 15 and is electrically connected to the first connection terminal 131. The communication module can be a wired communication method, such as using a CAN bus or a CANFD bus; or it can be a wireless communication method, such as wireless network communication or Bluetooth communication.

[0039] In addition, such as Figure 2 The area control device 10 may further include a second connection terminal 132. The first connection terminal 131 and the second connection terminal 132 are used to connect a fuse element, wherein the fuse element can be detachably or non-detachably connected to the first connection terminal 131 and the second connection terminal 132, and wherein a switching element 14 can be connected between the second connection terminal 132 and the first power supply terminal 121. The fuse element can be used to improve the stability of the area control device 10 and facilitate rapid maintenance of the area control device 10.

[0040] In the second embodiment, the area control device 10 further includes a third connection terminal. The first connection terminal 131 and the third connection terminal are used to connect a fuse element. A plurality of power supply terminals include a second power supply terminal 122, which is electrically connected to the third connection terminal. That is, the second power supply terminal 122 is connected to the first connection terminal 131 via a fuse element. The second power supply terminal 122 can be connected to a constant power source in the vehicle, such as a component that can supply power when the vehicle is not started.

[0041] In the third embodiment, the area control device 10 may include a second connection terminal 132 and a third connection terminal. The first connection terminal 131 and the second connection terminal 132 are used to connect a fuse element. The first connection terminal 131 and the third connection terminal are used to connect a fuse element. A switch element 14 may be connected between the second connection terminal 132 and the first power supply terminal 121. The second power supply terminal 122 is electrically connected to the third connection terminal.

[0042] The area control device 10 in this application can have power distribution function and signal transmission function, so as to send the signal collected by the electronic device 40 to the central computing unit 30, or to send the control mode of the central computing unit 30 to the electronic device 40.

[0043] like Figure 1 In some embodiments of this application, other electronic devices of the vehicle may include at least one of a central computing unit, an actuator, and a sensor.

[0044] The area control device 10 may further include several downstream communication terminals for connecting to electronic devices 40 and communicating with a communication module. Communication with the electronic devices 40 is achieved through these downstream communication terminals. Specifically, when the central computing unit 30 or other components transmit a signal associated with a particular electronic device 40 to the area control device 10, the signal can be received by the communication module, transmitted to the corresponding downstream communication terminal, and ultimately sent to the corresponding electronic device 40. When an electronic device 40 needs to upload information, it can transmit the information to the downstream communication terminal, which then sends it to the communication module, where the information is uploaded.

[0045] Additionally, the area control device 10 may include an upstream communication terminal for connecting to the central computing unit 30 and communicating with the communication module. Communication with the central computing unit 30 can be achieved through the upstream communication terminal. Specifically, when the central computing unit 30 or other components transmit signals to the area control device 10, the signals can be sent to the communication module via the upstream communication terminal, then transmitted to the corresponding downstream communication terminal, and finally sent to the corresponding electronic device 40. When an electronic device 40 needs to upload information, it can transmit the information to the downstream communication terminal, then to the communication module, and finally upload the information via the upstream communication terminal.

[0047] This application primarily uses the example of a communication module configured to communicate wiredly with both the central computing unit 30 and the electronic device 40, but this is not a limitation on the scope of protection of this application. Optionally, the communication module can be configured to communicate optically and / or electrically with both the central computing unit 30 and the electronic device 40; and / or, the communication module can be configured to communicate optically and / or electrically with both the electronic device 40.

[0060] In addition, the communication module also includes a beam splitter 16, which communicates optically with the photoelectric conversion module 17, and is configured to communicate optically with another part of the electronic devices 40 and the central computing unit 30.

[0061] In conjunction with the foregoing, the upstream communication terminal is an optical signal terminal, and the plurality of downstream communication terminals include a first communication terminal, which is an electrical signal terminal; the plurality of downstream communication terminals also include a second communication terminal, which is an optical signal terminal, and the communication module includes a photoelectric conversion module 17 and a beam splitter 16.

[0065] In conjunction with the foregoing embodiments, during the early stages of vehicle development, based on the vehicle's power distribution and communication requirements, the regional control device 10 can be designed as several standardized platforms. This satisfies the vehicle model requirements while reducing the number of product states for the regional control device 10. The aforementioned regional control device 10 should possess good scalability.

Additionally, the electronic and electrical system includes actuators and / or sensors connected to the communication module. The electronic and electrical system may comprise a central computing unit, actuators, and sensors. The sensors are responsible for collecting various operating condition information of the vehicle, including but not limited to vehicle speed, various medium temperatures, engine operating conditions, internal and external environmental conditions, operating conditions of key components, and driver intentions. These sensors convert various status information into electrical signals and transmit them to the central computing unit.
