Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more particularly to a vehicle control system and a vehicle. Background Technology

[0002] Currently, vehicles typically unlock their security systems via remote key recognition. While some vehicles are equipped with keyless entry systems, users still need to carry the smart key to unlock them. If a user forgets to bring the key or loses the key, they cannot use the vehicle. Therefore, existing vehicles usually have facial recognition devices installed on the B-pillar between the front and rear doors for vehicle unlocking.

[0003] Typically, facial recognition devices are connected to a separate B-pillar controller. The B-pillar controller processes and analyzes the acquired data, and then interacts with other domain controllers in the vehicle via a gateway to control the vehicle's door locks. This results in a complex vehicle topology, numerous components and wiring, high hardware costs, and a significant development workload. Utility Model Content

[0026] Figure 4 This is a schematic diagram of another vehicle control system provided in an embodiment of the present disclosure. Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0029] Currently, vehicles can be equipped with facial recognition devices installed at the B-pillar between the front and rear doors for unlocking. Typically, the facial recognition device is connected to a separate B-pillar controller. This controller processes and analyzes the acquired data, then interacts with other domain controllers within the vehicle via a gateway to control the door locks. This results in a complex vehicle topology, numerous components and wiring, high hardware costs, and a significant development workload.

[0030] To address the aforementioned deficiencies, this disclosure provides a vehicle control system. Figure 1 This is a schematic diagram of a vehicle control system provided in this disclosure. The vehicle control system includes: a cockpit domain controller 10, a sensor module 20, and a display module 30. Both the sensor module 20 and the display module 30 are connected to the cockpit domain controller 10 via wiring harnesses; the sensor module 20 and the display module 30 are disposed on the outside of the vehicle housing.

[0031] For example, the vehicle includes a sensor module 20 and a display module 30, both of which are located on the outer side of the vehicle's housing. The sensor module 20 is used to acquire external parameters of the vehicle or parameters provided by the user. For instance, the sensor module 20 may include a fingerprint sensor. When a user needs to enter the vehicle, the sensor module 20 is positioned on the outer side of the vehicle housing, and the user can unlock or lock the doors by inputting their fingerprint. This eliminates the need for a key, avoiding situations where the key is forgotten or lost. Alternatively, the sensor module 20 may include an image sensor, allowing the user to unlock or lock the doors using facial recognition. The display module 30 can then display the facial data collected by the image sensor, allowing the user to adjust the angle between their face and the image sensor to quickly acquire the facial data for subsequent door unlocking or locking operations.

[0032] In this embodiment, both the sensor module 20 and the display module 30 are connected to the cockpit domain controller 10 via wiring harnesses. The cockpit domain controller 10 is the domain controller in the vehicle. The cockpit domain controller integrates components such as the head-up display, instrument panel, and navigation via Ethernet, MOST (Media Oriented System Transport), or CAN (Controller Area Network), optimizing functions such as intelligent driving, vehicle connectivity, and infotainment. The system-on-a-chip (SoC) of the cockpit domain controller boasts powerful performance, with computing power reaching 200 KDMIPS or higher. Its image processing and AI (Artificial Intelligence) processing capabilities are significantly improved compared to a standalone controller, greatly enhancing display and recognition processing speed and improving user experience. Furthermore, the cockpit domain controller has larger memory and OTA (Over-The-Air) capabilities for continuous iteration, allowing for continuous optimization and iteration, thereby expanding functionality and optimizing the user experience.

[0033] Therefore, the sensor module 20 transmits the acquired parameters to the cockpit domain controller 10. The cockpit domain controller 10 processes the parameters. For example, the sensor module 20 transmits the acquired external facial data to the cockpit domain controller 10. Due to the powerful computing capabilities of the cockpit domain controller 10, it can quickly perform facial recognition processing. The cockpit domain controller 10 can also send the processed facial data to the display module 30 for display.

[0034] Unlike existing technologies, this disclosure eliminates the need for a separate controller to process parameters transmitted by the sensor module, allowing the vehicle's cockpit domain controller to perform the corresponding functions. This disclosure directly connects the sensor module and display module to the cockpit domain controller. Parameters collected by the sensors are transmitted to the cockpit domain controller for processing. The cockpit domain controller can also control the display module for display. This disclosure eliminates the need for a separate controller to process the data, reducing the number of hardware components and wiring harnesses, lowering costs, and reducing overall vehicle weight.

[0035] In some embodiments, Figure 2 This is a schematic diagram of another vehicle control system provided in an embodiment of the present disclosure, with reference to... Figure 2 The vehicle control system also includes a wireless communication module 40; the wireless communication module 40 is connected to the cockpit domain controller 10; the wireless communication module 40 is used to receive instruction information provided by the user through a smart terminal and transmit the instruction information to the cockpit domain controller 10.

[0036] For example, the wireless communication module 40 is connected to the cockpit domain controller 10 and can interact with the smart terminal (mobile phone) via a server (cloud). For instance, if a user needs to set up facial recognition unlocking or locking for the vehicle, they can pre-register facial data in the smart terminal. The mobile network data is sent to the wireless communication module 40 via the server, and then transmitted to the cockpit domain controller 10. The facial recognition algorithm stored inside the cockpit domain controller 10 extracts facial feature values ​​from the facial data and saves them. Subsequently, when the user performs facial recognition unlocking or locking operations via the sensor module 20, the cockpit domain controller 10 analyzes and processes the facial data acquired by the sensor module 20 and compares it with the pre-stored facial feature values ​​to determine whether the unlocking or locking requirements are met. The mobile network data can be a 4G network or a 5G network, meaning the wireless communication module can be a 4G module or a 5G module.

[0037] Alternatively, users can provide command information via a smart terminal. The wireless communication module 40 receives the command information and transmits it to the cockpit domain controller 10, thereby controlling the unlocking or locking of the vehicle doors. Specifically, the command information is facial data, such as facial recognition via a smart terminal. The smart terminal collects facial data and sends it to the wireless communication module 40 via a server, which in turn sends it to the cockpit domain controller 10. The cockpit domain controller 10 processes the facial data sent by the smart terminal and sends it to the display module 30 for display. This embodiment reuses the wiring harness channel between the cockpit domain controller and the wireless communication module 40, eliminating the need for a separate controller. This reduces the wiring harness connection between a separate controller and the wireless communication module, lowering design costs and complexity, while still meeting practical functional requirements.

[0038] In some embodiments, continue to refer to Figure 2 It also includes a body domain controller 60 and a gateway device 50; the body domain controller 60 is connected to the cockpit domain controller 10 through the gateway device 50.

[0039] For example, the vehicle control system also includes a body domain controller 60, which is connected to the cockpit domain controller 10 via a gateway device 50. The body domain controller 60 controls various body functions, including at least the control of headlights, door locks, windows, sunroof, windshield wipers, power tailgate, air conditioning, and antenna. Therefore, when facial recognition is used for unlocking or locking via sensor module 20, the cockpit domain controller 10 processes and compares the facial data and sends the recognition result to the body domain controller 60 via the gateway device 50. The body domain controller 60 then controls the door unlocking or locking. Furthermore, the body domain controller 60 can acquire vehicle status information, such as tire pressure and battery level, and can send this information to the cockpit domain controller 10 via the gateway device 50. The cockpit domain controller 10 then sends the vehicle status information to the display module 30, where it is displayed. Users can check the vehicle's status without getting into the car, avoiding the need to get out and inspect the vehicle after discovering a problem, thus improving the user experience.

[0040] In some embodiments, Figure 3 This is a schematic diagram of the structure of a vehicle provided in an embodiment of the present disclosure, with reference to... Figure 3 The sensor module 20 and the display module 30 are located in the B-pillar area of ​​the vehicle.

[0041] For example, the pillar between the front and rear doors of a vehicle is the B-pillar area. The sensor module 20 and display module 30 are positioned in this area to form a smart B-pillar structure. For instance, the sensor module 20 includes an image sensor, and the display module 30 can display the data acquired by the image sensor. The sensor module 20 and display module 30 enable facial recognition unlocking or locking of the vehicle. By placing them in the B-pillar area, when a user needs to unlock the door and enter the cockpit, facial recognition can be performed near the door without requiring significant movement. The display module 30 acquires facial data and transmits it to the cockpit domain controller 10 via a wiring harness. The cockpit domain controller 10 compares the acquired facial data with pre-stored facial feature values. If the comparison result matches the pre-stored facial feature values, the vehicle domain controller unlocks the door, allowing the user to directly enter the cockpit. Placing the sensor module and display module in the same area allows the user to adjust their facial angle during facial recognition, improving recognition speed.

[0042] In some optional embodiments, the sensor module and display module can also be located in other areas of the vehicle body, such as the A-pillar area, C-pillar area, or other locations, depending on actual needs. Alternatively, the sensor module and display module can be located in different areas, for example, the sensor module in the A-pillar area and the display module in the B-pillar area. Or, if the vehicle has an image sensor for detecting obstacles, this external image sensor can be reused as the sensor module for facial recognition unlocking or locking operations. It should be noted that the embodiments disclosed herein do not limit the specific locations of the sensor module and display module.

[0043] Optionally, the sensor module may include various types of sensors such as image sensors, fingerprint recognition sensors, and ultrasonic radar sensors to acquire external information. Therefore, the types of sensors included in the sensor module can be determined based on the type of information to be acquired. The display module may include an LCD (Liquid Crystal Display) for displaying information acquired by the sensor module or vehicle status information. The display module can also be a touch screen, which can both display functions and meet some user control needs. For example, a user can unlock or lock the doors by entering a password on the touch screen. The cockpit domain controller can store preset passwords. When a user enters a password, the cockpit domain controller compares the entered password with the preset password to unlock or lock the doors. It should be noted that this embodiment does not limit the type of display module; it can be set according to actual needs.

[0044] In some embodiments, Figure 4 This is a schematic diagram of another vehicle control system provided in an embodiment of the present disclosure, with reference to... Figure 4 The cockpit domain controller 10 includes a system-on-a-chip 11; the system-on-a-chip 11 is connected to the sensor module 20 and the display module 30 via wiring harnesses.

[0045] For example, the cockpit domain controller 10 includes a system-on-chip 11, such as a system-on-chip (SoC). The SoC of the cockpit domain controller 10 is used to receive data information transmitted by the sensor module 20, such as video information or image information. The SoC integrates an AI Core (artificial intelligence core) for image processing, which sends the processed data to the display module 30. In addition, the SoC also integrates an operating system for logic processing and HMI (Human Machine Interface) display functions.

[0046] In this embodiment, the system-on-chip 11 of the cockpit domain controller 10 is connected to the sensor module 20 and the display module 30 via wiring harnesses. The system-on-chip 11 of the cockpit domain controller 10 has high computing power and strong processing capabilities, eliminating the need for an additional controller to process the information acquired by the sensor module 20. Therefore, this reduces the use of hardware and wiring harnesses, lowering overall vehicle costs and weight, while also reducing software development costs and improving the processing speed of relevant data, thus enhancing the user experience.

[0047] In some embodiments, continue to refer to Figure 4 The sensor module 20 includes an image acquisition unit; the cockpit domain controller 10 includes a deserializer 12; and the system-on-a-chip 11 is connected to the image acquisition unit through the deserializer 12.

[0048] For example, the sensor module 20 includes an image acquisition unit, which can be a TOF (Time of Flight) camera. A TOF camera obtains the depth (distance) information of the entire image by continuously sending light pulses to a target, receiving the light returning from the object, and detecting the time of flight (round trip) of the light pulses. Compared to ordinary cameras, TOF cameras are 3D cameras with depth perception capabilities, capable of detecting 3D information of people outside the vehicle, and suitable for imaging in low-light environments. They are mainly used for motion detection, facial recognition, and other applications, improving the security of facial recognition unlocking. In some scenarios, if ordinary cameras are used for facial recognition, there is a possibility of successfully unlocking car doors with photos, posing security risks. Using a TOF camera as the image acquisition unit allows the acquisition of the user's depth image, which is then converted into a parallel format by a deserializer 12 and sent to the system-on-a-chip 11 for processing. The system-on-a-chip 11 compares the depth image to determine if it meets the unlocking requirements. To prevent people from using photos to unlock car doors and ensure the safety of vehicles and people.

[0049] Optionally, in some scenarios, existing cameras connected to the cockpit domain controller on the outside of the vehicle can be used to reduce development costs and hardware usage. In addition to the image acquisition unit, the sensor module 20 may also include other types of acquisition units, such as other fingerprint recognition units, ultrasonic detection units, etc.

[0050] In some embodiments, continue to refer to Figure 4 The cockpit domain controller 10 includes a serializer 13; the system-on-a-chip 11 is connected to the display module 30 via the serializer 13.

[0051] For example, the system-on-chip 11 is also connected to the display module 30 via a serializer 13, and the system-on-chip 11 sends the processed data to the display module 30. The display module 30 can be an LCD. For instance, in a function that unlocks or locks the car via facial recognition, the LCD can display facial information acquired by the sensor module 20, allowing the user to adjust the angle between their face and the image sensor during the unlocking process, enabling the image sensor to quickly acquire facial data for subsequent door unlocking or locking operations.

[0052] Optionally, the LCD can display both image and video information, depending on the sensor type. In addition, the LCD can also display vehicle status information provided by the cockpit domain controller 10, such as tire pressure, battery level, whether doors are closed, and whether there are any leftover items inside the vehicle. It can also display the vehicle's human-machine interface. Specific settings can be configured according to actual needs; this embodiment does not limit the types of information displayed by the display module 30.

[0053] In some embodiments, continue to refer to Figure 4 The cockpit domain controller 10 also includes a control chip 14 and a CAN transceiver 15; the control chip 14 is connected to the system-on-a-chip 11 and the CAN transceiver 15 respectively.

[0054] For example, the cockpit domain controller 10 includes a control chip 14, such as an MCU (Micro Controller Unit). The MCU is also electrically connected to a power supply module; therefore, the MCU controls the power supply module to power the system-on-a-chip 11, enabling the system-on-a-chip 11 to perform relevant processing and calculation operations. The control chip 14 is also connected to a CAN transceiver 15. When the system-on-a-chip 11 needs to interact with other controllers, the MCU transmits the interaction information to the CAN transceiver, which then forwards the information. Similarly, when other controllers transmit data to the system-on-a-chip 11 via the CAN bus, the data is received by the CAN transceiver and forwarded to the MCU, which then transmits it to the system-on-a-chip 11.

[0055] Optionally, the power supply module can be connected to the vehicle's power supply. The control chip can control the power supply module to perform voltage conversion, supplying power to various chips in the cockpit domain controller and meeting the operating voltage requirements of different chips.

[0056] In some embodiments, continue to refer to Figure 4 The cockpit domain controller 10 also includes a storage unit 16; the storage unit 16 is connected to the system-on-a-chip 11; the storage unit 16 is used to store the information collected by the sensor module 20 and the processing information of the system-on-a-chip 11.

[0057] Storage unit 16 is connected to system-on-a-chip 11. Storage unit 16 includes DDR (Double Data Rate SDRAM) and UFS (Universal Flash Storage). The cockpit domain controller 10 needs to store software code and recognition algorithms, so it stores them in storage unit 16. The information collected by the sensor module 20 can also be stored in this unit so that the system-on-a-chip 11 can perform calculations and processing on the relevant information. The processed information can also be stored in storage unit 16 for later retrieval.

[0058] Optional, continue to refer to Figure 4 The cockpit domain controller 10 also includes circuit components such as a USB interface, an Ethernet gateway (ETHSwitch), an Ethernet interface chip (ETH PHY), a DSP (Digital Signal Processor), an AMP (Amplifier), a tuner, a BT&WIFI module, and a GNSS module (Global Navigation Satellite System Module). Specific configurations can be tailored to actual needs, and corresponding functions can be executed. This disclosure does not impose specific limitations on these embodiments, but is merely illustrative.

[0059] Based on the above structure, for vehicle facial recognition unlocking, the sensor module is connected to the system-on-a-chip (SoC) of the cockpit domain controller via a deserializer. The operating system, facial recognition algorithm, and software code are all integrated into the SoC and storage unit of the cockpit domain controller. The image or video processed by the SoC is directly output to the display module for display via a serializer. The remaining structure can reuse the internal circuitry of the cockpit domain controller, eliminating the need for a separate controller for facial recognition unlocking and other operations. This significantly reduces the design and use of hardware and wiring harnesses, and also reduces software development. Furthermore, reusing the cockpit domain controller improves processing speed and enhances vehicle performance and scalability.

[0060] This disclosure also provides a vehicle including the vehicle control system described in any of the above embodiments. Since this disclosure includes the vehicle control system described in any of the above embodiments, it has the same or corresponding beneficial effects as the vehicle control systems described in the above embodiments.

[0061] It should be noted that the vehicle provided in this embodiment may also include other circuits and devices for supporting its normal operation, and this embodiment does not impose any special limitations on this.

[0062] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
