[0043] In some embodiments, such as Figure 1 As shown, a controller includes:
[0044] First functional module; and
[0045] The second functional module is used to send control commands to the first functional module so that the first functional module can work according to the control commands.
[0046] The controller provided in this embodiment includes a first functional module and a second functional module, and the second functional module sends control commands to the first functional module to control its operation, thereby reducing communication latency and improving the response speed of the corresponding functions.
[0047] To improve response speed, in some embodiments, the first functional module and the second functional module communicate by sharing data.
[0048] In other words, by sharing data, the two functional modules in the controller can effectively improve the data transmission speed between them and thus improve the response speed.
[0049] To improve response speed, in some embodiments, the second functional module sends control instructions to the first functional module via memory.
[0050] That is, in some embodiments, the second functional module can store control instructions in memory, and the first functional module can read the control instructions from memory to perform control work, thereby improving the response speed.
[0051] To facilitate improved response speed, in some embodiments, the first and second functional modules are configured as a system-on-a-chip or a microcontroller.
[0052] That is, in some embodiments, the first functional module and the second functional module can be integrated into a system on chip (SOC) or a microcontroller unit (MCU), so that they can communicate without using CAN communication, thereby effectively improving the response speed of the corresponding functions.
[0053] The first functional module can be a module that implements various suitable functions. In order to control seat belt pretensioning, in some embodiments, the first functional module is used to implement the seat belt pretensioning control function.
[0054] In some embodiments, the first functional module is used to control the seat belt pretensioner actuator to operate according to control instructions. That is, the first functional module can implement the seat belt pretensioning control function to control the seat belt pretensioner actuator to pretension the seat belt.
[0055] The second functional module can be a module that implements various suitable functions. In order to control seat belt pretensioning, in some embodiments, the second functional module is used to implement at least one of the following control functions: tire blowout stability control function, anti-lock braking function, and collision warning function.
[0056] That is, the second functional module can realize one or more of the functions of tire blowout stability control, anti-lock braking, and collision warning, and can send seat belt pretensioning control commands to the first functional module (which realizes seat belt pretensioning control) to control seat belt pretensioning.
[0057] The second functional module can be a module that implements various suitable functions. In order to control the seat belt pretensioning, in some embodiments, the second functional module is used to send control commands to the first functional module in at least one of the following situations:
[0058] When a vehicle experiences a tire blowout;
[0059] When a vehicle experiences brake lock-up;
[0060] When a vehicle is about to collide.
[0061] That is, the second functional module can realize one or more of the following functions: tire blowout stability control, anti-lock braking, and collision warning. When a tire blowout occurs, when the vehicle brakes to lock, or when a collision is about to occur, the second functional module can send control commands to the first functional module (which realizes the seat belt pretensioning control function) to control the seat belt pretensioning.
[0062] In some embodiments, the controller may be configured as a domain controller.
[0063] The controller provided in this embodiment includes a first functional module and a second functional module, and the second functional module sends control commands to the first functional module to control its operation, thereby reducing communication latency and improving the response speed of the corresponding functions.
[0064] The following explanation uses seatbelt pretensioners and tire blowout stability control systems as examples. Figure 2 As shown, the integrated domain controller system includes the following modules:
[0065] Domain Controller: As the control core of the system, it is responsible for receiving tire pressure signals from the tire pressure sensor and sending control commands to the seat belt pretensioner. It integrates the tire blowout stability control system and the seat belt pretensioner control system.
[0066] Tire blowout stability control system: Used to monitor the tire status in real time, detect the occurrence of a tire blowout, and when a blowout occurs, determine the severity of the blowout and issue control commands to the brakes, steering, seat belts, instruments, etc., to achieve stable stopping after a tire blowout.
[0067] Seatbelt pretensioning control system: controls the seatbelt pretensioning actuator to adjust the pretensioning force and timing of the seatbelt in real time to ensure the safety of occupants.
[0068] Seatbelt pretensioner actuator: Receives seatbelt tightening commands from the seatbelt pretensioning control system and drives the motor.
[0069] Battery power supply: Power supply equipment for domain controllers and seat belt pretensioners.
[0070] When the tire blowout stability control system detects a tire blowout signal, it directly transmits the signal to the seatbelt pretensioning control system via the MCU's internal bus. Upon receiving the signal, the seatbelt pretensioning control system immediately sends a seatbelt tightening command to the seatbelt pretensioning module, achieving a rapid response.
[0071] Specific steps are as follows: Figure 3 The workflow diagram is shown below:
[0072] Step 1: The domain controller receives the tire pressure signal from the tire pressure sensor.
[0073] Step 2: The tire blowout stability control system determines whether a tire blowout has occurred. If yes, it proceeds to the next step; otherwise, it returns to continue the determination process.
[0074] Step 3: The seat belt pretensioner receives the pretensioning command from the tire blowout stability control system and tightens the seat belt to protect the driver.
[0075] Step 4: The seat belt pretensioning motor executes the seat belt tightening command.
[0076] In some embodiments, this disclosure has the following beneficial effects:
[0077] High communication speed: By integrating a domain controller, the latency of traditional CAN bus communication is eliminated, significantly improving the system's response speed.
[0078] High control precision: Direct internal communication avoids signal interference and transmission errors, improving the control precision of the system.
[0079] High system reliability: Integrated design reduces system complexity, lowers the failure rate, and improves the overall system reliability.
[0080] This disclosure also provides a vehicle system including a controller as provided in any of the above embodiments.
[0081] In some embodiments, the vehicle system further includes:
[0082] Seat belt pretensioner, which is connected to the first functional module.
[0083] That is, after receiving the control command, the first functional module controls the seat belt pretensioner to pretension the seat belt, thereby realizing the seat belt pretensioning control function and improving safety.
[0084] In some embodiments, the vehicle system further includes at least one of the following devices:
[0085] Tire pressure sensor;
[0086] Wheel speed sensor;
[0087] Camera;
[0088] radar.
[0089] That is, the second functional module can determine a tire blowout by detecting the tire pressure signal through the tire pressure sensor; it can realize anti-lock braking control through the wheel speed sensor; and it can realize collision warning function through the camera and / or radar. Thus, it can send control commands to the first functional module to realize the seat belt pretensioning control function.
