[0046] Embodiment 3

[0047] Figure 3 This is a schematic diagram of the structure of the power input circuit provided in the embodiment of the present application. Figure 3As shown, two power inputs (first battery and second battery) are processed by the first power input circuit AA and the second power input circuit AB respectively, and then a power supply a is synthesized to supply power to the system. The embodiment of the present application is a dual-power redundant power supply and realizes isolation of the two power supplies, and diagnoses and protects the undervoltage, overvoltage, overcurrent and overtemperature of the two power supplies at the same time, wherein the first power input circuit AA may include: a first power isolation chip A1, a first N-channel MOSFET tube group and a first current sampling resistor R1; wherein the first N-channel MOSFET tube group includes: an N-channel MOSFET tube (Qa1) and an N-channel MOSFET tube (Qa2). Similarly, the second power input circuit AB may include: a second power isolation chip (B1), a second N-channel MOSFET tube group and a second current sampling resistor R2; wherein the second N-channel MOSFET tube group includes: an N-channel MOSFET tube (Qb1) and an N-channel MOSFET tube (Qb2).

[0048] Under normal working conditions, the gate drive control MOSFET tubes Qa1 and Qa2 of the first power isolation chip A1 are in the on state. Similarly, the gate drive control MOSFET tubes Qb1 and Qb2 of the second power isolation chip B1 are in the on state. The first battery and the second battery are normally transmitted to Vout_A and Vout_B to ensure the normal operation of the back-end power chip, and the two power supplies are backed up for each other; when one of the batteries (the first battery or the second battery) is undervoltage, the power isolation chip (A1 or B1) of the undervoltage one monitors that the first battery or the second battery is lower than the set undervoltage shutdown threshold, and the gate drive of the power isolation chip A1 or B1 is automatically turned off within 1us, and the main control processing circuit C is notified of the undervoltage fault by setting the FAULT pin low, and the power supply a maintains Vout_B or Vout_A because the second battery or the first battery is normal.

[0049] When one battery (the first battery or the second battery) is overvoltage, the power isolation chip A1 or B1 on the overvoltage path monitors that the first battery or the second battery is higher than the set overvoltage shutdown threshold, and then automatically shuts down the gate drive of the power isolation chip A1 or B1 within 1us, and notifies the main control processing circuit C of the overvoltage fault by setting the FAULT pin low. The power supply a maintains Vout_B or Vout_A because the second battery B or the first battery is normal.

[0050] When one battery (the first battery or the second battery) has an overcurrent, the power isolation chip A1 or B1 on the overcurrent path monitors that the current on the current sampling resistor R1 or R2 is greater than the set threshold, and automatically shuts down the gate drive of the power isolation chip A1 or B1 within 1us, and notifies the main control processing circuit C of the overcurrent fault by setting the FAULT pin low; when one power isolation chip A1 or B1 monitors that its own temperature is higher than the temperature threshold, it automatically shuts down the gate drive of the power isolation chip A1 or B1, and notifies the main control processing circuit C of the overtemperature fault by setting the FAULT pin low.

[0051] In the above embodiment, the first power input circuit AA and the second power input circuit AB can independently monitor their own undervoltage, overvoltage, overcurrent, and overtemperature faults, and can shut down the drive in time, thereby realizing the function of protecting the power supply. The two power supplies not only work independently, but also when the other power supply is shut down due to a fault, it does not affect the normal operation of the back-end power supply, truly realizing the isolation of the dual power supplies while also providing redundant power supply.

[0052] Figure 4 This is a schematic diagram of the structure of the main control processing module provided in the embodiment of the present application. Figure 4As shown, the main control processing module C2 may include: a power management module C21 and a main control processing unit C22; wherein the power management unit C21 includes: a power management chip a1, a power management chip a2, a DC voltage conversion chip a3 and a DC voltage conversion chip a4, the power management chip a1 provides a multi-channel power supply f1-fn and a timing management of the multi-channel power supply for the MCU domain micro-processing unit domain (C221) in the main control processing unit C22; the power management chip a2 provides a CPU domain computing processing unit domain C222 in the main control processing unit C22 The timing management of multiple power supplies g1-gn and multiple power supplies, the DC voltage conversion chip a3 and the DC voltage conversion chip a4 provide power supplies h1 and h2 for the WKUP domain wake-up processing unit domain (C223) in the main control processing unit C22; at the same time, the power management chip a1 provides control signals b3, b4, and b5 to the power management chip a2, the DC voltage conversion chip a3, and the DC voltage conversion chip a4 to control the opening and closing of the above three chips. The embodiment of the present application can realize the independent power supply and timing management of different processing unit domains in the main control processing chip. When powered on, the power management unit C21 provides the required multi-channel power supply f1-fn, g1-gn, h1, and h2 to the main control processing unit C22. At the same time, the power management chip a1 manages the timing of power supply f1-fn, g1-gn, h1, and h2 through its own settings and control signals b3, b4, and b5 to ensure that the main control processing unit C22 can be powered on and off correctly and work normally. If low power consumption mode is required, the power supply output of the power management chip a2 can be cut off through the control signal b3. At this time, the CPU domain of the computing processing unit in the main control processing unit C22 does not work, which greatly reduces the power consumption of the main control processing unit C22 without affecting the normal operation of the MCU domain. The MCU domain and the CPU domain are completely independent, which can also provide functional safety of the system.

[0053] The embodiments of the present application can ensure the independence of power supply between different processing domains inside a high-performance processor chip, can flexibly enable low-power consumption mode (power consumption can be significantly reduced when CPU domain operation is not required), can improve system robustness, and can avoid interference from single point failures (FFT) of the MCU domain and CPU domain subsystems. In particular, when the MCU domain is used as a system safety monitor, the functional safety level of the system can be improved.

Figure 5As shown, the driving control processing module D2 includes: a power management unit D21 and a driving control processing unit D22, wherein the power management unit D21 includes: a power management chip b1, a power management chip b2, and a DC voltage conversion chip b3.

The embodiment of the present application can realize independent power supply and timing management of different processing unit domains in the driving control processing chip. When powered on, the power management unit D21 provides the required multi-power supplies i1-in, j1-jn, and k for the vehicle control processing unit D22. At the same time, the power management chip b3 controls c1 through its own settings and control signals to manage the timing of power supplies i1-in and j1-jn. The vehicle control processing unit D22 controls the timing of power supply k through control signals c2, thereby ensuring that the vehicle control processing unit D22 can be powered on and off correctly and operate normally.

[0055] Figure 6 This is a schematic diagram of the structure of the parking control processing module provided in the embodiment of the present application. Figure 6As shown, the parking control processing module F2 includes: a power management unit F21 and a parking control processing unit F22, wherein the power management module F21 includes: a power management chip c1, a power management chip c2, and a DC voltage conversion chip c3; the power management chip C1 provides multiple power supplies l1-ln and timing management of multiple power supplies for the MCU domain micro-processing unit domain F2211 in the parking control processing unit F22, the power management chip c2 provides multiple power supplies m1-mn and timing management of multiple power supplies for the CPU domain computing processing domain F2212 in the parking control processing unit F22, and the DC voltage conversion chip c3 provides power supply n for the video codec circuit F222; at the same time, the power management chip c1 provides a control signal control d1 for the power management chip c2, and the parking control processing unit F22 provides a control signal control d2 for the DC voltage conversion chip c1, so as to control the opening and closing of the above two chips. The embodiment of the present application can realize independent power supply and timing management of different processing unit domains in the parking control processing chip. When powered on, the power management unit F21 provides the required multi-channel power supplies l1-ln, m1-mn, and n for the parking control processing unit F22. At the same time, the power management chip c1 controls d1 through its own settings and control signals to manage the timing of power supplies l1-ln and m1-mn. The parking control processing unit F22 controls d2 through control signals to control the timing of power supply n, thereby ensuring that the parking control processing unit F22 can be powered on and off correctly and work normally.

[0056] Figure 7 This is a schematic diagram of the structure of the wake-up circuit provided in the embodiment of the present application. Figure 7 As shown, the first wake-up circuit G1 includes: a key door KL15 wake-up signal, a brake signal, and a CAN wake-up signal 1. The above signals are connected to the anodes of three diodes respectively, and the cathodes of the three diodes are connected together and connected to the enable terminal EN1 of the power management unit C21 and the wake-up pin WKUP1 of the power management module B1 respectively. The above four types of wake-up signals jointly control the opening and closing of the power management module C21 and the power management module B1. The second wake-up circuit G2 includes: CAN wake-up signals 2~n, LIN wake-up signals 1~n, Ethernet wake-up signals 1~n, timed wake-up signals RTC, and on-chip diagnostic OBD wake-up signals, which are respectively connected to the WKUP IO[1~n] of the wake-up processing unit WKUP domain of the main control processing module C2 to realize the wake-up of the main control processing unit C22.

[0057] In a specific embodiment of the present application, when the entire vehicle control domain controller is in a sleep state, the power management module B1 receives a wake-up signal (KL15, brake signal, CAN wake-up signal 1), the microprocessor module B2 starts normally and completes initialization, the microprocessor module B2 identifies the wake-up source and the wake-up scene, and the microprocessor module B2 determines whether it is necessary to wake up the main control processing module C2. If wake-up is required, the control signal a3 is controlled to wake up the main control processing module C2, and the main control processing module C2 starts normally; similarly, the microprocessor module B2 determines whether it is necessary to wake up the driving control processing module D2. If wake-up is required, the control signal a2 is controlled to wake up the driving control processing module D2, and the driving control processing module D2 starts normally; similarly, the microprocessor module B2 determines whether it is necessary to wake up the parking control processing module F2. If wake-up is required, the control signal a1 is controlled to wake up the parking control processing module F2, and the parking control processing module F2 starts normally.

[0058] In a specific embodiment of the present application, when the entire vehicle control domain controller is in a dormant state, the main control processing module C2 receives a wake-up signal (on-chip diagnostic signal OBD Activeline, CAN wake-up signal 2~n, Ethernet wake-up signal 1~n, RTC timing wake-up signal), the main control processing module C2 wakes up the power management unit C21 through the control signal b3, the main control processing module C2 wakes up the power management unit C21 through the control signal b3, the main control processing module C2 identifies the wake-up source and the wake-up scene, the main control processing module C2 determines whether it is necessary to wake up the microprocessor module B2, if it is necessary to wake up, the microprocessor module B2 is woken up by the control signal b3, and the microprocessor module B2 starts normally; similarly, the main control processing module C2 determines whether it is necessary to wake up the driving control processing module D2, if it is necessary to wake up, the driving control processing module D2 is woken up by the control signal b1, and the driving control processing module D2 starts normally; similarly, the main control processing module C2 determines whether it is necessary to wake up the parking control processing module F2, if it is necessary to wake up, the parking control processing module F2 is woken up by the control signal b2, and the parking control processing module F2 starts normally.

[0059] In the above embodiment, the scheme supports different wake-up scene recognition. If individual simple wake-up scenes only require a single processor module to process, only the relevant processing modules are powered on and work normally, such as the microprocessor module B2 is powered on and work alone, and the main control processing module C2 is powered on and work alone, and the controller system works in low power consumption mode; it also supports complex wake-up scenes and multiple processor modules work together to achieve more complex working scene processing functions. The scheme purposefully controls the power supply of each processor unit, and can flexibly control the power consumption of the entire integrated vehicle control domain controller while realizing the functions required by each wake-up scene.

[0060] The controller power supply system proposed in the embodiment of the present application includes a power input circuit, a microprocessor circuit, a main control processing circuit, a driving processing circuit, a wake-up circuit and a parking processing circuit; wherein the power input circuit includes: a first power input circuit and a second power input circuit; the first power input circuit and the second power input circuit are backed up for each other, and jointly provide power for the microprocessor circuit, the main control processing circuit, the driving processing circuit and the parking processing circuit. When a power input circuit fails, the other power input circuit can continue to provide power to the system, thereby ensuring the independence of power supply between different processing domains inside the high-performance processor chip, flexibly enabling low-power mode, improving system robustness, avoiding interference from single-point failures of the MCU domain and CPU domain subsystems, and especially improving the functional safety level of the system when the MCU domain is used as a system safety monitor. In the prior art, traditional cars are powered by a single battery, which causes the entire vehicle to be unable to work when the battery is low or damaged, so the single battery power supply method can no longer meet the demand. Therefore, compared with the prior art, the controller power supply system proposed in the embodiment of the present application can simultaneously support redundant power supply of dual power supplies, and realize isolation of the two power supplies, and has the diagnosis and protection functions of overvoltage, undervoltage, overcurrent, and overtemperature of the two power supplies, especially when the MCU domain is used as a system safety monitor, it can improve the functional safety level of the system; and the technical solution of the embodiment of the present application is simple and convenient to implement, easy to popularize, and has a wider range of applications.
