Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a power supply system of a vehicle controller and a method for controlling the power supply system of a vehicle controller. Background Art

[0002] With the increasing adoption of autonomous driving features in vehicles, dual-redundant power supply controllers are increasingly being used, particularly in critical regional controllers. Hardware-in-the-Loop (HIL) testing requires simulating vehicle operating conditions to thoroughly verify the performance of dual-redundant power supply controllers and ensure their proper function under various operating conditions.

[0003] However, existing HIL test environments cannot accurately test the power supply conditions encountered by controllers with dual redundant power supplies in real vehicles during simulation testing. Specifically, they cannot accurately test how the controller quickly and seamlessly switches to the backup power supply when the primary power supply fails, nor can they accurately test the controller's ability to maintain stability and accuracy in both power supply modes. For example, existing HIL test environments cannot simulate high-current switching, power supply failure scenarios, or obtain real-time voltage feedback. This makes it impossible to fully evaluate the controller's performance under complex power supply conditions, thereby reducing the confidence in test results and test efficiency.

[0004] To address the above-mentioned problems, no effective solutions have been proposed so far. Summary of the Invention

[0036] According to an embodiment of the present invention, a method for controlling a power supply system of a vehicle controller is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0037] In this embodiment, a power supply system for a vehicle controller is provided. Figure 1 FIG. 1 is a schematic diagram of a power supply system structure of a vehicle controller according to one embodiment of the present invention. Figure 1 As shown, the power supply system of the vehicle controller includes:

[0038] a first power distribution circuit 10, the first power distribution circuit being electrically connected to a first port of a target controller 20 and being used to control a power supply state of the target controller;

[0039] The second distribution circuit 30 is electrically connected to the second port of the target controller and is used to supply power to the target controller when the first distribution circuit fails, wherein the power supply of the second distribution circuit is less than the power supply of the first distribution circuit.

[0040] Specifically, the target controller is used to characterize the vehicle controller under test. The vehicle controller receives data from sensors, executes predefined algorithms or control logic, and sends commands to actuators to adjust the vehicle's various subsystems. The vehicle controller includes a regional controller (responsible for controlling multiple subsystems within a specific area) and a central control unit (coordinating the operation of the entire vehicle's electronic system).

[0041] Specifically, the target controller is connected to a first power distribution circuit via a primary power line and to a second power distribution circuit via a secondary power line. The first power distribution circuit is a high-power power supply module, while the second power distribution circuit is a low-power power supply module. The first power distribution circuit serves as the primary power supply module, while the second power distribution circuit serves as the backup power supply module. This dual-redundant connection ensures that if one power distribution circuit fails, the other can seamlessly take over and continue to provide a stable power supply to the target controller.

[0042] Specifically, in the vehicle hardware-in-the-loop (HIL) test environment, the controller's functionality, performance, and stability can be fully tested without using an actual vehicle. By controlling the first and second distribution circuits, test engineers can simulate the controller's behavior under different power supply conditions, including normal power supply and power failure scenarios. This simulation test can verify the controller's power supply and functionality in a laboratory environment, thereby discovering and resolving potential problems during the design phase, saving manpower and material costs of actual vehicle testing, and improving test efficiency.

[0043] Optionally, the first distribution circuit includes: a first relay, a first port of the first relay being electrically connected to a first port of the first DC power supply, for controlling a working state of the first DC power supply;

[0044] a first power switching board, wherein a first port of the first power switching board is electrically connected to a second port of the first DC power supply, and a second port of the first power switching board is electrically connected to a second port of the first relay, for controlling a working state of the first relay;

[0045] a second relay, wherein a first port of the second relay is electrically connected to a second port of the first relay, the second port of the second relay is electrically connected to the first simulated isolator, and a third port of the second relay is electrically connected to the first real isolator, for switching paths between the first simulated isolator and the first real isolator, wherein the second port of the first simulated isolator is electrically connected to the second port of the first real isolator, and the second port of the first real isolator is electrically connected to the first port of the target controller;

[0046] a first input / output card channel, the first input / output card channel being electrically connected to a fourth port of the second relay and being used to control a conduction state between the second relay and the first simulated isolator or the first real isolator;

[0047] The second input and output board channel is electrically connected to the second port of the first analog isolator and is used to collect status information of the target controller.

[0048] Specifically, Figure 2 FIG. 1 is a schematic diagram of a power supply system structure of another vehicle controller according to one embodiment of the present invention. Figure 2 As shown, the first distribution circuit includes: a first DC power supply 201, a first power switching board 202, a first relay 203, a second relay 204, a first analog isolator 205, a first real isolator 206, a first input and output board channel 207 and a second input and output board channel 208.

[0049] Specifically, the first DC power supply 201 serves as the power source for the first distribution circuit, providing basic electrical energy for the target controller's test environment. Since the first distribution circuit is a high-power power supply module, the first power switching board 202 has a relatively small current limit. Directly using the first power switching board 202 to control the on / off state of the first DC power supply 201 would affect the power supply current to the target controller. Therefore, a first relay 203 is provided in the first distribution circuit, and the first power switching board 202 controls the first relay 203 so that the first distribution circuit can provide a stable current to the target controller. The first relay 203 is an on / off relay. In other words, the first relay 202 controls the on / off state of the first distribution circuit according to the instructions of the first power switching board 202, thereby achieving conduction and disconnection between the first distribution circuit and the target controller through control of the first relay 203.

[0050] Specifically, the second relay 204 has a selection function. For example, the second relay 204 can be a two-choose-one relay. The first input / output board channel 207 controls the second relay 204 to switch between the first simulated isolator 205 and the first real isolator 206, thereby determining the current transmission path. The first simulated isolator 205 and the first real isolator 206 are used to simulate and implement real electrical isolation functions, respectively, enhancing the anti-interference capability and safety of the target controller.

[0051] Specifically, the second input / output board channel 208 is used to collect the operating voltage of the target controller, monitor the operating status of the target controller, and thereby determine the test result according to the operating status of the target controller.

[0052] For example, suppose a control module for a car's powertrain is tested, which is responsible for regulating engine output, monitoring battery status, and managing on-board power distribution. Since this module is critical to the safety and performance of the car, its anti-interference ability and power supply stability need to be verified under various extreme conditions. The first analog isolator 205 plays a key role in HIL testing. It can simulate various electrical interferences and power supply conditions that may be encountered in a real vehicle environment. For example: simulate power supply fluctuations and failures: During the driving of the car, the power supply system may suffer from voltage mutations or instantaneous power failures. The first analog isolator 205 can reproduce these power supply fluctuations and failures to test the performance of the control module under unstable power supply conditions. The analog isolator can adjust the power supply voltage and current without disconnecting to verify the robustness of the control module.

[0053] During actual vehicle operation or system integration testing, the first real isolator 206 provides physical electrical isolation to protect the control module from external electrical interference, ensuring safe and stable operation in complex electrical environments. For example, it isolates large battery current fluctuations: A car battery experiences large current fluctuations during startup or high-speed operation. Without proper isolation, these large current fluctuations could damage the control module's circuitry. By disconnecting the electrical connection and transmitting only signals, the real isolator 206 effectively isolates the control module from the effects of these large current fluctuations, protecting its circuitry from damage.

[0054] Furthermore, during HIL testing, the first simulated isolator 205 and the first real isolator 206 can work together. The first simulated isolator is used to create various simulated power supply and interference scenarios, while the second real isolator provides realistic electrical isolation within these simulated scenarios, simulating the controller's performance in a real vehicle environment. For example, when the test system attempts to simulate a high current surge during engine startup, the first simulated isolator 205 adjusts the power supply to simulate this event. Simultaneously, the first real isolator 206 provides the necessary isolation between the control module and the first DC power supply 201, ensuring that the control module is not actually damaged even under the simulated extreme conditions.

[0055] Optionally, the second power distribution circuit includes: a second power switching board, a first port of the second power switching board being electrically connected to the second DC power supply and configured to control the working state of the second DC power supply;

[0056] a third relay, wherein a first port of the third relay is electrically connected to a second port of the second power switching board, a second port of the third relay is electrically connected to the second analog isolator, and a third port of the third relay is electrically connected to the second real isolator, for switching paths between the second analog isolator and the second real isolator, wherein the second port of the second analog isolator is electrically connected to the second port of the second real isolator, and the second port of the second real isolator is electrically connected to the second port of the target controller;

[0057] a third input / output card channel, the third input / output card channel being electrically connected to a fourth port of the third relay and being used to control a conduction state between the third relay and the second simulated isolator or the second real isolator;

[0058] A fourth input / output board card channel is electrically connected to the second port of the second analog isolator and is used to collect status information of the target controller.

[0059] Specifically, Figure 3 FIG. 1 is a schematic diagram of a power supply system structure of another vehicle controller according to one embodiment of the present invention. Figure 3 As shown, the second distribution circuit includes: a second DC power supply 301, a second power switching board 302, a third relay 303, a second analog isolator 304, a second real isolator 305, a third input and output board channel 306 and a fourth input and output board channel 307.

[0060] Specifically, the second DC power supply 301 provides independent power to the second distribution circuit, forming a redundant backup with the first distribution circuit. The second power switching board 302 is similar to the first power switching board 202 in the first distribution circuit, but the control logic between the two is different. The second power switching board 302 is used to directly control the on / off state between the second DC power supply 301 and the third relay 303.

[0061] Specifically, the third relay 303 has a selection function. For example, the third relay 303 can be a two-choice relay. The third relay 303 is controlled by the third input / output board channel 306 to switch between the second simulated isolator 304 and the second real isolator 305, thereby determining the current transmission path. The second simulated isolator 304 and the second real isolator 305 are respectively used to simulate and implement real electrical isolation functions, enhancing the anti-interference capability and security of the target controller. The second simulated isolator 304 and the second real isolator 305 operate in the same manner as the first simulated isolator 205 and the first real isolator 206, and will not be further described here.

[0062] Specifically, the fourth input / output board channel 307 is used to collect the operating voltage of the target controller, monitor the operating state of the target controller, and thereby determine the test result according to the operating state of the target controller.

[0063] It is understandable that the circuit structures in the embodiments of the present invention can be combined according to needs and are not limited here.

[0064] In this embodiment, a control method for operating in the above-mentioned vehicle controller power supply system is provided. Figure 4 FIG. 1 is a flow chart of a method for controlling a vehicle controller power supply system according to one embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0065] Step S40, obtaining a first working state of the first distribution circuit and a second working state of the target controller;

[0066] In step S40, the above-mentioned first working state is used to characterize the state of each component in the first distribution circuit, including but not limited to: the first DC power supply in the first distribution circuit controls the first relay to be turned on through the first power switching board, and the second relay selects the first real isolator or the first simulated isolator.

[0067] The second working state is used to represent the current working state of the target controller. For example, the target controller is in a running state in the current test environment, that is, under test.

[0068] Step S42, controlling the third working state of the second distribution circuit based on the first working state and the second working state;

[0069] Specifically, after obtaining the working status of the first distribution circuit and the target controller, it is determined how to adjust the working status of the second distribution circuit according to the first working status and the second working status. In the process of adjusting the working status of the second distribution circuit, it includes: analyzing the status data of the first distribution circuit to determine whether a fault has occurred; and judging whether additional power support is required based on the current status of the target controller. If a fault is found in the first distribution circuit and the target controller requires power support, the second distribution circuit is triggered to enter the power supply state, that is, the third working state. In the process of triggering the second distribution circuit to enter the power supply state, the third relay is activated and the second power switching board is adjusted to ensure that the second distribution circuit can respond immediately and provide the required power to the target controller.

[0070] Step S44 , in response to the third working state indicating that the second distribution circuit is in a power supply state, controlling the second distribution circuit to supply power to the target controller.

[0071] Specifically, once the second distribution circuit is confirmed to be ready for power, the next step is to actually switch the power supply. The second relay is controlled to smoothly transition the target controller's power supply from the first distribution circuit to the second. The relay, acting as a physical switch, enables instant switching of the power supply path, ensuring a continuous power supply to the target controller without the controller noticing. After the second distribution circuit begins supplying power, the fourth I / O card channel continues to monitor the target controller's voltage feedback to confirm the success of the power supply process and that the target controller's status after powering on meets expectations.

[0072] Based on the above steps S40 to S44, a method of obtaining the first working state of the first distribution circuit and the second working state of the target controller is adopted, and the third working state of the second distribution circuit is controlled based on the first working state and the second working state, and in response to the third working state indicating that the second distribution circuit is in a power supply state, the second distribution circuit is controlled to supply power to the target controller, thereby achieving the purpose of being able to timely and accurately simulate and respond to power supply failures during the hardware-in-the-loop test of the vehicle controller, thereby achieving the technical effect of improving the test result confidence and test efficiency of the hardware-in-the-loop test of the vehicle controller, and further solving the technical problem of low test result confidence and test efficiency due to the inability to timely and accurately simulate and respond to power supply failures during the hardware-in-the-loop test of the vehicle controller.

[0073] Optionally, the third working state includes: a power supply state. In step S42, controlling the third working state of the second distribution circuit based on the first working state and the second working state includes:

[0074] Step S201: In response to determining that a second input / output board channel in a first distribution circuit receives an abnormal signal based on a first working state, and determining that a target controller is in a test state based on a second working state, controlling a second power supply switching board in a second distribution circuit to connect to a second DC power supply, and

[0075] Step S202: Using the third input / output card channel in the second distribution circuit to control the third control relay to select the second real isolator or the second simulated isolator, so as to control the second distribution circuit to be in a power supply state.

[0076] Specifically, when it is determined based on the first working state that the second input and output board channel in the first distribution circuit receives an abnormal signal, and when it is determined based on the second working state that the target controller is in the test state, the second power switching board in the second distribution circuit is controlled to connect to the second DC power supply.

[0077] Specifically, the first working state of the first distribution circuit is continuously monitored through the second input and output board channel of the first distribution circuit. When an abnormal signal is detected, it indicates that the first distribution circuit has failed or is underpowered. At the same time, the current state of the target controller is checked to ensure that the target controller is in a test state ready to accept power switching. If the target controller is performing critical operations or is in a state that is not suitable for switching, the switching can be temporarily delayed to avoid affecting the function or data integrity of the target controller. Once it is confirmed that the first distribution circuit has an abnormality and the target controller is in a switchable state, the second power switching board of the second distribution circuit will be activated to connect the second DC power supply, so that the second distribution circuit can start immediately and smoothly to provide the required power to the target controller.

[0078] Furthermore, before connecting the second distribution circuit, a decision must be made as to whether to use a second real isolator or a second simulated isolator. This step is accomplished using the third I / O card channel in the second distribution circuit, which controls the selection of the third control relay. The decision on which isolator to use can be based on a variety of factors, such as the current electromagnetic environment, the sensitivity of the controller, or the specific requirements of the test.

[0079] For example, the use of a second real isolator can provide physical electrical isolation and enhance the anti-interference ability of the system, especially in an environment with strong electromagnetic interference. This isolation is crucial for protecting the circuit and data integrity of the controller. On the other hand, the selection of a second simulated isolator is suitable for simulating different power supply scenarios during the test, such as power fluctuations, power outage recovery, etc., so as to evaluate the performance of the target controller under these conditions and ensure that it can operate stably in a real vehicle environment. Regardless of which isolator is selected, the on and off of the third control relay will ultimately determine whether the second distribution circuit is in a power supply state, that is, whether it starts to provide power to the target controller. Once the selection is completed and the corresponding isolator is activated, the third relay will turn on the circuit between the second power switching board and the target controller, realizing the power supply from the second distribution circuit to the target controller.

[0080] Based on the above steps S201 to S202, the status of the target controller is judged before switching the power supply to avoid sudden switching of the power supply when it is performing critical tasks, prevent data loss or abnormal operation, and ensure the stability and security of the test environment.

[0081] Optionally, the third working state includes: a power-off state. In step S42, controlling the third working state of the second distribution circuit based on the first working state and the second working state includes:

[0082] Step S203, in response to determining based on the first working state that the second input and output board channel does not receive an abnormal signal, and determining based on the second working state that the target controller is in a test state, controlling the second power switching board to be in a disconnected state to control the second distribution circuit to be in a power-off state.

[0083] Specifically, when it is determined based on the first working state that the second input and output board channel has not received an abnormal signal, and when it is determined based on the second working state that the target controller is in a test state, the second power switching board is controlled to be in a disconnected state to control the second distribution circuit to be in a power-off state.

[0084] Specifically, when the first distribution circuit is operating normally, meaning the second input / output board channel is not receiving any abnormal signals, and the target controller is in a test state, the second power switching board is controlled to be disconnected, thereby de-energizing the second distribution circuit. In other words, the second DC power supply is not activated, and the second distribution circuit remains inactive and "powered off" at this stage.

[0085] Furthermore, in the initial state, the first distribution circuit serves as the primary power supply module, and the target controller is powered by the first distribution circuit. The first DC power supply in the first distribution circuit, through the first power switching card, controls the first relay to conduct. Current flows through the second relay, selecting either the first real isolator or the first simulated isolator, providing stable power to the target controller. At this point, the second distribution circuit is in standby mode, and its second power switching card is disconnected.

[0086] Based on the above step S203, in response to determining that the second input and output board channel has not received an abnormal signal based on the first working state, and determining that the target controller is in a test state based on the second working state, the second power switching board is controlled to be in a disconnected state to control the second distribution circuit to be in a power-off state, which can avoid erroneous switching of redundant power supplies or unnecessary power supply, reduce interference, save energy consumption, and improve the autonomous controllability of the power supply path of the enhanced test system.

[0087] Optionally, the triggering condition of the abnormal signal includes at least one of the following: the voltage of the first DC power supply in the first distribution circuit is lower than a preset voltage threshold, and the voltage of the first DC power supply is not in a preset voltage operating range.

[0088] Specifically, the voltage of the first DC power supply being lower than a preset voltage threshold is used to indicate that when it is detected that the voltage of the first DC power supply is lower than a preset lower limit, the first distribution circuit is determined to be "voltage dropped" or "underpowered".

[0089] The voltage of the first DC power supply is not within the preset voltage operating range, which indicates that when it is detected that the voltage fluctuation of the first DC power supply is not within a certain range, it is determined that the voltage fluctuation of the first distribution circuit is too large.

[0090] For example, if the output voltage of the first DC power supply is lower than the set voltage threshold (such as 10.5V), it is considered that the main power supply is insufficient; if the output voltage of the first DC power supply is not within the set normal operating voltage range (such as 11.0V~14.0V), it is considered that the power supply fluctuation is abnormal.

[0091] Through the above judgment, accurate monitoring of the working status of the power supply can be achieved, providing a trigger basis for the subsequent startup of the second distribution circuit.

[0092] Optionally, the control method of the vehicle controller power supply system further includes:

[0093] Step S45, in response to the second distribution circuit being in the power supply state, controlling the fourth input and output board channel in the second distribution circuit to monitor the second working state;

[0094] Specifically, when the second power distribution circuit is activated and providing power to the target controller, meaning the backup power supply is connected, data is collected using the fourth input / output card channel. This ensures the controller remains stable while powered by the backup power supply, providing real-time visibility into its operating status and providing essential data for further testing and judgment. For example, data such as the target controller's supply voltage, output signal, current, and power status feedback can be collected.

[0095] Step S46: determining a test result of the target controller based on the second working state.

[0096] Specifically, based on the second working state, the operating performance of the target controller in the backup power supply state is analyzed, such as: whether it is successfully started; whether it responds to the test platform within the set time; whether the expected functional signal is output; whether the error code, reset flag or failure status is recorded, etc.

[0097] Furthermore, based on the monitoring data, target controller test result information is generated, such as whether the target controller operates normally under the backup power supply; whether the target controller has performance degradation or malfunction; or whether the target controller is incompatible with or fails the redundant power supply.

[0098] Based on the above steps S45 to S46, in response to the second distribution circuit being in the power supply state, the fourth input and output board channel in the second distribution circuit is controlled to monitor the second working state; the test result of the target controller is determined based on the second working state, and the working state of the target controller is continued to be tracked after the power supply switching is completed to ensure the integrity and effectiveness of the entire test process.

[0099] Figure 5FIG. 1 is a flow chart of another method for controlling a vehicle controller power supply system according to one embodiment of the present invention. Figure 5 As shown, the process includes the following steps:

[0100] Step S501, obtaining a first working state of a first distribution circuit and a second working state of a target controller;

[0101] Step S502: In response to determining that the second input / output card channel in the first distribution circuit receives an abnormal signal based on the first working state, and determining that the target controller is in the test state based on the second working state, controlling the second power switching card in the second distribution circuit to connect to the second DC power supply, and controlling the third control relay to select the second real isolator or the second simulated isolator using the third input / output card channel in the second distribution circuit to control the second distribution circuit to be in the power supply state;

[0102] Step S503, in response to the third working state indicating that the second distribution circuit is in a power supply state, controlling the second distribution circuit to supply power to the target controller;

[0103] Step S504, in response to the second distribution circuit being in the power supply state, controlling the fourth input and output board channel in the second distribution circuit to monitor the second working state;

[0104] Step S505: In response to determining that the second input / output board channel does not receive an abnormal signal based on the first working state, and determining that the target controller is in a test state based on the second working state, controlling the second power switching board to be in a disconnected state to control the second power distribution circuit to be in a power-off state;

[0105] Step S506, controlling the first input and output board channel in the first distribution circuit to monitor the second working state;

[0106] Step S507: determining a test result of the target controller based on the second working state.

[0107] For example, the above-described vehicle controller power supply system control method is applied in a hardware-in-the-loop simulation test system for an automotive zone controller. Initially, the first distribution circuit serves as the primary power supply module. The first DC power supply, through the first power switching card, controls the first relay to conduct. Current flows through the first relay, selecting either the first real isolator or the first simulated isolator, providing stable power to the target controller. At this point, the second distribution circuit is in standby mode, and its second power switching card is disconnected.

[0108] When the first DC power supply in the first distribution circuit experiences excessive voltage fluctuations or a sudden power outage, the second I / O card channel detects the abnormal signal, and the HIL device controls the second power switching card in the second distribution circuit to connect the second DC power supply. In the second distribution circuit, the third I / O card channel controls the third relay to select either the second real isolator or the second simulated isolator, controlling the second DC power supply to power the target controller. This achieves seamless power switching and ensures testing of the target controller on the HIL test bench. The target controller can also perform voltage sampling via the fourth I / O card channel in the second distribution circuit, monitoring the voltage status of the second distribution circuit in real time.

[0109] Based on the above steps S501 to S507, a method of obtaining the first working state of the first distribution circuit and the second working state of the target controller is adopted, and the third working state of the second distribution circuit is controlled based on the first working state and the second working state. In response to the third working state indicating that the second distribution circuit is in a power supply state, the second distribution circuit is controlled to supply power to the target controller, thereby achieving the purpose of being able to timely and accurately simulate and respond to power supply failures during the hardware-in-the-loop test of the vehicle controller, thereby achieving the technical effect of improving the test result confidence and test efficiency of the hardware-in-the-loop test of the vehicle controller, and further solving the technical problem of low test result confidence and test efficiency due to the inability to timely and accurately simulate and respond to power supply failures during the hardware-in-the-loop test of the vehicle controller.
