Description

Technical Field

[0001] This application relates to the field of electronic circuit technology, and in particular to a power supply device, power supply control method and related products. Background Technology

[0002] The supply of high-pressure gas in air suspension systems has traditionally relied on electrically driven compressors, which essentially compress the gas by changing the working volume of a cylinder. The motor construction and control logic of these miniature compressors are relatively straightforward; the suspension controller switches the air pump motor on and off based on system pressure, temperature, and operating time. The air pump motor cannot operate for extended periods; exceeding the predetermined total load and temperature range will damage the compressor.

[0003] However, the current power supply scheme for air pump motors results in a high failure rate and poor reliability of the air pump motor compressor. Summary of the Invention

[0004] This application provides a power supply device, a power supply control method, and related products, which can reduce the damage rate of the compressor in the air pump motor and improve its reliability.

[0005] In a first aspect, embodiments of this application provide a power supply device applied to a first motor. The power supply device includes: a first power source, a first control unit, a first power distribution unit, and a first switch unit. A first terminal of the first power distribution unit is connected to the first power source, and a second terminal of the first power distribution unit is connected to the first terminal of the first switch unit; the second terminal of the first switch unit is connected to the first motor. The first control unit controls the first switch unit to close and controls the first power distribution unit to open power distribution. This power supply device is used to supply power to the first motor.

[0006] In this embodiment, a power supply device is provided. Power is supplied to a first motor by controlling the closure of a first switch unit and the activation of a first power distribution unit within the power supply device. It is understood that the first control unit jointly controls the first switch unit and the first power distribution unit. Power can only be supplied to the first motor when the first switch unit is closed and the first power distribution unit is activated. If either condition is not met, power supply to the first motor will cease. Therefore, software and / or hardware failures of the first power distribution unit that could lead to uncontrolled power supply to the first motor can be avoided, thereby reducing the compressor damage rate of the air pump motor and improving reliability.

[0007] Optionally, the third terminal of the first switching unit is connected to the first control unit, and the first control unit can send control commands through the connection channel between itself and the third terminal of the first switching unit to control the first switching unit to close.

[0008] Optionally, the fourth terminal of the first switching unit is grounded.

[0009] Optionally, the first power distribution unit is connected to the first control unit via wired or wireless means. The first control unit can communicate via wired or wireless means with the first power distribution unit through the connection channel to send control commands to control the first power distribution unit to start power distribution.

[0010] In one possible implementation, the first switching unit closes before the first power distribution unit starts power distribution.

[0011] In this embodiment, before controlling the first power distribution unit to start power distribution, it is necessary to control the first switch unit to close first. This can avoid the impact of intrusion current and shutdown current on the first switch unit when a large current load is directly connected, and improve the electrical life of the first switch unit.

[0012] Optionally, since the first switching unit is actually under load after the load circuit stabilizes, the current specification of the first switching unit can be appropriately reduced to reduce costs and optimize noise, vibration, and harshness (NVH).

[0013] In one possible implementation, if the operating time of the first motor exceeds a first threshold and / or the temperature of the first motor exceeds a second threshold, the first control unit is further configured to control the first power distribution unit to shut down power distribution and / or control the first switching unit to disconnect.

[0014] In this embodiment, the first control unit jointly controls the first switching unit and the first power distribution unit. When the first switching unit is disconnected and / or the first power distribution unit shuts off power distribution, the power supply to the first motor can be stopped. By utilizing the dual-path control of the first switching unit and the first power distribution unit, it is possible to avoid uncontrolled power supply to the first motor due to software and / or hardware failure of the first power distribution unit, thereby reducing the damage rate of the compressor of the air pump motor and improving reliability.

[0015] Optionally, the first threshold and the second threshold are not fixed values ​​and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0016] In one possible implementation, if the first switching unit is stuck together, the first control unit is also used to control the first power distribution unit to shut down the power distribution.

[0017] In this embodiment, when the first switch unit is stuck together, the power supply to the first motor can be stopped by controlling the first power distribution unit to shut down the power distribution. By using the dual-path control of the first switch unit and the first power distribution unit, the power supply to the first motor can be prevented from becoming uncontrolled due to the first switch unit sticking together, thereby reducing the damage rate of the compressor of the air pump motor and improving reliability.

[0018] Optionally, the first switch unit is stuck together, which can be understood as the fixed contact and the movable contact of the first switch unit melting and welding together, thus making it impossible to control the disconnection normally.

[0019] In one possible implementation, when the first control unit controls the first switch unit to disconnect and controls the first power distribution unit to start power distribution, and the first power distribution unit collects a first circuit current supplying power to the first motor that is greater than 0, the first control unit is also used to determine that the first switch unit is stuck together.

[0020] In this embodiment, the first switching unit can detect potential sticking problems by collecting the first circuit current that supplies power to the first motor through the first power distribution unit, thereby stopping the power supply to the first motor in a timely manner and ensuring the reliability of the power supply system.

[0021] In one possible implementation, the first end of the first switching unit is connected to the first control unit; the first control unit is also used to collect the second circuit current for powering the first motor through the connection channel between the first end of the first switching unit and the first control unit; when the first control unit controls the first switching unit to disconnect and controls the first power distribution unit to start power distribution, and the second circuit current is greater than 0, the first control unit is also used to determine that the first switching unit is stuck.

[0022] In this embodiment, the sticking problem of the first switch unit can be detected by collecting the second circuit current that supplies power to the first motor through the connection channel between the first end of the first switch unit and the first control unit. This allows for timely cessation of power supply to the first motor and avoids the failure of the first power distribution unit's current acquisition or network communication failure, which could prevent the timely detection of the sticking problem of the first switch unit. This ensures the reliability of the power supply system.

[0023] In one possible implementation, the third terminal of the first switching unit is connected to the first control unit; the first control unit is also used to acquire a first voltage through the connection channel between the third terminal of the first switching unit and the first control unit; when the first control unit controls the first switching unit to open and the first voltage is greater than 0, the first control unit is also used to determine that the first switching unit is faulty.

[0024] In this embodiment, the first voltage collected through the connection channel between the third terminal of the first switching unit and the first control unit can be used to detect whether the first switching unit is faulty. If the first voltage is greater than 0, it indicates that the first switching unit cannot disconnect normally, so the fault of the first switching unit can be reported in time to ensure the reliability of the power supply system.

[0025] In one possible implementation, if the communication abnormality duration between the first control unit and the first power distribution unit exceeds a third threshold, the first control unit is further configured to control the first power distribution unit to shut down power distribution and / or control the first switching unit to disconnect.

[0026] In this embodiment, the communication between the first power distribution unit and the first control unit can be verified to ensure that, in case of abnormality, the first power distribution unit can be controlled to shut down power distribution and / or the first switching unit can be controlled to disconnect, so as to stop power supply to the first motor in a timely manner and ensure the reliability of the power supply system.

[0027] Optionally, the third threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0028] In one possible implementation, if the duration of continuous operation of the first power distribution unit exceeds a fourth threshold and / or the first control unit malfunctions, the first power distribution unit shuts down power distribution.

[0029] In this embodiment, the first power distribution unit is equipped with control logic for continuous working time, which enables the power distribution to be shut down after the first power distribution unit has been working continuously for a certain period of time, and / or, when the first control unit fails, the first power distribution unit shuts down the power distribution to stop supplying power to the first motor in a timely manner, thereby ensuring the reliability of the power supply system.

[0030] Optionally, the fourth threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0031] In one possible implementation, the power supply device further includes a second switching unit. The second switching unit is connected in series with the first switching unit; the first control unit is used to control the closing of the second switching unit.

[0032] In this embodiment, the first control unit controls the second switch unit in the power supply device to close, and jointly controls the first switch unit in the power supply device to close and the first power distribution unit to open power distribution, thereby supplying power to the first motor. It is understood that the first control unit jointly controls the first switch unit, the first power distribution unit, and the second switch unit. Power can only be supplied to the first motor when the first switch unit is closed, the second switch unit is closed, and the first power distribution unit is open. If any condition is not met, power supply to the first motor will stop. Therefore, it can avoid software and / or hardware failure of the first power distribution unit leading to uncontrolled power supply to the first motor, thereby reducing the damage rate of the compressor of the air pump motor and improving reliability.

[0033] Optionally, the second switching unit can be in a normally closed state, which has lower requirements for electrical life.

[0034] In one possible implementation, if the first switch unit is stuck and the first power distribution unit fails to control, the first control unit is used to control the second switch unit to disconnect.

[0035] In this embodiment, when the first switch unit is stuck together and the first power distribution unit fails to control, the power supply to the first motor can be cut off by controlling the second switch unit to disconnect, thereby ensuring the safety and reliability of the power supply system.

[0036] Secondly, embodiments of this application provide a power supply control method applied to a power supply device as described in the first aspect or any possible implementation thereof, the power supply device being connected to a first motor; the power supply control method includes:

[0037] The first switch unit in the control power supply device is closed, and the first power distribution unit in the control power supply device is opened to distribute power, so as to enable the control power supply device to supply power to the first motor.

[0038] This application provides a power supply control method that supplies power to a first motor by controlling the closing of a first switch unit and the activation of a first power distribution unit in the power supply device. It is understood that by jointly controlling the first switch unit and the first power distribution unit, power can only be supplied to the first motor when the first switch unit is closed and the first power distribution unit is activated. If either condition is not met, power supply to the first motor will stop. Therefore, this avoids uncontrolled power supply to the first motor due to software and / or hardware failure of the first power distribution unit, thereby reducing the damage rate of the compressor in the air pump motor and improving reliability.

[0039] In one possible implementation, the timing of closing the first switching unit is before the timing of opening the first power distribution unit for power distribution.

[0040] In this embodiment, before controlling the first power distribution unit to start power distribution, it is necessary to control the first switch unit to close first. This can avoid the impact of intrusion current and shutdown current on the first switch unit when a large current load is directly connected, and improve the electrical life of the first switch unit.

[0041] Optionally, since the first switching unit is actually under load after the load circuit stabilizes, the current specification of the first switching unit can be appropriately reduced to reduce costs and optimize noise, vibration, and harshness (NVH).

[0042] In one possible implementation, the power supply control method further includes:

[0043] The system acquires the operating time and / or temperature of the first motor; if the operating time of the first motor exceeds a first threshold and / or the temperature of the first motor exceeds a second threshold, the system controls the first power distribution unit to shut down the power distribution and / or controls the first switch unit to open.

[0044] In this embodiment, the first switching unit and the first power distribution unit are jointly controlled. When the first switching unit is disconnected and / or the first power distribution unit shuts off power distribution, the power supply to the first motor can be stopped. By utilizing the dual-path control of the first switching unit and the first power distribution unit, it is possible to avoid uncontrolled power supply to the first motor due to software and / or hardware failure of the first power distribution unit, thereby reducing the damage rate of the compressor of the air pump motor and improving reliability.

[0045] Optionally, the first threshold and the second threshold are not fixed values ​​and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0046] In one possible implementation, the power supply control method further includes:

[0047] If adhesion is detected in the first switching unit, the first power distribution unit is controlled to shut down the power distribution.

[0048] In this embodiment, when the first switch unit is detected to be stuck, the power supply to the first motor can be stopped by controlling the first power distribution unit to shut down the power distribution. By using the dual-path control of the first switch unit and the first power distribution unit, the power supply to the first motor can be prevented from being out of control due to the first switch unit sticking, thereby reducing the damage rate of the compressor of the air pump motor and improving reliability.

[0049] Optionally, the first switch unit is stuck together, which can be understood as the fixed contact and the movable contact of the first switch unit melting and welding together, thus making it impossible to control the disconnection normally.

[0050] In one possible implementation, the power supply control method further includes:

[0051] The first switch unit is controlled to disconnect and the first power distribution unit is controlled to start power distribution; if the first circuit current supplying power to the first motor is greater than 0 when the first power distribution unit collects data, it is determined that the first switch unit is stuck.

[0052] In this embodiment, the first switching unit can detect potential sticking problems by collecting the first circuit current that supplies power to the first motor through the first power distribution unit, thereby stopping the power supply to the first motor in a timely manner and ensuring the reliability of the power supply system.

[0053] In one possible implementation, the power supply control method further includes:

[0054] The system controls the first switching unit to disconnect and the first power distribution unit to start power distribution; it collects the second circuit current supplying power to the first motor through the connection channel between the first switching unit and the first control unit in the power supply device; and it determines that the first switching unit is stuck when the second circuit current is greater than 0.

[0055] In this embodiment, the sticking problem of the first switch unit can be detected by collecting the second circuit current that supplies power to the first motor through the connection channel between the first switch unit and the first control unit. This allows for timely cessation of power supply to the first motor and avoids the failure of the first power distribution unit's current acquisition or network communication failure, which could prevent the timely detection of the sticking problem of the first switch unit. This ensures the reliability of the power supply system.

[0056] In one possible implementation, the power supply control method further includes:

[0057] The first switching unit is disconnected; a first voltage is collected through the connection channel between the first switching unit and the first control unit in the power supply device; if the first voltage is greater than 0, the first switching unit is determined to be faulty.

[0058] In this embodiment, the first voltage collected through the connection channel between the first switching unit and the first control unit can be used to detect whether the first switching unit is faulty. If the first voltage is greater than 0, it indicates that the first switching unit cannot disconnect normally, so the fault of the first switching unit can be reported in time to ensure the reliability of the power supply system.

[0059] In one possible implementation, the power supply control method further includes:

[0060] The duration of communication disconnection between the first control unit and the first power distribution unit in the power supply device is obtained; if the abnormal communication duration between the first control unit and the first power distribution unit exceeds a third threshold, the first power distribution unit is controlled to shut down power distribution and / or the first switching unit is controlled to disconnect.

[0061] In this embodiment, the communication between the first power distribution unit and the first control unit can be verified to ensure that, in case of abnormality, the first power distribution unit can be controlled to shut down power distribution and / or the first switching unit can be controlled to disconnect, so as to stop power supply to the first motor in a timely manner and ensure the reliability of the power supply system.

[0062] Optionally, the third threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0063] In one possible implementation, the power supply control method further includes:

[0064] The system obtains the duration of continuous operation of the first power distribution unit and / or the operating status of the first control unit in the power supply device; if the duration of continuous operation of the first power distribution unit exceeds the fourth threshold and / or the first control unit malfunctions, the system controls the first power distribution unit to shut down power distribution.

[0065] In this embodiment, control logic is set for the continuous working time of the first power distribution unit, which controls the power distribution to be shut down after the first power distribution unit has been working continuously for a certain period of time, and / or controls the first power distribution unit to shut down the power distribution when the first control unit fails, so as to stop supplying power to the first motor in a timely manner and ensure the reliability of the power supply system.

[0066] Optionally, the fourth threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0067] In one possible implementation, the power supply control method further includes:

[0068] The second switch unit in the control power supply device is closed.

[0069] In this embodiment, the second switch unit in the control power supply device is closed, and in conjunction with the closure of the first switch unit and the activation of the first power distribution unit, power is supplied to the first motor. It is understood that by jointly controlling the first switch unit, the first power distribution unit, and the second switch unit, power can only be supplied to the first motor when the first switch unit is closed, the second switch unit is closed, and the first power distribution unit is activated. If any condition is not met, power supply to the first motor will cease. Therefore, software and / or hardware failure of the first power distribution unit can prevent uncontrolled power supply to the first motor, thereby reducing the compressor damage rate of the air pump motor and improving reliability.

[0070] Optionally, the second switching unit can be in a normally closed state, which has lower requirements for electrical life.

[0114] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described below with reference to the accompanying drawings.

[0115] The terms "first" and "second," etc., used in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0116] The term "embodiment" as used herein means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that, unless otherwise specified or logically conflicting, the terminology and / or descriptions between the various embodiments of this application are consistent and can be mutually referenced, and technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0117] It should be understood that in this application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three or more, and "and / or" is used to describe the relationship between related objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0118] It should be noted that, in this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information for the purpose of instructing A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.

[0119] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a correlation between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various information, thereby reducing instruction overhead to some extent. The information to be instructed can be sent as a whole or divided into multiple sub-information units, and the sending period and / or timing of these sub-information units can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information units can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device.

[0120] It should be noted that in this application, "send" can be understood as "output" and "receive" can be understood as "input". "Send information to A", where "to A" simply indicates the direction of information transmission, and A is the destination, does not limit "send information to A" to a direct transmission over the air interface. "Send information to A" includes sending information directly to A, as well as sending information indirectly to A through a transmitter. Therefore, "send information to A" can also be understood as "outputting information destined for A". Similarly, "receive information from A" indicates that the source of the information is A, including receiving information directly from A, as well as receiving information indirectly from A through a receiver. Therefore, "receive information from A" can also be understood as "inputting information from A".

[0121] This application provides a power supply device, a power supply control method, and related products, applied in the field of electronic circuit technology, such as the power supply control of the air pump motor in a vehicle's air suspension system. To better understand the technical solution of this application, the relevant terms and concepts that may be involved in the embodiments of this application are introduced below.

[0122] An intelligent distribution unit (IDU) is a power distribution and management device that integrates advanced technology and intelligent functions. It employs advanced sensors, communication technologies, and data processing technologies to achieve real-time monitoring, control, protection, and management of the power system. Intelligent distribution units possess multiple functions, including power parameter measurement, power quality monitoring, fault detection and location, and remote control, providing strong support for the safe and efficient operation of the power system.

[0123] The supply of high-pressure gas in air suspension systems has so far primarily relied on electrically driven compressors, which essentially compress the gas by changing the working volume of the cylinder. The motor construction and control logic of these miniature compressors are relatively straightforward; the suspension controller switches the air pump motor on and off based on system pressure, temperature, and operating time.

[0124] Air pump motors cannot operate for extended periods. Exceeding the predetermined total load and temperature range will damage the compressor. Generally, exceeding the predetermined total load (≥25% duty cycle) and temperature range (≥125℃) will damage the compressor.

[0125] However, the power supply scheme for the air pump motor leads to a higher failure rate and lower reliability of the air pump motor compressor.

[0126] For details, please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of a power supply device provided in an embodiment of this application.

[0127] like Figure 1 As shown, the power supply device includes, but is not limited to, a power supply, a suspension controller, a fuse box, and a relay.

[0128] The power supply is connected to the fuse box, the fuse box is connected to the relay, the relay is connected to the air pump motor, and the air pump motor is grounded.

[0129] Optionally, the power supply can consist of a battery and a direct current to direct current (DC-DC) converter, which can output DC (or near-DC) power at different voltages.

[0130] The suspension controller controls the power supply to the air pump motor by controlling the opening and closing of relays.

[0131] However, in the above-mentioned "relay + fuse box" power supply scheme, the traditional fuse is affected by process, overcurrent, temperature and other factors, and the melting time is uncontrollable. In addition, the (normally open) relay is generally a non-metal oxide semiconductor (MOS) tube, which has a high random hardware failure rate. The power supply to the air pump motor is uncontrollable, which will lead to a high damage rate of the air pump motor compressor and poor reliability.

[0132] For details, please refer to [link / reference]. Figure 2 , Figure 2 This is a schematic diagram of another power supply device provided in an embodiment of this application.

[0133] like Figure 2The power supply device includes, but is not limited to, a power supply, a suspension controller, and an IDU.

[0134] The power supply is connected to the IDU, the IDU is connected to the air pump motor, and the air pump motor is grounded.

[0135] Optionally, the power supply can consist of a battery and a DC-DC converter, capable of outputting DC (or near-DC) power at different voltages.

[0136] The suspension controller controls the power supply to the air pump motor by controlling the IDU to enable or disable the power distribution function.

[0137] However, the power supply scheme of the above-mentioned "IDU" has a single point of failure problem. If there are software or hardware problems with the IDU, such as the IDU failing to respond to the disconnect control command of the suspension controller, it will cause the air pump motor to be abnormally powered, thus making the power supply of the air pump motor uncontrollable, resulting in a high damage rate and poor reliability of the air pump motor compressor.

[0138] In view of this, this application provides a power supply device and a corresponding power supply control method based on the power supply device, which is applied in the field of electronic circuit technology, such as the power supply control of the air pump motor of a vehicle's air suspension system. This method can reduce the damage rate of the air pump motor's compressor and improve its reliability.

[0139] Please see Figure 3 , Figure 3 This is a schematic diagram of another power supply device provided in an embodiment of this application.

[0140] like Figure 3 As shown, the power supply device 30 includes, but is not limited to:

[0141] First power supply 301, first control unit 302, first power distribution unit 303, first switch unit 304.

[0142] In this configuration, the first terminal 303a of the first power distribution unit 303 is connected to the first power supply 301, the second terminal 303b of the first power distribution unit 303 is connected to the first terminal 304a of the first switch unit 304, the second terminal 304b of the first switch unit 304 is connected to the first motor, and the first motor is grounded.

[0143] The first control unit 302 is used to control the first switch unit 304 to close and control the first power distribution unit 303 to open the power distribution. The power supply device 30 is used to supply power to the first motor.

[0144] Optionally, the first power supply 301 may consist of a battery and a DC-DC converter, which can output DC (or near-DC) power supplies of different voltages.

[0145] Optionally, the first control unit 302 may be a device equipped with a processor / chip that can execute computer execution instructions, or it may be a processor / chip that can execute computer execution instructions, for outputting control instructions to realize control of power supply to the first motor.

[0146] Optionally, the first power distribution unit 303 may include, but is not limited to, an IDU. The fast turn-off characteristics (up to hundreds of microseconds / µs) of the metal oxide semiconductor field-effect transistor (MOSFET) within the IDU can enable rapid disconnection to supply power to the first motor.

[0147] Optionally, the first switching unit 304 may include, but is not limited to, a relay.

[0148] Optionally, the first motor may include, but is not limited to, an air pump motor. It is understood that the power supply device in this application embodiment can be used not only for air pump motors, but also in redundant power supply schemes for other charging devices where prolonged power supply is risky; this application embodiment does not impose any limitations on this.

[0149] It is understandable that the first control unit 302 jointly controls the first switching unit 304 and the first power distribution unit 303. Power can be supplied to the first motor only when the first switching unit 304 is closed and the first power distribution unit 303 is turned on. If either condition is not met, power will be stopped to the first motor. Therefore, it can avoid the loss of control over power supply to the first motor due to software and / or hardware failure of the first power distribution unit 303, thereby reducing the damage rate of the compressor of the first motor and improving reliability.

[0150] Optionally, the third terminal 304c of the first switching unit 304 is connected to the first control unit 302. The first control unit 302 can send control commands through the connection channel between itself and the third terminal 304c of the first switching unit 304 to control the first switching unit 304 to close.

[0151] Optionally, the fourth terminal of the first switching unit 304 is grounded.

[0152] Optionally, the third terminal 303c of the first power distribution unit 303 is connected to the first control unit 302 via wired or wireless means, for example, via a controller area network (CAN) bus. The first control unit 302 can communicate via wired or wireless means with the third terminal 303c of the first power distribution unit 303 to send control commands to control the first power distribution unit 303 to start power distribution.

[0153] In one possible embodiment, the first switch unit 304 closes before the first power distribution unit 303 starts power distribution.

[0154] Understandably, before controlling the first power distribution unit 303 to start power distribution, it is necessary to control the first switch unit 304 to close first. This can avoid the impact of inrush current and shutdown current on the first switch unit 304 when a large current load is directly connected, and improve the electrical life of the first switch unit 304.

[0155] Optionally, since the first switching unit 304 is actually under load after the load circuit stabilizes, the current specification of the first switching unit 304 can be appropriately reduced to reduce costs and optimize noise, vibration, and harshness (NVH).

[0156] In one possible embodiment, if the operating time of the first motor is greater than a first threshold and / or the temperature of the first motor is greater than a second threshold, the first control unit 302 is further configured to control the first power distribution unit 303 to shut down the power distribution and / or control the first switch unit 304 to disconnect.

[0157] Understandably, the first control unit 302 jointly controls the first switching unit 304 and the first power distribution unit 303. When the first switching unit 304 is disconnected and / or the first power distribution unit 303 shuts off power distribution, the power supply to the first motor can be stopped. Utilizing the dual-path control of the first switching unit 304 and the first power distribution unit 303 can prevent software and / or hardware failures of the first power distribution unit 303 from causing uncontrolled power supply to the first motor, thereby reducing the damage rate of the air pump motor's compressor and improving reliability.

[0158] Optionally, the first threshold and the second threshold are not fixed values ​​and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0159] In one possible embodiment, if the first switch unit 304 is stuck together, the first control unit 302 is also used to control the first power distribution unit 303 to shut down the power distribution.

[0160] Understandably, when the first switch unit 304 is stuck, the power supply to the first motor can be stopped by controlling the first power distribution unit 303 to shut down the power distribution. By using the dual-path control of the first switch unit 304 and the first power distribution unit 303, the loss of control over the power supply to the first motor caused by the sticking of the first switch unit 304 can be avoided, thereby reducing the damage rate of the compressor of the air pump motor and improving reliability.

[0161] Optionally, the first switch unit 304 is stuck together, which can be understood as the fixed contact and the movable contact of the first switch unit 304 melting and welding together, thus making it impossible to control the disconnection normally.

[0162] In one possible embodiment, when the first control unit 302 controls the first switch unit 304 to disconnect and controls the first power distribution unit 303 to start power distribution, and the first power distribution unit 303 collects the first circuit current supplying power to the first motor which is greater than 0, the first control unit 302 is also used to determine that the first switch unit 304 is stuck.

[0163] Understandably, the first switching unit 304 can detect potential sticking problems by collecting the first circuit current that supplies power to the first motor through the first power distribution unit 303, thereby allowing the power supply to the first motor to be stopped in a timely manner and ensuring the reliability of the power supply system.

[0164] In one possible embodiment, the first end 304a of the first switching unit 304 is connected to the first control unit 302.

[0165] For details, please refer to [link / reference]. Figure 4 , Figure 4 This is a schematic diagram of another power supply device provided in an embodiment of this application.

[0166] like Figure 4 As shown, the first control unit 302 is also used to collect the second circuit current that supplies power to the first motor through the connection channel between the first terminal 304a of the first switch unit 304 and the first control unit 302; when the first control unit 302 controls the first switch unit 304 to disconnect and controls the first power distribution unit 303 to start power distribution, and the second circuit current is greater than 0, the first control unit 302 is also used to determine that the first switch unit 304 is stuck.

[0167] It is understandable that the second circuit current supplying power to the first motor can be collected through the connection channel between the first terminal 304a of the first switch unit 304 and the first control unit 302 to detect potential sticking problems in the first switch unit 304. This allows for timely cessation of power supply to the first motor and avoids the failure of current collection in the first power distribution unit 303 or network communication failure, which could prevent timely detection of potential sticking problems in the first switch unit 304, thus ensuring the reliability of the power supply system.

[0168] In one possible embodiment, the third terminal 304c of the first switching unit 304 is connected to the first control unit 302.

[0169] The first control unit 302 is also used to acquire a first voltage through the connection channel between the third terminal 304c of the first switch unit 304 and the first control unit 302; when the first control unit 302 controls the first switch unit 304 to open and the first voltage is greater than 0, the first control unit 302 is also used to determine that the first switch unit 304 is faulty.

[0170] It is understandable that the first voltage collected through the connection channel between the third terminal 304c of the first switch unit 304 and the first control unit 302 can be used to detect whether the first switch unit 304 is faulty. If the first voltage is greater than 0, it means that the first switch unit 304 cannot be disconnected normally, so the fault of the first switch unit 304 can be reported in time to ensure the reliability of the power supply system.

[0171] Optionally, the first voltage is a high-side drive (HSD) sampling voltage, and the acquisition of the first voltage requires the first control unit 302 to have the capability of high-side drive voltage sampling.

[0172] In one possible embodiment, if the communication abnormality duration between the first control unit 302 and the first power distribution unit 303 exceeds a third threshold, the first control unit 302 is further configured to control the first power distribution unit 303 to shut down power distribution and / or control the first switch unit 304 to disconnect.

[0173] Understandably, it is possible to verify whether the communication between the first power distribution unit 303 and the first control unit 302 is normal, so that in case of abnormality, the first power distribution unit 303 can be controlled to shut down the power distribution and / or the first switch unit 304 can be controlled to disconnect, so as to stop the power supply to the first motor in time and ensure the reliability of the power supply system.

[0174] Optionally, an abnormal communication between the first control unit 302 and the first power distribution unit 303 may refer to an interruption in communication between the first control unit 302 and the first power distribution unit 303, or it may refer to an abnormal situation where the communication between the first control unit 302 and the first power distribution unit 303 is not interrupted, but the signal in the communication is lost or invalid. This application embodiment does not limit this.

[0175] Optionally, the third threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0176] In one possible embodiment, if the duration of continuous operation of the first power distribution unit 303 exceeds a fourth threshold and / or the first control unit 302 malfunctions, the first power distribution unit 303 shuts down power distribution.

[0177] It is understandable that the first power distribution unit 303 is equipped with control logic for continuous operation time, so that the power distribution is shut off after the first power distribution unit 303 has been working continuously for a certain period of time, and / or, when the first control unit 302 fails, the first power distribution unit 303 shuts off the power distribution, promptly stops supplying power to the first motor, and ensures the reliability of the power supply system.

[0178] Optionally, the fourth threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0179] In one possible embodiment, the power supply device 30 further includes a second switching unit 305.

[0180] For details, please refer to [link / reference]. Figure 5 , Figure 5 This is a schematic diagram of another power supply device provided in an embodiment of this application.

[0181] The second switch unit 305 is connected in series with the first switch unit 304.

[0182] Optionally, the first terminal 305a of the second switching unit 305 is connected to the second terminal 303b of the first power distribution unit 303, the second terminal 305b of the second switching unit 305 is connected to the first terminal 304a of the first switching unit 304, the third terminal 305c of the second switching unit 305 is connected to the first control unit 302, and the fourth terminal of the second switching unit 305 is grounded.

[0183] The first control unit 302 is used to control the closing of the second switch unit 305.

[0184] It is understood that the first control unit 302 controls the second switch unit 305 in the power supply device 30 to close, and jointly controls the first switch unit 304 in the power supply device 30 to close and the first power distribution unit 303 to open the power distribution, so as to supply power to the first motor.

[0185] It is understandable that the first control unit 302 jointly controls the first switch unit 304, the first power distribution unit 303, and the second switch unit 305. Power can be supplied to the first motor only when the first switch unit 304 is closed, the second switch unit 305 is closed, and the first power distribution unit 303 is turned on. If any condition is not met, power will be stopped to the first motor. Therefore, it can avoid the loss of control over power supply to the first motor due to software and / or hardware failure of the first power distribution unit 303, thereby reducing the damage rate of the air pump motor compressor and improving reliability.

[0186] Optionally, the second switching unit 305 can be in a normally closed state, which has lower requirements for electrical life.

[0187] In one possible embodiment, if the first switch unit 304 is stuck and the first power distribution unit 303 fails to control, the first control unit 302 is used to control the second switch unit 305 to disconnect.

[0188] It is understandable that when the first switch unit 304 is stuck together and the first power distribution unit 303 fails to control, the power supply to the first motor can be cut off by controlling the second switch unit 305 to ensure the safety and reliability of the power supply system.

[0189] Optionally, in Figure 5 In the power supply device, the first switch unit 304 may have a sticking problem by collecting the first circuit current that supplies power to the first motor through the first power distribution unit 303, or by collecting the second circuit current that supplies power to the first motor through the connection channel between the first terminal 304a of the first switch unit 304 and the first control unit 302. This application embodiment does not limit this, and the specific implementation can be referred to the corresponding description above, which will not be repeated here.

[0190] It should be understood that the above Figures 3 to 5 The power supply device provided in this application is described illustratively only as several possible embodiments and should not be construed as limiting the application.

[0191] It should be understood that, based on the above Figures 3 to 5 All new embodiments obtained by reasonable modification, supplementation or combination fall within the protection scope of this application.

[0192] This application also provides a power supply control method, which can be found in the following embodiments. Figure 6 , Figure 6 This is a flowchart illustrating a power supply control method provided in an embodiment of this application. This power supply control method is applied in the field of electronic circuit technology, such as the power supply control of the air pump motor in a vehicle's air suspension system, and can be specifically applied to the aforementioned... Figures 3 to 5 Any one of the possible power supply devices.

[0193] Specifically, the power supply control method includes, but is not limited to, the following steps:

[0194] S601: The power supply control device controls the first switch unit in the power supply device to close and controls the first power distribution unit in the power supply device to open the power distribution, so as to realize the control of the power supply device to supply power to the first motor.

[0195] It is understood that the power supply control device in the embodiments of this application may be a device equipped with a processor / chip that can execute computer execution instructions, or it may be a processor / chip that can execute computer execution instructions. Optionally, the power supply control device may be an electronic device, or it may be a processor / chip within an electronic device, used to execute the power supply control method in the embodiments of this application to reduce the damage rate of the compressor of the air pump motor and improve reliability.

[0196] Optionally, the power supply control device and power supply control method in the embodiments of this application can be applied to, but are not limited to, vehicle systems. The vehicle equipped with the vehicle system is an intelligent driving vehicle and can be replaced by a terminal device. The terminal device can be, but is not limited to, vehicles such as commercial vehicles, passenger cars, trains, industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), robots, etc. The embodiments of this application do not specifically limit this.

[0197] It is understandable that by controlling the closing of the first switch unit and the opening of the first power distribution unit in the power supply device, power can be supplied to the first motor.

[0198] It is understandable that by jointly controlling the first switching unit and the first power distribution unit, power can be supplied to the first motor only when the first switching unit is closed and the first power distribution unit is turned on. If either condition is not met, power will be stopped to the first motor. Therefore, it can avoid the loss of control over power supply to the first motor due to software and / or hardware failure of the first power distribution unit, thereby reducing the damage rate of the air pump motor compressor and improving reliability.

[0199] In one possible embodiment, the timing of closing the first switching unit is before the timing of opening the first power distribution unit for power distribution.

[0200] Understandably, before controlling the first power distribution unit to start power distribution, it is necessary to control the first switch unit to close first. This can avoid the impact of inrush current and shutdown current on the first switch unit when a large current load is directly connected, and improve the electrical life of the first switch unit.

[0201] Optionally, since the first switching unit is actually under load after the load circuit stabilizes, the current specification of the first switching unit can be appropriately reduced to reduce costs and optimize noise, vibration, and harshness (NVH).

[0202] In one possible embodiment, the above power supply control method further includes:

[0203] The system acquires the operating time and / or temperature of the first motor; if the operating time of the first motor exceeds a first threshold and / or the temperature of the first motor exceeds a second threshold, the system controls the first power distribution unit to shut down the power distribution and / or controls the first switch unit to open.

[0204] Understandably, by jointly controlling the first switching unit and the first power distribution unit, power supply to the first motor can be stopped when the first switching unit is disconnected and / or the first power distribution unit shuts off power distribution. Utilizing dual-path control of the first switching unit and the first power distribution unit can prevent uncontrolled power supply to the first motor due to software and / or hardware failure of the first power distribution unit, thereby reducing the compressor damage rate of the air pump motor and improving reliability.

[0205] Optionally, the first threshold and the second threshold are not fixed values ​​and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0206] In one possible embodiment, the above power supply control method further includes:

[0207] If adhesion is detected in the first switching unit, the first power distribution unit is controlled to shut down the power distribution.

[0208] Understandably, when the first switch unit is detected to be stuck, the power supply to the first motor can be stopped by controlling the first power distribution unit to shut down the power distribution. By using the dual control of the first switch unit and the first power distribution unit, the loss of control over the power supply to the first motor caused by the sticking of the first switch unit can be avoided, thereby reducing the damage rate of the compressor of the air pump motor and improving reliability.

[0209] Optionally, the first switch unit is stuck together, which can be understood as the fixed contact and the movable contact of the first switch unit melting and welding together, thus making it impossible to control the disconnection normally.

[0210] In one possible embodiment, the above power supply control method further includes:

[0211] The first switch unit is controlled to disconnect and the first power distribution unit is controlled to start power distribution; if the first circuit current supplying power to the first motor is greater than 0 when the first power distribution unit collects data, it is determined that the first switch unit is stuck.

[0212] Understandably, the first switching unit can detect potential sticking problems by collecting the first circuit current that supplies power to the first motor through the first power distribution unit, thereby allowing for timely shutdown of power supply to the first motor and ensuring the reliability of the power supply system.

[0213] In one possible embodiment, the above power supply control method further includes:

[0214] The system controls the first switching unit to disconnect and the first power distribution unit to start power distribution; it collects the second circuit current supplying power to the first motor through the connection channel between the first switching unit and the first control unit in the power supply device; and it determines that the first switching unit is stuck when the second circuit current is greater than 0.

[0215] It is understandable that the sticking problem of the first switch unit can be detected by collecting the second circuit current that supplies power to the first motor through the connection channel between the first switch unit and the first control unit. This allows for timely cessation of power supply to the first motor and avoids the failure of the first power distribution unit's current acquisition or network communication failure, which could prevent the timely detection of the sticking problem of the first switch unit. This ensures the reliability of the power supply system.

[0216] In one possible embodiment, the above power supply control method further includes:

[0217] The first switching unit is disconnected; a first voltage is collected through the connection channel between the first switching unit and the first control unit in the power supply device; if the first voltage is greater than 0, the first switching unit is determined to be faulty.

[0218] It is understandable that the first voltage collected through the connection channel between the first switching unit and the first control unit can be used to detect whether the first switching unit is faulty. If the first voltage is greater than 0, it means that the first switching unit cannot disconnect normally, so the fault of the first switching unit can be reported in time to ensure the reliability of the power supply system.

[0219] In one possible embodiment, the above power supply control method further includes:

[0220] The duration of communication disconnection between the first control unit and the first power distribution unit in the power supply device is obtained; if the abnormal communication duration between the first control unit and the first power distribution unit exceeds a third threshold, the first power distribution unit is controlled to shut down power distribution and / or the first switching unit is controlled to disconnect.

[0221] Understandably, it is possible to verify whether the communication between the first power distribution unit and the first control unit is normal, so that in case of abnormality, the first power distribution unit can be controlled to shut down power distribution and / or the first switching unit can be controlled to disconnect, so as to stop power supply to the first motor in time and ensure the reliability of the power supply system.

[0222] Optionally, the third threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0223] In one possible embodiment, the above power supply control method further includes:

[0224] The system obtains the duration of continuous operation of the first power distribution unit and / or the operating status of the first control unit in the power supply device; if the duration of continuous operation of the first power distribution unit exceeds the fourth threshold and / or the first control unit malfunctions, the system controls the first power distribution unit to shut down power distribution.

[0225] It is understandable that control logic is set for the continuous working time of the first power distribution unit, which controls the power distribution to be shut down after the first power distribution unit has been working continuously for a certain period of time, and / or controls the first power distribution unit to shut down the power distribution when the first control unit fails, so as to stop supplying power to the first motor in a timely manner and ensure the reliability of the power supply system.

[0226] Optionally, the fourth threshold is not a fixed value and can be adjusted according to different application scenarios. This application embodiment does not impose any restrictions on this.

[0227] In one possible embodiment, the above power supply control method further includes:

[0228] The second switch unit in the control power supply device is closed.

[0229] It is understood that the closing of the second switch unit in the control power supply device, in conjunction with the closing of the first switch unit and the activation of the first power distribution unit, enables power to be supplied to the first motor. It is also understood that by jointly controlling the first switch unit, the first power distribution unit, and the second switch unit, power can only be supplied to the first motor when both the first and second switch units are closed and the first power distribution unit is activated. If any condition is not met, power supply to the first motor will cease. Therefore, this avoids uncontrolled power supply to the first motor due to software and / or hardware failure of the first power distribution unit, thereby reducing the compressor damage rate of the air pump motor and improving reliability.

[0230] Optionally, the second switching unit can be in a normally closed state, which has lower requirements for electrical life.

[0231] In one possible embodiment, the above power supply control method further includes:

[0232] If the first switch unit is found to be stuck together and the first power distribution unit fails to control, the second switch unit is controlled to disconnect.

[0233] It is understandable that when the first switch unit is stuck together and the first power distribution unit fails to control, the power supply to the first motor can be cut off by controlling the second switch unit to disconnect, thus ensuring the safety and reliability of the power supply system.

[0234] The methods of the embodiments of this application have been described in detail above. The following provides an apparatus for implementing any one of the methods in the embodiments of this application. For example, an apparatus is provided that includes a unit (or means) for implementing the steps performed by the device in any of the above methods.

[0235] Please see Figure 7 , Figure 7 This is a schematic diagram of a power supply control device provided in an embodiment of this application.
