Description

Technical Field

[0001] This invention relates to the field of power management technology, and in particular to a power management method, apparatus, device, storage medium, and product. Background Technology

[0002] Traditional power management solutions in new energy vehicles involve numerous ECUs (Electronic Control Units), all of which require power. If only one area of ​​the vehicle's low-voltage battery manages the electronic controllers, it could lead to a complete depletion of the low-voltage battery. In other words, if a faulty ECU causes excessive static current consumption, it could cause all low-voltage controllers in the vehicle to malfunction.

[0003] The entire solution described above has only one local functional group. When a certain controller malfunctions, it will cause a low-voltage power supply abnormality in the entire vehicle, which may lead to a power outage of the vehicle's battery.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main objective of this invention is to provide a power management method, apparatus, device, storage medium, and product, aiming to solve the technical problem that if the electronic controller is managed from only one area point of the vehicle's low-voltage battery, it may lead to the depletion of the vehicle's low-voltage battery.

[0006] To achieve the above objectives, the present invention proposes a power management method, the method comprising:

[0007] Obtain the function type of each electronic controller within the set of electronic controllers for power management;

[0008] Based on the function type, each electronic controller in the electronic controller set is assigned to a corresponding local function group;

[0009] Connect each of the aforementioned local functional groups to the corresponding low-voltage power supply;

[0010] The corresponding local functional group is powered by the low-voltage power supply.

[0011] In one embodiment, the step of assigning each electronic controller within the electronic controller set to a corresponding local functional group according to the function type includes:

[0012] Based on the function type, determine the electronic controllers within the electronic controller set that are used to perform the same function;

[0013] The electronic controllers used to perform the same function are divided into corresponding local function groups.

[0014] In one embodiment, before the step of connecting each of the local functional groups to the corresponding low-voltage power supply, the method further includes:

[0015] The required low-voltage power supply capacity for each of the aforementioned local functional groups is determined based on the functional type corresponding to each of the aforementioned local functional groups;

[0016] The batteries are divided according to the capacity of the low-voltage power supply required by each of the aforementioned local functional groups, thereby obtaining the low-voltage power supply corresponding to each of the aforementioned local functional groups.

[0017] In one embodiment, the step of determining the required low-voltage power supply capacity for each local functional group based on the functional type corresponding to each local functional group includes:

[0018] The weight ratio of electronic controllers, the sleep power consumption of electronic controllers, the network segment to which electronic controllers belong, the connection load of electronic controllers, and the number of electronic controllers are determined according to the function type corresponding to each local functional group.

[0019] The power consumption of the local functional group is determined based on the weight ratio of the electronic controller, the power consumption of the electronic controller during sleep, the network segment to which the electronic controller belongs, the connection load of the electronic controller, and the number of electronic controllers.

[0020] The required low-voltage power supply capacity for the local functional group is determined based on the power consumption.

[0021] In one embodiment, the step of supplying power to the corresponding local functional group via the low-voltage power supply includes:

[0022] Power-on anomaly detection is performed based on the electronic controller of the aforementioned local functional group;

[0023] When an electronic controller malfunction is detected, the low-voltage power supply corresponding to the local functional group to which the electronic controller malfunction belongs is stopped.

[0024] In one embodiment, after the step of managing the corresponding low-voltage power supply through the local function group, the following steps are included:

[0025] When the low-voltage power supply is controlled to stop working, a power-off signal is received from the low-voltage power supply.

[0026] Based on the power failure signal, locate the faulty electronic controller.

[0027] Furthermore, to achieve the above objectives, the present invention also proposes a power management device, the power management device comprising:

[0028] The detection module is used to obtain the functional type of each electronic controller in the power management electronic controller set;

[0029] The control module is used to divide each electronic controller in the electronic controller set into a corresponding local function group according to the function type;

[0030] A connection module is used to connect each of the local functional groups to the corresponding low-voltage power supply.

[0031] An execution module is used to supply power to the corresponding local functional group via the low-voltage power supply.

[0032] Furthermore, to achieve the above objectives, the present invention also proposes a power management device, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the power management method as described above.

[0033] In addition, to achieve the above objectives, the present invention also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the power management method described above.

[0034] In addition, to achieve the above objectives, the present invention also provides a computer program product, the computer program product comprising a computer program, which, when executed by a processor, implements the steps of the power management method as described above.

[0035] One or more technical solutions proposed in this invention have at least the following technical effects:

[0036] This invention obtains the functional types of each electronic controller within a power management electronic controller set; divides each electronic controller within the set into corresponding local functional groups according to the functional types; connects each local functional group to a corresponding low-voltage power supply; and supplies power to the corresponding local functional group through the low-voltage power supply. Because this invention divides all electronic controllers participating in low-voltage power management according to functional areas, and implements regional power management throughout the vehicle, the nodes participating in power management can be divided into multiple local functional groups. Furthermore, the low-voltage power supplies involved in power supply operate independently without affecting each other. Therefore, once a power failure signal is received from the low-voltage power supply, the faulty electronic controller can be quickly located. Compared with existing technologies, this invention prevents a situation where a large static current consumption due to a fault in a single electronic controller causes all low-voltage controllers in the vehicle to malfunction.

[0043] Figure 5 This is a schematic diagram of the device structure of the hardware operating environment involved in the power management method in this embodiment of the invention.

[0044] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of the present invention and are not intended to limit the present invention.

[0046] To better understand the technical solution of the present invention, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0047] The main solution of this invention is: to obtain the function type of each electronic controller in the power management electronic controller set; to divide each electronic controller in the electronic controller set into a corresponding local function group according to the function type; to connect each local function group to a corresponding low-voltage power supply; and to supply power to the corresponding local function group through the low-voltage power supply.

[0048] In this embodiment, for ease of description, the following description will focus on identifying the power controller as the executing entity.

[0049] In existing technologies, if the vehicle's low-voltage battery is managed by an electronic controller in only one area, it may lead to the vehicle's low-voltage battery being depleted. In other words, if a certain ECU has a large static current consumption due to its own fault, it will cause all low-voltage controllers in the vehicle to malfunction.

[0050] This invention provides a solution that divides all electronic controllers involved in low-voltage power management into functional areas. By dividing these areas according to the functions of the electronic controllers, regional power management is implemented throughout the vehicle. The nodes involved in power management can be divided into multiple local functional groups, and the low-voltage power supplies operating independently do not interfere with each other. Therefore, once a power failure signal is received from the low-voltage power supply, the faulty electronic controller can be quickly located. Compared with existing technologies, this invention prevents a situation where a fault in one electronic controller leads to high static current consumption, without causing all low-voltage controllers in the vehicle to malfunction.

[0051] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions. The following description uses a power controller as an example to illustrate this embodiment and the subsequent embodiments.

[0052] Based on this, embodiments of the present invention provide a power management method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the power management method of the present invention.

[0053] In this embodiment, the power management method includes steps S10 to S40:

[0054] Step S10: Obtain the function type of each electronic controller in the power management electronic controller set.

[0055] It should be noted that the above-mentioned electronic controller can be a Bluetooth key DKM, or a left vehicle domain controller VIUL, etc., and this embodiment does not limit it;

[0056] It should be noted that the above-mentioned function type can be a vehicle unlocking function, or a low-voltage to high-voltage conversion function for vehicle equipment, etc. This embodiment does not limit this.

[0057] It is understandable that the electronic controllers and functional types mentioned above are different in different power management schemes.

[0058] In practice, there are many electronic controllers involved in power management, and each electronic controller performs different functions. Some electronic controllers can complete tasks independently, while others need to work together with other electronic controllers to complete tasks. Therefore, it is necessary to first obtain the function type of each electronic controller in the entire set of electronic controllers involved in power management in the vehicle.

[0059] Step S20: Divide each electronic controller in the electronic controller set into a corresponding local function group according to the function type.

[0060] It should be noted that the aforementioned local functional groups can be active local functional groups or passive local functional groups, etc., and this embodiment does not impose any restrictions on them.

[0061] Understandably, the aforementioned local functional groups differ in different power management schemes.

[0062] In a specific implementation, the various electronic controllers in the electronic controller set are divided according to the above-mentioned function types, and the resistor controllers with the same function type are grouped into the same local function group. It should be noted that the number of the local function groups depends on the actual function type.

[0063] Step S30: Connect each of the local functional groups to the corresponding low-voltage power supply.

[0064] It should be noted that the aforementioned low-voltage power source can be a storage battery.

[0065] It is understandable that the number and capacity of the aforementioned low-voltage power supplies differ in different power management schemes.

[0066] In a specific implementation, the battery inside the vehicle is divided into multiple low-voltage power supplies corresponding to the number of the aforementioned local functional groups by means of segmentation, and the aforementioned local functional groups are connected to the corresponding low-voltage power supplies.

[0067] Step S40: Power is supplied to the corresponding local functional group through the low-voltage power supply.

[0068] In practical implementation, when it is detected that the vehicle needs to perform work on a certain module, the corresponding local functional group is powered by the aforementioned low-voltage power supply. If there is an abnormal electronic controller in the aforementioned local functional group, a power-off signal is received from the aforementioned low-voltage power supply. At this time, the faulty electronic controller can be quickly located based on the feedback power-off signal from the aforementioned low-voltage power supply. This embodiment provides a power management method, which obtains the function type of each electronic controller in the set of electronic controllers under power management; divides each electronic controller in the set of electronic controllers into a corresponding local functional group according to the function type; connects each local functional group to a corresponding low-voltage power supply; and powers the corresponding local functional group through the low-voltage power supply. Therefore, compared with the prior art, the present invention does not cause a situation where all low-voltage controllers in the vehicle fail to work even if a certain electronic controller has a large static current consumption due to its own failure.

[0069] Based on the first embodiment of the present invention, in the second embodiment of the present invention, the same or similar content as in the first embodiment can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of the power management method of the present invention.

[0070] In this embodiment, step S20 includes steps S201 to S202:

[0071] Step S201: Determine the electronic controllers in the electronic controller set that are used to perform the same function according to the function type.

[0072] It should be noted that the same function mentioned above can be the vehicle locking and unlocking function, or the DC-DC normal working function, etc. This embodiment does not limit it.

[0073] Understandably, the same function described above will differ across different power management schemes.

[0074] In a specific implementation, this embodiment takes the vehicle locking and unlocking function and the DCDC normal operation function as examples. The electronic controller that realizes the vehicle locking and unlocking function includes at least the Bluetooth key DKM and the left body domain controller VIUL. The electronic controller that realizes the DCDC normal operation function includes at least the power domain controller PDCU, the power battery management controller BMS, the left body domain controller VIUL, and the DC to DC controller DCDC.

[0075] Step S202: The electronic controllers used to perform the same function are assigned to corresponding local function groups.

[0076] In the specific implementation, the electronic controllers that enable the vehicle to unlock after locking are assigned to the first and second partial function groups, the left body domain controller VIUL is assigned to the first, second and third partial function groups, and the electronic controllers that enable the DC-DC converter to work normally are assigned to the fourth and fifth partial function groups.

[0077] In one possible implementation, steps S31' to S32' may be included before step S30:

[0078] Step S31': Determine the required low-voltage power supply capacity for each local functional group based on the functional type corresponding to each local functional group.

[0079] In a specific implementation, this embodiment takes the vehicle locking and unlocking function and the normal operation function of DCDC as examples. The capacity of the low-voltage power supply is determined according to the function type corresponding to the first local function group, the second local function group, the third local function group, the fourth local function group and the fifth local function group.

[0080] Step S32': Divide the battery according to the capacity of the low-voltage power supply required by each of the local functional groups to obtain the low-voltage power supply corresponding to each of the local functional groups.

[0081] In a specific implementation, the battery is divided into segments based on the capacity of the low-voltage power supplies in the first, second, third, fourth, and fifth local functional groups, resulting in a first low-voltage power supply, a second low-voltage power supply, a third low-voltage power supply, a fourth low-voltage power supply, and a fifth low-voltage power supply. It should be noted that the types and numbers of electronic controllers in the groups included in the first, second, third, fourth, and fifth local functional groups are specific to this embodiment and may differ in other power management schemes within a vehicle.

[0082] In one feasible implementation, steps S31' to S313' may be included after step S31':

[0083] Step S311': Determine the weight ratio of the electronic controller in each local functional group, the sleep power consumption of the electronic controller, the network segment to which the electronic controller belongs, the connected load of the electronic controller, and the number of electronic controllers according to the function type corresponding to each local functional group.

[0084] It should be noted that the above weight percentage can be the proportion of the computing space occupied by the above electronic controller;

[0085] It should be noted that the aforementioned power consumption during sleep mode can be the power consumed by the aforementioned electronic controller when it is not in operation;

[0086] It should be noted that the aforementioned network segment can refer to the IP address range of the aforementioned electronic controller;

[0087] It should be noted that the load connected above can be a device connected to the input terminal of the electronic controller or a device connected to the output terminal of the electronic controller, etc.

[0088] It is understandable that the weighting ratio, sleep power consumption, network segment, connected load, and quantity are all different in different power management schemes.

[0089] In this specific implementation, taking the vehicle locking and unlocking function and the normal operation function of DC-DC as examples, the weight ratio, sleep power consumption, network segment, connected load and quantity of the five electronic controllers (Bluetooth key DKM, left vehicle domain controller VIUL, power domain controller PDCU, power battery management controller BMS and DC-DC controller DCDC) are determined according to the first local function group, the second local function group, the third local function group, the fourth local function group and the fifth local function group.

[0090] Step 312': Determine the power consumption of the local functional group based on the weight ratio of the electronic controller, the power consumption of the electronic controller during sleep, the network segment to which the electronic controller belongs, the connected load of the electronic controller, and the number of electronic controllers.

[0091] It should be noted that the power consumption mentioned above can be the power consumption of the aforementioned local functional group in all states.

[0092] Understandably, the power consumption will vary depending on the specific power management scheme described above.

[0093] In specific implementation, this embodiment takes the vehicle locking and unlocking function and the normal operation function of DC-DC as examples. The power consumption of the first local function group, the second local function group, the third local function group, the fourth local function group and the fifth local function group are determined according to the weight ratio, sleep power consumption, network segment, connected load and quantity of the five electronic controllers: Bluetooth key DKM, left body domain controller VIUL, power domain controller PDCU, power battery management controller BMS and DC-DC controller.

[0094] Step S313': Determine the required low-voltage power supply capacity for the local functional group based on the power consumption.

[0095] In a specific implementation, this embodiment takes the vehicle locking and unlocking function and the normal operation function of DCDC as examples. The capacity of the low-voltage power supply of the first local function group, the second local function group, the third local function group, the fourth local function group and the fifth local function group is determined according to the power consumption.

[0096] Based on the second embodiment of the present invention, in the third embodiment of the present invention, the same or similar content as in the second embodiment can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 , Figure 3 This is a flowchart illustrating the third embodiment of the power management method of the present invention.

[0097] In this embodiment, step S40 includes steps S401 to S402:

[0098] Step S401: Power-on anomaly detection is performed based on the electronic controller of the local functional group.

[0099] It should be noted that the above-mentioned power-on anomaly detection can be either power-on reset or voltage monitoring.

[0100] In a specific implementation, this embodiment takes the vehicle locking and unlocking function and the normal operation function of DCDC as examples, and performs power-on abnormality detection on the resistor controllers in the first local function group, the second local function group, the third local function group, the fourth local function group and the fifth local function group.

[0101] Step S402: When an electronic controller malfunction is detected, the low-voltage power supply corresponding to the local functional group to which the electronic controller malfunction belongs is controlled to stop working.

[0102] In this specific implementation, taking the vehicle locking and unlocking function and the normal operation function of the DC-DC converter as examples, when an abnormality is detected in the Bluetooth key DKM, the first low-voltage power supply and the second low-voltage power supply are controlled to stop working. When an abnormality is detected in the left vehicle domain controller VIUL, the first low-voltage power supply, the second low-voltage power supply, the third low-voltage power supply, the fourth low-voltage power supply, and the fifth low-voltage power supply are controlled to stop working. When an abnormality is detected in the power domain controller PDCU, the fourth low-voltage power supply and the fifth low-voltage power supply are controlled to stop working. When an abnormality is detected in the power battery management controller BMS, the fourth low-voltage power supply and the fifth low-voltage power supply are controlled to stop working. When an abnormality is detected in the DC-DC converter DCDC, the fourth low-voltage power supply and the fifth low-voltage power supply are controlled to stop working.

[0103] In one possible implementation, steps S41' to S42' may be included before step S40:

[0104] Step S41': When controlling the low-voltage power supply to stop working, receive the power-off signal fed back by the low-voltage power supply.

[0105] In a specific implementation, this embodiment takes the vehicle locking and unlocking function and the normal operation function of the DC-DC converter as examples. When the first low-voltage power supply is controlled to stop working, a first power-off signal fed back by the first low-voltage power supply is received; when the second low-voltage power supply is controlled to stop working, a second power-off signal fed back by the second low-voltage power supply is received; when the third low-voltage power supply is controlled to stop working, a third power-off signal fed back by the third low-voltage power supply is received; when the fourth low-voltage power supply is controlled to stop working, a fourth power-off signal fed back by the fourth low-voltage power supply is received; and when the fifth low-voltage power supply is controlled to stop working, a fifth power-off signal fed back by the fifth low-voltage power supply is received.

[0106] Step S42': Locate the faulty electronic controller based on the power failure signal.

[0107] In this specific implementation, taking the vehicle locking and unlocking function and the normal operation function of DCDC as examples, the fault resistor controller is located in the first local function group according to the first power failure signal; the fault resistor controller is located in the second local function group according to the second power failure signal; the fault resistor controller is located in the third local function group according to the third power failure signal; the fault resistor controller is located in the fourth local function group according to the fourth power failure signal; and the fault resistor controller is located in the fifth local function group according to the fifth power failure signal.
