Once the actual torque feedback of any driving component in the driving system is abnormal, that is, if the actual torque output by the component is inconsistent with the actual torque feedback by the component, the torque chain monitoring and torque chain verification of the whole vehicle controller module will consider that the whole vehicle system is running normally, while the real driving system is still abnormally outputting, which leads to the failure of the whole torque chain control and causes a serious safety accident.

[0025] According to the above technical solution, by monitoring the energy of the energy source system and the energy consuming system of the automobile in real time, the first source energy and the first consumed energy are obtained respectively; based on the first source energy and the first consumed energy, the energy consuming system is controlled to perform different operations, wherein the energy source system includes a battery pack and a power generation system, and the energy consuming system includes a driving system and a high-voltage accessory system, which realizes monitoring the vehicle running state by monitoring the sum of all input energies of the vehicle, i.e., the sum of the input energies of the battery pack and the power generation system, and the sum of all consumed energies of the vehicle, i.e., the consumed energies of the driving system and the high-voltage accessory system, and gets rid of the problem that the actual torque response is highly dependent on the traditional torque chain monitoring method.

[0026] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. 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 comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0027] According to a first aspect of the present invention, an energy management control method for assisting torque runaway is proposed. Figure 1 A schematic flowchart of an energy management control method 100 for assisting torque runaway according to an embodiment of the present invention is shown. Figure 1 As shown, method 100 may include the following steps.

[0028] Step S110: Monitor the energy of the vehicle's energy source system and energy consumption system in real time to obtain the first source energy and the first consumed energy, respectively.

[0029] Specifically, the first source energy is the sum of all energy input by all components in the energy source system to ensure the operation of the entire vehicle system; the first consumed energy is the sum of all energy consumed in the energy consumption system to drive the normal operation of the vehicle's functional components.

[0030] Step S120: Based on the first source energy and the first consumed energy, control the energy consumption system to perform different operations, wherein the energy source system includes a battery pack and a power generation system, and the energy consumption system includes a drive system and a high-voltage accessory system.

[0031] For example, the energy from the first source can be represented by E0. 源1 E1 indicates that the energy generated by the discharge of the battery pack in the energy source system can be represented as E1. 源 This indicates that the energy generated by the power generation system in the energy source system can be represented by E2. 源 It indicates that E0 源1 =E1 源 +E2 源 The first energy consumption can be achieved using E0. 耗1represents; the energy consumed by the drive system can be denoted as E1 耗1 represents; the energy consumed by the high-voltage accessory system can be denoted as E2 耗1 represents, wherein E0 耗1 = E1 耗1 + E2 耗1 Specifically, the high-voltage accessory system can be a collection of functional components inside the automobile that rely on high-voltage driving, such as air conditioning, etc.

[0032] The energy management control method for assisting in torque runaway provided in the present application monitors the energy of the energy source system and the energy consumption system of the automobile in real time to obtain first source energy and first consumption energy, respectively, controls the energy consumption system to perform different operations based on the first source energy and the first consumption energy, wherein the energy source system includes a battery pack and a power generation system, and the energy consumption system includes a drive system and a high-voltage accessory system, and the vehicle running state is monitored by monitoring the sum of all input energies of the vehicle running, i.e., the sum of the input energies of the battery pack and the power generation system, and the sum of all consumption energies of the vehicle running, i.e., the sum of the consumption energies of the drive system and the high-voltage accessory system, thereby solving the problem that the actual torque response is highly dependent on the method of relying on traditional torque chain monitoring.

[0033] Figure 2 A schematic flowchart of step S120 of controlling the energy consumption system to perform different operations based on the first source energy and the first consumption energy according to an embodiment of the present application is shown. As shown in Figure 2 Step S120 can include the following steps.

[0034] Step S121, taking the absolute value of the difference between the first source energy and the first consumption energy to obtain a first energy difference.

[0035] Specifically, the first energy difference can be denoted as |E0 源1 -E0 耗1 | represents.

[0036] Step S122, comparing the first energy difference with a preset first threshold value, and for the case that the first energy difference is greater than or equal to the preset first threshold value, controlling the high-voltage accessory system to be completely turned off, and continuously monitoring the energy of the energy source system and the energy consumption system in real time to obtain second source energy and second consumption energy, respectively.

[0037] Specifically, the preset first threshold value can be denoted as E1, and the preset first threshold value E1 can be set according to the related parameters of the high-voltage accessory system, which is not additionally limited herein. In |E0 源1 -E0 耗1When E1 is greater than or equal to E1, the system can control the shutdown of all functional components inside the vehicle that rely on high-voltage drives, such as the air conditioning. After the system has controlled the shutdown of all high-voltage accessory systems, it can again monitor the total energy input to the battery pack and the generator system, i.e., the second source energy; and the energy consumed by the drive system, i.e., the second consumed energy. At this time, the second source energy can be represented by E0. 源2 This means that the second energy consumption can be represented by E0_consumption2.

[0038] The above method obtains a first energy difference by taking the absolute value of the difference between the first source energy and the first consumed energy. This first energy difference is then compared to a preset first threshold. If the first energy difference is greater than or equal to the preset first threshold, the high-voltage accessory system is completely shut down. Simultaneously, the energy of the energy source system and the energy consumption system are continuously monitored in real time to obtain the second source energy and the second consumed energy, respectively. The absolute value of the difference between the source energy and the consumed energy is compared to the preset first threshold. If the absolute value is greater than or equal to the preset first threshold (i.e., the difference exceeds a preset range), the high-voltage accessory system is completely shut down. The second source energy and the second consumed energy are then monitored after the high-voltage accessory system is shut down. This method enables the determination of whether the vehicle's torque energy is abnormal based on the difference between the source energy and the consumed energy. If an abnormality in the vehicle's torque energy is determined, the consumed energy is downgraded to further monitor the overall vehicle torque energy situation.

[0039] Figure 3 A schematic flowchart illustrating step S120 of another embodiment of the present invention is shown: controlling the energy consumption system to perform different operations based on the first source energy and the first consumed energy. Figure 3 As shown, step S120 may include the following steps.

[0040] Step S123: Take the absolute value of the difference between the second source energy and the second consumed energy to obtain the second energy difference value.

[0041] For example, the energy from the second source can be represented by E0. 源2 This means that the second energy consumption can be represented by E0. 耗2 The second energy difference can be represented by |E0. 源2 -E0 耗2 | indicates.

[0042] Step S124: Compare the second energy difference with a preset second threshold. If the second energy difference is greater than or equal to the preset second threshold, control the drive system to perform a function degradation. At the same time, continuously monitor the energy of the energy source system and the energy consumption system in real time to obtain the third source energy and the third consumed energy respectively. The preset second threshold is less than the preset first threshold.

[0043] Exemplarily, the preset second threshold value can be denoted as E2, which can be set according to the parameters of the driving system of the motor, and is not additionally limited herein. When |E0 源2 -E0 耗2 When greater than or equal to the preset second threshold value E2, that is, when the difference between the total sum of the input energy of the vehicle and the total sum of the output energy of the vehicle is greater than or equal to the preset second threshold value E2, the driving system is controlled to perform function degradation, and specifically, the function degradation of the driving system can be realized by reducing the speed of the vehicle. Preferably, the operation of degrading the function of the driving system needs to last for a certain period of time to ensure that all the driving system function degradation is completed, and the vehicle enters a certain basic safety state. After the function degradation of the driving system is completed, the energy of the energy source system and the energy consumption system is monitored in real time, and the third source energy and the third consumption energy are obtained. Specifically, the third source energy can be denoted as E0 源3 , and the third consumption energy can be denoted as E0 耗3 .

[0044] The above method obtains the second energy difference value by taking the absolute value of the difference between the second source energy and the second consumption energy, compares the second energy difference value with the preset second threshold value, controls the driving system to perform function degradation in the case that the second energy difference value is greater than or equal to the preset second threshold value, and simultaneously continuously monitors the energy of the energy source system and the energy consumption system to obtain the third source energy and the third consumption energy, respectively. In this way, the preset second threshold value is smaller than the preset first threshold value, which realizes that when the difference between the total sum of the input energy of the vehicle and the total sum of the output energy of the vehicle is still equal to or greater than the preset second threshold value E2 after the high-voltage accessory system is turned off, the function degradation of the driving system is controlled again to further degrade the energy consumption of the vehicle, and the third source energy and the third consumption energy at this time are monitored to further monitor the torque energy of the vehicle, thereby avoiding the problem that the traditional torque chain monitoring method has a large dependence on the actual torque response.

[0045] Optionally, based on the first source energy and the first consumption energy, the energy consumption system is controlled to perform different operations, which further includes: taking the absolute value of the difference between the third source energy and the third consumption energy to obtain a third energy difference value; comparing the third energy difference value with a preset third threshold value, and controlling the driving system to be turned off in the case that the third energy difference value is greater than or equal to the preset third threshold value, wherein the preset third threshold value is greater than the preset second threshold value.

[0046] Exemplarily, the third source energy can be denoted as E0 源3 , the third consumption energy can be denoted as E0 耗3 , and the third energy difference value can be denoted as |E0 源3 -E0 耗3| represents, the preset third threshold value can be represented by E3, in |E0 源3 -E0 耗3 | greater than or equal to E3, control the drive system to close to ensure zero torque output, so that the vehicle enters a safe state.

[0047] The above method, by the third source energy and the third consumption energy difference after taking absolute value, to obtain the third energy difference; The third energy difference and the preset third threshold value are compared, and for the case that the third energy difference is greater than or equal to the preset third threshold value, the drive system is controlled to close, wherein the preset third threshold value is greater than the preset second threshold value, the difference between the sum of the total input energy of the vehicle and the sum of the total output energy of the vehicle is still equal to or greater than the preset third threshold value E3, which determines the abnormal torque driving condition of the vehicle, controls the drive system to close, so that the vehicle enters a safe state, and the safety of the vehicle system is ensured.

[0048] Figure 4 A schematic flow chart of an energy management control method 400 for assisting torque out of control according to another embodiment of the application is shown. As shown, the method 400 can include the following steps. Figure 4

[0049] Step S410, the preliminary determination is made for the power generation system and / or the drive system to determine whether the power generation system and / or the drive system has torque abnormality.

[0050] Specifically, whether there is torque abnormality can be determined by comparing whether the electrical output of the power generation system and the mechanical output of the drive system are consistent.

[0051] Step S420, for the case that the power generation system and / or the drive system has torque abnormality, the energy consumption system is controlled to perform different operations.

[0052] Specifically, when it is determined that the power generation system and / or the drive system has torque abnormality, the opening / closing of the vehicle functional components can be controlled to realize function degradation, and then different control of the energy consumption system is realized.

[0053] Step S430, for the case that the power generation system and / or the drive system does not have torque abnormality, the energy of the energy source system and the energy consumption system is continuously monitored in real time.

[0054] ​The method determines whether the torque of the power generation system and / or the driving system is abnormal by preliminarily judging the power generation system and / or the driving system, and controls the energy consumption system to perform different operations in the case that the torque of the power generation system and / or the driving system is abnormal, so that the safety of the vehicle is improved.

[0055] It can be understood that the steps S420 and S430 do not have a sequence of execution, and are only different execution steps of whether the torque is abnormal.

[0056] Optionally, the preliminarily judging the power generation system and / or the driving system to determine whether the torque of the power generation system and / or the driving system is abnormal comprises: calculating the electrical output energy and the mechanical output energy of the power generation system; comparing whether the electrical output energy and the mechanical output energy are consistent, and determining that the torque of the power generation system is not abnormal in the case that the electrical output energy and the mechanical output energy are consistent, and determining that the torque of the power generation system is abnormal in the case that the electrical output energy and the mechanical output energy are inconsistent; and / or calculating the electrical consumption energy and the mechanical consumption energy of the driving system; comparing whether the electrical consumption energy and the mechanical consumption energy are consistent, and determining that the torque of the driving system is not abnormal in the case that the electrical consumption energy and the mechanical consumption energy are consistent, and determining that the torque of the driving system is abnormal in the case that the electrical consumption energy and the mechanical consumption energy are inconsistent.

[0057] For example, in the case that the electrical output energy and the mechanical output energy of the power generation system are consistent, it is determined that the torque of the power generation system is not abnormal, and the electrical output energy and the mechanical output energy of the power generation system can be continuously monitored to ensure the safety of the vehicle; in the case that the electrical output energy and the mechanical output energy of the power generation system are inconsistent, i.e., the torque is abnormal, it can be used as a starting condition for controlling the energy consumption system to perform different operations, and the energy consumption system is controlled to perform corresponding operations in a corresponding manner according to the foregoing description. In the case that the electrical consumption energy and the mechanical consumption energy of the driving system are consistent, it is determined that the torque of the driving system is not abnormal, and the electrical consumption energy and the mechanical consumption energy of the driving system can be continuously monitored to ensure the safety of the vehicle; in the case that the electrical consumption energy and the mechanical consumption energy of the driving system are inconsistent, it can also be used as a starting condition for controlling the energy consumption system to perform different operations, and the energy consumption system is controlled to perform corresponding operations in a corresponding manner according to the foregoing description.

[0058] The method compares the electrical output energy and the mechanical output energy of the power generation system to determine whether the power generation system has torque abnormality, and / or calculates the electrical consumption energy and the mechanical consumption energy of the driving system, compares the electrical consumption energy and the mechanical consumption energy to determine whether the driving system has torque abnormality, thereby judging whether the vehicle has torque abnormality by monitoring the electrical output energy and the mechanical output energy of the power generation system and / or the electrical consumption energy and the mechanical consumption energy of the driving system, saving time wasted due to the complex process of torque abnormality judgment, improving the accuracy of energy management monitoring, improving the safety of vehicle operation, and solving the problem of high dependence of traditional torque chain monitoring method on actual torque response.

[0059] Optionally, the electrical output energy and the mechanical output energy of the power generation system are calculated by the following formula: wherein, E 源 represents the electrical output energy, u represents the bus voltage of the power generation system, i represents the bus current of the power generation system, E′ 源 represents the mechanical output energy, T represents the actual output torque of the power generation system, and n represents the speed of the power generation system; the electrical consumption energy and the mechanical consumption energy are calculated by the following formula, including: wherein, E 耗 represents the electrical consumption energy, u represents the bus voltage of the driving system, i represents the bus current of the driving system, E′ 耗 represents the mechanical consumption energy, T represents the actual output torque of the driving system, and n represents the speed of the driving system.

[0060] For example, when E 源 =E′ 源 , the electrical output energy and the mechanical output energy of the power generation system can be continuously monitored to ensure the safety of vehicle operation; when E 源 ≠E′ 源 , the energy consumption system can be controlled to perform corresponding operation in a corresponding manner. When E 耗 =E′ 耗 , the electrical consumption energy and the mechanical consumption energy of the driving system can be continuously monitored to ensure the safety of vehicle operation; when E 耗 ≠E′ 耗 , the energy consumption system can be controlled to perform corresponding operation in a corresponding manner.

[0061] The method compares the electric output energy and the mechanical output energy of the power generation system to determine whether the torque of the power generation system is abnormal, and / or calculates the electric consumption energy and the mechanical consumption energy of the driving system, compares the electric consumption energy and the mechanical consumption energy, and determines that the torque of the driving system is abnormal when the electric consumption energy and the mechanical consumption energy are consistent, thereby accurately determining whether the torque of the vehicle is abnormal by monitoring the electric output energy and the mechanical output energy of the power generation system and / or the electric consumption energy and the mechanical consumption energy of the driving system, saving time wasted due to the complex process of torque abnormality determination, improving the safety of vehicle operation, and solving the problem that the actual torque response is highly dependent on the traditional torque chain monitoring method.

[0062] According to a second aspect of the present application, an energy management control device for assisting torque runaway is provided. Figure 5 A schematic block diagram of the energy management control device 500 for assisting torque runaway according to an embodiment of the present application is shown. As shown in the figure, Figure 5 The control device 500 can include an energy monitoring module 510 and a control module 520.

[0063] The energy monitoring module 510 is configured to monitor the energy of the energy source system and the energy consumption system of the vehicle in real time to obtain the first source energy and the first consumption energy, respectively.

[0064] The control module 520 is configured to control the energy consumption system to perform different operations based on the first source energy and the first consumption energy, wherein the energy source system includes a battery pack and a power generation system, and the energy consumption system includes a driving system and a high-voltage accessory system.

[0065] According to a third aspect of the present application, an electronic device is also provided. Figure 6 A schematic block diagram of the electronic device 600 according to an embodiment of the present application is shown. As shown in the figure, Figure 6 The electronic device 600 can include a processor 610 and a memory 620. The memory 620 stores computer program instructions, which are executed by the processor 610 to perform the energy management control method for assisting torque runaway as described above.
