[0065] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.
[0066] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment.

[0067] Hybrid vehicles are vehicles that can be powered by both batteries and fuel. As people become more aware of environmental protection, hybrid vehicles are becoming more and more popular. The driving modes of hybrid vehicles can be divided into pure electric, series and hybrid. Depending on different situations, hybrid vehicles can be driven by different power.
[0068] In the operation of hybrid vehicles, in order to protect the battery, the battery power needs to be controlled to avoid damage due to excessive discharge of the battery. Specifically, the hybrid vehicle detects the battery power during movement and changes the operation mode of the hybrid vehicle according to the battery power. Generally, when the battery power is sufficient, the operation mode of the hybrid vehicle is the charge depletion mode (CD); as the battery power is consumed, when the power drops to a certain threshold, the vehicle will switch to the charge sustaining mode (CS). When the vehicle is in the charge depletion mode, the hybrid vehicle mainly relies on the battery for power supply, and the motor is used to drive the vehicle first; when the battery power is sufficient, the vehicle can be driven only by the motor, thereby reducing dependence on fuel and achieving the purpose of energy saving and emission reduction. When the vehicle is in the charge sustaining mode, the engine and the motor work together. The engine can not only drive the vehicle forward, but also charge the battery by driving the generator, thereby maintaining the battery power state.
[0069] At present, when switching between CS / CD modes, a fixed power threshold is generally set in advance, and the sport mode to be used is determined by comparing the battery power with the power threshold, and the sport modes include CD and CS. The current method takes fewer factors into consideration, cannot make better use of the available battery space, and also causes the sport mode switching to be inaccurate.
[0070] Based on the above problems, the present application proposes a control method for a hybrid vehicle, which jointly determines a power threshold through the vehicle's driving mode and environmental information of the vehicle's environment, so that the power threshold changes with changes in the vehicle state and environment, and finally determines the vehicle's operating mode based on the battery power and the size of the power threshold, so that the final determined vehicle operating mode is more in line with the vehicle state and the current environment, thereby achieving the purpose of more accurate switching of the operating mode.
[0071] The following combination Figure 1 The control method of the hybrid vehicle of the embodiment of the present application is described in detail. The method of the present application can be implemented in a vehicle controller (HCU) of the vehicle, and of course the method of the present application can also be implemented in other electronic devices.
[0072] Figure 1 A schematic flow chart of a control method for a hybrid vehicle provided by the present application is shown, referring to Figure 1 , the method is described in detail as follows:
[0073] S101, obtaining the detected power of a battery detected by a battery management module in a vehicle.
[0074] In this embodiment, the battery management system (BMS) can intelligently manage and maintain the battery in the vehicle, and the BMS can also detect the battery power.
[0075] It should be noted that if the BMS does not output a power signal, the detected power is set to 0. When the HCU cannot receive a power signal sent by the BMS, the detected power is set to 0.
[0076] S102, correcting the detected power to determine a target battery power for determining an operation mode of the vehicle, wherein the operation mode includes a power consumption mode and a power retention mode.
[0077] In this embodiment, a correction coefficient may be preset, and the correction coefficient may be multiplied by the detected power to obtain the target battery power.
[0078] Alternatively, a corresponding variation curve between the correction coefficient and the detected electric quantity is preset, and after the detected electric quantity is obtained, the correction coefficient can be determined from the variation curve; and the detected electric quantity is corrected using the correction coefficient.
[0079] In this embodiment, the target battery power is used to ultimately compare with the power threshold to determine the operating mode of the vehicle.
[0080] In the present application, by correcting the detected power, the battery power can be made more accurate, avoiding the problem of inaccurate final operation mode determined due to BMS misdetection.
[0081] S103, obtaining the driving mode of the vehicle and environmental information of the environment in which the vehicle is located.
[0082] In this embodiment, the driving modes of the vehicle may include: energy-saving mode, normal mode, snow mode, sports mode, etc.
[0083] The environmental information may include at least one of road slope, atmospheric pressure, and ambient temperature, among others.
[0084] S104: Determine a target power threshold for determining an operating mode of the vehicle based on the driving mode and the environmental information.
[0085] In this embodiment, the driving mode and environmental information are input into the trained neural network to obtain the target power threshold.
[0086] Alternatively, a first power level corresponding to the driving mode is searched, a second power level corresponding to the environmental information is searched, an average of the first power level and the second power level is calculated, and the average of the first power level and the second power level is used as the target power level threshold.
[0087] S105: Determine the operation mode of the vehicle based on the relationship between the target battery power and the target power threshold, and control the vehicle to switch to the operation mode for operation.
[0088] In this embodiment, the target battery power and the target power threshold are compared; if the target battery power is greater than or equal to the target power threshold, the vehicle's operating mode is determined to be a power consumption mode; if the target battery power is less than the target power threshold, the vehicle's operating mode is determined to be a power retention mode.
[0089] In this application, the detected power of the battery detected by the battery management module is first obtained. Since the detected power is not accurate enough, the detected power needs to be corrected to obtain a more accurate target battery power for judging the operating mode of the vehicle; then the driving mode of the vehicle and the environmental information of the vehicle's environment are obtained, and the target power threshold for judging the operating mode of the vehicle is determined according to the driving mode and environmental information; finally, the vehicle operation is controlled according to the relationship between the target battery power and the target power threshold. In this application, the target power threshold for judging the operating mode of the vehicle is determined according to the driving mode and environmental information, so that the battery power threshold can be dynamically changed according to the vehicle's environment and the vehicle's driving mode, so that the set power threshold is more in line with the current vehicle condition, thereby making it possible to more accurately control the vehicle according to the power threshold that meets the current state of the vehicle.
[0090] like Figure 2 As shown, in a possible implementation manner, the implementation process of step S102 may include:
[0091] S1021, correct the detected electrical quantity to obtain a first corrected electrical quantity of the detected electrical quantity.
[0092] In this embodiment, the detected electrical quantity is corrected using a preset correction parameter to obtain a first corrected electrical quantity.
[0093] In this embodiment, the detected electrical quantity is compared with a first preset value, and the first corrected electrical quantity is determined according to the comparison result.
[0094] Specifically, Figure 3 The method for determining a first corrected electric quantity using a first preset value includes:
[0095] S11, comparing the detected power level with a first preset value to obtain a first comparison result, wherein the first preset value is determined according to the maximum power level of the battery.
[0096] In this embodiment, the first preset value can be Figure 3 The 100.1% shown in , may also be other values, which are not limited here.
[0097] S12: If the first comparison result is that the detected power is greater than or equal to the first preset value, use a first replacement value as a first correction power of the detected power.
[0098] In this embodiment, since the first preset value is the maximum value of the battery power, the battery power cannot be greater than or equal to the first preset value. If the detected power is greater than or equal to the first preset value, it means that the detected power is inaccurate and the detected power needs to be re-determined. In this application, the first replacement value is used to replace the detected power when the detected power is inaccurate.
[0099] The first alternative value is a preset value, for example, the first alternative value can be Figure 3 20% shown in .
[0100] S13: If the first comparison result is that the detected power is less than the first preset value, use the detected power as the first corrected power.
[0101] In this embodiment, if the detected power level is less than the first preset value, it means that the detected power level is relatively accurate, and the detected power level can be directly used for subsequent operations.
[0102] In the embodiment of the present application, the first preset value is used to determine the accuracy of the detected power, and the detected power is corrected in time when the detected power is inaccurate, thereby ensuring the accuracy of subsequent operations using the detected power.
[0103] S1022: Obtain the battery status of the battery.
[0104] In this embodiment, the state of the battery may include a fault state and a non-fault state. If the battery is in a fault state, it is also necessary to obtain the fault type of the battery, which may be a fault level. A larger fault level indicates a more serious battery fault.
[0105] As an example, the present application may set the fault levels to include level 1 fault, level 2 fault, level 3 fault, level 4 fault and level 5 fault. When the battery is at level 4 fault or level 5 fault, it indicates that the battery fault is very serious, for example, a battery burnout is a level 5 fault.
[0106] S1023: Correct the first corrected power according to the battery status to obtain a target corrected power of the detected power.
[0107] In this embodiment, the corresponding correction coefficient is determined according to the battery state, and the first correction power is corrected by using the correction coefficient to obtain the target correction power. For example, when the battery fails, the correction coefficient corresponding to the fault level is found according to the fault level of the battery, and the first correction power is corrected by using the correction coefficient to obtain the target correction power.
[0108] In this embodiment, if Figure 3 As shown, the method for determining the target correction power may also include:
[0109] S21, if the battery state is a fault state and the fault type is a preset type, search a preset table for a power replacement value corresponding to the first corrected power, and determine the power replacement value as a second corrected power of the detected power.
[0110] In this embodiment, the preset type may be battery burnout, battery feeding, etc. Alternatively, the preset type may be Figure 3 Specifically, when the battery is in a level 4 fault or a level 5 fault, the power substitute value corresponding to the first corrected power is searched in a preset table.
[0111] In this embodiment, the hybrid system types of the vehicle are divided into plug-in hybrid electric vehicles (PHEV) and hybrid electric vehicles (HEV). PHEV vehicles are vehicles that can be driven by electricity through charging, and HEV vehicles are vehicles that run on fuel and generate electricity.
[0112] Since vehicles are divided into PHEV and HEV, two map tables are pre-set, PHEV corresponds to map1, and HEV corresponds to map2. The map stores the correspondence between power and substitution value. After obtaining the first corrected power, the corresponding power substitution value can be found in the map table according to the first corrected power and the vehicle hybrid system type.
[0113] The present application takes into account the impact of a battery failure on the battery power. When a serious battery failure occurs, the battery power is corrected to make the battery power more accurate.
[0114] S22: If the battery state is a fault state and the fault type is not the preset type, or the battery state is a non-fault state, the first corrected electrical quantity is determined as a second corrected electrical quantity of the detected electrical quantity.
[0115] In this embodiment, when there is no battery failure or the battery failure is not serious, the battery power is relatively accurate and there is no need to correct the power. Therefore, the first corrected power does not need to be corrected.
[0116] S23: If the second corrected electrical quantity is not 0, determine the second corrected electrical quantity as the target corrected electrical quantity.
[0117] S24: If the second corrected electrical quantity is 0, obtain the current state of the vehicle controller in the vehicle.
[0118] In this embodiment, when the second correction power is 0, it is also necessary to determine whether it is caused by the initialization of the vehicle controller. Therefore, when the second correction power is 0, it is also necessary to determine the target correction power in combination with the state of the vehicle controller.
[0119] In this embodiment, the current state of the vehicle controller can be an initialized state or an uninitialized state.
[0120] S25, determining a target correction power of the detected power according to a current state of a vehicle controller in the vehicle.
[0121] Specifically, if the current state of the vehicle controller is in the initialization state, the first preset power is determined as the target correction power. If the current state of the vehicle controller is not in the initialization state, the second correction power is determined as the target correction power.
[0122] In this embodiment, if the vehicle controller is in the initialization state, the vehicle controller cannot receive the battery power sent by the BMS, resulting in the battery power being 0. Therefore, when the second corrected power is 0, it is necessary to exclude whether the power is 0 due to the initialization of the vehicle controller to ensure the accuracy of the output power. Specifically, if the current state of the vehicle controller is the initialization state, and the maintenance time of the initialization state is less than or equal to the preset time length (for example, 10 seconds), the first preset power is determined as the target corrected power.
[0123] In this embodiment, the first preset power can be set as needed. For example, the first power can be set as follows: Figure 3 101% is shown in the figure to indicate that there is a problem with the current battery charge.
[0124] S1024: Determine a target battery power for determining an operating mode of the vehicle according to the target corrected power.
[0125] In this embodiment, the target corrected power is the battery power obtained by correcting the detected power according to the battery status and the vehicle controller status. The target corrected power can reflect whether the detected battery power is accurate. For example, if the target corrected power is 101%, it means that the battery power detected at the current moment is inaccurate. Therefore, the target corrected power still cannot be used to determine the vehicle's operating mode. It is necessary to further determine the battery power that can be used to determine the vehicle's operating mode based on the target corrected power.
[0126] In this embodiment, the battery power corresponding to the target corrected power is searched, and the battery power corresponding to the target corrected power is determined as the target battery power. Alternatively, the target corrected power is multiplied by a correction coefficient to obtain the target battery power.
[0127] Alternatively, you can follow the Figure 4 The method shown in determines the target battery power, specifically:
[0128] S31, if the target corrected power is less than a second preset value, taking the difference between the target corrected power and a preset correction parameter as the target battery power, wherein the second preset value is determined based on the maximum power of the battery.
[0129] In this embodiment, the second preset value can be set as needed, for example, Figure 4 The 100% represents the maximum capacity of the battery.
[0130] If the target correction power is less than the second preset value, it means that the target correction power is credible, and the target correction power only needs to be corrected within the power range used to detect the vehicle's operating mode, which is equivalent to standardizing the target correction power.
[0131] S32: If the target corrected power is greater than or equal to the second preset value, the operating mode of the vehicle at the current moment is obtained.
[0132] In this embodiment, if the target corrected power is greater than or equal to the second preset value, it means that the target corrected power is not credible and there is a problem with the current detected power. Therefore, the target battery power can be determined according to the operation mode of the vehicle at the current moment. The operation mode of the vehicle at the current moment can be queried in the memory. The operation mode of the vehicle at the current moment is the operation mode of the vehicle determined in the previous judgment cycle. Since a new operation mode has not yet been determined, the vehicle is still operating according to the previously determined operation mode at the current moment.
[0133] S33: If the current running mode of the vehicle is the power consumption mode, use the second preset power as the target battery power.
[0134] In this embodiment, if the current operating mode is the power consumption mode, it means that the vehicle has sufficient power. The second preset power can be set as the target power. The second preset power can be set to a relatively large value to indicate that the current power is sufficient. For example, the second preset power can be set as follows: Figure 4 Of course, the second preset power level can also be set to 99% or 95%, etc.
[0135] S34: If the current running mode of the vehicle is the power maintaining mode, a third preset power is used as the target battery power, wherein the third preset power is less than the second preset power.
[0136] In this embodiment, if the current operating mode is the power maintenance mode, it means that the power is insufficient. The target battery power can be set to a third preset power. The third preset power can be set to a relatively small value to indicate that the current power is insufficient. For example, the third preset power can be set to Figure 4 Of course, the third preset power level can also be set to 5% or 2%, etc.
[0137] In an embodiment of the present application, the detected power is corrected multiple times to obtain a target corrected power so that the detected power can more accurately represent the state of the battery at the current moment. Then, the target battery power used to judge the operating mode is further determined based on the target corrected power, so that the determined target battery power is closer to the current state of the battery, thereby making the operating mode determined using the target battery power more accurate.
[0138] like Figure 5 As shown, in a possible implementation manner, the implementation process of step S104 may include:
[0139] S1041, searching for an initial power threshold corresponding to the driving mode for determining an operating mode of the vehicle, wherein the initial power threshold includes an initial upper threshold and an initial lower threshold.
[0140] In this embodiment, a correspondence table between driving modes and initial power thresholds is pre-set. Specifically, a correspondence table between driving modes and initial upper thresholds, and a correspondence table between driving modes and initial lower thresholds are pre-set; the initial power threshold required at the current moment can be determined by looking up the table, for example, Figure 6 Map1 in is the correspondence table between driving mode and initial upper limit threshold. Figure 6 Map2 in is a correspondence table between driving modes and initial lower limit thresholds.
[0141] S1042, searching for a power correction coefficient corresponding to the environmental information.
[0142] In this embodiment, power correction coefficients corresponding to different environmental parameters are preset. The environmental parameter may be at least one of road slope, atmospheric pressure, and ambient temperature. In this application, the environmental parameter may be road slope, atmospheric pressure, and ambient temperature. Different road slopes correspond to different power correction parameters. Different atmospheric pressures correspond to different power correction parameters, and different ambient temperatures correspond to different power correction parameters.
[0143] S1043, using the power correction coefficient to correct the initial power threshold to obtain a target power threshold for determining the operating mode of the vehicle, wherein the target power threshold includes an upper power threshold and a lower power threshold.
[0144] In this embodiment, the target power threshold is obtained by multiplying the initial power threshold by the power correction coefficient.
[0145] For example, if the initial upper limit threshold is A, the power correction coefficient corresponding to the road slope is a, the power correction coefficient corresponding to the atmospheric pressure is b, and the power correction coefficient corresponding to the ambient temperature is c; calculate A×a×b×c to get the power upper limit threshold.
[0146] In an embodiment of the present application, multiple factors are considered for the battery threshold, and a target battery threshold is determined based on the ambient temperature and the driving mode of the vehicle. The target battery threshold can change with the state of the vehicle and the environment in which the vehicle is located, so that the target battery threshold is more in line with the current operating conditions.
[0147] like Figure 6 As shown, in a possible implementation manner, the implementation process of step S105 may include:
[0148] S1051: If the target battery power is greater than the power upper limit threshold, control the vehicle to enter the power consumption mode.
[0149] In this embodiment, if the target battery power is greater than the upper power limit threshold, it means that the battery power is sufficient and the vehicle can enter the power consumption mode for operation.
[0150] After the vehicle enters the power consumption mode, the vehicle's power will be consumed. As the power decreases, when the battery power is less than the upper power threshold, the vehicle continues to operate in the power consumption mode; when the battery power is less than the lower power threshold, the vehicle exits the power consumption mode and begins to switch to the power retention mode.
[0151] S1052: If the target battery power is less than the power lower limit threshold and the current operation mode of the vehicle is a power retention mode, control the vehicle to maintain the power retention mode.
[0152] In this embodiment, if the target battery power is less than the lower power threshold, it means that the battery power is relatively low, and the vehicle operates in the power maintenance mode.
[0153] The current operating mode of the vehicle is the operating mode of the vehicle at the current moment.
[0154] S1053: If the target battery power is less than the power lower limit threshold and the current operation mode of the vehicle is a power consumption mode, control the vehicle to start switching from the power consumption mode to the power retention mode.
[0155] In this embodiment, the power consumption mode is converted to the power retention mode to the CS-charge mode. The CS-charge mode is the process state of CD converting to CS. After CD enters CS-charge, the engine is started to supplement power. When the SOC threshold meets specific conditions, it jumps to the CS mode.
[0156] S1054, during the transition of the vehicle from the power consumption mode to the power retention mode, if the target battery power is greater than or equal to a first calculated value, the vehicle is controlled to enter the power retention mode, wherein the first calculated value is the product of a threshold difference and a preset threshold correction coefficient, and the threshold difference is the difference between the upper power threshold and the lower power threshold.
[0157] In this embodiment, the threshold correction coefficient can be set as needed, for example, the threshold correction coefficient can be set to 0.6 or 0.5.
[0158] S1055: If the target battery power is greater than the lower power threshold and the target battery power is less than the upper power threshold, control the vehicle to continue to maintain the current operating mode.
[0159] In this embodiment, if the target battery power is greater than the lower power threshold and the target battery power is less than the upper power threshold, the operation mode of the vehicle remains unchanged.
[0160] As an example, when the vehicle is in power consumption mode, if it is detected that the target battery power is greater than the lower power limit threshold and the target battery power is less than the upper power limit threshold, the vehicle continues to include the power consumption mode until the target battery power is less than the lower power limit threshold, and the vehicle enters the CS-charge mode.
[0161] When the vehicle is in the charge retention mode, if it is detected that the target battery charge is greater than the lower charge threshold and the target battery charge is less than the upper charge threshold, the vehicle continues to include the charge retention mode until the target battery charge is greater than the upper charge threshold, and the vehicle enters the charge consumption mode.
[0162] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
