[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0046] In a first aspect, an embodiment of the present application provides a method for determining an operating mode based on a virtual dual battery.

[0047] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for determining the operation mode based on virtual dual batteries of the present application. Figure 1 As shown, the method for determining the operation mode based on the virtual dual battery includes:

[0048] Step S10: Detecting that the vehicle is powered on, and determining the initial power of the virtual dual battery according to the initial power of the SOC, wherein the virtual dual battery includes: an energy recovery battery and a driving power generation battery;

[0049] Exemplarily, a power-on signal of the vehicle is detected. If a power-on signal is detected, it is determined that the vehicle is powered on. The SOC initial power is obtained, and the initial power of the virtual dual battery is determined by the SOC initial power, wherein the vehicle power battery is divided into two virtual batteries, namely, an energy recovery battery and a driving power generation battery. For example, if the SOC initial power is obtained, the SOC initial power is divided equally to determine the initial power of the energy recovery battery and the initial power of the driving power generation battery.

[0050] Step S20: determining the battery status of the vehicle according to the vehicle operation mode;

[0051] Exemplarily, the battery state of the vehicle is determined according to the operation mode of the vehicle, and the battery state of the vehicle includes the energy recovery battery state and the driving recovery battery state. For example, if the operation mode of the vehicle is the driving power generation mode or the parking power generation mode, the battery state is determined to be the driving power generation battery state. Otherwise, the battery state is determined to be the energy recovery battery state.

[0052] Step S30: obtaining the SOC power based on the battery state, the initial power of the energy recovery battery and the initial power of the driving power generation battery;

[0053] Exemplarily, the battery state is determined, and the power information under the current battery state is obtained. For example, if the current battery state is an energy recovery battery state, the discharge or charge information under the energy recovery battery state is obtained, and the obtained discharge or charge information under the energy recovery battery state, the initial power of the energy recovery battery, and the initial power of the driving power generation battery are added to obtain the SOC power; or, if the current battery state is a driving power generation battery state, the discharge or charge information under the driving power generation battery is obtained, and the obtained discharge or charge information under the driving power generation battery state, the initial power of the driving power generation battery, and the initial power of the energy recovery battery are added to obtain the SOC power.

[0054] Step S40: Determine the vehicle operation mode according to the SOC power and the required power of the vehicle.

[0055] Exemplarily, after obtaining the SOC power, the vehicle power requirement is obtained, and when the SOC power and the vehicle power requirement meet the preset conditions, the vehicle operation mode is determined. For example, when the SOC power and the vehicle power requirement meet the preset interval, the vehicle operation mode is determined, and the vehicle operation modes include: driving power generation mode, pure electric mode, pure engine mode, and hybrid drive mode.

[0056] In this embodiment, the initial power of the virtual dual battery is determined according to the SOC initial power, wherein the virtual dual battery includes: an energy recovery battery and a driving power generation battery; according to the vehicle operation mode, the battery state of the vehicle is determined; based on the battery state, the initial power of the energy recovery battery and the initial power of the driving power generation battery, the SOC power is obtained; according to the SOC power and the required power of the whole vehicle, the vehicle operation mode is determined, which solves the problem of converting the output torque of the engine into the whole vehicle power in the related technology, and reflects the output capacity of the whole vehicle.

[0057] Furthermore, in one embodiment, determining the vehicle operation mode according to the SOC power and the vehicle required power includes:

[0058] Step S41: when the SOC vehicle power requirement is in the second preset power range and the SOC power range is in the first preset power range, determining the vehicle operation mode according to the energy recovery battery power;

[0059] Step S42: If the power level of the energy recovery battery is greater than a first preset threshold, the vehicle operation mode is a pure electric mode;

[0060] Step S43: If the power level of the energy recovery battery is less than or equal to the first preset threshold, the vehicle operation mode is the pure engine mode.

[0061] Exemplarily, the SOC vehicle power demand is obtained, and the obtained SOC vehicle power demand is compared with the second preset power interval. If the SOC vehicle power demand is obtained to be in the second preset power interval, the SOC power is compared with the first preset power interval. If the SOC power is obtained to be in the first preset power interval, the energy recovery battery power is obtained, and the vehicle operation mode is determined by the energy recovery battery power. For example, the SOC vehicle power demand is between P1-P2, and the SOC power is between C1-C2, where P1 is the load transfer profit and loss point, and P2 is the energy recovery power point.

[0062] The energy recovery battery power is compared with the first preset threshold to determine the vehicle operation mode; if the energy recovery battery power is greater than the first preset threshold, the vehicle operation mode is determined to be pure electric mode (M); if the energy recovery battery power is less than or equal to the first preset threshold, the vehicle operation mode is determined to be pure engine mode (E). For example, if the energy recovery battery power is greater than r, the vehicle operation mode is determined to be pure electric mode (M); if the energy recovery battery power is less than or equal to r, the vehicle operation mode is determined to be pure engine mode (E), where r is a calibration value that can avoid repeated switching between driving power generation mode and pure electric mode.

[0063] In this embodiment, by considering the power of the energy recovery battery, the vehicle operation mode is determined to be pure electric mode or pure engine mode, which solves the problem in the related art that the vehicle operation mode can be determined without calculating the power relationship between the driving power generation battery and the energy recovery battery.

[0064] Furthermore, in one embodiment, determining the vehicle operation mode according to the SOC power and the vehicle required power includes:

[0065] Step S44: when the SOC vehicle demand power is in the first preset power range, and the SOC power range is in the first preset power range, the vehicle operation mode is the pure electric mode;

[0066] Step S45: when the SOC vehicle power requirement is in the third preset power range, and the SOC power range is in the second preset power range, the vehicle operation mode is the pure engine mode;

[0067] Step S46: when the SOC vehicle power requirement is in the fourth preset power range, and the SOC power range is in the third preset power range, the vehicle operation mode is the pure electric mode;

[0068] Step S47: When the SOC vehicle demand power is in the fifth preset power range and the SOC power range is in the third preset power range, the vehicle operation mode is the hybrid drive mode.

[0069] Exemplarily, when the SOC vehicle power demand is between 0-P1 and the SOC charge is between 0-C1, the vehicle operation mode is determined to be pure electric mode (M); if the SOC vehicle power demand is between P2-P4 and the SOC charge is between C1-C2, the vehicle operation mode is determined to be pure engine mode (E); if the SOC vehicle power demand is between P2-P3 and the SOC charge is between C2-C3, the vehicle operation mode is determined to be pure electric mode (M); if the SOC vehicle power demand is between P3-P4 and the SOC charge is between C2-C3, the vehicle operation mode is determined to be hybrid drive mode (M+E), where P3 is the optimal power generation power point.

[0070] In this embodiment, the vehicle operation mode is determined by comparing the vehicle demand power and SOC power in different intervals, thereby solving the problem of improving the accuracy of the vehicle operation mode in the related art.

[0071] Furthermore, in one embodiment, before determining the vehicle operation mode according to the SOC power and the vehicle required power, the method further includes:

[0072] Step S48: When the SOC power is less than the second preset threshold, the vehicle operation mode is determined to be the driving power generation mode.

[0073] Exemplarily, when the SOC power is less than C1, the vehicle operation mode is determined to be the driving power generation mode.

[0074] In this embodiment, by comparing the SOC power and the second preset threshold, it is determined that the vehicle operation mode is the driving power generation mode, which solves the problem of frequent switching of the vehicle operation mode between driving power generation and pure electric in the related art.

[0075] Furthermore, in one embodiment, the battery state of the vehicle includes a driving power generation battery state, and determining the battery state of the vehicle according to the vehicle operation mode includes:

[0076] Step S21: determining whether the battery state of the vehicle is a driving power generation battery state according to the vehicle operation mode;

[0077] Step S22: if the detected vehicle operation mode is driving power generation or parking power generation, determining that the battery state of the vehicle is a driving power generation battery state;

[0078] Step S23: or, if it is detected that the energy recovery battery is fully charged, and the vehicle operation mode is any one of motor braking + engine reverse drag + auxiliary braking, motor braking + engine reverse drag, and single motor braking, then the battery state of the vehicle is determined to be a driving power generation battery state;

[0079] Step S24: Or, if it is detected that the energy recovery battery is empty and the vehicle operation mode is not any one of motor braking + engine reverse drag + auxiliary braking, motor braking + engine reverse drag, and single motor braking, then it is determined that the battery state of the vehicle is a driving power generation battery state.

[0080] Exemplarily, according to the current vehicle operation mode, it is determined whether the battery state of the vehicle is a driving power generation battery state. If it is detected that the vehicle operation mode is a driving power generation mode or a parking power generation mode, the battery state of the vehicle is determined to be a driving power generation battery state. Alternatively, it is determined that the energy recovery battery is full, and the vehicle operation mode is any one of motor braking + engine reverse drag + auxiliary braking, motor braking + engine reverse drag, and single motor braking, and the battery state of the vehicle is determined to be a driving power generation battery state. Alternatively, it is determined that the energy recovery battery is empty, and the vehicle operation mode is not any one of motor braking + engine reverse drag + auxiliary braking, motor braking + engine reverse drag, and single motor braking, and the battery state of the vehicle is determined to be a driving power generation battery state.

[0081] In this embodiment, the vehicle operation mode is used to determine whether the battery state is a driving power generation battery state, so that the driving power generation battery is used according to the different vehicle operation modes, and the problem of using the driving power generation for motor drive, which causes a significant reduction in the efficiency of the entire vehicle due to the loss of motor and battery charging and discharging efficiency, is avoided.

[0082] Further, in one embodiment, the battery state of the vehicle includes a driving power generation battery state and an energy recovery battery state, and the SOC power is obtained based on the battery state, the initial power of the energy recovery battery and the initial power of the driving power generation battery, including:

[0083] Step S31: if it is determined that the battery state of the vehicle is a driving power generation battery state, and it is detected that the power of the driving power generation battery is not full, then the driving power generation battery is integrated;

[0084] Step S32: if it is determined that the battery state of the vehicle is an energy recovery battery state, integrating the energy recovery battery;

[0085] Step S33: respectively obtaining the integrated power of the driving power generation battery, the integrated power of the energy recovery battery, the initial power of the energy recovery battery and the initial power of the driving power generation battery to obtain the SOC power.

[0086] Exemplarily, when it is determined that the battery state of the vehicle is a driving power generation battery state, it is detected whether the power of the driving power generation battery is saturated. If the power of the driving power generation battery is not saturated, the driving power generation battery is integrated, wherein integrating the driving power generation battery includes charging or discharging the driving power generation battery. For example, when the vehicle operation mode is a driving power generation mode or a parking power generation mode, the driving power generation battery is charged. Alternatively, when the energy recovery battery is full and the vehicle operation mode is a braking mode, the driving power generation battery is charged. Alternatively, when the energy recovery battery is empty and the vehicle operation mode is not a braking mode, the driving power generation battery is discharged.

[0087] When it is determined that the battery state of the vehicle is an energy recovery battery state, the energy recovery battery is integrated, wherein integrating the energy recovery battery includes charging or discharging the energy recovery battery. For example, if it is detected that the energy recovery battery is not full and the vehicle operation mode is a braking mode, the energy recovery battery is charged. Or, when the vehicle operation mode is a hybrid mode or an engine mode, the energy recovery battery is discharged.

[0088] If the amount of electricity charged by the driving power generation battery, the amount of electricity charged by the energy recovery battery, and the initial amount of electricity of the energy recovery battery and the initial amount of electricity of the driving power generation battery are added together, the SOC amount is obtained. Alternatively, the amount of electricity discharged by the driving power generation battery, the amount of electricity discharged by the energy recovery battery, and the initial amount of electricity of the energy recovery battery and the initial amount of electricity of the driving power generation battery are added together to obtain the SOC amount. Alternatively, the amount of electricity charged by the driving power generation battery, the amount of electricity discharged by the energy recovery battery, and the initial amount of electricity of the energy recovery battery and the initial amount of electricity of the driving power generation battery are added together to obtain the SOC amount. Alternatively, the amount of electricity discharged by the driving power generation battery, the amount of electricity charged by the energy recovery battery, and the initial amount of electricity of the energy recovery battery and the initial amount of electricity of the driving power generation battery are added together to obtain the SOC amount.

[0089] In this embodiment, the driving power generation battery or the energy recovery battery is charged or discharged according to the battery status, and the SOC power is obtained according to the initial power of the energy recovery battery and the initial power of the driving power generation battery. Therefore, there is no need to calculate the power-deficit relationship between the driving power generation battery and the energy recovery battery, and the current SOC power can be accurately obtained.

[0090] Further, in one embodiment, determining the initial power of the virtual dual battery according to the initial power of the SOC includes:

[0091] Step S11: if the SOC initial power is greater than a second preset threshold, determining that the initial power of the energy recovery battery is the SOC initial power minus the second preset threshold, and the initial power of the driving power generation battery is the second preset threshold;

[0092] Step S12: If the SOC initial power is less than or equal to a second preset threshold, it is determined that the initial power of the energy recovery battery is 0, and the initial power of the driving power generation battery is the SOC initial power.

[0093] Exemplarily, if the SOC initial charge is greater than C1, the initial charge value of the energy recovery battery is determined to be the SOC initial charge minus C1, and the initial charge value of the driving power generation battery is C1. If the SOC initial charge is less than or equal to C1, the initial charge value of the energy recovery battery is determined to be 0, and the initial charge value of the driving power generation battery is the SOC initial charge.

[0094] In this embodiment, the initial power of the energy recovery battery and the initial power of the driving power generation battery are divided by comparing threshold values, and the division is suitable for practical applications.
