[0037] Optional, such as Figure 3The schematic diagram of the overall vehicle torque distribution process shown in the figure receives data information such as the power battery state of charge (State of Charge, referred to as SOC), the driver's required torque TReq, the engine operating state, the engine speed ωEng, and the actual engine torque TEngAct through the acquisition module; the engine operating state is identified through the engine operating state judgment module, and the engine target torque calculation module determines the calculation method of the above-mentioned engine target torque initial value according to the operating state; the engine target torque allowable range calculation module is used to determine the allowable range of the engine initial torque, and then the engine economy target torque initial calculation module is used to calculate the engine target torque initial value TEngTargRaw considering the vehicle economy within the above-mentioned allowable range, and the engine dynamic efficiency calculation module tests and calculates the average dynamic efficiency ηEngDyn of the working point where the torque curve fluctuates severely and its surrounding working points, and then the engine target torque comprehensive arbitration module is used to realize the correction processing of the engine initial torque, and the final value of the engine target torque is obtained and output to the engine execution module, and the actual engine torque value is obtained at the same time, and fed back to the motor target torque calculation module; finally, the motor target torque TMotAct is calculated and sent to the motor execution module for response to complete the torque distribution.

[0038] Through the embodiments of the present invention, the economic target torque of the engine and the motor is first calculated based on the steady-state efficiency of the assembly, and then the working point that causes the large fluctuation of the engine target torque is found for dynamic testing to obtain the dynamic average efficiency of the working point, which is used to correct the economic target torque of the engine and the motor. At the same time, the acceptable drivability range and the ideal drivability curve of the engine and motor torque distribution are determined according to the torque distribution limit of pressing the accelerator pedal and releasing the accelerator pedal. With the acceptable drivability range as the highest priority, the economic target torque is corrected by comprehensively considering the dynamic average efficiency of the engine and the ideal drivability torque distribution curve to obtain the final engine and motor target torque that combines drivability and economy, achieve better economy and drivability, and achieve the purpose of torque distribution based on the dynamic efficiency of each assembly of the vehicle, thereby achieving the technical effect of correcting the torque distribution that takes into account the economy and drivability of the target vehicle, thereby solving the technical problem that the existing torque distribution method does not consider economy and drivability at the same time, resulting in unsatisfactory actual driving effect of the vehicle.

[0039] In an optional embodiment, before determining the initial value of the engine target torque of the target vehicle based on the status data, the method further includes: judging whether the engine assembly is in an operating state based on the operating state information of the engine assembly in the status data; if the engine assembly is not in an operating state, determining the final value of the engine target torque and the actual engine torque value to be 0, and using the driver required torque value of the target vehicle as the motor target torque value; if the engine assembly is in an operating state, determining the initial value of the engine target torque of the target vehicle based on the status data.

[0040] In an embodiment of the present application, before determining the initial value of the engine target torque of the target vehicle based on the above-mentioned status data, it is first determined whether the above-mentioned engine is in a running state. If it is determined that the engine is in a stopped and non-running state, the engine target torque TEngTarg and the actual torque TEngAct are 0, and the motor target torque is equal to the driver's required torque TReq, which is sent to the motor execution module for execution.

[0041] Optionally, if it is identified that the engine is in the running state, the engine target torque allowable range calculation module in the engine target torque calculation module will determine the allowable variation range and ideal variation curve of the engine target torque with the driver's demand torque based on the driving requirements of the two working conditions of stepping on and releasing the accelerator pedal, that is, the acceleration state or the deceleration state.

[0042] In an optional embodiment, the above-mentioned determination of the initial value of the engine target torque of the target vehicle based on the above-mentioned state data includes: obtaining a first torque curve in a first operating state of the above-mentioned target vehicle, wherein the first operating state is the operating state of the above-mentioned target vehicle when the driver steps on the accelerator (Tipin); obtaining a second torque curve in a second operating state of the above-mentioned target vehicle, wherein the second operating state is the operating state of the above-mentioned target vehicle when the driver releases the accelerator (Tipout); determining an initial engine torque range based on the above-mentioned first torque curve and the above-mentioned second torque curve; and calculating the initial value of the engine target torque based on the above-mentioned engine initial torque range.

[0043] In the embodiments of the present application, Figure 4The schematic diagram of the torque curve change structure is shown, where L2 is the ideal engine target torque change curve with the driver's demand torque from the perspective of drivability, that is, the engine target torque is equal to the driver's demand torque. When the driver steps on the accelerator pedal, the engine target torque follows the loading to ensure that the acceleration feeling of the entire acceleration process is smooth and consistent. When the driver releases the accelerator pedal, the engine target torque follows the unloading to ensure that the deceleration feeling and engine sound of the entire process are consistent with the driver's expectations. L1 is the maximum engine target torque curve allowed under the condition of releasing the accelerator pedal, and L3 is the minimum engine target torque curve allowed under the condition of stepping on the accelerator pedal. The area surrounded by L1 and L3 is the allowable range of the engine initial torque for drivability. In addition, the relationship between the initial value of the engine target torque TEngTargRaw and the driver's demand torque TReq corresponds to the L4 curve.

[0044] It should be noted that the engine economy target torque initial calculation module calculates the engine target torque initial value TEngTargRaw taking vehicle economy into consideration within the above-mentioned allowable range.

[0045] In an optional embodiment, the above-mentioned engine target torque initial value is calculated based on the above-mentioned engine target torque range, including: within the above-mentioned engine target torque range, the engine target torque initial value is calculated according to the engine speed in the above-mentioned state data and the above-mentioned driver demand torque, and an engine target torque initial value calculation process is completed once; the above-mentioned engine speed and the above-mentioned driver demand torque are changed, and the above-mentioned engine target torque initial value calculation process is repeated to obtain the above-mentioned engine target torque initial curve.

[0046] In the embodiment of the present application, the steady-state efficiency ηEngStat of the engine in the vehicle driving data is calculated and processed to obtain the following: Figure 5 The schematic diagram of the initial target operating point of the engine is shown; and within the above-mentioned engine target torque range, the battery state data SOC in the above-mentioned battery assembly and the engine speed in the above-mentioned engine assembly are calculated and processed ωEng to obtain the first initial torque value TEngTargRaw of the engine.

[0047] Optionally, based on the common operating condition information preset in the vehicle driving data, the initial target operating point that causes severe fluctuations in the engine target torque curve is screened out, and the engine dynamic efficiency calculation module is used to test and calculate the average dynamic efficiency ηEngDyn data of the operating point and its surrounding operating points, replacing the shown steady-state efficiency ηEngStat data; the above-mentioned average dynamic efficiency data and the above-mentioned first initial torque value of the engine are calculated to obtain the second initial torque value of the engine, and the engine target torque initial value calculation process is completed once; after repeating the above-mentioned engine target torque initial value calculation process multiple times, the above-mentioned engine target torque initial value is obtained.

[0048] In an optional embodiment, the above-mentioned engine initial torque value and the engine target torque initial value are corrected based on the above-mentioned driving data to obtain the engine target torque value and the engine target torque final value, including: judging whether the torque curve of the above-mentioned engine initial torque exceeds the above-mentioned engine initial torque range; if the calculated initial target torque jumps relative to the engine operating point before and after the moment, causing the engine target torque to change significantly, then within the above-mentioned engine initial torque range, a suboptimal solution for economy is calculated based on the dynamic steady-state efficiency of the above-mentioned engine, motor, battery, and transmission assembly, the average dynamic efficiency of the engine in this dynamic process is determined through actual testing, and the above-mentioned engine initial torque value and the engine target torque initial value are corrected to obtain the engine target torque value and the engine target torque final value.

[0049] Optionally, the above-mentioned engine target torque initial value is corrected based on the above-mentioned driving data to obtain the engine target torque final value, including: judging whether the change amplitude of the above-mentioned engine target torque initial curve exceeds the engine torque curve change amplitude threshold value preset in the above-mentioned driving data; if the change amplitude of the above-mentioned engine target torque initial curve exceeds the above-mentioned preset engine torque curve change amplitude threshold value, then correcting the above-mentioned engine target torque initial value based on the preset dynamic efficiency of the above-mentioned engine assembly to obtain the engine target torque final value.

[0050] Optionally, before the initial value of the engine target torque is corrected based on the preset dynamic efficiency of the engine assembly, the method further includes: calculating the initial target operating point of the engine assembly based on the steady-state efficiencies of the multiple assemblies; determining a fluctuating operating point from the initial target operating point according to preset operating condition data in the driving data, wherein the fluctuating operating point is the initial target operating point that causes fluctuations in the initial curve of the engine target torque; and calculating the fluctuating operating point to obtain the preset dynamic efficiency.

[0051] In the embodiment of the present application, the engine target torque comprehensive arbitration module is used to realize the comprehensive consideration of the engine target torque on the vehicle drivability and economy, such as Figure 4 As shown, the corrected engine target torque curve is like the L5 curve. The engine target torque is corrected at ①②③④. The initial engine target torque at ② and ④ exceeds the drivability restriction area. The initial engine target torque at ① and ③ changes too much when the accelerator pedal is released. Therefore, the engine dynamic efficiency is recalculated within the allowable range of drivability to find the suboptimal solution of economy as the corrected engine target torque TEngTarg.

[0052] In an optional embodiment, the above-mentioned calculation of the final value of the engine target torque and the driver demand torque value to obtain the motor target torque value, and completing the torque distribution based on the motor target torque value, includes: obtaining the actual torque value of the engine when the engine assembly is running based on the final value of the engine target torque; calculating the difference between the actual engine torque value and the driver demand torque value to obtain the motor target torque value; and using the motor assembly to run based on the motor target torque value to complete the torque distribution.

[0053] In an embodiment of the present application, the final value of the engine target torque is obtained and output to the engine execution module, and the actual engine torque TEngAct is fed back to the motor target torque calculation module. The motor target torque TMotAct is calculated by the difference between the driver's required torque TReq and the actual engine torque TEngAct, and sent to the motor execution module for response to complete the torque distribution.

[0054] Through the above steps, it is possible to achieve not only the use of engine steady-state efficiency for calculations, but also to use engine dynamic efficiency to correct the engine target torque according to test conditions, thereby optimizing the economy of the vehicle during actual driving. At the same time, considering the drivability requirements, by calculating the limitation range of drivability on the engine target torque, the possibility of drivability problems caused by torque distribution control is reduced.
