Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

[0022] In view of the above technical problems, the present invention comprehensively considers the universal characteristics of the engine, four-wheel drive torque distribution, engine dynamic start-stop, the working modes of vehicle series or parallel, and power battery (SOC) management through the vehicle control unit (VCU). At the same time, it coordinates the cooperation of various controllers such as the engine management system (EMS), motor controller unit (MCU), transmission control unit (TCU), range extender generator controller (GCU), and battery management system (BMS), and precisely adjusts the engine operating point. By managing the start-stop of the engine and the power battery (SOC), the fuel consumption of the hybrid vehicle is reduced, and the optimal fuel economy of the whole vehicle is achieved.

[0023] According to a first aspect of the present invention, the present invention provides a fuel consumption optimization method based on the vehicle power balance condition. Figure 1 FIG. shows a schematic flowchart of a fuel consumption optimization method 100 based on the vehicle power balance condition according to an embodiment of the present invention. The method 100 includes the following steps:

[0024] Step S110, obtain the vehicle speed in real time to determine the level to which the vehicle speed belongs.

[0025] Specifically, the levels to which the vehicle speed belongs can be divided into: low-speed level, medium-speed level, high-speed level, ultra-high-speed level, etc.

[0026] Step S120, control the start-stop of the engine based on the level to which the vehicle speed belongs.

[0027] Specifically, when the vehicle speed is at a low speed level, the vehicle is controlled to run purely on electricity and the engine is turned off; when the vehicle speed is at a medium speed level, a high speed level or an ultra-high speed level, the engine start and stop are controlled according to the current WLTC working condition of the vehicle. Among them, the engine start and stop are jointly controlled by the vehicle control unit (VCU) coordinating the engine management system (EMS) and the range extender generator controller (GCU). Preferably, the engine has a relatively wide economic range.

[0028] Step S130, after triggering the engine to enter the starting state, adjust the working mode of the vehicle based on the currently obtained vehicle speed in real time, where the working mode of the vehicle includes a series mode and a parallel mode.

[0029] Specifically, when the vehicle speed of the vehicle is lower than a certain threshold, the working mode of the vehicle can be adjusted to the series mode; when the vehicle speed of the vehicle gradually increases and is greater than or equal to a certain threshold, the working mode of the vehicle is adjusted to the parallel mode. Among them, in the series mode, the vehicle is driven in series by an internal combustion engine and an electric motor; in the parallel mode, the vehicle is driven in parallel by an internal combustion engine and an electric motor.

[0030] The method proposed in this application determines the level to which the vehicle speed belongs by obtaining the vehicle speed of the vehicle in real time; controls the engine start and stop based on the level to which the vehicle speed belongs; after triggering the engine to enter the starting state, adjusts the working mode of the vehicle based on the currently obtained vehicle speed in real time, where the working mode of the vehicle includes a series mode and a parallel mode, realizes the control of the engine start and stop according to the current vehicle speed condition of the vehicle, achieves precise control of the dynamic start and stop of the engine, and then reasonably adjusts and switches the working mode of the vehicle according to the real-time vehicle speed when the engine is in the starting state, reduces the fuel consumption of the hybrid vehicle, and realizes the optimal fuel economy of the vehicle.

[0031] In one embodiment, step S110 may include:

[0032] Step S111, compare the vehicle speed of the vehicle with a first vehicle speed threshold to obtain a first comparison result.

[0033] Specifically, the first vehicle speed threshold may be 60 kilometers per hour. For example: compare the vehicle speed of the vehicle with 60 kilometers per hour to obtain a first comparison result. It can be understood that the first vehicle speed threshold may be set by the vehicle manufacturer before the vehicle leaves the factory or set manually by the user, and no specific limitation is made here.

[0034] Step S112, for the case where the first comparison result indicates that the vehicle speed of the vehicle is less than the first vehicle speed threshold, determine that the vehicle speed belongs to the low speed level.

[0035] Exemplarily, when the vehicle speed of the vehicle is less than 60 kilometers per hour, it is determined that the vehicle speed of the vehicle is at the low speed level.

[0036] In step S113, for the case where the first comparison result indicates that the vehicle speed is greater than or equal to the first vehicle speed threshold, it is determined that the vehicle speed belongs to a non-low speed level.

[0037] Exemplarily, when the vehicle speed is greater than or equal to 60 kilometers per hour, it is determined that the vehicle speed of the whole vehicle is at a non-low speed level.

[0038] In one embodiment, step S120 may include:

[0039] In step S121, for the case where the vehicle speed belongs to the low speed level, control the engine to stop working.

[0040] Exemplarily, when the vehicle speed is less than 60 kilometers per hour, control the engine to stop working. At this time, the whole vehicle is in a pure electric driving state.

[0041] In step S122, for the case where the vehicle speed belongs to the non-low speed level, control the engine to start.

[0042] Exemplarily, when the vehicle speed is greater than or equal to 60 kilometers per hour, control the engine to start.

[0043] It can be understood that step S112 and step S113, step S121 and step S122 respectively represent different steps executed based on different comparison results, and there is no sequential execution order.

[0044] In the above method, by comparing the vehicle speed with the first vehicle speed threshold to obtain the first comparison result; for the case where the first comparison result indicates that the vehicle speed is less than the first vehicle speed threshold, it is determined that the vehicle speed belongs to the low speed level; for the case where the first comparison result indicates that the vehicle speed is greater than or equal to the first vehicle speed threshold, it is determined that the vehicle speed belongs to the non-low speed level; based on the level to which the vehicle speed belongs, control the start and stop of the engine, including: for the case where the vehicle speed belongs to the low speed level, control the engine to stop working; for the case where the vehicle speed belongs to the non-low speed level, control the engine to start, which realizes precise control of the start and stop of the engine and the engine operating point according to the current speed in the actual driving process of the whole vehicle, combines with the first vehicle speed threshold, enables the engine to always work in the optimal range, reduces the fuel consumption of the whole vehicle, and improves the economy of the whole vehicle.

[0045] Optionally, the method further includes: triggering the engine to enter the starting state based on the state of charge of the vehicle battery and the pedal demand power.

[0046] Specifically, when the current vehicle speed exceeds a certain threshold, the engine can be dynamically triggered to enter the starting state according to the state of charge of the vehicle's battery and the pedal demand power. For example, when the current vehicle speed is greater than 30 kilometers per hour, the engine can be triggered to enter the starting state according to the state of charge of the vehicle's battery and the dynamic change of the pressure applied by the user manually to the pedal. The above method triggers the engine to enter the starting state based on the state of charge of the vehicle's battery and the pedal demand power, realizes the precise control of the operating point of the engine according to the overall vehicle power condition and demand power, improves the power performance and drivability of the overall vehicle, and reduces the fuel consumption of the overall vehicle.

[0047] Optionally, triggering the engine to enter the starting state based on the state of charge of the vehicle's battery and the pedal demand power includes: when the vehicle is in a dynamic working condition and the actual power of the vehicle is lower than the battery balanced state of charge, dynamically triggering the engine to enter the starting state according to the pedal demand power.

[0048] Specifically, when the actual power of the vehicle is lower than the power balance state, that is, when the battery pack power is lower than the standard power in the power balance state, the engine can be dynamically triggered to enter the starting state according to the pedal demand power at the same time. Among them, the pedal demand power is input by the user manually applying pressure to the throttle, and the pedal demand power is in a proportional relationship with the pressure applied by the user manually to the throttle. For example, when the pressure applied by the user manually to the throttle is greater than or equal to a certain threshold, the engine enters the starting state; when the vehicle speed decreases or the user loosens the throttle or the actual power of the vehicle is greater than or equal to the battery balanced state of charge, the engine is triggered to stop. The above method realizes the scientific control of the overall vehicle power supply and engine power supply by the vehicle control unit (VCU) and the engine management system (EMS) at the same time by dynamically triggering the engine to enter the starting state when the vehicle is in a dynamic working condition and the actual power of the vehicle is lower than the battery balanced state of charge, and improves the power supply efficiency and fuel economy of the overall vehicle.

[0049] In one embodiment, step S130 may include:

[0050] Step S131, comparing the currently obtained current vehicle speed with a second vehicle speed threshold to obtain a second comparison result.

[0051] Specifically, the second vehicle speed threshold may be set by the vehicle manufacturer before the vehicle leaves the factory or set manually by the user, and no specific limitation is made here. For example, when the second vehicle speed threshold is 70 kilometers per hour, the currently obtained current vehicle speed is compared with 70 kilometers per hour to obtain a second comparison result.

[0052] Step S132, for the case where the second comparison result indicates that the currently obtained vehicle speed is less than or equal to the second vehicle speed threshold, control the whole vehicle to enter the series mode.

[0053] Exemplarily, when the currently obtained vehicle speed is less than or equal to 70 kilometers per hour, control the whole vehicle to enter the series mode. In the series mode, the engine and the wheels are decoupled. At this time, the engine speed is not limited by the vehicle speed.

[0054] Step S133, for the case where the second comparison result indicates that the currently obtained vehicle speed is greater than the second vehicle speed threshold, control the whole vehicle to enter the parallel mode.

[0055] Exemplarily, when the currently obtained vehicle speed is greater than 70 kilometers per hour, control the whole vehicle to enter the parallel mode. In the parallel mode, the engine is coupled with the wheels and directly drives the wheels.

[0056] It can be understood that Step S132 and Step S133 respectively represent different steps executed based on different comparison results, and there is no sequential order in execution.

[0057] The above method compares the currently obtained vehicle speed with the second vehicle speed threshold in real time to obtain the second comparison result; for the case where the second comparison result indicates that the currently obtained vehicle speed is less than or equal to the second vehicle speed threshold, control the whole vehicle to enter the series mode; for the case where the second comparison result indicates that the currently obtained vehicle speed is greater than the second vehicle speed threshold, control the whole vehicle to enter the parallel mode, realizing the control of the whole vehicle to enter the series or parallel mode according to the second vehicle speed threshold, thereby accurately controlling the operating point of the engine, ensuring the functional efficiency of the whole vehicle, scientifically planning the working period of the engine, and reducing the energy consumption of the whole vehicle.

[0058] Optionally, the method further includes: in the series mode, the engine drives the range extender to generate electricity to supplement the power of the vehicle's battery.

[0059] Exemplarily, in the series mode, the engine can drive the range extender generator controller (GCU) to generate electricity. At this time, the driving energy of the whole vehicle comes from the power generation of the range extender, and the remaining driving energy can be charged back to the battery pack to supplement the power of the whole vehicle battery. The above method realizes the simultaneous power supply operation for the vehicle battery while the motor drives the range extender to work by driving the range extender to generate electricity in the series mode, improving the charging efficiency of the whole vehicle and enhancing the user experience.

[0060] Optionally, the method further includes: in the parallel mode, the engine drives the motor to generate electricity to supplement the power of the vehicle's battery.

[0061] Exemplarily, in the parallel mode, the engine and the motor jointly drive the wheels to accelerate. Specifically, the front axle of the whole vehicle can directly drive the output torque to the wheel end by the engine, and the rear axle of the whole vehicle is driven by the intervention of the motor while charging the vehicle's battery. By the above method, in the parallel mode, the engine drives the motor to generate electricity to charge the vehicle's battery, improving the charging efficiency of the whole vehicle while ensuring the best power performance of the whole vehicle.
