Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a vehicle engine power generation control method, device, equipment and storage medium. Background Art

[0002] With the guidance of fuel consumption regulations and national policies, extended-range electric vehicles have gradually become the development focus of major manufacturers. Extended-range electric vehicles have both electrical energy and petrochemical energy. They can be driven by battery power without starting the engine, or they can be driven by electricity after generating electricity with fuel. Based on this feature, hybrid vehicles face the problem of energy distribution: use oil first or electricity first or a mixture of oil and electricity. The strategies of various companies are similar. The problem of energy use distribution is reflected in the final remaining battery power. If electricity is used first and then oil, the power SOC will be consumed to a lower level, such as 15%, and then the engine will be started to generate electricity, and the power will no longer decrease; use oil first and then electricity, which means that the engine will start when the power is higher, such as 70%, and oil will be used first to generate electricity, and the power will not decrease; the strategies of various manufacturers are roughly the same, setting a power balance point. When it is higher than the balance point, it runs in pure electric mode. When it is lower than the balance point, the engine starts to work. Whether to use oil first or electricity first or a mixture of oil and electricity can be controlled by setting different power balance points. For example, 15% and 70% in the above example. In addition, some manufacturers have a power conservation mode, where users can set the desired balance power and the control is the same.

[0003] In the range-extended vehicle power generation control, the engine does not directly drive the full-range series power generation. The power generation / speed selection is based on the engine's optimal economic point to ensure the best fuel economy. This control mode means that if you want to increase the power generation, you can only increase the engine speed and torque to increase the power generation and increase the engine speed torque; reduce the power generation and reduce the engine speed torque. Based on the control of the power balance point of different energy modes, the power balance point means that the power needs to be kept near the balance point. The power generation of the engine needs to ensure that when the power is low, the power generation is increased, and when the power is high, the power generation is reduced to ensure that the power is always kept near the set target. In order to cope with extreme road conditions (continuous climbing, etc.), the minimum power of each mode is usually set. When the power deviates from the minimum power, high power output is required to ensure power maintenance. For example, when the balance point is 15%, when the power drops below 10% during the climbing process, the power generation will increase to prevent further decline. Similarly, in the mode with a balance point of 70%, the power generation needs to be increased to prevent further decline when the power drops below 60%. Based on the above control, the target balanced power can be maintained well, but it brings a problem. When the mode is switched, due to the different balanced power of each mode, after the mode is switched, the control system believes that there is a large gap between the current power and the target power, and will charge at the maximum power conservation power, which will cause NVH high-speed complaints.

DETAILED DESCRIPTION

[0021] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0022] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The main solution of the embodiment of the present application is: when the engine power generation control function is started, the current power of the target vehicle is obtained; the current virtual balance power is obtained according to the current power; and the engine power generation power of the target vehicle is controlled according to the current virtual balance power and the real balance power.

[0024] In this embodiment, for the convenience of description, the following description is made by taking the identification of the vehicle engine power generation control device as the execution subject.

[0025] Due to the existing technology of extended-range vehicle power generation control, the engine does not directly drive the full-range series power generation. The selection of power generation / speed is based on the engine's optimal economic point to ensure the optimal fuel economy. This control mode means that if you want to increase the power generation, you can only increase the engine speed and torque to increase the power generation and increase the engine speed torque; reduce the power generation and reduce the engine speed torque. Based on the control of the power balance point of different energy modes, the power balance point means that the power needs to be kept near the balance point. The power generation of the engine needs to ensure that when the power is low, the power generation is increased, and when the power is high, the power generation is reduced to ensure that the power is always kept near the set target. In order to cope with extreme road conditions (continuous climbing, etc.), the minimum power of each mode is usually set. When the power deviates from the minimum power, high power output is required to ensure power maintenance. For example, when the balance point is 15%, when the power drops below 10% during the climbing process, the power generation will increase to prevent further decline. Similarly, in the mode with a balance point of 70%, the power generation needs to be increased to prevent further decline when the power drops below 60%. Based on the above control, the target balanced power can be maintained well, but it brings a problem. When the mode is switched, due to the different balanced power of each mode, after the mode is switched, the control system believes that there is a large gap between the current power and the target power, and will charge at the maximum power conservation power, which will cause NVH high-speed complaints.

[0026] The present application provides a solution. When the engine power generation control function is started, the current virtual balance power is set according to the current power. The current balance power changes with the current power. The engine power generation power of the target vehicle is controlled according to the current virtual balance power and the real balance power. This avoids the power difference between the current power and the real balance power being too large, and the engine power generation power continues to work and charge at the maximum power maintenance power, resulting in NVH high-speed complaints. Controlling the engine power generation power can ensure both power and NVH.

[0027] It can be seen from the above embodiments that the present application discloses a vehicle engine power generation control method, device, equipment and storage medium, which relates to the field of vehicle control technology, and discloses a vehicle engine power generation control method, including: when the engine power generation control function is started, obtaining the current power of the target vehicle; obtaining the current virtual balance power according to the current power; controlling the engine power generation of the target vehicle according to the current virtual balance power and the real balance power; this method sets the current virtual balance power according to the current power when the engine power generation control function is started, and the current balance power changes with the current power, and controls the engine power generation of the target vehicle according to the current virtual balance power and the real balance power, so as to avoid the power difference between the current power and the real balance power being too large, and the engine power generation power continues to work and charge at the maximum power maintenance power, resulting in NVH high speed complaints, and controlling the engine power generation power can ensure both power and NVH.

[0028] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle engine power generation control device, etc. The following takes the vehicle engine power generation control device as an example to illustrate this embodiment and the following embodiments.

[0029] Based on this, the embodiment of the present application provides a vehicle engine power generation control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle engine power control method of the present application.

[0030] In this embodiment, the vehicle engine power generation control method includes steps S10 to S40: Step S10, when the engine power generation control function is started, the current power of the target vehicle is obtained.

[0031] It is understandable that the engine power generation control function is a function of setting a virtual balance power based on the current power, and the engine power generation can be effectively controlled based on this function.

[0032] It is understandable that the current power level may be the real-time power level of the battery of the range-extended vehicle.

[0033] In a feasible implementation manner, step S10 may include steps A101 to A103: Step A101, obtaining the last moment's balanced power and the current real balanced power.

[0034] It is understandable that the balance power corresponding to different energy modes of the vehicle is not the same. When the user switches the vehicle mode based on the vehicle function requirements, the corresponding vehicle balance power will change.

[0035] It is understandable that the change in vehicle balance charge caused by the change in front and rear modes may be large or small.

[0036] In specific implementation, when the mode is switched, due to the different balanced power levels of each mode, for example, from the 15% mode, manually switching to the 70% balance point mode, because the current power level is around 15%, which is far below the minimum power level of the 70% balance point, the manual setting is similar, setting a higher target power level (70%) from the current low power level (15%). After the mode is switched, the control system believes that there is a large gap between the current power level and the target power level.

[0037] It should be understood that whether the mode switching causes a large balance power difference, the balance power at the last moment and the current real balance power can be continuously monitored to determine whether the mode switching causes a large balance power difference.

[0038] Step A102, obtaining a balanced power difference according to the balanced power at the last moment and the current real balanced power.

[0039] It is understandable that the absolute value of the last moment's balance power minus the current real balance power may be used as the balance power difference.

[0040] Step A103, when the balance power difference is greater than a preset power threshold, the engine power generation control function is started.

[0041] It is understandable that the preset power threshold can be a balance power difference threshold set in advance based on experience. Simply put, if the power difference between the current actual balance power and the balance power at the previous moment is greater than the balance power difference threshold, the engine's power generation power will cause NVH abnormalities.

[0042] It should be noted that the preset power threshold may be 30%, 40%, 50% of the total power, etc., and may be set based on actual experience or experimental conditions, and this embodiment does not limit this.

[0043] In the specific implementation, the balancing power data is monitored. If the current balancing power SOC_Target-the balancing power SOC_Target saved in the previous calculation cycle>threshold A, A>0, it is judged that the target balancing power has jumped (mode switching / manually increasing the target power), and the virtual balancing power control (i.e., the engine power generation control function) is activated.

[0044] In this embodiment, the balance power difference is used as a limiting condition for starting the engine power generation control function, which can avoid unnecessary activation of this function when the balance power difference is small, thereby occupying the running space of other vehicle programs.

[0045] The above are only feasible implementations of step S10 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S10.

[0046] Step S20, obtaining the current virtual balanced power according to the current power.

[0047] It should be noted that the current virtual balance power is a virtual value set according to the current power. Its function is to enable the engine to generate electricity according to the power difference between the current power and the balance power. Power generation based on this power difference can make the engine at the optimal economic point of the engine, thereby ensuring the optimal fuel economy for power generation.

[0048] Step S30, controlling the engine power generation of the target vehicle according to the current virtual balance power and the real balance power.

[0049] It is understandable that in the extended-range vehicle power generation control, the engine does not directly drive the full-range series power generation, and the selection of power generation power / speed is based on the engine's optimal economic point to ensure optimal fuel economy. This control mode means that if you want to increase the power generation power, you can only increase the engine speed and torque to increase the power generation power and increase the engine speed and torque; reduce the power generation power and reduce the engine speed and torque.

[0050] It should be understood that the engine's power generation is affected by the difference between the actual power and the balanced power. If the power difference is too large, in order to ensure that the battery power quickly meets the balanced power, the power generation will be increased, that is, the engine speed will be increased, resulting in NVH abnormalities.

[0051] In a feasible implementation, step S30 may include steps A41 to A32: Step A31, comparing the current virtual balance power and the real balance power to obtain a comparison result.

[0052] It is understandable that the comparison result may be that the current virtual balance power is less than the real balance power, or the current virtual balance power is greater than or equal to the real balance power.

[0053] Step A32, controlling the engine power generation of the target vehicle based on the comparison result.

[0054] It should be noted that, when the comparison result is that the current virtual balance power is less than the real balance power, the engine power generation power of the target vehicle is controlled according to the current virtual balance power; when the comparison result is that the current virtual balance power is greater than or equal to the real balance power, the engine power generation power of the target vehicle is controlled based on the current real balance power and the engine power generation power control function is turned off.

[0055] In the specific implementation, the power generation target control based on power conservation takes the balanced target SOC (70%) as the base point, and sets different power conservation powers according to the deviation between the current SOC and the target. Different power generation powers are used to cope with different driving conditions (flat road, downhill, small climbing, overtaking, large climbing, high temperature climbing, plateau climbing, etc.). The power generation control schematic diagram after the engine mode switching in the prior art can be referred to Figure 2 The schematic diagram of engine power control based on virtual balance power in this embodiment can be referred to Figure 3 , Figure 3 The virtual balance power calls a fixed deviation based on the current SOC to ensure NVH and low-power charging at the same time; the virtual balance power gradually increases with the current SOC and exits control after it is greater than the actual target SOC.

[0056] In this embodiment, the virtual balance power is set by the current power to achieve the control power difference to control the engine power generation power, and the virtual balance power and the real balance power are continuously compared. When the real balance power is greater than or equal to the virtual balance power, the power difference is directly calculated based on the real balance power to control the engine power.

[0057] The above are only feasible implementations of step S30 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S30.

[0058] The present embodiment provides a vehicle engine power generation control method. When the engine power generation control function is started, the current virtual balance power is set according to the current power. The current balance power changes with the current power. The engine power generation of the target vehicle is controlled according to the current virtual balance power and the real balance power. This avoids a large power difference between the current power and the real balance power. The engine power generation continues to charge at the maximum power maintenance power, causing NVH high speed complaints. Controlling the engine power generation can ensure both power and NVH.

[0059] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 4 In the vehicle engine power generation control method, step S20 further includes steps S21 to S23: Step S21, obtaining a preset adjustment ratio.

[0060] It is understandable that the preset adjustment ratio may be a ratio in which the virtual balance power is set higher than the current power.

[0061] It should be understood that the preset adjustment ratio may be an upward adjustment ratio value set based on experience, and the power difference between the virtual balance power and the current power obtained based on the preset adjustment ratio can make the engine power generation at a more economical power generation.

[0062] Step S22, obtaining a reference balanced power according to the current power and a preset adjustment ratio.

[0063] It should be noted that the current power level plus the total battery power level with a preset adjustment ratio can be used as a reference balancing power level.

[0064] In specific implementation, when the preset adjustment ratio is 4% and the current power is 10%, the reference balance power is 10% + 4%. In simple terms, the virtual balance power = current SOC + 4% (calibrable and adjustable). The virtual balance power is 4% larger than the current SOC. A virtual deviation of 4% is created to control the power generation power. The power generation power of this deviation must be met, and it can be charged under normal road conditions and the NVH is acceptable.

[0065] Step S23, obtaining the current virtual balanced power according to the reference balanced power.

[0066] It is understandable that the reference balance power is calculated based on the current battery power. Although the engine is continuously generating electricity, when it suddenly encounters large resistance (climbing a hill, etc.) during the power generation process, the current power generation power cannot meet the demand and the power will drop.

[0067] It should be understood that because the current power may decrease, when the current power decreases, the corresponding calculated reference balance power will become smaller. In this case, the reference balance power calculated from the current power cannot be directly used as the current virtual balance power.

[0068] In a feasible implementation, step S23 may include steps A231-A232: Step A231, obtaining the virtual balance power at the last moment.

[0069] It is understandable that the virtual balance power at the last moment may be calculated based on the power at the last moment and a preset adjustment ratio, or the virtual balance power at the last moment may be maintained as the virtual balance power at the last moment.

[0070] Step A232, obtaining the current virtual balance power according to the virtual balance power at the previous moment and the reference virtual balance power.

[0071] It should be noted that when the virtual balance power at the previous moment is less than or equal to the reference virtual balance power, the reference virtual balance power is used as the current virtual balance power; when the virtual balance power at the previous moment is greater than the reference virtual balance power, the virtual balance power at the previous moment is used as the current virtual balance power.

[0072] It should be further explained that the virtual balance power only increases and does not decrease. After the current SOC drops, the virtual balance power maintains the current value. The deviation between the current SOC and the virtual balance power is greater than 4%. For example, if it expands to 6%, power generation will be carried out with a 6% deviation. If power continues to be lost, the power generation capacity will be increased by 7%, 8%, 9%, and 10% according to the deviation to maintain power supply.

[0073] In the specific implementation, the current virtual balance power is maintained ≥ the virtual balance power at the previous moment, that is, the virtual target SOC can only increase with the increase of the current power, and cannot decrease with the decrease of the current power. When a large resistance (climbing, etc.) is suddenly encountered during the power generation process, the current power generation cannot meet the demand, and the power will drop. At this time, the virtual target SOC does not decrease and keeps the current value unchanged. At this time, because of the decrease in the current power, the value of virtual balance power-current SOC>4%, which triggers a larger deviation power generation control, the deviation expands, and the power generation increases accordingly.

[0074] It can be understood that when the virtual balance power ≥ the real balance power (the current virtual balance power ≥ the current real balance power), the engine power generation control function is exited. That is, when the virtual balance power reaches or exceeds the real balance power as the current power increases, the power generation control is performed with the real target balance power.

[0075] In this embodiment, when the current virtual balance power is calculated by the current power, it is further compared with the virtual balance power at the previous moment to maintain the current virtual balance power ≥ the virtual balance power at the previous moment. When the current virtual balance power is less than the virtual balance power at the previous moment, the previous moment is used as the current virtual balance power to avoid a decrease in starting power due to a decrease in virtual balance power, which makes it impossible to guarantee the battery power.

[0076] The above are only feasible implementations of step S23 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S23.

[0077] The present embodiment provides a vehicle engine power generation control method. By presetting an adjustment ratio, a virtual balance power is obtained by adding the preset adjustment ratio to the current power. The power difference between the current power and the virtual balance power can be effectively controlled, thereby controlling the engine power generation to maintain a level that can ensure that the battery power can support vehicle driving, while ensuring that the engine power generation does not cause NVH abnormalities under the power difference.

[0078] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle engine power generation control method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.
