Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to a vehicle parking charging control method, device, control equipment, and storage medium. Background Technology

[0002] In the field of hybrid electric vehicle technology, the hybrid system of a vehicle consists of a power battery, a range extender system composed of a direct-connected engine and generator, and a drive motor. The vehicle's driving methods include pure electric drive, series drive, and parallel drive. In scenarios where an external discharge gun is used for external discharge, such as camping or barbecuing, or in parking scenarios where the power battery's SOC (State of Charge, also known as remaining charge) is low, a parking charging mode can be activated. When the parking charging mode is activated, the power battery can be charged.

[0003] Currently, because vehicles cannot automatically adjust the charging level in parking charging mode, it can easily affect the user experience. For example, in some special scenarios, such as when the power battery is supplying power to an external source (e.g., an induction cooker) while the air conditioner is being used inside the vehicle, the charging power during parking may be less than the discharging power, making it impossible to maintain the power battery's SOC near the user-specified target value, leading to user complaints. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a vehicle parking charging control method, device, control equipment and storage medium, which can improve the problem that the vehicle cannot automatically adjust the charging level in the parking charging mode.

[0005] To achieve the above technical objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, embodiments of this application provide a vehicle parking charging control method, the method comprising:

[0007] When a charging request to activate the parking charging mode is received, and the vehicle meets the preset charging conditions, the initial charging level is obtained.

[0008] According to the initial charging level, control the operation of the vehicle's engine and generator to charge the vehicle's power battery;

[0009] During the charging of the power battery, the remaining power of the power battery is collected at preset timing intervals;

[0010] The target charging level for the current timing cycle is determined based on the difference between the remaining charge of the power battery in the current timing cycle and the remaining charge in the previous N timing cycles, where N is an integer greater than or equal to 1.

[0011] During the current timing cycle, the engine and the generator are controlled to operate according to the target charging level in order to charge the power battery.

[0012] In conjunction with the first aspect, in some optional embodiments, the method further includes, before obtaining the initial charging level:

[0016] If the vehicle is not in the drivable state and not in the external discharge state, or is not in the parking gear, or the remaining amount of fuel in the engine of the vehicle is less than the preset threshold, or the remaining charge of the power battery is greater than or equal to the first preset charge, it is determined that the vehicle does not meet the preset charging conditions.

[0017] In conjunction with the first aspect, in some optional implementations, obtaining the initial charging level includes:

[0018] Receive the charging level input by the user as the initial charging level;

[0019] Alternatively, a pre-stored specified charging level can be obtained as the initial charging level.

[0020] In conjunction with the first aspect, in some optional embodiments, during the charging of the power battery, the remaining power of the power battery is collected at preset timing intervals, including:

[0021] When charging the power battery begins, the remaining power of the power battery is collected at each time interval of the timing cycle;

[0022] During the charging of the power battery, if the number of times the remaining power of the power battery is collected is greater than or equal to 1+N, then the remaining power of the power battery in the current timing cycle and the remaining power in the previous N timing cycles are stored and recorded.

[0023] In conjunction with the first aspect, in some optional implementations, the target charging level for the current timing cycle is determined based on the difference between the remaining charge of the power battery in the current timing cycle and the remaining charge in the previous N timing cycles, where N is an integer greater than or equal to 1, including:

[0024] When the power difference is less than or equal to the second preset power, and the charging level in the (i-1)th timing cycle is not the level with the maximum charging power, and the current timing cycle is the i-th timing cycle, then any charging level with a charging power greater than that in the (i-1)th timing cycle is determined as the target charging level in the current timing cycle, where i takes integer values ​​greater than or equal to 2. When i = 2, the charging level in the (i-1)th timing cycle is the initial charging level.

[0025] When the power difference is greater than the second preset power, and the current timing period is the i-th timing period, then the charging level of the (i-1)-th timing period is taken as the target charging level of the current timing period.

[0026] In conjunction with the first aspect, in some alternative implementations, the method further includes:

[0027] When the vehicle does not meet the preset charging conditions, the generator is controlled to stop charging the power battery.

[0028] Secondly, embodiments of this application also provide a vehicle parking charging control device, the device comprising:

[0033] The second control unit is used to control the engine and the generator to charge the power battery according to the target charging level during the current timing cycle.

[0036] The invention employing the above technical solution has the following advantages:

[0037] In the technical solution provided in this application, during the charging of the power battery in the parking charging mode, the remaining power battery charge is collected at preset timing cycles. Based on the difference between the remaining power battery charge in the current timing cycle and the remaining power battery charge in the previous N timing cycles, the target charging level for the current timing cycle is determined. Based on the target charging level, the engine and generator are controlled to operate to charge the power battery.

[0043] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In the description of this application, terms such as "first" and "second" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] This application provides a control device that can be deployed on a vehicle for automatic control of charging in parking charging mode. The vehicle includes a hybrid power system comprising a power battery, a range extender system consisting of a power battery, an engine and a generator directly connected together, and a drive motor.

[0045] The control device may include a processing module and a storage module. The storage module stores a computer program, which, when executed by the processing module, enables the control device to perform the corresponding steps in the vehicle parking charging control method described below.

[0046] It should be noted that the control equipment can be existing hardware on the vehicle, which can reduce hardware costs.

[0047] Please refer to Figure 1 This application also provides a vehicle parking charging control method, which can be applied to the aforementioned control device and can be executed or implemented by the control device. The vehicle parking charging control method may include the following steps:

[0048] Step 110: When a charging request to activate the parking charging mode is received and the vehicle meets the preset charging conditions, the initial charging level is obtained.

[0049] Step 120: According to the initial charging level, control the engine and generator of the vehicle to operate in order to charge the power battery of the vehicle;

[0050] Step 130: During the charging of the power battery, the remaining power of the power battery is collected at a preset timing period;

[0051] Step 140: Determine the target charging level for the current timing cycle based on the difference between the remaining charge of the power battery in the current timing cycle and the remaining charge in the previous N timing cycles, where N is an integer greater than or equal to 1.

[0052] Step 150: During the current timing cycle, the engine and the generator are controlled to operate according to the target charging level in order to charge the power battery.

[0053] The steps of the vehicle parking charging control method will be explained in detail below:

[0054] Prior to step 110, the method may further include:

[0055] Determine whether the vehicle meets the preset charging conditions.

[0056] The preset charging adjustment can be flexibly determined according to actual conditions. For example, determining whether the vehicle meets the preset charging conditions may include:

[0057] If the vehicle is in a drivable state or in a state of external discharge, and is in the parking gear, and the remaining amount of fuel in the engine of the vehicle is greater than or equal to a preset threshold, and the remaining charge of the power battery is less than a first preset charge, then the vehicle is determined to meet the preset charging conditions.

[0058] If the vehicle is not in the drivable state and not in the external discharge state, or is not in the parking gear, or the remaining amount of fuel in the engine of the vehicle is less than the preset threshold, or the remaining charge of the power battery is greater than or equal to the first preset charge, it is determined that the vehicle does not meet the preset charging conditions.

[0059] In this embodiment, the detection methods for whether the vehicle is in a "drivable state," "external discharge state," and "parking gear" are conventional and will not be elaborated further. Drivable state can be understood as the vehicle being able to drive normally. External discharge state can be understood as the power battery being connected to a discharge gun, supplying power to the outside world through the discharge gun; for example, the power battery supplying power to an induction cooker via the discharge gun. Parking gear can be understood as the vehicle being in P gear.

[0060] Engine fuel can be, but is not limited to, gasoline, liquefied natural gas, etc. The corresponding preset threshold can be flexibly set according to actual conditions. This preset threshold is a critical value used to measure whether the remaining fuel is sufficient. For example, the preset threshold can be 50% of the total. For instance, if the vehicle's remaining fuel is less than 50% of the total, it means that the vehicle does not meet the preset charging conditions.

[0061] In this embodiment, the remaining charge of the power battery can be abbreviated as SOC, which stands for State of Charge. If the remaining charge is sufficient, the vehicle does not need to enter the parking charging mode to charge the power battery. That is, if the remaining charge of the power battery is greater than or equal to a first preset charge level, it means that the vehicle does not meet the preset charging conditions and is not allowed to enter the parking charging mode. The first preset charge level can be flexibly set according to the actual situation, for example, it can be 80% of the full charge of the power battery.

[0062] Understandably, when determining the preset charging conditions, if any condition is not met, it means that the vehicle does not meet the preset charging conditions.

[0063] In step 110, obtaining the initial charging level may include:

[0064] Receive the charging level input by the user as the initial charging level;

[0065] Alternatively, a pre-stored specified charging level can be obtained as the initial charging level.

[0066] In this embodiment, the user can manually input a charging level through the vehicle's central control display screen or an APP on a mobile terminal bound to the vehicle, and this charging level can be used as the initial charging level.

[0067] In addition, the control device can also pre-store a specified charging level, which can then be used as the initial charging level. This specified charging level can be the default charging level configured by the engineer, or the last used charging level, and can be flexibly set according to actual needs.

[0068] Generally speaking, for the same model of engine and generator, the higher the charging power, the greater the noise generated by the engine and its operation. Therefore, the initial charging level is usually a relatively low charging power level to reduce charging noise. For example, if the charging levels are divided into low, medium, and high levels, with the corresponding charging power increasing sequentially, then the initial charging level can be low.

[0069] When the vehicle meets the preset charging conditions, it proceeds to step 120. In this step, engineers have pre-calibrated a first correspondence between different charging levels and the charging power output of the generator. Additionally, they have pre-calibrated a second correspondence between the generator's output power and the engine's speed / torque. Based on this, in step 120, the control device can automatically control the engine and generator to operate according to the current initial charging level to charge the power battery, wherein the generator's output charging power is matched to the current charging level.

[0070] In step 130, during the charging of the power battery, the remaining power of the power battery is collected at preset timing intervals, including:

[0071] When charging the power battery begins, the remaining power of the power battery is collected at each time interval of the timing cycle;

[0072] During the charging of the power battery, if the number of times the remaining power of the power battery is collected is greater than or equal to 1+N, then the remaining power of the power battery in the current timing cycle and the remaining power in the previous N timing cycles are stored and recorded, where N is an integer greater than or equal to 1, which can be flexibly determined according to the actual situation.

[0073] In this embodiment, the duration of a timing period T can be flexibly set according to actual conditions, and is usually a shorter duration. For example, a timing period can be 30 seconds, 1 minute, 2 minutes, etc. Additionally, as an example, the previous N timing periods refer to the previous timing period of the current timing period.

[0074] As an example, step 130 can be implemented as follows:

[0075] When charging the power battery begins, its current State of Charge (SOC) is collected as the initial SOC measurement. Then, using the moment of the initial measurement as the starting point, the actual SOC of the power battery is collected every time interval (time cycle). In parking charging mode, the actual SOC of the power battery at time t0, when the engine starts successfully, can be stored and recorded. Act After one timing period T, time t1 is reached. At this time, the SOC is updated using the SOC at time t1. Act At the same time, the SOC is updated using the SOC at time t0. Act_Last After two timing cycles, time t2 is reached. At time t2, the SOC is updated using the SOC at time t2. Act And update the SOC using the SOC at time t1. Act_Last Similarly, after the j-th timing cycle, t is reached. j At that moment, in t j At time t, use t j SOC updates in real time Act and the use of t j-1 SOC updates in real time Act_Last j takes integers greater than or equal to 3, until the collected SOC of the power battery reaches the target SOC for parking charging (e.g., the first preset charge level), at which point the engine stops or exits the parking charging mode. Thus, for the collected SOC, the control device can store only two data points: the SOC of the power battery in the current timing cycle (i.e., the SOC value). Act ) and the SOC in the previous timing cycle (i.e., SOC) Act_Last ).

[0076] In step 140, the target charging level for the current timing cycle is determined based on the difference between the remaining charge of the power battery in the current timing cycle and the remaining charge in the previous N timing cycles, where N is an integer greater than or equal to 1, and may include:

[0077] When the power difference (denoted as ΔSOC) Chrg The SOC (State of Charge) is less than or equal to the second preset charge level. Thrsh ), and the charging level in the (i-1)th timing cycle is not the level with the maximum charging power, and when the current timing cycle is the i-th timing cycle, then any level with a charging power greater than the charging level in the (i-1)th timing cycle is determined as the target charging level in the current timing cycle, where i takes integer values ​​greater than or equal to 2 in sequence, and when i = 2, the charging level in the (i-1)th timing cycle is the initial charging level;

[0078] When the power difference is greater than the second preset power, and the current timing period is the i-th timing period, then the charging level of the (i-1)-th timing period is taken as the target charging level of the current timing period.

[0079] In this embodiment, the second preset power level can be flexibly set according to the actual situation. The second preset power level can be used to represent the critical value of whether the power battery has been charged with enough power within a timing cycle.

[0080] If the power difference ΔSOC Chrg Less than or equal to the second preset SOC Thrsh If the parking charger fails to charge the battery sufficiently within a given time period, the charging level can be increased by one or more levels to boost charging power. Step 140 is executed once per time period, and the charging level is increased when the conditions for increasing the level are met, continuing until the maximum charging power level is reached. That is, once the maximum charging power level is reached, no further increase in charging power is required in the next time period.

[0081] If the power difference ΔSOC Chrg Greater than the second preset SOC Thrsh This indicates that the parking charging mode has already charged the battery to a sufficient level within one timing cycle, and there is no need to adjust the parking charging mode; the charging level from the previous timing cycle can be maintained. If the previous timing cycle was the first timing cycle, then this charging level is the initial charging level.

[0082] It should be noted that, in other embodiments, the power difference can be the SOC difference of the power battery at intervals of two or more timing cycles.

[0083] In step 150, the control device can automatically control the operation of the engine and generator according to the currently determined target charging level, so that the charging power of the generator matches the target charging level. It should be noted that the implementation process of step 150 is similar to that of step 120, and will not be described again here.

[0084] In this embodiment, the method may further include:

[0085] When the vehicle does not meet the preset charging conditions, the generator is controlled to stop charging the power battery.

[0086] During parking charging, if the vehicle does not meet the preset charging conditions, or if the user inputs a command to end charging via the vehicle's central control display or a mobile app, the control device will, based on this command, control the engine and generator to stop operating, thereby ending the charging of the power battery. The vehicle not meeting the preset charging conditions can be due to any of the following conditions:

[0087] 1) The vehicle is not in a drivable state and is not discharging power.

[0088] 2) Not in park;

[0089] 3) The remaining amount of fuel in the vehicle's engine is less than a preset threshold;

[0090] 4) The remaining power of the power battery is greater than or equal to the first preset power.

[0091] Please refer to Figure 2 As an example, the implementation process of the method will be illustrated below:

[0092] S1, the user selects the parking charging mode so that the control device can receive the charging request to activate the parking charging mode.

[0093] S2, the control device determines whether the (preset) conditions for the parking charging mode are met;

[0094] S3: If the preset conditions are not met, the driving mode will remain unchanged.

[0095] S4. If the preset conditions are met, the vehicle will enter the parking charging mode and obtain the charging mode gear information (i.e., the initial charging gear).

[0096] S5: After the engine starts successfully, the current SOC of the power battery is recorded after each timing cycle.

[0097] S6 determines whether the SOC of the power battery increases within a certain period of time (usually a timing cycle);

[0098] S7: If the SOC of the power battery increases, the parking charging level will remain unchanged.

[0099] For S8, if the SOC of the power battery does not increase, adjust the parking charging level to one level higher.

[0100] The S9 matches the parking charging power based on the final parking charging level (i.e. the target charging level) to charge the power battery.

[0101] In this embodiment, the control device can match the charging power according to the parking charging level. That is, in the parking charging mode, the parking charging power is matched based on the charging level adjusted according to the actual charging situation. For example, the three parking charging modes of high, medium and low each correspond to a charging power, which is the engine power generation power and can be calibrated.

[0102] In parking charging mode, by monitoring the actual charging situation, if the SOC increase of the power battery fails to reach the expected SOC over a long period of time, the parking charging level will be automatically increased to avoid functional failure in special usage scenarios, improve system robustness, meet the user's power supply needs, and enhance the user's driving experience.

[0103] Please refer to Figure 3 This application also provides a vehicle parking charging control device 200, which includes at least one software function module that can be stored in a storage module or embedded in the operating system (OS) of the control device in the form of software or firmware. A processing module is used to execute executable modules stored in the storage module, such as the software function modules and computer programs included in the vehicle parking charging control device 200.

[0104] The functions of each unit included in the vehicle parking charging control device 200 can be as follows:

[0105] The acquisition unit 210 is used to acquire the initial charging level when it receives a charging request to activate the parking charging mode and the vehicle meets the preset charging conditions.

[0107] The acquisition unit 230 is used to acquire the remaining power of the power battery at a preset timing period during the charging of the power battery.

[0108] The determining unit 240 is used to determine the target charging level of the current timing cycle based on the difference between the remaining charge of the power battery in the current timing cycle and the remaining charge in the previous N timing cycles, where N is an integer greater than or equal to 1.

[0119] Optionally, the determining unit 240 can be used for:

[0120] When the power difference is less than or equal to the second preset power, and the charging level in the (i-1)th timing cycle is not the level with the maximum charging power, and the current timing cycle is the i-th timing cycle, then any charging level with a charging power greater than that in the (i-1)th timing cycle is determined as the target charging level in the current timing cycle, where i takes integer values ​​greater than or equal to 2. When i = 2, the charging level in the (i-1)th timing cycle is the initial charging level.

[0121] When the power difference is greater than the second preset power, and the current timing period is the i-th timing period, then the charging level of the (i-1)-th timing period is taken as the target charging level of the current timing period.
