[0063] The terms "first" and "second" in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "comprising" and any of their variations are intended to cover non-exclusive protection.

"Multiple" in the present application can mean at least two, for example, two, three or more, and the embodiments of the present application are not limited.

[0064] The control method of the range extender provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. After receiving the driving instruction, the terminal 102 can query the battery status information in real time, and receive the vehicle speed distribution information sent by the server 104 through the network; or, receive the real-time traffic information of the designated road section sent by the server 104 through the network, and predict the vehicle speed distribution information in combination with the historical traffic information of the designated road section, so as to determine the amount of power required to be provided by the range extender. Then, the working time of the range extender can be determined accordingly, so that the range extender works according to the working time.

[0065] The terminal 102 may be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0066] In one embodiment, Figure 2 As shown, a control method for a range extender is provided, and the method is applied to Figure 1 The terminal in is used as an example to illustrate, including the following steps:

[0067] Step 201, in response to receiving a driving instruction, querying battery status information and determining vehicle speed distribution information.

[0068] The driving instruction includes a designated road section. The designated road section is the road section that the vehicle passes through to the destination. The driving instruction may also include a departure time, an estimated arrival time, and a driving time composed of the departure time and the estimated arrival time.

[0069] The vehicle speed distribution information includes a corresponding relationship between a first vehicle speed and time when the vehicle passes through a designated road section.

[0070] Specifically, the aforementioned vehicle speed distribution information may be the vehicle speed change information obtained by planning based on the departure time input or selected by the user, combined with the real-time traffic information of the designated road section and the historical traffic information of the designated road section during the travel time.

[0071] Furthermore, the traffic information may include at least one of traffic volume, road congestion location, congestion duration, and traffic light information.

[0072] The real-time traffic information includes traffic information with a timestamp, which may correspond to the aforementioned departure time or a moment slightly earlier than the aforementioned departure time.

[0073] The historical traffic information may be the traffic information of a specified road section corresponding to the aforementioned departure time and estimated arrival time.

[0074] The battery status information at least includes the SOC of the battery.

[0075] Step 202: Determine a first power level of the range extender based on the status information.

[0076] Among them, the first power indication is the power required by the range extender for the vehicle to pass through a specified road section.

[0077] The first amount of electricity may also be referred to as the required amount of electricity of the range extender.

[0078] Specifically, the above-mentioned state information can reflect the amount of electricity that the battery can provide to the vehicle. Therefore, the first amount of electricity can be determined based on the above-mentioned state information and the second amount of electricity required to drive the vehicle through the specified road section.

[0079] The second amount of electricity may also be referred to as total required electricity.

[0080] Step 203: compare the first vehicle speed with a preset first threshold to determine the working time of the range extender.

[0081] The working time includes multiple working time periods, and each working time period is composed of a start time and a stop time.

[0082] For details, please refer to Figure 3When the vehicle is driving on a designated road section, the range extender will start and stop according to the working time period to generate electricity for the vehicle.

[0083] Step 204 , taking the first power amount as the power generation target, controlling the range extender to operate according to the aforementioned working time.

[0084] In the control method of the range extender, the working target of the range extender: the first power level is determined by the vehicle speed distribution information and the battery status information queried in real time; then, the start and stop time of the range extender is determined by comparing the relative size of the first vehicle speed and the first threshold, thereby improving the NVH performance of the vehicle while ensuring that the vehicle executes the driving instructions, and avoiding the problems of insufficient safety and reduced driving comfort caused by poor NVH performance.

[0085] In one embodiment, the vehicle speed distribution information can be obtained by inputting the departure time, the above-mentioned real-time traffic information, and historical traffic information into a pre-trained deep learning model. The deep learning model can output the estimated arrival and other driving information accordingly.

[0086] An example of determining the first electrical quantity is provided below. Please refer to Figure 4 :

[0087] Step 401, according to the driving time in the driving instruction, obtain the traffic information of the aforementioned designated road section at the driving time.

[0088] Specifically, the driving instruction may be sent to the service cloud so that the service cloud can query the traffic information of the specified road section according to the driving time. In this way, the aforementioned traffic information can be obtained.

[0089] Step 402: Determine a second power level based on traffic information.

[0090] The second power indication is the power required to drive the vehicle through a specified road section.

[0091] The second amount of electricity can be obtained by inputting energy consumption information into a pre-trained second model. The energy consumption information includes at least one of the driving mode, the driver's driving habits, the aforementioned vehicle speed distribution information, and the temperature. And / or,

[0092] The average power consumption of the vehicle over a hundred kilometers in history may be obtained first, so as to calculate the product of the power consumption over the hundred kilometers in history, the mileage of the designated road section, and the third coefficient as the second power.

[0093] The third coefficient can be fine-tuned (increased or decreased) in combination with the aforementioned energy consumption information.

[0094] Exemplarily, in response to a high-speed section in the vehicle speed distribution information exceeding a preset threshold, the third coefficient is increased based on a preset first fine-tuning factor; in response to a low-speed section in the vehicle speed distribution information exceeding a preset threshold, the third coefficient is reduced based on a preset second fine-tuning factor.

[0095] In response to the accumulated time that the driving mode is in the power mode exceeding the first time threshold, the third coefficient is increased based on a preset third fine-tuning factor.

[0096] In response to the accumulated time during which the driving mode is in the economy mode exceeding a second time threshold, the third coefficient is reduced based on a preset fourth fine-tuning factor.

[0097] Step 403: Determine a third power level based on the status information.

[0098] Among them, the third power indicator is the power that the battery can provide when the vehicle passes through a specified road section.

[0099] Optionally, the SOC in the status information is directly determined as the third electrical quantity.

[0100] The above-mentioned state information may further include a first coefficient. In order to avoid damaging the health of the battery, in one embodiment, the product of the SOC in the state information and the first coefficient may be determined to be the above-mentioned third power. The first coefficient is less than 1.

[0101] Step 404: determine the first power level based on the difference between the second power level and the third power level.

[0102] Optionally, the difference between the second electrical quantity and the third electrical quantity may be directly determined as the first electrical quantity.

[0103] Alternatively, the difference between the second electric quantity and the third electric quantity may be multiplied by a second coefficient to obtain the first electric quantity. The second coefficient is greater than 1 and less than 1.5. The second coefficient may be, for example, 1.1.

[0104] Furthermore, when determining the working time of the range extender, in order to improve the NVH performance, the start time and stop time of the range extender can be determined by the relative size relationship between the first vehicle speed and the first threshold in the vehicle speed distribution information, and the corresponding relationship between the first vehicle speed and time in the vehicle speed distribution information. Specifically, in response to the first vehicle speed being greater than the preset first threshold, the time corresponding to the first vehicle speed is determined as the start time. And / or;

[0105] In response to the first vehicle speed being less than or equal to the first threshold, the time corresponding to the first vehicle speed is determined as the shutdown time. The time corresponding to the first vehicle speed can be obtained by querying the vehicle speed distribution information.

[0106] In this way, multiple groups of start-up times and stop-down times can be included in the driving time to constitute the working time.

[0107] In one embodiment, in order to make the power generation of the range extender on a specified road section correspond to the first power, the power of the range extender at each first vehicle speed can be further determined. Specifically, the pre-calibrated first power information and second power information can be first obtained. Among them, the first power information includes the first power corresponding to the first vehicle speed, and the first power is the vehicle driving power, that is, the power required to drive the vehicle.

[0108] The second power information includes a second power corresponding to the first vehicle speed, the second power being the power generated by the range extender that is less than a preset NVH threshold. Here, less than the preset NVH threshold indicates that it is also less than a noise threshold, a vibration threshold, and a sound vibration roughness threshold.

[0109] Then, the minimum value may be selected from the first power and the second power corresponding to the first vehicle speed as the third power.

[0110] Finally, the third power can be used as the power generation power of the range extender, so that the range extender operates based on the third power and the working time. That is, during the driving time, when the time is in the working time, the range extender is started, and the first speed of the vehicle during the working time is used to determine the third power corresponding thereto, so that the range extender outputs the third power during the working time to power the vehicle.

[0111] The pre-calibrated first power information and the pre-calibrated second power information are independent of each other. In addition, the pre-calibration is performed according to different vehicle models and different working conditions.

[0112] The following takes the first power as P a , the second power is P b , for the third power P c An example of determination is shown in Table 1.

[0113] Table 1

[0114]

[0115]

[0116] In the above speed ranges, P a Only the power required for vehicle driving (including the power required for air conditioning, etc.) is considered, and P b The power required by the vehicle is not considered, and only the NVH threshold is used as P b The two are independent of each other. a , P b The relative size relationship is not absolute. For example, corresponding to 0~V1, P a1 >P b1 , and corresponding to V3~V4, then P a1 <P b1 .

[0117] Furthermore, a preset conversion formula may be used to determine the rotation speed corresponding to the third power. During the working time, the range extender operates according to the rotation speed and the third power to supply power to the vehicle.

[0118] To further avoid the situation that the range extender may not be required to work at the corresponding first speed in the third power determined by the aforementioned method, in one embodiment, since the vehicle speed distribution information contains the correspondence between the first vehicle speed and time, and the third power corresponds to the first vehicle speed, the correspondence between the third power and time can be established based on the vehicle speed distribution information and the third power, thereby determining the power distribution information. Then the power distribution information includes the correspondence between the third power and time.

[0119] Next, the third power corresponding to the working time can be queried in the power distribution information according to the working time, and the third power corresponding to the working time can be determined as the target power.

[0120] The range extender is controlled based on the target power and working time to supply power to the vehicle.

[0121] Furthermore, in one embodiment, a fourth power quantity may be determined based on the vehicle speed distribution information and the third power. The fourth power quantity indicates the power quantity provided by the range extender based on the target power during the aforementioned working time. The fourth power quantity may also be referred to as the actual power supply quantity of the range extender.

[0122] In response to the first electrical quantity and the fourth electrical quantity being equal, it is determined that the power generation of the range extender meets the energy demand of the vehicle on the specified road section under the premise of improving NVH performance.

[0123] Alternatively, in response to the absolute value of the difference between the first power and the fourth power being greater than a third threshold, an optimization rule is determined, and the target power and / or working time is optimized based on the optimization rule. The third threshold may be 0, or slightly greater than 0, such as 0.5, or 1.0.

[0124] The optimization rule includes a first rule and / or a second rule.

[0125] The first rule indicates that a first time period is determined according to the power distribution information, and the first time period is deleted in the working time period to reduce the power generation of the range extender.

[0126] The second rule indicates that a second time period is determined according to the power distribution information, and a value of the target power in the second time period is increased to increase the power generation of the range extender.

[0127] In one embodiment, the working time period can be optimized according to the first rule: according to the power distribution information, the time corresponding to the third power of the first power is determined, and the time after the first time period to the expected arrival time is the first time period, that is, the range extender is no longer started in the first time period to reduce the power generation of the range extender. Then, the intersection of the working time period and the first time period is deleted in the working time period.

[0128] To further improve the NVH performance, in one embodiment, first, in response to the fourth electrical quantity being greater than the first electrical quantity, it is determined to use the first rule to reduce the power generation of the range extender.

[0129] Therefore, in the vehicle speed distribution information, the first vehicle speed that is greater than the first threshold and less than the second threshold is selected as the third vehicle speed, wherein the second threshold is greater than the first threshold.

[0130] Then, based on the target power corresponding to the third vehicle speed, a power set corresponding to the difference between the fourth power and the first power is determined. The power supply of the range extender corresponding to the power set is equal to the difference between the fourth power and the first power.

[0131] The power set is composed of multiple sets of target power and time. For example, each set of target power and time can be expressed as (Pg, T)

[0132] Next, the time period consisting of the time corresponding to the power set is determined as the first time period, and the first time period is deleted from the aforementioned multiple working time periods, that is, the intersection between the working time period and the first time period is deleted to obtain the optimized working time period.

[0133] To further improve NVH performance and avoid battery feeding due to insufficient battery power during driving, in one embodiment, in response to the fourth power level being less than the first power level, it is determined to use the second rule to increase the power generation of the range extender.

[0134] Therefore, in the vehicle speed distribution information, the first vehicle speed that is greater than the second threshold value may be selected as the fourth vehicle speed.

[0135] According to the corresponding relationship between the vehicle speed and the third power, or the power distribution information, the target power corresponding to the fourth vehicle speed is determined as the target power to be adjusted.

[0136] Next, the value of the target power to be adjusted is increased so that the power supply corresponding to the adjusted target power and the target power that does not need to be adjusted is equal to the difference between the fourth power and the first power. Specifically, the preset target factor can be fine-tuned multiple times until the power supply corresponding to the adjusted target power is equal to the difference between the fourth power and the first power.

[0137] The target power indication that does not need to be adjusted is the target power other than the target power to be adjusted.

[0138] Furthermore, the above-mentioned optimization rules may also include a third rule, which may indicate that the first time period is determined to delete the first time period in the working time period, and the target power to be adjusted is determined to reduce the value of the target power to be adjusted, thereby reducing the fourth power.

[0139] The third rule can be selected in combination with specific road conditions and driving modes.

[0140] The following combination Figure 5 According to steps 201 to 204, the control method of the range extender is further illustrated by examples:

[0141] After receiving the driving instruction, based on the driving section, departure time and other information in the driving instruction, the cloud is requested to obtain: traffic light information, road congestion information, and mileage (i.e., the length of the driving section) of the specified section during the estimated driving time. The driving section can be obtained by combining the departure time, departure place, and destination with map planning, or it can be directly determined according to the user's instructions.

[0142] At the same time, after receiving the driving command, the following information can be queried from the vehicle: historical energy consumption information, such as average energy consumption per 100 kilometers; driving mode, such as economy mode and power mode, which can be determined based on user habits and whether the designated section is located on a highway and other driving information; ambient temperature, when the ambient temperature is low or high, the air conditioning equipment may be turned on; and the battery SOC.

[0143] Next, the distribution information of the vehicle speed is predicted based on the traffic light information and the congestion information, that is, the correspondence between the first vehicle speed and time when the vehicle travels on the designated road section after the departure time.

[0144] The power required for the entire journey is predicted based on congestion information, mileage, historical energy consumption information, driving mode, and ambient temperature, that is, the second power A required for the vehicle to travel the entire specified section. At the same time, the SOC is queried, and the SOC is subtracted from the preset SOC threshold to obtain the remaining available power of the battery, the third power B. The SOC of the battery obtained from this query can be understood as the real-time SOC of the battery, and the preset SOC threshold can correspond to the threshold at which the battery does not supply power.

[0145] It is determined whether A is greater than or equal to B. If so, it is determined that the battery power meets the driving demand corresponding to the driving instruction, and pure electric driving is determined; the range extender is not allowed to be turned on during the entire journey.

[0146] If not, the first power C of the range extender is determined as the power generation target of the range extender traveling on the designated road section.

[0147] Furthermore, the working time period of the range extender is determined according to the vehicle speed distribution information, that is, the time period in which the first vehicle speed in the vehicle speed distribution information is greater than the first threshold is determined as the working time, and the driving time includes the working time. The working time includes at least one working time period. The working time period of the range extender driving on the specified road section can continue to refer to Figure 3 Example shown.

[0148] Next, pre-calibrated power data is obtained, which includes a corresponding relationship between the driving power (ie, the first power) and the first vehicle speed, and also includes a corresponding relationship between the NVH power (ie, the second power) and the first vehicle speed.

[0149] The first vehicle speed corresponds to the first power and the second power at the same time. The minimum value of the first power and the second power is determined as the third power corresponding to each first vehicle speed, and the third power can be used as the power generation power of the range extender when the vehicle travels to the corresponding first vehicle speed.

[0150] In this way, the third power corresponding to the range extender in the working time period can be determined as the target power according to the correspondence between the third power and the first vehicle speed, the correspondence between the first vehicle speed and time in the vehicle speed distribution information, and the working time period of the range extender. The target power and the time corresponding to it can be used as the power distribution information of the working time. Then the target power in the power distribution information corresponds to the time and corresponds to the first vehicle speed.

[0151] According to the first power distribution information, the total power generation can be calculated by integrating the power over time: the fourth power D.

[0152] Finally, determine whether D is greater than or equal to C; if not, increase the value of the target rate corresponding to the partial working time period, that is, use the preset target factor greater than 1, add it to the target power to be adjusted, and obtain the adjusted power distribution information. After multiple adjustments, the power generation corresponding to the adjusted target power and the target power that does not need to be adjusted is equal to C. The adjusted target power and the target power that does not need to be adjusted together constitute all the target powers in the working state of the range extender.

[0153] If D is greater than or equal to C, then based on the power distribution information, the first time during the driving process when D=C is calculated as the target time, and the target time is determined to be the last stop point.

[0154] Then, the time period after the target time is deleted from the working time period. In this way, the working time period and power generation of the range extender during the entire journey on the specified road section can be obtained.

[0155] It should be understood that although Figure 2 , Figure 4The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2 , Figure 4 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
