[0029] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present application. On the contrary, they are only examples of the devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0030] The block diagrams shown in the accompanying drawings are only functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0031] The flowcharts shown in the accompanying drawings are only illustrative and do not necessarily include all contents and operations / steps, nor do they necessarily need to be executed in the described order. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined. Therefore, the actual execution order may change according to the actual situation.

[0032] The "plurality" mentioned in this application refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0033] Existing range-extended electric vehicles generally start burning gasoline only when the electric energy is insufficient to obtain the energy to drive the vehicle. When a range-extended electric vehicle travels on a slope section and consumes electricity, if the battery power of the vehicle is insufficient at this time, it will cause the remaining electric energy of the vehicle to drop rapidly, and the power performance of the vehicle will decay. It is necessary to control the range extender to generate electricity at high power, and the noise during the power generation process is obvious, resulting in a poor driving experience of the vehicle.

[0034] For this reason, one aspect of this application provides a control method for a range extender in a slope driving condition. For details, please refer to Figure 1 , Figure 1 is a schematic flowchart of a control method for a range extender in a slope driving condition shown in an exemplary embodiment of this application. This control method at least includes S110 to S140, which are introduced in detail as follows:

[0035] S110: Receive slope driving condition information; where the slope driving condition information includes the slope section corresponding to the slope starting position to the slope ending position, the vertical height between the slope starting position and the slope ending position, the average driving speed of the vehicle on the slope section, the driving section from the current vehicle position to the slope starting position, and the average driving speed at the current moment.

[0036] The uphill road condition information is information included in the navigation information. The execution end sends a navigation request to a third-party platform. The third-party platform obtains the real-time position of the vehicle end, and based on the navigation destination information in the navigation request, collects relevant road condition information, and generates corresponding navigation information through analysis and processing, and then sends it to the execution end. Among them, the execution end can be a controller placed inside the vehicle end or a controller placed outside the vehicle end, and this embodiment does not limit it.

[0037] The uphill section can be the road driving length analyzed by the third-party platform based on the real-time collected road condition information. The average uphill road speed can be the average speed calculated by the third-party platform using the vehicle speeds of other vehicles driving on the uphill section as a reference basis, combined with relevant road speed limit information and relevant operating parameters of the vehicle end.

[0038] The driving section is the road length traveled by the vehicle end calculated by the third-party platform through a simple mathematical algorithm based on the obtained real-time position of the vehicle end and the uphill starting position.

[0039] The vertical height between the uphill starting position and the uphill ending position can be accurately calculated by technologies such as satellite remote sensing to obtain the altitude difference between the two positions, so as to determine the vertical height between them.

[0040] S120: Calculate the first detected battery power percentage corresponding to the uphill section according to the uphill section, vertical height, and average uphill road speed.

[0041] The first detected battery power percentage is a reference value calculated based on real-time data, and this value is used as a basic reference value to determine whether to control the range extender to generate electricity before the vehicle runs to the uphill starting position.

[0042] Exemplarily, the first detected battery power percentage is calculated according to the following calculation formula:

[0043]

[0044] Among them, SOC 1 represents the first detected battery power percentage; E represents the total battery power; SOC min represents the minimum battery power percentage corresponding to the uphill section; G represents the gravitational constant, 9.8N / kg; N represents the number of passengers in the vehicle; η m represents the preset average efficiency of the drive motor; h represents the vertical height between the uphill starting position and the uphill ending position.

[0045] S130: Calculate the theoretical battery power percentage corresponding to the vehicle reaching the starting position of the slope based on the driving section and the average vehicle speed at the current moment, and determine the target battery power percentage according to the theoretical battery power percentage and the critical battery power percentage when the range extender starts.

[0046] The driving section and the average vehicle speed at the current moment are the main original parameters for calculating the theoretical battery power percentage, and other parameters may also be involved.

[0047] An exemplary description of the calculation process of the theoretical battery power percentage is as follows: The theoretical battery power percentage is calculated according to the following calculation formula:

[0048]

[0049] where SOC 理论 represents the theoretical battery power percentage; E represents the total battery power; SOC act represents the battery power percentage at the current moment; e 2 represents the average power consumption of the current driving section, which can be determined according to the average vehicle speed at the current moment; S 2 represents the driving section.

[0050] The process of determining the target battery power percentage according to the theoretical battery power percentage and the critical battery power percentage when the range extender starts can be to perform a maximum or minimum value operation between the theoretical battery power percentage and the critical battery power percentage, that is, take the maximum or minimum value between the two as the target battery power percentage; or take the average value or variance value of the two as the target battery power percentage.

[0051] Exemplarily, SOC 2 = max(SOC 理论 , SOC str ), that is, take the maximum value between the theoretical battery power percentage and the critical battery power percentage as the target battery power percentage.

[0052] S140: If it is detected that the target battery power percentage is less than or equal to the first detected battery power percentage, then before the vehicle reaches the starting position of the slope, control the range extender to perform a power generation operation to obtain the supplementary electric energy required by the vehicle in the slope section.

[0053] If the target battery power percentage is less than or equal to the first detected battery power percentage, it indicates that the remaining battery power of the current vehicle is not enough to support the vehicle to pass through the slope section in pure electric mode, and the range extender of the vehicle needs to perform a high-power power generation operation in the slope section.

[0054] In some embodiments, during the comparison process between the target battery power percentage and the first detected battery power percentage, a preset error battery power percentage needs to be introduced to reduce the accidental error of detection using the first detected battery power percentage to a certain extent, so as to more accurately determine whether to control the range extender to generate electricity before the vehicle reaches the starting position of the slope climbing, so as to obtain the supplementary electric energy required by the vehicle during the slope climbing section.

[0055] Exemplarily, SOC 2 represents the target battery power percentage, SOC 1 represents the first detected battery power percentage, SOC deta represents the preset error battery power percentage. If it is detected that SOC 2 ≤SOC 1 +SOC deta , it indicates that the existing remaining electric energy of the vehicle cannot meet the pure electric driving requirements of the vehicle on the slope climbing section, and it is necessary to control the range extender to generate electricity before the vehicle runs to the starting position of the slope climbing to obtain the supplementary electric energy required by the vehicle during the slope climbing section. If it is detected that SOC 2 >SOC 1 +SOC deta , it indicates that the existing remaining electric energy at the vehicle end is sufficient to meet the pure electric driving requirements of the vehicle on the slope climbing section, and there is no need to start the range extender in advance for additional power generation.

[0056] In this embodiment, based on the relevant parameters in the received slope climbing road condition information, the first detected battery power percentage corresponding to the slope climbing section and the target battery power percentage corresponding to the vehicle running to the starting position of the slope climbing are calculated; the two battery power percentages are compared to quickly determine whether it is necessary to control the range extender to generate electricity before the vehicle runs to the starting position of the slope climbing to obtain the supplementary electric energy required by the vehicle during the slope climbing section, so as to avoid the range extender being forced to generate electricity at high power on the slope climbing section where the slope resistance needs to be overcome, thereby avoiding obvious noise and improving the driving experience of the vehicle.

[0057] In an exemplary embodiment of the present application, it is described how to calculate the theoretical battery power percentage corresponding to the vehicle running to the starting position of the slope climbing. For details, please refer to Figure 2 , Figure 2 is a schematic flowchart of another control method of the range extender for a slope climbing road condition shown based on the exemplary embodiment shown in Figure 1 . This control method further includes S210 to S220 in S130 as shown in Figure 1 . The details are introduced as follows:

[0058] S210: Obtain the total battery power and the battery power percentage at the current moment.

[0059] The total battery capacity is the maximum amount of electricity that the battery can store, i.e., the upper limit of the stored electricity, and the general unit is kwh.

[0060] The battery charge percentage at the current moment represents the remaining battery charge of the vehicle at the current moment. For example, 50%, which means that the current remaining battery charge is 50% of the total battery capacity.

[0061] S220: Calculate the theoretical battery charge percentage corresponding to the vehicle when it travels to the starting position of the slope according to the total battery capacity, the battery charge percentage at the current moment, the driving section, and the average vehicle speed at the current moment.

[0062] Exemplarily, the theoretical battery charge percentage is calculated according to the following formula:

[0063]

[0064] Among them, SOC 理论 represents the theoretical battery charge percentage; E represents the total battery capacity; SOC act represents the battery charge percentage at the current moment; e 2 represents the average power consumption of the current driving section, which can be determined according to the average vehicle speed at the current moment; S 2 represents the driving section.

[0065] This embodiment provides a method for calculating the theoretical battery charge percentage. It clarifies the original parameters required for calculating the theoretical battery charge percentage, including the total battery capacity, the battery charge percentage at the current moment, the driving section, and the average vehicle speed at the current moment, and calculates the theoretical battery charge percentage according to the original parameters.

[0066] In an exemplary embodiment of the present application, how to further calculate the theoretical battery charge percentage corresponding to the vehicle when it travels to the starting position of the slope is introduced in detail. For details, please refer to Figure 3 , Figure 3 is based on Figure 2 The flowchart of another control method of the range extender for a climbing road condition shown in the exemplary embodiment. This control method further includes S310 to S320 in S220 as shown in Figure 2 as follows:

[0067] S310: Determine the preset average power consumption of the vehicle at the current moment according to the average vehicle speed at the current moment.

[0068] Exemplarily, Table 1 is a correspondence table between the preset average vehicle speed and the preset average power consumption. Match the average vehicle speed at the current moment with the preset average vehicle speed in Table 1, and use the preset average power consumption corresponding to the successfully matched preset average vehicle speed as the target preset average power consumption, that is, the preset average power consumption of the vehicle at the current moment.

[0069] For example, the average vehicle speed at the current moment is 50, which successfully matches the preset average vehicle speed of 50 in Table 1. The preset average power consumption corresponding to the preset average vehicle speed of 50 is 10, so it is used as the preset average power consumption of the vehicle at the current moment.

[0070]

[0071]

[0072] Table 1

[0073] S320: Calculate the theoretical battery power percentage corresponding to the vehicle when it travels to the starting position of the slope according to the preset average power consumption, the total battery power, the current battery power percentage, and the driving section.

[0074] Exemplarily, the theoretical battery power percentage is calculated according to the following formula:

[0075]

[0076] Among them, SOC 理论 represents the theoretical battery power percentage; E represents the total battery power; SOC act represents the current battery power percentage; e 2 represents the average power consumption of the current driving section; S 2 represents the driving section.

[0077] This embodiment further illustrates that in the process of the theoretical battery power percentage, the preset average power consumption of the vehicle at the current moment is determined according to the original parameter - the average vehicle speed at the current moment. Thus, according to the preset average power consumption, the total battery power, the current battery power percentage, and the driving section, only simple mathematical formulas are involved in the whole calculation process, so as to quickly calculate the theoretical battery power percentage.

[0078] In an exemplary embodiment of the present application, how to calculate the first detected battery power percentage corresponding to the slope section is introduced in detail. For details, please refer to Figure 4 , Figure 4 is a schematic flow chart of another control method of the range extender for a slope road condition shown based on Figure 1 the exemplary embodiment shown. This control method further includes S410 to S440 in S120 shown in Figure 1 as follows:

[0079] S410: Obtain the total weight of the vehicle and the load, the total battery power, and the critical battery power percentage when the range extender starts.

[0080] The weight of the vehicle is the weight of the vehicle itself, and the weight of the load is the weight of the on-vehicle items and people, etc. The total weight in this embodiment is the total weight during the operation of the vehicle.

[0081] The critical battery power percentage (SOC str ) is the preset battery power percentage corresponding to the starting moment of the range extender. That is, when the battery power percentage of the vehicle battery drops to this critical battery power percentage, the range extender will be immediately controlled to perform a power generation operation.

[0082] S420: Calculate the minimum battery power percentage corresponding to the climbing section according to the total battery power, the critical battery power percentage, the average vehicle speed on the climbing section and the climbing road conditions.

[0083] The minimum battery power percentage is calculated according to the following calculation formula:

[0084]

[0085] Among them, SOC min represents the minimum battery power percentage corresponding to the climbing section; E represents the total battery power; SOC str represents the critical battery power percentage when the range extender starts; e 1 represents the average power consumption on the climbing section, which can be determined according to the average vehicle speed on the climbing road conditions; S 1 represents the climbing section.

[0086] S430: Calculate the supplementary electric energy required by the vehicle in the climbing section according to the total weight, the vertical height and the preset average efficiency of the drive motor.

[0087] Exemplarily, the supplementary electric energy is calculated according to the following formula:

[0088]

[0089] Among them, J represents the supplementary electric energy; G represents the gravitational constant, 9.8 N / kg; N represents the number of vehicle passengers; η m represents the preset average efficiency of the drive motor; h represents the vertical height between the starting position and the ending position of the climb.

[0090] S440: Calculate the first detected battery power percentage corresponding to the climbing section according to the supplementary electric energy, the total battery power and the minimum battery power percentage.

[0091] Exemplarily, the first detected battery power percentage is calculated according to the following formula:

[0092]

[0093] Among them, SOC 1Indicates the first detected battery power percentage; J indicates supplementary power; E indicates the total battery power; SOC min Indicates the minimum battery power percentage corresponding to the uphill section.

[0094] This embodiment provides a method for calculating the first detected battery power percentage. By using relevant parameters, the minimum battery power percentage and supplementary power are calculated respectively, and then the first detected battery power percentage can be quickly obtained through a simple calculation formula.

[0095] In an exemplary embodiment of the present application, how to determine the starting moment of the range extender is introduced in detail. For details, please refer to Figure 5 , Figure 5 is based on Figures 1 to 4 It is a schematic flow chart of another control method of the range extender for an uphill road condition shown in any of the exemplary embodiments shown. This control method further includes S510 to S540 in S140, which are introduced in detail as follows:

[0096] S510: Obtain the preset error battery power percentage, and determine the preset average power consumption of the vehicle at the current moment according to the average vehicle speed at the current moment.

[0097] S520: Calculate the change duration required for the battery power percentage of the vehicle to drop to the critical battery power percentage at the current moment according to the preset error battery power percentage, preset average power consumption, battery power percentage at the current moment, average vehicle speed at the current moment, and critical battery power percentage.

[0098] Exemplarily, the change duration is calculated according to the following formula:

[0099]

[0100] where, E represents the total battery power; SOC act represents the battery power percentage at the current moment; SOC str represents the critical battery power percentage when the range extender starts; SOC deta represents the preset error battery power percentage; e 2 represents the average power consumption of the current driving section, which can be determined according to the average vehicle speed at the current moment; v 2 represents the average vehicle speed at the current moment.

[0101] S530: Calculate the power generation duration of the range extender according to the supplementary power and the preset power generation power.

[0102] Exemplarily, the power generation duration is calculated according to the following formula: where, J represents the supplementary power; P k represents the preset power generation power of the range extender.

[0103] S540: Determine the starting moment for controlling the range extender to generate electricity based on the magnitude relationship between the power generation duration and the change duration, and control the range extender to generate electricity at the starting moment.

[0104] Compare t 发电 with t 变化 to determine the starting moment of the range extender according to their magnitude relationship.

[0105] This embodiment provides a method for determining the starting moment of range extender power generation. By determining the starting moment of range extender power generation based on the magnitude relationship between the power generation duration and the change duration, controlling the range extender to generate electricity at the starting moment, the supplementary electric energy required by the vehicle on the climbing section can be obtained, so as to avoid the range extender being forced to generate electricity at high power on the climbing section where the slope resistance needs to be overcome, thereby avoiding obvious noise and improving the driving experience of the vehicle.

[0106] In an exemplary embodiment of the present application, how to determine the power generation moment for controlling the range extender to generate electricity based on the magnitude relationship between the power generation duration and the change duration is introduced in detail. For details, please refer to Figure 6 , Figure 6 is based on Figure 5 The flowchart of another control method for the range extender in a climbing road condition shown in the exemplary embodiment. This control method further includes S610 to S630 in S540, which are introduced in detail as follows:

[0107] S610: If the magnitude relationship indicates that the power generation duration is less than or equal to the change duration, calculate the driving duration for the vehicle to travel from the current vehicle position to the starting position of the climb according to the driving section and the average vehicle speed at the current moment.

[0108] Exemplarily, according to a simple calculation formula: where S 2 represents the driving section, and V 2 represents the average vehicle speed at the current moment.

[0109] S620: Calculate the non-power generation duration of the range extender according to the driving duration and the power generation duration.

[0110] The non-power generation duration in this embodiment refers to the duration during which the range extender does not generate electricity before the vehicle travels to the starting position of the climb. Among them, the non-power generation duration = driving duration - power generation duration, that is

[0111] S630: Calculate the starting moment for the range extender to generate electricity according to the current moment and the non-power generation duration.

[0112] Exemplarily, the current time is 10:00 and the non - power - generation duration is 10 minutes. Then, during the period from 10:00 to 10:10, the range extender does not perform power - generation operation, and at 10:10, the range extender performs power - generation operation. That is, the starting time of the range extender's power - generation operation is 10:10.

[0113] This embodiment provides a determination method for calculating the starting time of the range extender's power - generation operation. That is, when it is detected that the target battery power percentage is less than or equal to the first detected battery power percentage, the non - power - generation duration is calculated through the driving duration and the power - generation duration, and then the starting time of the range extender's power - generation operation is calculated based on the current time and the non - power - generation duration. The whole process only involves simple calculation formulas, making the calculation process more convenient and fast.

[0114] In an exemplary embodiment of the present application, how to determine the power - generation time for controlling the range extender to perform power - generation operation based on the magnitude relationship between the power - generation duration and the change duration is introduced in detail. For details, please refer to Figure 7 , Figure 7 is based on Figure 5 which is a schematic flow chart of another control method for the range extender in a climbing road condition shown in the exemplary embodiment. This control method further includes S710 in S520, which is introduced in detail as follows:

[0115] S710: If the magnitude relationship indicates that the power - generation duration is greater than the change duration, determine the current time as the power - generation time for controlling the range extender to perform power - generation operation.

[0116] Exemplarily, the range extender performs three different power - generation operation stages: The first power - generation operation stage: from the current time to the T 1 moment stage, the range extender generates power at the maximum preset power - generation power; where the T 1 moment is the moment corresponding to when the battery power percentage of the vehicle drops from the current - time battery power percentage to the critical battery power percentage, that is, the moment corresponding to after the current time passes through the change duration.

[0117] Among them, the range extender generates power according to the preset power - generation power. The preset power - generation power can be obtained through the range extender efficiency calibration experiment. For example, the high - efficiency power - generation power range of the range extender is equally divided into 10 points: [P 1 , P 2 , P 2 , P 4 ......P 10 , and the corresponding efficiency is [η 1 , η 2 , η 3 , η 4 ......η 10Based on the driving section and the average vehicle speed at the current moment, a preset power generation power for calculating the power generation duration can be determined. Exemplarily, dividing the supplementary electric energy by the preset power generation power, the obtained quotient value is the power generation duration of the range extender, that is where J represents the supplementary electric energy, and P k represents the preset power generation power, and k represents a value from 1 to 10.

[0118] If it means that the generated electric energy obtained by generating electricity according to the preset power generation power cannot meet the electric energy demand for the subsequent vehicle to drive purely electrically on the uphill section. Then, the preset power generation power with the highest power generation (P max ) is selected as the power generation power of the range extender in this stage.

[0119] Second power generation operation stage: From the moment T 1 to the corresponding moment when the vehicle travels to the starting position of the uphill section, the power generation power of the range extender in the second power generation operation stage is calculated according to the following calculation formula:

[0120] where a, b, and c represent the vehicle sliding resistance coefficients, which are preset constants determined by vehicle sliding tests; η m represents the average efficiency of the drive motor; η g represents the average efficiency of the range extender generator, which is a preset parameter and can be determined according to the actual test results of the vehicle under WLTC (World Light Vehicle Test Cycle); V represents the current vehicle speed, in km / h.

[0121] Third power generation operation stage: When the vehicle is on the uphill section, the range extender generates electricity with a power of P 1 to avoid the range extender generating electricity with high power on the uphill section, so as to reduce the noise generated by the range extender during power generation on the uphill section.

[0122] This embodiment provides another determination method for the starting moment of the range extender to perform power generation operation, that is, when it is detected that the target battery power percentage is greater than the first detected battery power percentage, the range extender is immediately started so that the range extender performs power generation operation at the current moment to supplement the battery energy, avoiding the range extender generating electricity with high power on the uphill section, so as to reduce the noise generated by the range extender during power generation on the uphill section.

[0123] In another exemplary embodiment of the present application, the application scenarios of the above multiple control methods are exemplarily described. For details, please refer to Figure 8 , Figure 8It is a schematic diagram of the application scenario of the control method of this application. Among them, it includes a vehicle 100, a controller 200, and a third-party platform 300, which can be connected by wireless communication. This application does not limit the connection method between them.

[0124] The vehicle 100 can send its own position information and relevant working condition information to the third-party platform 300. The third-party platform 300 generates the climbing road condition information sent to the controller 200 based on the relevant information received from the vehicle 100, as well as the driving data of other vehicles and real-time road information collected, etc., so that the controller 200 can execute the control method of the range extender for the climbing road condition shown in each of the above exemplary embodiments. The following is an exemplary description:

[0125] The controller 200 receives the climbing road condition information; among them, the climbing road condition information includes the climbing section corresponding to the climbing start position to the climbing end position, the vertical height between the climbing start position and the climbing end position, the average climbing road condition speed of the vehicle 100 in the climbing section, the driving section from the current vehicle position to the climbing start position, and the average speed at the current moment; the controller 200 calculates the first detected battery power percentage corresponding to the climbing section according to the climbing section, the vertical height, and the average climbing road condition speed; the controller 200 calculates the theoretical battery power percentage corresponding to the vehicle 100 traveling to the climbing start position according to the driving section and the average speed at the current moment, and determines the target battery power percentage according to the theoretical battery power percentage and the critical battery power percentage when the range extender starts; if the controller 200 detects that the target battery power percentage is less than or equal to the first detected battery power percentage, it controls the range extender to perform a power generation operation before the vehicle travels to the climbing start position, so as to obtain the supplementary electric energy required by the vehicle 100 in the climbing section.

[0126] As Figure 9 shown, Figure 9 It is a schematic diagram of the change in the battery power percentage of this application vehicle and existing vehicles during operation. This application calculates relevant parameters and makes a simple comparison of the sizes according to the calculated relevant parameters to determine that before the vehicle travels to the climbing start position, the range extender is controlled to perform a power generation operation to obtain the supplementary electric energy required by the vehicle in the climbing section, so that the vehicle can travel in pure electric mode or the range extender generates power with a small power during the climbing section, avoiding the range extender being forced to generate power with a large power during the climbing section and generating obvious noise, so as to improve the driving experience of the vehicle.

[0127] Among them, the controller 200 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. Multiple servers can form a blockchain, and the server is a node on the blockchain. The controller 200 can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.
