The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0034] The extended-range electric vehicle generally uses electric energy to run, and burns gasoline to obtain driving energy when the electric energy is insufficient. During the driving process on the congested road section, the range extender may be forced to start, so that the range extender performs the power generation operation with small power, low efficiency and obvious noise, resulting in poor experience of driving the vehicle.

[0035] Therefore, an aspect of the present application provides a control method of a range extender in a traffic jam road section. For details, please refer to Figure 1 , Figure 1 FIG. 1 is a flowchart of a control method of a range extender in a traffic jam road section according to an example embodiment of the present application. The control method at least includes S110 to S140, which are described in detail as follows:

[0036] S110: receiving traffic jam road section information; wherein the traffic jam road section information includes a traffic jam road section corresponding to a traffic jam starting position to a traffic jam ending position, a traffic jam road section average speed of a vehicle in the traffic jam road section, and a driving road section and a current time average speed of the vehicle from a current time position to the traffic jam starting position.

[0037] The traffic jam road section information is information contained in the navigation information. The execution end sends a navigation request to the third party platform, the third party platform acquires the real-time position of the vehicle end, and according to the navigation destination information in the navigation request, collects the relevant road condition information, and generates the corresponding navigation information after analysis and processing, and sends it to the execution end. The execution end can be a controller placed in the vehicle end, or a controller placed outside the vehicle end, which is not limited in the embodiment.

[0038] The traffic jam road section can be the road length analyzed by the third party platform according to the real-time collected road condition information. The traffic jam road section average speed can be the average speed calculated by the third party platform based on the speed of other vehicles running on the traffic jam road section as a reference, combined with the relevant running parameters of the vehicle end.

[0039] The driving road section is the road length calculated by the third party platform according to the real-time position of the vehicle end and the traffic jam starting position by simple mathematical algorithm.

[0040] S120: calculating a first detected battery power percentage corresponding to the traffic jam road section according to the traffic jam road section and the traffic jam road section average speed.

[0041] The first detected battery power percentage is a reference value calculated according to real-time data, which is used as a basic reference value to determine whether to control the range extender to perform power generation operation before the vehicle runs to the traffic jam starting position.

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

[0043]

[0044] wherein, SOC1 represents the first detected battery percentage; E represents the total battery capacity; SOC str represents the preset battery percentage for starting the range extender; e1 represents the average power consumption of the traffic jam section, which can be determined according to the average speed of the traffic jam; and S1 represents the traffic jam section.

[0045] S130: calculating the target battery percentage corresponding to the traffic jam starting position according to the driving section and the average speed at the current time.

[0046] The driving section and the average speed at the current time are the main original parameters in the calculation process of the target battery percentage. In some embodiments, the average speed at the current time can be used to determine the average power consumption of the current driving section, and the average power consumption and the driving section are used as the basic calculation parameters to calculate the target battery percentage.

[0047] Exemplarily, the target battery percentage is calculated according to the following calculation formula:

[0048]

[0049] wherein, SOC2 represents the target battery percentage; E represents the total battery capacity; SOC act represents the battery percentage at the current time; e2 represents the average power consumption of the current driving section, which can be determined according to the average speed at the current time; and S2 represents the driving section.

[0050] S140: if the detected target battery percentage is less than the first detected battery percentage, the range extender is controlled to generate power before the vehicle runs to the traffic jam starting position, so as to obtain the supplementary power required by the vehicle in the traffic jam section.

[0051] Exemplarily, SOC2 represents the target battery percentage, SOC1 represents the first detected battery percentage, and SOC str represents the preset battery percentage for starting the range extender. If it is detected that SOC2≤SOC str or SOC strIf SOC2 < SOC1, meaning the target battery percentage is less than the first detected battery percentage, it indicates that the vehicle's existing remaining electrical energy is insufficient for pure electric driving in congested traffic. The range extender needs to be activated to generate electricity before the vehicle reaches the start of the traffic jam to provide the necessary supplementary power. If SOC2 ≥ SOC1, it indicates that the vehicle's existing remaining electrical energy is sufficient to meet the pure electric driving requirements in congested traffic, and the range extender does not need to be activated in advance.

[0052] This embodiment calculates the first detected battery percentage corresponding to the congested section and the target battery percentage corresponding to the starting position of the congestion by receiving traffic congestion information including multiple parameters. The two battery percentages are compared to determine whether the range extender needs to generate electricity before the vehicle reaches the starting position of the congestion to obtain the supplemental power required by the vehicle in the congested section. This avoids the range extender being forced to start in slow-moving congested sections, thus avoiding the range extender performing low-power, inefficient, and noisy power generation operations in low-speed sections, thereby improving the driving experience.

[0053] In an exemplary embodiment of this application, it is described how to control the range extender to perform power generation before the vehicle reaches the starting position of the traffic jam, so as to obtain the supplementary electrical energy required by the vehicle in the traffic jam section. Please refer to the following for details. Figure 2 , Figure 2 Based on Figure 1 The exemplary embodiment shown illustrates a flowchart of another control method for a range extender in congested traffic conditions. This control method, in situations such as... Figure 1 S140 shown further includes S210 to S220, which are described in detail below:

[0054] S210: Based on the total battery charge, first detect the battery charge percentage and the target battery charge percentage, and calculate the supplementary power required by the vehicle in congested road sections.

[0055] For example, the supplementary electrical energy is calculated according to the following formula:

[0056] J = E × |SOC2 - SOC1|;

[0057] Where E represents the total battery capacity, SOC1 represents the percentage of the first detected battery capacity, and SOC2 represents the percentage of the target battery capacity.

[0058] S220: Based on the supplementary power and the preset power generation capacity of the range extender, calculate the power generation duration of the range extender and control the range extender to perform the power generation operation for the specified duration.

[0059] The preset power generation power is a preset parameter, which can be obtained according to the efficiency calibration experiment of the range extender, for example, the interval of the high-efficiency power generation power of the range extender is equally divided into 10 points: [P1, P2, P2, P4... P 10 ], and the corresponding efficiency is [η1, η2, η3, η4... η 10 ]. According to the driving section and the current average speed, the preset power generation power for calculating the power generation duration can be determined, so that the power generation duration of the range extender can be accurately calculated. For example, the quotient obtained by dividing the supplementary electric energy by the preset power generation power is the power generation duration of the range extender, that is, , wherein J represents the supplementary electric energy, and P k represents the preset power generation power.

[0060] The embodiment provides a way of calculating the power generation duration of the range extender. According to the total battery capacity, the first detected battery capacity percentage and the target battery capacity percentage, the supplementary electric energy required by the vehicle in the traffic jam section is calculated. According to the supplementary electric energy and the preset power generation power of the range extender, the power generation duration of the range extender is calculated. The power generation duration can be accurately calculated by only simple mathematical formula calculation in the embodiment, and the whole calculation process is convenient and fast, so that the power generation operation of the range extender for the power generation duration can be accurately controlled.

[0061] In an example embodiment of the present application, how to control the range extender to perform the power generation operation for the power generation duration is introduced in detail, please refer to Figure 3 , Figure 3 is another flowchart of a control method of a range extender in a traffic jam road condition, which is shown in the example embodiment shown in Figure 2 . The control method further includes S310 to S330 in S220 shown in Figure 2 , which are introduced in detail as follows:

[0062] S310: According to the driving section and the current average speed, the driving duration of the vehicle driving to the traffic jam starting position is calculated.

[0063] S320: According to the driving duration and the power generation duration, the non-power generation duration of the range extender is calculated.

[0064] S330: According to the current time and the non-power generation duration, the starting time of the power generation operation of the range extender is calculated, and the range extender is controlled to perform the power generation operation at the starting time.

[0065] The related calculation process of the embodiment is exemplarily described as follows: the driving duration of the vehicle driving to the traffic jam starting position is calculated according to the following formula: , wherein S2 represents the driving section, and V2 represents the current average speed. The power generation duration of the range extender is calculated according to the following formula: Where J represents supplemental electrical energy, P k This indicates the preset power generation capacity.

[0066] The duration of no power generation is calculated using the following formula:

[0067]

[0068] This embodiment provides a method for calculating the duration during which a range extender is not generating electricity. By using the current time and the duration of non-generating electricity, it is possible to determine when to activate the range extender to perform power generation. Because the power generation and non-generating electricity durations are already calculated, the activation time of the range extender can be flexibly scheduled before the vehicle reaches the starting point of the traffic jam.

[0069] In an exemplary embodiment of this application, a detailed description is provided of how to calculate the supplemental electrical energy required by a vehicle in a congested traffic area. Please refer to [link to relevant documentation] for details. Figure 4 , Figure 4 Based on Figure 2 The exemplary embodiment shown illustrates a flowchart of another control method for a range extender in congested traffic conditions. This control method, in situations such as... Figure 2 The S210 shown further includes S410 to S420, which are described in detail below:

[0070] S410: Calculate the difference between the first detected battery percentage and the target battery percentage.

[0071] S420: Multiply the difference with the total battery capacity and use the product as the supplementary power needed by the vehicle in congested areas.

[0072] For example, the difference = SOC1 - SOC2, and the supplementary electrical energy is calculated according to the following formula:

[0073] J = E × (SOC1 - SOC2);

[0074] Where E represents the total battery capacity, SOC1 represents the percentage of the first detected battery capacity, and SOC2 represents the percentage of the target battery capacity.

[0075] This embodiment provides a method for calculating supplemental power. By multiplying the difference between the first detected battery power percentage and the target battery power percentage with the total battery power, the supplemental power required by the vehicle in congested traffic can be calculated quickly.

[0076] In an exemplary embodiment of this application, the calculation of the power generation duration of the range extender is described in detail. Please refer to [link to relevant documentation] for details. Figure 5 , Figure 5 Based on Figure 2Another flowchart of the control method of the range extender in the traffic jam is shown in the exemplary embodiment. The control method is shown in S220, which further includes S510-S530, as follows: Figure 2 S220 further includes S510-S530, as follows:

[0077] S510: According to the driving section and the current average speed, the driving time of the vehicle driving to the start position of the traffic jam is calculated.

[0078] Referring to the calculation method of the driving time in 310 above: Wherein, S2 represents the driving section, and V2 represents the current average speed.

[0079] S520: According to the supplementary electric energy and the driving time, the target power generation power is calculated, and it is detected whether the target power generation power is greater than each preset power generation power.

[0080] The target power generation power is calculated according to the following formula: P 目标 = J x t 行驶 ; wherein, P 目标 represents the target power generation power, J represents the supplementary electric energy, and t 行驶 represents the driving time.

[0081] Exemplarily, the preset power generation power includes P1, P2, P2, P4, …, P 10 Each preset power generation power is compared with the target power generation power.

[0082] S530: If it is greater than, according to the supplementary electric energy and the preset power generation power with the highest power generation power in the plurality of preset power generation powers, the power generation time of the range extender is calculated.

[0083] If the target power generation power is greater than each preset power generation power, it represents that the power generation energy obtained by power generation according to the preset power generation power cannot meet the electric energy demand of the subsequent vehicle for pure electric driving in the traffic jam section, and the preset power generation power with the highest power generation power is used to calculate the power generation time of the range extender.

[0084] Exemplarily, the power generation time of the range extender is calculated according to the following calculation formula: Wherein, J represents the supplementary electric energy, and P max represents the preset power generation power with the highest power generation power.

[0085] The embodiment provides a way to accurately calculate the power generation time of the range extender, which can quickly calculate the power generation time of the range extender through simple mathematical calculation, so that the whole calculation process is more convenient and fast.

[0086] In an example embodiment of the present application, how to calculate the first detected battery percentage corresponding to the traffic jam road section is described in detail, please refer to Figure 6 , Figure 6 is another flowchart of the control method of the range extender in the traffic jam road condition based on any of the example embodiments in Figures 1 to 5 . The control method further comprises S610-S630 in S120, which are described in detail as follows:

[0087] S610: obtaining the total battery capacity and the preset battery percentage corresponding to the starting time of the range extender.

[0088] S620: calculating the first battery percentage according to the total battery capacity, the preset battery percentage, the traffic jam road section and the average speed in the traffic jam road condition.

[0089] S630: summing the first battery percentage and the preset error battery percentage, and taking the sum as the first detected battery percentage.

[0090] An example embodiment is described as follows: the first detected battery percentage is calculated according to the following calculation formula:

[0091]

[0092] SOC1 = SOC0 + SOC deta ;

[0093] Wherein, SOC0 represents the first battery percentage; SOC1 represents the first detected battery percentage; SOC deta represents the preset error battery percentage; E represents the total battery capacity; SOC str represents the preset battery percentage corresponding to the starting time of the range extender; e1 represents the average power consumption of the traffic jam road section, which can be determined according to the average speed in the traffic jam road condition; and S1 represents the traffic jam road section.

[0094] If SOC2 ≤ SOC str + SOC deta or SOC str + SOC deta <SOC2 < SOC0 + SOC deta , i.e. the target battery percentage is less than the first detected battery percentage, it indicates that the existing residual energy at the vehicle end cannot meet the pure electric driving requirement of the vehicle in the traffic jam road section, and the range extender needs to be controlled to generate power before the vehicle runs to the starting position of the traffic jam road section to obtain the required supplemental energy in the traffic jam road section. If SOC2 ≥ SOC0 + SOC detaIf the result is true, it means that the existing residual energy is sufficient to meet the requirement of pure electric driving of the vehicle in the congested road section, and the range extender does not need to be started in advance.

[0095] The preset error battery percentage is introduced in the embodiment, and an error threshold is added to the first detected battery percentage. Since the detection range of the first detected battery percentage with the error threshold is wider, accidental errors can be reduced to some extent. By comparing the target battery percentage with the size of the target battery percentage, it can be more accurately determined whether the range extender is controlled to generate power before the vehicle runs to the start position of the congested road.

[0096] In an example embodiment of the present application, how to calculate the first detected battery percentage corresponding to the congested road section is introduced in detail, please refer to Figure 7 , Figure 7 is another flowchart of the control method of the range extender in the congested road condition shown in any of the example embodiments. Figures 1 to 5 The control method further includes S710-S720 in S130, which are introduced in detail as follows:

[0097] S710: Obtain the total battery capacity and the current battery percentage.

[0098] The total battery capacity and the current battery percentage are data that can be collected in real time by the execution end.

[0099] S720: According to the total battery capacity, the current battery percentage, the driving road section and the current average speed, the target battery percentage corresponding to the running of the vehicle to the start position of the congested road is calculated.

[0100] The target battery percentage is calculated according to the following calculation formula:

[0101]

[0102] Wherein, SOC2 represents the target battery percentage; E represents the total battery capacity; SOC act represents the current battery percentage; e2 represents the average power consumption of the current driving road section, which can be determined according to the current average speed; S2 represents the driving road section.

[0103] The embodiment provides a way to accurately calculate the target battery percentage. The total battery capacity, the current battery percentage, the driving road section and the current average speed are quickly calculated through a simple calculation formula to speed up the progress of the calculation process.

[0104] The application scenarios of the above-mentioned multiple control methods are exemplarily illustrated in another exemplary embodiment of the present application, and details can be referred to Figure 8 , Figure 8 is a schematic diagram of the application scenarios of the control method of the present application. It includes a vehicle 100, a controller 200 and a third-party platform 300, which can be connected through wireless communication, and the present application does not limit the connection mode between them.

[0105] The vehicle 100 can send its own position information and related working condition information to the third-party platform 300, and the third-party platform 300 generates the traffic jam road condition information sent to the controller 200 according to the relevant information received from the vehicle 100 and the driving data and real-time road information of other vehicles collected, so that the controller 200 executes the control method of the range extender in the traffic jam road condition as shown in the above-mentioned various exemplary embodiments. The following is exemplarily illustrated:

[0106] The controller 200 receives the traffic jam road condition information; wherein the traffic jam road condition information includes a traffic jam section corresponding to the traffic jam start position to the traffic jam end position, the average vehicle speed of the vehicle 100 in the traffic jam section, and the driving section and the current average speed from the current time vehicle position to the traffic jam start position; according to the traffic jam section and the average vehicle speed of the traffic jam, the first detected battery percentage is calculated; according to the driving section and the current average speed, the target battery percentage corresponding to the running of the vehicle 100 to the traffic jam start position is calculated; if the detected target battery percentage is less than the first detected battery percentage, the range extender is controlled to generate power before the vehicle 100 runs to the traffic jam start position, so as to obtain the supplementary electric energy required by the vehicle 100 in the traffic jam section. As Figure 9 shown, Figure 9 is a schematic diagram of the change of the battery percentage during the running of the vehicle and the existing vehicle.
