[0069] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0070] In conjunction with the accompanying drawings, an energy management method, device, storage medium and vehicle for an extended-range vehicle provided in an embodiment of the present application are described in detail through specific embodiments and their application scenarios.

[0071] Figure 1 is a flowchart of the steps of an energy management method for an extended-range vehicle provided in an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0072] Step 101, in response to a user's instruction to plan the remaining journey from the vehicle to the destination, the order of proposing bargaining game solutions among the battery and the range extender in the vehicle is determined according to a judgment result of whether the current remaining battery power of the vehicle can complete the remaining journey and / or the current driving condition of the vehicle.

[0073] It should be noted that, in the embodiment of the present application, when the driver has a charging demand, the destination may be the location of the charging facility that is closest to the current location of the vehicle and is available.

[0074] The driver obtains the charging facilities through the navigation system on the vehicle, that is, the vehicle will receive the driver's charging facility query instruction. When the vehicle receives the driver's charging facility query instruction, it obtains all the charging facilities within the preset range from the current location of the vehicle and the time to travel from the current location of the vehicle to each charging facility, and further determines whether there is a charging facility that is closest and available within the preset range from the current location of the vehicle. Among them, the preset range is the range of a circle with the current location of the vehicle as the center and the preset distance as the radius. By setting the preset range, it can be more quickly determined whether there is a charging facility that is closest and available to the current location of the vehicle.

[0075] If there is a nearest usable charging facility within a preset range from the current location of the vehicle, the power consumed by the vehicle from the current location to the destination and the current remaining battery power of the vehicle are further used to determine whether the vehicle's current remaining battery power can complete the remaining journey, where the remaining journey is the journey from the current location of the vehicle to the destination. At the same time, the vehicle's current driving condition is determined based on the KPCA (Kernel Principal Component Analysis) strategy. The vehicle's driving condition refers to the type of road the vehicle is driving on, and the vehicle's driving condition includes driving on a main road and driving on an expressway.

[0076] Based on the judgment result of whether the current remaining battery power of the vehicle can complete the remaining journey and / or the current driving condition of the vehicle, it is determined whether the range extender in the vehicle or the battery in the vehicle will give priority to proposing a bargaining game solution, that is, the order in which the bargaining game solutions are proposed. By determining the order in which the bargaining game solutions are proposed, the fuel consumption of the range extender and the loss of the battery can be taken into account in different scenarios to allocate the required power of the whole vehicle, thereby achieving the goal of reducing the fuel consumption of the range extender while also improving the battery life.

[0077] If there is no destination within the preset range from the current vehicle location, the vehicle's current driving condition is identified based on the KPCA strategy.

[0078] Specifically, Figure 2 As shown, the real-time continuous speed of the vehicle traveling on the trunk road and the real-time continuous speed of the vehicle traveling on the expressway are respectively obtained within a preset time interval.

[0079] The motion characteristics representing the vehicle traveling on the main road are calculated according to the real-time continuous speed of the vehicle traveling on the main road, and the motion characteristics representing the vehicle traveling on the expressway are calculated according to the real-time continuous speed of the vehicle traveling on the expressway, wherein the motion characteristics may include average speed (km / h), maximum speed (km / h), maximum acceleration (m / s2 )、Maximum deceleration (m / s 2 ), average deceleration (m / s 2 ), number of stops, stop time (s), low speed time (10-25Km / h) / total time (%), medium speed time (60-90Km / h) / total time (%) and high speed time (>90Km / h) / total time (%), motion characteristics are represented by X={x1,x2,...,x 10}express.

[0080] In the KPCA strategy, the first step is to calculate the kernel matrix. Specifically, the motion features are substituted into formula (1) to obtain the kernel matrix. Formula (1) is as follows:

[0081] K(x i ,x j )=( <x i ,x j >+d) p Formula (1)

[0082] Among them, x i , x j For X = {x1, x2, ..., x 10}, d and p are hyperparameters, K(x i , x j ) is the kernel matrix.

[0083] The second step is to calculate the centralized kernel matrix. Specifically, K(x i , x j ) is substituted into formula (2) to obtain the centralized kernel matrix. Formula (2) is as follows:

[0084]

[0085] Among them, I N is an n×n matrix, K is K(x i , x j ), is a centralized core matrix.

[0086] The third step is to select the main eigenvector. Specifically, for K(x i , x j ) is decomposed to obtain the eigenvalue λ and the eigenvector α corresponding to the eigenvalue, and λ is substituted into formula (3) to obtain the cumulative contribution rate. Formula (3) is as follows:

[0087]

[0088] Among them, λ i , i=(1,2,...,n) represents K(xi , x j ) has n eigenvalues, λ K K(x i , x j ) in the Kth eigenvalue, E k is the cumulative contribution rate.

[0089] According to the cumulative contribution rate, the eigenvalues ​​with high cumulative contribution rate are retained, the eigenvalues ​​with low cumulative contribution rate are removed, and the eigenvectors α corresponding to the first k eigenvalues ​​are selected. i ,i∈[1,k] is taken as the main eigenvector.

[0090] The fourth step is to select features. Specifically, the centralized kernel matrix and the principal eigenvector α i Substitute into formula (4) to obtain the selected features. Formula (4) is as follows:

[0091]

[0092] in, is the centralized kernel matrix, α i ,i∈[1,k] is the main eigenvector, The selected features.

[0093] The K-means clustering method is used based on the selected features to classify the vehicle's driving conditions. The typical driving conditions of the extended-range electric vehicle are constructed based on the classification results, so that it can be obtained whether the current vehicle is driving on a main road or a freeway.

[0094] Step 102, according to the order in which the bargaining game schemes are proposed, bargaining game schemes are proposed for the battery and the range extender respectively, until the bargaining game scheme for the battery and the bargaining game scheme for the range extender reach a Nash equilibrium point, and a target scheme is obtained; wherein the bargaining game scheme for the battery is determined based on the current vehicle power demand, the expected output power of the range extender, and the expected output power of the battery, and the bargaining game scheme for the range extender is determined based on the current vehicle power demand, the expected output power of the range extender, and the expected output power of the battery.

[0095] It should be noted that in the embodiment of the present application, the bargaining game scheme includes the vehicle's current vehicle power demand, the expected output power of the range extender, and the expected output power of the battery. The target scheme is a bargaining game scheme accepted by both the range extender and the battery, and the vehicle's current vehicle power demand is allocated according to this bargaining game scheme, including the vehicle's current vehicle power demand, the target output power of the range extender, and the target output power of the battery.

[0096] During the bargaining game process, according to the order in which the bargaining game plans are proposed, the range extender and the battery take turns proposing bargaining game plans for bargaining game until both the range extender and the battery can accept the bargaining game plan. At this time, the bargaining game process reaches the Nash equilibrium point, and the bargaining game ends. The bargaining game plan at this time is the target plan.

[0097] Step 103 : Allocate target output power of the battery and the range extender according to the target solution.

[0098] It should be noted that in the embodiment of the present application, after the target solution is determined, the vehicle will allocate the output power of the battery and the output power of the range extender according to the target solution.

[0099] This application implements different energy management strategies based on the judgment result of whether the current remaining battery power of the vehicle can complete the remaining journey and / or the current driving condition of the vehicle, so that the vehicle can have the best overall power and fuel economy under different operating conditions, and also takes into account the loss of the battery, thereby reducing the driving cost of the vehicle. This application determines the allocation plan of the power required by the whole vehicle through the bargaining game between the range extender and the battery, and can take into account the fuel consumption of the range extender and the life of the battery at the same time to obtain an optimal target plan, thereby achieving the goal of reducing the fuel consumption of the range extender while improving the battery life. This application determines whether there are charging facilities within a preset range from the current location of the vehicle, and takes into account how to use the clean and cheap electricity in the charging facilities, thereby achieving the technical purpose of reducing the fuel consumption of the vehicle. This application uses the KPCA strategy to identify the driving condition of the vehicle, which can improve the accuracy of the vehicle driving condition identification.

[0100] Furthermore, in the embodiment of the present application, the method may further include the following steps:

[0101] The amount of electricity consumed by the vehicle to reach the destination and the current remaining battery power of the vehicle are obtained in advance.

[0102] It should be noted that in the embodiment of the present application, after the destination is confirmed, it is necessary to determine whether the current remaining battery power of the vehicle can complete the remaining journey, and the remaining journey is the journey from the current location of the vehicle to the destination.

[0103] Specifically, the amount of electricity consumed by the current vehicle when traveling to the destination is obtained, and the current remaining battery power of the vehicle is obtained through the vehicle's dashboard.

[0104] When the power consumed by the vehicle to reach the destination is less than or equal to the current remaining battery power, the current remaining battery power of the vehicle can complete the remaining journey.

[0105] When the amount of electricity consumed by the vehicle to reach the destination is greater than the current remaining battery power, the current remaining battery power of the vehicle cannot complete the remaining journey.

[0106] It should be noted that in the embodiment of the present application, after obtaining the power consumed by the vehicle to the destination and the current remaining battery power of the vehicle, it is possible to determine whether the current remaining battery power of the vehicle can complete the remaining journey based on the numerical value between the power consumed by the vehicle to the destination and the current remaining battery power of the vehicle. Specifically, if the power consumed by the current vehicle to the destination is less than or equal to the current remaining battery power, it means that the current remaining battery power of the vehicle is sufficient to enable the vehicle to travel from the current location to the destination, and the current remaining battery power of the vehicle can complete the remaining journey.

[0107] If the power consumed by the current vehicle to travel to the destination is greater than the current remaining battery power, it means that the current remaining battery power of the vehicle is not enough to enable the vehicle to travel from the current location to the destination, and the current remaining battery power of the vehicle cannot complete the remaining journey.

[0108] This application determines whether the vehicle's current battery remaining power can complete the remaining journey based on the power consumed by the vehicle to the destination and the vehicle's current battery remaining power, and then can provide a judgment basis for determining the order of proposing bargaining game solutions based on different judgment results.

[0109] Furthermore, in the embodiment of the present application, “pre-acquiring the amount of electricity consumed by the vehicle when traveling to the destination” may also include the following steps:

[0110] Get the remaining battery power consumed per unit mileage and the distance between the vehicle and the destination.

[0111] The amount of power consumed by the vehicle to reach the destination is determined based on the remaining battery power consumed per unit mileage and the distance between the vehicle and the destination.

[0112] It should be noted that, in the embodiment of the present application, the specific implementation process of obtaining the amount of power consumed by the vehicle to the destination is: obtaining the remaining battery power consumed per unit mileage, specifically, obtaining the historical remaining battery power consumed per unit mileage of the current vehicle, finding the average of the obtained historical remaining battery power consumed per unit mileage, and taking the average of the historical remaining battery power consumed per unit mileage as the remaining battery power consumed per unit mileage; and, obtaining the distance between the vehicle and the destination through the navigation system of the current vehicle.

[0113] Substituting the remaining battery power consumed per unit mileage and the distance between the current vehicle and the destination into formula (5), the power consumed from the current vehicle location to the destination can be obtained. Formula (5) is as follows:

[0114]

[0115] Among them, SOC req is the amount of electricity consumed by the vehicle to reach its destination, L 1d is the distance between the vehicle and the destination, The remaining battery power consumed per unit mileage.

[0116] The present application determines the amount of power consumed by a vehicle to travel to a destination based on the remaining battery power consumed per unit mileage and the current distance between the vehicle and the destination, thereby achieving the technical purpose of judging whether the current remaining battery power of the vehicle can complete the remaining journey based on the amount of power consumed by the vehicle to travel to the destination.

[0117] Furthermore, in the embodiment of the present application, step 102 may also include the following steps:

[0118] When the current remaining battery power of the vehicle can complete the remaining journey, it is determined whether the current remaining battery power is less than or equal to a preset first remaining battery power reference value.

[0119] It should be noted that, in the embodiment of the present application, if the remaining battery power is too low, the battery may be damaged, affecting the performance and life of the battery. In order to prevent the battery from being over-discharged and affecting the performance and life of the battery, a first reference value of the remaining battery power is preset. Preferably, the first reference value of the remaining battery power is 10%. The specific value of the first reference value of the remaining battery power can be adjusted later as the solution is optimized.

[0120] If the result of the judgment on whether the current remaining battery power of the vehicle can complete the remaining journey is that the current remaining battery power of the vehicle can complete the remaining journey, it is further judged whether the current remaining battery power of the vehicle is less than or equal to a preset first remaining battery power reference value.

[0121] When the current remaining battery power is less than or equal to the first remaining battery power reference value, the range extender in the vehicle preferentially proposes a bargaining game plan.

[0122] It should be noted that in the embodiment of the present application, if the current remaining battery power of the vehicle is less than or equal to a preset first remaining battery power reference value, it means that the current remaining battery power of the vehicle is at a low level. In order to prevent the battery from being over-discharged and affecting the performance and life of the battery, it is necessary to charge the battery through the range extender to increase the current remaining battery power of the vehicle. In this way, the battery can be avoided from being over-discharged. In this scenario, the range extender hopes to minimize its own fuel consumption while charging the battery. Therefore, in the bargaining game process, the range extender in the vehicle shall give priority to proposing a bargaining game plan.

[0123] If the vehicle's current battery remaining power is greater than a pre-set first battery remaining power reference value, it means that the vehicle's current remaining power is at a high level and the battery will not be over-discharged. As a result, there is no need to charge the battery through a range extender, and the vehicle's current remaining power is sufficient to enable the vehicle to travel from its current location to its destination.

[0124] The present application determines the order of proposing bargaining game plans to give priority to the range extender when the current remaining battery power of the vehicle can complete the remaining journey and the current remaining battery power is less than or equal to a first remaining battery power reference value. This allows the range extender to charge the battery to avoid excessive discharge of the battery, while also minimizing the range extender's own fuel consumption to the maximum extent.

[0125] Furthermore, in the embodiment of the present application, step 102 may also include the following steps:

[0126] When the current remaining battery power of the vehicle cannot complete the remaining journey and the current operating condition of the vehicle is traveling on a main road, it is determined whether the current remaining battery power is less than or equal to a preset second remaining battery power reference value.

[0127] It should be noted that, in the embodiment of the present application, if the remaining battery power is too low, the battery may be damaged, affecting the performance and life of the battery. In order to prevent the battery from being over-discharged and affecting the performance and life of the battery, a second reference value of the remaining battery power is preset, preferably, the second reference value of the remaining battery power is 30%. The specific value of the second reference value of the remaining battery power can be adjusted later as the solution is optimized.

[0128] When the judgment result of whether the vehicle's current battery remaining power can complete the remaining journey is that the vehicle's current battery remaining power cannot complete the remaining journey and the vehicle's current driving condition is driving on a main road, it is further judged whether the vehicle's current battery remaining power is less than or equal to a pre-set second battery remaining power reference value.

[0129] When the current remaining battery power is less than or equal to the second remaining battery power reference value, the battery in the vehicle preferentially proposes a bargaining game solution.

[0130] It should be noted that in the embodiment of the present application, if the current remaining battery power of the vehicle is less than or equal to a preset second remaining battery power reference value, it means that the current remaining battery power of the vehicle is at a low level. In order to prevent the battery from over-discharging and affecting the performance and life of the battery, it is necessary to charge the battery through the range extender to increase the current remaining battery power of the vehicle. In this way, the battery can be avoided from over-discharging. In this scenario, the battery expects the range extender to be able to bear all the current vehicle power requirements. Therefore, in the bargaining game process, the battery in the vehicle takes priority in proposing a bargaining game plan.

[0131] The present application determines the order of proposing bargaining game plans to give priority to the battery when the current remaining battery power of the vehicle is insufficient to complete the remaining journey, the current operating condition of the vehicle is traveling on a main road, and the current remaining battery power is less than or equal to a second remaining battery power reference value, so that the vehicle can travel from the current position to the destination while avoiding excessive discharge of the battery that affects the performance and life of the battery.

[0132] Furthermore, in an embodiment of the present application, the method may also include the following steps: when the current remaining battery power of the vehicle cannot complete the remaining journey and the current operating condition of the vehicle is driving on a freeway, controlling the output power of the range extender in the vehicle to be within a preset output power range.

[0133] It should be noted that in the embodiment of the present application, when the judgment result of whether the vehicle's current battery remaining power can complete the remaining journey is that the vehicle's current battery remaining power cannot complete the remaining journey and the vehicle's current driving condition is driving on a freeway, the vehicle's current vehicle power demand is relatively high, and it is necessary to control the output power of the range extender in the vehicle within a preset output power range, that is, to let the range extender operate in the optimal working range, so that the vehicle can travel from the current position to the destination.

[0134] In the present application, when the current remaining battery power of the vehicle is insufficient to complete the remaining journey and the current driving condition of the vehicle is driving on an expressway, the output power of the range extender is controlled to be within a preset output power range, so that the range extender can operate within the optimal working range, thereby not only enabling the vehicle to travel from the current position to the destination, but also minimizing the fuel consumption of the range extender itself to the maximum extent.

[0135] Further, in the embodiments of the present application, Figure 3 As shown, step 103 may further include the following steps:

[0136] Step 301, during the bargaining game process, the participant who first proposes a bargaining game plan among the battery and the range extender is regarded as the first participant, and the participant who later proposes a bargaining game plan among the battery and the range extender is regarded as the second participant, wherein the bargaining game plan is associated with the current vehicle power demand of the vehicle.

[0137] It should be noted that in the embodiment of the present application, in the bargaining game process, the range extender and the battery are respectively regarded as two participants in the bargaining game, and the participant who first proposes the bargaining game plan is regarded as the first participant, and the participant who proposes the bargaining game plan later is regarded as the second participant, that is, if the range extender first proposes the bargaining game plan, the range extender is the first participant and the battery is the second participant; if the battery first proposes the bargaining game plan, the battery is the first participant and the range extender is the second participant.

[0138] The vehicle power demand is provided by the range extender and the battery, that is, the vehicle power demand = the range extender output power + the battery output power. In the bargaining game between the range extender and the battery, the vehicle power demand is the target of the bargaining game between the two parties. The two parties take turns to propose bargaining game plans for the vehicle power demand, that is, the bargaining game plan is related to the vehicle's current vehicle power demand.

[0139] Step 302: During the bargaining game process, the first participant proposes a bargaining game plan.

[0140] Step 303: If the second participant accepts the bargaining game plan, the bargaining game ends, and the current vehicle power demand is allocated according to the bargaining game plan proposed by the first participant.

[0141] Step 304: If the second participant does not accept the bargaining game plan, the second participant proposes a bargaining game plan, and the first participant confirms whether to accept the bargaining game plan.

[0142] Step 305: If the first participant accepts the bargaining game plan, the bargaining game ends, and the current vehicle power demand is allocated according to the bargaining game plan proposed by the second participant.

[0143] Step 306: If the first participant does not accept the bargaining game plan, the step of the first participant proposing a bargaining game plan is repeated until both the first participant and the second participant accept the bargaining game plan. At this time, the bargaining game process reaches the Nash equilibrium point, and the current bargaining game plan is used as the target plan.

[0144] It should be noted that in the embodiments of the present application, Figure 4As shown, the range extender prioritizes the bargaining game plan, then the range extender is the first participant and the battery is the second participant. When the vehicle's current battery remaining power can complete the remaining journey and the current battery remaining power is less than or equal to the first battery remaining power reference value, the range extender needs to charge the battery to increase the battery's remaining power, while also minimizing fuel consumption, that is, the range extender expects to operate in the optimal working range to charge the battery. For example, the bargaining game plan prioritized by the range extender is as follows:

[0145]

[0146] Among them, F1 is the first bargaining game, P 增程器1 is the expected output power of the range extender in the first bargaining game, P 电池1 is the expected output power of the battery in the first bargaining game, P best is the output power of the range extender when it is running in the optimal working range, P req The power required for the entire vehicle.

[0147] The battery can choose to accept the bargaining game plan proposed by the range extender first, or choose to reject the bargaining game plan proposed by the range extender first. If the battery accepts the bargaining game plan proposed by the range extender first, the bargaining game ends, and the current vehicle demand power is allocated according to the bargaining game plan proposed by the range extender first, that is, P 增程器1 =P best , P 电池1 =P req -P best ; If the battery rejects the bargaining game plan put forward by the range extender first, the battery will propose a bargaining game plan. The battery expects the range extender to bear all the power required by the vehicle so that its remaining power will not decrease further. For example, the bargaining game plan put forward by the battery is as follows:

[0148]

[0149] Among them, F2 is the second bargaining game, P 增程器2 is the expected output power of the range extender in the second bargaining game, P 电池2 is the expected output power of the battery in the second bargaining game, P req The power required for the entire vehicle.

[0150] The range extender can choose to accept the bargaining game plan proposed by the battery, or it can choose to reject the bargaining game plan proposed by the battery. If the range extender accepts the bargaining game plan proposed by the battery, the bargaining game ends, and the vehicle's current vehicle demand power is allocated according to the bargaining game plan proposed by the battery, that is, P 增程器2 =P req , P 电池2=0; if the range extender rejects the bargaining game plan proposed by the battery, the steps of the range extender proposing the bargaining game plan are repeated until both the range extender and the battery can accept the bargaining game plan. At this time, from the perspective of the Rubinstein model, the bargaining game process between the range extender and the battery will eventually reach the Nash equilibrium point, as shown in the following formula:

[0151]

[0152] Among them, δ 增程器 is the discount factor of the range extender, δ 电池 is the discount factor of the battery, P best is the power output of the range extender in the optimal working range, P req The power required for the entire vehicle.

[0153] When the range extender and the battery reach the Nash equilibrium point, the bargaining game solution is P 增程器 =P best , P 电池 =P req -P best , and use this bargaining game scheme as the target scheme for the vehicle's required power.

[0154] like Figure 5 As shown, the battery first proposes a bargaining game plan, then the battery is the first participant and the range extender is the second participant. When the vehicle's current battery remaining power cannot complete the remaining journey, the vehicle's current operating condition is driving on the main road, and the current battery remaining power is less than or equal to the second battery remaining power reference value, the battery needs the range extender to charge it, and the battery expects the range extender to bear all the power required by the vehicle so that the battery's own remaining power will not decrease further. For example, the bargaining game plan proposed by the battery first is as follows:

[0155]

[0156] Among them, F1 is the first bargaining game, P 电池1 is the expected output power of the battery in the first bargaining game, P 增程器1 is the expected output power of the range extender in the first bargaining game, P req The power required for the entire vehicle.

[0157] The range extender can choose to accept the bargaining game plan proposed by the battery priority, or choose to reject the bargaining game plan proposed by the battery priority. If the range extender accepts the bargaining game plan proposed by the battery priority, the bargaining game ends, and the current vehicle demand power is allocated according to the bargaining game plan proposed by the battery priority, that is, P 电池1 =0,P 增程器1 =P req; If the range extender rejects the bargaining game plan proposed by the battery first, the range extender proposes a bargaining game plan. The range extender expects itself to operate in the optimal working range to charge the battery. For example, the bargaining game plan proposed by the range extender is as follows:

[0158]

[0159] Among them, F2 is the second bargaining game, P 电池2 is the expected output power of the battery in the second bargaining game, P 增程器2 is the expected output power of the range extender in the second bargaining game, P req is the vehicle power requirement, P best It is the output power of the range extender when it operates in the optimal working range.

[0160] The battery can choose to accept the bargaining game plan proposed by the range extender, or it can choose to reject the bargaining game plan proposed by the range extender. If the battery accepts the bargaining game plan proposed by the range extender, the bargaining game ends, and the current vehicle demand power is allocated according to the bargaining game plan proposed by the range extender, that is, P 增程器2 =P best , P 电池2 =P req -P best ; If the battery rejects the bargaining game plan proposed by the range extender, the steps of the battery proposing a bargaining game plan are repeated until both the range extender and the battery can accept the bargaining game plan. At this time, from the perspective of the Rubinstein model, the bargaining game process between the range extender and the battery will eventually reach the Nash equilibrium point.

[0161] When the range extender and the battery reach the Nash equilibrium point, the bargaining game solution is P 增程器 =P best , P 电池 =P req -P best , and use this bargaining game scheme as the target scheme for the vehicle's required power.

[0162] This application determines the distribution plan of the required power of the whole vehicle through the bargaining game between the range extender and the battery, and can take into account the fuel consumption of the range extender and the life of the battery at the same time to obtain an optimal target plan, thereby achieving the technical effect of improving the economy of the whole vehicle of the extended-range electric vehicle while reducing the fuel consumption of the range extender.
