[0031] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0032] The energy consumption of the whole vehicle is one of the core evaluation indicators of new energy vehicles. Both OEMs and users are very concerned about the energy consumption performance of vehicles. As the main component of the energy consumption of the whole vehicle, the energy consumption of the electric drive system is affected by many parameters.

[0033] Therefore, during the vehicle development process, simulation software is used to evaluate the energy consumption of samples at different development stages. The energy consumption change of the electric drive system is calculated, and the energy consumption and endurance change of the vehicle are further evaluated.

[0034] However, the use of simulation software requires a lot of computing resources, has a huge number of parameters, and consumes a lot of time, which affects the efficiency of vehicle energy consumption assessment.

[0035] To solve the above problems, the embodiments of this specification provide a vehicle energy consumption evaluation system, and the vehicle energy consumption evaluation method provided in the embodiments of this specification is applied to the vehicle energy consumption evaluation system. The evaluation system acquires parameters under different working conditions, establishes an energy consumption relationship based on specific parameters, and realizes the energy consumption evaluation process in parameter dimension.

[0036] Specifically, the vehicle information interaction system may include: Figure 1The operating environment formed by the server 110 and the vehicle 120 in the embodiment. The vehicle 120 communicates with the server 110 through a network connection. The functions implemented in the vehicle 120 can be local processing by the vehicle 120, or the vehicle 120 receives information and uploads it to the server 110 in the cloud, and the server 110 in the cloud processes and sends it to the vehicle 120. Among them, the server 110 can be an electronic device with certain computing and processing capabilities. It can have a network communication module, a processor, and a memory, etc. Of course, the server 110 can also refer to the software running in the electronic device. The server 110 can also be a distributed server, which can be a system with multiple processors, memories, network communication modules, etc. operating in collaboration. Alternatively, the server 110 can also be a cluster formed by several servers 110. Alternatively, with the development of science and technology, the server 110 can also be a new technical means that can realize the corresponding functions of the implementation method of the specification. For example, it can be a new form of "server" based on quantum computing.

[0037] Specifically, when the energy consumption evaluation is performed based on the above evaluation system, the road conditions are determined; then the driving information of the vehicle under the road conditions is obtained, and the corresponding acceleration parameters are determined through the speed parameters in the driving information; and the whole vehicle resistance is obtained by parameter configuration based on the speed parameters and the acceleration parameters, so as to determine the change in the whole vehicle resistance after the whole vehicle parameters of the vehicle change according to the whole vehicle resistance; then the power change information of the vehicle is represented according to the driving information, the whole vehicle resistance and the change in the whole vehicle resistance, so as to determine the change in the energy consumption of the vehicle's electric drive system through the power change information; and then the energy consumption performance of the vehicle after the whole vehicle parameters change is evaluated based on the energy consumption change. Thus, the energy consumption evaluation process of the parameter dimension is realized, and by analyzing the influence mechanism of different parameters on the energy consumption of the electric drive system, the calculation logic and calculation process are optimized, unnecessary repeated solutions are avoided, and the dependence on simulation software and experimental tests is reduced, so as to achieve the effect of quickly and efficiently evaluating the change in the energy consumption of the electric drive system.

[0038] Based on the above concept, an embodiment of the present specification provides a method for evaluating vehicle energy consumption. The following will provide an exemplary description of the method for evaluating vehicle energy consumption provided in the embodiment of the present specification in conjunction with the accompanying drawings.

[0039] To be applied to Figure 1 Taking the server in the example, some embodiments of this specification exemplify the method for evaluating the vehicle energy consumption, such as Figure 2 As shown, Figure 2 A flow chart of a method for evaluating vehicle energy consumption provided in accordance with an embodiment of the present specification; the method for evaluating vehicle energy consumption includes:

[0040] 201. Determine road conditions.

[0041] In this embodiment, the road condition is the road condition used to evaluate the energy consumption of the electric drive system. The energy consumption level of the vehicle is characterized by testing the amount of electric energy consumed by the electric vehicle under typical road condition inputs. Such as CLTC (China Light-duty Vehicle Test Cycle), WLTC (World Light Vehicle Test Cycle), NEDC (New European Driving Cycle), etc. In addition, the road condition can also be a special condition with other custom parameters, which is not limited here.

[0042] 202. Acquire driving information of the vehicle under road conditions, and determine corresponding acceleration parameters according to speed parameters in the driving information.

[0043] In this embodiment, since the road conditions determine the vehicle speed values ​​(speed parameters) at different times, the vehicle acceleration (acceleration parameters) corresponding to different times can be further calculated through the condition curve corresponding to the driving information.

[0044] Specifically, the acceleration parameter can be calculated by the relationship between the difference between the values ​​of adjacent speed points and the time interval. The formula is as follows:

[0045]

[0046] Among them, a t is the acceleration value at time t, in m / s 2 ; t′ is the time interval, unit is s;, v t+t′ 、v t-t′ It is the speed value at time t+t′ and time tt′, in m / s.

[0047] Furthermore, multiple speed parameters may be used to determine the acceleration parameters, that is, the acceleration value may be calculated by selecting the time to be determined and several speed points before and after the time to be determined, and by curve fitting and derivative calculation, thereby improving the accuracy of the acceleration parameters.

[0048] 203. Parameter configuration is performed based on the speed parameter and the acceleration parameter to obtain the whole vehicle resistance, so as to determine the change in the whole vehicle resistance after the whole vehicle parameters of the vehicle are changed according to the whole vehicle resistance.

[0049] In this embodiment, the torque output by the electric drive system of the electric vehicle is transmitted to the wheel end via the half shaft, thereby overcoming the resistance of the entire vehicle to drive the vehicle. Therefore, in order to evaluate the energy consumption change of the electric drive system, it is necessary to determine the resistance of the entire vehicle corresponding to different input working conditions at different times.

[0050] Specifically, this embodiment determines the whole vehicle resistance by constructing a multi-dimensional equation and simulating the resistance of the sliding scene. For the process of constructing the multi-dimensional equation, firstly, the external resistance dimension of the vehicle is configured based on the speed parameter and the acceleration parameter to obtain the external resistance, which includes the rolling resistance of the whole vehicle, the air resistance of the whole vehicle and the ramp resistance of the whole vehicle; then, the internal resistance dimension of the vehicle is configured according to the component configuration of the vehicle to obtain the internal resistance, which includes the acceleration resistance of the whole vehicle and the mechanical internal resistance of the whole vehicle; then, the external resistance and the internal resistance are combined to obtain the whole vehicle resistance; thus, the multi-dimensional resistance construction combining the internal and external is realized.

[0051] It is understandable that for internal resistance, due to the different mechanical structures of different vehicles, especially the rich variety of transmission structures, it is necessary to design the composition of internal resistance in a targeted manner. Therefore, to determine the internal resistance, the transmission components in the component configuration of the vehicle can be first determined to determine the resistance torque corresponding to the transmission components; then the mechanical internal resistance of the whole vehicle can be determined according to the resistance torque corresponding to the transmission components; and the rotational inertia information corresponding to the reducer in the component configuration of the vehicle can be obtained; then the acceleration resistance of the whole vehicle can be determined based on the rotational inertia information; and then the internal resistance can be obtained by combining the acceleration resistance of the whole vehicle and the mechanical internal resistance of the whole vehicle.

[0052] In one possible scenario, the following example is provided for the above process of establishing the whole vehicle resistance equation through multiple dimensions, that is, the whole vehicle resistance equation consists of the following parts: external resistance (whole vehicle rolling resistance equation, whole vehicle air resistance equation, whole vehicle slope resistance equation) and internal resistance (whole vehicle acceleration resistance equation, whole vehicle mechanical internal resistance equation).

[0053] Specifically, the drag equation for the entire vehicle is as follows:

[0054] F d (t) = F f +F w +F i +F j +F m

[0055] Among them, F d (t) is the vehicle resistance at time t, in N; F f is the rolling resistance of the vehicle, in N; F w is the air resistance of the vehicle, in N; F i is the slope resistance of the vehicle, in N; F j is the acceleration resistance of the whole vehicle, in N; F m It is the mechanical internal resistance of the whole vehicle, in N.

[0056] The rolling resistance equation for the whole vehicle can be expressed as:

[0057] F f =mgf

[0058] Wherein, m is the mass of the vehicle, in kg; g is the acceleration due to gravity, in N / kg; and f is the rolling resistance coefficient.

[0059] The air resistance equation for the whole vehicle can be expressed as:

[0060]

[0061] Among them, C d is the air resistance coefficient; A is the windward area of ​​the vehicle, in m 2 ;v t For speed.

[0062] The slope resistance equation for the whole vehicle can be expressed as:

[0063] F i = mgi t

[0064] Among them, i t is the slope; m is the mass of the vehicle, in kg; g is the acceleration due to gravity.

[0065] The acceleration resistance equation for the whole vehicle can be expressed as:

[0066] F j =δma t

[0067] Where δ is the rotational mass conversion factor; m is the vehicle mass; a t is the acceleration.

[0068] Specifically, the determination of the rotational mass conversion coefficient can be:

[0069]

[0070] Where r is the rolling radius of the tire, in meters; ∑I w The total moment of inertia of the rotating parts after the reducer, in kg·m 2 ;i g is the speed ratio of the reducer; η T is the transmission system efficiency; ∑I m The total moment of inertia of the rotating parts before the reducer, in kg·m 2 .

[0071] The mechanical internal resistance equation for the entire vehicle can be expressed as:

[0072]

[0073] Among them, T bearis the caliper resistance torque of the whole vehicle, in Nm; T caliper is the vehicle bearing resistance moment, in Nm; T drag It is the resistance torque of the vehicle transmission system, in Nm, such as the drag torque of the non-drive motor.

[0074] On the other hand, for the process of determining the resistance of the whole vehicle by simulating the resistance of the sliding scene, that is, the speed parameters are obtained by the vehicle during the road sliding process. First, the parameters for friction are configured based on the speed parameters and acceleration parameters of the vehicle during the road sliding process to obtain the road resistance; then, the parameters for the driving scene are configured based on the speed parameters and acceleration parameters of the vehicle during the road sliding process to obtain the scene resistance; and then the road resistance and scene resistance are combined to obtain the whole vehicle resistance. This is because the road resistance of the vehicle is often obtained by the sliding method in engineering. When the whole vehicle slides on the road, the speed will gradually decrease due to the effects of rolling resistance, air resistance, friction resistance of the transmission mechanism, etc. Therefore, the road resistance of the vehicle can be obtained by combining the whole vehicle parameters and the speed value during the sliding process. This resistance value can be regarded as the sum of the rolling resistance of the whole vehicle, the air resistance of the whole vehicle, and the mechanical internal resistance of the whole vehicle. Its expression is as follows:

[0075] F road (t) = f a +f b v t +f c v t 2

[0076] Among them, F road (t) is the road resistance at time t, in N; f a is the road resistance constant term that is independent of vehicle speed, in N; f b is the road resistance coefficient related to the first-order term of vehicle speed, in N / (m / s); f c is the road resistance coefficient related to the quadratic term of speed, in N / (m / s) 2 .

[0077] Furthermore, in addition to rolling resistance, air resistance, and mechanical internal resistance, the vehicle is also affected by the environment in specific scenarios, such as slope resistance and acceleration resistance. Therefore, the calculation method of the vehicle resistance determined by the road sliding method is as follows:

[0078] F d (t) = F road (t)+F i +F j =f a +f b v t +f c v t2 +mgi t +δma t

[0079] Among them, F road (t) is the road resistance at time t; F i is the slope resistance of the vehicle, in N; F j is the acceleration resistance of the whole vehicle; f a is the road resistance constant term that is independent of vehicle speed, in N; f b is the road resistance coefficient related to the first-order term of vehicle speed, in N / (m / s); f c is the road resistance coefficient related to the quadratic term of speed, in N / (m / s) 2 ;i t is the slope; m is the vehicle mass, in kg; g is the acceleration due to gravity; δ is the rotational mass conversion coefficient.

[0080] It can be understood that, since the above two methods of determining the vehicle resistance are both performed through speed parameters, the vehicle resistance can be fitted into the following formula:

[0081] F d (t) = f0 + f1v t +f2v t 2

[0082] Among them, f0 is the vehicle resistance constant term that is independent of vehicle speed, unit N; f1 is the vehicle resistance coefficient related to the first-order term of vehicle speed, unit N / (m / s); f2 is the vehicle resistance coefficient related to the second-order term of speed, unit N / (m / s) 2 .

[0083] Specifically, when the vehicle resistance is determined by establishing the vehicle resistance equation in multiple dimensions:

[0084]

[0085] f1=0

[0086]

[0087] In addition, when the vehicle resistance is obtained by sliding on the road:

[0088] f0=f a +mgi t +δma t

[0089] f1=f b

[0090] f2=f c

[0091] Among them, f0 is an independent term, f1 is a linear term and f2 is a quadratic term.

[0092] Through the configuration of the above polynomials, the two resistance solution methods are reduced to the same calculation expression, reducing the complexity of product calculation and subsequent software design.

[0093] Furthermore, based on the expression of the above polynomial, when calculating the change in vehicle resistance, the above polynomial can be used, that is, after the parameters are configured based on the speed parameters and the acceleration parameters to obtain the vehicle resistance expressed by the polynomial; determine the irrelevant terms, linear terms and quadratic terms in the corresponding expression of the vehicle resistance; then, according to the changes in the vehicle parameters, determine the parameter changes corresponding to the irrelevant terms, linear terms and quadratic terms respectively; and then determine the vehicle resistance change based on the parameter changes corresponding to the irrelevant terms, linear terms and quadratic terms respectively.

[0094] Specifically, the change in vehicle parameters is caused by the change in vehicle resistance as vehicle mass, frontal area, rolling resistance coefficient and other parameters change. In order to evaluate the impact of vehicle design parameter changes on the energy consumption of the electric drive system, the present invention will first calculate the change in vehicle resistance and divide it into three parts: the change in vehicle speed-independent items Δf0, the change coefficient of the first-order item of vehicle speed Δf1, and the change coefficient of the second-order item of vehicle speed Δf2.

[0095] The calculation formula for the change in the speed-independent term Δf0 is:

[0096] Δf0=f″0-f′0

[0097] Wherein, f′0 is the vehicle resistance constant term independent of vehicle speed before parameter change, unit is N; f″0 is the vehicle resistance constant term independent of vehicle speed after parameter change, unit is N.

[0098] Specifically, the calculation formula of the first-order change coefficient Δf1 of the vehicle speed is:

[0099] Δf1=f″1-f′1

[0100] Wherein, f′1 is the vehicle drag coefficient related to the first-order term of vehicle speed before the parameter change, in N / (m / s); f″1 is the vehicle drag coefficient related to the first-order term of vehicle speed after the parameter change, in N / (m / s);

[0101] Specifically, the calculation formula of the vehicle speed quadratic term change coefficient Δf2 is:

[0102] Δf2=f″2-f′2

[0103] Wherein, f′2 is the vehicle drag coefficient related to the quadratic term of vehicle speed before the parameter change, in N / (m / s)2; f″2 is the vehicle drag coefficient related to the quadratic term of vehicle speed after the parameter change, in N / (m / s2);

[0104] In summary, the calculation formula for the change in vehicle resistance can be described as:

[0105] ΔF d (t) = Δf0 + Δf1v t +Δf2v t 2

[0106] Among them, Δf0 is the change in the irrelevant term of vehicle speed, that is, the irrelevant term; Δf1 is the change in the first-order term of vehicle speed, that is, the sum of the first-order terms; Δf2 is the change in the second-order term of vehicle speed, that is, the quadratic term.

[0107] It is understandable that by directly solving the variation, that is, solving the variation of vehicle resistance first, and then obtaining the variation of power and energy consumption, this is different from the design idea of ​​solving the energy consumption values ​​before and after the design parameters are changed and then evaluating the variation of energy consumption.

[0108] 204. The power change information of the vehicle is represented according to the driving information, the whole vehicle resistance and the whole vehicle resistance change, so as to determine the energy consumption change of the electric drive system of the vehicle through the power change information.

[0109] In this embodiment, the energy consumption change of the vehicle's electric drive system is reflected by the power change. Since the vehicle adopts the form of electric drive, the power that needs to be converted to the electric end is more accurate. That is, for the process of calculating the energy consumption change of the electric drive system and the vehicle endurance change using information such as road conditions, vehicle resistance, and vehicle resistance change; first determine the vehicle power change corresponding to the vehicle based on driving information, vehicle resistance, and vehicle resistance change; then obtain the efficiency information of the electric drive system configured for the vehicle; and determine the electric end power change of the electric drive system based on the vehicle power change, vehicle resistance, and efficiency information; then determine the corresponding mileage data in the driving information; and then represent the vehicle's power change information through the electric end power change, so as to determine the energy consumption change of the vehicle's electric drive system through the power change information and mileage data.

[0110] Specifically, for the above process of establishing the vehicle power change equation according to the vehicle speed and the vehicle resistance change, the vehicle power change equation is as follows:

[0111] ΔP d (t) = ΔF d (t)v t

[0112] Where ΔPd It is the change of vehicle power at time t, in W.

[0113] Regarding the process of establishing the electric end power variation equation of the electric drive system according to the whole vehicle power variation, the whole vehicle resistance and the comprehensive efficiency of the electric drive system, the electric end power variation equation of the electric drive system is as follows:

[0114]

[0115] Where ΔP m (t) is the power change of the electric drive system at the time t, in W; η m It is the comprehensive efficiency of the electric drive system, that is, efficiency information.

[0116] Optionally, the power change ΔP of the electric drive system m It is also calculated using the comprehensive driving efficiency and comprehensive recovery efficiency of the electric drive system or using the efficiency of the electric drive system at each moment.

[0117] Specifically, the determination of efficiency information can be carried out in the following ways: 1. Measurement of input and output power: First, it is necessary to measure the DC output power of the battery, the AC output power of the motor controller, and the mechanical power of the motor. These data can be measured by a power analyzer. 2. Operating cycle efficiency evaluation: Based on the calculation of the comprehensive efficiency of the motor of the vehicle operating cycle (such as CLTC, WLTC), the motor high efficiency area is optimized by calculating the proportion of mechanical energy required by the integrated electric drive system. For example, by drawing efficiency curves under different operating conditions, and selecting the efficiency points under the corresponding operating conditions for interpolation calculations. 3. Static and dynamic efficiency tests: At the static operating point, the percentage of the efficient working area of ​​the drive motor system (efficiency not less than 85%) to the total working area should meet the requirements of the product technical documents. Under dynamic conditions, the highest efficiency of the drive motor system in all operating conditions should not be lower than the value determined by negotiation between the manufacturer and the user. The specific method depends on the actual scenario.

[0118] Furthermore, for the process of establishing an electric drive system energy consumption change equation based on the electric drive system power terminal change and the mileage data; the electric drive system energy consumption change equation is as follows:

[0119]

[0120] Where, ΔE m It is the change in energy consumption of the electric drive system, in kWh / 100km.

[0121] In one possible scenario, when the overall efficiency of the electric drive system changes, the energy consumption of the electric drive system will also change. That is, if the efficiency information of the electric drive system changes, the efficiency difference corresponding to the electric drive system is determined; and then the power change at the electric end is updated based on the efficiency difference.

[0122] Specifically, the method for evaluating the change in energy consumption of the electric drive system when the efficiency information changes is as follows: let f″0=0, f″1=0, f″2=0 in step 203, and replace the equation for the change in power at the electric end of the electric drive system in step 204 with the following equation, and the remaining processing methods are the same as the above embodiments.

[0123] Correspondingly, the equation for the power change at the electric end of the electric drive system is as follows:

[0124]

[0125] Among them, η m ′ is the efficiency value of the electric drive system before the comprehensive efficiency changes; η m ″ is the efficiency value after the comprehensive efficiency of the electric drive system changes.

[0126] Since the efficiency information directly reflects the impact of different vehicle configurations, the power change at the electric end can be quickly calculated through the dimension of the efficiency information parameters, thereby conducting the subsequent energy consumption change evaluation process.

[0127] 205. Based on the energy consumption change, the energy consumption performance of the vehicle after the vehicle parameters change is evaluated.

[0128] In this embodiment, the energy consumption performance of the vehicle after the vehicle parameters change can be evaluated by a comprehensive evaluation process of calculating the change in vehicle endurance caused by the change in electric drive energy consumption using the change in electric drive system energy consumption, vehicle energy consumption and battery available power.

[0129] Specifically, for the comprehensive evaluation process, first obtain the corresponding power information of the vehicle; then configure the power information based on the energy consumption change to obtain the vehicle range change; and then evaluate the energy consumption performance of the vehicle after the vehicle parameters change based on the energy consumption change and the vehicle range change. Therefore, for evaluating the impact of the electric drive system energy consumption change on the vehicle range, the vehicle range change can be expressed as:

[0130]

[0131] Among them, ΔBER is the change in vehicle range, in km; E b EC is the available power of the battery, in kWh; DC It is the energy consumption of the whole vehicle before the parameter changes, which can be the design value or the measured value, in kWh / 100km.

[0132] In a possible scenario, the corresponding evaluation information of the vehicle can be obtained through the above embodiment. Specifically, through the above embodiment, after two road coasting tests for a certain vehicle model, the road coasting results can be used to quickly evaluate the impact of the difference in the two coasting resistance values ​​on the energy consumption of the vehicle electric drive system and the vehicle endurance under the CLTC working condition.

[0133] Furthermore, in order to further simulate the impact of external environmental factors on energy consumption, such as temperature, altitude, humidity, etc., distributed multi-environment warehouse collaborative simulation can also be performed, such as Figure 3 As shown, Figure 3 A scenario diagram of another method for evaluating vehicle energy consumption provided for one embodiment of this specification; that is, obtaining driving information of a vehicle under special working conditions configured in multiple environmental bins through the illustrated network architecture, wherein different environmental bins are located in different geographical regions; then determining the comprehensive energy consumption change corresponding to the driving information under special working conditions; and then evaluating the energy consumption performance of the vehicle after the vehicle parameters change based on the comprehensive energy consumption change. This can improve the accuracy of energy consumption evaluation.

[0134] This embodiment evaluates the change in energy consumption of the electric drive system through algebraic operations, and has low requirements for computing resources. Therefore, the software toolization of the design idea can be quickly realized. It is less difficult to embed into simulation software or test equipment. Furthermore, it can also be embedded in the vehicle operating system to estimate the vehicle energy consumption and endurance in combination with future road conditions. And by directly calculating the change in vehicle resistance before and after the design parameters are changed, the power change and energy consumption change are evaluated. Therefore, only a single solution is required to obtain the change in energy consumption of the electric drive system. Repeated simulation or repeated experiments are avoided, reducing the difficulty and complexity of solving the problem.

[0135] In summary, this embodiment determines the road conditions; then obtains the driving information of the vehicle under the road conditions, and determines the corresponding acceleration parameters through the speed parameters in the driving information; and performs parameter configuration based on the speed parameters and acceleration parameters to obtain the vehicle resistance, so as to determine the change in the vehicle resistance after the vehicle parameters change according to the vehicle resistance; then represents the power change information of the vehicle according to the driving information, the vehicle resistance and the change in the vehicle resistance, so as to determine the change in the energy consumption of the vehicle's electric drive system through the power change information; and then evaluates the energy consumption performance of the vehicle after the vehicle parameters change based on the energy consumption change. Thus, the energy consumption evaluation process of the parameter dimension is realized, and the energy consumption change of the electric drive system is evaluated by using algebraic operations by analyzing the influence mechanism of different parameters on the energy consumption of the electric drive system, thereby reducing the dependence on simulation software and experimental tests, reducing the resource requirements for software tools and test equipment, and improving the efficiency of vehicle energy consumption evaluation.
