Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.
[0053] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the vehicle energy consumption analysis equipment and may include more or fewer components than shown, or combine certain components, or have different component arrangements.
[0054] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a vehicle energy consumption analysis program.
[0055] exist Figure 1 In the vehicle energy consumption analysis device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the vehicle energy consumption analysis device of the present invention can be set in the vehicle energy consumption analysis device, and the vehicle energy consumption analysis device calls the vehicle energy consumption analysis program stored in the memory 1005 through the processor 1001 and executes the vehicle energy consumption analysis method provided in the embodiment of the present invention.
[0056] This invention provides a method for analyzing vehicle energy consumption, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of a vehicle energy consumption analysis method according to the present invention.
[0057] In this embodiment, the vehicle energy consumption analysis method includes the following steps:
[0058] Step S10: Upon receiving an energy consumption analysis request, obtain the target vehicle's load and current energy consumption.
[0059] It should be noted that the execution subject of the method in this embodiment can be a device with data processing, data acquisition and data transmission functions, such as a vehicle controller, a vehicle computer, etc., or other devices with the same or similar functions. This embodiment does not impose specific limitations on this. In this embodiment and the following embodiments, a vehicle controller will be used as an example for explanation.
[0060] It is understood that the energy consumption analysis request is used to initiate the vehicle energy consumption analysis process. The energy consumption analysis request may be automatically generated by the vehicle controller when the vehicle controller meets the requirements of the energy consumption analysis, or it may be activated by the user or staff by inputting control commands to control the vehicle controller. This embodiment does not impose specific restrictions on this.
[0061] It should be understood that vehicle load capacity includes the sum of the vehicle's own weight and the load weight; current energy consumption refers to the actual energy consumption of the vehicle during operation, including: drive energy consumption, accessory energy consumption, and loss energy consumption, etc. Among them, drive energy consumption refers to the energy consumption of the drive motor during operation, which can be calculated by the input current and voltage of the drive motor and time; accessory energy consumption refers to the sum of the operating energy consumption of each loaded accessory in the vehicle, such as the energy consumption corresponding to accessories such as air conditioning or brake pump; loss energy consumption refers to the energy consumption of electrical energy during transmission.
[0062] Furthermore, the target vehicles in this embodiment are mainly new energy vehicles. Traditional fuel vehicles generate a certain amount of electricity when they are working, which can cause interference when monitoring the energy consumption.
[0063] Furthermore, in order to obtain the accurate current energy consumption of the target vehicle, the vehicle energy consumption analysis method further includes:
[0064] Obtain the basic parameters of the target vehicle, including: the operating power of the drive motor, the power of each accessory, and the power loss;
[0065] Calculate the drive energy consumption within a preset time period based on the operating power;
[0066] Calculate the energy consumption of each accessory within a preset time period based on the power of each accessory;
[0067] The energy loss within a preset time period is calculated based on the power loss.
[0068] In a specific implementation, the basic parameters include the operating power of the drive motor, the power of each accessory, and the power loss. In addition, parameters such as the input and output current and voltage of the drive motor and the input current and voltage of each accessory may also be included. This embodiment does not impose specific limitations on these parameters.
[0069] Step S20: Determine the target energy consumption corresponding to the vehicle's load.
[0070] It is worth noting that target energy consumption refers to the theoretical energy consumption of the target vehicle under vehicle load, including: theoretical driving energy consumption, theoretical accessory energy consumption, and theoretical loss energy consumption, etc.
[0071] In practice, for the same vehicle model, each load range corresponds to a theoretical energy consumption. The correspondence can be obtained by pre-collecting changes in load, speed, mileage, battery pack output and input current, and voltage during the vehicle's operation. Finally, a vehicle load-average energy consumption (WP) table is generated based on the correspondence between the vehicle load and the vehicle's theoretical energy consumption. This table is used to query the target energy consumption corresponding to the vehicle load in energy consumption monitoring.
[0072] Step S30: Determine whether the target vehicle meets the preset energy consumption analysis conditions based on the current energy consumption and the target energy consumption.
[0073] It should be noted that the preset energy consumption analysis condition refers to the target vehicle reaching the high energy consumption mileage in two consecutive unit mileages. The high energy consumption mileage means that the actual energy consumption of the vehicle is greater than the theoretical energy consumption of the vehicle, and the ratio of actual energy consumption to theoretical energy consumption is greater than the preset ratio. The preset ratio can be set to 20%, and this embodiment does not impose specific restrictions on it.
[0074] In addition, the unit mileage is used to measure the vehicle's mileage. It can be 100 kilometers or other mileage data. This embodiment does not impose any specific restrictions on this.
[0075] In practice, when the actual energy consumption of a vehicle is detected to be greater than the theoretical energy consumption by more than 20% within two consecutive 100-kilometer intervals, the target vehicle is determined to meet the preset energy consumption analysis conditions.
[0076] Further, the step of determining whether the target vehicle meets the preset energy consumption analysis conditions based on the current energy consumption and the target energy consumption includes:
[0077] Obtain the energy consumption per unit mileage within at least two consecutive unit mileages;
[0078] The energy consumption analysis threshold is determined based on the target energy consumption and the preset energy consumption coefficient;
[0079] When the energy consumption per unit mileage is greater than the energy consumption analysis threshold, the target vehicle is determined to meet the preset energy consumption analysis conditions.
[0080] The preset energy consumption coefficient is the same as the preset ratio mentioned above, which can be 120%, and can also be adjusted according to the actual situation. This embodiment does not impose specific restrictions on this.
[0081] Step S40: If satisfied, compare the current energy consumption with the target energy consumption, and execute the corresponding energy consumption analysis strategy based on the comparison result.
[0082] It is understandable that when the vehicle meets the preset energy consumption analysis conditions, comparing the current energy consumption with the target energy consumption means comparing the actual driving energy consumption with the theoretical driving energy consumption, comparing the actual accessory energy consumption with the theoretical accessory energy consumption, and comparing the actual loss energy consumption with the theoretical loss energy consumption.
[0083] It should be noted that energy consumption analysis strategies include, but are not limited to: analyzing whether the current vehicle speed is within a reasonable range, analyzing the frequency and depth of pedal and accelerator pedal operation, analyzing the working status of each accessory, and judging whether there is a risk of high voltage failure. This embodiment does not impose specific limitations on these aspects.
[0084] This embodiment discloses a vehicle energy consumption analysis method. The method includes: upon receiving an energy consumption analysis request, acquiring the vehicle load and current energy consumption of a target vehicle; determining the target energy consumption corresponding to the vehicle load; judging whether the target vehicle meets preset energy consumption analysis conditions based on the current energy consumption and the target energy consumption; if it meets the conditions, comparing the current energy consumption with the target energy consumption, and executing a corresponding energy consumption analysis strategy based on the comparison result. This embodiment determines the target energy consumption corresponding to the vehicle load of the target vehicle and compares the relationship between the current energy consumption and the target energy consumption to determine which energy consumption analysis strategy to execute, matching vehicle energy consumption conditions under various environments, thereby achieving the purpose of vehicle energy consumption monitoring and analysis. This avoids the high cost of monitoring and analyzing energy consumption parameters during vehicle operation in existing technologies and reduces the cost of energy consumption analysis.
[0085] refer to Figure 3 , Figure 3 This is a flowchart illustrating a second embodiment of a vehicle energy consumption analysis method according to the present invention.
[0086] Based on the first embodiment described above, in this embodiment, step S40 includes:
[0087] Step S401: Compare the current driving energy consumption with the target driving energy consumption, the current accessory energy consumption with the target accessory energy consumption, and the current loss energy consumption with the target loss energy consumption.
[0088] It should be noted that the current energy consumption being greater than the target energy consumption does not mean that the corresponding current drive energy consumption, current accessory energy consumption, and current loss energy consumption are all greater than the target drive energy consumption, target accessory energy consumption, and target loss energy consumption. In order to determine the accurate high power consumption condition, the power consumption of each sub-power consumption is compared separately to execute the corresponding energy consumption analysis strategy.
[0089] Step S402: Obtain the energy consumption comparison difference of each energy consumption comparison result.
[0090] Step S403: Determine the maximum value of each energy consumption comparison difference and the corresponding target energy consumption type.
[0091] It is worth noting that determining the maximum value among the differences between each sub-energy consumption comparison, that is, determining the maximum value of the difference between the current driving energy consumption and the target driving energy consumption, the current accessory energy consumption and the target accessory energy consumption, and the current loss energy consumption and the target loss energy consumption, generally takes the energy consumption comparison where the maximum value is located as the target energy consumption type.
[0092] Step S404: Execute the corresponding energy consumption analysis strategy according to the target energy consumption type.
[0093] In specific implementation, the energy consumption analysis strategy includes, but is not limited to: analyzing whether the current vehicle speed is within a reasonable range, analyzing the frequency and depth of pedal and accelerator pedal operation, analyzing the working status of each accessory, and judging whether there is a risk of high voltage failure, etc. This embodiment does not impose specific limitations on these aspects.
[0094] Therefore, it is necessary to develop corresponding analysis strategies based on the specific target energy consumption type.
[0095] Furthermore, the step of executing the corresponding energy consumption analysis strategy based on the target energy consumption type includes:
[0096] When the target energy consumption type is driving energy consumption, the current vehicle speed, pedal pedal frequency and depth information of the target vehicle are obtained;
[0097] Analyze whether the current vehicle speed, the pedaling frequency, and the depth information are within the corresponding preset range;
[0098] If not, then determine the abnormal drive energy consumption parameters and upload them to the vehicle terminal or cloud for display.
[0099] In the specific implementation, if the target energy consumption type corresponding to the maximum value of the energy consumption comparison difference is driving energy consumption, then the impact of driving behavior on power consumption is realized by analyzing whether the current vehicle speed is within a reasonable range and analyzing the frequency and depth of pedal and accelerator pedal pressing. For example, the higher the frequency of pedal and accelerator pedal pressing, the greater the power consumption, and the higher the vehicle speed, the greater the power consumption. The corresponding analysis results will be uploaded to facilitate subsequent vehicle maintenance or after-sales service.
[0100] Furthermore, the step of executing the corresponding energy consumption analysis strategy based on the target energy consumption type includes:
[0101] When the target energy consumption type is accessory energy consumption, obtain the accessory energy consumption of the target vehicle;
[0102] Analyze whether the energy consumption of the accessory is within the corresponding preset range;
[0103] If not, then determine the abnormal accessory energy consumption parameters and upload them to the vehicle terminal or cloud for display.
[0104] It is understandable that if the target energy consumption type corresponding to the maximum value of the energy consumption comparison difference is accessory energy consumption, the main analysis is on the working conditions of each accessory. For example, high-power operation of air conditioning and high-power operation of DC-DC converter may lead to excessive accessory energy consumption. In addition, high-voltage accessories of new energy vehicles are also equipped with EPS (power steering), EAC (brake pump), DC-DC converter and air conditioning (cooling / heating air conditioning). High-voltage accessory analysis can also be performed specifically. This embodiment does not impose specific limitations on this.
[0105] Furthermore, the step of executing the corresponding energy consumption analysis strategy based on the target energy consumption type includes:
[0106] When the target energy consumption type is loss energy consumption, fault information is generated;
[0107] The fault information is uploaded to the vehicle terminal or the cloud for display.
[0108] It is easy to understand that since the energy loss is relatively small compared to the energy consumption of accessories and the driving energy consumption, if the operating conditions of the energy loss are analyzed, it is highly likely that the vehicle has a high-voltage fault. At this time, driving will be risky. Fault information can be generated and the driver can be reminded through instrument and other systems. It can also be reminded to the user through voice or display screen. This embodiment does not make specific limitations in this regard.
[0109] In the specific implementation, refer to Figure 4 , Figure 4 This is a block diagram of the energy consumption analysis structure inside the vehicle according to the present invention. Information such as load, pedal status, frequency, and mileage during the vehicle energy consumption analysis process can be obtained through the corresponding system or structure. The energy consumption of the accessories can be calculated by combining the input working current and working voltage with the working time.
[0110] This embodiment determines the energy consumption of vehicles under various energy consumption analysis conditions by comparing the results of each energy consumption, so as to facilitate subsequent vehicle maintenance or vehicle upgrades, thereby reducing the workload and operating costs of vehicle manufacturers.
[0111] Furthermore, this embodiment of the invention also proposes a storage medium storing a vehicle energy consumption analysis program, which, when executed by a processor, implements the steps of the vehicle energy consumption analysis method described above.
[0112] Since this storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0113] Reference Figure 5 , Figure 5 This is a structural block diagram of the first embodiment of the vehicle energy consumption analysis device of the present invention.
[0114] like Figure 5 As shown, the vehicle energy consumption analysis device proposed in this embodiment of the invention includes:
[0115] The acquisition module 10 is used to acquire the vehicle load and current energy consumption of the target vehicle when it receives an energy consumption analysis request.
[0116] It is understood that the energy consumption analysis request is used to initiate the vehicle energy consumption analysis process. The energy consumption analysis request may be automatically generated by the vehicle controller when the vehicle controller meets the requirements of the energy consumption analysis, or it may be activated by the user or staff by inputting control commands to control the vehicle controller. This embodiment does not impose specific restrictions on this.
[0117] It should be understood that vehicle load capacity includes the sum of the vehicle's own weight and the load weight; current energy consumption refers to the actual energy consumption of the vehicle during operation, including: drive energy consumption, accessory energy consumption, and loss energy consumption, etc. Among them, drive energy consumption refers to the energy consumption of the drive motor during operation, which can be calculated by the input current and voltage of the drive motor and time; accessory energy consumption refers to the sum of the operating energy consumption of each loaded accessory in the vehicle, such as the energy consumption corresponding to accessories such as air conditioning or brake pump; loss energy consumption refers to the energy consumption of electrical energy during transmission.
[0118] Furthermore, the target vehicles in this embodiment are mainly new energy vehicles. Traditional fuel vehicles generate a certain amount of electricity when they are working, which can cause interference when monitoring the energy consumption.
[0119] Furthermore, in order to obtain the accurate current energy consumption of the target vehicle, the vehicle energy consumption analysis method further includes:
[0120] Obtain the basic parameters of the target vehicle, including: the operating power of the drive motor, the power of each accessory, and the power loss;
[0121] Calculate the drive energy consumption within a preset time period based on the operating power;
[0122] Calculate the energy consumption of each accessory within a preset time period based on the power of each accessory;
[0123] The energy loss within a preset time period is calculated based on the power loss.
[0124] In a specific implementation, the basic parameters include the operating power of the drive motor, the power of each accessory, and the power loss. In addition, parameters such as the input and output current and voltage of the drive motor and the input current and voltage of each accessory may also be included. This embodiment does not impose specific limitations on these parameters.
[0125] The query module 20 is used to determine the target energy consumption corresponding to the vehicle's load.
[0126] It is worth noting that target energy consumption refers to the theoretical energy consumption of the target vehicle under vehicle load, including: theoretical driving energy consumption, theoretical accessory energy consumption, and theoretical loss energy consumption, etc.
[0127] In practice, for the same vehicle model, each load range corresponds to a theoretical energy consumption. The correspondence can be obtained by pre-collecting changes in load, speed, mileage, battery pack output and input current, and voltage during the vehicle's operation. Finally, a vehicle load-average energy consumption (WP) table is generated based on the correspondence between the vehicle load and the vehicle's theoretical energy consumption. This table is used to query the target energy consumption corresponding to the vehicle load in energy consumption monitoring.
[0128] The judgment module 30 is used to determine whether the target vehicle meets the preset energy consumption analysis conditions based on the current energy consumption and the target energy consumption.
[0129] It should be noted that the preset energy consumption analysis condition refers to the target vehicle reaching the high energy consumption mileage in two consecutive unit mileages. The high energy consumption mileage means that the actual energy consumption of the vehicle is greater than the theoretical energy consumption of the vehicle, and the ratio of actual energy consumption to theoretical energy consumption is greater than the preset ratio. The preset ratio can be set to 20%, and this embodiment does not impose specific restrictions on it.
[0130] In addition, the unit mileage is used to measure the vehicle's mileage. It can be 100 kilometers or other mileage data. This embodiment does not impose any specific restrictions on this.
[0131] In practice, when the actual energy consumption of a vehicle is detected to be greater than the theoretical energy consumption by more than 20% within two consecutive 100-kilometer intervals, the target vehicle is determined to meet the preset energy consumption analysis conditions.
[0132] Further, the step of determining whether the target vehicle meets the preset energy consumption analysis conditions based on the current energy consumption and the target energy consumption includes:
[0133] Obtain the energy consumption per unit mileage within at least two consecutive unit mileages;
[0134] The energy consumption analysis threshold is determined based on the target energy consumption and the preset energy consumption coefficient;
[0135] When the energy consumption per unit mileage is greater than the energy consumption analysis threshold, the target vehicle is determined to meet the preset energy consumption analysis conditions.
[0136] The preset energy consumption coefficient is the same as the preset ratio mentioned above, which can be 120%, and can also be adjusted according to the actual situation. This embodiment does not impose specific restrictions on this.
[0137] The analysis module 40 is used to compare the current energy consumption with the target energy consumption if the conditions are met, and to execute the corresponding energy consumption analysis strategy based on the comparison result.
[0138] It is understandable that when the vehicle meets the preset energy consumption analysis conditions, comparing the current energy consumption with the target energy consumption means comparing the actual driving energy consumption with the theoretical driving energy consumption, comparing the actual accessory energy consumption with the theoretical accessory energy consumption, and comparing the actual loss energy consumption with the theoretical loss energy consumption.
[0139] It should be noted that energy consumption analysis strategies include, but are not limited to: analyzing whether the current vehicle speed is within a reasonable range, analyzing the frequency and depth of pedal and accelerator pedal operation, analyzing the working status of each accessory, and judging whether there is a risk of high voltage failure. This embodiment does not impose specific limitations on these aspects.
[0140] Furthermore, the judgment module 30 is also used to obtain the current unit mileage energy consumption within at least two consecutive unit mileages; determine the energy consumption analysis threshold based on the target energy consumption and the preset energy consumption coefficient; and determine that the target vehicle meets the preset energy consumption analysis conditions when the current unit mileage energy consumption is greater than the energy consumption analysis threshold.
[0141] Furthermore, the analysis module 40 is also used to compare the current driving energy consumption with the target driving energy consumption, the current accessory energy consumption with the target accessory energy consumption, and the current loss energy consumption with the target loss energy consumption; obtain the energy consumption comparison difference of each energy consumption comparison result; determine the maximum value of each energy consumption comparison difference and the corresponding target energy consumption type; and execute the corresponding energy consumption analysis strategy according to the target energy consumption type.
[0142] Furthermore, the analysis module 40 is also used to acquire the current vehicle speed, pedal cadence and depth information of the target vehicle when the target energy consumption type is driving energy consumption; analyze whether the current vehicle speed, the pedal cadence and the depth information are within the corresponding preset range; if not, determine the abnormal driving energy consumption parameters and upload the abnormal driving energy consumption parameters to the vehicle terminal or cloud for display.
[0143] Furthermore, the analysis module 40 is also used to obtain the accessory energy consumption of the target vehicle when the target energy consumption type is accessory energy consumption; analyze whether the accessory energy consumption is within the corresponding preset range; if not, determine the abnormal accessory energy consumption parameters, and upload the abnormal accessory energy consumption parameters to the vehicle terminal or cloud for display.
[0144] Furthermore, the analysis module 40 is also used to generate fault information when the target energy consumption type is loss energy consumption; and to upload the fault information to the vehicle terminal or the cloud for display.
[0145] Furthermore, the acquisition module 10 is also used to acquire the basic parameters of the target vehicle, including: the operating power of the drive motor, the power of each accessory, and the power loss; calculate the drive energy consumption within a preset time period based on the operating power; calculate the accessory energy consumption within a preset time period based on the power of each accessory; and calculate the power loss energy consumption within a preset time period.
[0146] This embodiment discloses a vehicle energy consumption analysis method. The method includes: upon receiving an energy consumption analysis request, acquiring the vehicle load and current energy consumption of a target vehicle; determining the target energy consumption corresponding to the vehicle load; judging whether the target vehicle meets preset energy consumption analysis conditions based on the current energy consumption and the target energy consumption; if it meets the conditions, comparing the current energy consumption with the target energy consumption, and executing a corresponding energy consumption analysis strategy based on the comparison result.
