This application provides a vehicle energy consumption calculation trigger control method, device, system, and vehicle. In response to vehicle power-on, if the current gear is switched to the target gear for the first time, the moment when the current vehicle speed changes to be greater than or equal to a preset target speed is determined as the energy consumption calculation trigger moment. If a trip odometer reset request is received, the trip odometer reset request and the moment when the current vehicle speed changes to be greater than or equal to the preset target speed are used to determine the trip odometer calculation trigger moment. Energy consumption calculation trigger control is performed based on the current energy consumption calculation trigger moment and the trip odometer reset request. This application determines the current energy consumption calculation trigger moment by using the current gear and current vehicle speed, and dynamically determines the trip odometer calculation trigger moment by combining the trip odometer reset request and vehicle speed change conditions. This avoids ignoring the actual operating conditions of the vehicle, which could lead to inaccurate energy consumption statistics, and improves the accuracy and reliability of energy consumption calculation.

Description

Technical Field

[0001] This application relates to the field of vehicle energy consumption control, and in particular to a vehicle energy consumption calculation trigger control method, device, system and vehicle. Background Technology

[0002] With the increasing popularity of electric vehicles, their energy consumption economy has become a core indicator of user concern. For example, the average energy consumption information of electric vehicles is usually displayed intuitively on the dashboard or central control screen, providing drivers with real-time energy consumption feedback, which helps them to adjust their driving behavior in a timely manner, improve energy utilization efficiency and vehicle range. The average energy consumption can be divided into multiple stages based on the driving mileage, such as the average energy consumption of the current mileage and the average energy consumption of the trip mileage. The average energy consumption of the current mileage represents the energy consumption level within a single driving cycle, while the average energy consumption of the trip mileage supports users to calculate energy consumption across custom statistical intervals for different cycles.

[0003] Traditional vehicle energy consumption calculation methods are usually based on simple power-on triggers or fixed time intervals for energy consumption statistics, which often fail to accurately reflect the real energy consumption level in actual driving cycles. Especially in the initial stage after vehicle startup, data changes caused by the activation of various functions can affect the energy consumption calculation data, resulting in the final average energy consumption data including inefficient energy consumption ranges, leading to bias in the data calculation process. In addition, the existing methods' support for the subtotal energy consumption function cannot determine a more accurate energy consumption calculation trigger time based on the actual vehicle status when initiating a reset request, further limiting the reliability and accuracy of the energy consumption calculation values. Summary of the Invention

[0004] The purpose of this application is to provide a vehicle power consumption calculation trigger control method, device, system, and vehicle to solve the above-mentioned technical problems.

[0006] In one embodiment of this application, determining the calculation trigger time for trip meter power consumption based on the issuance time of the trip meter power consumption reset request and the time when the current vehicle speed changes to be greater than or equal to a preset target vehicle speed includes: if the issuance time of the trip meter power consumption reset request is before the time when the current vehicle speed changes to be greater than or equal to the preset target vehicle speed, then the time when the current vehicle speed changes to be greater than or equal to the preset target vehicle speed is determined as the calculation trigger time for trip meter power consumption; if the issuance time of the trip meter power consumption reset request is on or after the time when the current vehicle speed changes to be greater than or equal to the preset target vehicle speed, then the issuance time of the trip meter power consumption reset request is determined as the calculation trigger time for trip meter power consumption.

[0007] In one embodiment of this application, the power consumption calculation trigger control based on the calculation trigger time of the current power consumption and the calculation trigger time of the total power consumption includes: if both the calculation trigger time of the current power consumption and the calculation trigger time of the total power consumption are the moment when the current vehicle speed changes to be greater than or equal to a preset target vehicle speed, then the vehicle controller is made to trigger the calculation of the current power consumption and the calculation of the total power consumption simultaneously when the current vehicle speed changes to be greater than or equal to the preset target vehicle speed, so that the start time of the calculation of the current power consumption and the total power consumption is consistent.

[0008] In one embodiment of this application, determining the calculation trigger time of the trip meter power consumption based on the time when the trip meter power consumption reset request was issued and the time when the current vehicle speed changes to be greater than or equal to the preset target vehicle speed further includes: if the time when the trip meter power consumption reset request was issued was before the last time the vehicle was powered off, and the calculation of the trip meter power consumption was not triggered, then the time when the current vehicle speed changes to be greater than or equal to the preset target vehicle speed is determined as the calculation trigger time of the trip meter power consumption.

[0009] In one embodiment of this application, after power consumption calculation trigger control is performed based on the calculation trigger time of the current power consumption and the calculation trigger time of the trip meter power consumption, the vehicle power consumption calculation trigger control method further includes: if a new trip meter power consumption reset request is received during vehicle operation, and the current vehicle speed is greater than or equal to a preset target vehicle speed, the trip meter power consumption is recalculated based on the time when the new trip meter power consumption reset request is issued; if the vehicle is powered off, and no new trip meter power consumption reset request is received during vehicle operation, the calculation of the current power consumption is exited and the calculation data of the current power consumption is stored, and the calculation of the trip meter power consumption is paused until the next time the vehicle is powered on, the calculation of the trip meter power consumption is resumed starting from the time of power-on.

[0010] In one embodiment of this application, before the recalculation of the trip meter consumption is triggered based on the issuance time of the new trip meter consumption reset request, the vehicle energy consumption calculation trigger control method further includes: storing the current trip meter consumption calculation data, visualizing the trip meter consumption calculation data and sending it to a terminal, wherein the terminal includes a central control terminal and a mobile terminal.

[0011] In one embodiment of this application, the vehicle power consumption calculation trigger control method further includes: setting a current power consumption calculation flag and a trip calculus power consumption calculation flag in the vehicle controller. The current power consumption calculation flag is used to exit the current power consumption calculation when the vehicle is powered off, and to re-lock and trigger the current power consumption calculation when the vehicle is powered on again, if the current gear is switched to the target gear for the first time, and the current vehicle speed changes to be greater than or equal to a preset target vehicle speed. The trip calculus power consumption calculation flag is used to pause the trip calculus power consumption calculation when the vehicle is powered off, and to resume the trip calculus power consumption calculation starting from the time of power-on when the vehicle is powered on again. In addition, when a new trip calculus power consumption reset request is received and the current vehicle speed is greater than or equal to a preset target vehicle speed, the trip calculus power consumption is recalculated based on the time when the new trip calculus power consumption reset request is issued.

[0012] This application embodiment also provides a vehicle energy consumption calculation trigger control device, which includes: an energy consumption trigger monitoring module, used to monitor the vehicle's current gear and current speed in response to vehicle power-on; an energy consumption calculation trigger module, used to trigger a reset of the current energy consumption if the current gear is switched to a target gear for the first time, and to determine the moment when the current speed changes to be greater than or equal to a preset target speed as the calculation trigger moment of the current energy consumption, wherein the current energy consumption represents the average energy consumption within the current power-on driving cycle; if a trip wattage energy consumption reset request is received, the time when the trip wattage energy consumption reset request is issued is obtained, and the calculation trigger moment of the trip wattage energy consumption is determined according to the time when the trip wattage energy consumption reset request is issued and the moment when the current speed changes to be greater than or equal to the preset target speed, wherein the trip wattage energy consumption includes the vehicle's average energy consumption within the time interval from the trip wattage energy consumption calculation trigger moment to the time when the next reset request is issued; and an energy consumption calculation management module, used to perform energy consumption calculation trigger control according to the current energy consumption calculation trigger moment and the trip wattage energy consumption calculation trigger moment.

[0013] This application embodiment also provides a vehicle energy consumption calculation trigger control system, including a vehicle controller, a battery management system, an in-vehicle infotainment system, an instrument cluster, an in-vehicle telematics control unit, and a terminal; the vehicle controller responds to vehicle power-on by monitoring the vehicle's current gear and current speed; if the current gear is switched to the target gear for the first time, it triggers a reset of the current energy consumption, and determines the moment when the current speed changes to be greater than or equal to a preset target speed as the calculation trigger moment for the current energy consumption, where the current energy consumption represents the average energy consumption within the current power-on driving cycle; if the vehicle controller receives a trip meter energy consumption reset request sent by the in-vehicle infotainment system, it obtains the sending time of the trip meter energy consumption reset request, and determines the calculation trigger moment for the trip meter energy consumption based on the sending time of the trip meter energy consumption reset request and the moment when the current speed changes to be greater than or equal to the preset target speed, where the trip meter energy consumption includes the calculation trigger moment for the trip meter energy consumption. The vehicle controller calculates the average energy consumption of the vehicle within the time interval from the current energy consumption to the time when the next reset request is issued. Based on the calculation trigger time of the current energy consumption and the calculation trigger time of the trip metric energy consumption, the vehicle controller performs energy consumption calculation trigger control, calculates the average energy consumption of the current energy consumption and trip metric energy consumption based on the battery monitoring information sent by the battery management system, and sends the average energy consumption information of the current energy consumption and trip metric energy consumption to the in-vehicle infotainment system and the in-vehicle telematics control unit. The battery monitoring information is used to calculate the average energy consumption of the current energy consumption or trip metric energy consumption. The in-vehicle infotainment system sends the message information of the average energy consumption of the current energy consumption and trip metric energy consumption to the in-vehicle telematics control unit, and displays the received average energy consumption information of the current energy consumption and trip metric energy consumption through the instrument panel. The in-vehicle telematics control unit synchronizes the received average energy consumption information of the current energy consumption and trip metric energy consumption to the terminal via a wireless network.

[0014] This application also provides a vehicle, including the vehicle energy consumption calculation trigger control system as described above, or including the vehicle energy consumption calculation trigger control device as described above, or executing the vehicle energy consumption calculation trigger control method as described in any of the above embodiments.

[0015] The beneficial effects of this invention are as follows: This application provides a vehicle energy consumption calculation trigger control method, device, system, and vehicle. In response to vehicle power-on, it monitors the vehicle's current gear and current speed. If the current gear shifts to the target gear for the first time, it triggers a reset of the current energy consumption calculation. The moment when the current speed changes to a speed greater than or equal to a preset target speed is determined as the trigger time for this energy consumption calculation. If a trip mileage energy consumption reset request is received, the time when the trip mileage energy consumption reset request was issued is obtained. Based on the time when the trip mileage energy consumption reset request was issued and the current speed changing to a speed greater than or equal to a preset target speed, the calculation is performed. The timing of the target vehicle speed determines the trigger time for calculating trip meter energy consumption. Energy consumption calculation trigger control is performed based on the current energy consumption calculation trigger time and the trip meter energy consumption calculation trigger time. This application monitors vehicle gear shifting and speed compliance status. When the vehicle first shifts to the target gear and the speed reaches the preset value, it triggers the current energy consumption reset. The timing of trip meter energy consumption calculation trigger is dynamically determined by combining the timing of the trip meter energy consumption reset request with the vehicle speed change conditions. This solves the problem of inaccurate energy consumption statistics caused by ignoring the actual operating conditions of the vehicle in traditional methods, and improves the accuracy and reliability of energy consumption calculation.

[0025] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application.

[0026] The term "and / or" used in this application describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the related objects before and after it are in an "or" relationship.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an exemplary system architecture as shown in an exemplary embodiment of this application.

[0028] Reference Figure 1As shown, the system architecture may include a terminal 110 and a vehicle 120. In response to the vehicle 120 being powered on, the system monitors the vehicle's current gear and current speed. If the current gear shifts to the target gear for the first time, a reset of the current energy consumption is triggered. The moment when the current speed changes to be greater than or equal to the preset target speed is determined as the calculation trigger moment for the current energy consumption. If a trip meter energy consumption reset request is received from the terminal 110, the system obtains the sending time of the trip meter energy consumption reset request. Based on the sending time of the trip meter energy consumption reset request and the moment when the current speed changes to be greater than or equal to the preset target speed, the calculation trigger moment for the trip meter energy consumption is determined. Energy consumption calculation trigger control is performed based on the current energy consumption calculation trigger moment and the trip meter energy consumption calculation trigger moment. The aforementioned terminal 110 refers to an interactive interface that receives the user's selection of the trip meter power consumption reset control, and a computing power support terminal device that visualizes the calculated power consumption and trip meter power consumption data. It includes, but is not limited to, a central control terminal and a mobile terminal. The aforementioned central control terminal includes the vehicle's central control display screen and its auxiliary display terminals. The aforementioned mobile terminal includes mobile phones, tablet devices, microcomputers, and cloud virtual machines, etc. The aforementioned vehicle 120 includes at least a vehicle controller, a battery management system, an in-vehicle infotainment system, an instrument panel, and an in-vehicle telematics control unit.

[0029] Indicatively, in response to vehicle 120 powering on, the system monitors the vehicle's current gear and speed. If the current gear shifts to the target gear for the first time, a reset of the current energy consumption is triggered. The moment when the current speed changes to be greater than or equal to the preset target speed is determined as the trigger time for calculating the current energy consumption. If a trip meter energy consumption reset request is received after selection by terminal 110, the time when the trip meter energy consumption reset request was sent is obtained. The trigger time for calculating the trip meter energy consumption is determined based on the time when the trip meter energy consumption reset request was sent and the moment when the current speed changes to be greater than or equal to the preset target speed. Energy consumption calculation trigger control is performed based on the current energy consumption calculation trigger time and the trip meter energy consumption calculation trigger time. This application, by monitoring the vehicle's gear shift and speed compliance status, triggers the current energy consumption reset when the vehicle first shifts to the target gear and the speed reaches the preset value. By dynamically determining the trip meter energy consumption calculation trigger time by combining the time when the trip meter energy consumption reset request was sent and the speed change conditions, it solves the problem of inaccurate energy consumption statistics caused by ignoring the actual operating conditions of the vehicle in traditional methods, and has the advantages of improving the accuracy and reliability of energy consumption calculation.

[0030] Figure 2 This is a flowchart illustrating an exemplary embodiment of the present application of a vehicle energy consumption calculation trigger control method, which can be implemented in... Figure 1 It can be executed in the implementation environment described above, but it can also be implemented in other implementation environments. No specific limitations are imposed on the aforementioned implementation environments here. (See also...) Figure 2As shown, the flowchart of the vehicle energy consumption calculation trigger control method includes at least steps S210 to S240, which are described in detail below:

[0031] In step S210, in response to the vehicle being powered on, the vehicle's current gear and current speed are monitored.

[0032] In one embodiment of this application, when the vehicle is powered on, the current gear and current speed of the vehicle are continuously monitored. The current gear of the vehicle can be determined by a gear sensor and gear selection information, and the current speed can be determined based on the speed data collected in real time by a speed sensor.

[0033] In step S220, if the current gear is switched to the target gear for the first time, the current power consumption is reset, and the moment when the current vehicle speed changes to be greater than or equal to the preset target vehicle speed is determined as the calculation trigger moment for the current power consumption.

[0034] In one embodiment of this application, the aforementioned current power consumption refers to the average power consumption within the current power-on driving cycle, that is, the average power consumption of the vehicle's mileage from the time the user powers on until the power is turned off; the aforementioned target gear refers to the gear of the vehicle's driving state, such as forward gear or reverse gear; the preset target speed refers to the minimum speed threshold for the vehicle to enter an effective driving state, and in some embodiments, the preset target speed can be selected as 1 km / h.

[0035] In step S230, if a trip meter power consumption reset request is received, the time when the trip meter power consumption reset request was sent is obtained, and the calculation trigger time of trip meter power consumption is determined based on the time when the trip meter power consumption reset request was sent and the time when the current vehicle speed changes to be greater than or equal to the preset target vehicle speed.

[0036] In one embodiment of this application, the aforementioned trip meter power consumption includes the vehicle's average power consumption within the time interval from the trip meter power consumption calculation trigger time to the time the next reset request is issued, that is, the average power consumption of the vehicle's mileage traveled from the time the user resets the trip meter mileage until the next trip meter mileage reset; the time the aforementioned trip meter power consumption reset request is issued is the time point when the user actively triggers the power consumption statistics interval reset operation, and the time information is recorded when the request signal is generated and sent through the interactive interface of the vehicle terminal or mobile terminal. Here, trip meter mileage refers to the mileage interval covered by the average power consumption calculation between the time the user actively triggers the request to calculate the average power consumption within the custom mileage interval and the time the user terminates the calculation of the current custom mileage interval and actively issues the next reset request.

[0037] In one embodiment of this application, if the trip meter reset request is issued before the current vehicle speed changes to a speed greater than or equal to a preset target speed, then the moment when the current vehicle speed changes to a speed greater than or equal to the preset target speed is determined as the trip meter calculation trigger moment. In an actual implementation, if the trip meter reset request occurs before the vehicle reaches the preset target speed, the calculation trigger will be delayed until the vehicle speed reaches the preset target speed, thereby eliminating the complex energy consumption stage at the initial stage of vehicle startup and better reflecting the energy consumption level during driving.

[0038] In one embodiment of this application, if the trip meter reset request is issued at or after the current vehicle speed changes to a speed greater than or equal to a preset target speed, then the issuance time of the trip meter reset request is determined as the calculation trigger time for trip meter consumption. In an actual implementation, if the trip meter reset request occurs after the vehicle has met the speed requirement, then the current time of the trip meter reset request is used as the statistical starting point to ensure that the calculation interval aligns with the user's intention. Figure 1 To.

[0039] In one embodiment of this application, the determination of the trip meter calculation trigger time is used to solve the timing matching problem between the trip meter statistical interval and the actual driving state of the vehicle, as well as to solve the data difference caused by the different calculation timing when the trip meter calculation reset and the current energy consumption calculation reset occur one after the other, to avoid the data containing invalid energy consumption intervals, and to ensure that the two remain consistent after the reset by determining the same calculation trigger time when the trip meter calculation reset and the current energy consumption calculation reset occur one after the other.

[0040] In one embodiment of this application, if the trip meter reset request is issued before the last vehicle power-off and the trip meter calculation is not triggered, then the moment when the current vehicle speed changes to be greater than or equal to a preset target speed is determined as the trip meter calculation trigger moment. Here, "before the last vehicle power-off" refers to the last vehicle power-off operation before the current vehicle power-on. "Not triggering trip meter calculation" means that the triggering conditions were not met after the trip meter reset request was issued, resulting in the calculation not being activated. Specifically, this includes determining whether the vehicle speed has reached the preset target speed and whether the gear position is the target gear, thus avoiding interference from invalid reset requests on data statistics. In a practical implementation, if a user issues a trip meter reset request before the end of the previous driving cycle but the calculation trigger condition is not met, and the vehicle is powered off before reaching the preset target speed after the trip meter reset request is issued, the trip meter reset request will be marked as incomplete. After the vehicle is powered on again, if the current vehicle speed is detected to reach or exceed the preset target speed for the first time, that moment will be automatically used as the starting point for trip meter calculation. This ensures that even if the reset request is issued in an invalid state, the calculation can still be reactivated through the valid speed conditions in subsequent driving cycles.

[0041] In step S240, power consumption calculation trigger control is performed based on the calculation trigger time of the current power consumption and the calculation trigger time of the subtotal power consumption.

[0042] In one embodiment of this application, if the trigger time for calculating both the current energy consumption and the trigger time for calculating the trip calculus energy consumption are the moment when the current vehicle speed changes to a speed greater than or equal to a preset target speed, then the vehicle controller simultaneously triggers the calculation of both the current energy consumption and the trip calculus energy consumption at the moment the current vehicle speed changes to a speed greater than or equal to the preset target speed, so that the start times of the current energy consumption and trip calculus energy consumption calculations are consistent. The vehicle controller is the core control unit used to coordinate the vehicle's powertrain system and battery management system, and it synchronously triggers multiple energy consumption calculation tasks through an embedded processor and a pre-configured preset algorithm module.

[0043] In one embodiment of this application, this solution eliminates statistical benchmark deviations and data differences within intervals caused by multiple triggers by identifying the consistency of trigger times and synchronously calculating the starting point.

[0044] In one embodiment of this application, after controlling the power consumption calculation based on the current power consumption calculation trigger time and the trip mileage power consumption calculation trigger time, if a new trip mileage power consumption reset request is received during vehicle operation, and the current vehicle speed is greater than or equal to a preset target speed, the trip mileage power consumption is recalculated based on the time the new trip mileage power consumption reset request was issued. In an actual implementation, when a new trip mileage power consumption reset request is received during vehicle operation, it is first checked whether the current vehicle speed has reached the preset target speed. If the current vehicle speed is greater than or equal to the preset target speed, the trip mileage power consumption data is re-accumulated starting from the time the reset request was issued, avoiding statistical deviations caused by a mismatch between the request trigger time and the vehicle state.

[0045] If the vehicle is powered off and no new trip meter reset request is received during vehicle operation, the calculation of the current trip meter consumption is terminated, the calculated data is stored, and the trip meter consumption calculation is paused until the vehicle is powered on again, resuming calculation from the power-on time. In an actual implementation, if no new trip meter reset request is received before the vehicle is powered off, the accumulated data of the current trip meter consumption is stored in the vehicle's non-volatile memory, and the trip meter consumption statistics thread is paused. Upon the next power-on, the stored data is automatically read and the accumulation resumes from the power-on time, thus maintaining the integrity of the time interval for trip meter consumption statistics.

[0046] This application enables dynamic adjustment of the statistical interval when the user actively resets the trip meter power consumption, while ensuring that the reset operation only takes effect when the vehicle is in active driving condition. In addition, by storing the power consumption data and pausing the calculation after power is off, the continuity and integrity of power consumption statistics across driving cycles are guaranteed, enabling users to obtain more reliable long-term energy consumption analysis data.

[0047] Among them, the new trip meter power consumption reset request refers to the instruction triggered by the user during vehicle operation to recalculate trip meter power consumption. The request and instruction can be generated through buttons on the in-vehicle interactive interface or voice commands. The selection of stored calculation data is implemented through non-volatile memory to ensure data availability. Pausing trip meter power consumption calculation means interrupting the statistical logic during power-off. When it is restored, the calculation can be resumed and continued by using timestamp records, ensuring the continuity of statistics across driving cycles.

[0048] In one embodiment of this application, before the recalculation of the trip meter consumption is triggered by the issuance of a new trip meter consumption reset request, the calculated trip meter consumption data for the current period is stored. This data is then visualized and sent to the terminals, which include a central control terminal and a mobile terminal. Storing the calculated trip meter consumption data involves saving the consumption data for the current statistical period to non-volatile memory. In this embodiment, the data is stored in non-volatile memory using a segmented storage method, marked with timestamps, to avoid data loss due to vehicle power failure. Visualizing and sending the data to the terminal means converting the trip meter consumption data into graphical, trend, statistical, or tabular forms. The processed data can be transmitted in real-time to the central control screen and the user's mobile application via the vehicle communication module, achieving cross-platform data synchronization.

[0049] In one embodiment of this application, a current energy consumption calculation flag and a trip calculus energy consumption calculation flag are set in the vehicle controller. The current energy consumption calculation flag is used to exit the calculation of current energy consumption when the vehicle is powered off, and to re-lock and trigger the calculation of current energy consumption when the vehicle is powered on again, if the current gear is switched to the target gear for the first time, or if the current vehicle speed changes to be greater than or equal to a preset target vehicle speed. The trip calculus energy consumption calculation flag is used to pause the calculation of trip calculus energy consumption when the vehicle is powered off, and to resume the calculation of trip calculus energy consumption from the time the vehicle is powered on again, and to trigger the recalculation of trip calculus energy consumption based on the time when a new trip calculus energy consumption reset request is received and the current vehicle speed is greater than or equal to a preset target vehicle speed.

[0050] The current energy consumption calculation flag or subtotal energy consumption calculation flag refers to a binary variable used to control the average energy consumption calculation status within the current driving cycle. This includes setting and resetting specific bits in a register or memory address to switch the flag. The flag is automatically reset when the vehicle is powered off to terminate the current energy consumption calculation, and is re-set when the gear shift and vehicle speed conditions are met to trigger the calculation.

[0051] This application provides a vehicle energy consumption calculation trigger control method. In response to vehicle power-on, it monitors the vehicle's current gear and speed. If the current gear shifts to the target gear for the first time, it triggers a reset of the current energy consumption. The moment when the current speed changes to be greater than or equal to a preset target speed is determined as the calculation trigger moment for this energy consumption. If a trip metric energy consumption reset request is received, the time when the request was sent is obtained. The calculation trigger moment for trip metric energy consumption is determined based on the time of the request and the moment when the current speed changes to be greater than or equal to the preset target speed. Energy consumption calculation trigger control is performed based on the current energy consumption calculation trigger moment and the trip metric energy consumption calculation trigger moment. This application monitors vehicle gear shifting and speed compliance status, triggering a reset of energy consumption when the vehicle first shifts to the target gear and reaches a preset speed. By dynamically determining the trip metric energy consumption calculation trigger moment by combining the time of the reset request and the speed change conditions, it solves the problem of inaccurate energy consumption statistics caused by ignoring the actual operating conditions of the vehicle in traditional methods, and has the advantages of improving the accuracy and reliability of energy consumption calculation.

[0052] The following describes a system embodiment of this application, which can be used to execute the vehicle energy consumption calculation trigger control method in the above embodiments of this application. For details not disclosed in the system embodiments of this application, please refer to the embodiments of the vehicle energy consumption calculation trigger control method described above. This system can be applied to... Figure 2 The method implementation process shown allows the system to be based on Figure 1 The implementation environment shown can be applied to other exemplary implementation environments and specifically configured in other devices. This embodiment does not limit the implementation environment to which the system is applicable.

[0053] This exemplary vehicle energy consumption calculation trigger control system includes a vehicle controller, a battery management system, an in-vehicle infotainment system, an instrument cluster, an in-vehicle telematics control unit, and a terminal.

[0054] The vehicle controller responds to vehicle power-on by monitoring the vehicle's current gear and current speed. If the current gear shifts to the target gear for the first time, it triggers a reset of the current energy consumption, and determines the moment when the current speed changes to be greater than or equal to a preset target speed as the calculation trigger moment for the current energy consumption. The current energy consumption represents the average energy consumption within the current power-on driving cycle. If the vehicle controller receives a trip meter energy consumption reset request from the in-vehicle infotainment system, it obtains the time when the trip meter energy consumption reset request was sent, and determines the calculation trigger moment for the trip meter energy consumption based on the time when the trip meter energy consumption reset request was sent and the moment when the current speed changes to be greater than or equal to the preset target speed. The trip meter energy consumption includes the vehicle's average energy consumption within the time interval from the trip meter energy consumption calculation trigger moment to the time when the next reset request is sent. The device performs power consumption calculation trigger control based on the calculation trigger time of the current power consumption and the calculation trigger time of the trip power consumption. It calculates the average power consumption of the current power consumption and trip power consumption based on the battery monitoring information sent by the battery management system, and sends this average power consumption information to the in-vehicle infotainment system and the in-vehicle telematics control unit. The battery monitoring information is used to calculate the average power consumption of the current power consumption or trip power consumption.
