This embodiment is applicable to the case of adjusting and displaying data on a vehicle instrument, and is particularly applicable to the case of adjusting and displaying the instantaneous power and power percentage of a vehicle. This method can be executed by a vehicle instrument data adjustment device, which can be implemented in software and / or hardware, and can be integrated into an electronic device with a vehicle instrument data adjustment function, for example, in a vehicle, and executed by a vehicle controller in the vehicle, wherein the vehicle controller can be a vehicle-mounted communication unit (VCU) of the vehicle. Figure 1 As shown, the method includes:

[0031] S101. Determine the initial instantaneous power and initial power percentage of the vehicle at the current moment according to the vehicle model, drive wheel configuration parameters and power component parameters at the current moment.

[0032] The vehicle refers to a vehicle with a power display function, such as a pure electric vehicle and a fuel cell electric vehicle. The vehicle model refers to a vehicle model that can characterize the vehicle's energy supply mode and motor drive mode. The drive wheel configuration parameter refers to a parameter that can characterize the vehicle's drive wheel. For example, a drive wheel configuration parameter of 1 indicates that the vehicle's drive wheel is the vehicle's front wheel, and a drive wheel configuration parameter of 0 indicates that the vehicle's drive wheel is the vehicle's rear wheel.

[0033] The power component parameters refer to the component parameters related to the vehicle power. Specifically, the power component parameters may include the engine output shaft torque T0, the transmission ratio α from the engine output shaft to the wheel, the front drive motor torque T1, the rear drive motor torque T2, the transmission ratio β from the front drive motor output shaft to the wheel, the transmission ratio γ from the rear drive motor output shaft to the wheel, the front drive motor speed n1 and the rear drive motor speed n2. Among them, the engine output shaft torque T0 refers to the torque of the engine acting on the output shaft. The front drive motor torque T1 and the rear drive motor torque T2 refer to the torques of the front and rear drive motors acting on the output shaft, respectively. The front drive motor speed n1 and the rear drive motor speed n2 refer to the absolute values ​​of the corresponding speeds of the front and rear drive motors, respectively.

[0034] Initial instantaneous power refers to the preliminarily determined instantaneous power. Instantaneous power refers to the instantaneous execution power of the vehicle at the wheel end, and the unit is kW. When the instantaneous power is positive, it means that it is consuming energy, and when the instantaneous power is negative, it means that it is recovering energy. The initial power percentage refers to the percentage that represents the ratio of the initial instantaneous power to the maximum driving power.

[0035] Optionally, the vehicle may determine a pre-stored vehicle model identification number, match the identification number, determine the vehicle model associated with the identification number, and directly obtain preset drive wheel configuration parameters from a storage unit of the vehicle.

[0036] Optionally, the vehicle controller can interact with the engine controller and the drive motor controller in real time to obtain the power component parameters at the current moment.

[0037] Optionally, after determining the vehicle model, drive wheel configuration parameters and power component parameters at the current moment, the vehicle model, drive wheel configuration parameters and power component parameters at the current moment can be input into a pre-trained model to directly output the corresponding initial instantaneous power and initial power percentage, that is, determine the initial instantaneous power and initial power percentage of the vehicle at the current moment; or, according to preset calculation rules, when the vehicle model and drive wheel configuration parameters meet preset conditions, substitute the power component parameters at the current moment into the calculation formula to calculate the corresponding initial instantaneous power and initial power percentage, that is, determine the initial instantaneous power and initial power percentage of the vehicle at the current moment.

[0038] S102, determining a target instantaneous power and a target power percentage according to the initial instantaneous power, initial power percentage, filter coefficient, drive system status, communication status, and initial instantaneous power of the vehicle at the previous moment.

[0039] Among them, the filter coefficient refers to the preset coefficient required for filtering processing, which can be expressed by λ. Generally, the value range of the filter coefficient is 0<λ<1. Preferably, the filter coefficient is 0.05<λ<0.2. The drive system state refers to the state that characterizes whether the vehicle drive system is ready, and the drive system state includes the ready state (READY state) and the unready state. The ready state of the drive system refers to the state in which the driver can drive the vehicle or the driver has driven the vehicle. Specifically, at this time, the vehicle has completed the high-voltage power-on of the drive system, and each controller has completed the initialization. The communication state refers to the state that characterizes whether the vehicle controller of the vehicle can communicate normally with the drive motor controller, the engine controller or its own internal module. The communication state can include two communication states: barrier-free and barrier-free. The initial instantaneous power of the vehicle at the last moment refers to the instantaneous power determined by the vehicle at the last moment directly obtained from the storage unit. The target instantaneous power and the target power percentage refer to the instantaneous power and power percentage of the target determined at the current moment, respectively, which are adjusted and displayed.

[0040] Optionally, the state of the drive system can be determined based on the state flag of the drive system. For example, if the state flag of the drive system is in the READY state, the state of the drive system is determined to be in the ready state. If the state flag of the drive system is not in the READY state, the state of the drive system is determined to be in the not ready state.

[0041] Optionally, if the vehicle controller and drive motor controller, the vehicle controller and engine controller of the vehicle can communicate normally, and the modules inside the vehicle controller can also communicate normally, then the communication status is considered to be an unobstructed state, otherwise the communication status is an obstructed state.

[0042] For example, if the vehicle controller detects a communication barrier with the instrument controller, or is in an initialization phase causing the instrument controller to be unable to communicate with the vehicle controller, the communication state can be considered to be a barrier state.

[0043] Optionally, the vehicle's initial instantaneous power, initial power percentage, filter coefficient, drive system status, communication status, and initial instantaneous power of the vehicle at the previous moment can be input into a pre-trained model to directly output the target instantaneous power and target power percentage, that is, to determine the target instantaneous power and target power percentage; or, according to preset rules, when the drive system status and communication status meet preset conditions (such as the drive system status is ready and the communication status is unobstructed), the target instantaneous power and target power percentage can be calculated based on the vehicle's initial instantaneous power at the current moment, initial power percentage, filter coefficient, and the initial instantaneous power of the vehicle at the previous moment, that is, to determine the target instantaneous power and target power percentage.

[0044] Optionally, if the drive system state and the communication state do not meet preset conditions, such as the drive system state is not ready, and / or the communication state is blocked, the target instantaneous power and the target power percentage can be directly determined to be zero.

[0045] S103: Adjust the display data of the vehicle instrument according to the target instantaneous power and the target power percentage.

[0046] The vehicle instrument refers to a functional instrument controller on the vehicle that can be used to display power and power percentage.

[0047] Optionally, after determining the target instantaneous power and target power percentage of the vehicle at the current moment, the display data of the vehicle instrument can be adjusted from the target instantaneous power and target power percentage of the previous moment to the target instantaneous power and target power percentage of the current moment, so that the power pointer points to the corresponding scale, or displays the corresponding target instantaneous power and target power percentage numbers, that is, the display data of the vehicle instrument is adjusted according to the target instantaneous power and target power percentage.

[0048] Optionally, if the drive system status is not ready and / or the communication status is obstructed, after determining that the target instantaneous power and the target power percentage are both zero, the instantaneous power and the power percentage can be placed in the "initial position", that is, the pointer points to the scale 0, or the digital display is 0.

[0049] The technical solution of the embodiment of the present invention determines the initial instantaneous power and initial power percentage of the vehicle at the current moment according to the vehicle model, drive wheel configuration parameters and power component parameters at the current moment, determines the target instantaneous power and target power percentage according to the initial instantaneous power, initial power percentage, filter coefficient, drive system state, communication state and initial instantaneous power of the vehicle at the previous moment, and finally adjusts the display data of the vehicle instrument according to the target instantaneous power and the target power percentage. By determining more accurate instantaneous power for different vehicle models and adjusting the display in time, the driving state of the vehicle can be more realistically reflected, and the driving convenience of the vehicle can be improved.

[0050] Optionally, the target instantaneous power and target power percentage are determined based on the vehicle's initial instantaneous power at the current moment, the initial power percentage, the filtering coefficient, the drive system status, the communication status, and the initial instantaneous power of the vehicle at the previous moment, including: if the drive system status is ready and the communication status is unobstructed, the initial instantaneous power of the vehicle at the current moment is filtered based on the vehicle's initial instantaneous power at the current moment, the vehicle's initial instantaneous power at the previous moment, and the filtering coefficient to determine the target instantaneous power; and the target power percentage is determined based on the initial power percentage.

[0051] Optionally, if the drive system status is ready and the communication status is unobstructed, the initial instantaneous power of the vehicle at the current moment, the initial instantaneous power of the vehicle at the previous moment, and the filter coefficient can be directly input into a pre-trained filter model for filtering, and the target instantaneous power is output, that is, the target instantaneous power is determined; the initial instantaneous power of the vehicle at the current moment, the initial instantaneous power of the vehicle at the previous moment, and the filter coefficient can be substituted into the formula according to the preset calculation rules to calculate the target instantaneous power, that is, to determine the target instantaneous power.

[0052] Exemplarily, the target instantaneous power P(t) may be calculated by the following formula:

[0053] P(t)=p(t-1)+[p(t)-p(t-1)]*λ

[0054] Among them, p(t-1) is the initial instantaneous power of the vehicle at the previous moment, p(t) is the initial instantaneous power of the vehicle at the current moment, and λ is the filter coefficient.

[0055] Embodiment 2

[0056] Figure 2 is a flow chart of a vehicle instrument data adjustment method provided by the present invention. Based on the above embodiments, this embodiment further explains in detail "determining the initial instantaneous power and initial power percentage of the vehicle at the current moment according to the vehicle model, drive wheel configuration parameters and power component parameters at the current moment", such as Figure 2 As shown, the method includes:

[0057] S201. Determine the power calculation parameters of the vehicle according to the vehicle model, drive wheel configuration parameters and power component parameters at the current moment.

[0058] The power calculation parameters include engine wheel torque, drive motor torque and drive wheel speed. Engine wheel torque A refers to the torque output by the engine and acting on the wheel end, drive motor torque B refers to the torque output by the drive motor and acting on the wheel end, and drive wheel speed C refers to the speed of the drive wheel.

[0059] Optionally, the vehicle model, drive wheel configuration parameters and power component parameters at the current moment can be directly input into a pre-trained model to output the engine wheel torque, drive motor torque and drive wheel speed, that is, to determine the vehicle's power calculation parameters; or the vehicle model, drive wheel configuration parameters and power component parameters at the current moment can be analyzed and calculated according to preset rules to obtain the engine wheel torque, drive motor torque and drive wheel speed.

[0061] Optionally, the vehicle model can be determined based on a pre-stored vehicle model identification number, and the vehicle model can be further matched to determine the energy supply mode and drive mode associated with the vehicle model. For example, if the vehicle model is a hybrid model, it can be determined that the vehicle energy supply mode is a hybrid energy supply. If the vehicle model is a dual-drive motor model, it can be determined that the vehicle drive mode is dual-drive. If the vehicle model is a single-drive motor model, it can be determined that the vehicle drive mode is single-drive.

[0062] Optionally, if the vehicle model is other than a hybrid vehicle model, the engine wheel torque can be directly determined to be zero.

[0065] S202: Determine the initial instantaneous power and initial power percentage of the vehicle at the current moment according to the power calculation parameter and the maximum driving power.

[0066] The maximum driving power refers to the maximum driving power that the vehicle can reach, which is a fixed value in kW. The preset maximum driving power is different for different models. Even for the same model, the preset maximum driving power is different for high-end and low-end vehicles.

[0067] It should be noted that, in this embodiment, the maximum driving power is not a simple sum of the peak output powers of each powertrain.

[0068] Optionally, the vehicle may perform comprehensive simulation calculations to obtain the maximum driving power based on one or more of configuration parameters, environmental parameters, vehicle parameters, layout, performance parameters of the powertrain, and conversion efficiency between various levels.

[0069] Optionally, after determining the maximum driving power, the power calculation parameters and the maximum driving power can be input into a pre-trained model to output the initial instantaneous power and the initial power percentage; the power calculation parameters can also be substituted into the calculation formula according to the preset calculation rules to calculate the initial instantaneous power, and the ratio of the initial instantaneous power to the maximum driving power can be further calculated, and the ratio can be used as the initial power percentage, that is, the initial instantaneous power and the initial power percentage of the vehicle at the current moment can be determined.

In this way, a feasible implementation method for determining the initial instantaneous power and the initial power percentage is provided, which facilitates the subsequent determination of a more accurate target instantaneous power and power percentage and timely adjustment of the display, which can more realistically reflect the driving state of the vehicle and improve the convenience of vehicle driving.

Exemplarily, the engine wheel torque A can be determined by the following calculation formula:

[0074] A=T0*α

[0075] Wherein, T0 is the engine output shaft torque, which satisfies T0≥0, and the unit is Nm. α is the transmission ratio from the engine output shaft to the wheel, which satisfies α>0.

[0076] Optionally, the drive motor torque and the drive wheel speed are determined according to the motor drive mode, the drive wheel configuration parameters and the power component parameters, including: if the motor drive mode is dual drive, the drive motor torque and the drive wheel speed are determined according to the power component parameters; if the motor drive mode is single drive, the drive motor torque and the drive wheel speed are determined according to the drive wheel configuration parameters and the power component parameters.

[0077] For example, if the motor driving mode is dual drive, the driving motor torque B can be determined based on the following calculation formula according to the power component parameters:

[0078] B=T1*β+T2*γ

[0079] Among them, T1 is the front drive motor torque, T2 is the rear drive motor torque, β is the transmission ratio from the front drive motor output shaft to the wheel, and γ is the transmission ratio from the rear drive motor output shaft to the wheel.

[0080] For example, if the motor driving mode is dual drive, the driving wheel speed C can be determined based on the following calculation formula according to the power component parameters:

[0081] C=(n1 / β+n2 / γ) / 2

[0082] Among them, β is the transmission ratio from the output shaft of the front drive motor to the wheel, γ is the transmission ratio from the output shaft of the rear drive motor to the wheel, n1 is the speed of the front drive motor, and n2 is the speed of the rear drive motor.

[0083] It should be noted that when the vehicle is moving, the rotation speeds of the front and rear wheels are almost the same, so the algebraic average of the two can be taken to determine the drive wheel speed C.

[0084] Optionally, if the motor drive mode is single drive, it is possible to determine whether the front wheels of the vehicle are drive wheels or the rear wheels of the vehicle are drive wheels based on the drive wheel configuration parameters, and further calculate the power component parameters based on the corresponding calculation rules to determine the drive motor torque and drive wheel speed.

[0085] For example, if the front wheels of the vehicle are driving wheels, the driving motor torque B and the driving wheel speed C can be determined based on the following calculation formulas:

[0086] B=T1*β,C=n1 / β

[0087] Among them, β is the transmission ratio from the output shaft of the front drive motor to the wheel, n1 is the speed of the front drive motor, and T1 is the torque of the front drive motor.

[0088] For example, if the rear wheels of the vehicle are driving wheels, the driving motor torque B and the driving wheel speed C can be determined based on the following calculation formulas:

[0089] B=T2*γ,C=n2 / γ

[0090] Among them, γ is the transmission ratio from the output shaft of the rear drive motor to the wheel, n2 is the speed of the rear drive motor, and T2 is the torque of the rear drive motor.

[0101] Exemplarily, determining the initial power percentage ψ of the vehicle at the current moment may be based on the following formula:

[0102] ψ=p / Pmax

[0103] Where, ψ refers to the initial power percentage, the unit is %, and the value range of ψ is -100% to 100%. Pmax refers to the maximum driving power. p refers to the initial instantaneous power.
