Description

Methods, devices, storage media, and electronic equipment for displaying energy consumption in hybrid vehicles Technical Field

[0001] This disclosure relates to the technical field of energy consumption control for hybrid vehicles, and more specifically to an energy consumption display method, device, storage medium, and electronic device for hybrid vehicles. Background Technology

[0002] New energy hybrid vehicles combine good power and economy, meeting national policies and fuel consumption regulations, and are increasingly being promoted and developed by automakers. Hybrid vehicles obtain power from at least two energy sources: the engine consumes fuel, and the electric motor consumes electricity. The resulting electricity consumption is crucial for vehicle energy management. To more rationally manage vehicle energy and effectively calculate the electricity consumption of hybrid vehicles, including instantaneous and average consumption, a comprehensive consideration of multiple factors is necessary. This is because electricity consumption calculation is related to battery output parameters, including battery voltage, current, power, and electrical energy, as well as vehicle speed and mileage. Ineffective calculation of vehicle electricity consumption will inevitably affect vehicle energy management, further impacting the driver's driving experience. Therefore, accurately and effectively calculating vehicle energy consumption is one of the key issues that needs to be addressed.

[0003] Hybrid vehicles have additional components such as drive motors, power batteries, on-board chargers, and DC-DC converters. The method for calculating their electricity consumption is different from that for traditional vehicles. The traditional method for calculating fuel consumption cannot be used directly, and the method for calculating the vehicle's electricity consumption needs to be redesigned.

Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely to serve as the basis and representative basis for the claims to teach those skilled in the art to use this disclosure in a variety of substantially any suitable detailed structures.

[0052] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this disclosure.

[0053] The first embodiment of this disclosure provides a method for displaying energy consumption for hybrid vehicles. It is mainly aimed at hybrid vehicles. As shown in FIG1, the hybrid vehicle includes components such as an engine 10, a drive motor 20, a power battery 30, a gearbox 40, a clutch 50, and a transmission device, as well as a controller corresponding to each component.

[0054] The controllers mentioned here include engine controller (EMS, Engine Management System), vehicle controller (HCU, Hybrid Control Unit), drive motor controller (MCU, Motor Control Unit), battery management system (BMS, Battery Management System), transmission controller (TCU, Transmission Control Unit), DC-DC converter (DCDC, Direct Current Converter), instrument cluster controller (IC, Instrument Cluster), etc.

[0055] The controllers described above communicate with each other via a Controller Area Network (CAN). The vehicle controller is the core controller of the vehicle and is used to coordinate and control other subsystems. The engine controller controls the engine 10, the drive motor controller controls the drive motor 20, the battery management system controls the power battery 30, the transmission controller controls the transmission 40, the DC-DC converter is used to realize DC-DC conversion, and the instrument display controller is used to display various system information, including the instantaneous and average power consumption of the hybrid vehicle.

[0056] As shown in Figure 2, the energy consumption display method for hybrid vehicles according to embodiments of this disclosure includes:

[0057] S101, Obtain the driving parameters of the hybrid vehicle;

[0058] S102, Based on the driving parameters, determine the instantaneous power consumption and the expected average power consumption of the hybrid vehicle, wherein the instantaneous power consumption includes a first instantaneous power consumption and / or a second instantaneous power consumption, wherein the first instantaneous power consumption is the power consumption per 100 kilometers and the second instantaneous power consumption is the power consumption per hour;

[0059] S103, control the display of the first instantaneous power consumption and / or the second instantaneous power consumption and the actual average power consumption, wherein the actual average power consumption is determined based on the expected average power consumption.

[0060] In this embodiment, in step S101 above, driving parameters for calculating instantaneous power consumption and average power consumption are obtained by sensors on the hybrid vehicle. These driving parameters may be, for example, vehicle speed, or parameters of the power battery 30, such as battery bus voltage, battery bus current, and SOC state of charge.

[0061] Step S102 in this embodiment involves calculating instantaneous power consumption and average power consumption. These instantaneous and average power consumption figures can support the energy management status analysis of the hybrid vehicle and further optimize its energy management control functions. The vehicle controller is responsible for calculating instantaneous and average power consumption. Other controllers send relevant signals to the vehicle controller, which then calculates the power consumption and sends the result to the vehicle's instrument panel for display.

[0062] Specifically, in this embodiment, for instantaneous power consumption calculation, the vehicle controller can use two calculation modules to simultaneously calculate instantaneous power consumption in two ways, such as power consumption per 100 kilometers as the first instantaneous power consumption and power consumption per hour as the second instantaneous power consumption.

[0063] Further, determining the instantaneous energy consumption of the hybrid vehicle based on the driving parameters includes:

[0064] When the speed of the hybrid vehicle is greater than or equal to a preset value, a first instantaneous power consumption is determined based on the vehicle speed and battery parameters; when the speed of the hybrid vehicle is less than the preset value, the first instantaneous power consumption is set as a default value; and / or a second instantaneous power consumption is determined based on battery parameters.

[0065] Specifically, the calculation of the first instantaneous power consumption per 100 kilometers is performed by the vehicle controller, which calculates the electrical energy (kWh) consumed when driving 100km under the current operating conditions as the first instantaneous power consumption. The unit of the first instantaneous power consumption is kWh / 100km.

[0066] Specifically: When the vehicle speed is greater than or equal to the preset value, the calculation method for the first instantaneous power consumption P1 is as follows:

[0067] That is, when Vspd≥CAL_Spd, P1={[K1*(BattVol*BattCrt)] / (10*Vspd)}+offset1; where P1 is the first instantaneous power consumption, in kWh / 100km; K1 is the calibration coefficient, which is the instantaneous power calibration coefficient based on vehicle speed; BattVol is the battery bus voltage, in V; BattCrt is the battery bus current, in A; Vspd is the real-time vehicle speed, in km / h; CAL_Spd is the calibration speed as a preset value (e.g., 3km / h); offset1 is the instantaneous power consumption correction value, which can be determined by calibration.

[0068] When the vehicle speed is less than the preset value, the calculation method for the first instantaneous power consumption P1 is as follows:

[0069] When Vspd < CAL_Spd, P1 = Default_value1, where P1 is the first instantaneous power consumption and Default_value1 is the set value.

[0070] Among them, for the calculation of the hourly power consumption as the second instantaneous power consumption, here the vehicle control unit calculates the electrical energy (kWh) consumed per continuous 1 h according to the current working condition as the second instantaneous power consumption, and the unit of the second instantaneous power consumption is kW. Specifically, the calculation method of the second instantaneous power consumption P2 is as follows:

[0071] P2 = [K2 * (BattVol * BattCrt)] + offset2, where P2 is the second instantaneous power consumption, the unit is kWh, K2 is the calibration coefficient, and this value is the instantaneous power calibration coefficient based on time; BattVol is the battery bus voltage, the unit is V; BattCrt is the battery bus current, the unit is A; offset2 is the instantaneous power consumption correction value, which can be determined by calibration.

[0072] After the above-mentioned first instantaneous power consumption and the second instantaneous power consumption are calculated by the vehicle control unit, they are sent to the vehicle instrument for display through the CAN network. Any one or both of the instantaneous power consumption values can be displayed on the instrument, which is convenient for the driver to more intuitively obtain the current vehicle energy consumption situation.

[0073] In addition, a calibratable quantity Flag can be set inside the vehicle control unit as a preset value. When the vehicle speed is less than CAL_Spd (for example, 3 km / h), the first instantaneous power consumption P1 can be numerically equal to the second instantaneous power consumption P2, that is, P1 = P2 at this time.

[0074] Furthermore, when calculating the instantaneous power consumption, signal transmission is carried out between the vehicle control unit and other control units to implement the above-mentioned calculation of the instantaneous power consumption. As shown in Table 1 below, the signals here include four types, HCU input signal, HCU output signal, HCU internal variable, and HCU internal calibratable quantity.

[0075] The HCU input signal here is the signal input to the HCU by other control units, which is used to support the HCU to calculate the instantaneous power consumption; the HCU output signal is the signal output to the instrument control unit by the HCU after calculating the power consumption to display the instantaneous power consumption through the instrument; the HCU internal variable is the internal variable set by the HCU after receiving the input signal from other control units and through internal conversion or calculation as needed; the HCU internal calibratable quantity is some calibratable quantity preset values set by the HCU for calculating the power consumption, and it can be adjusted adaptively.

[0076] Table 1 Instantaneous Power Consumption Calculation Signal Table

[0077] Furthermore, determining the instantaneous energy consumption of the hybrid vehicle based on the driving parameters further includes:

[0078] When the hybrid vehicle is in hybrid drive mode, the first average energy consumption for the entire mileage is determined by the following formula (1):

[0079] Where U and I are the real-time voltage and current of the battery, respectively;

[0080] When the hybrid vehicle is in pure electric drive mode, the second average energy consumption in pure electric mode is determined by the following formula (2):

[0081] This embodiment relates to average energy consumption algorithms under different conditions, where average energy consumption = cumulative energy consumption / cumulative mileage, in kWh / 100km. Considering the special characteristics of hybrid vehicles compared to traditional vehicle powertrains, there are the following two methods for calculating average energy consumption:

[0082] 1) First average energy consumption over the entire mileage:

[0083] 2) Second average energy consumption in pure electric mode:

[0084] Based on the two different calculation methods mentioned above, a separate calculation module within the HCU calculates the first average energy consumption E1 over the entire mileage; a separate calculation module within the HCU also calculates the second average energy consumption E2 in pure electric mode. Here, pure electric mode refers to the operating condition where the engine is not running, and this can be set by the HCU through calibration. If the hybrid vehicle starts its engine during the trip, the calculation follows the method described in the hybrid drive mode; if the engine is not started, the calculation follows the method described in the pure electric mode.

[0085] Furthermore, the calculation of average power consumption can be corrected by incorporating relative deviations, including:

[0086] Determine the third average power consumption based on SOC calibration;

[0087] The relative deviation between the first average energy consumption for the entire mileage and the second average energy consumption in pure electric mode is determined based on the third average energy consumption calibrated by SOC.

[0088] The expected average energy consumption of the hybrid vehicle is determined based on the relative deviation.

[0089] Specifically, it also includes:

[0090] Determine a first deviation value based on the first average power consumption over the entire mileage and the third average power consumption calibrated based on the SOC;

[0091] Determine a second deviation value based on the second average power consumption in the pure electric mode and the third average power consumption calibrated based on the SOC;

[0092] When the first deviation value is less than the second deviation value, determine the first average power consumption over the entire mileage as the predicted average power consumption;

[0093] When the first deviation value is greater than or equal to the second deviation value, determine the second average power consumption in the pure electric mode as the predicted average power consumption.

[0094] Specifically, for the above two calculation methods of average power consumption, the calculation of the average power consumption deviation can also be achieved. For example, first determine the third average power consumption E3 calibrated based on the SOC. Here, E3 is the average power consumption calibrated based on the SOC, with the unit of kWh / 100km, where E3 = [(K3 * △SOC) / cumulative mileage] * 100; △SOC = SOC1 - SOC2.

[0095] Here, K3 is a calibrated value related to the degree of the power battery 30 on the hybrid vehicle. For example, if the battery degree of the hybrid vehicle is 21 kWh, then K3 = 21 kWh; SOC1 is the starting power when calculating the average power consumption, and SOC2 is the ending power.

[0096] Furthermore, determine the corresponding deviation values based on the third average power consumption calibrated based on the SOC. For example, the first deviation value Q1 = [(E1 - E3) / E3] * 100%; the second deviation value Q2 = [(E2 - E3) / E3] * 100%. In this way, a dedicated calculation module can be set in the HCU to calculate the predicted average power consumption E4 within the entire mileage range. Among them, when Q1 < Q2, the actual average power consumption E4 = E1; when Q1 ≥ Q2, the actual average power consumption E4 = E2.

[0097] Furthermore, when calculating the average power consumption, there is signal transmission between the vehicle control unit and other control units to implement the above average power consumption calculation method, as shown in Table 2 below. Here, the signals include four types: HCU input signal, HCU output signal, HCU internal variable, and HCU internal calibrated quantity.

[0098] HCU input signals are signals input from other controllers to the HCU, used to support the HCU in calculating power consumption; HCU output signals are signals output by the HCU after calculating power consumption to the instrument controller so that the average power consumption can be displayed on the instrument; HCU internal variables are internal variables that the HCU receives input signals from other controllers and sets internally for conversion or calculation as needed; HCU internal calibration values ​​are preset values ​​of calibration values ​​set by the HCU for calculating power consumption, which can be adjusted adaptively.

[0099] Table 2 Average Power Consumption Calculation Signal Table

[0100] After obtaining the expected average power consumption E4 through the above method, the actual average power consumption can also be displayed, which includes: obtaining the default average power consumption; determining the actual average power consumption based on the default average power consumption and the corresponding first weight value, as well as the expected average power consumption and the corresponding second weight value.

[0101] Specifically, the display rules here include, for example:

[0102] (1) Updated every 1 second or 30 meters (whichever comes first);

[0103] (2) After a Reset, the accumulated battery level and accumulated mileage are reset to zero;

[0104] (3) After each Reset, for example, within 300 meters (which can be calibrated), "-" is displayed. After 300 meters, the default average energy consumption E5 (or the average energy consumption announced by the vehicle) is displayed, and within, for example, 7 minutes (which can be calibrated), it gradually changes from the default value to the actual value. The change process is as follows:

[0105] The actual average energy consumption E6 is determined using the following formula: E6 = E5 * f1 + E4 * f2, where f1 is the weight of the default average energy consumption, linearly varying from 100% to 0; f2 is the weight of the expected average energy consumption, linearly varying from 0 to 100%, and f1 + f2 = 1. The final actual average energy consumption value E6 is displayed on the vehicle's instrument panel and rounded to one decimal place.

[0106] Furthermore, a filtering algorithm can be used when calculating instantaneous and average power consumption. Specifically, in the above calculation process, to prevent sudden changes in battery discharge power and vehicle speed, filtering is required to remove spikes and make the values ​​continuous and smooth. A first-order filter is added to the algorithm to filter the parameters. The first-order filtering algorithm is as follows:

[0107] Filtered result value = a * current sampled value + (1-a) * previous filtered result value, where a is a number between 0 and 1; thus, the filtered result value of the battery discharge power after the filtering algorithm is:

[0108] P_result=a*new_value1+(1-a)*old_value1;

[0109] This can be understood as follows: Discharge power = BattVol * BattCrt = P_result;

[0110] The result of the vehicle speed filtering algorithm is:

[0111] V_result=a*new_value2+(1-a)*old_value2;

[0112] This can be understood as: vehicle speed = Vspd = V_result.

[0113] In one specific implementation, as shown in Figure 3, when calculating instantaneous power consumption, two calculation modules, namely calculation module one and calculation module two, are set inside the vehicle controller. Calculation module one is used to calculate power consumption per 100 kilometers, and calculation module two is used to calculate power consumption per hour.

[0114] The specific steps are as follows:

[0115] (1) Call the calculation module to calculate the power consumption per 100 kilometers;

[0116] (2) Determine if the vehicle speed is greater than or equal to the preset value. If it is greater than the first preset value, proceed to submodule A to calculate the first instantaneous power consumption P1.

[0117] (3) If the vehicle speed is less than the preset value, then enter submodule B to calculate the first instantaneous power consumption P1;

[0118] (4) Call "Calculation Module 2" to calculate hourly power consumption;

[0119] (5) In the calculation module 2, enter sub-module C and enter the calculation of the second instantaneous power consumption P2.

[0120] In another specific implementation, as shown in Figure 4, when calculating the average energy consumption, three calculation modules are set inside the vehicle controller: calculation module three, calculation module four, and calculation module five. Calculation module three is used to calculate the average energy consumption over the entire range, calculation module four is used to calculate the average energy consumption in pure electric mode, and calculation module five is used to calculate the average energy consumption based on the SOC calibration.

[0121] The specific steps are as follows:

[0122] (1) Call the average power consumption calculation module to determine whether the engine is started;

[0123] (2) If the engine has started, call “Calculation Module 3” to calculate the average power consumption E1 over the entire range;

[0124] (3) If the engine is not started, call "Calculation Module 4" to calculate the average power consumption E2 in pure electric mode;

[0125] (4) Call “Calculation Module 5” to perform the calculation of average power consumption E3 based on SOC calibration;

[0126] (5) Calculate the deviation Q1 based on E1 and E3;

[0127] (6) Calculate the deviation Q2 based on E2 and E3;

[0128] (7) Determine whether Q1 is greater than Q2. When Q1 is greater than or equal to Q2, the actual average power consumption E4 = E2.

[0129] (8) Determine whether Q1 is greater than Q2. When Q1 is greater than Q2, the actual average power consumption E4 = E1.

[0130] (9) Further, the average power consumption E6 is calculated and displayed according to the calculation formula.

[0131] This disclosed embodiment is based on a hybrid vehicle powertrain system. From an energy management perspective, it determines instantaneous and average energy consumption using different methods. In the instantaneous energy consumption calculation, factors such as battery voltage, current, power, and coefficient calibration are considered. In the average energy consumption calculation, different cases are considered, including the entire driving range and pure electric mode. Factors such as battery voltage, current, energy, and SOC are considered, and a deviation coefficient is taken into account for comprehensive calculation. Ultimately, the calculation results of vehicle energy consumption are more reliable and accurate, which can significantly improve the driver's intuitiveness and experience when driving the vehicle.

[0132] Based on the same inventive concept as the first embodiment described above, the second embodiment of this disclosure provides an energy consumption display device for hybrid vehicles, including an acquisition module, a determination module, and a display control module coupled together, wherein:

[0133] The acquisition module is used to acquire the driving parameters of the hybrid vehicle;

The instantaneous power consumption includes a first instantaneous power consumption and / or a second instantaneous power consumption, wherein the first instantaneous power consumption is the power consumption per 100 kilometers and the second instantaneous power consumption is the power consumption per hour.

[0138] Furthermore, when the speed of the hybrid vehicle is greater than or equal to a preset value, the first instantaneous power consumption is determined based on the vehicle speed and battery parameters using the following formula:

[0139] P1 = {[K1*(BattVol*BattCrt)] / (10*Vspd)} + offset1, where P1 is the first instantaneous power consumption, K1 is the instantaneous power calibration coefficient based on vehicle speed; BattVol is the battery bus voltage; BattCrt is the battery bus current; Vspd is the real-time vehicle speed; offset1 is the instantaneous power consumption correction value, which is determined through calibration; and / or

[0140] In determining the second instantaneous power consumption based on battery parameters, the second instantaneous power consumption is determined by the following formula:

[0141] P2 = [K2*(BattVol*BattCrt)] + offset2, where P2 is the second instantaneous power consumption, K2 is the time-based instantaneous power calibration coefficient, BattVol is the battery bus voltage, BattCrt is the battery bus current, and offset2 is the instantaneous power consumption correction value, which is determined by the calibration method.

[0142] Furthermore, the determining module also includes:

[0143] The third determining unit is configured to determine the first average energy consumption over the entire mileage using the following formula when the hybrid vehicle is in hybrid drive mode:
