A first embodiment of the present disclosure provides an electricity consumption display method for a hybrid vehicle, which is mainly directed to a hybrid vehicle including components of an engine 10, a driving motor 20, a power battery 30, a transmission 40, a clutch 50, and a transmission, and also having controllers corresponding to the components, as shown in fig. 1.

As shown in fig. 2, an electricity consumption display method for a hybrid vehicle according to an embodiment of the present disclosure includes:
S101, acquiring running parameters of the hybrid vehicle;
S102, determining the instantaneous power consumption and the expected average power consumption of the hybrid vehicle based on the driving parameters, wherein the instantaneous power consumption comprises a first instantaneous power consumption and/or a second instantaneous power consumption, the first instantaneous power consumption is hundred kilometers of power consumption, and the second instantaneous power consumption is hour of power consumption;
s103, controlling and displaying 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 estimated average power consumption.
In the present embodiment, in the step S101, the sensor on the hybrid vehicle acquires the running parameters for calculating the instantaneous power consumption and the average power consumption, where the running parameters may be, for example, the vehicle speed, etc., or may be, for example, parameters of the power battery 30, such as the battery bus voltage, the battery bus current, the SOC state of charge, etc.
The above-described step S102 of the present embodiment relates to calculation of instantaneous electricity consumption and average electricity consumption, which can be used for supporting energy management state analysis of the hybrid vehicle, and which can further optimize energy management control functions of the vehicle. The carrier for realizing calculation of instantaneous power consumption and average power consumption is a whole vehicle controller, other controllers send related signals to the whole vehicle controller, and the whole vehicle controller sends the result to a vehicle instrument for display after calculation.
Specifically, in the present embodiment, for the calculation of the instantaneous power consumption, the calculation of the instantaneous power consumption may be achieved in two ways at the same time by 2 calculation modules inside the vehicle controller, including, for example, hundred kilometers of power consumption as the first instantaneous power consumption and hours of power consumption as the second instantaneous power consumption.
Further, the determining the instantaneous power consumption of the hybrid vehicle based on the running parameter includes:
Determining a first instantaneous power consumption based on a vehicle speed and battery parameters when the vehicle speed of the hybrid vehicle is greater than or equal to a preset value, and determining the first instantaneous power consumption as a default value when the vehicle speed of the hybrid vehicle is less than the preset value; and/or determining a second instantaneous power consumption based on the battery parameter.
For the calculation of hundred km electricity consumption as the first instantaneous electricity consumption, the electric energy (kWh) consumed for running 100km under the current working condition is calculated by the vehicle control unit as the first instantaneous electricity consumption, wherein the first instantaneous electricity consumption unit is kWh/100km.
Specifically: when the vehicle speed is greater than or equal to a preset value, the first instantaneous power consumption P1 calculation method is as follows:
That is, when Vspd is not less than cal_spd, p1= { [ k1+ (BattVol × BattCrt) ]/(10×vspd) } + offset1; wherein P1 is the first instantaneous power consumption, and the unit is kWh/100km; k1 is a calibration coefficient, and the value is an instantaneous power calibration coefficient based on the vehicle speed; battVol is the voltage of a battery bus, and the unit is V; battCrt is the current of a battery bus, and the unit is A; vspd is the real-time vehicle speed, and the unit is km/h; CAL_Spd is a calibrated vehicle speed (for example, 3 km/h) as a preset value; offset1 is an instantaneous power consumption correction value, and can be determined by a calibration mode.
When the vehicle speed is smaller than a preset value, the first instantaneous power consumption P1 is calculated as follows:
When Vspd < cal_spd, p1=default_value1, where P1 is the first instantaneous power consumption and default_value1 is the set value.
For the calculation of the hour power consumption as the second instantaneous power consumption, the vehicle control unit calculates the electric energy (kWh) consumed per 1 hour duration as the second instantaneous power consumption, the second instantaneous power consumption having a power unit of kW. Specifically, the calculation method of the second instantaneous power consumption P2 is as follows:
P2= [ k2+ (BattVol × BattCrt) ] +offset2, wherein P2 is the second instantaneous power consumption, the unit is kWh, K2 is the calibration coefficient, and the value is the instantaneous power calibration coefficient based on time; battVol is the voltage of a battery bus, and the unit is V; battCrt is the current of a battery bus, and the unit is A; offset2 is an instantaneous power consumption correction value, and can be determined by a calibration mode.
The first instantaneous power consumption and the second instantaneous power consumption are calculated by the whole vehicle controller and then sent to the vehicle instrument for display through the CAN network, and any one or two instantaneous power consumption values CAN be displayed on the instrument, so that a driver CAN acquire the current energy consumption condition of the vehicle more intuitively.
Furthermore, a calibratable amount Flag may be set in the whole vehicle controller as a preset value, and when the vehicle speed is smaller than cal_spd (for example, 3 km/h), the first instantaneous power consumption P1 may be equal in value to the second instantaneous power consumption P2, that is, p1=p2 at this time.
Further, when the calculation of the instantaneous power consumption is performed, signal transmission is performed between the vehicle controller and other controllers, so as to implement the calculation of the instantaneous power consumption, as shown in the following table 1, where the signals include four types of HCU input signals, HCU output signals, HCU internal variables, and HCU internal standard amounts.
The HCU input signal is the signal input to the HCU by other controllers and is used for supporting the HCU to calculate the instantaneous power consumption; the HCU output signal, namely, after the HCU calculates the electricity consumption, is output to the instrument controller for displaying the instant electricity consumption through the instrument; the HCU internal variable, namely the HCU receives input signals of other controllers, and the internal variable is set through the internal conversion or calculation of the HCU; the HCU internal standard quantity, i.e. some standard quantity preset value set by the HCU for calculating the electricity consumption, can be adaptively adjusted.
Table 1 instantaneous power consumption calculation signal table
Further, the determining the instantaneous power consumption of the hybrid vehicle based on the running parameter further includes:
when the hybrid vehicle is in a hybrid drive mode, a first average power consumption of a full mileage is determined by the following formula:
; wherein U, I is the real-time voltage and current of the battery, respectively;
When the hybrid vehicle is in the electric-only drive mode, the second average power consumption in the electric-only drive mode is determined by the following formula:
。
The present embodiment relates to an average electricity consumption algorithm for different situations, where average electricity consumption = accumulated consumed electric energy/accumulated mileage in kWh/100km. Considering the specificity of a hybrid electric vehicle relative to a traditional vehicle power system, the following two average power consumption calculation modes are adopted:
1) First average power consumption of full mileage
；
2) Second average power consumption in electric-only mode
；
Based on the two different calculation modes, calculating a first average power consumption E1 in a full mileage range through a separate calculation module in the HCU; the second average electricity consumption E2 in the electric-only mode is calculated inside the HCU by a separate calculation module. The pure electric mode refers to a working condition that the engine is not operated, and the HCU can be set through a standard quantity. If the hybrid vehicle has a condition of starting the engine in the course, it is calculated in the above-described hybrid drive mode, and if the engine is not started at all times, it is calculated in the above-described electric-only mode.
Further, the calculation of the average power consumption may be modified in combination with the relative deviation, including:
determining a third average power consumption based on SOC calibration;
Determining the relative deviation of the first average power consumption of the full mileage and the second average power consumption in the pure electric mode based on the third average power consumption based on the SOC calibration;
an estimated average power consumption of the hybrid vehicle is determined based on the relative deviation.
Specifically, the method further comprises the following steps:
determining a first deviation value based on the first average power consumption of the full mileage and the third average power consumption based on the SOC calibration;
determining a second deviation value based on the second average power consumption in the pure electric mode and the third average power consumption based on SOC calibration;
When the first deviation value is smaller than the second deviation value, determining that the first average power consumption of the full mileage is the estimated average power consumption;
and when the first deviation value is larger than or equal to the second deviation value, determining that the second average power consumption in the pure electric mode is the expected average power consumption.
Specifically, for the calculation modes of the two average power consumption, calculation of average power consumption deviation may be further implemented, for example, first determining third average power consumption E3 based on SOC calibration, where E3 is average power consumption based on SOC calibration, and the unit is kWh/100km, where e3= [ (k3×Δsoc)/cumulative mileage ] ×100; Δsoc=soc1-SOC 2.
Where K3 is a calibrated value, which is related to the degree of the power battery 30 on the hybrid vehicle, for example, the degree of the battery of the hybrid vehicle is 21kWh, k3=21 kWh; SOC1 is the starting power amount when calculating the average power, and SOC2 is the ending power amount.
Further, determining a corresponding deviation value, for example, a first deviation value q1= [ (E1-E3)/E3 ]. Times.100%, based on the third average power consumption based on SOC calibration; the second deviation value q2= [ (E2-E3)/E3 ]. Times.100%. A special calculation module can be arranged in the HCU to calculate the estimated average power consumption E4 in the full range, wherein when Q1< Q2, the actual average power consumption E4 = E1; when Q1 is equal to or greater than Q2, the actual average power consumption e4=e2.
Further, when the average power consumption is calculated, signal transmission is performed between the vehicle controller and other controllers, so as to implement the above calculation method of average power consumption, as shown in table 2 below, where the signals include four types of HCU input signals, HCU output signals, HCU internal variables, and HCU internal standard amounts.
The HCU input signal, namely the signal input to the HCU by other controllers, is used for supporting the HCU to calculate the electricity consumption; the HCU output signal, namely, after the HCU calculates the electricity consumption, is output to the instrument controller so as to display the average electricity consumption through the instrument; the HCU internal variable, namely the HCU receives input signals of other controllers, and the internal variable is set through the internal conversion or calculation of the HCU; the internal standard quantity of the HCU, namely, some preset standard quantity set by the HCU for calculating the electricity consumption, can be adaptively adjusted.
Table 2 average power consumption calculation signal table
When the estimated average electricity consumption E4 is obtained in the above manner, display of the actual average electricity consumption may also be achieved, which includes: obtaining default average power consumption; determining an actual average power consumption based on the default average power consumption and the corresponding first weight value and the predicted average power consumption and the corresponding second weight value;
Specifically, the display rules here include, for example:
(1) Updated every 1s or 30 meters (in order of first arrival);
(2) Resetting the accumulated electric quantity and accumulated mileage after Reset;
(3) The "-" is displayed within, for example, 300 meters (calibratable) after each Reset, the default average electricity consumption E5 (which may also be the average electricity consumption of the vehicle bulletin) is displayed after 300 meters, and gradually changes from the default value to the actual value within, for example, 7 minutes (calibratable), as follows:
Determining an actual average power consumption E6, wherein E6, e6=e5×f1+e4×f2 is determined by the following formula, wherein f1 is a weight of a default average power consumption, which varies linearly from 100% to 0; f2 is the weight of the expected average power consumption, which varies linearly from 0 to 100%, where f1+f2=1. Finally, the actual average electricity consumption value E6 is displayed through the vehicle instrument, and can be rounded to 1 bit after the decimal point.
Further, a filtering algorithm may be employed in performing the instantaneous power consumption and average power consumption calculations. Specifically, in the above calculation process, in order to prevent abrupt change of the discharge power and the vehicle speed of the battery, filtering processing is required to remove burrs, so that the numerical values are continuous and smooth, and a first-order filtering is added to the algorithm to perform filtering processing on the parameters, wherein the first-order filtering algorithm is as follows:
Filter result value = a this sample value + (1-a) last filter result value, where a is a number between 0-1; thus, the filter result value of the battery discharge power through the filter algorithm is as follows:
P_result=a*new_value1+（1-a）*old_value1；
It can be understood that discharge power= BattVol × BattCrt =p_result;
The result value of the vehicle speed through the filtering algorithm is as follows:
V_result= a*new_value2+（1-a）*old_value2；
it is understood that vehicle speed=vspd=v_result.
In a specific embodiment, as shown in fig. 3, when the instantaneous electricity consumption is calculated, two calculation modules, namely a first calculation module and a second calculation module, are arranged in the whole vehicle controller, wherein the first calculation module is used for calculating hundred kilometers of electricity consumption, and the second calculation module is used for calculating the hour of electricity consumption.
The method comprises the following specific steps:

(4) Calling a second calculation module to calculate the power consumption of the hour;
(5) In the second calculation module, a sub-module C is entered, and the calculation of the second instantaneous power consumption P2 is entered.
In another specific embodiment, as shown in fig. 4, when the average power consumption is calculated, three calculation modules, namely a calculation module three, a calculation module four and a calculation module five, are arranged in the whole vehicle controller, wherein the calculation module three is used for calculating the average power consumption in the whole range, the calculation module four is used for calculating the average power consumption in the pure electric mode, and the calculation module five is used for calculating the average power consumption based on the SOC calibration.

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