Referring to fig. 2, an embodiment of a vehicle information determination method of the present application is presented. In this embodiment, the vehicle information determination method includes:
step S10, acquiring the driving mileage of a vehicle in a target time period, the residual electric quantity change value of a power battery system of the vehicle in the target time period and the hydrogen consumption of a hydrogen fuel battery system of the vehicle in the target time period;
in this embodiment, the target time period is a time period in which the running state parameter satisfies the preset condition in the running process of the vehicle, and is a time period in which the duration is not fixed. In other embodiments, the target time period may also be a preset time period having a fixed duration.
In the present embodiment, the end time of the target period is the current time. In other embodiments, the target time period may also be a time period prior to the current time.
The starting time of the target time period may be the power-on time of the vehicle, or may be the time when the vehicle runs to reach a preset condition after power-on, or may be the time when a preset instruction input by a user is received.
The driving range is the total driving range of the vehicle in the target time period. The mileage detected by the odometer at the starting moment of the target time period is defined as a first mileage, the mileage detected by the odometer at the ending moment of the target time period is defined as a second mileage, and the driving mileage can be determined according to the difference value between the second mileage and the first mileage.
The hydrogen consumption is the total amount of hydrogen consumed by the vehicle during the target period. Specifically, in this embodiment, the period from the start of the continuous running of the vehicle to the start of the power-on time to the power-off time is defined as a power-on period, and the target time period belongs to the same power-on period, and may be determined according to the deviation amount between the remaining hydrogen amount in the hydrogen fuel cell system detected at the start time of the target time period and the remaining hydrogen amount in the hydrogen fuel cell system detected at the end time of the target time period; the intermediate time before the start time and the end time in the target time period can also be determined, and the hydrogen consumption can be determined according to the residual hydrogen amount of the hydrogen fuel cell system respectively corresponding to the start time, the intermediate time and the end time.
The residual electric quantity change value is a change characteristic value of the residual electric quantity of the power battery system in a target time period. Defining the residual electric quantity of the power battery system at the starting moment of the target time period as a first electric quantity, defining the residual electric quantity of the power battery system at the ending moment of the target time period as a second electric quantity, and determining the residual electric quantity change value according to the difference value between the second electric quantity and the first electric quantity. The positive value of the change in the remaining power indicates that the remaining power becomes large in the target period, and the negative value of the change in the remaining power indicates that the remaining power becomes small in the target period.
And step S20, determining the target unit mileage hydrogen consumption of the vehicle according to the residual electric quantity change value, the driving mileage and the hydrogen consumption.
The target unit mileage hydrogen consumption is the average hydrogen amount consumed by the hydrogen fuel cell system when the vehicle travels in unit mileage. In the present embodiment, the unit mileage is 100 km, and the target unit mileage hydrogen consumption is the average hydrogen amount consumed by the hydrogen fuel cell system every 100 km the vehicle travels. In other embodiments, the unit mileage may be other values of unit mileage, such as 1000 km, 10 km, 1 km, etc.
The corresponding relation between the residual electric quantity change value, the driving mileage and the hydrogen consumption and the target unit mileage hydrogen consumption is established in advance, the corresponding relation can comprise a calculation formula, a mapping relation and the like, and the target unit mileage hydrogen consumption corresponding to the residual electric quantity change value, the driving mileage and the hydrogen consumption can be determined based on the corresponding relation.
In one implementation of the embodiment, the driving mileage is corrected according to the remaining power change value, the corrected mileage is obtained, and the hydrogen consumption of the target unit mileage is determined according to the corrected mileage and the hydrogen consumption.
In another implementation manner of the embodiment, the hydrogen consumption is corrected according to the residual electric quantity change value, the corrected hydrogen consumption is obtained, and the target unit mileage hydrogen consumption is determined according to the corrected hydrogen consumption and the driving mileage.
In still another implementation manner of the present embodiment, the driving mileage is corrected according to the remaining power variation value to obtain a corrected mileage, the hydrogen consumption is corrected according to the remaining power variation value to obtain a corrected hydrogen consumption, and the target unit mileage hydrogen consumption is determined according to the corrected hydrogen consumption and the corrected mileage.
According to the vehicle information determining method provided by the embodiment of the invention, the target unit mileage hydrogen consumption of the vehicle is determined by combining the driving mileage of the vehicle in the target time period, the residual electric quantity change value of the power battery system and the hydrogen consumption, instead of independently determining the target unit mileage hydrogen consumption of the vehicle according to the detected driving mileage and the hydrogen consumption, the obtained target unit mileage hydrogen consumption can accurately reflect the influence of the operation of the power battery system on the hydrogen consumption of the hydrogen fuel battery system under different working conditions, and the actual unit mileage hydrogen consumption of the vehicle is more attached, so that the accuracy of the obtained vehicle unit mileage hydrogen consumption is effectively improved, and the accuracy of vehicle performance evaluation is improved.
Further, based on the above embodiment, another embodiment of the vehicle information determining method of the present application is proposed.
In this embodiment, referring to fig. 3, the step S20 includes:
s21, correcting the driving mileage according to the residual electric quantity change value to obtain a corrected mileage;
and determining a mileage correction value according to the residual electric quantity change value, and increasing or decreasing the driving mileage according to the mileage correction value to obtain a corrected mileage.
Different residual electric quantity change values correspond to different mileage correction values. Specifically, a correspondence between the remaining capacity change value and the mileage correction value may be established in advance, the correspondence may include a form of calculation, a mapping, etc., and the mileage correction value corresponding to the remaining capacity change value may be determined based on the correspondence. For example, the mileage correction value can be calculated by substituting the residual electric quantity change value into a preset formula; for another example, the mileage correction value may be obtained by looking up a table of the remaining power change value, and so on.
In this embodiment, the power consumption per unit mileage of the power battery system is obtained, and the ratio of the remaining power variation value to the power consumption per unit mileage is used as the mileage correction value. The power consumption per unit mileage may be WLTC power consumption notice value, or the power consumption per unit mileage may be a power consumption value obtained according to a certain experimental cyclic test, or the power consumption per unit mileage may be an average power consumption value within a unit mileage calculated by accumulating parameters collected according to a vehicle driving process, and so on.
For example, mileage correction value Deltad SOC ＝(SOC 2 -SOC 1 )/PC，SOC 2 The remaining power of the power battery system at the end of the target period, SOC 1 Residual capacity of the power battery system at the start time of the target period, (SOC) 2 -SOC 1 ) And the PC is the power consumption of the unit mileage as the residual power change value. Correction mileage d=d 1 +Δd SOC ，d 1 Is the driving range within the target time period.
And S22, determining the hydrogen consumption of the target unit mileage according to the hydrogen consumption and the corrected mileage.
And determining the ratio of the hydrogen consumption to the corrected mileage as the first unit mileage hydrogen consumption of the vehicle in the target time period, and determining the target unit mileage hydrogen consumption according to the first unit mileage hydrogen consumption.
In this embodiment, determining a target unit mileage hydrogen consumption of the vehicle according to the first unit mileage hydrogen consumption and the second unit mileage hydrogen consumption; the second unit mileage hydrogen consumption is determined according to preset unit mileage hydrogen consumption obtained through pre-testing under preset working conditions.
In other embodiments, the first unit mileage hydrogen consumption may also be directly taken as the target unit mileage hydrogen consumption.
In other embodiments, the target unit mileage hydrogen consumption may also be determined according to a preset number of first unit mileage hydrogen consumption corresponding to a preset number of target time periods before the current time.
In the embodiment, the driving mileage is corrected through the residual electric quantity change value to obtain the corrected mileage, the obtained corrected mileage can exclude the influence of the operation of the power battery system, the driving mileage contributed by the hydrogen fuel battery system in the target time period is accurately reflected, and based on the driving mileage, the target unit mileage hydrogen consumption is determined by combining the corrected mileage and the hydrogen consumption, so that the accuracy of the obtained vehicle unit mileage hydrogen consumption is improved, and the accuracy of the vehicle performance evaluation is improved.
Further, in this embodiment, when the remaining power change value increases corresponding to the remaining power, the correction mileage is greater than the driving mileage; and when the residual electric quantity corresponding to the residual electric quantity change value is reduced, the correction mileage is smaller than the driving mileage.
When SOC2 is larger than SOC1, the hydrogen fuel cell system charges the power cell system, and the mileage correction value delta d is shown SOC The value of the correction mileage is positive, the correction mileage is larger than the driving mileage, the electric quantity generated by the hydrogen fuel cell system in the charging process is converted into a corresponding mileage correction value, and the corresponding mileage correction value is added into the driving mileage, so that the unit mileage hydrogen consumption calculated based on the correction mileage can accurately reflect the actual hydrogen consumption condition of the hydrogen fuel cell system, and the accuracy of the determined unit mileage hydrogen consumption of the vehicle is further improved.
When SOC2 is smaller than SOC1, the power battery system is powered in the running process of the vehicle, and the mileage correction value delta d is indicated SOC The value of the mileage is negative, the correction mileage is smaller than the driving mileage, the electric quantity consumed by the power battery system in the driving process is converted into a corresponding mileage correction value, and the corresponding mileage correction value is deducted from the driving mileage, so that the unit mileage hydrogen consumption calculated based on the correction mileage can accurately reflect the actual hydrogen consumption condition of the hydrogen fuel battery system, and the accuracy of the determined unit mileage hydrogen consumption of the vehicle is further improved.
Further, based on any one of the above embodiments, a further embodiment of the vehicle information determining method of the present application is provided. In this embodiment, referring to fig. 4, the step S10 includes:
step S11, acquiring a running state parameter of the vehicle between a current first moment and a second moment before the first moment;
the running state parameter here is specifically a state parameter related to the operation of the vehicle battery system during running of the vehicle.
The driving state parameter may include a state of charge parameter of the power battery system and/or a mileage of the vehicle, etc. The driving state parameter may be a preset fixed parameter or a parameter selected according to the actual running condition of the vehicle.
The second time here may be the power-on time of the vehicle, the time when the vehicle last traveled reaches the preset condition (the same concept as the preset condition in step S12), or the time when the preset instruction input by the user is received.
Specifically, the state parameter in the running process of the vehicle can be detected at the second moment to serve as the first parameter, the state parameter in the running process of the vehicle can be detected at intervals, the state parameter in the running process of the vehicle detected at the current moment is taken as the second parameter, and whether the first parameter and the second parameter meet the preset condition is determined.
And step S12, when the running state parameter meets a preset condition, determining a time period between the first moment and the second moment as the target time period, and acquiring the running mileage, the residual electric quantity change value and the hydrogen consumption corresponding to the target time period.
The preset condition can be a preset fixed condition or a condition selected according to the actual running condition of the vehicle. The preset conditions are different if the running state parameters are different. The preset conditions may include a target value interval to be reached by the running state parameter or a target relationship with a preset parameter threshold, etc.
The running state parameters meet preset conditions, and indicate that the detected running mileage, the residual electric quantity change value and the hydrogen consumption between the first moment and the second moment are accurate, and the corresponding running mileage, residual electric quantity change value and hydrogen consumption are further determined by taking the first moment and the second moment as target time periods for the target unit mileage hydrogen consumption of the vehicle, so that the accuracy of determining the unit mileage hydrogen consumption is further improved.
Further, in the present embodiment, step S11 includes: acquiring an operating state of an energy recovery operation of the vehicle; when the running state is an opening state, acquiring mileage of the vehicle running between the first moment and the second moment; when the running state is a closed state, acquiring a change value of the residual electric quantity of the power battery system between the first moment and the second moment; wherein the running state parameter includes the mileage or the change value.
The mileage detected by the odometer of the vehicle at the first moment is a third mileage, the mileage detected by the odometer of the vehicle at the second moment is a fourth mileage, and the difference between the third mileage and the fourth mileage is used as the mileage.
The residual electric quantity of the power battery system at the first moment is the third electric quantity, the residual electric quantity of the power battery system at the second moment is the fourth electric quantity, and the difference value between the third electric quantity and the fourth electric quantity is used as the change value.
When the vehicle is in a first mode (such as an passion mode, etc.), the energy recovery operation is started when the vehicle is in a sliding state or a braking state, and the source of the recovered energy may be a hydrogen fuel cell system and/or a power cell system, and the acquisition of relevant parameters is carried out in a target time period based on the mileage of the vehicle between the first moment and the second moment, so that calculation errors caused by energy recovery are avoided, and the accuracy of calculating the hydrogen consumption of the unit mileage of the vehicle is further improved.
When the vehicle is in the second mode (such as comfort mode, etc.), the energy recovery operation is closed when the vehicle is in the sliding state or braking state, the power battery system is charged without recovered energy, and the acquisition of relevant parameters is carried out in the target time period based on the change of the residual electric quantity of the power battery system between the first moment and the second moment, so that the accuracy of the hydrogen consumption amount of the unit mileage of the vehicle is further improved.
Further, in this embodiment, the preset condition includes that the mileage is greater than or equal to a preset mileage or that the change value is greater than or equal to a preset electric quantity change value. Based on this, step S12 includes:
when the driving state parameter comprises the mileage and the mileage is greater than or equal to a preset mileage, determining a time period between the first moment and the second moment as the target time period, determining the mileage as the driving mileage, and acquiring the residual electric quantity change value and the hydrogen consumption corresponding to the target time period;
when the running state parameter includes the change value and the change value is greater than or equal to a preset electric quantity change value, determining a time period between the first time and the second time as the target time period, determining the change value as the residual electric quantity change value, and obtaining the running mileage and the hydrogen consumption corresponding to the target time period.
In the embodiment, when the energy recovery operation is started, the detection data in the corresponding time period is applied to unit mileage hydrogen consumption calculation when the running mileage is large enough, so that deviation of unit mileage hydrogen consumption calculation caused by vehicle idling and energy recovery is avoided, the accuracy of the obtained unit mileage hydrogen consumption of the vehicle is effectively improved, the accurate evaluation of the performance of the vehicle such as the cruising mileage based on the obtained target unit mileage hydrogen consumption is ensured, and the accuracy of the vehicle performance evaluation is improved. When the energy recovery operation is closed, the detection data in the corresponding time period are applied to the unit mileage hydrogen consumption amount calculation when the change of the residual electric quantity is large enough, so that the calculation of the unit mileage hydrogen consumption amount is facilitated in time when the electric quantity fluctuates, the timeliness of the obtained vehicle unit mileage hydrogen consumption amount is improved, and the timeliness of vehicle performance evaluation is improved.
In other embodiments, the preset conditions may also include that the difference between the mileage and the preset mileage is greater than a preset value or that the difference between the change value and the preset power change value is greater than a preset value, and so on.
Further, based on any one of the above embodiments, a further embodiment of the vehicle information determining method of the present application is provided. In this embodiment, referring to fig. 5, after step S20, the method further includes:
step S30, determining a first endurance mileage of the vehicle according to the target unit mileage hydrogen consumption and the available hydrogen amount of the hydrogen fuel cell system;
the available hydrogen amount can be determined by the residual hydrogen amount obtained by direct detection by the detection device, or can be obtained by correcting the residual hydrogen amount obtained by direct detection.
In this embodiment, the available hydrogen amount of the hydrogen fuel cell system is determined according to the deviation amount of the residual hydrogen amount of the hydrogen fuel cell system at the current time and the preset hydrogen amount; the preset hydrogen amount is the minimum value of the hydrogen amount required by the normal operation of the hydrogen fuel cell system.
