Detailed Description

Further advantages and effects of the present application will become readily apparent to those skilled in the art from the disclosure herein, by referring to the accompanying drawings and the preferred embodiments. The application may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present application. It should be understood that the preferred embodiments are presented by way of illustration only and not by way of limitation.

The first embodiment of the present application provides a method for displaying fuel range, which can be applied to a system architecture as shown in fig. 1, where the system architecture is a hybrid vehicle and at least includes an acquisition unit 101, a processing unit 102 and a display unit 103, and the acquisition unit 101 and the display unit 103 respectively establish communication connection with the processing unit 102. The collection unit 101 may collect a signal representing the remaining fuel value, the processing unit 102 may calculate a calculated value (may also be simply referred to as a calculated value) of the fuel range according to the remaining fuel value and the average fuel consumption, and the display unit 103 may display the calculated value of the fuel range. Of course, the specific composition of the system architecture is not limited, as long as the above-described functions can be achieved.

Next, based on the system architecture, the fuel range display method is described in detail, as shown in fig. 2, and the fuel range display method includes:

in step 201, when the vehicle is operating in the hybrid mode, a remaining fuel amount and an average fuel consumption are obtained.

The residual oil quantity value refers to the current oil quantity in the oil tank, a collection signal representing the residual oil quantity value can be collected through an oil pump sensor in the oil tank, the collection signal of the oil pump sensor is sent to an instrument controller, and the residual oil quantity value is obtained by the instrument controller according to the collection signal.

The average fuel consumption refers to the calibrated average fuel consumption AFC, and the average fuel consumption may be the average fuel consumption of a preset vehicle, or may be an input fuel consumption value calculated by a user according to the total fuel consumption and the total driving mileage under the mixed state according to a certain fixed period (such as several months) or in a maintenance period of the vehicle, and the input fuel consumption value is obtained by an input unit and is taken as the average fuel consumption, so that the actual average fuel consumption of the vehicle can be accurately reflected.

In one embodiment, before obtaining the remaining oil quantity value and the average oil consumption, the method further includes: and obtaining a fuel oil endurance mileage display value. The fuel range display value may be a display value (may also be simply referred to as a display value) displayed on a display interface such as an instrument panel or a central control screen, and the fuel range display value performs range initialization when a preset condition is satisfied, where the preset condition includes: the vehicle is refueled or the battery of the vehicle is powered up again.

In this embodiment, after the vehicle is refueled, since the remaining fuel value changes significantly, the fuel range display value needs to be initialized, and after the battery of the vehicle is powered down and powered up again, since the vehicle condition may change, the fuel range display value needs to be initialized, so as to ensure the accuracy of the display value.

The process of initializing the endurance mileage comprises the following steps: and acquiring a resistance signal of the oil pump sensor, if the resistance signal is invalid, displaying a fuel range display value in a first display mode, if the resistance signal is valid, determining the current oil quantity according to the resistance signal, obtaining a range calculation value according to the current oil quantity and the average oil consumption, and taking the range calculation value as the fuel range display value, wherein if the fuel range display value is smaller than a preset range threshold, displaying the fuel range display value in a second display mode.

In this embodiment, when the range is initialized, it is first determined whether the resistance signal of the oil pump sensor is valid, for example, whether the resistance signal is within a preset valid value interval. If the current display value represents that the acquired resistance signal is invalid, the vehicle needs to be checked and then the specific fuel mileage display value is checked.

If the resistance signal is effective, the residual oil quantity value (namely the current oil quantity) in the current oil tank can be determined, further, a cruising calculation value is obtained according to the residual oil quantity value and the average oil consumption, and the cruising calculation value is updated to an interface for displaying the fuel cruising mileage display value to serve as the initialized fuel cruising mileage display value.

Of course, if the remaining fuel quantity value is small, for example, the obtained fuel range display value is smaller than 50km, the fuel range value can be displayed in a second display mode different from the normal display mode, for example, specific mileage digits are not displayed, or the fuel range value is displayed in a unique color or style (for example, the normal display mode is a green font and often displayed, and at the moment, the fuel range value can be a red font and flashing display, etc.), so as to prompt the user that the fuel quantity is low, and the fuel needs to be timely replenished. Specifically, in both the first display mode and the second display mode, text prompt information corresponding to the cause of the abnormality can be added, and voice prompt information corresponding to the cause of the abnormality can also be added to remind the user of timely and correctly processing.

Specifically, some users may not be familiar with more display modes, and the first display mode and the second display mode may be set to be the same, without limitation.

And 202, obtaining a calculated fuel oil continuous voyage mileage value according to the residual fuel oil value and the average fuel oil consumption.

The average fuel consumption cannot change along with the running of the whole vehicle (only can change when the user adjusts), and the residual fuel quantity value changes in real time according to the signals acquired by the fuel pump sensor, so that the obtained fuel range calculation value also changes in real time. It should be appreciated that the period of change may be equal to the period of the oil pump sensor acquisition signal.

And 203, determining a compensation coefficient according to the calculated fuel range value and the current fuel range display value.

In one embodiment, determining the compensation coefficient according to the calculated fuel range value and the current fuel range display value includes: determining a first difference value of a current fuel range display value and a fuel range calculation value, determining a target coefficient matched with the first difference value from a preset coefficient strategy, and taking the target coefficient as a compensation coefficient.

In this embodiment, the compensation coefficient may be determined according to the magnitude relation between the calculated fuel mileage (hereinafter also referred to as a calculated value or DTE 1) and the displayed fuel mileage (hereinafter also referred to as a displayed value or DTE 2), for example, when the calculated value is equal to the displayed value, the displayed value may decrease according to the normal driving distance, i.e. the whole vehicle travels 1km, the DTE2 decreases by 1km, when the calculated value is smaller than the displayed value, the displayed value may decrease according to a faster speed, i.e. the compensation coefficient is 0.8, the whole vehicle travels 0.8km, the DTE2 decreases by 1km, when the calculated value is greater than the displayed value, the displayed value may decrease according to a slower speed, i.e. the compensation coefficient is 1.2, the whole vehicle travels 1.2km, and the DTE2 decreases by 1.

In this embodiment, the difference degree of the display value and the calculated value may be determined according to the first difference between the display value and the calculated value, different target coefficients may be determined according to the different difference degrees, and the display value may calculate the speed of reduction according to the target coefficients and the driving range.

In this embodiment, the fuel range display value may add a compensation coefficient to the process that the display value decreases along with the driving range according to the current actual condition of the vehicle, so that the absolute driving 1km display value is not reduced by 1km, and the actual range according to the current actual condition is more truly reflected, so that the fuel range display value is matched with the actual range that the residual fuel can range under the current condition, the range display deviation is directly and effectively reduced, the accuracy of the fuel range display value of the hybrid vehicle is improved, and the user experience is improved.

In one embodiment, determining the target coefficient matched by the first difference value from a preset coefficient strategy includes:

if the modulus of the first difference is smaller than the first threshold, the target coefficient is determined to be one. Since the calculated value is a value which changes more frequently, the difference between the display value and the calculated value is smaller, and the difference is zero, it can be considered that the modulus of the first difference is smaller than the first threshold, that is, the modulus is equal to the first threshold, for example, -10 < DTE2-DTE1 < 10, the display value is considered to be equal to the calculated value, and the target coefficient, that is, the supplementary coefficient is one, that is, the whole vehicle travels 1km, and DTE2 is reduced by 1km.

If the first difference is in the first interval, determining the target coefficient as the first coefficient, wherein the minimum value in the first interval is larger than or equal to the first threshold value, and the first coefficient is smaller than one. For example, when 10 < DTE2-DTE1 < 20, the first coefficient may be 0.7, when 20 < DTE2-DTE1 < 30, the first coefficient may be 0.6, and when 30 < DTE2-DTE1 < 40, the first coefficient may be 0.5, i.e. the smaller the first interval characterization calculation value is than the display value and the larger the difference is, the smaller the first coefficient is, so as to adapt to the current actual working condition, and improve the accuracy of the display value.

If the first difference is in the second interval, determining the target coefficient as a second coefficient, wherein the maximum value in the second interval is smaller than or equal to a negative first threshold value, and the second coefficient is larger than one. For example, when-20 < DTE2-DTE1 < -10, the second coefficient may be 1.2, when-30 < DTE2-DTE1 < -20, the second coefficient may be 1.5, i.e. the second interval characterization calculation value is larger than the display value and the difference is larger, the second coefficient is larger, so as to adapt to the current actual working condition, and improve the accuracy of the display value.

It should be noted that, the first interval, the second interval, and the specific values of the first coefficient and the second coefficient of the first difference in this embodiment are all illustrated and do not represent specific limitations.

And 204, updating and displaying the fuel oil continuous voyage display value according to the compensation coefficient and the driving distance of the vehicle.

According to the method, the compensation coefficient can be determined according to the calculated fuel range value and the display value of the fuel range, and the display value of the fuel range is updated through the compensation coefficient and the driving range, so that the display value of the fuel range is matched with the actual range of the residual fuel range under the current working condition, the display deviation of the range is directly and effectively reduced, the accuracy of the display value of the fuel range of the hybrid vehicle is improved, and the user experience is improved.

In one embodiment, updating and displaying the fuel range display value according to the compensation coefficient and the driving range of the vehicle includes:

if the compensation coefficient is equal to one, determining a second difference value between the fuel range display value and the driving range, and displaying the second difference value as an updated fuel range display value;

In this embodiment, during the running process of the vehicle, for example, the fuel mileage display value at the first time is 200km, the running mileage is 1km from the first time to the second time, the display value at the second time is determined according to the compensation coefficient, if the compensation coefficient is one, the second difference value is 200km-1 km=199 km, that is, the display value at the second time is 199km, if the compensation coefficient is 0.5, the first target mileage is 1 km/0.5=2 km, the display value at the second time is 200km-2 km=198 km, if the compensation coefficient is 1.2, the second target mileage is 1 km/1.2=0.83 km, and the display value at the second time is 200km-0.83 km= 199.17km (a decimal may be actually displayed).

In a specific embodiment, a fuel range display method may be applied to the system architecture as shown in fig. 3.

The system architecture at least comprises an oil pump sensor, an instrument controller, a vehicle-mounted infotainment system, an engine management system (Engine Management System, abbreviated as EMS) controller and a brake controller.

The oil pump sensor mainly sends the residual oil quantity in the oil tank to the instrument controller in real time for collection, calculates the residual oil quantity of the current whole vehicle, and achieves the function of the collection unit 101.

The instrument controller mainly receives signals of all components to process, calculates corresponding endurance mileage values according to collected residual oil quantity and driving mileage, and displays the endurance mileage values according to corresponding compensation coefficient logic, so that the functions of the processing unit 102 and the display unit 103 are realized.

The vehicle-mounted information entertainment system mainly transmits a driving mode (including an EV mode and an HEV mode) corresponding to the whole vehicle to a meter, and a meter controller judges whether to process calculation and display of a cruising value according to the driving mode.

And the EMS controller is used for mainly controlling the working state of the engine, sending a signal about whether the engine is started to the instrument controller for judgment and processing, and sending oil injection information in an idle state to the instrument controller for calculation and processing.

The brake controller is mainly used for processing and calculating the running speed of the whole vehicle, sending a vehicle speed signal value to the instrument controller and calculating mileage information.

After the whole vehicle is refueled or the storage battery is charged again, the logic of the fuel range display method is shown in fig. 4, wherein the logic related to range initialization and driving display is specifically as follows:

initializing the endurance mileage:

when the instrument controller samples the resistance value signal of the oil pump sensor, and when the acquired signal is invalid (open circuit or short circuit), the cruising display is carried out.

If the detected resistance value signal is valid, and the fueling action is judged through the sampling of the resistance value, namely, the currently collected oil mass resistance value signal judges the residual oil mass value L and the calibrated oil consumption value are subjected to calculation AFC to obtain a cruising mileage calculation value, and the currently calculated value (the calculation value is set as DTE 1) is used as a display value to be displayed (the display value is set as DTE 2), and at the moment, DTE2=DTE1.

If the instrument controller detects the reset action of the whole vehicle storage battery, the resistance signal is collected again to judge the residual oil value L, the DTE1 is calculated, and the DTE2 is displayed according to the DTE1.

When the duration DTE2 indicates less than 50km, indicating that the current fuel level is low, the user needs to replenish fuel as soon as possible, and DTE2 indicates "- - - - - - -, as shown.

Travel display logic:

when the whole vehicle is in running (the vehicle speed is greater than a set threshold value), if the driving mode is EV mode, the pure electric driving is performed at the moment, the residual oil quantity display is not corrected, meanwhile, the calculated value DTE1 of the continuous mileage is kept unchanged, and the display value DTE2 is kept unchanged.

And when the driving mode is switched to the HEV mode in the running process, the hybrid running is indicated at the moment, and when the engine is started to participate in the whole vehicle driving or charge a battery in the hybrid running, the consumption of the oil quantity of the whole vehicle is indicated. The oil consumption is not calculated according to the accumulation of signals sent by the electronic injection EMS, but judged according to the real-time acquisition signals of the sampling oil pump sensor. At this time, the range dte1=the remaining oil quantity value L/the calibrated average fuel consumption AFC is calculated. The display value DTE2 of the continuous voyage is gradually reduced according to the driving mileage, and meanwhile, the display value DTE2 is compared with DTE1 in real time, and the logic is as follows:

when-10 is less than DTE2-DTE1 is less than 10, the calculated value is equivalent to the display value, and DTE2 is decreased according to the compensation coefficient 1, namely, the DTE2 is decreased by 1km every time the whole vehicle runs for 1km.

When the DTE2 is more than 10 and less than 20, the calculated value is less than the display value, the current oil consumption is high, the rapid approximation is required, the DTE2 is decreased according to the compensation coefficient of 0.7, namely, the DTE2 is decreased by 1km when the whole vehicle runs for 0.7 km.

When DTE2-DTE1 is less than-10, the calculated value is larger than the display value, the current oil consumption is lower, slow approximation is needed, DTE2 is decreased according to the compensation coefficient 1.2, namely, the DTE2 is decreased by 1km every time the whole vehicle runs for 1.2 km.

It should be understood that when DTE2-DTE1 > 20, the compensation coefficient should be smaller than 0.7, and of course, the cases of DTE2-DTE1 < -10 may be subdivided, and it is not repeated here, and it should be noted that the above compensation coefficients are only illustrative, and specific parameters are set according to actual needs and are not limited.

During HEV mode driving, if the engine stops working due to the whole vehicle working condition requirement, the fuel consumption is not carried out at this time. However, in the actual working condition, the starting intervention of the engine is irregular, and in order to achieve a more accurate display effect, DTE2 is also required to be compared with DTE1, if DTE2-DTE1 is greater than 0, DTE2 is continuously corrected and displayed according to the corresponding relation of the driving distance compensation coefficient until dte2=dte1. If DTE2-DTE1 is less than or equal to 0, the DTE2 value is kept unchanged temporarily.

Idle speed display logic:

after the whole vehicle runs for a certain distance, entering an idle state, if the vehicle is in an EV mode, enabling an engine not to be started, enabling DTE1 not to perform calculation processing, enabling DTE1 to be kept all the time, and not performing display correction processing; if the HEV mode is switched at this time, after the engine is started, calculating the fuel consumption L1 in a period of time according to the fuel consumption information sent by the EMS controller 4, and simultaneously calculating a new DTE1 value according to the calibrated fuel consumption value AFC, and updating and displaying the DTE2 according to the difference between the DTE1 value and the DTE 1; in the HEV mode, if the engine is not started, the range is not calculated and displayed at this time.

The logic further optimizes the problem of inaccurate calculation and display under some special complex working conditions, mainly fixes the average fuel consumption with complex functional logic, reduces the deviation calculation of intermediate variable values, and improves the accuracy of the continuous voyage mileage display. The objective and accurate information is used for reasonably planning the journey and charging or oiling in time by referring to the vehicle running information for the user.

In this embodiment, in the display of the fuel range, the remaining fuel amount, the calibrated average fuel consumption AFC, the driving mode, the range calculation value, the compensation coefficient between calculation and display, and the like are involved. The value of the AFC is solidified according to the comprehensive oil consumption of the whole vehicle, does not change along with the running of the whole vehicle, and can be configured online for changing.

When the whole vehicle runs in EV mode, the engine of the whole vehicle does not participate in driving, fuel consumption is not carried out, at the moment, various variable parameter values for calculating the endurance mileage are kept unchanged, and the endurance display value is kept unchanged.

When the whole vehicle runs in the HEV mode, the whole vehicle is driven according to the hybrid mode, and at the moment, if the engine is involved, the calculation and display of the cruising value are normally carried out. If the engine is not involved, the calculated value of the cruising mileage is required to be compared with the display value, and if the cruising display value is larger than the calculated value, the cruising display value is refreshed and changed according to the compensation coefficient corresponding table until the cruising display value is consistent with the cruising calculated value.

In the running process, the descending speed of the continuous voyage mainly depends on the change of the oil quantity, and if the descending speed is fast, the fuel consumption of a user is high at the moment, and the user needs to pay attention to and improve the driving habit.

The application mainly aims to correspond the fuel oil duration display with the residual oil quantity information display on the fuel oil meter, improve the accuracy of the fuel oil duration display, avoid the running risk caused by misjudgment of a user due to display deviation, guide the user to run in a fuel-saving mode, improve the driving pleasure and the like.
