[0002] Fuel level display is an important information for human-vehicle interaction. The fuel tank sensor (or fuel level sensor) consists of an oil float and a resistance sensor. When the oil in the tank rises or falls, the oil float will rise or fall accordingly, thereby driving the resistance of the sliding rheostat of the resistance sensor to increase or decrease. The controller collects the resistance of the fuel tank sensor, and then determines the amount of oil in the tank (percentage) based on the corresponding relationship between resistance and oil level, and then displays the specific amount of oil (percentage) through the instrument.

[0003] The sliding part of the sliding rheostat is composed of an alloy of oil silver and palladium. Oil contains sulfur, and the oil tank sensor is easily immersed in oil for a long time to produce silver sulfide, which causes the resistance of the sliding rheostat to increase at the same liquid level, resulting in a smaller amount of oil collected by the controller (conversely, the smaller the resistance, the higher the oil level), and even the situation where the oil is full but the instrument shows that it is not full, resulting in inaccurate oil display.

[0033] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0034] A method and device for displaying the amount of oil according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0035] Figure 1 is a schematic diagram of an application scenario of an embodiment of the present application. The application scenario may include a vehicle controller 101 (referred to as "VCU"), a fuel level sensor (or fuel tank sensor) 102, and an in-vehicle infotainment system 103 (referred to as "IVI") deployed on a new energy vehicle. The vehicle controller 101 can be connected to a network through Ethernet or CAN The bus establishes communication connection with the oil level sensor 102 and the vehicle infotainment system 103. The oil level sensor 102 includes an oil float and a resistance sensor. When the oil in the oil tank rises or falls, the oil float will rise or fall accordingly, thereby driving the resistance of the sliding rheostat of the resistance sensor to increase or decrease.

[0036] The new energy vehicles in the embodiments of this application refer to vehicles that use new energy (non-traditional petroleum and diesel energy) and have advanced technology. These vehicles use new power systems that can effectively reduce vehicle emissions, reduce environmental impact, and improve energy efficiency. The new energy vehicles in the embodiments of this application include but are not limited to the following types of vehicles: electric vehicles (EV), battery electric vehicles (BEV), fuel cell electric vehicles (FCEV), plug-in hybrid electric vehicles (PHEV), and hybrid electric vehicles (HEV), etc.

[0037] During the use of the vehicle, first, the vehicle controller 101 collects the current resistance value of the sliding rheostat of the oil level sensor 102; if the sliding rheostat is in a normal state (i.e., the sliding rheostat has not reacted with the sulfur in the oil to generate silver sulfide), then the current oil level corresponding to the current resistance value is determined according to a preset first mapping relationship between the oil level and the resistance, and the current oil level is displayed on a vehicle instrument (such as an in-vehicle infotainment system 103); if the sliding rheostat is in an abnormal state (i.e., the sliding rheostat has reacted with the sulfur in the oil to generate silver sulfide), then the current oil level corresponding to the current resistance value is determined according to a preset second mapping relationship between the oil level and the resistance, and the current oil level is displayed on a vehicle instrument; wherein the second mapping relationship is determined based on the first mapping relationship and a resistance correction coefficient.

[0038] The technical solution provided by the embodiment of the present application is that the vehicle controller collects the current resistance value of the sliding rheostat of the oil level sensor, and then selects to use the first mapping relationship or the second mapping relationship to determine the current oil level corresponding to the current resistance value according to the state of the sliding rheostat (whether silver sulfide is generated); wherein the second mapping relationship is determined according to the first mapping relationship and the resistance correction coefficient, and when the sliding rheostat is in an abnormal state, the current oil level corresponding to the current resistance value can be determined by the corrected second mapping relationship, thereby solving the problem in the prior art that the resistance of the sliding rheostat becomes larger at the same liquid level due to the generation of silver sulfide caused by the oil tank sensor being immersed in oil for a long time, thereby causing inaccurate oil level display.

[0039] Figure 2 It is a flow chart of a method for displaying oil quantity provided in an embodiment of the present application. Figure 2 The oil quantity display method can be Figure 1 The vehicle controller 101 is used to execute. Figure 2 As shown, the oil level display method may specifically include the following steps:

[0040] Step S201, collecting the current resistance value of the sliding rheostat of the oil level sensor.

[0041] During the driving process of the vehicle, as the fuel consumption gradually increases, the oil in the fuel tank will gradually decrease, and the resistance of the sliding rheostat of the fuel level sensor 102 will gradually increase. The vehicle controller 101 can collect the current resistance value of the sliding rheostat of the fuel level sensor 102 in real time or regularly, and record the current collection time.

[0042] The current collection time refers to the time point when the vehicle controller 101 collects the current resistance value of the sliding resistor of the oil level sensor.

[0043] Step S202, if the sliding rheostat is in a normal state, the current oil volume corresponding to the current resistance value is determined according to a preset first mapping relationship between the oil volume and the resistance, and the current oil volume is displayed on the vehicle instrument.

[0044] The normal state of the sliding rheostat means that the sliding rheostat has not reacted with the oil in the oil tank to generate silver sulfide. Chemical testing and other means can be used to detect whether the sliding rheostat has generated silver sulfide, thereby determining the state of the sliding rheostat.

[0045] During the fuel tank design phase, a series of resistance and fuel quantity test results can be obtained through a refueling test (testing the resistance value during the process of injecting fuel into the fuel tank), and then a first mapping relationship between the fuel quantity and the resistance can be established.

[0046] As an example, the first mapping relationship between the oil volume and the resistance can be recorded and managed in the form of a table, as shown in Table 1.

[0047] Table 1 The first mapping relationship between oil volume and resistance

[0048]

[0049] In Table 1, , , ..., , Gradually increase, that is < <...< < ; , , ..., , Gradually decreases, that is > >...> > .

[0050] As an example, assume that the current resistance value of the sliding rheostat of the vehicle's oil level sensor collected by the vehicle controller 101 is , the oil level sensor does not generate silver sulfide (i.e., it is in normal state), then by querying the above Table 1, it can be obtained that Corresponding to the resistance in Table 1 , and the resistor The corresponding oil volume is , from which the current oil volume can be determined to be .

[0051] Afterwards, the vehicle controller 101 can obtain the current fuel level by looking up the table. The information is sent to the vehicle instrument (such as the in-vehicle infotainment system 103) for display. The user (such as the driver) can view the current fuel level of the vehicle's fuel tank through the screen of the vehicle instrument.

[0052] Step S203, if the sliding rheostat is in an abnormal state, the current oil volume corresponding to the current resistance value is determined according to a preset second mapping relationship between the oil volume and the resistance, and the current oil volume is displayed on the vehicle instrument.

[0053] The second mapping relationship is determined by the following steps:

[0054] Determine the basic resistance value of the sliding rheostat of the fuel level sensor when it is in a normal state; wherein the basic resistance value is the data measured by the preset range extender fuel consumption test;

[0055] Record the first resistance value to the second resistance value each time the vehicle fails to start the range extender due to fuel exhaustion. i Resistance value; where, i is an integer ≥ 2;

[0056] Between each time the vehicle is refueled and the next time it is refueled, the fuel consumption of the first range extender is counted to the j Range extender fuel consumption and total fueling from the first to the j Total refueling amount; of which, j is an integer ≥ 2;

[0057] According to the basic resistance value, the first resistance value to the i Resistance value, fuel consumption of the first range extender to the j Range extender fuel consumption and total fueling from the first to the j Total amount of oil added, determine the resistance correction factor;

[0058] A second mapping relationship is determined according to the first mapping relationship and the resistance correction coefficient.

[0059] As an example, when performing a range extender fuel consumption test, the vehicle controller 101 may collect the fuel resistance value when the range extender of a vehicle cannot be started due to fuel exhaustion, which is the basic resistance value and can be recorded as .

[0060] As another example, the above-mentioned range extender fuel consumption test may be performed multiple times on multiple vehicles (of the same model) to obtain the fuel resistance values ​​when the range extenders of the multiple vehicles in each test cannot be started due to fuel exhaustion, and the average value of the fuel resistance values ​​of the multiple tests on the multiple vehicles is calculated, and the average value is determined as the basic resistance value when the sliding rheostat of the fuel level sensor is in a normal state.

[0061] The vehicle controller 101 can record the first resistance value to the second resistance value each time the range extender cannot be started due to fuel exhaustion during the use of the vehicle within a preset collection period (the preset collection period can be set according to actual conditions, for example, the preset collection period can be set to 1 year). i The resistance value can be expressed as (corresponding to the first resistance value), ..., (Corresponding to i resistance value).

[0062] The vehicle controller 101 can collect the fuel consumption of the first range extender from the time the vehicle is refueled to the time the vehicle is refueled again within a preset collection period (for example, the preset collection period is 1 year). j The fuel consumption of the range extender can be expressed as (corresponding to the fuel consumption of the first range extender),..., (Corresponding to j In the embodiment of the present application, the vehicle controller 101 can receive the fuel consumption rate sent by the EMS (range extender) between each time the vehicle is refueled and the next time it is refueled, and then integrate the fuel consumption rate to obtain the fuel consumption of the first range extender to the second range extender. j Range extender fuel consumption.

[0063] The vehicle controller 101 counts the total fueling amount from the first filling to the next filling. j The total amount of oil added (the oil amount display is inaccurate due to the abnormal state of the sliding rheostat, and there may be a situation where the oil is not fully filled between two fillings) can be recorded as (corresponding to the first total refueling amount),..., (Corresponding to j The first total refueling amount refers to the total refueling amount between the first refueling and the second refueling. j The total amount of fuel is the amount of fuel in the vehicle. j Fill up the fuel tank to j+1 Total fueling between refuelings.

[0064] The technical solution provided in the embodiment of the present application collects the current resistance value of the sliding rheostat of the oil level sensor, and then selects to use the first mapping relationship or the second mapping relationship to determine the current oil level corresponding to the current resistance value according to the state of the sliding rheostat (whether silver sulfide is generated); wherein the second mapping relationship is determined according to the first mapping relationship and the resistance correction coefficient, and when the sliding rheostat is in an abnormal state, the current oil level corresponding to the current resistance value can be determined by the corrected second mapping relationship, thereby solving the problem in the prior art that the resistance of the sliding rheostat becomes larger at the same liquid level due to the generation of silver sulfide when the oil tank sensor is immersed in oil for a long time, thereby causing inaccurate oil level display.

[0083] In some embodiments, based on the resistance change rate mean and the resistance change rate standard deviation, the resistance change rate from the first resistance change rate to the second resistance change rate is calculated. i At least one target resistance change rate is selected from the resistance change rate, including:

[0084] Determine the upper limit value of the resistance change rate and the lower limit value of the resistance change rate based on the mean value of the resistance change rate and the standard deviation of the resistance change rate;

[0085] If the first resistance change rate is greater than or equal to the resistance change rate upper limit value and less than or equal to the resistance change rate lower limit value, the first resistance change rate is determined as the target resistance change rate;

[0086] Jordii If the resistance change rate is greater than or equal to the upper limit of the resistance change rate and less than or equal to the lower limit of the resistance change rate, i The resistance change rate is determined as a target resistance change rate.

Among them, the upper limit value of the resistance change rate is The lower limit of resistance change rate is .

For example, if the time difference is 6 months, then the ratio of the time difference (6 months) to the preset collection period (12 months) is less than 1, and the current collection time is within the first collection period. If the ratio of the calculated time difference to the preset collection period is greater than 1 and less than 2, it can be determined that the current collection time is within the second collection period. Similarly, if the ratio of the calculated time difference to the preset collection period is greater than 3 and less than 4, it can be determined that the current collection time is within the fourth collection period.

[0149] As an example, assuming that the preset collection period is 1 year, if the time difference between the current collection time when the vehicle control 101 collects the current resistance value of the sliding rheostat of the oil level sensor and the initial use time when the vehicle is newly equipped with the oil level sensor is less than or equal to 1, then it is determined that the current collection time is within the first collection period (i.e., within the first year). The start time of the first collection period (marked as ) is the initial use time of the fuel level sensor when it is newly installed on the vehicle (marked as ), the final time is the time point one year after the start time (marked as ).

[0150] In the first case, if the current acquisition time (marked by ) In the first collection cycle, if the sliding resistor of the oil level sensor is in a normal state, the current oil level corresponding to the current resistance value collected at the current collection time point is determined according to the first mapping relationship in Table 1 above.

[0151] In the second case, if the current acquisition time (marked by ) In the first collection cycle, if the sliding resistor of the oil level sensor is in an abnormal state, the current collection time is intercepted. To the start time of the first collection cycle The first resistance value to the i-th resistance value, the first range extender fuel consumption to the j-th range extender fuel consumption, and the first total refueling amount to the j-th total refueling amount recorded in the time period between; then, according to the basic resistance value, the first resistance value to the i-th resistance value, the first range extender fuel consumption to the j-th range extender fuel consumption, and the first total refueling amount to the j-th total refueling amount, determine the resistance correction coefficient; then, according to the first mapping relationship and the resistance correction coefficient, determine the second mapping relationship (as shown in Table 2 above). Finally, determine the current collection time according to the second mapping relationship The current oil volume corresponding to the current resistance collected.

[0152] When the sliding rheostat remains in an abnormal state, the current acquisition time The following collection time points to the final time point of the first collection cycle The current resistance collected is determined by querying the second mapping relationship in Table 2 to determine the corresponding current oil volume.

[0153] When the preset collection period expires (e.g., one year), and the second collection period (i.e., within the second year) is entered, the first collection period (from the start time) is intercepted. To the final time This period of time) records the first resistance value to the i Resistance value, fuel consumption of the first range extender to the j Range extender fuel consumption and total fueling from the first to thej Total refueling amount; then, according to the basic resistance value, the first resistance value to the i Resistance value, fuel consumption of the first range extender to the j Range extender fuel consumption and total fueling from the first to the j The total refueling amount is used to determine a first updated resistance correction coefficient; and the second mapping relationship is corrected according to the first updated resistance correction coefficient to obtain a corrected second mapping relationship.

[0154] Next, when the second acquisition period expires (for example, one year), the first resistance value recorded in the second period (from the start time to the end time of the second period) is intercepted to the first resistance value recorded in the second period. i Resistance value, fuel consumption of the first range extender to the j Range extender fuel consumption and total fueling from the first to the j Total refueling amount; then, according to the basic resistance value, the first resistance value to the i Resistance value, fuel consumption of the first range extender to the j Range extender fuel consumption and total fueling from the first to the j The total refueling amount is used to determine the second updated resistance correction coefficient, and then the above-corrected second mapping relationship is corrected according to the first updated resistance correction coefficient to obtain the second corrected mapping relationship.

[0155] It can be understood that when the third collection cycle expires, the second mapping relationship corrected after the second collection cycle expires can be iteratively corrected in accordance with the above method, which will not be described in detail herein.

[0156] That is to say, every time a preset collection cycle expires (such as after 1 year), the mapping relationship between the oil volume and the resistance in the previous preset collection cycle can be corrected based on the previous preset collection cycle with reference to the above embodiment, so as to obtain the mapping relationship between the oil volume and the resistance in the next preset collection cycle.

[0157] In this way, it can be avoided that the oil level sensor generates silver sulfide due to long-term contact with oil, which causes the resistance of its sliding rheostat to increase, thereby causing inaccurate collection and display of the oil level.

[0158] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.
