Description

Technical Field

[0001] The present application relates to the technical field of cruising range, and in particular to a method, device, medium and electronic device for obtaining the cruising range of alcohol fuel. Background Art

[0002] As energy consumption and environmental pollution caused by traditional fuel vehicles become increasingly serious, the automotive industry has begun to actively explore new power solutions.

[0003] As a transitional technology solution, hybrid electric vehicles (HEV) have rapidly emerged from the late 20th century to the early 21st century, becoming a bridge between traditional fuel vehicles and pure electric vehicles (BEV). At the same time, finding clean and efficient alternative fuels has also continued to be the focus of research in various countries. As a realistic renewable clean fuel, ethanol has attracted much attention because its physical, chemical and thermal properties are similar to those of gasoline and it can be produced from a variety of renewable resources such as sugarcane, starch plants, and wild plants. The research and development and application of ethanol engines are based on this background.

[0004] Since the ethanol content in the added ethanol gasoline can vary between E0 and E100, different proportions of ethanol will directly affect the calorific value of gasoline, making the method of calculating the cruising range of petrochemical gasoline impossible to apply to ethanol gasoline.

[0066] It should be particularly noted that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0067] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0068] The embodiment provided in this application is an embodiment of a method for obtaining the cruising range of alcohol fuel.

[0069] Combine the following Figure 1 The embodiments of the present application are described in detail.

[0070] Step S101, in a starting cycle of an alcohol fuel vehicle, obtaining the operating status of the vehicle in a target detection period and the theoretical value and planned display value of the cruising range.

[0071] Alcohol fuel vehicles refer to vehicles that have alcohol fuel added to the fuel.

[0072] The starting cycle process refers to the process from starting the vehicle to shutting down the vehicle. During a starting cycle, periodically check whether the planned displayed value of the cruising range is correct.

[0073] Running status, including driving status and idling status. In the process of obtaining the range, a crucial prerequisite is to accurately judge the running status of the vehicle.

[0074] The theoretical value of the cruising range is the cruising range value calculated by the first mathematical model of the cruising range.

[0075] The planned display value of the cruising range refers to the cruising range value originally planned to be displayed in the vehicle instrument panel and has not yet been displayed. The planned display value is the cruising range value calculated by the second mathematical model of the cruising range.

[0076] That is, the theoretical value of the cruising range and the planned display value are two different ways to obtain the cruising range value.

[0077] Step S102, when the deviation between the planned display value of the target detection cycle and the theoretical value is greater than a preset deviation threshold, the previous target cruising range value of the previous detection cycle immediately preceding the target detection cycle and the key influencing parameter values ​​associated with the operating state are obtained.

[0078] If the deviation between the planned display value and the theoretical value of the target detection cycle is greater than the preset deviation threshold, it can be understood that the gap between the planned display value and the theoretical value of the target detection cycle is relatively large, and the two values ​​are inconsistent, and adjustment is required. When the deviation between the planned display value and the theoretical value of the target detection cycle is less than or equal to the preset deviation threshold, the two values ​​are consistent, and the theoretical value or the planned display value of the target detection cycle is determined to be the target cruising range value of the corresponding target detection cycle.

[0079] The previous target cruising range value is the target cruising range value obtained in the previous detection cycle immediately preceding the target detection cycle. For example, if the target detection cycle is T, the previous detection cycle immediately preceding the target detection cycle is T-1.

[0080] When the vehicle is in a driving state, its fuel consumption is mainly affected by multiple factors such as vehicle speed, acceleration, road conditions, driving habits, etc. When the vehicle is in an idling state, its fuel consumption is relatively stable and is mainly affected by a few factors such as engine speed and ambient temperature. Therefore, the embodiment of the present application obtains the key influencing parameter values ​​associated with the operating state.

[0081] Step S103: obtaining a preset adjustment parameter value associated with the operating state based on the deviation value and a key influencing parameter value associated with the operating state.

[0082] The embodiment of the present application obtains corresponding preset adjustment parameter values ​​according to different operating states so as to dynamically adjust the cruising range.

[0083] The preset adjustment parameter value is an empirical value obtained through experiments. The preset adjustment parameter value is a dynamically obtained value.

[0084] In some specific embodiments, the key influencing parameter value includes a remaining oil value.

[0085] Accordingly, obtaining a preset adjustment parameter value associated with the operating state based on the deviation value and a key influencing parameter value associated with the operating state includes:

[0086] Step S102a: when the operating state is characterized as a driving state, obtaining a preset first adjustment parameter value associated with the driving state based on the deviation value and the remaining fuel value.

[0087] The preset first adjustment parameter value is an empirical value obtained through experiments.

[0088] The combination of the deviation value and the remaining fuel value of the planned display value and the theoretical value is different, and the corresponding preset first adjustment parameter value is also different. The preset first adjustment parameter value has a corresponding relationship with the deviation value and the remaining fuel value. The adjustment of the preset first adjustment parameter value obtained dynamically can make the target cruising range value finally obtained closer to the actual value.

[0089] Optionally, when the operating state is characterized as a driving state, a preset first adjustment parameter value associated with the driving state is obtained based on the deviation value and the remaining fuel value, including: when the operating state is characterized as a driving state, a preset first adjustment parameter value associated with the driving state is obtained by looking up a table based on the deviation value and the remaining fuel value.

[0090] In this specific embodiment, a first data set is established, and the first data set includes a preset first adjustment parameter value and a one-to-one correspondence with the deviation value and the remaining oil value. Applying the deviation value and the remaining oil value to the first data set can quickly obtain the corresponding preset first adjustment parameter. Not only does it save data space, but it also reduces the amount of data calculation and improves the response speed.

[0091] In some specific embodiments, the key influencing parameter values ​​include a remaining fuel value and an idle average fuel consumption value.

[0092] Accordingly, obtaining a preset adjustment parameter value associated with the operating state based on the deviation value and a key influencing parameter value associated with the operating state includes:

[0093] Step S102b: when the operating state is characterized as an idle state, a preset second adjustment parameter value associated with the idle state is obtained based on the deviation value, the remaining fuel value and the idle average fuel consumption value.

[0094] The preset second adjustment parameter value is an empirical value obtained through experiments.

[0095] Different combinations of the deviation value between the planned display value and the theoretical value, the remaining fuel value, and the idle average fuel consumption value have different corresponding preset second adjustment parameter values. The preset second adjustment parameter value has a corresponding relationship with the deviation value, the remaining fuel value, and the idle average fuel consumption value. The adjustment of the dynamically obtained preset second adjustment parameter value can make the target cruising range value finally obtained closer to the actual value.

[0096] Optionally, when the operating state is characterized as an idle state, a preset second adjustment parameter value associated with the idle state is obtained based on the deviation value, the remaining fuel value and the idle average fuel consumption value, including: when the operating state is characterized as an idle state, a preset second adjustment parameter value associated with the idle state is obtained by looking up a table based on the deviation value, the remaining fuel value and the idle average fuel consumption value.

[0097] In this specific embodiment, a second data set is established, and the second data set includes a one-to-one correspondence between the preset second adjustment parameter value and the deviation value, the remaining fuel value, and the idle average fuel consumption value. Applying the deviation value, the remaining fuel value, and the idle average fuel consumption value to the second data set can quickly obtain the corresponding preset second adjustment parameter. Not only does it save data space, but it also reduces the amount of data calculation and improves the response speed.

[0098] Step S104, obtaining a target cruising range value of the target detection cycle based on the previous target cruising range value and the preset adjustment parameter value.

[0099] In some specific embodiments, when the operating state is characterized as a driving state, obtaining the target cruising range value of the target detection cycle based on the previous target cruising range value and the preset adjustment parameter value includes:

[0100] Step S104a, obtaining the target cruising range value of the target detection cycle based on the difference between the previous target cruising range value and the preset first adjustment parameter value.

[0101] For example, display (T) = O display (T-1)-Δσ drv ; Among them, O display (T) represents the target cruising range value of the target detection cycle, display (T-1) represents the previous target cruising range value, Δσ drv is a preset first adjustment parameter value.

[0102] In some specific embodiments, when the operating state is characterized as an idle state, obtaining the target cruising range value of the target detection cycle based on the previous target cruising range value and the preset adjustment parameter value includes:

[0103] Step S104b, obtaining the target cruising range value of the target detection cycle based on the difference between the previous target cruising range value and the preset second adjustment parameter value.

[0104] For example, in, represents the target cruising range value of the target detection cycle, Odisplay (T-1) represents the previous target cruising range value, Δσ Idle Indicates the preset second adjustment parameter value.

[0105] After obtaining the target cruising range value of the target detection cycle, the target cruising range value can be displayed on the instrument panel. At the same time, the target cruising range value of the target detection cycle can be used as the next target detection cycle. When the starting cycle process ends (i.e. the vehicle is turned off), the last obtained target cruising range value is saved. When the next starting cycle process is started again, the saved target cruising range value is read and sent to ensure the continuity and accuracy of the display and control system.

[0106] In some specific embodiments, when the starting cycle process starts, before obtaining the operating status of the vehicle in the target detection cycle and the theoretical value and planned display value of the cruising range, it also includes:

[0107] Step S100-1, obtaining the initial remaining fuel amount of the cruising range, the average fuel consumption value and the initial ratio change of the alcohol fuel.

[0108] The initial remaining fuel amount refers to the remaining fuel amount detected at the beginning of the starting cycle.

[0109] The average fuel consumption value is the average fuel consumption value within a preset distance (for example, 50 km) saved at the end of the previous starting cycle.

[0110] The initial ratio change refers to the difference between the fuel ratio value detected during the previous start cycle and the fuel ratio value detected during the current start cycle. The fuel ratio value detected during the previous start cycle is stored in the vehicle before the previous start cycle ends.

[0111] Step S100-2, obtaining an initial theoretical value of the cruising range value based on the initial remaining fuel amount, the average fuel consumption value and the initial ratio change.

[0112] The initial theoretical value is the basis for obtaining the first target range value.

[0113] In some specific embodiments, the obtaining the initial theoretical value of the cruising range value based on the initial remaining fuel amount, the average fuel consumption value and the initial ratio change includes:

[0114] Step S100-2a, when the initial ratio change is within a preset normal ratio change range, an initial theoretical value of the cruising range is obtained based on a quotient of the initial remaining fuel amount and the average fuel consumption value.

[0115] When the initial ratio change is within the preset normal ratio change range, it indicates that the fuel ratio value detected during the previous starting cycle is unchanged from the fuel ratio value detected during the current starting cycle. The initial theoretical value of the cruising range is obtained by taking the quotient of the initial remaining fuel amount and the average fuel consumption value.

[0116] For example,

[0117] Among them, O calc represents the initial theoretical value, P fule Indicates the initial remaining fuel volume, A 50km Indicates the average fuel consumption of the vehicle over a distance of nearly 50 km.

[0118] In some specific embodiments, the obtaining the initial theoretical value of the cruising range value based on the initial remaining fuel amount, the average fuel consumption value and the initial ratio change includes:

[0119] Step S100-2b-1, when the initial ratio change exceeds the preset normal ratio change range, an intermediate value is obtained based on the quotient of the initial remaining fuel amount and the average fuel consumption value.

[0120] Step S100-2b-2, obtaining the initial theoretical value of the cruising range value based on the product of the intermediate value and the preset correction coefficient.

[0121] When the initial ratio change exceeds the preset normal ratio change range, it indicates that the fuel ratio value detected during the previous starting cycle has changed from the fuel ratio value detected during the current starting cycle, and the initial theoretical value of the cruising range is obtained through the initial remaining fuel, the average fuel consumption value and the preset correction coefficient.

[0122] For example,

[0123] Among them, O ca lc represents the initial theoretical value, P fule Indicates the initial remaining fuel volume, A 50km Indicates the average fuel consumption of the vehicle for nearly 50 km, K e Indicates the preset correction factor.

[0124] The preset correction coefficient is an empirical value obtained through experiments.

[0125] The initial theoretical value is obtained in this way, and similarly, the theoretical value of the cruising range within the starting cycle based on the initial theoretical value can also be obtained in this way.

[0126] like Figure 2As shown, during the starting cycle of an alcohol fuel vehicle, after the vehicle is started, oil information is obtained, and the oil information includes: the remaining fuel amount, the average fuel consumption value, and the change in the ratio of the alcohol fuel. Determine whether the change in the ratio has changed? If there is no change, the theoretical value is obtained by the quotient of the remaining fuel amount and the average fuel consumption value; if there is a change, the theoretical value is obtained by the quotient of the remaining fuel amount, the average fuel consumption value, and the preset correction coefficient. When there is a large deviation between the planned display value and the theoretical value, if the vehicle is in a driving state, the preset first adjustment parameter value is obtained based on the deviation value and the remaining fuel value, and the target cruising range value is obtained based on the difference between the previous target cruising range value and the preset first adjustment parameter value. If the vehicle is in an idling state, the preset second adjustment parameter value is obtained based on the deviation value, the remaining fuel value, and the idling average fuel consumption value, and the target cruising range value is obtained based on the difference between the previous target cruising range value and the preset second adjustment parameter value.

[0127] In the starting cycle of an alcohol fuel vehicle, the embodiment of the present application obtains the operating status of the vehicle in the target detection cycle and the theoretical value and planned display value of the cruising range; when the deviation value between the planned display value of the target detection cycle and the theoretical value is greater than the preset deviation threshold, the previous target cruising range value of the previous detection cycle immediately adjacent to the target detection cycle and the key influencing parameter value associated with the operating status are obtained; based on the deviation value and the key influencing parameter value associated with the operating status, the preset adjustment parameter value associated with the operating status is obtained; based on the previous target cruising range value and the preset adjustment parameter value, the target cruising range value of the target detection cycle is obtained. When the deviation between the planned display value and the theoretical value is large, the previous target cruising range value is adjusted by the dynamically obtained preset adjustment parameter value, so that a more accurate target cruising range value can be obtained. It is convenient for users to better plan their trips, reduce driving anxiety, and improve driving experience.
