[0055] The specific embodiments of the present application have been shown by the above-described drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the present application in any way, but to explain the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0056] The exemplary embodiments will be described in detail herein below with reference to the drawings. In the following description, the same drawings reference numerals are used to refer to elements having the same or similar functions. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0057] In the description of the embodiments of the present application, "first", "second", "third" (if any) and the like are used to distinguish similar objects, and do not necessarily indicate a particular order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments described herein can also be implemented in an order other than that illustrated or described in the present application. The terms "inner", "outer" and the like indicating the direction or positional relationship of the terms are based on the direction or positional relationship shown in the drawings, which is merely for the convenience of description, and do not indicate or imply that the device or component must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0058] In the description of the embodiments of the present application, unless otherwise specifically defined and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication between the two components inside. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0059] The fuel-saving switch, also known as a fuel-saving switch, or a multi-power fuel-saving switch, or a multi-state switch, is connected to the electronic control unit (ECU) of the vehicle through a connecting line, and is used to adjust the output power of the engine.

[0060] Taking a truck as an example, the fuel-saving switch can be installed on the instrument panel of the truck, and a plurality of gears are marked on the fuel-saving switch, such as heavy load gear, medium load gear, light load gear, and empty load gear. By rotating the rotating wheel or knob on the fuel-saving switch, the corresponding gear is selected.

[0061] In the prior art, when the vehicle is power controlled, the gear determined by the fuel-saving switch installed on the vehicle is determined. When the light load gear is selected, the output power is small to save fuel, and when the heavy load gear is selected, the output power is high to meet the power demand of the vehicle.

[0062] At present, when the vehicle is matched with the installed fuel-saving switch, a type of fuel-saving switch is usually selected according to the gear recognition voltage of the ECU which has been calibrated. The switch input voltage of this type of fuel-saving switch matches the gear recognition voltage of the ECU.

[0063] However, the above method is only applicable to a type of fuel-saving switch that matches the calibrated ECU gear recognition voltage. Different types of fuel-saving switches have different internal resistance values, and different resistance values can easily cause the switch input voltage of the fuel-saving switch to not match the gear recognition voltage. Therefore, other types of fuel-saving switches cannot be applied to the vehicle. If the same vehicle replaces a non-matching fuel-saving switch, it can easily cause the output power of the engine to not match the actual gear demand power.

[0064] For example,

[0065] Figure 1 A calibrated ECU gear recognition voltage diagram is provided for the present application, as shown in Figure 1 Suppose the calculated switch input voltage of the fuel-saving switch A at the heavy load gear is 2.5V, the switch input voltage at the medium load gear is 3.6V, and the switch input voltage at the light load gear is 4.4V.

[0066] According to Figure 1The ECU gear recognition voltage interval corresponding to the heavy load gear, the medium load gear and the light load gear of the winning calibration can be seen that 2.5V is in the ECU gear recognition voltage interval [1000mV, 2900mV] corresponding to the heavy load gear, 3.6V is in the ECU gear recognition voltage interval [3000mV, 3900mV] corresponding to the medium load gear, and 4.4V is in the ECU gear recognition voltage interval [4000mV, 4800mV] corresponding to the light load gear. The input voltage of the fuel-saving switch A matches the ECU gear recognition voltage, and the power output by the engine matches the actual gear demand power.

[0067] If the same vehicle is replaced with a non-matching fuel-saving switch B, due to the difference in resistance value of the built-in resistance of different types of fuel-saving switches, the calculated switch input voltage of the fuel-saving switch B under the heavy load gear is 4.4V, the switch input voltage under the medium load gear is 4.68V, and the switch input voltage under the light load gear is 4.78V. The three voltages under different gears are too close, and all correspond to the calibrated ECU gear recognition voltage interval [4000mV, 4800mV] corresponding to the light load gear. The input voltage of the fuel-saving switch B under different gears does not match the ECU gear recognition voltage, resulting in a mismatch between the power output by the engine and the actual gear demand power.

[0068] Alternatively, if the same vehicle is replaced with a non-matching fuel-saving switch, in order to match the input voltage of the fuel-saving switch with the ECU gear recognition voltage, it is necessary to artificially recalibrate the new ECU gear recognition voltage, i.e., one type of fuel-saving switch calibrates one ECU gear recognition voltage. The recalibration requires the vehicle to be returned to the factory for processing, which is complicated and complex, and affects the user experience.

[0069] Therefore, in view of the above technical problems in the prior art, the present application proposes a vehicle control method, device, equipment and medium for matching multiple fuel-saving switches. The switch input voltage of the fuel-saving switch of the vehicle under the current gear is obtained, and the target voltage compensation value is determined from the pre-stored correspondence between the switch input voltage and the voltage compensation value according to the switch input voltage. The ECU gear recognition voltage is obtained by adding the target voltage compensation value and the switch input voltage. By correcting the switch input voltage of the fuel-saving switch, other types of fuel-saving switches can be matched to the same vehicle. Then, according to the ECU gear recognition voltage obtained by adding the target voltage compensation value and the switch input voltage, the output power of the vehicle engine is controlled, so that the output power is more in line with the power demand of the current gear.

[0070] In order to facilitate understanding of the method of the present application, an application scenario is exemplarily provided as follows, Figure 2 An application scenario diagram is provided for the present application as follows, Figure 2As shown: including fuel-saving switch 201, connecting line 202, electronic control unit 203.

[0073] Electronic control unit 203, for obtaining switch input voltage of fuel-saving switch, determining voltage compensation value, and calculating gear recognition voltage of ECU according to switch input voltage and voltage compensation value, and controlling vehicle engine output corresponding power according to gear recognition voltage of ECU.

[0074] It can be understood that the number, form, function and interaction mode of fuel-saving switch 201, connecting line 202 and electronic control unit 203 in the application are not limited, and the gear in fuel-saving switch 202 is not limited. The above scenarios are only used for illustration, and in the specific application of the scheme, it can be set according to the actual needs.

[0075] The technical scheme of the application and how the technical scheme of the application solves the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the application will be described below with reference to the drawings.

[0076] Figure 3 A flowchart of a vehicle control method matching a plurality of fuel-saving switches is provided for the embodiments of the application. The execution subject of the method can be a vehicle terminal. The method in the embodiment can be realized by software, hardware or a combination of software and hardware. As shown in the figure, the method specifically includes the following steps: Figure 3

[0077] S301, obtaining switch input voltage of fuel-saving switch of vehicle at current gear.

[0078] A possible implementation manner:

[0079] According to the current gear, the resistance value of the fuel-saving switch connected at the current gear is determined, the switch input voltage of the fuel-saving switch at the current gear is calculated according to the preset ECU pull-up voltage value, ECU pull-up resistance value and connected resistance value, and then the switch input voltage is obtained.

[0080] Exemplarily,

[0081] ​Figure 4A A schematic diagram for obtaining the switch input voltage of the fuel-saving switch is provided in the embodiment of the present application, as shown in Figure 4A Assuming that the current gear of the vehicle is the heavy-load gear, the preset ECU pull-up voltage value is 5V, the ECU pull-up resistance value is 1.35K, and one resistance built in the fuel-saving switch is connected to the ECU in series, with a resistance value of 1.5K. Then the switch input voltage = 5V / (1.35K+1.5K) x 1.5K = 2.63V.

[0082] Figure 4B Another schematic diagram for obtaining the switch input voltage of the fuel-saving switch is provided in the embodiment of the present application, as shown in Figure 4B Assuming that the current gear of the vehicle is the medium-load gear, the preset ECU pull-up voltage value is 5V, the ECU pull-up resistance value is 1.35K, and two resistances built in the fuel-saving switch are connected to the ECU in series, with resistance values of 1.5K and 2.7K respectively. Then the switch input voltage = 5V / (1.35K+1.5K+2.7K) x (1.5K+2.7K) = 3.78V.

[0083] Figure 4C Still another schematic diagram for obtaining the switch input voltage of the fuel-saving switch is provided in the embodiment of the present application, as shown in Figure 4C Assuming that the current gear of the vehicle is the medium-load gear, the preset ECU pull-up voltage value is 5V, the ECU pull-up resistance value is 1.35K, and three resistances built in the fuel-saving switch are connected to the ECU in series, with resistance values of 1.5K, 2.7K and 5.6K respectively. Then the switch input voltage = 5V / (1.35K+1.5K+2.7K+5.6K) x (1.5K+2.7K+5.6K) = 4.39V.

[0084] The number of built-in resistances in the fuel-saving switch connected to the ECU under different gears is determined by the principle of the fuel-saving switch, which is not the focus of the present application, and specific details can be found in relevant technologies, which will not be described herein.

[0085] It can be understood that the above examples are only for illustration, and do not limit the present application.

[0086] S302, according to the switch input voltage, determining the target voltage compensation value from the corresponding relationship between the switch input voltage and the voltage compensation value stored in advance.

[0087] In the embodiment, the corresponding relationship between the switch input voltage and the voltage compensation value is established in advance and stored.

[0088] The corresponding relationship can be stored in a form of a MAP chart, and the corresponding relationship can be referred to as a voltage configuration table. In the MAP chart, voltage compensation values corresponding to different gear positions and different fuel-saving switch input voltages are pre-stored, the horizontal coordinate is gear position information, and the vertical coordinate is a switch input voltage of the fuel-saving switch.

[0089] Therefore, after obtaining the switch input voltage of the fuel-saving switch through step S301, the corresponding voltage compensation value of the switch input voltage can be determined according to the MAP chart.

[0090] S303, add the switch input voltage and the target voltage compensation value to obtain a gear recognition voltage of the electronic control unit ECU.

[0091] An exemplary,

[0092] Suppose that the switch input voltage is 0.8V in the heavy load gear, and the target voltage compensation value determined from the MAP chart is 1V. The switch input voltage is added to the target voltage compensation value, that is, 0.8+1=1.8V, and then 1.8V is the gear recognition voltage of the electronic control unit ECU in the heavy load gear.

[0093] Suppose that the switch input voltage is 1.1V in the medium load gear, and the target voltage compensation value determined from the MAP chart is 1.5V. The switch input voltage is added to the target voltage compensation value, that is, 1.1+1.5=2.6V, and then 2.6V is the gear recognition voltage of the electronic control unit ECU in the medium load gear.

[0094] Suppose that the switch input voltage is 1.4V in the light load gear, and the target voltage compensation value determined from the MAP chart is 2.5V. The switch input voltage is added to the target voltage compensation value, that is, 1.4+2.5=3.9V, and then 3.9V is the gear recognition voltage of the electronic control unit ECU in the light load gear.

[0095] S304, according to the gear recognition voltage of the ECU, control the vehicle engine to output power corresponding to the current gear.

[0096] A possible implementation is:

[0097] According to the gear recognition voltage of the ECU, determine a target voltage interval in which the recognition voltage is located in a preset voltage interval, and according to gear information corresponding to the target voltage interval, determine a power control curve corresponding to the gear information, and then according to the power control curve, control the vehicle engine to output power corresponding to the current gear.

[0098] Figure 5 A schematic diagram of a preset ECU gear recognition voltage interval in different gears provided by the embodiment of the application is as follows: Figure 5As shown, assuming that the obtained gear recognition voltage of the ECU is 1.5V, from Figure 5 It can be determined that the interval in which 1.5 is located is the [1000mV, 2900mV] interval, which belongs to the heavy load gear state, and then the power control curve corresponding to the heavy load gear, for example, the external characteristic curve, is used to control the vehicle engine to output the power corresponding to the heavy load gear.

[0099] Correspondingly, assuming that the obtained gear recognition voltage of the ECU is 3.5V, from Figure 5 It can be determined that the interval in which 3.5 is located is the [3000mV, 3900mV] interval, which belongs to the medium load gear state, and then the power control curve corresponding to the medium load gear is used to control the vehicle engine to output the power corresponding to the medium load gear.

[0100] Correspondingly, assuming that the obtained gear recognition voltage of the ECU is 4.5V, from Figure 5 It can be determined that the interval in which 4.5 is located is the [4000mV, 4800mV] interval, which belongs to the light load gear state, and then the power control curve corresponding to the light load gear is used to control the vehicle engine to output the power corresponding to the medium load gear.

[0101] In the above embodiment of the present application, by obtaining the switch input voltage of the fuel-saving switch of the vehicle at the current gear, the target voltage compensation value is determined from the corresponding relationship between the switch input voltage and the voltage compensation value which is stored in advance. Then, the switch input voltage and the target voltage compensation value are added to obtain the gear recognition voltage of the electronic control unit (ECU), and finally the power corresponding to the current gear is output by the vehicle engine according to the gear recognition voltage of the ECU. The present application can be applied to multiple types of fuel-saving switches, so that the power output by the vehicle engine meets the power demand of the current gear, better meeting the driving demand of the vehicle.

[0102] Further, on the basis of the above embodiment, the vehicle control method of the present application which matches multiple fuel-saving switches is described in detail in the following embodiment.

[0103] In order to facilitate understanding of the present embodiment, the principle that the present application can match multiple fuel-saving switches is first described.

[0104] Taking the fuel-saving switch configured with three gears as an example, they are heavy load gear, medium load gear and light load gear. Although the resistance values of the resistors built in different types of fuel-saving switches are different, the switch output voltage U1 at the heavy load gear is the smallest, the switch output voltage U2 at the medium load gear is the second, and the switch output voltage U3 at the light load gear is the largest, i.e. U1<U2<U3.

[0105] Example 1,

[0106] Assuming that the fuel-saving switch is built-in with 3 resistors, each resistor has a resistance of aKΩ, the ECU pull-up voltage value is 5V, and the ECU pull-up resistance value is 2KΩ. Under heavy load gear, one built-in resistor of the fuel-saving switch is connected in series with the ECU, under medium load gear, two built-in resistors of the fuel-saving switch are connected in series with the ECU, and under light load gear, three built-in resistors of the fuel-saving switch are connected in series with the ECU.

[0107] Then the switch output voltage U1 under heavy load gear is U1=5 / (2+a)×a.

[0108] Then the switch output voltage U2 under medium load gear is U2=5 / (2+a+a)×2a.

[0109] Then the switch output voltage U3 under light load gear is U3=5 / (2+a+a+a)×3a.

[0110] From the above formula, it can be concluded that U1<U2<U3.

[0111] Example 2,

[0112] Assuming that the fuel-saving switch is built-in with 3 resistors, each resistor has a resistance of aKΩ, bKΩ and cKΩ, because the arrangement of different resistors under different gears is different, the switch output voltage under different gears is also different.

[0113] There are 6 arrangements of three resistors in the fuel-saving switch, which are as follows:

[0114] Arrangement 1: Resistor 1 resistance aKΩ, resistor 2 resistance bKΩ, resistor 3 resistance cKΩ. Arrangement 2: Resistor 1 resistance aKΩ, resistor 2 resistance cKΩ, resistor 3 resistance bKΩ. Arrangement 3: Resistor 1 resistance cKΩ, resistor 2 resistance aKΩ, resistor 3 resistance bKΩ. Arrangement 4: Resistor 1 resistance cKΩ, resistor 2 resistance bKΩ, resistor 3 resistance aKΩ. Arrangement 5: Resistor 1 resistance bKΩ, resistor 2 resistance cKΩ, resistor 3 resistance aKΩ.

[0115] Arrangement 6: Resistor 1 resistance bKΩ, resistor 2 resistance aKΩ, resistor 3 resistance cKΩ.

[0116] For example, assuming a=1, b=2, c=3,

[0117] Arrangement 1:

[0118] Then the switch output voltage U1 under heavy load gear is U1=5 / (2+a)×a=1.67.

[0119] The switch output voltage U2 in the medium load position is U2=5 / (2+a+b) x (a+b)=3.33.

[0120] The switch output voltage U3 in the light load position is U3=5 / (2+a+b+c) x (a+b+c)=3.75.

[0121] Arrangement mode 2:

[0122] The switch output voltage U1 in the heavy load position is U1=5 / (2+a) x a=1.67.

[0123] The switch output voltage U2 in the medium load position is U2=5 / (2+a+b) x (a+b)=3.33.

[0124] The switch output voltage U3 in the light load position is U3=5 / (2+a+b+c) x (a+b+c)=3.75.

[0125] Arrangement mode 3:

[0126] The switch output voltage U1 in the heavy load position is U1=5 / (2+a) x a=3.

[0127] The switch output voltage U2 in the medium load position is U2=5 / (2+a+b) x (a+b)=3.33.

[0128] The switch output voltage U3 in the light load position is U3=5 / (2+a+b+c) x (a+b+c)=3.75.

[0129] Arrangement mode 4:

[0130] The switch output voltage U1 in the heavy load position is U1=5 / (2+a) x a=3.

[0131] The switch output voltage U2 in the medium load position is U2=5 / (2+a+b) x (a+b)=3.57.

[0132] The switch output voltage U3 in the light load position is U3=5 / (2+a+b+c) x (a+b+c)=3.75.

[0133] Arrangement mode 5:

[0134] The switch output voltage U1 in the heavy load position is U1=5 / (2+a) x a=2.5.

[0135] The switch output voltage U2 in the medium load position is U2=5 / (2+a+b) x (a+b)=3.57.

[0136] The switch output voltage U3 in the light load position is U3=5 / (2+a+b+c) x (a+b+c)=3.75.

[0137] Arrangement 6:

[0181] Therefore, different types of fuel-saving switches have the smallest switch output voltage under the heavy load gear, the second smallest under the medium load gear, and the largest under the light load gear.

[0182] Therefore, when the user manually swings the three gears of the fuel-saving switch, according to the size relationship of the received switch output voltage, the switch output voltage corresponding to different gears can be determined. For example, the received switch output voltages are 2.1V, 3.6V, and 2.8V, respectively, and it can be considered that 2.1V corresponds to the heavy load gear, 2.8V corresponds to the medium load gear, and 3.6V corresponds to the light load gear.

[0183] Further, it is assumed that the correspondence between the pre-stored switch input voltage and the voltage compensation value, i.e. the MAP table, is as shown in Table 1:

[0184] Table 1

[0185]

[0186] The manner of establishing the correspondence between the switch input voltage and the voltage compensation value can be:

[0187] The ECU expected recognition voltage preset at different gears and the multiple switch input voltages of the fuel-saving switch at different gears are obtained, and the multiple switch input voltages are divided into multiple switch input voltage intervals. For any one switch input voltage interval, the voltage compensation value corresponding to the different gears of the switch input voltage interval is calculated according to the ECU expected recognition voltage preset at different gears and the switch input voltage in the switch input voltage interval, and the correspondence between the switch input voltage and the voltage compensation value is established according to the voltage compensation value at different gears corresponding to each switch input voltage interval and the multiple switch input voltage intervals.

[0188] It can be understood that the data in Table 1 is only used for illustration and does not limit the present application.

[0189] Further, the target voltage compensation value is determined according to the switch input voltage from the pre-stored correspondence between the switch input voltage and the voltage compensation value. Figure 6 A flowchart of a method for determining a target voltage compensation value provided by the embodiment of the present application is shown in Figure 6 The method comprises the following steps:

[0190] S601. Determine the target switch input voltage interval in which the switch input voltage is located from the pre-set switch input voltage interval according to the switch input voltage.

[0191] S602. Determine the voltage compensation value corresponding to the target switch input voltage interval as the first voltage compensation value.

[0192] S603. Determine the target gear in which the vehicle is currently located according to the switch input voltage.

[0193] S604. Determine the voltage compensation value corresponding to the target gear as the second voltage compensation value.

[0194] S605. Determine the voltage compensation value of the intersection of the first voltage compensation value and the second voltage compensation value as the target voltage compensation value.

[0195] Exemplarily,

[0196] If the received switch output voltages are 2.1V, 3.6V and 2.8V respectively, it can be determined from Table 1 that 2.1V is in the Y5 interval, 3.6V is in the Y8 interval and 2.8V is in the Y6 interval. According to the foregoing description, it can be determined that 2.1V corresponds to the heavy load gear, 2.8V corresponds to the medium load gear and 3.6V corresponds to the light load gear.

[0197] According to the voltage compensation value of the intersection of the target switch input voltage interval and the target gear, it can be determined that the voltage compensation value corresponding to 2.1V is -0.5, the voltage compensation value corresponding to 2.8V is -0.5 and the voltage compensation value corresponding to 3.6V is 0.

[0198] The switch output voltage 2.1V is added to the voltage compensation value -0.5 to obtain the gear recognition voltage of the ECU, which is 1.6V. The switch output voltage 2.8V is added to the voltage compensation value -0.5 to obtain the gear recognition voltage of the ECU, which is 2.3V. The switch output voltage 3.6V is added to the voltage compensation value 0 to obtain the gear recognition voltage of the ECU, which is 3.6V.

[0199] If the received switch output voltages are 0.8V, 1.1V and 1.4V respectively, it can also be determined from Table 1 that 0.8V is in the Y2 interval, 1.1V is in the Y3 interval and 1.4V is in the Y3 interval. According to the foregoing description, it can be determined that 0.8V corresponds to the heavy load gear, 1.1V corresponds to the medium load gear and 1.4V corresponds to the light load gear.

[0200] According to the voltage compensation value of the intersection of the target switch input voltage interval and the target gear, it can be determined that the voltage compensation value corresponding to 0.8V is 1, the voltage compensation value corresponding to 1.1V is 1.5 and the voltage compensation value corresponding to 1.4V is 2.5.

[0201] The switch output voltage 0.8V is added to the voltage compensation value 1 to obtain the gear recognition voltage of the ECU, which is 1.8V. The switch output voltage 1.1V is added to the voltage compensation value 1.5 to obtain the gear recognition voltage of the ECU, which is 2.6V. The switch output voltage 1.4V is added to the voltage compensation value 2.5 to obtain the gear recognition voltage of the ECU, which is 3.9V.

[0202] It should be noted that if the size of the switch output voltage is at the interval end point of the switch input voltage in Table 1, for example, the switch output voltage 1.5V is at the upper limit end point of the Y3 interval and at the lower limit end point of the Y4 interval, the voltage compensation value corresponding to the Y3 interval and the voltage compensation value corresponding to the Y4 interval can be determined at the same time. The value in specific application can be determined according to a preset value algorithm or according to user indication information, which is not limited in the present application.

[0203] In the above embodiments of the present application, no matter what kind of fuel-saving switch is used, no matter what resistance value is used in the fuel-saving switch, the voltage compensation value can be determined according to the obtained switch input voltage and the corresponding relationship between the switch input voltage and the voltage compensation value stored in advance, and then the voltage compensation value is added to the switch input voltage to obtain the gear recognition voltage of the ECU, and the engine is controlled to output corresponding power according to the gear recognition voltage of the ECU, so that the output power meets the power required by the current gear and meets the driving demand of the vehicle.

[0204] The vehicle control method provided by the present application can match various fuel-saving switches. If the fuel-saving switch is affected by temperature during use, the switch input voltage changes from the initial 0.8V, 1.1V, 1.4V to 1.6V, 2.7V, 3.6V, but 1.6V still corresponds to the heavy load gear, 2.7V still corresponds to the medium load gear, and 3.6V still corresponds to the light load gear. The initial switch input voltage 0.8V corresponds to the heavy load gear, 1.1V corresponds to the medium load gear, and 1.4V corresponds to the light load gear. This is because the switch input voltage under the heavy load gear is less than that under the medium load gear, and the switch input voltage under the medium load gear is less than that under the light load gear.
