Description

Technical Field

[0001] The present disclosure relates to the field of vehicles, and in particular to a method, device, medium and vehicle for determining the fuel level of a vehicle. Background Art

[0002] Vehicles are a common means of transportation in people's daily lives. Most vehicle fuel tanks are saddle-shaped straddle-type fuel tanks. The oil float in the fuel tank can only measure the amount of fuel in the vertical height direction. The resistance value of the oil float will change with the fluctuation of the liquid level in the fuel tank. Different resistance values ​​correspond to different remaining fuel amounts. When the vehicle is driving on a road with a large slope (such as uphill sections, downhill sections) or a bumpy road, the oil float rises or falls sharply, causing errors in the calculation of the vehicle's remaining fuel, resulting in abnormal display of the remaining fuel obtained by the user, affecting the user experience. In order to accurately display the remaining fuel, it is necessary to make corrections in combination with the vehicle's tilt parameters.

[0003] CN110514268A discloses a method for correcting the oil volume data obtained by the oil float by using the body tilt angle data obtained by the body gyroscope or the body tilt sensor and combining the body tilt angle data. However, this technical solution still has the following problems:

[0045] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0047] Figure 1 The figure is a flow chart of a method for determining the fuel level of a vehicle according to an exemplary embodiment.

[0048] Figure 2 The figure is a block diagram of a device for determining the fuel level of a vehicle according to an exemplary embodiment.

[0049] Figure 3 is a block diagram of a vehicle according to an exemplary embodiment. DETAILED DESCRIPTION

[0050] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0051] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0052] Figure 1 FIG. 1 is a flow chart of a method for determining the fuel level of a vehicle according to an exemplary embodiment. Figure 1 As shown, the method includes the following steps.

[0053] In step S101, the resistance value of the vehicle oil float is obtained.

[0054] The resistance value of the oil float changes with the change of the liquid level in the oil tank, and different resistance values ​​correspond to different remaining oil amounts.

[0055] In step S102, the oil quantity measurement value is determined according to the resistance value at the current moment.

[0056] The oil quantity measurement value is the oil quantity value determined at the current moment according to the resistance value of the oil float obtained. For example, the corresponding relationship between the resistance value and the oil quantity measurement value can be pre-stored. The oil quantity measurement value corresponding to the resistance value at the current moment is found in the corresponding relationship as the determined oil quantity measurement value.

[0057] In step S103, the tilt angle of the vehicle is determined according to the resistance value at the current moment and the resistance value at the previous moment.

[0058] In the related art, a body gyroscope or a body tilt sensor is usually installed on the vehicle body, and the vehicle tilt angle is obtained by using the body gyroscope or the body tilt sensor. However, the fuel tank of the vehicle is usually installed at a specific position of the vehicle body, and there is a difference in the position angle between the vehicle body and the fuel tank. If the vehicle tilt angle obtained by the body gyroscope or the body tilt sensor at the vehicle body is different from the actual tilt angle of the fuel tank, the consistency is poor, and the accuracy of the determined tilt angle data is low.

[0059] When a vehicle is traveling on a sloped road or a rugged road, the inclination angle of the vehicle body changes greatly, and the liquid level in the fuel tank rises or falls, which causes the resistance value of the oil float to change greatly. However, in fact, the amount of oil is not consumed much. If the oil amount measurement value determined by the resistance value of the oil float at the current moment is directly used as the actual amount of oil in the vehicle, the actual amount of oil will have a large error. When the vehicle is traveling on a flat road, the liquid level in the fuel tank is in a slowly decreasing state, the liquid level changes little, and the resistance value of the oil float changes little before and after. In this scheme, the change in the resistance value of the oil float at the current moment and the resistance value of the oil float at the previous moment can characterize the change in the liquid level in the fuel tank, thereby reflecting the ruggedness of the road surface where the vehicle is currently located and the actual inclination angle of the fuel tank. Therefore, the inclination angle of the vehicle (fuel tank) can be determined according to the resistance value at the current moment and the resistance value at the previous moment.

[0060] In step S104, the actual fuel level of the vehicle is determined based on the determined tilt angle and the fuel level measurement value.

[0061] The oil level measurement value is the oil level value determined based on the oil float resistance value at the current moment when the oil level is not calibrated. After the vehicle's tilt angle is determined, the oil level measurement value determined under the vehicle's tilt condition is calibrated in combination with the vehicle's tilt angle. The calibrated oil level value is the actual oil level of the vehicle.

[0062] Through the above technical solution, the remaining oil volume of the vehicle will not change dramatically when it is driving normally on a flat road. The change in the resistance value of the oil float at the current moment and the resistance value at the previous moment can characterize the change in the oil tank liquid level. The change in the oil tank liquid level is related to the bumps of the road the vehicle is currently on (the drastic change in the resistance value is caused by the bumps of the road the vehicle is on). Therefore, the vehicle's tilt angle can be reliably and accurately determined based on the resistance value at the current moment and the resistance value at the previous moment, and there is no need to set a body gyroscope or body tilt sensor in the fuel tank, and there is no need to increase the cost of the entire vehicle. The obtained oil volume measurement value is calibrated in combination with the vehicle's tilt angle, and the calibrated measurement value is used as the actual oil volume. The oil volume correction display result is highly accurate and the user experience is good.

[0063] In another embodiment, the above-mentioned determining the tilt angle of the vehicle according to the resistance value at the current moment and the resistance value at the previous moment includes:

[0064] Determine the current tank liquid level height according to the current resistance value;

[0065] Determine the oil tank liquid level height at the last moment according to the resistance value at the last moment;

[0066] Determine the height difference between the fuel tank liquid level at the previous moment and the fuel tank liquid level at the current moment;

[0067] The tilt angle of the vehicle is determined based on the height difference and the crank length of the oil float.

[0068] The oil tank liquid level height is related to the resistance value of the oil float. For example, the correspondence between the oil tank liquid level height and the resistance value of the oil float can be pre-stored. After determining the resistance value of the oil float at the current moment and the resistance value of the oil float at the previous moment, the oil tank liquid level height corresponding to the resistance value at the current moment and the oil tank liquid level height corresponding to the resistance value at the previous moment can be found from the predetermined correspondence.

[0069] The height difference between the oil tank level at the last moment and the oil tank level at the current moment can characterize the height change of the oil tank level, thereby intuitively reflecting the degree of inclination of the vehicle. Therefore, the inclination angle of the vehicle can be determined according to the height difference between the oil tank level at the last moment and the oil tank level at the current moment, and the crank length of the oil float. For example, the corresponding relationship between the height difference between the oil tank level at the last moment and the oil tank level at the current moment, the crank length of the oil float and the inclination angle of the vehicle can be stored in advance, and the inclination angle of the vehicle can be determined by looking up a table. For another example, the inclination angle of the vehicle can also be calculated according to the height difference between the oil tank level at the last moment and the oil tank level at the current moment, and the crank length of the oil float.

[0070] In this embodiment, the height difference between the fuel tank liquid level height at the previous moment and the fuel tank liquid level height at the current moment can represent the height change of the fuel tank liquid level before and after the moment, thereby intuitively reflecting the degree of inclination of the vehicle. The inclination angle of the vehicle is determined in combination with the height difference of the fuel tank liquid level before and after the moment and the crank length of the oil float, thereby further improving the accuracy of the inclination angle of the vehicle.

[0071] In yet another embodiment, the above-mentioned determining the tilt angle of the vehicle according to the height difference and the crank length of the oil float includes:

[0072] The vehicle's tilt angle is calculated using the following formula:

[0073]

[0074] Among them, θ represents the tilt angle of the vehicle; FL represents the crank length of the oil float; H0 represents the oil tank liquid level height at the previous moment; H1 represents the oil tank liquid level height at the current moment; H0-H1 represents the height difference.

[0075] After determining the height difference between the fuel tank liquid level at the previous moment and the fuel tank liquid level at the current moment, the tilt angle of the vehicle can be calculated according to the above formula (1).

[0076] In this embodiment, the inclination angle of the vehicle is calculated using a formula, which has high accuracy and fast calculation speed.

[0077] In another embodiment, the above-mentioned determining the tilt angle of the vehicle according to the resistance value at the current moment and the resistance value at the previous moment further includes:

[0078] Determine the resistance value difference between the resistance value at the previous moment and the resistance value at the current moment;

[0079] The inclination angle of the vehicle corresponding to the resistance value difference is found out from a predetermined corresponding relationship as the determined inclination angle, wherein the corresponding relationship includes a corresponding relationship between the resistance value difference and the inclination angle.

[0080] The change in the resistance of the oil float is related to the change in the height of the liquid level in the fuel tank. The difference in resistance between the resistance of the oil float at the previous moment and the resistance of the oil float at the current moment can characterize the change in the height of the fuel tank liquid level, thereby intuitively reflecting the degree of tilt of the vehicle. The greater the difference in resistance between the resistance of the oil float at the previous moment and the resistance of the oil float at the current moment, the more drastic the change in the height of the fuel tank liquid level before and after, and the greater the degree of tilt of the vehicle; the smaller the difference in resistance between the resistance of the oil float at the previous moment and the resistance of the oil float at the current moment, the slighter the change in the height of the fuel tank liquid level before and after, and the smaller the degree of tilt of the vehicle.

[0081] The predetermined corresponding relationship can be preset by the designer based on experience or test results. After determining the resistance difference between the resistance value of the oil float at the last moment and the resistance value of the oil float at the current moment, the corresponding tilt angle can be found from the predetermined corresponding relationship.

[0082] In this embodiment, the tilt angle of the vehicle is determined by a simple table lookup method, which is simple and has a fast calculation speed.

[0083] In yet another embodiment, determining the actual fuel level of the vehicle according to the determined tilt angle and the fuel level measurement value includes:

[0084] An actual fuel level of the vehicle is determined based on the determined tilt angle, predetermined fuel level calibration parameters, and the fuel level measurement.

[0085] The predetermined oil volume calibration parameters can be pre-calibrated by the designer based on experiments. The calibration process is as follows:

[0086] Table 1

[0087] Tilt Angle Oil quantity measurement Actual oil volume Oil quantity error 5° 50L 52L 2L 10° 50L 55L 5L 15° 50L 59L 9L

[0088] First, the oil volume measurement values, actual oil volume and oil volume error at different tilt angles are obtained and recorded in Table 1. Then, the ratio of each tilt angle in Table 1 to its corresponding oil volume error can be calculated. That is: k1 = 2L / 5°; k2 = 5L / 10°; k3 = 9L / 15°.

[0089] The oil quantity calibration parameter is the fitting result of k1, k2, and k3, which is 0.4L / °.

[0090] After determining the tilt angle of the vehicle, the current fuel level measurement value of the vehicle can be calibrated in combination with the tilt angle of the vehicle and predetermined fuel level calibration parameters to determine the actual fuel level of the vehicle (the calibrated fuel level measurement value).

[0091] In this embodiment, the oil quantity measurement value is calibrated in combination with the determined tilt angle and the predetermined oil quantity calibration parameter, and the actual oil quantity after calibration eliminates the error caused by the vehicle tilt, and the actual oil quantity determined is highly accurate.

[0092] In yet another embodiment, determining the actual fuel level of the vehicle according to the determined tilt angle, the predetermined fuel level calibration parameter and the fuel level measurement value comprises:

[0093] Calculate the actual fuel volume of the vehicle according to the following formula:

[0094] V1=V0+K×θ (2)

[0095] Wherein, V1 represents the actual fuel volume of the vehicle; V0 represents the fuel volume measurement value; K represents the predetermined fuel volume calibration parameter; and θ represents the determined tilt angle.

[0096] After determining the tilt angle of the vehicle and the fuel level measurement value at the current moment, the actual fuel level of the vehicle can be calculated using the above formula (2).

[0097] In this embodiment, the above formula (2) is used to calculate the actual fuel volume of the vehicle, which has high accuracy and fast calculation speed.

[0098] In yet another embodiment, the above method further includes:

[0099] outputting the determined actual oil quantity; and / or,

[0100] When the actual oil level is less than the preset oil level threshold, an alarm message is output.

[0101] After the actual fuel level of the vehicle is determined, the determined actual fuel level can be output. For example, the actual fuel level of the vehicle can be output on the central control screen of the vehicle.

[0102] The predetermined fuel level threshold can be pre-set by the designer or the driver, for example, it can be 10L. When the actual fuel level of the vehicle is less than the predetermined fuel level threshold, the remaining fuel level of the vehicle is low, the remaining cruising range is short, and an alarm message needs to be output to remind the driver. Exemplarily, the alarm message can be output in the form of text and / or sound. For example, a pop-up message "The vehicle has little fuel left, please refuel in time!" can be controlled to be output on the central control screen of the vehicle. The speaker inside the vehicle can also be controlled to output a voice prompt "The vehicle has little fuel left, please refuel in time".

[0103] In this embodiment, the actual oil level is output to facilitate the driver to check in time, and when the actual oil level is less than the predetermined oil level threshold, the output alarm message can remind the driver in time and facilitate the taking of corresponding measures, which provides a good user experience.
