Description

Technical Field

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

[0002] With the popularization of electric vehicles and the expansion of the user scale, the performance of electric vehicles has attracted more and more attention from vehicle manufacturers and users. In particular, the mileage that an electric vehicle can still travel after driving for a certain period of time or a certain mileage. For vehicle manufacturers, the available mileage is a warranty commitment for the vehicle. For users, the available mileage is the main reference for judging the vehicle performance and driving experience. In practical applications, the available mileage of an electric vehicle is mainly determined by the health state of the electric vehicle battery pack.

[0003] In the prior art, the calculation of the available mileage of an electric vehicle in the remaining life cycle is generally as follows: obtaining the decline rate of the health state of the battery pack and the mileage corresponding to the decline rate, and calculating the mileage that the electric vehicle can still travel in the remaining life cycle by determining the decline rate that the health state of the battery pack can still decline. That is, the decline rate of the health state of the battery pack and the corresponding mileage are in a proportional relationship.

[0004] However, after an electric vehicle is used for a period of time, there is an irreversible attenuation process in the battery pack capacity, that is, the capacity of the battery pack tends to become smaller with the number of uses. At different health states, the capacity of the battery pack is different. Therefore, the available mileage determined by the proportional relationship between the decline rate of the health state of the battery pack and the corresponding mileage will have inaccurate problems.

[0065] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0066] First, the professional terms and their abbreviations involved in the embodiments of the present application are introduced:

[0067] State of Health (SOH): The percentage of the current capacity of the battery to the factory capacity, that is, the aging degree of the battery.

[0068] Before introducing the embodiments of the present application, the background technology of the present application is first explained.

[0069] As electric vehicles account for an increasing share of the vehicle market, users and vehicle manufacturers have higher and higher requirements for the performance of electric vehicles. One of the main performance indicators of a vehicle is the remaining mileage of an electric vehicle during its life cycle. For users, real-time knowledge of the remaining mileage of an electric vehicle during its life cycle can help them adjust bad driving habits in a timely manner and slow down the natural decay trend of the vehicle. For vehicle manufacturers, knowing the remaining mileage of an electric vehicle during its life cycle can help them remind users of bad vehicle use and avoid making wrong warranty promises to users after the vehicle is sold, which would affect their own interests.

[0070] The remaining life cycle mileage of an electric vehicle is largely determined by the battery pack inside the vehicle. In the prior art, the calculation of the remaining life cycle mileage of a vehicle can be achieved by the following method:

[0071] During the life cycle of a vehicle, the extent to which the battery pack's health status decreases in different health states is certain to the mileage of the corresponding electric vehicle, that is, it is believed that the extent to which the battery pack's health status decreases is proportional to the corresponding mileage. For example, if the battery pack's health status decreases from 100% to 95%, and the electric vehicle has a mileage of 40,000 kilometers, then if it decreases from 95% to 80%, the electric vehicle can still travel 120,000 kilometers.

[0072] However, as electric vehicles continue to run, the capacity of the battery pack of electric vehicles also decays accordingly. Therefore, the above calculation method is not accurate, and the remaining mileage of the electric vehicle in its life cycle is too large. In other words, it cannot guarantee that when the health status of the battery pack drops to 80%, the electric vehicle can still travel 120,000 kilometers. The conclusion drawn by this method will cause vehicle manufacturers to make wrong warranty promises to buyers and will make the user's driving experience worse.

[0073] In response to the above problems, the present application provides a vehicle mileage determination method, which obtains the mileage of the vehicle in a first time period, determines the first state information of the vehicle's power supply at the start time and the second state information at the end time according to the start time and end time of the preset time period, and determines the mileage that the vehicle can travel within the remaining life cycle according to the mileage, the first state information, the second state information, and the third state information of the power supply at the end of the vehicle life. In this technical solution, by obtaining relevant information of the vehicle, the mileage that the vehicle can travel within the remaining life cycle is determined more accurately.

[0074] It can be understood that in the embodiments of the present application, if the vehicle is an electric vehicle, the power source in the vehicle is a rechargeable battery. Exemplarily, the power source is a battery pack. The following embodiments will take the battery pack as the power source for a lower-level description. It should be noted that the vehicle is not limited to electric vehicles, but can also be a hybrid vehicle or other vehicles, as long as the vehicle can determine the remaining driving mileage within the remaining life cycle through the technical solutions provided in the embodiments of the present application.

[0075] Next, the technical solutions of the present application will be described in detail through specific embodiments. It should be noted that these specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0076] Figure 1 It is a flowchart of a method for determining the driving mileage of a vehicle provided in Embodiment 1 of the present application. As Figure 1 shown, the method may include the following steps:

[0077] S101. Obtain the driving mileage of the vehicle within the first time period.

[0078] Exemplarily, after the vehicle has been running for a period of time, if it is necessary to determine the mileage that can still be driven within its life cycle, it is first necessary to determine a period of time it has traveled before, which is called the first time period, and obtain the driving mileage within this first time period.

[0079] Exemplarily, the first time period is any period of time within the entire life cycle of the vehicle.

[0080] Specifically, the first time period is represented by T, and the selection criterion for T is that the health state of the battery pack changes within T, and this change does not include the situation where the vehicle is left unused for a long time, the available capacity of the battery pack drops suddenly, and the changes in the health state caused by other abnormal uses.

[0081] S102. Determine the first state information of the vehicle's power source at the start time and the second state information at the end time according to the start time and the end time of the first time period.

[0082] Exemplarily, when the vehicle determines the first time period it has traveled before, it first determines the start time and the end time of the first time period, and then determines the health state information of the power source at the start time based on a preset method, denoted as the first state information, and determines the health state information of the power source at the end time, denoted as the second state information.

[0083] Optionally, the end time of the first time period can be the current time, and the second state information is also the health state information of the power source in the vehicle at the current time.

[0084] Optionally, as the vehicle driving mileage increases, the capacity of the vehicle power supply will decrease accordingly. Therefore, the value of the first state information should be greater than the value of the second state information.

[0085] S103. Determine the remaining drivable mileage of the vehicle within the remaining life cycle according to the driving mileage, the first state information, the second state information, and the third state information of the power supply at the end of the vehicle life.

[0086] Exemplarily, the third state information is the health state information of the power supply at the end of the vehicle life, that is, the percentage of the power supply capacity at the end of the vehicle life to the factory capacity, and the size of this value is determined by the vehicle manufacturer and market rules.

[0087] Specifically, the vehicle can determine the power supply attenuation information within the first time period according to the first state information and the second state information, and can determine the power supply attenuation information of the vehicle within the remaining life cycle according to the second state information and the third state information. Finally, according to the driving mileage within the first time period, the power supply attenuation information within the first time period, and the power supply attenuation information of the vehicle within the remaining life cycle, calculate the remaining drivable mileage of the vehicle.

[0088] Optionally, after the vehicle determines the remaining drivable mileage, it can be sent to the user terminal or displayed on the vehicle display screen to prompt the user to pay attention to the driving habit in real time and change the original poor driving conditions. This is only an example here, and there is no specific limitation on the prompting method.

[0089] Exemplarily, according to the association relationship between the power supply state information preset in the vehicle and the vehicle driving mileage, obtain the first state information, the second state information, and the third state information, where the association relationship is stored in any one of the following forms:

[0090] Vehicle maintenance guide and maintenance report, vehicle user manual, remote monitoring data, power supply life data, and power supply detection report.

[0091] Exemplarily, after the vehicle starts on the road, as the vehicle driving mileage changes, the vehicle power supply state information also changes accordingly. The vehicle obtains the first state information, the second state information, and the third state information according to the association relationship between the power supply state information pre-stored in the vehicle and the vehicle driving mileage. Among them, the association relationship between the vehicle power supply state information and the vehicle driving mileage can be obtained from any one of the following forms:

[0092] Vehicle use and maintenance guide, user manual, vehicle maintenance report provided by the 4S store of the corresponding brand's automobile sales service, remote monitoring data pushed by the corresponding brand's vehicle factory, cell life data issued by the cell manufacturer, and battery pack detection report issued by the corresponding brand.

[0093] The method for determining the vehicle driving mileage provided in this embodiment enables the vehicle to obtain the start time and end time of the first time period based on the driving mileage within the first time period, determine the first state information, the second state information, and the third state information, and finally determine the remaining drivable mileage of the vehicle during its remaining life cycle. To a certain extent, it more accurately determines the remaining drivable mileage of the vehicle during its remaining life cycle and provides it to the user for subsequent reference, prompting the user to pay attention to bad driving habits.

[0094] Figure 2 It is a flowchart of the method for determining the vehicle driving mileage provided in the second embodiment of this application. As Figure 2 shown, the above S103 can be implemented through the following steps:

[0095] S201. Determine the first coefficient of the power supply within the first time period according to the first state information and the second state information.

[0096] Exemplarily, based on the first state information and the second state information, the vehicle determines the first coefficient of the power supply within the first time period, and this first coefficient is the intermediate value of the first state information and the second state information.

[0097] Specifically, the first state information is represented by SOH1, the second state information is represented by SOH2, and the first coefficient is represented by k1, then k1 = (SOH1 + SOH2) / 2.

[0098] S202. Determine the second coefficient of the power supply during the remaining life cycle according to the second state information and the third state information of the power supply at the end of the vehicle life.

[0099] Exemplarily, the second coefficient is the intermediate value of the second state information and the third state information.

[0100] Specifically, the second state information is represented by SOH2, the third state information is represented by SOH3, and the second coefficient is represented by k2, then k2 = (SOH2 + SOH3) / 2.

[0101] S203. Determine the remaining drivable mileage of the vehicle during the remaining life cycle according to the driving mileage, the first state information, the second state information, the first coefficient, the second coefficient, and the third state information.

[0102] Exemplarily, based on the driving mileage, the vehicle determines the first state information, the second state information, and the third state information. According to the first state information, the second state information, and the third state information, the vehicle determines the first coefficient and the second coefficient, and further determines the remaining drivable mileage of the vehicle when the power supply reaches the third state information from the second state information. Among them, the remaining drivable mileage of the vehicle during the remaining life cycle is represented by the following formula:

[0103]

[0104] Specifically, S1 is the remaining driving mileage of the vehicle within its remaining life cycle, k1 is the first coefficient, k2 is the second coefficient, SOH1 is the first state information, SOH2 is the second state information, SOH3 is the third state information, and S0 is the driving mileage.

[0105] Optionally, S0 is the mileage traveled by the vehicle within the first time period, which is 50,000 km. SOH1 is the health state of the power supply when it just starts on the road, which is 100%. SOH2 is the health state of the power supply after traveling 50,000 km, which is 96.2%. SOH3 is the health state of the power supply at the end of its life, which is 80%. The value of S1 is the remaining driving mileage of the vehicle within its remaining life cycle, which is:

[0106]

[0107] The method for determining the driving mileage of the vehicle provided in this embodiment determines the first coefficient of the power supply within the first time period according to the first state information and the second state information; determines the second coefficient of the power supply within the remaining life cycle according to the second state information and the third state information of the power supply at the end of the vehicle's life; and determines the remaining driving mileage of the vehicle within the remaining life cycle according to the driving mileage, the first state information, the second state information, the first coefficient, the second coefficient, and the third state information.

[0108] Figure 3 It is a flowchart of the method for determining the driving mileage of the vehicle provided in Embodiment III of this application. As Figure 3 shown, the above S103 can be implemented through the following steps

[0109] S301. Obtain the first duration required to charge the power supply from empty to full when it is in the first state information and the second duration required to charge the power supply from empty to full when it is in the second state information.

[0110] Exemplarily, when it is in the first state information, the vehicle obtains the duration required to charge the corresponding power supply from empty to full as the first duration, and when it is in the second state information, the vehicle obtains the duration required to charge the corresponding power supply from empty to full as the second duration.

[0111] Optionally, the charging scenarios for the first duration and the second duration should be the same, and the charging scenarios include but are not limited to: ambient temperature, charging mode, charging current, charging pile brand, charging pile power limit, charging duration, and charging depth.

[0112] S302. Determine the attenuation coefficient of the power supply according to the first state information and the third state information.

[0113] Exemplarily, the attenuation coefficient of the vehicle power supply is the ratio of the third state information to the first state information.

[0114] Specifically, the first state information is represented by SOH1, the third state information is represented by SOH3, and a is the attenuation coefficient, then a = SOH3 / SOH1.

[0115] S303. Determine the third coefficient of the power supply within the first time period according to the first duration and the second duration.

[0116] Exemplarily, the third coefficient of the power supply within the first time period is the average value of the first duration and the second duration.

[0117] Specifically, the first duration is represented by t1, the second duration is represented by t2, and the third coefficient is represented by k3, then:

[0118] k3 = (t1 + t2) / 2

[0119] S304. Determine the fourth coefficient of the power supply within the remaining life cycle according to the first duration, the second duration, and the attenuation coefficient of the power supply.

[0120] Exemplarily, the fourth coefficient of the vehicle power supply within the remaining life cycle is the average value of the sum of the product of the first duration and the attenuation coefficient of the power supply and the second duration.

[0121] Specifically, the first duration is represented by t1, the second duration is represented by t2, the fourth coefficient is represented by k4, and a is the attenuation coefficient, then:

[0122] k4 = (t2 + at1) / 2

[0123] S305. Determine the remaining mileage that the vehicle can travel within the remaining life cycle according to the first duration, the second duration, the third coefficient, the fourth coefficient, the attenuation coefficient, and the driving mileage.

[0124] Exemplarily, based on the first duration, the second duration, the third coefficient, the fourth coefficient, the attenuation coefficient, and the driving mileage obtained by the vehicle according to the above steps, the vehicle further determines the remaining mileage that the vehicle can travel when the power supply reaches the third state information from the second state information. Among them, the remaining mileage that the vehicle can travel within the remaining life cycle is represented by the following formula:

[0125]

[0126] Specifically, S1 is the remaining mileage that the vehicle can travel within the remaining life cycle, t1 is the first duration, t2 is the second duration, k3 is the third coefficient, k4 is the fourth coefficient, S0 is the driving mileage, and a is the attenuation coefficient.

[0127] Optionally, when the power supply is in the first state information, t1 is the duration required for the vehicle to charge the corresponding power supply from empty to full, which is 100 minutes. When the power supply is in the second state information, t2 is the duration required for the vehicle to charge the corresponding power supply from empty to full, which is 96.2 minutes. SOH1 is the health state of the power supply when it just starts on the road, which is 100%. SOH3 is the health state of the power supply at the end of its life, which is 80%. The value of a is the ratio of SOH3 to SOH1, which is 0.8. S0 is the mileage traveled by the vehicle within the first time period, which is 50000 km. The value of S1 is the mileage that the vehicle can travel within the remaining life cycle, which is:

[0128]

[0129] The method for determining the driving mileage of a vehicle provided in this embodiment obtains the first duration required for the power supply to charge from empty to full when in the first state information, the second duration required for the power supply to charge from empty to full when in the second state information, and the third duration required for the power supply to charge from empty to full when in the third state information. According to the first state information and the third state information, the attenuation coefficient of the power supply is determined; furthermore, the third coefficient of the power supply within the first time period and the fourth coefficient of the power supply within the remaining life cycle are determined. According to the first duration, the second duration, the third coefficient, the fourth coefficient, the attenuation coefficient, and the driving mileage, the driving mileage of the vehicle within the remaining life cycle is determined.
