Description

Technical Field

[0001] The present application relates to the technical field of electric vehicles, and particularly relates to a method, device, equipment and working machine for predicting the cruising range of a vehicle. Background Art

[0002] The cruising range, also known as the endurance capacity, refers to the total mileage that a vehicle such as an automobile or a ship can continuously travel under the current fuel reserve. The cruising range of an electric vehicle refers to the mileage that the electric vehicle can travel with the current power of the power battery on the vehicle. During the driving process of a vehicle, predicting the cruising range for the driver can prompt the driver of the remaining mileage that can be traveled with the current remaining energy, so that the driver can timely charge the vehicle to avoid running out of energy during the driving process.

[0003] Currently, most electric vehicles on the market generally predict the cruising range based on the vehicle's stored battery power and the average energy consumption level of the vehicle, and roughly estimate the driving mileage that the vehicle's stored battery power can still support.

[0054] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0055] Figure 1 is a schematic flowchart of a method for predicting the driving range of a vehicle provided by an embodiment of the present application. As Figure 1 shown, the method for predicting the driving range of a vehicle in this embodiment is applied to an electric vehicle, and the specific steps include:

[0056] S101. Obtain the vehicle driving data, superstructure component working data, remaining battery power, pre-recorded vehicle mass, and pre-recorded lower limit value of battery power of the current vehicle.

[0057] During the driving process of the vehicle, the driver can determine whether the vehicle can reach the destination based on the current driving range of the vehicle, whether it is necessary to store energy for the vehicle during the driving process, etc. Therefore, it is particularly important to predict the driving range of the vehicle.

[0058] Specifically, in order to predict the remaining driving range of the current vehicle, corresponding data that can assist in the prediction needs to be obtained. In this embodiment, the vehicle driving data of the current vehicle, the working data of the superstructure components, the remaining battery power, the pre-recorded vehicle mass, and the pre-recorded lower limit value of the battery power need to be obtained.

[0059] In this embodiment, the vehicle driving data of the current vehicle includes: the driving force of the wheels of the current vehicle, the resistance received by the wheels of the current vehicle, the slope where the current vehicle is located, the acceleration of the current vehicle, and the driving energy consumption of the current vehicle within a preset duration. Among them, since both the driving force of the vehicle's wheels and the resistance received by the wheels are related to the driving speed of the vehicle, therefore, the driving force of the wheels of the current vehicle and the resistance received by the wheels of the current vehicle are obtained by conversion according to the vehicle speed of the current vehicle, and the vehicle speed of the current vehicle can be collected by using a pre-set rotational speed sensor or vehicle speed sensor; the slope where the vehicle is located can be collected by using a pre-set gyroscope; the acceleration of the vehicle can be collected by using a pre-set acceleration sensor; the driving energy consumption of the current vehicle within a preset duration is the energy consumption used for vehicle driving within a preset duration before the current moment recorded during the driving process of the current vehicle.

[0060] In this embodiment, the pre-recorded vehicle mass of the current vehicle refers to the net mass when the vehicle is unloaded. For example, the vehicle mass of a mixer truck is the net mass of the mixer truck before loading materials. Among them, the vehicle mass can be collected and recorded by using an existing vehicle weighing device, and can also be estimated by using an existing vehicle weight estimation device, etc.

[0061] In this embodiment, the working data of the superstructure components of the current vehicle refers to the relevant data when the superstructure components of the current vehicle are working. For example, when the current vehicle is a mixer truck, the corresponding working data of the superstructure components includes: the rotational speed of the mixer truck tank body, the reduction ratio of the reducer, and the mapping relationship between the load capacity and the turning radius pre-constructed. Among them, the rotational speed of the mixer truck tank body can be collected by using a pre-set rotational speed sensor; the reduction ratio of the reducer is a pre-recorded parameter related to the reducer; the turning radius of the mixer truck tank body is related to the load capacity of the mixer truck, and the turning radius corresponding to the current load capacity of the mixer truck can be queried from the pre-constructed mapping relationship between the load capacity and the turning radius.

[0062] In this embodiment, the remaining battery power of the current vehicle can be represented by the current SOC value of the battery (i.e., the state of charge). In this embodiment, the current SOC value of the battery can be obtained by using an existing battery SOC collection method. Since completely exhausting the battery power will seriously affect the battery life, therefore, in order to improve the battery life, a lower limit value of the battery power is pre-set. The power of the battery that is more than the lower limit value of the battery power is used as the available power of the battery. Usually, 10% - 20% of the total battery capacity is set as the lower limit value of the battery power. In this embodiment, it is preferably set that 15% of the total battery capacity is used as the lower limit value of the battery power.

[0063] S102. Determine the basic mileage energy consumption of the current vehicle and the on-board energy consumption of the current vehicle based on the vehicle's gross weight, vehicle driving data, and on-board component working data. The on-board energy consumption of the current vehicle is the additional loss other than the vehicle's cruising range.

[0064] Specifically, after obtaining the relevant data for assisting in predicting the cruising range through the above steps, it is necessary to calculate all the energy consumptions corresponding to each unit time of driving based on these data, specifically including: basic mileage energy consumption (i.e., the driving energy consumption per unit time of driving) and the additional energy consumption other than the cruising range. Among them, for a vehicle with on-board components, during driving, it not only has driving energy consumption but also on-board energy consumption. Therefore, the on-board energy consumption is the additional energy consumption other than the cruising range. Therefore, in this embodiment, it is necessary to calculate the basic mileage energy consumption and the on-board energy consumption. Among them, the basic mileage energy consumption is the driving energy consumption of the current vehicle per unit time of driving, and the on-board energy consumption is the on-board energy consumption generated by the work of the on-board components per unit time of driving of the current vehicle.

[0065] Further, this step specifically includes:

[0066] First, determine the cargo load of the current vehicle based on the wheel driving force, the resistance received by the wheels, the slope where the vehicle is located, the acceleration, and the vehicle's gross weight.

[0067] If the cargo load of the vehicle is different, then the on-board energy consumption and the basic mileage energy consumption are also different. Therefore, in this embodiment, it is necessary to first determine the cargo load of the current vehicle, and then calculate the on-board energy consumption of the current vehicle and the basic mileage energy consumption of the current vehicle. This embodiment uses the pre-obtained wheel driving force of the current vehicle, the resistance received by the wheels of the current vehicle, the slope where the current vehicle is located, the acceleration of the current vehicle, and the vehicle's gross weight of the current vehicle to calculate the cargo load of the current vehicle. Among them, relevant parameters are also needed for auxiliary calculation during the calculation process, such as the inertia coefficient, rolling resistance coefficient, etc. The calculation formula for the cargo load of the current vehicle is as follows:

[0068]

[0069] Where M 1 represents the cargo load, M 0 represents the vehicle's gross weight, F t represents the wheel driving force, F w represents the resistance received by the wheels, g represents the acceleration due to gravity, F r represents the rolling resistance coefficient, α represents the slope where the vehicle is located, λ represents the inertia coefficient, and a represents the acceleration.

[0070] For a mixer truck, since the loading of the mixer truck is often an integer, when the calculated load capacity is within the range of (Nm ± 3%), the load capacity can be directly taken as Nm, where N is a natural number integer and m is the load mass per cubic meter. According to the difference between dry and wet materials loaded by the mixer truck, the value of the load capacity is different. When the calculated load capacity is 1m, if dry materials are loaded, the actual load capacity of the current vehicle is less than 1m. At this time, the load capacity of the current vehicle is subtracted by a preset percentage. If wet materials are loaded, the actual load capacity of the current vehicle is greater than 1m. At this time, the load capacity of the current vehicle is added by a preset percentage.

[0071] Second, determine the upper mounting energy consumption of the current vehicle according to the load capacity and the working data of the upper mounting assembly.

[0072] In this embodiment, according to the pre - constructed mapping relationship between the load capacity and the turning radius included in the working data of the upper mounting assembly, the turning radius corresponding to the load capacity of the current vehicle is queried as the turning radius of the current vehicle. Then, according to this turning radius, the mixer truck tank rotation speed and the reduction gear ratio included in the working data of the upper mounting assembly, the upper mounting power of the current vehicle is calculated, and this upper mounting power is the upper mounting energy consumption of the current vehicle. The calculation formula for the upper mounting power of the current vehicle is as follows:

[0073]

[0074] Among them, P 0 represents the upper mounting power, n represents the mixer truck tank rotation speed, i represents the reduction gear ratio, and r represents the turning radius corresponding to the load capacity M 1 corresponding to.

[0075] Third, determine the basic mileage energy consumption of the current vehicle according to the cycle condition power consumption corresponding to the load capacity, the driving energy consumption within a preset duration, and the preset duration.

[0076] In this embodiment, the cycle condition power consumption of the vehicle is the cycle condition unit mileage power consumption of the legally specified condition or the 40km / h constant speed unit mileage power consumption. In this embodiment, the cycle condition power consumptions corresponding to several different load capacities are pre - recorded. This embodiment can obtain the cycle condition power consumption corresponding to the load capacity of the current vehicle by performing interpolation processing on the load capacity of the current vehicle. This embodiment can calculate the basic mileage energy consumption of the current vehicle by using the cycle condition power consumption corresponding to the load capacity of the current vehicle, the driving energy consumption within a preset duration, and this preset duration.

[0077] Furthermore, this step specifically includes:

[0078] First, determine whether the driving target and driving route of the current vehicle are obtained.

[0079] If the driver of the current vehicle has pre-entered a driving target and determined a driving route to reach the driving target, the basic mileage energy consumption of the current vehicle can be determined based on the relevant data of historical driving. However, if the driving target and driving route of the current vehicle are uncertain, the relevant data of historical driving cannot be used to determine the basic mileage energy consumption of the current vehicle. Therefore, before determining the basic mileage energy consumption of the current vehicle, it is first necessary to determine whether the driving target and driving route of the current vehicle have been obtained. Among them, the driving route can be the driving route output by the map software connected to the current vehicle from the current location to the driving target.

[0080] Second, if the driving target and driving route of the current vehicle are obtained, the basic mileage energy consumption of the current vehicle is determined according to the historical energy consumption data matching the load capacity, driving target and driving route of the current vehicle.

[0081] If the driving target and driving route of the current vehicle are obtained, the energy consumption data in the historical driving data of the current vehicle recorded in the past big data can be extracted as the historical energy consumption data from the historical driving data matching the load capacity, driving target and driving route of the current vehicle. Then, big data statistical analysis is performed on the extracted historical energy consumption data to determine the basic mileage energy consumption of the current vehicle. Since the basic mileage energy consumption is statistically analyzed based on the historical energy consumption data matching the current driving route, taking into account the road congestion and uphill and downhill conditions in the driving route, the analyzed basic mileage energy consumption is more accurate.

[0082] Third, if the driving target and driving route of the current vehicle are not obtained, the basic mileage energy consumption of the current vehicle is determined according to the cycle condition power consumption corresponding to the load capacity, the driving energy consumption within a preset duration, and the preset duration.

[0083] If the driving target and driving route of the current vehicle are not obtained, then directly use the cycle condition power consumption corresponding to the load capacity of the current vehicle, the driving energy consumption within a preset duration, and the preset duration to calculate the basic mileage energy consumption of the current vehicle. In this embodiment, combining the cycle condition power consumption of the regulatory specified conditions and the driving energy consumption in the actual driving process, compared with only using the actual driving energy consumption or only using the cycle condition power consumption of the regulatory specified conditions to determine the basic mileage energy consumption of the current vehicle, the accuracy is higher. The specific calculation formula is as follows:

[0084]

[0085] Among them, P 1 represents the basic mileage energy consumption of the current vehicle, P 2 represents the cycle condition power consumption corresponding to the load capacity of the current vehicle, n represents the preset duration, such as n hours, ∑P nIndicates the driving energy consumption within a preset duration, such as the driving energy consumption in the previous n hours from the current moment.

[0086] S103. Determine the cruising range of the current vehicle according to the remaining battery power, the lower limit value of the battery power, the basic mileage energy consumption, and the additional loss.

[0087] Specifically, in this embodiment, the value obtained by subtracting the pre-recorded lower limit value of the battery power from the remaining battery power of the current vehicle is used as the available battery power of the current vehicle, and the sum of the basic mileage energy consumption of the current vehicle and the additional loss of the current vehicle is used as the total energy consumption of the current vehicle. The cruising range of the current vehicle is calculated using the available battery power of the current vehicle and the total energy consumption of the current vehicle. For example, if the total energy consumption of the current vehicle is the total energy consumption per unit mileage, then the available battery power of the current vehicle is divided by the total energy consumption per unit mileage to calculate the mileage that the available battery power of the current vehicle can still travel, that is, the cruising range. If the total energy consumption of the current vehicle is the total energy consumption per unit time, then the available battery power of the current vehicle is divided by the total energy consumption per unit time to calculate the duration that the available battery power of the current vehicle can still travel, and then according to the average speed of the current vehicle, the cruising range of the current vehicle can be predicted.

[0088] As can be seen from the above introduction, for the vehicle cruising range prediction method of the embodiments of the present application, vehicle driving data, upper mounting component working data, remaining battery power, pre-recorded vehicle mass, and pre-recorded lower limit value of the battery power of the current vehicle are obtained; according to the vehicle mass, vehicle driving data, and upper mounting component working data, the basic mileage energy consumption of the current vehicle and the upper mounting energy consumption of the current vehicle are determined, and the upper mounting energy consumption of the current vehicle is the additional loss other than the cruising range of the current vehicle; according to the remaining battery power, the lower limit value of the battery power, the basic mileage energy consumption, and the additional loss, the cruising range of the current vehicle is determined. By adopting the technical solution of this embodiment, the cruising range of the vehicle can be predicted in combination with the upper mounting energy consumption during the upper mounting work, avoiding the influence of the upper mounting work on the cruising range prediction, and improving the accuracy of the cruising range prediction of the vehicle.

[0089] Further, Figure 2 is a flowchart of another vehicle cruising range prediction method provided by the embodiments of the present application. As Figure 2 shown, before performing step S103, the vehicle cruising range prediction method of this embodiment further includes the following steps:

[0090] S203. Obtain the temperature data of the current vehicle and the driving duration of the current vehicle.

[0091] Specifically, in addition to the energy consumption of the superstructure, the additional losses of the current vehicle other than the cruising range also include the air-conditioning energy consumption. To determine the air-conditioning energy consumption, it is necessary to obtain the temperature data of the current vehicle and the driving duration of the current vehicle. Among them, the temperature data of the current vehicle includes: the in-vehicle temperature, the out-vehicle temperature, and the set temperature set by the driver. The in-vehicle temperature is collected by a temperature sensor installed inside the vehicle, the out-vehicle temperature is collected by a temperature sensor installed outside the vehicle, and the set temperature is the temperature input by the driver collected through a temperature input device. For those with a known driving destination, the driving duration of the current vehicle to reach the destination can be determined according to the driving mileage between the current location and the destination. Among them, the driving duration can be calculated according to the driving mileage between the current location and the destination and the average vehicle speed of the current vehicle, or the driving duration estimated by the map software set on the current vehicle can be directly obtained. For the case where the driving destination is unknown, a default value of the driving duration can be preset and used as the driving duration of the current vehicle.

[0092] S204. Query the air-conditioning energy consumption corresponding to the temperature data of the current vehicle from the pre-constructed mapping relationship between temperature and air-conditioning energy consumption.

[0093] Specifically, in this embodiment, a multi-dimensional simulation model is pre-constructed according to the relevant parameters of the current vehicle (such as in-vehicle temperature, out-vehicle temperature, set temperature, cockpit size, air-conditioning fan efficiency, plate heat exchanger area, pipeline loss, etc.). Among them, the parameters such as the cockpit size of the current vehicle, the air-conditioning fan efficiency of the current vehicle, the air-conditioning plate heat exchanger area of the current vehicle, and the air-conditioning pipeline loss of the current vehicle are fixed parameters. Therefore, the air-conditioning energy consumption table corresponding to the fixed parameters of the current vehicle can be calculated using this simulation model. Among them, the air-conditioning energy consumption table is the air-conditioning energy consumption corresponding to different in-vehicle temperatures, different out-vehicle temperatures, and different set temperatures under the fixed parameters of the current vehicle. This air-conditioning energy consumption table is the mapping relationship between temperature and air-conditioning energy consumption. In this embodiment, the air-conditioning energy consumption corresponding to the in-vehicle temperature, out-vehicle temperature, and set temperature of the current vehicle can be queried from the mapping relationship between temperature and air-conditioning energy consumption.

[0094] S205. Take the ratio between the air-conditioning energy consumption of the current vehicle and the driving duration of the current vehicle as the basic air-conditioning energy consumption of the current vehicle. The basic air-conditioning energy consumption of the current vehicle and the energy consumption of the superstructure of the current vehicle are both additional losses of the current vehicle other than the cruising range.

[0095] In this embodiment, the basic mileage energy consumption of the current vehicle and the additional energy consumption of the current vehicle other than the endurance are both the basic energy consumption of the current vehicle. Since the basic energy consumption corresponding to the air-conditioning energy consumption of the current vehicle also needs to be determined, the value obtained by dividing the air-conditioning energy consumption of the current vehicle by the driving duration of the current vehicle is used as the basic air-conditioning energy consumption of the current vehicle. Then, the upfit energy consumption of the current vehicle and the basic air-conditioning energy consumption of the current vehicle are both used as the additional energy consumption of the current vehicle other than the endurance.

[0096] In this embodiment, the execution order between step S201 to step S202 and step S203 to step S204 is not limited in this embodiment. That is, step S201 to step S202 can be executed first, and then step S203 to step S204 can be executed; or step S203 to step S204 can be executed first, and then step S201 to step S202 can be executed; or step S201 to step S202 and step S203 to step S204 can be executed simultaneously.

[0097] Figure 2 The steps S201 to S202 shown are Figure 1 the same as the steps S101 to S102 shown, Figure 2 the step S206 shown is Figure 1 the same as the step S103 shown. The execution contents of steps S201, S202, and S206 are not specifically elaborated in this embodiment.

[0098] Furthermore, Figure 3 is a flowchart of another vehicle endurance prediction method provided by an embodiment of the present application. As Figure 3 shown, for the vehicle endurance prediction method of this embodiment, before executing step S103, the following steps are further included:

[0099] S303. According to the pre-constructed mapping relationship between temperature and battery correction coefficient and the pre-obtained outside temperature of the current vehicle, query the battery correction coefficient corresponding to the outside temperature.

[0100] Specifically, the ambient temperature of the vehicle battery is the outside temperature of the vehicle, and the battery is affected by the temperature, which in turn affects the battery's power storage capacity. For example, the battery's power storage capacity is higher when the weather is warmer than when it is colder. Therefore, in order to improve the accuracy of predicting the cruising range, this embodiment needs to consider the influence of the outside temperature on the battery and pre - construct a mapping relationship between the temperature and the battery correction coefficient. The battery correction coefficient corresponding to a certain temperature is the ratio of the actual battery power to the calculated battery power under the environment of that temperature. For example, when the outside temperature is - 5°C, the corresponding battery correction coefficient is 0.95; when the outside temperature is - 10°C, the corresponding battery correction coefficient is 0.9; when the outside temperature is - 15°C, the corresponding battery correction coefficient is 0.88, etc. This embodiment needs to query the battery correction coefficient corresponding to the current outside temperature of the vehicle from the pre - constructed mapping relationship between the temperature and the battery correction coefficient.

[0101] S304. Determine the cruising range of the current vehicle according to the remaining battery power, the lower limit of the battery power, the basic mileage energy consumption, the additional loss, and the battery correction coefficient.

[0102] Specifically, in order to improve the accuracy of predicting the cruising range, when predicting the cruising range, it is necessary to consider the battery correction coefficient corresponding to the current outside temperature. That is, according to the remaining battery power, the lower limit of the battery power, the basic mileage energy consumption, the additional loss, and the battery correction coefficient, determine the cruising range of the current vehicle. The specific steps are as follows:

[0103] First, take the difference between the remaining battery power of the current vehicle and the pre - recorded lower limit of the battery power, multiply the obtained value by the battery correction coefficient of the current vehicle as the available battery power of the current vehicle, and take the sum of the basic mileage energy consumption of the current vehicle and the additional loss of the current vehicle as the total energy consumption of the current vehicle;

[0104] Second, take the ratio of the available battery power of the current vehicle to the total energy consumption of the current vehicle as the cruising range of the current vehicle.

[0105] Steps S303 and S304 of this solution can also be executed Figure 2 after step S204 in

[0106] When the additional loss includes the upper - loading energy consumption and the basic air - conditioning energy consumption, the calculation formula for the cruising range of the current vehicle is as follows:

[0107]

[0108] Among them, D represents the cruising range, SOC 1 represents the remaining battery power, SOC 0 represents the lower limit of the battery power, P oIndicates the upper body energy consumption in the additional loss, P 1 Indicates the energy consumption for the basic mileage, P 2 Indicates the basic air-conditioning energy consumption in the additional loss, and η represents the battery correction coefficient.

[0109] Figure 3 The steps S301 - S302 shown in Figure 1 are the same as the steps S101 - S102 shown in

[0110] Furthermore, Figure 4 is a schematic diagram of the processing flow for determining the available duration of the upper body of the current vehicle provided by the embodiment of the present application. As Figure 4 shown, the vehicle endurance mileage prediction method of this embodiment further includes the following steps:

[0111] S401: Multiply the difference between the remaining battery power and the lower limit of the battery power by the battery correction coefficient, and use the obtained value as the available battery power of the current vehicle.

[0112] S402: Use the ratio of the available battery power of the current vehicle to the upper body energy consumption of the current vehicle as the available duration of the upper body of the current vehicle.

[0113] In this embodiment, the available duration of the upper body of the current vehicle is the working duration when only using the available battery power of the current vehicle for upper body work. The available battery power of the current vehicle is calculated using the battery correction coefficient of the current vehicle. Therefore, the influence of the external temperature on the battery's power storage capacity is considered, improving the accuracy of predicting the available duration of the upper body. Among them, the calculation formula for the available duration T of the upper body of the current vehicle is:

[0114]

[0115] Furthermore, the vehicle endurance mileage prediction method of this embodiment further includes the following steps:

[0116] First, obtain the distance between the charging and swapping station within the endurance mileage of the current vehicle and the current vehicle.

[0117] Specifically, after predicting the endurance mileage of the current vehicle, the charging and swapping stations within this endurance mileage searched by a pre-set map software can also be obtained, so as to obtain the distance between the charging and swapping station and the current vehicle. The charging and swapping stations within the endurance mileage refer to the distance from the current position of the current vehicle to the charging and swapping station being less than the predicted endurance mileage of the current vehicle, thereby ensuring that the current vehicle can search for a charging and swapping station that the current vehicle can drive to in time for vehicle energy storage when the endurance mileage is relatively small.

[0118] Second, output the remaining mileage of the current vehicle and the distance to the charging and swapping station.

[0119] In this embodiment, the remaining mileage of the current vehicle and the distance to the charging and swapping station can be output for the driver to view. The driving route to the charging and swapping station can also be output to facilitate the driver to drive to the charging and swapping station according to the driving route to charge the current vehicle. If there are multiple charging and swapping stations within the remaining mileage of the current vehicle, this embodiment can also output the driving routes and the distances to the charging and swapping stations of multiple charging and swapping stations for the driver to select the target charging and swapping station by himself.

[0120] In addition, this embodiment can also output the available duration of the upper body when the current vehicle only performs the upper body work, so as to avoid sudden stops during the upper body work. Among them, the remaining mileage of the current vehicle, the distance to the charging and swapping station of the current vehicle, and the available time of the upper body of the current vehicle can all be output to the human-machine interaction device to display these data to the driver.

[0121] Corresponding to the above vehicle remaining mileage prediction method, an embodiment of the present application also proposes a vehicle remaining mileage prediction device.
