[0001] This application claims priority to Chinese Patent Application No. 202411164441.5, filed on August 23, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of pure electric vehicle range technology, specifically to a method and system for improving the range of a pure electric vehicle during driving. BACKGROUND

[0003] The remaining range of an electric vehicle refers to the distance the vehicle can continue to travel with the current battery level. This distance is calculated based on various factors, including but not limited to the remaining battery level, the vehicle's driving speed, road conditions (such as slope, road conditions, etc.), vehicle load, environmental temperature, and battery aging status, etc.

[0004] During actual driving, road conditions (such as slope, road conditions, etc.), vehicle load, environmental temperature, etc. are unchangeable. With the battery level determined, optimizing the overall vehicle energy consumption is the only way to improve the range. There is a lack of methods in the prior art that can clearly guide the optimization of overall vehicle energy consumption. SUMMARY

[0005] The problem to be solved by the present application is to provide a method and system for improving the range of a pure electric vehicle during driving, which can analyze the current time operations that can be optimized, calculate the corresponding improvement value of the remaining range of the vehicle after each optimized operation is implemented, provide clear guidance for optimizing energy consumption, and scientifically and rigorously improve the remaining range of the vehicle during driving.

[0083] The specific embodiments of the present application will be further described in combination with the drawings. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application.

[0084] Embodiment 1

[0085] Fig. 1 shows a method for improving the endurance of a pure electric vehicle during driving according to the present application, which is suitable for a pure electric vehicle in driving. One driving process refers to a process in which the vehicle increases from zero speed to zero speed. As shown in Fig. 1, the method for improving the endurance of a pure electric vehicle during driving includes the following steps S10-S40.

[0086] Step S10: obtaining the remaining power, the estimated power consumption and the estimated vehicle speed at the current time of the vehicle, and the working state of the closable function system affecting the power consumption.

[0087] (1) In some embodiments, the method for obtaining the estimated power consumption at the current time of the vehicle includes: determining whether the current time is before the power consumption statistical starting time, if yes, then the basic power consumption is the estimated power consumption; if not, then obtaining the estimated power consumption according to the vehicle driving condition from the power consumption statistical starting time to the current time. Wherein, the process in which the vehicle speed increases from zero to zero is called a driving process, and the power consumption statistical starting time refers to the time when the vehicle exceeds the set speed for the first time in the driving process.

[0088] Each time the vehicle is powered on and driven, the initial driving process has a short statistical data, and a change in a certain factor, such as a change in vehicle speed, will cause a large fluctuation in average energy consumption. In order to avoid this problem, the power consumption statistical starting time is defined as the time when the vehicle speed exceeds the set speed for the first time in a driving process, so that the influence of the initial driving on the vehicle energy consumption calculation can be avoided. The set speed is usually 8-12 km / h, and the optimal value is 10 km / h.

[0089] After determining the starting point of the electricity consumption statistics, in a driving process, the basic electricity consumption is set as the estimated electricity consumption before the starting point of the electricity consumption statistics, where the basic electricity consumption can be the displayed electricity consumption of the vehicle (calculated according to the historical driving mileage and electricity consumption of the vehicle) or the given electricity consumption (calculated according to the basic electricity consumption of the vehicle itself under normal road conditions, such as the vehicle boundary and working condition required by the national standard GB / T 18386.1-2021 Electric Vehicle Energy Consumption and Range Test Method); after the starting point of the electricity consumption statistics, the estimated electricity consumption is calculated according to the specific actual driving conditions, and the specific method can include the following steps a1 and a2.

[0090] In addition, the speed of the vehicle during driving is displayed in real time, so the time when the speed first exceeds the set speed during a driving process can be easily recorded.

[0091] Step a1: Obtain the driving mileage and consumed electricity from the starting point of the electricity consumption statistics to the current time.

[0092] SOC (State of Charge) refers to the state of charge of the battery, which is an indicator of the remaining percentage of battery capacity. SOC interpolation usually refers to the process of estimating or correcting SOC under different conditions (such as different temperatures, different discharge rates, etc.). Generally, a pure electric vehicle can accurately reflect the remaining battery capacity under different conditions through the SOC interpolation algorithm, thereby improving the accuracy and reliability of the battery management system.

[0093] In addition, most electric vehicles have a dashboard that displays the current battery remaining capacity, real-time electricity consumption, remaining range, and driven mileage, etc. For driving: time, remaining capacity change data, electricity consumption change data, driving mileage change data, etc. can be recorded through vehicle system function expansion, or some corresponding equipment can be installed for storage and recording, to achieve direct calling during use. Considering the cost of data storage and processing, a rolling storage method can be used to store only the historical data records of the last few driving processes.

[0094] Therefore, a pure electric vehicle can easily obtain the driving mileage and remaining capacity at the starting point of the electricity consumption statistics, as well as the driving mileage and remaining capacity at the current time, and the driving mileage and consumed electricity between the two times can be obtained by subtracting the values of the two times.

[0095] Step a2: judging whether the driving distance from the starting point of the electricity consumption statistics to the current time is greater than the first set driving distance, if yes, calculating the average electricity consumption in the first set driving distance before the current time as the estimated electricity consumption; if not, assuming that the vehicle continues to drive to the first set driving distance at the basic electricity consumption on the basis of the driving distance from the starting point of the electricity consumption statistics to the current time, and calculating the average electricity consumption in the first set driving distance as the estimated electricity consumption. Usually, the first set driving distance is 15-25km, and the optimal value is 20km.

[0096] The average electricity consumption is calculated from the starting point of the electricity consumption statistics to the first set driving distance. If the first set driving distance is not met, the basic electricity consumption is filled in. The average electricity consumption calculated in this way as the estimated electricity consumption can better represent the actual situation.

[0097] Optionally, calculating the average electricity consumption in the first set driving distance before the current time comprises: obtaining the consumed electricity in the first set driving distance before the current time; and dividing the consumed electricity in the first set driving distance before the current time by the first set driving distance, so as to obtain the average electricity consumption in the first set driving distance before the current time.

[0098] As described above, the pure electric vehicle can record the change data of the remaining electricity and the change data of the driving distance during driving, and therefore the consumed electricity in the first set driving distance before the current time can be obtained through these historical data. For example, the driving distance and the remaining electricity at the current time are obtained first, and then the driving distance at the current time is subtracted by the first set driving distance to obtain a distance; then the time and the remaining electricity corresponding to the distance are obtained by consulting the historical data; and then the remaining electricity corresponding to the distance is subtracted by the remaining electricity at the current time, so as to obtain the consumed electricity in the first set driving distance before the current time.

[0099] Optionally, calculating the average electricity consumption in the first set driving distance as the estimated electricity consumption comprises: obtaining the consumed electricity of the assumed part of driving to the first set driving distance at the basic electricity consumption; summing the consumed electricity from the starting point of the electricity consumption statistics to the current time and the consumed electricity of the assumed part of driving to the first set driving distance at the basic electricity consumption; and then dividing the obtained consumed electricity by the first set driving distance, so as to obtain the average electricity consumption in the first set driving distance.

[0100] In summary, the specific calculation formula of the estimated electricity consumption according to the specific actual driving condition is as follows:

[0101]

[0102] In the formula, is the estimated electricity consumption of the vehicle at the current time; is the basic electricity consumption; the consumed electric quantity from the starting time of the electric consumption statistics to the current time; the starting time of the electric consumption statistics; the current time; the driving distance from the starting time of the electric consumption statistics to the current time; the first set driving distance.

[0103] In addition, the unit of the electric consumption in the context is kWh / 100km (kilowatt hour per 100 kilometers), the unit of the electric quantity is kWh (kilowatt hour), the unit of the distance is kilometers km, the unit of the time is hours h, and the unit of the speed is kilometers per hour km / h.

[0104] (2) In some embodiments, the method for obtaining the estimated speed of the vehicle at the current time includes the following steps b1 and b2.

[0105] Step b1: obtaining the total driving distance and the total driving time of the vehicle from the starting time of driving to the current time.

[0106] The starting time of driving is the starting time of the current driving process or the time when the speed is zero. As described above, the electric vehicle can easily obtain the driving distance and time at the starting time of driving, and the driving distance and time at the current time. The driving distance and driving time between the two times are obtained by subtracting the values of the two times, i.e., the total driving distance and the total driving time.

[0107] Step b2: determining whether the total driving distance of the vehicle from the starting time of driving to the current time is greater than the second set driving distance. If yes, the average speed within the second set driving distance before the current time is calculated as the estimated speed. If not, the average speed of the vehicle from the starting time of driving to the current time is calculated as the estimated speed. Usually, the second set driving distance is 15-25 km, and the optimal value is 20 km.

[0108] The average speed is calculated from the starting time of driving to the average electric consumption within the second set driving distance. If the second set driving distance is not met, the entire driving process is calculated. The average speed calculated in this way as the estimated speed can better represent the actual situation.

[0109] Optionally, calculating the average speed within the second set driving distance before the current time includes: obtaining the driving time within the second set driving distance before the current time; and dividing the second set driving distance by the driving time within the second set driving distance before the current time, to obtain the average speed within the second set driving distance before the current time.

[0110] As above, the pure electric vehicle can record the time and the change data of the driving mileage during the driving process, and thus the driving time within the second set driving mileage before the current time can be obtained through the historical data. For example, the driving mileage and the time at the current time are obtained first, the second set driving mileage is subtracted from the driving mileage at the current time to obtain a mileage number; then the historical data are consulted to obtain the time corresponding to the mileage number; and then the time corresponding to the mileage number is subtracted from the current time, so that the driving time within the second set driving mileage before the current time is obtained.

[0111] Optionally, the average speed of the vehicle from the driving start time to the current time comprises: dividing the total driving mileage of the vehicle from the driving start time to the current time by the total driving time, so as to obtain the average speed of the vehicle from the driving start time to the current time.

[0112] In summary, the obtaining formula of the estimated speed is as follows:

[0113] ,

[0114] In the formula, is the estimated speed of the vehicle at the current time; is the total driving time of the vehicle from the driving start time to the current time; is the driving time within the second set driving mileage before the current time; is the total driving mileage of the vehicle from the driving start time to the current time; is the second set driving mileage.

[0115] (3) In some embodiments, the method for obtaining the working state of the closable function system affecting the power consumption comprises: obtaining whether the closable function system affecting the power consumption is working.

[0116] Specifically, whether the air conditioning system, the audio and video system, the intelligent driving function system and the like are in the open working state can be easily obtained through the vehicle-mounted system.

[0117] Step S20: According to the estimated speed of the vehicle at the current time and the working state of the closable function system affecting the power consumption, the operation that can be optimized at the current time of the vehicle is determined, and the optimized power consumption of each operation that can be optimized is obtained, wherein each operation that can be optimized can improve the remaining cruising range of the vehicle after implementation.

[0118] During the driving process of the vehicle, in order to improve the remaining cruising range of the vehicle, the power consumption of the vehicle needs to be reduced, and the specific method is to reduce the speed and close some unnecessary function systems.

[0119] (1) In some embodiments, determining the operation that can be optimized at the current time of the vehicle according to the estimated vehicle speed at the current time of the vehicle and the working state of the closable function system that affects the electricity consumption can specifically include the following steps c1 and c2.

[0120] Step c1: judging whether the estimated vehicle speed at the current time of the vehicle is greater than the optimal economic speed, if yes, the operation that can be optimized at the current time of the vehicle includes limiting the vehicle speed to be less than the optimal economic speed.

[0121] Generally speaking, the most fuel-efficient speed of a fuel vehicle is 80-100km, and the most fuel-consuming speed is in the congested urban road section, and the most fuel-efficient speed is in the cruise on the highway; the most economic speed of an electric vehicle is generally 50-60km, and the lower the speed, the more power saving, and the speed above 90km / h on the highway is the most power-consuming. The economic speed of an electric vehicle refers to the speed range at which the electric vehicle can achieve the maximum driving range with the least energy consumption during driving. This speed range varies due to factors such as the model, power system and battery performance of the electric vehicle. The optimal economic speed in the present application is set according to the specific vehicle, and is generally 40-60km / h.

[0122] The estimated vehicle speed at the current time of the vehicle is greater than the optimal economic speed, which means that the speed can be limited below the optimal economic speed to reduce electricity consumption and improve the remaining range.

[0123] Step c2: judging whether each closable function system that affects the electricity consumption is working at the current time of the vehicle, if a certain closable function system is working, the operation that can be optimized at the current time of the vehicle includes closing the closable function system, wherein the closable function system that affects the electricity consumption includes the air conditioning system, the audio-video system and the intelligent driving function system.

[0124] By closing some function systems of the vehicle, the power consumption is reduced and the remaining range is improved. The high-voltage accessories that mainly affect the electricity consumption of the electric vehicle during driving are the air conditioning system, the low-voltage accessories are the audio-video system and the intelligent driving function system, etc.

[0125] The intelligent driving function system, i.e. the intelligent driving assistance system, is an automotive electronic control system that identifies and analyzes the dynamic conditions of the vehicle and the behavior of the driver through the integration of advanced sensors, controllers and actuators, and provides corresponding driving assistance or automatic driving functions. This system aims to improve the comfort, safety and efficiency of driving and reduce traffic accidents.

[0126] With the continuous progress of technology and the improvement of regulations, intelligent driving assistance systems will show a diversified and deepening development trend in the future. Autonomous driving technology will gradually develop from the current L2 level to L3, L4, and even L5 level. Vehicles will be able to achieve autonomous driving in a wider range of roads and environmental conditions. At the same time, the fusion application of sensor technology, the optimization of AI algorithms, the development of car-road collaboration technology, and the improvement of laws and regulations will all promote intelligent driving assistance systems to further improve driving safety and practicality. Currently, intelligent driving function systems are usually divided into two categories: driving functions and parking functions, covering multiple levels from simple driving assistance to complex autonomous driving.

[0127] ①Driving functions include the following functional systems: Adaptive Cruise Control (ACC): automatically controls the acceleration and deceleration of the vehicle, maintaining a safe distance from the vehicle in front. This function is particularly useful when driving at high speeds, reducing driver fatigue. Lane Centering Control (LCC): keeps the vehicle driving in the center of the lane, reducing the driver's lateral control burden, which helps to improve driving stability and safety. Auto Lane Change (ALC): automatically completes the lane change operation of the vehicle under the driver's instructions. This function perceives the surrounding vehicles and road conditions to ensure the safety of the lane change process. Traffic Jam Assistant (TJA): in traffic congestion, combines ACC and LCC functions to achieve low-speed following and lane keeping. This helps to alleviate the stress of the driver in congested road conditions. Navigate On Autopilot (NOA): on highways or urban roads, according to navigation information, realizes automatic driving from one point to another. This function requires high-precision maps and navigation information support.

[0128] ②Parking functions include the following functional systems: Auto Parking Assist System (APA): automatically identifies parking spaces and completes parking operations. This function automatically plans a parking path and performs parking actions by sensing parking spaces and surrounding obstacles. Remote Parking Assist (RPA): allows the driver to complete parking from outside the vehicle through a remote control device. This function is particularly useful in narrow parking spaces or when the driver has difficulty getting out of the vehicle. Smart Summon (SS): through remote control methods such as mobile phone APP, let the vehicle automatically drive to the designated position, which helps to improve the convenience and practicality of the vehicle. Home Park Assist (HPA): remembers a specific parking space in a specific parking lot and automatically completes the parking process. This function requires the vehicle to learn and remember the layout and parking space location of the parking lot in advance. Autonomous Valet Parking (AVP): automatically finds a parking space and completes parking in an unknown parking lot. The driver can leave the vehicle. This is one of the more advanced functions in current intelligent driving technology.
