Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a method for determining driving range based on road conditions, a device for determining driving range based on road conditions, a method for displaying and controlling driving range based on road conditions, a device for displaying and controlling driving range based on road conditions, an electronic device, and a new energy vehicle. Background Technology

[0002] Currently, the driving range of gasoline-powered vehicles is calculated as the total distance the car travels continuously after its fuel tank is full. The driving range of electric vehicles is calculated as the total distance traveled from the start of the test with the battery fully charged until the end of the standard-specified test. However, many factors affect a car's driving range. These include heavy traffic in urban areas, different driving habits of each driver, and the fact that drivers who frequently drive aggressively will experience a significantly shorter driving range. Tire pressure, ambient temperature, and the car's weight also all play a role in determining the driving range.

[0003] For example, Chinese patent document CN114683958A, published on July 1, 2022, discloses an electric vehicle and its dual range display control method. Based on real-time data from the vehicle's CAN bus, the method determines the current instantaneous range calculation value, which is used to indicate the vehicle's real-time usage. A first correction result for the current range is determined based on a preset range adjustment amount, the current instantaneous range calculation value, and the previous value displayed on the range meter. A second correction result is determined based on the current theoretical range value and the first correction result, and this second correction result is used as the current displayed value on the range meter. By using real-time data from the vehicle's CAN bus to calculate the instantaneous range, and then correcting the range based on the difference between the instantaneous range and the previous value displayed on the range meter, an accurate range estimation result is obtained. This avoids extensive data statistics, has no application limitations, and significantly improves estimation accuracy. However, this method can only calculate the driving range under the current conditions based on the vehicle's historical fuel consumption data and historical operating conditions. If the vehicle's driving conditions change, there will be a large error.

[0004] A Chinese patent document published on October 15, 2019, with publication number CN110329266A, proposes a method for determining the driving range. The mileage adjustment model in this method is trained based on historical driving data from vehicles of the same model. Since historical driving data for the same vehicle model reflects the driving range in real-world driving conditions, using a mileage adjustment model trained on this data to predict the driving range can achieve more accurate predictions. However, this method can only calculate the driving range using historical data; changes in vehicle driving conditions can lead to significant errors.

[0005] Therefore, it is necessary to provide a method for determining the driving range that takes into account both the current driving conditions of the vehicle and the road conditions to be encountered in the future, so as to better reflect the actual situation of users.

[0045] Currently, most methods for calculating vehicle range based on driving conditions calculate the current or historical driving conditions and the current remaining fuel or battery charge. If the vehicle's driving conditions change, there will be a significant error.

[0046] To address the aforementioned issues, this invention proposes a road condition-based method for determining driving range. This method acquires road condition information for future vehicle travel, calculates fuel consumption based on possible future driving conditions, and combines this with current fuel consumption information to calculate the vehicle's driving range under future conditions. Finally, the driving range is calculated and displayed based on historical driving range and road condition-based driving range. This method not only incorporates historical driving conditions but also considers the vehicle's potential mileage under future road conditions, making it more closely aligned with actual user needs.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Example 1

[0049] The first embodiment of the present invention provides a method for determining driving range based on road conditions, referring to... Figure 1 The method for determining the driving range includes the following steps:

[0050] Step S101: Determine the first driving range Dte1 based on the current remaining energy and the average energy consumption under historical road conditions.

[0051] Step S102: Determine the second driving range Dte2 based on the current remaining energy and the calibrated energy consumption under future road conditions.

[0052] Step S103: Determine the average value of the first driving range Dte1 and the second driving range Dte2, and set the average value as the theoretical value of the driving range Dte = (Dte1 + Dte2) / 2.

[0053] For example, refer to Figure 2 The process of determining the first driving range based on the current remaining energy and the average energy consumption under historical road conditions includes, but is not limited to, the following sub-steps S1011 to S1014.

[0054] Sub-step S1011: Obtain the initial mileage and initial energy consumption.

[0055] For example, an initial energy consumption value (i.e., initial energy consumption) can be determined based on vehicle announcement data. The initial energy consumption can be used to calculate vehicle energy consumption information, such as vehicle fuel consumption / energy consumption information.

[0056] Sub-step S1012: Based on the current mileage and the initial mileage, determine the cumulative mileage; based on the current energy consumption and the initial energy consumption, determine the cumulative energy consumption.

[0057] For example, the vehicle's real-time mileage can be added to the initial mileage to obtain the accumulated mileage, and the vehicle's real-time energy consumption information can be added to the initial energy consumption to obtain the accumulated energy consumption.

[0058] Sub-step S1013: Based on the accumulated energy consumption and accumulated mileage, determine the average energy consumption under historical road conditions.

[0059] For example, the average energy consumption under historical road conditions can be calculated using the following formula: Afe=(Fu / Trip)×100, where Afe is the average energy consumption, L / 100km; Fu is the cumulative energy consumption, L; and Trip is the cumulative mileage, km.

[0060] Furthermore, considering that after a vehicle has continuously driven to a predetermined mileage, the cumulative result of adding the vehicle's real-time mileage and energy consumption information to the initial value is quite large, and the energy consumption change obtained through the above average energy consumption calculation formula is not significant, it is advisable to multiply both the accumulated energy consumption and accumulated mileage by a weighting coefficient before substituting them into the average energy consumption calculation formula. For example, the predetermined mileage can be set to 200km. When the mileage accumulates to 100km, both the numerator (i.e., accumulated energy consumption) and denominator (i.e., accumulated mileage) in the above formula are multiplied by a weighting coefficient of 0.5. The result obtained by multiplying by the weighting coefficient of 0.5 is then used as the initial value for accumulation, which can avoid the insignificant change in energy consumption after driving a large mileage. Of course, the weighting coefficient can also take other values, such as 0.3, 0.6, etc.

[0061] In other words, the vehicle's current mileage can be added to the initial mileage to obtain the accumulated mileage; then it is determined whether the accumulated mileage exceeds the predetermined mileage of 200km. If so, the accumulated mileage and accumulated energy consumption are multiplied by a weighting coefficient of 0.5 and then substituted into the calculation formula to calculate the average energy consumption.

[0062] Sub-step S1014: Determine the quotient between the current remaining energy and the average energy consumption as the first driving range Dte1.

[0063] For example, the current remaining fuel level of a vehicle can be obtained from its fuel pump, and the current remaining battery charge can be obtained from its battery management system (BMS). Then, by dividing the current remaining fuel level (or current remaining battery charge) by the average energy consumption, the initial driving range of a gasoline-powered vehicle (or electric vehicle) under historical road conditions can be calculated.

[0064] For example, refer to Figure 3 The process of determining the second driving range based on the current remaining energy and the calibrated energy consumption under future road conditions includes, but is not limited to, the following sub-steps S1021 to S1023.

[0065] Sub-step S1021: Obtain future road condition information based on vehicle navigation.

[0066] Sub-step S1022: Based on future road condition information, obtain the calibrated energy consumption under different road conditions.

[0067] For example, by acquiring vehicle navigation signals, the road conditions of the vehicle's future route can be obtained. Then, combined with vehicle announcement data, the vehicle's energy consumption under different road conditions can be determined. Finally, based on the future road conditions, the calibrated energy consumption for the vehicle's future journey can be determined. If there is no vehicle navigation information, the vehicle's energy consumption under different road conditions can also be pre-calibrated based on the current road conditions.

[0068] Sub-step S1023: Determine the quotient between the current remaining energy and the rated energy consumption as the second driving range Dte2.

[0069] It should be noted that the energy sources in this embodiment include traditional fuels (such as automobiles and diesel), natural gas, electricity, hydrogen, etc. In other words, the driving range determination method of this invention can be applied not only to the estimation of the driving range of traditional fuel vehicles, but also to the estimation of the driving range of new energy vehicles (e.g., electric vehicles, hybrid vehicles, CNG vehicles, LNG vehicles, hydrogen fuel cell vehicles, etc.).

[0070] The implementation environment of this application embodiment may include at least one terminal and one server, with the method executed on either the terminal or the server. The terminal and server can establish a communication connection to achieve interactive information transmission. The terminal and server calculate the driving range using current remaining energy, historical road conditions, and energy consumption information under future road conditions.

[0071] The terminal can be any electronic product that can interact with the user through one or more methods such as keyboard, touchpad, touch screen, voice interaction, etc., such as PC (Personal Computer), PPC (Pocket Personal Computer), tablet computer, etc.

[0072] A server can be a single server, a server cluster consisting of multiple servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0073] Compared with the method of calculating cruising range only through historical data in the prior art, the cruising range determination method in this embodiment not only considers the current driving condition of the vehicle, but also considers the subsequent road condition of the vehicle, which is closer to the actual situation of the user.

[0074] Second Embodiment

[0075] The second embodiment of the present invention further provides a cruising range display control method, and the cruising range display control method comprises the following steps:

[0076] Step S201: calculating and determining a theoretical display value Dte of the cruising range by using the cruising range determination method in the first embodiment.

[0077] Step S202: correcting and displaying the current displayed value Dis of the cruising range based on the theoretical display value Dte of the cruising range.

[0078] For example, referring to Figure 4 , the process of correcting and displaying the current displayed value of the cruising range based on the theoretical display value of the cruising range includes but is not limited to the following sub-steps S2021 to S2023.

[0079] Sub-step S2021: acquiring the current displayed value Dis of the cruising range in an odometer at the current vehicle speed.

[0080] Sub-step S2022: determining a difference between the theoretical display value Dte of the cruising range and the current displayed value Dis of the cruising range.

[0081] Sub-step S2023: if Dis>Dte, it indicates that the currently displayed cruising range is too large, and the display result of the cruising range is adjusted in a mode that Dis decreases by 1 km when the vehicle travels (1-x) km; if Dis<Dte, it indicates that the currently displayed cruising range is too small, and the display result of the cruising range is adjusted in a mode that Dis decreases by 1 km when the vehicle travels (1+x) km.

[0082] wherein the value of x can be adjusted according to the magnitude of the difference between Dte and Dis. For example, x takes a value of 0 to 0.6.

[0083] Of course, the cruising range displayed in the odometer can also be directly updated to the theoretical value according to the theoretical display value of the cruising range.

[0084] The embodiment provides an implementation mode of approaching the currently displayed cruising range to the calculated cruising range according to the current vehicle speed, which enables the displayed cruising range Dis to be always in dynamic adjustment, and ensures accuracy without jump.
