Description

Technical Field

[0002] The driving range, also known as the endurance capacity, refers to the total mileage that vehicles such as automobiles and ships can continuously travel with the maximum fuel reserve.

[0057] 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 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 belong to the scope of protection of the present application.

[0058] The embodiments of the present application provide a method for predicting the remaining driving range. Refer to Figure 1 , Figure 1 It is a flowchart of the method for predicting the remaining driving range provided by the embodiments of the present application. As Figure 1 shown, it includes the following steps:

[0059] Step 101: Predict the first driving path of the vehicle according to the target positioning signal of the vehicle;

[0060] In this step, the target positioning signal of the vehicle is obtained through the Beidou positioning system or the GPS positioning system. According to the target positioning signal of the vehicle, the approximate initial motion trajectory of the vehicle can be determined, and then the first driving path of the vehicle can be predicted according to the approximate initial motion trajectory of the vehicle. Exemplarily, according to the target positioning signal of the vehicle, the first driving path of the vehicle can be predicted as from the company to home. It should be noted that if it is later shown according to the target positioning signal of the vehicle that the vehicle is not from the company to home, but from the company to the mall, the first driving path needs to be switched from the company to home to from the company to the mall.

[0061] Step 102: Match the first driving path with multiple common driving paths of the vehicle stored in the common path library respectively to determine the target common driving path. The target common driving path is the common driving path that matches successfully with the first driving path among the multiple common driving paths of the vehicle. The target common driving path corresponds to at least one energy consumption influence factor group, and each energy consumption influence factor group includes at least one energy consumption influence factor;

[0062] In this step, the aforementioned common path library stores multiple common driving paths of the vehicle. These common driving paths may be the driving paths from the company to home or from home to the mall for the vehicle user. Exemplarily, the first driving path is respectively matched with multiple common driving paths of the vehicle stored in the common path library, and it is determined that the target common driving path is the road from the company to home. The aforementioned energy consumption impact factors may include, but are not limited to, environmental temperature, distribution of road traffic lights, weather, and accessory opening conditions (such as whether the air conditioner is turned on). The target common driving path corresponds to at least one group of energy consumption impact factors. Exemplarily, it can be understood that when driving from the company to home on a rainy day with traffic congestion, then rainy day and traffic congestion form a group of energy consumption impact factors; when driving from the company to home on a rainy day with the air conditioner on, then rainy day and air conditioner on form a group of energy consumption impact factors; when driving from the company to home with the air conditioner on and passing through many red lights, then air conditioner on and many red lights form a group of energy consumption impact factors.

[0063] Step 103: Determine a first group of energy consumption impact factors according to the cloud map. The first group of energy consumption impact factors is the group of energy consumption impact factors corresponding to the actual road conditions of the first driving path among the multiple groups of energy consumption impact factors of the target common driving path.

[0064] In this step, the aforementioned cloud map is a public map, and the map information it contains is relatively rough compared with the in-vehicle map. However, it can generally determine some basic actual road conditions when driving from the company to home at this time. Then, according to these basic actual road conditions, a first group of energy consumption impact factors is determined. Exemplarily, it can be determined that the first group of energy consumption impact factors is rainy day and traffic congestion.

[0065] Step 104: Determine the energy consumption corresponding to the first group of energy consumption impact factors according to the basic energy consumption of the vehicle on the first driving path and the weighting coefficients of the respective energy consumption impact factors in the first group of energy consumption impact factors.

[0066] In this step, the basic energy consumption of the vehicle under the first driving path can be understood as the minimum energy consumption required for the vehicle to complete the mileage of the first driving path without being affected by the above-mentioned various energy consumption influencing factors. Exemplarily, the energy consumption required for the vehicle to complete the mileage of the first driving path on a sunny day and without road congestion can be used as the basic energy consumption of the vehicle. For example, when the basic energy consumption of the vehicle from the company to home is 12.7 kWh, if the above-mentioned first energy consumption influencing factor group includes two energy consumption influencing factors, namely rainy days and road congestion, and the weighting coefficient for rainy days can be 1.07 and the weighting coefficient for road congestion can be 1.3, then it is determined that the energy consumption from the company to home on a rainy day and with road congestion is 12.7*(1 + 0.3 + 0.07).

[0067] Step 105: Predict the cruising range of the vehicle according to the energy consumption corresponding to the first energy consumption influencing factor group and the remaining discharge capacity of the vehicle battery.

[0068] In this step, according to the energy consumption corresponding to the first energy consumption influencing factor group and the remaining discharge capacity of the vehicle battery, the cruising range of the vehicle can be predicted. The aforementioned cruising range can be understood as the maximum distance that the vehicle can still travel.

[0069] The cruising range prediction method of the embodiments of the present application determines the target common driving path in the common path library that matches the first driving path, and then predicts the cruising range of the vehicle according to the energy consumption corresponding to the first energy consumption influencing factor group of the target common driving path. Even if the vehicle does not turn on the navigation, the cruising range of the vehicle can be predicted, thereby expanding the application scenarios of the cruising range prediction method.

[0070] Optionally, before predicting the first driving path of the vehicle according to the target positioning signal of the vehicle when the navigation system of the vehicle is turned off, the method further includes:

[0071] Collect a plurality of positioning signals of the vehicle;

[0072] Determine the driving path of the vehicle and the energy consumption influencing factor group corresponding to the driving path according to the plurality of positioning signals of the vehicle and the cloud map;

[0073] Store the driving path, the energy consumption influencing factor group corresponding to the driving path, and the energy consumption under the energy consumption influencing factor group corresponding to the driving path into the common path library.

[0074] In the driving range prediction method of the embodiment of the present application, it is necessary to form a common path library according to the driving records of the vehicle. First, continuously collect multiple positioning signals uploaded by the vehicle to the cloud. According to the multiple positioning signals of the vehicle, determine the driving path of the vehicle at a certain time, and then determine the energy consumption impact factor group corresponding to the driving path according to the map information of the cloud map. Then store the driving path, the energy consumption impact factor group corresponding to the driving path, and the energy consumption under the energy consumption impact factor group corresponding to the driving path into the common path library. Exemplarily, the driving path of the vehicle this time is from home to the mall, and the energy consumption impact factor group corresponding to this time from home to the mall can be that there are many red lights, the air conditioner is on, and the road is congested. After the vehicle completes this driving path, record the energy consumption of the vehicle under this energy consumption impact factor group. By storing the driving path of the vehicle, the energy consumption impact factor group corresponding to the driving path, and the energy consumption under the energy consumption impact factor group corresponding to the driving path into the common path library, when the vehicle experiences the same driving process again, the energy consumption of the vehicle can be predicted more accurately.

[0075] Optionally, after storing the driving path, the energy consumption impact factor group corresponding to the driving path, and the energy consumption under the energy consumption impact factor group corresponding to the driving path into the common database, the method further includes:

[0076] When multiple energy consumption impact factor groups corresponding to the driving path are stored in the common path library, determine the weighting coefficients of each energy consumption impact factor in the energy consumption impact factor group respectively according to the energy consumption corresponding to the multiple energy consumption impact factor groups;

[0077] Store the weighting coefficients into the common path library.

[0078] In the driving range prediction method of the embodiment of the present application, if a certain driving path is stored in the common path library multiple times, it means that the vehicle has a high driving frequency on this driving path. Then this driving path needs to be analyzed emphatically. Each time the vehicle drives on this driving path, it will obtain a corresponding energy consumption impact factor group. By respectively determining the energy consumption corresponding to multiple energy consumption impact factor groups, the weighting coefficients of each energy consumption impact factor in the energy consumption impact factor group are determined.

[0079] Exemplarily, by the energy consumption from the company to home on a rainy day with road congestion, the energy consumption from the company to home on a rainy day with the vehicle air conditioner on, and the energy consumption from the company to home with the air conditioner on and passing through many red lights, the weighting factor for rainy days, the weighting factor for road congestion, the weighting factor for air conditioner turning on, and the weighting factor for passing through many red lights can be determined. At the same time, it should be noted that the weight of this driving route can also be increased during route matching by recording the number of times this driving route is traveled in the common route library. The remaining driving range prediction method in the embodiments of the present application performs weighted statistics on each energy consumption impact factor in the energy consumption factor group, which is beneficial to improving the accuracy of the next energy consumption prediction for the vehicle driving route.

[0080] Optionally, the predicting the first driving route of the vehicle according to the target positioning signal of the vehicle includes:

[0081] When the navigation system of the vehicle is turned off, predicting the first driving route of the vehicle according to the target positioning signal of the vehicle;

[0082] The method further includes:

[0083] When the navigation system is started, obtaining a second energy consumption impact factor group according to the in-vehicle map corresponding to the navigation system, where the second energy consumption impact factor group is the energy consumption impact factor group of the second driving route of the vehicle, and the second driving route is the driving route of the vehicle planned by the navigation system;

[0084] Predicting the remaining driving range of the vehicle according to the energy consumption corresponding to the second energy consumption impact factor group and the remaining discharge capacity of the vehicle battery.

[0085] In the remaining driving range prediction method in the embodiments of the present application, when the navigation system of the vehicle is turned off, the specific driving route of the vehicle cannot be known through the navigation system, so the first driving route of the vehicle can be predicted according to the target positioning signal of the vehicle; when the navigation system of the vehicle is turned on, the driving route planned by the navigation system for the vehicle can be directly determined as the second driving route, and then the second energy consumption factor group corresponding to the second driving route can be determined through the in-vehicle map corresponding to the navigation system. Then, according to the energy consumption corresponding to the second energy consumption impact factor group and the remaining discharge capacity of the vehicle, the remaining driving range of the vehicle is predicted. The remaining driving range prediction method in the embodiments of the present application directly determines the energy consumption of the vehicle through the navigation system, which is beneficial to quickly predicting the remaining driving range of the vehicle.

[0086] Optionally, after predicting the remaining driving range of the vehicle according to the energy consumption corresponding to the first energy consumption impact factor group and the remaining discharge capacity of the vehicle battery, the method further includes:

[0087] When the first driving route fails to match all of the multiple common driving routes of the vehicle, and the historical driving mileage of the vehicle is greater than or equal to the first driving mileage, the remaining driving mileage of the vehicle is predicted according to the energy consumption corresponding to the historical driving mileage of the vehicle and the remaining discharge capacity of the vehicle battery.

[0088] In the remaining driving mileage prediction method of the embodiments of the present application, if the first driving route fails to match all of the multiple common driving routes of the vehicle, then it is impossible to predict the energy consumption of the vehicle through the common route library, and further predict the remaining driving mileage of the vehicle. At this time, if the vehicle has traveled a certain mileage, the future energy consumption of the vehicle can be predicted through the energy consumption of the vehicle during the historical driving mileage. It should be noted that, in order to make the energy consumption of the vehicle during the historical driving mileage have certain reference, the historical driving mileage of the vehicle can be restricted to be greater than or equal to the first driving mileage, and the specific value of the first driving mileage can be determined according to the actual application situation. The remaining driving mileage prediction method of the embodiments of the present application predicts the future energy consumption of the vehicle through the energy consumption of the vehicle during the historical driving mileage, which is beneficial to further expanding the application scenarios of the remaining driving mileage prediction method.

[0089] Optionally, the method further includes:

[0090] When the historical driving mileage of the vehicle is less than the first driving mileage, the remaining driving mileage of the vehicle is predicted according to the standard energy consumption of the vehicle and the remaining discharge capacity of the vehicle battery.

[0091] In the remaining driving mileage prediction method of the embodiments of the present application, when the historical driving mileage of the vehicle is less than the first driving mileage, it indicates that the historical driving mileage of the vehicle has no reference, then the remaining driving mileage of the vehicle is predicted according to the standard energy consumption of the vehicle. The aforementioned standard energy consumption of the vehicle refers to the energy consumption of the vehicle under the specified vehicle speed according to the performance of the vehicle itself. The remaining driving mileage prediction method of the embodiments of the present application predicts the remaining driving mileage of the vehicle according to the standard energy consumption of the vehicle, which is beneficial to further expanding the application scenarios of the remaining driving mileage prediction method.

[0092] See Figure 2, in the remaining driving range prediction method of the embodiments of the present application, first, if the navigation is turned on, the remaining driving range of the vehicle is predicted by the energy consumption of the second driving path planned by the navigation; if the navigation is not turned on, first, the driving path of the vehicle is predicted as the first driving path, then a target common driving path that matches the first driving path is found from the common path library, and then the remaining driving range of the vehicle is predicted by the energy consumption of the target common driving path; if no matching information is found in the common path library, the remaining driving range of the vehicle is predicted by the energy consumption of the vehicle's historical driving mileage; if the energy consumption of the vehicle's historical driving mileage is not referenceable, the remaining driving range of the vehicle is predicted by the standard energy consumption of the vehicle. The remaining driving range prediction method of the embodiments of the present application takes into account various situations that occur during prediction, further expanding the application scenarios of the remaining driving range prediction method.
