Description

Technical Field

[0001] This application belongs to the field of intelligent vehicle technology, and in particular relates to a self-learning method for vehicle operation mode, terminal equipment, and vehicle. Background Technology

[0002] As vehicles evolve, people have increasingly higher demands for their level of intelligence. Currently, users need to manually adjust the vehicle's operating mode by pressing buttons or keypads. Due to the low level of automation, if a user frequently travels along a fixed route, such as their commute, they need to manually adjust the vehicle's operating mode each time they pass that route. The vehicle cannot automatically determine the operating mode frequently used by the user on that route, and therefore cannot automatically switch operating modes. Summary of the Invention

[0003] This application provides a self-learning method for vehicle operation modes, a terminal device, and a vehicle, which can solve the problem that the vehicle cannot automatically determine the operation mode frequently used by the user in the road section that has been passed, and the vehicle cannot complete the automatic switching of operation modes.

[0004] In a first aspect, embodiments of this application provide a self-learning method for a vehicle's operating mode, comprising:

[0005] Obtain the target route traveled by the vehicle within a historical time period and the set of various operating modes corresponding to the target route, wherein the set of operating modes is the set of historical operating modes used by the vehicle when it travels through each segment of the target route once;

[0006] Based on the historical operating modes in each of the aforementioned operating mode sets, the optimal operating mode corresponding to the target route is determined;

[0007] The target route and the corresponding optimal operating mode are stored, wherein the optimal operating mode corresponding to the target route is used when the vehicle passes through the target route again.

[0008] In one feasible approach, determining the optimal operating mode corresponding to the target route based on historical operating modes from each of the sets of operating modes includes:

[0009] Based on the historical operating modes in each of the operating mode sets, the commonly used operating mode is determined each time the vehicle passes through the target route. The commonly used operating mode is the historical operating mode that appears most frequently or has a frequency greater than a preset frequency in one of the operating mode sets.

[0010] Based on the common operating modes used by the vehicle each time it passes the target route, the optimal operating mode of the target route is determined. The optimal operating mode is the common operating mode that appears more than a preset number of times or has the highest number of occurrences. The optimal operating mode includes power mode and / or driving mode.

[0011] In one implementable manner, before determining the commonly used operating mode for each time the vehicle passes the target route based on historical operating modes in each of the respective sets of operating modes, the method further includes:

[0012] The system searches for a first route among the various routes traveled by the vehicle within the historical time period, wherein the first route is a route that overlaps with the target route.

[0013] Accordingly, determining the commonly used operating mode for each vehicle passing the target route based on historical operating modes in each of the sets of operating modes includes:

[0014] If the first route is not among the routes, the common operating mode used by the vehicle each time it passes the target route is determined based on the historical operating modes in each set of operating modes.

[0015] In one possible implementation, after checking whether a first route exists among the various routes traveled by the vehicle within the historical time period, the method further includes:

[0016] If the first route exists in each of the routes and the first route is a part of the target route, based on the historical operating modes in each set of operating modes, determine the historical operating mode used by the vehicle each time it travels the first segment and the historical operating mode used by the vehicle each time it travels the second segment, wherein the first segment is the overlapping segment of the target route with the first route, and the second segment is the non-overlapping segment of the target route with the first route;

[0017] Obtain the historical operating mode used by the vehicle each time it travels the first route;

[0018] Based on the historical operating modes used by the vehicle each time it travels the first road segment and the historical operating modes used by the vehicle each time it travels the first route, the first optimal operating mode corresponding to the first road segment is determined;

[0019] Based on the historical operating mode used by the vehicle each time it travels the second road segment, a second optimal operating mode corresponding to the second road segment is determined, wherein the first optimal operating mode corresponding to the first road segment and the second optimal operating mode constitute the optimal operating mode corresponding to the target route.

[0020] In one feasible approach, determining the first optimal operating mode corresponding to the first road segment based on the historical operating modes used by the vehicle each time it travels the first road segment and the historical operating modes used by the vehicle each time it travels the first route includes:

[0021] Find the historical operating mode that appears most frequently in the target mode set, wherein the target mode set includes the historical operating mode used by the vehicle each time it travels the first road segment and the historical operating mode used by the vehicle each time it travels the first route;

[0022] The historical operating mode that appears most frequently in the target mode set is recorded as the first optimal operating mode corresponding to the first road segment.

[0023] In one possible implementation, after checking whether a first route exists among the target routes traveled by the vehicle within the historical time period, the method further includes:

[0024] If the first route exists among the various routes and the target route is a section of the first route, obtain the historical operating mode used by the vehicle each time it travels the target section, wherein the target section is a section of the first route that overlaps with the target route;

[0025] Based on the historical operating modes used by the vehicle each time it travels the target road segment and the historical operating modes in each set of operating modes, the optimal operating mode corresponding to the target route is determined.

[0026] In one possible implementation, after storing the target route and the optimal operating mode corresponding to the target route, the method further includes:

[0027] Obtain the vehicle's current navigation route;

[0028] The key location points in the current navigation route are compared with the key location points in the pre-stored target route to obtain the comparison results;

[0029] If the comparison result indicates that the routes are consistent, the optimal operating mode corresponding to the target route is obtained;

[0030] The vehicle's movement is controlled based on the optimal operating mode corresponding to the target route.

[0031] In one feasible embodiment, before controlling the vehicle's movement based on the optimal operating mode corresponding to the target route, the method further includes:

[0032] Based on the type of optimal operating mode, the current state of the vehicle is obtained. When the type of optimal operating mode is power mode and driving mode, the current state includes the remaining energy value of the power output device and the fault state of the target component in the vehicle. The target component is the component that needs to be used when switching driving modes.

[0033] Accordingly, controlling the vehicle's movement based on the optimal operating mode corresponding to the target route includes:

[0034] If the current state meets the preset requirements, the vehicle is controlled to drive based on the optimal operating mode corresponding to the target route. The preset requirements include that the remaining energy value is greater than the first preset threshold corresponding to the power mode and that the target component is in a non-faulty state.

[0035] Secondly, embodiments of this application provide a self-learning device for vehicle operating modes, comprising:

[0036] The data acquisition module is used to acquire the target route traveled by the vehicle within a historical time period and the set of various operating modes corresponding to the target route, wherein the set of operating modes is the set of historical operating modes used by the vehicle when it travels through each segment of the target route once.

[0037] The data processing module is used to determine the optimal operating mode corresponding to the target route based on the historical operating modes in each of the operating mode sets;

[0038] The data storage module is used to store the target route and the optimal operating mode corresponding to the target route, wherein the optimal operating mode corresponding to the target route is used when the vehicle passes through the target route again.

[0043] The beneficial effects of the first aspect of this application compared to the prior art are: obtaining the target route traveled by the vehicle within a historical time period and the corresponding set of operating modes, wherein the set of operating modes is a set of historical operating modes used by the vehicle when traveling through each segment of the target route; determining the optimal operating mode corresponding to the target route based on the historical operating modes in each set of operating modes; and storing the target route and the optimal operating mode corresponding to the target route.

[0056] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment.

[0058] Currently, to meet user needs, vehicles are equipped with multiple power modes and driving modes, which can both be referred to as vehicle operating modes. Users can freely combine power modes and driving modes to satisfy different driving experiences.

[0059] The power mode primarily controls the vehicle's power output method. The driving mode primarily controls the vehicle's driving style. For hybrid vehicles, power modes can include pure electric mode, hybrid mode, and pure gasoline mode; driving modes can include standard mode, sport mode, and economy mode. In pure electric mode, the battery is the power output device, and the vehicle consumes electrical energy. In hybrid mode, the vehicle consumes both electrical energy and fuel; the battery and fuel system are the power output devices. In pure gasoline mode, the fuel system is the power output device, and the vehicle consumes fuel. In sport mode, fuel consumption increases, and the vehicle's power increases. In economy mode, fuel consumption decreases, and the vehicle's power decreases. In standard mode, fuel consumption and power are between those of sport and economy modes.

[0060] Users often travel the same routes when using vehicles; for example, commuters frequently take the same roads to and from get off work. Having to manually adjust the vehicle's power and driving modes each time they travel a certain distance causes inconvenience.

[0061] For the reasons mentioned above, this application first uses the historical operating modes used by vehicles when traversing the target route within a historical time period to perform self-learning, in order to determine the optimal operating mode corresponding to the target route. Then, it pre-stores routes frequently traveled by users and the corresponding optimal operating modes. When a user traverses a stored route again, the vehicle can automatically drive according to the pre-stored optimal operating mode without the user having to manually adjust the vehicle's operating mode, thus achieving automatic switching of the vehicle's operating mode.

[0062] Figure 1 A schematic flowchart illustrating the self-learning method for vehicle operating modes provided in this application is shown. This method can be applied to the vehicle's central control equipment and / or cloud server. (Refer to...) Figure 1 The method is described in detail below:

[0063] S201, obtain the target route traveled by the vehicle within a historical time period and the set of various operating modes corresponding to the target route, wherein the set of operating modes is the set of historical operating modes used by the vehicle when traveling through each segment of the target route once.

[0064] In this embodiment, each route traversed by the vehicle within a historical time period can be recorded as a target route. The vehicle may traverse the same target route multiple times within a historical time period, and may use multiple historical operating modes during a single traversal of the target route (i.e., different historical operating modes were used on different road segments). All historical operating modes used during a single traversal of the target route are combined to obtain an operating mode set. Historical operating modes include power modes and / or driving modes.

[0065] For example, when a vehicle passes the target route for the first time, the historical operating patterns it uses in chronological order are A, B, A, and C. A, B, A, and C form a set of operating patterns. When the vehicle passes the target route for the second time, the historical operating patterns it uses in chronological order are B, B, C, and A. B, B, C, and A form a set of operating patterns.

[0066] S202, Based on the historical operating modes in each of the sets of operating modes, determine the optimal operating mode corresponding to the target route.

[0067] In this embodiment, the historical operating mode that appears most frequently in the set of all operating modes is found, and the historical operating mode that appears most frequently is determined as the optimal operating mode for the target route.

[0068] Alternatively, find historical operating modes in the set of all operating modes with a probability greater than a preset probability, and determine the historical operating modes with a probability greater than the preset probability as the optimal operating modes for the target route.

[0069] As an example, as shown in Table 1 below, the historical operating modes used when the vehicle first traveled the target route were: Mode 2, Mode 1, Mode 1, Mode 1, and Mode 1; the historical operating modes used when the vehicle traveled the target route for the second time were: Mode 1, Mode 2, Mode 1, Mode 3, and Mode 1. From the historical operating modes used in the two trips to the target route, it can be seen that Mode 1 was used the most times. Therefore, Mode 1 is considered the optimal operating mode for the target route.

[0070] Table 1 shows the historical operating modes used when the vehicle traveled the target route twice.

[0071] First drive Mode 2 Mode 1 Mode 1 Mode 1 Mode 1 Second trip Mode 1 Mode 2 Mode 1 Mode 3 Mode 1

[0072] In this embodiment of the application, the optimal operating mode of the target route is determined based on the historical operating mode used within a historical time period, so that the obtained optimal operating mode is more accurate.

[0073] S203, store the target route and the optimal operating mode corresponding to the target route, wherein the optimal operating mode corresponding to the target route is used when the vehicle passes through the target route again.

[0074] In this embodiment, the target route traveled by the vehicle within a historical time period and the corresponding set of operating modes are obtained. The set of operating modes represents the historical operating modes used by the vehicle when traversing each segment of the target route. Based on the historical operating modes in each set, the optimal operating mode corresponding to the target route is determined. The target route and its optimal operating mode are stored, whereby the optimal operating mode is used to control vehicle movement. This application determines the optimal operating mode for a target road segment based on the historical operating modes used during the passage of that segment within a historical time period. This allows the optimal operating mode to be used to control vehicle movement when the vehicle passes through the target road segment again, eliminating the need for manual switching of the vehicle's operating mode by the user, achieving automated switching of operating modes, and improving the vehicle's automation level.

[0075] like Figure 2 As shown, in one possible implementation, step S202 may include:

[0076] S2021, based on the historical operating modes in each of the operating mode sets, determine the commonly used operating mode each time the vehicle passes through the target route, wherein the commonly used operating mode is the historical operating mode that appears most frequently or has a frequency greater than a preset frequency in the operating mode set.

[0077] In this embodiment, for each set of operating modes, the historical operating modes that appear most frequently or whose frequency exceeds a preset frequency are found to obtain the commonly used operating modes in each set. The preset frequency can be set as needed.

[0078] For example, if the historical operating modes in operating mode set 1 are A, B, A, and C, then the commonly used operating mode in operating mode set 1 is A. If the historical operating modes in operating mode set 2 are A, B, B, and C, then the commonly used operating mode in operating mode set 2 is B.

[0079] S2022, Based on the common operating mode used by the vehicle each time it passes the target route, determine the optimal operating mode of the target route, wherein the optimal operating mode is the common operating mode that appears more than a preset number of times or appears the most frequently.

[0080] In this embodiment, if a commonly used operating mode appears more than a preset number of times or appears the most times, then the commonly used operating mode is determined to be the operating mode frequently used by the vehicle when passing through the target route. The operating mode is stored so that when the user passes through the target route again, the vehicle can be directly switched to the user's commonly used operating mode.

[0081] For example, if the common operating mode in operating mode set 1 is A; the common operating mode in operating mode set 2 is B; the common operating mode in operating mode set 3 is A; and the common operating mode in operating mode set 4 is A, then the common operating mode A appears more than the preset number of times 2, so the common operating mode A is the optimal operating mode.

[0082] In one possible implementation, there may be sections of the route that overlap with the target route in the historical time period. Therefore, in order to make the optimal operation mode of the determined target route more accurate, it is also necessary to consider the historical operation mode of the routes that overlap with the target route.

[0083] Specifically, prior to step S2021, the above method may further include:

[0084] S301, search for whether a first route exists among the various routes traveled by the vehicle within the historical time period, wherein the first route is a route that overlaps with the target route.

[0085] Accordingly, step S2021 may specifically include: if the first route does not exist in each route, determining the common operating mode used by the vehicle each time it passes the target route based on the historical operating modes in each set of operating modes.

[0086] In this embodiment, there may be multiple routes traveled by vehicles within a historical time period, and there may be overlapping sections among these routes. For overlapping sections, the operating mode used by the vehicle each time it passes through the overlapping section is comprehensively considered to determine the common operating mode used by the vehicle in the overlapping section, so that the optimal operating mode of the obtained route is more accurate. Therefore, before determining the optimal operating mode corresponding to the target route, it is first determined whether there are any overlapping sections of the target route with other routes.

[0087] For example, such as Figure 3 As shown, the target route is route 1. The road segment L in target route 1 and route L in route 2 are overlapping road segments. In this application, road segment L is referred to as the first road segment.

[0088] In this embodiment, if the first route does not exist in the route, the operating modes on other routes do not need to be considered. The common operating mode of the target route can be determined directly based on the historical operating mode used when the vehicle travels the target route.

[0089] like Figure 4 As shown, in one possible implementation, after step S301, the above method may further include:

[0090] S401, if the first route exists among the various routes and the first route is a part of the target route, based on the historical operating modes in each of the operating mode sets, determine the historical operating mode used by the vehicle each time it travels the first route and the historical operating mode used by the vehicle each time it travels the second route, wherein the first route is the overlapping route with the first route in the target route, and the second route is the non-overlapping route with the first route in the target route.

[0091] In this embodiment, if the first route is a section of the target route, in order to take into account the historical operation mode used by the first route in the target route, the target route is divided into two parts: one part is the section that overlaps with the first route, and the other part is the section that does not overlap with the first route.

[0092] There can be one or more first road segments, and there can also be one or more second road segments.

[0093] The operation mode set stores the historical operation modes used when the vehicle travels on each segment of the target route. Therefore, after the target route is segmented, the historical operation mode corresponding to each segment of the target route can be determined based on the operation mode set.

[0094] For example, if the first road segment is segment D, and the historical operating modes used by the vehicle when traveling on the first road segment are recorded in the operating mode set as A and B, then according to the operating mode set, it can be determined that the historical operating modes used by the vehicle when traveling on the first road segment are A and B.

[0095] S402, Obtain the historical operating mode used by the vehicle each time it travels the first route.

[0096] In this embodiment, the historical operating mode used by the vehicle for each route is recorded. Therefore, the historical operating mode corresponding to the first route can be obtained by searching the recorded information.

[0097] S403, based on the historical operating mode used by the vehicle each time it travels the first road segment and the historical operating mode used by the vehicle each time it travels the first route, determine the first optimal operating mode corresponding to the first road segment.

[0098] In this embodiment, the specific implementation method of step S403 may include: finding the historical operating mode that appears most frequently in the target mode set, wherein the target mode set includes the historical operating mode used by the vehicle each time it travels the first road segment and the historical operating mode used by the vehicle each time it travels the first route; and recording the historical operating mode that appears most frequently in the target mode set as the first optimal operating mode corresponding to the first road segment.

[0099] By integrating the historical operating patterns used by the vehicle each time it travels the first route and the historical operating patterns used by the vehicle each time it passes through the first road segment, the historical operating pattern used most frequently by the vehicle is determined.

[0100] For example, if the historical operating modes used by a vehicle when passing through the first route are A, B, A, A, and A respectively; and the historical operating modes used by a vehicle when passing through the first road segment are B, C, A, A, then the historical operating mode A is used the most. Therefore, historical operating mode A is recorded as the first optimal operating mode corresponding to the first road segment.

[0101] In this embodiment, the specific implementation method of step S403 may further include: determining the first commonly used operating mode used by the vehicle each time it passes through the first road segment. The first commonly used operating mode is the historical operating mode that the vehicle uses the most times or has a usage frequency greater than a preset frequency when passing through the first road segment once.

[0102] Determine the second most frequently used operating mode for each time the vehicle passes through the first route. The second most frequently used operating mode is the historical operating mode that the vehicle uses most often or has a usage frequency greater than the preset frequency when passing through the first route once.

[0103] The first optimal operating mode is determined from each of the first and second most common operating modes. The first optimal operating mode is the most frequently occurring or the most frequently occurring operating mode.

[0104] S404, based on the historical operating mode used by the vehicle each time it travels the second road segment, determine the second optimal operating mode corresponding to the second road segment, wherein the first optimal operating mode corresponding to the first road segment and the second optimal operating mode constitute the optimal operating mode corresponding to the target route.

[0105] In this embodiment, the second optimal operating mode corresponding to the second road segment is determined using the method described in S403 above, which will not be repeated here.

[0106] As an example, as shown in Table 2 below, the historical operating mode used when a vehicle first passes through the first second segment (position 1 to position 2) of the pre-stored road segment is: Mode 2, Mode 1, Mode 1, Mode 1; the historical operating mode used when passing through the second second segment (position 3 to position 4) is: Mode 1, Mode 2, and Mode 2; and the historical operating mode used when passing through the first segment (from position 2 to position 3) is: Mode 1, Mode 2, Mode 2, Mode 2. The historical operating mode used when a vehicle passes through the first second segment (position 1 to position 2) of the pre-stored road segment for the second time is: Mode 1, Mode 2, Mode 1, Mode 1; the historical operating mode used when passing through the second second segment (position 3 to position 4) is: Mode 1, Mode 2, and Mode 2; and the historical operating mode used when passing through the first segment is: Mode 2, Mode 1, Mode 2, Mode 2.

[0107] The historical operating modes used by the vehicle when passing through the first route are: Mode 2, Mode 2, Mode 1, Mode 2.

[0108] Table 2 Historical Operating Modes Used for Vehicle Target Routes and Route 1

[0109]

[0110] As shown in Table 2 above, in the second road segment (location 1 to location 2), vehicles used mode 1 more often. Therefore, historical operation mode 1 is taken as the second optimal operation mode for the second road segment (location 1 to location 2).

[0111] In the second road segment (positions 3 to 4), vehicles used mode 2 more frequently. Therefore, historical operating mode 2 is selected as the second optimal operating mode for the second road segment (positions 3 to 4).

[0112] In the first segment, vehicles used mode 2 more frequently. Therefore, historical operating mode 2 was selected as the first optimal operating mode for the first segment.

[0113] Therefore, the optimal operating modes corresponding to the pre-stored road segments are as follows: the optimal operating mode for the second road segment (location 1 to location 2) is 1, the optimal operating mode for the first road segment is 2, and the optimal operating mode for the second road segment (location 3 to location 4) is 2.

[0114] In this embodiment, since both the first road segment and the second road segment are road segments on the target route, the first optimal operating mode corresponding to the first road segment and the second optimal operating mode corresponding to the second road segment are both the optimal operating modes corresponding to the target route. When obtaining the optimal operating mode corresponding to the target route, it is necessary to obtain the first optimal operating mode corresponding to the first road segment and the second optimal operating mode corresponding to the second road segment; the vehicle uses the first optimal operating mode when traveling on the first road segment and the second optimal operating mode when traveling on the second road segment.

[0115] like Figure 5 As shown, in one possible implementation, after step S301, the above method may further include:

[0116] S501, if the first route exists among the various routes and the target route is a section of the first route, obtain the historical operating mode used by the vehicle each time it travels the target section, wherein the target section is a section of the first route that overlaps with the target route.

[0117] In this embodiment, if the target route is a section of the first route, it is necessary to obtain the historical operation mode of the sections of the first route that overlap with the target route, so as to determine the optimal operation mode of the target route based on the historical operation mode of the sections of the first route that overlap with the target route.

[0118] S502, based on the historical operating modes used by the vehicle each time it travels the target road segment and the historical operating modes in each set of operating modes, determine the optimal operating mode corresponding to the target route.

[0119] In this embodiment, the specific implementation of step S502 is the same as that of step S403 above. Please refer to the description of step S403 above, which will not be repeated here.

[0120] like Figure 6 As shown, after step S203, the above method may further include:

[0121] S101, Obtain the vehicle's current navigation route.

[0122] In this embodiment, the current navigation route has a starting position and an ending position. The current navigation route may also have intermediate positions, which are the positions between the starting and ending positions. The current navigation route is the route set by the user.

[0123] When this application is used in a cloud server, the vehicle needs to send the current navigation route to the cloud server, and the cloud server needs to receive the current navigation route sent by the vehicle.

[0124] S102, compare the key location points in the current navigation route with the key location points in the pre-stored target route to obtain the comparison result.

[0125] In this embodiment, the comparison result can be either the routes are consistent or the routes are inconsistent.

[0126] The target routes are pre-stored routes frequently traveled by users. Each target route and its corresponding optimal operating mode are pre-stored. Target routes are determined based on routes traveled by vehicles within a historical time period. The optimal operating mode for each target route is determined based on the operating mode used by vehicles traversing the target route within a historical time period.

[0127] In this embodiment, each target route and its corresponding optimal operating mode can be stored in the form of a table. The optimal operating mode can be represented by numbers, letters, or Chinese characters. For example, if the optimal operating mode is represented by numbers, then each number represents an operating mode.

[0128] S103, if the comparison result is that the routes are consistent, obtain the optimal running mode corresponding to the target route.

[0129] S104, control the vehicle's movement based on the optimal operating mode corresponding to the target route.

[0130] In this embodiment, after obtaining the optimal operating mode, the vehicle is switched to the optimal operating mode so that the vehicle can drive in the optimal operating mode.

[0131] If this application is applied to a cloud server, the cloud server can send the optimal operating mode to the vehicle so that the vehicle can drive based on the optimal operating mode.

[0132] If there are multiple optimal operating modes corresponding to the target route, then the vehicle's movement is controlled based on any one of the optimal operating modes.

[0133] In this embodiment, the vehicle's current navigation route is first obtained. If the current navigation route is the target route, the optimal operating mode corresponding to the target route is obtained, and then the optimal operating mode corresponding to the target route is used. This application can determine the required operating mode based on the vehicle's current navigation route while the vehicle is in motion, and then control the vehicle's movement according to the determined operating mode. This application eliminates the need for the user to manually adjust the operating mode, achieving automatic adjustment of the vehicle's operating mode and improving the vehicle's automation level.

[0134] In one possible implementation, after obtaining the optimal operating mode, it is also necessary to check the vehicle's current state to determine whether the vehicle can switch to the optimal operating mode at the current moment. Specifically, before step S103, the above method may further include:

[0135] Based on the type of optimal operating mode, the current state of the vehicle is obtained. When the type of optimal operating mode is power mode and driving mode, the current state includes the remaining energy value of the power output device and the fault state of the target component in the vehicle. The target component is the component that needs to be used when switching driving modes.

[0136] Accordingly, step S103 may specifically include:

[0137] If the current state meets the preset requirements, the vehicle is controlled to drive based on the optimal operating mode corresponding to the target route. The preset requirements include that the remaining energy value is greater than the first preset threshold corresponding to the power mode and that the target component is in a non-faulty state.

[0138] In this embodiment, when the optimal operating mode is power mode, only the remaining energy value of the power output device in the vehicle needs to be acquired. When the optimal operating mode is driving mode, only the fault status of the target component in the vehicle needs to be acquired.

[0139] When obtaining the remaining energy value of the power output device, the remaining energy value of the corresponding device can also be obtained according to the type of power mode. For example, if the power mode is pure electric mode, the remaining battery charge is obtained; if the power mode is pure gasoline mode, the remaining fuel of the gasoline device is obtained; if the power mode is hybrid mode, the remaining battery charge and the remaining fuel of the gasoline device are obtained.

[0140] The target components may include the vehicle's ESP (Electronic Stability Program), central control equipment, engine controller, and transmission controller.

[0141] In this embodiment, the vehicle's current state can be used to determine whether the vehicle can switch to the optimal operating mode at the current moment. If the current state meets the preset requirements, it means that the vehicle can switch to the optimal operating mode and can drive according to the optimal operating mode. If the current state does not meet the preset requirements, it means that the vehicle cannot switch to the optimal operating mode, and the optimal operating mode can be ignored and driving can continue according to the currently used operating mode; or the automatic switching of operating modes can be exited, allowing the user to switch to the desired operating mode manually.

[0142] Specifically, if the remaining energy value is greater than the first preset threshold corresponding to the power mode, it means that the remaining energy in the vehicle can support that power mode. For example, if the power mode is pure electric mode and the remaining battery level is 60%, which is greater than the first threshold, then the remaining energy value is determined to be greater than the first preset threshold corresponding to the power mode, and the vehicle can operate in pure electric mode. The first preset threshold includes the first threshold value. If the power mode is pure gasoline mode and the remaining fuel level is 30%, which is greater than the second threshold value, then the remaining energy value is determined to be greater than the first preset threshold corresponding to the power mode, and the vehicle can operate in pure gasoline mode. The first preset threshold includes the second threshold value. Both the first and second threshold values ​​can be set as needed.

[0143] In this embodiment of the application, when switching the vehicle's operating state to the optimal operating mode, the current state of the vehicle is detected first, and the vehicle's operating mode is determined based on the current state. This makes the automatic switching of the operating mode more consistent with the current state of the vehicle, and makes the switching of the operating mode more accurate.

[0144] In one possible implementation, the above method may further include:

[0145] Each time a vehicle makes a trip, it sends the navigation route and the operating mode used while traveling that route to the cloud server. Navigation routes within a historical time period can be recorded as target routes. The operating mode used by the vehicle to travel the navigation route within a historical time period is recorded as the historical operating mode.

[0146] The cloud server determines the optimal operating mode for the target route based on the historical operating modes used when traversing the target route within a historical time period, and stores the target route and the corresponding optimal operating mode in association. Specifically, the process of determining the optimal operating mode for the target route is described in steps S201 to S203, S301, S401 to S404, S501, and S502 above, and will not be repeated here.

[0147] When a vehicle needs to travel at a given moment, it sends its current navigation route to the cloud server.

[0148] If the cloud server determines that the current navigation route is the target route, the cloud server obtains the optimal operating mode corresponding to the target route and sends the optimal operating mode corresponding to the target route to the vehicle.

[0149] The vehicle controls its movement according to the optimal operating mode corresponding to the target route.

[0150] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
