Description

Technical Field

[0001] This application belongs to the field of information processing technology, and in particular relates to a method, apparatus and terminal equipment for determining when a vehicle is in a desert off-road state. Background Technology

[0002] Currently, determining whether a vehicle is in desert off-road mode generally involves collecting its location information. Specifically, if the vehicle is located in a desert area, it is determined to be in desert off-road mode. However, since the vehicle's location only determines its approximate area and cannot determine whether it is traveling on a desert road or on sandy terrain, determining whether a vehicle is in desert off-road mode based solely on its location is inaccurate. Summary of the Invention

[0003] This application provides a method, apparatus, and terminal device for determining whether a vehicle is in a desert off-road state, which can solve the problem of inaccurate location determination of vehicles in desert off-road state currently in use.

[0004] In a first aspect, embodiments of this application provide a method for determining whether a vehicle is in a desert off-road state, including:

[0005] The vehicle's location information and vehicle parameters during its driving process are obtained, wherein the vehicle parameters include throttle opening and tire pressure value, or the vehicle parameters include the throttle opening.

[0006] When the location information indicates that the vehicle is located in a desert area and the vehicle parameters indicate that the current vehicle status is the same as the preset sand road vehicle status, the vehicle is determined to be in desert off-road mode.

[0007] Secondly, embodiments of this application provide a device for determining whether a vehicle is in a desert off-road state, comprising:

[0008] The vehicle parameter acquisition module is used to acquire the vehicle's location information and vehicle parameters during the vehicle's driving process, wherein the vehicle parameters include throttle opening and tire pressure value, or the vehicle parameters include the throttle opening.

[0009] The status determination module is used to determine that the vehicle is in desert off-road mode when the location information indicates that the vehicle is located in a desert area and the vehicle parameters indicate that the current vehicle status is the same as the preset sand road vehicle status.

[0010] Thirdly, embodiments of this application provide a terminal device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the method for determining that a vehicle is in a desert off-road state as described in any of the first aspects above.

[0011] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the method for determining whether a vehicle is in a desert off-road state as described in any of the first aspects.

[0012] Fifthly, embodiments of this application provide a computer program product that, when run on a terminal device, causes the terminal device to execute the method for determining whether a vehicle is in a desert off-road state as described in any of the first aspects.

[0013] The beneficial effects of the first aspect of this application compared to the prior art are as follows: This application first obtains the vehicle's location information and vehicle parameters. When the location information indicates that the vehicle is located in a desert area, and the vehicle parameters indicate that the current vehicle state is the same as the preset sand road vehicle state, the vehicle is determined to be in a desert off-road state. Since the vehicle's own state is related to the road conditions, the road conditions can be inferred using the vehicle state. This application uses both location information and vehicle parameters to jointly determine that the vehicle is in a desert off-road state. It not only determines that the vehicle is in a desert area from a geographical location, but also determines the road conditions from the vehicle's own state. Compared with the prior art method that only uses the vehicle's location to determine whether the vehicle is in a desert off-road state, this application considers the vehicle's own state during the driving process, making the determination of the desert off-road state more accurate.

[0014] It is understood that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

[0027] 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.

[0028] References to "one embodiment" or "some embodiments" as described 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. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0029] With increasing work pressure, many people choose off-road driving to relax, and desert off-roading is one such method. When users are engaged in desert off-roading, novice drivers may not know how to drive the vehicle effectively. Therefore, if it's confirmed that the vehicle is in desert off-roading mode, driving strategies for desert off-roading can be sent to the vehicle to guide the user through the desert terrain.

[0030] However, since it is not yet possible to accurately determine whether a vehicle is in desert off-road condition, it is not possible to provide driving instructions to users when they are engaged in desert off-roading.

[0031] For the reasons mentioned above, this application proposes a method for determining whether a vehicle is in a desert off-road state. Based on the vehicle's location information and parameters, it can be determined whether the vehicle is in a desert off-road state. Upon determining that the vehicle is in a desert off-road state, a driving strategy for desert off-road driving is sent to the vehicle, enabling the user to better drive the vehicle in the desert according to the driving strategy.

[0032] Figure 1 This is a schematic diagram illustrating an application scenario of the method for determining whether a vehicle is in a desert off-road state, as provided in this application embodiment. The method can be used to determine whether a vehicle is in a desert off-road state.

[0033] The vehicle's location acquisition device 10 collects the vehicle's location information and sends it to the server 20. The vehicle's parameter acquisition device 30 collects vehicle parameters during operation and sends these parameters to the server 20. The server 20 determines whether the vehicle is in desert off-road mode based on the location information and vehicle parameters. If the server 30 determines that the vehicle is in desert off-road mode, it sends the corresponding target driving strategy to the vehicle. Upon receiving the target driving strategy, the vehicle displays it on a display device.

[0034] Or, such as Figure 2 As shown, the vehicle's location acquisition device 10 collects the vehicle's location information and sends it to the vehicle's central processing unit 40. The vehicle's parameter acquisition device 30 collects vehicle parameters during operation and sends these parameters to the central processing unit 40. The central processing unit 40 determines whether the vehicle is in desert off-road mode based on the location information and vehicle parameters. When the central processing unit 40 determines that the vehicle is in desert off-road mode, it displays the target driving strategy via a display device.

[0035] Among them, the vehicle parameters can be the real-time throttle opening during vehicle operation.

[0036] Vehicle parameters can also include real-time throttle opening and tire pressure during vehicle operation.

[0037] The following combination Figure 1 and Figure 2 The method for determining whether a vehicle is in a desert off-road state according to the embodiments of this application will be described in detail. The method of this application can be applied to the server 20 or the central processing unit 40 described above.

[0038] Figure 3 A schematic flowchart illustrating the method for determining whether a vehicle is in desert off-road condition, as provided in this application, is shown below. Figure 3 The method is described in detail below:

[0039] S101, acquire the vehicle's location information and vehicle parameters during the vehicle's driving process, wherein the vehicle parameters include throttle opening and tire pressure value, or the vehicle parameters include the throttle opening.

[0040] In this embodiment, the vehicle's location information can be determined using GPS (Global Positioning System). The vehicle can record and / or send its location information to the server in real time.

[0041] During vehicle operation, the vehicle can also record vehicle parameters in real time and / or send vehicle parameters to the server.

[0042] Vehicle parameters can include throttle opening, tire pressure, vehicle speed, and steering wheel angle. These parameters can be collected by various sensors installed on the vehicle. For example, a pressure sensor can be used to detect tire pressure, and a speed sensor can be used to detect vehicle speed.

[0043] Location information and vehicle parameters are collected at preset time intervals, such as 20 seconds, 30 seconds, or 1 minute.

[0044] S102, when the location information indicates that the vehicle is located in a desert area and the vehicle parameters indicate that the current vehicle status is the same as the preset sand road vehicle status, the vehicle is determined to be in desert off-road status.

[0045] In this embodiment, the vehicle's location is determined in real time based on its location information. Alternatively, the vehicle's location is determined according to a preset determination period.

[0046] The system determines whether a vehicle is in a sandy road condition based on a preset judgment period. This judgment period can be set as needed, for example, to 2 minutes, 3 minutes, or 5 minutes. The judgment period must be longer than the preset time interval.

[0047] In this embodiment, the vehicle's position on a preset map can be determined based on location information, thereby determining whether the vehicle is in a desert area. The preset map has already divided areas into desert, grassland, etc. The vehicle's position on the preset map is determined based on location information. If the vehicle's position on the preset map is within a designated desert area, then the vehicle is determined to be in a desert area. If the vehicle's position on the preset map is not within a designated desert area, then the vehicle is determined not to be in a desert area.

[0048] In this embodiment, vehicle parameters can characterize the current vehicle state. Based on the vehicle parameters collected within the current judgment period, the current vehicle state can be determined. The current vehicle state is compared with the preset sand road vehicle state to determine whether the vehicle is in the sand road vehicle state at the current time. If the vehicle is in the sand road vehicle state, it is determined that the vehicle is currently in desert off-road mode, that is, the vehicle is driving on a sand road.

[0049] Optionally, the vehicle parameters collected within the current judgment period can be input into the neural network discrimination model to determine whether the current vehicle status is the same as the preset sand road vehicle status.

[0050] The vehicle status on sandy roads can include the vehicle's throttle opening, tire pressure, and speed.

[0051] Optionally, first determine whether the vehicle is in a desert area based on the location information. After confirming that the vehicle is in a desert area, then use vehicle parameters to determine whether the vehicle is in a sandy road condition.

[0052] Alternatively, while determining whether a vehicle is in a desert area based on location information, determine whether the vehicle is in a sandy road condition based on vehicle parameters.

[0053] In this embodiment, the vehicle's location information and vehicle parameters are first obtained. When the location information indicates the vehicle is in a desert area and the vehicle parameters indicate the current vehicle state is the same as a preset sand road vehicle state, the vehicle is determined to be in a desert off-road state. Compared to existing technologies that determine a vehicle's desert off-road state solely based on its location, this application, in addition to using location information to determine the vehicle's location in a desert area, further uses vehicle parameters to determine the current vehicle state. Only when the vehicle's current state matches a preset sand road vehicle state is the vehicle determined to be in a desert off-road state. Since the vehicle's own state is related to the road conditions, this application determines the vehicle's desert off-road state based on both vehicle location and vehicle state, considering not only the vehicle's geographical location but also its own state during travel, making the determination of the desert off-road state more accurate.

[0054] In one possible implementation, when it is determined that the vehicle is in a desert off-road condition, the display device on the vehicle is controlled to display the target driving strategy. Alternatively, when it is determined that the vehicle is in a desert off-road condition, the display device on the vehicle is controlled to display both the target driving strategy and the target vehicle maintenance strategy.

[0055] The target vehicle maintenance strategy is a preset vehicle maintenance strategy after the vehicle has been driven in the desert. The target driving strategy is a preset driving strategy corresponding to the vehicle when it is in the desert off-road state. The target driving strategy and the target vehicle maintenance strategy can be determined by the vehicle itself or obtained from the server. The vehicle can also broadcast the target driving strategy through a broadcasting device.

[0056] The vehicle displays a target driving strategy, allowing users to drive the vehicle according to this strategy. The target driving strategy may include speed ranges, throttle control ranges, steering wheel angle control ranges, and available vehicle operating modes. Available operating modes include Sport mode and Fuel mode. In Fuel mode, the engine directly drives the vehicle. In Sport mode, the transmission can shift gears freely, with a delay between shifts, allowing the engine to maintain high speeds for longer periods, resulting in greater torque output and acceleration.

[0057] The vehicle display showcases the target vehicle maintenance strategy, enabling users to perform targeted vehicle maintenance after desert off-roading. This avoids situations where users are unaware of what maintenance is required after desert off-roading, leading to untimely vehicle inspections and impacting vehicle usability.

[0058] In this embodiment, the target vehicle maintenance strategy may include engine inspection, tire inspection, brake system inspection, etc.

[0059] In one possible implementation, after determining that the vehicle is in a desert off-road condition, the system continuously acquires the vehicle's location information and parameters, and continuously determines whether the vehicle is still in a desert off-road condition based on the location information and parameters. If it is determined that the vehicle has left the sandy road and is in a non-desert off-road condition, a target vehicle maintenance strategy is sent to the vehicle.

[0060] In addition, when pushing target vehicle maintenance strategies to users, or when determining that the vehicle is in desert off-road mode, or after the off-roading is completed, the location of the target service station can be displayed through the display device so that users know the location of nearby service stations where their vehicles can be maintained.

[0061] In one possible implementation, the throttle required for driving in the desert is greater than that required for driving in non-desert areas. When driving in the desert, tire pressure needs to be reduced to increase the contact area between the tires and the sand, thus improving the vehicle's traction. Therefore, the vehicle's throttle opening and tire pressure can be used to determine whether it is driving in the desert.

[0062] Specifically, when vehicle parameters include throttle opening and tire pressure, if the vehicle's current tire pressure and throttle position are the same as the preset sand road tire pressure and throttle position, respectively, the vehicle parameters indicate that the current vehicle state is the same as the preset sand road vehicle state. If the vehicle's current tire pressure and throttle position are different from the preset sand road tire pressure and / or the vehicle's current throttle position are different from the preset sand road throttle position, the vehicle parameters indicate that the current vehicle state is different from the preset sand road vehicle state.

[0063] like Figure 4 As shown, after step S101, the method for determining whether the current vehicle state is the same as the vehicle state on the sandy road includes:

[0064] S201, based on the magnitude of the tire pressure value within the current judgment period, determine whether the current tire pressure state of the vehicle is the same as the preset tire pressure state for sandy roads.

[0065] Specifically, the tire pressure values ​​include the first front tire pressure, the second front tire pressure, the first rear tire pressure, and the second rear tire pressure.

[0066] Determine whether the tire pressure values ​​of each first front tire and each second front tire within the current judgment period are within the preset tire pressure range for sandy roads. Also determine whether the tire pressure values ​​of each first rear tire and each second rear tire within the current judgment period are within the preset tire pressure range for sandy roads.

[0067] If all the first front tire pressure values ​​and all the second front tire pressure values ​​are within the preset sand road front tire pressure range, and all the first rear tire pressure values ​​and all the second rear tire pressure values ​​are within the preset sand road rear tire pressure range, then the vehicle's current tire pressure status is determined to be the same as the preset sand road tire pressure status.

[0068] If at least one of the first and second front tire pressure values ​​is not within the preset front tire pressure range for sandy roads, and / or at least one of the first and second rear tire pressure values ​​is not within the preset rear tire pressure range for sandy roads, then the vehicle's current tire pressure is determined to be different from the preset tire pressure range for sandy roads. Both the front and rear tire pressure ranges for sandy roads can be set according to the tire pressure required for driving on sandy roads.

[0069] S202, search for a throttle opening greater than a preset opening among the throttle openings collected within the current judgment period.

[0070] In this embodiment, the preset opening is set according to the throttle required for driving on sandy roads. For example, the preset opening can be 40% or 45%.

[0071] S203, based on the number of throttle openings greater than a preset opening within the current judgment period, determine whether the current throttle state of the vehicle is the same as the preset sand road throttle state.

[0072] In this embodiment, the ratio of the number of throttle openings greater than a preset opening degree within the current judgment period to the total number of throttle openings collected within the current judgment period is calculated to obtain a weight value. If the weight value is greater than the preset value, it is determined that the current throttle state of the vehicle is the same as the preset sand road throttle state; if the weight value is less than or equal to the preset value, it is determined that the current throttle state of the vehicle is not the same as the preset sand road throttle state. The preset value can be set as needed, for example, the preset value can be set to 0.3, 0.25, etc.

[0073] For example, the preset value is 0.3. If the current judgment period is from 3:13 to 3:15, and the total number of throttle opening measurements collected within the current judgment period is 40, with 4 exceeding the preset opening, then 4 divided by 40 equals 0.1. Since 0.1 is less than the preset value, it is determined that the vehicle's current throttle state is different from the preset sand road throttle state, and monitoring continues. If the number of throttle opening measurements exceeding the preset opening is 35 within the current judgment period, then 35 divided by 40 equals 0.875. Since 0.875 is greater than 0.3, it is determined that the vehicle's current throttle state is the same as the preset sand road throttle state.

[0074] S204, when the current tire pressure of the vehicle is the same as the tire pressure of the sand road and the current throttle position of the vehicle is the same as the throttle position of the sand road, it is determined that the vehicle parameter indicates that the current vehicle state is the same as the preset vehicle state for sand roads.

[0075] In this embodiment, due to the high resistance of sandy roads, vehicles require a larger throttle when driving on sandy roads, resulting in a larger throttle opening. When driving on sandy roads, to increase the contact area between the tires and the sand and thus improve the vehicle's grip, the tire pressure is lower than that for normal road surfaces. Therefore, this application uses tire pressure and throttle opening to accurately determine whether the vehicle is in a sandy road condition.

[0076] In one possible implementation, the tire pressure values ​​include a first front tire pressure value, a second front tire pressure value, a first rear tire pressure value, and a second rear tire pressure value.

[0077] like Figure 5 As shown, the implementation process of step S201 may include:

[0078] S2011, calculate the average value of the first front tire pressure and the second front tire pressure at the same sampling time within the current judgment period to obtain the average front tire pressure.

[0079] S2012, calculate the average value of the first rear tire pressure and the second rear tire pressure at the same sampling time within the current judgment period to obtain the average rear tire pressure.

[0080] S2013, if the average front tire pressure is less than or equal to a first preset value and the average rear tire pressure is less than or equal to a second preset value, then the current tire pressure state of the vehicle is determined to be the same as the tire pressure state on the sandy road.

[0081] S2014, if any of the average front tire pressure values ​​is greater than the first preset value, and / or any of the average rear tire pressure values ​​is greater than the second preset value, then it is determined that the current tire pressure state of the vehicle is different from the tire pressure state on the sandy road.

[0082] In this embodiment, since the front tire pressure and rear tire pressure of a vehicle may be different when driving on sandy roads, it is necessary to determine whether the front tire pressure value meets the requirements for driving on sandy roads, and whether the rear tire pressure value meets the requirements for driving on sandy roads.

[0083] For example, the first preset value can be 1.2 Bar or 1.3 Bar, etc. The second preset value can be 1 Bar or 1.1 Bar, etc.

[0084] In this embodiment, the average front tire pressure and the average rear tire pressure can be used to more easily and quickly determine whether the vehicle's current tire pressure is the same as that of the sandy road.

[0085] In one possible implementation, step S202 may further include:

[0086] Calculate the average of the first front tire pressure and the second front tire pressure at the same sampling time within the current judgment period to obtain the average front tire pressure. Calculate the average of the first rear tire pressure and the second rear tire pressure at the same sampling time within the current judgment period to obtain the average rear tire pressure.

[0087] The difference between the average tire pressure before and after the test is calculated to obtain the first difference value. The difference between the average tire pressure after the test and the second preset value is calculated to obtain the second difference value. If the first difference value corresponding to the same sampling time is less than the first preset difference value and the second difference value is less than the second preset difference value, then it is determined that the current tire pressure state of the vehicle is the same as the tire pressure state on the sandy road.

[0088] For example, the first preset value can be 1 or 0.9, etc. The second preset value can be 0.8 or 0.7, etc. The first preset difference can be 0.2 or 0.3, etc. The second preset difference can be 0.2 or 0.3, etc.

[0089] In one possible implementation, when determining whether the current vehicle state is the same as the preset sand road vehicle state, it can also be determined based on the vehicle's throttle opening.

[0090] Specifically, when the vehicle parameters include throttle opening, if the current throttle state of the vehicle is the same as the preset throttle state for sandy roads, the vehicle parameters indicate that the current vehicle state is the same as the preset vehicle state for sandy roads.

[0091] Specifically, such as Figure 6 As shown, after step S101, the method for determining whether the current vehicle state is the same as the vehicle state on the sandy road includes:

[0092] S301, search for throttle openings that are greater than the preset openings among the throttle openings collected within the current judgment period.

[0093] S302, based on the number of throttle openings greater than a preset opening within the current judgment period, determine whether the current throttle state of the vehicle is the same as the throttle state of the sand road.

[0094] S303, when the vehicle's current throttle state is the same as the sand road throttle state, determine that the vehicle parameters indicate the current vehicle state is the same as a preset sand road vehicle state. In one possible implementation, when the vehicle parameters include throttle opening, the method for determining the target driving strategy includes:

[0095] Calculate the average throttle opening value collected within the current judgment period. Use the driving strategy corresponding to the preset throttle opening interval where the average throttle opening value falls as the target driving strategy.

[0096] In this embodiment, different preset opening ranges are pre-set, and each preset opening range corresponds to a driving strategy.

[0097] In one possible implementation, when vehicle parameters include tire pressure values, the method for determining the target driving strategy includes:

[0098] Calculate the average tire pressure value collected within the current judgment period; and use the driving strategy corresponding to the preset tire pressure range in which the tire pressure value is located as the target driving strategy.

[0099] In this embodiment, different preset tire pressure ranges are pre-set, and each preset tire pressure range corresponds to a driving strategy. When the tire pressure values ​​include the first front tire pressure value, the second front tire pressure value, the first rear tire pressure value, and the second rear tire pressure value, the average tire pressure is the average of the first front tire pressure value, the second front tire pressure value, the first rear tire pressure value, and the second rear tire pressure value.

[0100] In one possible implementation, when vehicle parameters include throttle opening, the method for determining the target driving strategy includes:

[0101] Calculate the average throttle opening value collected within the current judgment period; and take the driving strategy corresponding to the preset opening interval where the average opening value is located as the target driving strategy.

[0102] In this embodiment, different preset opening ranges are pre-set, and each preset opening range corresponds to a driving strategy.

[0103] In one possible implementation, when vehicle parameters include throttle opening and tire pressure, the method for determining the target driving strategy includes:

[0104] The system calculates the average throttle opening value collected within the current judgment period; it also calculates the average tire pressure value collected within the current judgment period; and based on the preset throttle opening interval and the preset tire pressure interval where the average throttle opening value lies, it determines the target driving strategy. In this embodiment, a pre-set correspondence between the preset throttle opening interval, the preset tire pressure interval, and the driving strategy is established. This pre-set correspondence can be presented in tabular form.

[0105] For example, Table 1 below shows the correspondence between preset opening range, preset tire pressure range, and driving strategy.

[0106] Table 1. Correspondence between tire opening range, tire pressure range, and driving strategy

[0107] Preset opening interval a Driving Strategy 1 Driving Strategy 4 Driving Strategy 7 Preset opening range b Driving Strategy 2 Driving Strategy 5 Driving Strategy 8 Preset opening range c Driving Strategy 3 Driving Strategy 6 Driving Strategy 9

[0108] In this embodiment of the application, since the throttle opening and tire pressure value of the vehicle may change in real time, the target driving strategy can be determined by using the throttle opening and / or tire pressure value, so that the target driving strategy changes with the change of the vehicle's state and makes the target driving strategy more in line with the current scenario in which the vehicle is located.

[0109] 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.

[0110] Corresponding to the method for determining whether a vehicle is in desert off-road condition as described in the above embodiments, Figure 7 The diagram shows a structural block diagram of a device for determining whether a vehicle is in a desert off-road state, as provided in an embodiment of this application. For ease of explanation, only the parts relevant to the embodiment of this application are shown.

[0111] Reference Figure 7 The device 400 may include a vehicle parameter acquisition module 410 and a status determination module 420.

[0112] The vehicle parameter acquisition module 410 is used to acquire the vehicle's location information and the vehicle's parameters, wherein the vehicle parameters include throttle opening and tire pressure value, or the vehicle parameters include the throttle opening.

[0113] The status determination module 420 is used to determine that the vehicle is in desert off-road state when the location information indicates that the vehicle is located in a desert area and the vehicle parameters indicate that the current vehicle state is the same as the preset sand road vehicle state.

[0114] In one possible implementation, the state determination module 420 also includes:

[0115] The display module is used to display the target driving strategy, wherein the target driving strategy is a preset driving strategy corresponding to the vehicle being in the desert off-road state;

[0116] Alternatively, a display module may be used to display the target driving strategy and the target vehicle maintenance strategy, wherein the target vehicle maintenance strategy is a preset vehicle maintenance strategy after the vehicle has been driven in the desert.

[0117] In one possible implementation, the vehicle parameters include throttle opening and tire pressure.

[0118] The status determination module 420 can be specifically used for:
