[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0051] In related technologies, manual mode switching by the driver can easily lead to driving risks, making it impossible to ensure the driver's driving safety. In addition, inexperienced drivers cannot choose the correct driving mode according to road conditions, which affects their driving experience. The incidence of traffic accidents also increases accordingly, threatening the driver's life and property safety.

[0052] To overcome the above problems, the present application proposes a driving mode switching method, which aims to determine the current driving section of the vehicle and, based on the relationship between the predetermined driving section and the driving mode in the all-terrain mode,

[0053] The vehicle's current driving segment is determined, and based on the relationship between the predetermined driving segment and the non-standard driving modes in the all-terrain mode, a target non-standard driving mode corresponding to the vehicle's current driving segment is determined. The all-terrain mode includes multiple non-standard driving modes, with different non-standard driving modes corresponding to different driving segments. If the all-terrain system switch for switching the all-terrain mode is not triggered, the vehicle's current driving mode is switched to the target non-standard driving mode for the vehicle's current driving segment. By determining the target non-standard driving mode corresponding to the vehicle's current driving segment based on the relationship between the predetermined driving segment and the non-standard driving modes in the all-terrain mode, the system automatically switches between driving modes or all-terrain modes, facilitating the user's driving experience. Furthermore, by collecting and uploading vehicle driving data, the cloud platform summarizes user habits, helping inexperienced drivers select the correct mode, improving their driving experience and enhancing driving safety. Adopting the correct driving mode improves the vehicle's drivability and reduces damage to the vehicle.

[0054] The embodiment of the present invention provides a driving mode switching method, see Figure 1 , Figure 1 A flowchart of a driving mode switching method according to an embodiment of the present application is shown, and the method includes the following steps:

[0055] Step S101: Determine the current driving section of the vehicle.

[0056] In this embodiment, by locating the vehicle position, GPS can be used to obtain the specific location information of the vehicle, and the road section where the vehicle is located at this time is determined based on the specific location information, thereby obtaining information that the vehicle is located in a specific driving section. For example, if the identification information of the road section is Xinhua Road, it is determined that the vehicle is located in the section of Xinhua Road.

[0057] Step S102: Determine the target non-standard driving mode corresponding to the current driving section of the vehicle based on the relationship between the predetermined driving section and the non-standard driving mode in the all-terrain mode. The all-terrain mode includes multiple non-standard driving modes, and different driving sections correspond to different non-standard driving modes.

[0058] In this embodiment, after determining the specific driving section on which the vehicle is currently located, based on the relationship between the predetermined driving section and the non-standard driving mode in the all-terrain mode, the relationship between the determined driving section and the non-standard driving mode in the all-terrain mode can be pushed via a cloud platform, or data can be stored locally on the vehicle. By matching the current driving section with the pre-selected non-standard driving mode in the all-terrain mode, the target non-standard driving mode corresponding to the current driving section is determined. For example, if the vehicle is located on Xinhua Road, and the non-standard driving mode in the all-terrain mode corresponding to Xinhua Road is the economic mode, then the driving mode that the current vehicle should execute is determined to be the economic mode. The all-terrain mode includes the standard driving mode and the non-standard driving mode, and the non-standard driving mode includes the economic driving mode, the sports driving mode, the snow driving mode, the mud driving mode and the mountain road driving mode. The above different driving modes are executed for different road conditions, which can improve the vehicle's passing performance.

[0059] Step S103: When the all-terrain system switch for switching the all-terrain mode is not triggered, the current driving mode is switched to the target non-standard driving mode on the current driving section of the vehicle.

[0060] In this embodiment, the all-terrain system switch is used to switch driving modes. Pressing the switch once displays the current driving mode via the instrument panel or text message. The switch is then triggered to switch driving modes and activate and deactivate all-terrain mode. When the all-terrain system switch is not triggered, indicating that the all-terrain mode function is not enabled, if the vehicle is currently traveling on Xinhua Road, the vehicle's current driving mode is switched to economy mode, and a request signal for the all-terrain mode to economy mode is sent to each subsystem, including the ESP system, EPS system, engine, transmission, and four-wheel drive system. Upon receiving the request signal for the all-terrain mode to economy mode, each subsystem enters the corresponding mode according to the corresponding relationship in the all-terrain function strategy table shown in Table 1, and reports the subsystem status.

[0061]

[0062] Table 1: All-terrain functional strategy table

[0063] In this embodiment, the target non-standard driving mode corresponding to the vehicle's current driving section is determined by the relationship between the predetermined driving section and the non-standard driving mode in the all-terrain mode. This allows an inexperienced driver to determine the current driving mode based on the relationship between the predetermined driving section and the non-standard driving mode in the all-terrain mode, thereby avoiding driving safety issues and poor driving experience caused by inexperienced drivers being unclear about road conditions or unable to select a driving mode based on road conditions. In a feasible embodiment, the method further includes:

[0064] In the case where the all-terrain system switch for switching the all-terrain mode is triggered, the moment when the all-terrain system switch is triggered is determined as the first moment,

[0065] determining a moment when the target non-standard driving mode corresponding to the current driving section of the vehicle is obtained as a second moment;

[0066] comparing the time sequence of the first moment and the second moment;

[0067] If the first moment is later than the second moment, switching the current driving mode to the driving mode currently corresponding to the all-terrain system switch on the current driving section of the vehicle;

[0068] If the second moment is later than the first moment, the current driving mode is switched to the target non-standard driving mode on the current driving section of the vehicle.

[0069] In this embodiment, an experienced driver can select a driving mode based on his own judgment of the road conditions and switch between various modes under the all-terrain mode through the all-terrain system switch. When he turns on the driving mode switching system, the cloud platform will push the target non-standard driving mode corresponding to the vehicle's current driving section, that is, the vehicle's current driving section is Xinhua Road, and the corresponding target non-standard driving mode is the economic driving mode. When the driver feels that the current section needs to adopt the sports driving mode based on his own judgment, the all-terrain system switch is triggered to switch the current driving mode to the sports driving mode. The moment when the all-terrain system switch switches the current driving mode to sport driving mode is recorded as the first moment T1, and the moment when the cloud platform pushes the target non-standard driving mode corresponding to Xinhua Road as economy driving mode is recorded as the second moment T2. A judgment is made between T1 and T2. If T1 is later than T2, the current driving mode is switched to the sport driving mode corresponding to the all-terrain system switch on Xinhua Road. If T2 is later than T1, the current driving mode is switched to the economy driving mode corresponding to the target non-standard driving mode on Xinhua Road. Therefore, experienced drivers can automatically switch driving modes using the target non-standard driving mode pushed by the cloud platform when they want to take a break. Drivers can also actively switch driving modes based on their own judgment of road conditions. Furthermore, drivers can simultaneously switch driving modes automatically and actively, facilitating the driving process for experienced drivers, improving driving safety, and reducing the risks associated with manually switching modes while driving.

[0070] In a feasible implementation manner, a vehicle yaw rate value and a vehicle yaw rate response time of the vehicle on a current driving section are collected;

[0071] When the vehicle yaw rate value is greater than a vehicle yaw rate threshold, and the vehicle yaw rate response time is greater than a vehicle yaw rate response time threshold, determining that the dynamic mark of the current driving section is in an activated state, and uploading the current driving section and the dynamic mark to a cloud platform;

[0072] If the proportion of dynamic marks in the same driving section that are in an activated state is greater than a preset proportion value, the driving section is determined to be a dynamic section.

[0073] In this embodiment, while the vehicle is traveling, the dynamic road condition judgment module collects the vehicle yaw rate value and the vehicle yaw rate response time during the vehicle's driving process. That is, while the vehicle is traveling on Xinhua Road, the vehicle yaw rate value and the vehicle yaw rate response time are collected. After the collected vehicle yaw rate value is compared with a vehicle yaw rate value threshold, if the vehicle yaw rate value is greater than the vehicle yaw rate value threshold, the judgment is continued. The size of the vehicle yaw angular velocity response time value is numerically compared with the vehicle yaw angular velocity response time threshold. When the vehicle yaw angular velocity response time is greater than the vehicle yaw angular velocity response time threshold, a dynamic mark is output. This mark can be 1, and 1 indicates that the dynamic mark of the current driving section is in an activated state. The information that the dynamic mark of Xinhua Road is in an activated state is uploaded to the cloud platform. The cloud platform collects the dynamic marks of Xinhua Road uploaded by different vehicles. When the ratio of the number of records of the dynamic mark in the activated state (50) to the sum of the records of the dynamic mark in the activated state (50) and the records of the dynamic mark in the inactivated state (25) is greater than 50% of the threshold, Xinhua Road is determined to be a dynamic section.

[0074] In one feasible implementation, the non-standard driving mode includes a sport mode; and when an all-terrain system switch for switching the all-terrain mode is not triggered, switching the current driving mode to the target non-standard driving mode on the current driving section of the vehicle includes:

[0075] When the vehicle is currently traveling on a dynamic road section and the all-terrain system switch for switching the all-terrain mode is not triggered, switching the current driving mode to the sport mode on the vehicle's current driving section;

[0076] The method further includes: when the vehicle's current driving section is the dynamic section and the all-terrain system switch for switching the all-terrain mode is triggered, prompting the user to switch the current driving mode to the sports mode in the dynamic section.

[0077] In this embodiment, when Xinhua Road is a dynamic section, it indicates that Xinhua Road is a winding section. When the vehicle is currently traveling on Xinhua Road, if the all-terrain system switch is not triggered, it indicates that the vehicle is currently in the driving mode pushed by the cloud platform. In this section, the current driving mode is switched to Sport mode to ensure driving safety. If the all-terrain system switch is triggered, it means that the driver has previously switched the vehicle's driving mode using the all-terrain system switch. The driver may not be aware that Xinhua Road ahead is a sharp curve and may have proactively switched the driving mode using the all-terrain system switch based on their own judgment. Therefore, the user is prompted to switch the current driving mode to Sport mode to ensure driving safety. By determining whether the road is a dynamic section, the driver is alerted when the vehicle enters this area, thereby ensuring driving safety.

[0078] In a feasible implementation, determining whether the driving mode currently corresponding to the all-terrain system switch is a non-standard driving mode;

[0079] When the driving mode currently corresponding to the all-terrain system switch is a non-standard driving mode and the operation time of the driving mode currently corresponding to the all-terrain system switch is greater than a first preset time threshold, the current driving section and the driving mode currently corresponding to the all-terrain system switch are uploaded to the cloud platform, so that the cloud platform establishes a relationship between the driving section and the non-standard driving mode under the all-terrain mode by collecting data from different vehicles.

[0080] In this embodiment, if Figure 2 The non-standard driving mode upload flow chart shown first determines whether the driving mode corresponding to the vehicle's current active switching through the all-terrain system switch is a non-standard driving mode. If it is a non-standard driving mode, the next process judgment is continued to determine whether the timer is turned on. If the timer is turned on, the activation time judgment is continued. When the activation time is greater than the preset threshold of 5 minutes, the data is determined to be valid data, that is, the driver has driven in economic driving mode on Xinhua Road for 8 minutes. Then, Xinhua Road and the corresponding economic driving mode corresponding to the active switching through the all-terrain system switch will be uploaded to the cloud platform. Through the driving experience summary of experienced drivers who actively switch to the corresponding driving mode using the all-terrain system switch, inexperienced drivers can automatically switch driving modes through the cloud platform push, realizing the collection of driving data and sending the driving data for corresponding applications.

[0081] Based on the same inventive concept, this application proposes a relationship determination method, referring to Figure 3 , Figure 3 : is a flowchart of a relationship determination method according to an embodiment of the present invention, the method comprising the following steps:

[0082] Step 301: collecting the number of times different vehicles actively switch to a non-standard driving mode via the all-terrain switch on the same driving section;

[0083] In this embodiment, based on the same inventive concept, a single vehicle will upload the non-standard driving mode adopted on Xinhua Road as driving data, and the cloud platform will collect the driving data of the non-standard driving modes adopted by different vehicles on Xinhua Road, and perform corresponding analysis and judgment to count the number of times different driving modes are adopted.

[0084] Step 302: When the number of times the same non-standard driving mode is used exceeds a preset number, a correspondence is established between the non-standard driving mode currently corresponding to the all-terrain system switch and the driving section.

[0085] In this implementation, after the cloud platform counts the number of times different non-standard driving modes are used on Xinhua Road, if a specific non-standard driving mode is activated through the all-terrain system switch more than a preset threshold of five times, this information is pushed to all drivers. When a vehicle reaches that road section, the driver is pre-emptively switched to the non-standard driving mode recorded by the cloud platform. For example, if the economy driving mode activates the all-terrain system switch six times, other drivers will be pre-emptively switched to economy driving mode when they reach Xinhua Road. The same principle applies to other road sections. By collecting and analyzing user driving data, the cloud platform establishes a complete mapping between the non-standard driving mode currently associated with the all-terrain system switch and the road section in question, helping inexperienced drivers select the correct mode.

[0086] In a feasible embodiment, a driving section and a driving mode currently corresponding to the all-terrain system switch are received, uploaded by a single vehicle; wherein the driving section and the driving mode currently corresponding to the all-terrain system switch are uploaded by the vehicle when the driving mode currently corresponding to the all-terrain system switch is a non-standard driving mode and the operation time of the driving mode currently corresponding to the all-terrain system switch is greater than a first preset time threshold;

[0087] According to the driving sections uploaded by different vehicles and the driving modes currently corresponding to the all-terrain system switch, the number of times the all-terrain switch is actively switched to the non-standard driving mode in the same driving section is obtained by counting.

[0088] In this embodiment, based on the same inventive concept, it is determined whether the driving mode corresponding to the current active switching of the vehicle through the all-terrain system switch is a non-standard driving mode. If it is a non-standard driving mode, the next process judgment is continued to determine whether the timer is turned on. If the timer is turned on, the activation time judgment is continued. When the activation time is greater than the preset threshold of 5 minutes, the data is determined to be valid data, that is, the driver has driven in the economic driving mode on Xinhua Road for 8 minutes. Then, Xinhua Road and the corresponding economic driving mode corresponding to the active switching through the all-terrain system switch will be uploaded to the cloud platform. Through the driving experience summary of experienced drivers who actively switch to the corresponding driving mode using the all-terrain system switch, inexperienced drivers can automatically switch the driving mode through the cloud platform push, thereby realizing the collection of driving data and sending the driving data for corresponding applications.

[0089] Based on the same inventive concept, this application proposes a driving mode switching device, referring to Figure 4 , Figure 4 Schematic diagram of a driving mode switching device according to an embodiment of the present invention. Figure 4 As shown, the device includes:

[0090] The first determining module 401 is used to determine the current driving section of the vehicle;

[0091] A second determining module 402 is configured to determine a target non-standard driving mode corresponding to the vehicle's current driving section based on a predetermined relationship between the driving section and the non-standard driving mode in the all-terrain mode, wherein the all-terrain mode includes multiple non-standard driving modes, and different driving sections correspond to different non-standard driving modes;

[0092] The switching module 403 is configured to switch the current driving mode to the target non-standard driving mode in the current driving section of the vehicle when the all-terrain system switch for switching the all-terrain mode is not triggered.

[0093] The embodiment of the present application provides a driving mode switching system. Figure 5 , Figure 5 Schematic diagram of the driving mode switching system is shown. Figure 5 As shown, the system includes:

[0094] Based on the same inventive concept, an embodiment of the present application provides a vehicle, including a driving mode switching device system as proposed in the fourth aspect of the present invention, wherein the system includes:

[0095] an all-terrain system switch for switching the all-terrain mode;

[0096] A vehicle controller connected to the all-terrain system switch, the vehicle controller being configured to execute the driving mode switching method described in the first aspect of the present invention;

[0097] A cloud platform connected to the vehicle controller, the cloud platform is used to execute the relationship determination method described in the second aspect of the present invention.

[0098] In this embodiment, the driver presses the all-terrain system switch, and the current driving mode is displayed on the instrument panel or in text messages. The switch is triggered to switch the driving mode and turn the all-terrain mode on and off. The vehicle controller is used to execute the driving mode switching method described in the first aspect of the present invention, and the cloud platform is used to execute the relationship determination method described in the second aspect of the present invention. The vehicle also includes a dynamic road condition judgment module for collecting vehicle yaw rate values ​​and vehicle yaw rate response time during driving. Specifically, while the vehicle is driving on Xinhua Road, the vehicle yaw rate values ​​and vehicle yaw rate response time are collected. After comparing the collected vehicle yaw rate values ​​with a vehicle yaw rate threshold, the judgment continues if the vehicle yaw rate value exceeds the vehicle yaw rate threshold. The vehicle yaw rate response time value is numerically compared with the vehicle yaw rate response time threshold, and a dynamic flag is output when the vehicle yaw rate response time exceeds the vehicle yaw rate response time threshold. The subsystems include the ESP system, EPS system, engine, transmission, and four-wheel drive system. After each subsystem receives the request signal that the all-terrain mode is the economic driving mode, as shown in the all-terrain function strategy table in Table 1, the subsystem enters the corresponding mode and feedbacks the subsystem status.

[0099] In this embodiment, a vehicle's current driving segment is determined, and a target non-standard driving mode corresponding to the vehicle's current driving segment is determined based on a predetermined relationship between the driving segment and non-standard driving modes in the all-terrain mode. The all-terrain mode includes multiple non-standard driving modes, with different driving segments corresponding to different non-standard driving modes. If the all-terrain system switch for switching the all-terrain mode is not triggered, the vehicle's current driving mode is switched to the target non-standard driving mode for the vehicle's current driving segment. By determining the target non-standard driving mode corresponding to the vehicle's current driving segment based on the predetermined relationship between the driving segment and the non-standard driving modes in the all-terrain mode, automatic switching of the driving mode or all-terrain mode is achieved, facilitating the user's driving experience. Furthermore, by collecting and uploading vehicle driving data, the cloud platform summarizes user habits, helping inexperienced drivers select the correct mode, improving their driving experience and enhancing driving safety. Furthermore, employing the correct driving mode improves the vehicle's roadworthiness and reduces damage to the vehicle during driving.
