However, those skilled in the art will recognize that the embodiments of the application can be practiced without these specific details. In other instances, well-known structures and devices are not described in detail in order to avoid obscuring the embodiments of the application.

[0048] In an embodiment, referring to Figure 1 , the application exemplarily shows a vehicle-machine interaction mode switching method, which specifically includes the following steps:

[0049] In step S110, the vehicle driving speed and road information are acquired, and the road information includes the current road speed limit.

[0050] In step S120, the speed difference value is calculated according to the current road speed limit and the vehicle driving speed, and the speed threshold is calculated according to the current road speed limit and the preset speed difference threshold.

[0051] In step S130, the speed difference value is judged according to the speed threshold to confirm the driving state. If the speed difference value exceeds the speed threshold, it is confirmed as a dangerous driving state, and the duration of the dangerous driving state is recorded.

[0052] In step S140, the preset dangerous driving interaction mode is matched based on the duration to determine the target interaction mode matched with the duration, and the vehicle-machine is switched to the target interaction mode.

[0053] For step S110, firstly, the vehicle driving speed and road information need to be acquired, wherein the road information at least includes the current road speed limit, so as to combine the vehicle driving speed for calculation and judgment subsequently, and it needs to be understood that the road information can also include but is not limited to other parameters or information related to the current driving environment, such as weather, air quality, etc.

[0054] For step S120, according to the current road speed limit and the vehicle driving speed, the speed difference value is calculated, and it needs to be understood that the speed difference value reflects the difference between the current vehicle driving speed and the road speed limit where the vehicle is located, and the numerical form of the speed difference value includes positive and negative values, for example, in some embodiments, the current road speed limit is 80 km / h, the vehicle driving speed is 85 km / h, and the speed difference value is calculated as "vehicle driving speed-current road speed limit", which is 5 km / h, and for example, in another embodiment, the current road speed limit is 80 km / h, the vehicle driving speed is 75 km / h, and the speed difference value is calculated as "vehicle driving speed-current road speed limit", which is -5 km / h; according to the current road speed limit and the preset speed difference threshold, the speed difference threshold is calculated, wherein the speed difference threshold is a preset coefficient, which is used to determine the range of acceptable speed difference value, i.e. the speed difference threshold, for example, in some embodiments, the current road speed limit is 80 km / h, and the speed difference threshold is 0.1, and the speed difference threshold is calculated as "current road speed limit*speed difference threshold", which is 8 km / h, and for example, in another embodiment, the current road speed limit is 80 km / h, and the speed difference threshold is -0.1, and the speed difference threshold is calculated as "current road speed limit*speed difference threshold", which is -8 km / h.

[0055] It can be understood that the calculation method of the speed difference value and the speed difference threshold in the above steps is provided for example for easy understanding, and in actual implementation process, the calculation method can be adjusted according to actual calibration, error estimation demand and other variables.

[0056] For step S130, according to the calculated speed difference threshold, the speed difference value is judged, whether the speed difference value has exceeded the speed difference threshold, if the speed difference value exceeds the speed difference threshold, it means that the vehicle driving speed compared with the current road speed limit has a large speed difference, then the current driving state is confirmed as dangerous driving state, and the duration of dangerous driving state is recorded, and the recording duration includes the commonly used timing method, including but not limited to using timing device, using timing function in virtual device or module or adding time stamp to driving state in real time, etc.

[0057] For step S140, based on the duration, the preset dangerous driving interaction mode is matched to determine the target interaction mode matched with the duration, and the vehicle machine is controlled to switch to the target interaction mode. It is worth noting that the duration is the length of a period of time, and the matching here refers to taking the length of time represented by the duration as a matching item, and matching it with one or more preset dangerous driving interaction modes, and screening out the dangerous driving interaction mode corresponding to the time interval matched with the length of time from the dangerous driving interaction mode. The dangerous driving interaction mode refers to the vehicle machine interaction mode preset for the dangerous driving state, such as the interaction mode that requires voice interaction as the main interaction mode, so as to reduce the risk brought by the interaction operation when the driver is judged to be in the dangerous driving state.

[0058] In the embodiment, the step of calculating the speed difference threshold according to the current road speed limit and the preset speed difference ratio threshold specifically includes:

[0059] Step S210, according to the road information, the preset database is matched, the database stores at least one set of preset road information and the corresponding relationship of the speed difference ratio threshold, and the target speed difference ratio threshold corresponding to the road information is determined according to the corresponding relationship;

[0060] Step S220, multiplying the current road speed limit and the target speed difference ratio threshold to obtain the speed difference threshold.

[0061] For steps S210-S220, the differential speed ratio threshold is determined by matching in the preset database according to the road information, which can include but is not limited to weather conditions, traffic density, etc. in addition to the current road speed limit. It should be understood that the differential speed threshold is calculated according to the current road speed limit and the differential speed ratio threshold, so the differential speed threshold is essentially a proportion reflected by a numerical value. Even under the same road conditions, the distinction between safe driving and dangerous driving of the vehicle will be different due to the influence of multiple factors such as road speed limit, weather conditions, traffic density, etc., and the differential speed threshold ratio will also be different. For example, under the same road section and speed limit, the differential speed ratio threshold should be smaller when driving in the rain than when driving in the sun. For example, in some embodiments, the database includes a plurality of preset differential speed ratio thresholds and corresponding preset road information, including a first differential speed ratio threshold and a second differential speed ratio threshold, wherein the first differential speed ratio threshold is 0.2, and the corresponding first road information is sunny driving with a road speed limit of 80 km / h, and the second differential speed ratio threshold is 0.1, and the corresponding second road information is rainy driving with a road speed limit of 80 km / h. For example, in another embodiment, a third differential speed ratio threshold and a fourth differential speed ratio threshold are included, wherein the first differential speed ratio threshold is -0.1, the corresponding first road information is sunny driving with a road speed limit of 80 km / h, the second differential speed ratio threshold is -0.2, and the corresponding second road information is rainy driving with a road speed limit of 80 km / h. As described above, by presetting at least one set of correspondence between the preset road information and the differential speed ratio threshold in the database, the database can be matched according to the actual acquired road information, so as to determine the target differential speed ratio threshold that best matches the current road information, and then multiply the current road speed limit by the target differential speed ratio threshold to obtain the differential speed threshold that best matches the current road speed limit

[0062] In the present embodiment, the step of matching the preset dangerous driving interaction mode based on the duration further includes the following steps:

[0063] Obtain at least one set of correspondence between the dangerous driving interaction mode and the duration interval, match the duration with the duration interval to obtain the target interval where the duration is located;

[0064] Confirm the dangerous driving interaction mode corresponding to the target interval as the target interaction mode matched with the duration.

[0065] For the above steps, different dangerous driving interaction modes are applied based on the length of the duration of the dangerous driving state. The correspondence between the dangerous driving interaction mode and the duration interval can be set by the car manufacturer according to the design standard in the car machine, or it can be set by the user according to the driving habits. The specific setting method changes with the difference of actual demand, which is not limited here. Most basically, if the number of corresponding relationships obtained is only one set, the step of matching the duration with the duration interval can be regarded as the judgment of the duration. If the duration is determined to fall within the duration interval, it is matched, and the dangerous driving interaction mode corresponding to the duration interval is directly confirmed as the target interaction mode. If the number of corresponding relationships obtained is multiple, that is, different dangerous driving interaction modes are used to cope with the different lengths of the duration of the dangerous driving state. At this time, the duration is matched according to the duration interval in the multiple corresponding relationships. For example, in some embodiments, the dangerous driving state is sustained, and the duration has reached 5S. The preset dangerous driving interaction mode includes a first interaction mode and a second interaction mode. The duration interval corresponding to the first interaction mode is greater than 3S and less than or equal to 6S, and the duration interval corresponding to the second interaction mode is greater than 6S. According to the matching result, the first interaction mode is selected as the target interaction mode corresponding to the 5S duration. As described above, the duration is matched to select the target interaction mode. On the one hand, only when the duration of the dangerous driving state enters the duration interval, the corresponding target interaction mode can be matched, which is helpful to avoid the error of interaction mode switching caused by detection error. On the other hand, different interaction modes can be matched based on different durations, which is helpful to improve the adaptability to different dangerous driving states.

[0066] In the present embodiment, the dangerous driving interaction mode includes voice priority interaction, and the voice priority interaction includes:

[0067] Adjusting the wake-up free time of the voice interaction to a preset longest threshold;

[0068] Hiding the interaction function of the car machine interface and issuing a voice interaction guide, the voice interaction guide including at least one of voice guide information, text guide information and virtual image guide information.

[0069] For the above steps, it can be understood that the wake-up free time generally refers to the wake-up free time of the voice interaction function of the car machine. In order to save power and prevent false triggering of interaction, the voice interaction function of the car machine will enter a sleep or standby state when it is not used for a period of time, and needs to be awakened by issuing a voice information or operation action. In order to avoid frequent wake-up operations leading to increased driving risk, the wake-up free time is set to a maximum threshold to reduce the number of wake-up operations. The interaction function of the car machine interface refers to the interaction function realized by touching the car machine interface. After determining that it is a dangerous driving state, the interaction function of the car machine interface is closed to avoid the driver frequently operating the car machine and increasing the risk. The closing method includes hiding the interaction content of the car machine interface, and at the same time issuing a voice interaction guide to guide the driver to interact through voice. The voice interaction guide can include but is not limited to at least one of voice guide information, text guide information, and virtual image guide information. The voice guide information is, for example, an audio "please use voice to issue commands" issued by the car machine audio. The text guide information is, for example, the text "please use voice to issue commands" displayed on the car machine interface. The virtual image guide information is, for example, a dynamic human image or a virtual image displayed on the car machine interface to prompt the driver to use voice interaction. The dynamic human image is, for example, a virtual assistant image of a car manufacturer making a loudspeaker shout action, etc.

[0070] In the present embodiment, the step of judging the speed difference value according to the speed difference threshold to confirm the driving state further comprises:

[0071] If the speed difference value is less than or equal to the speed difference threshold, it is confirmed to be a safe driving state, and the current interaction mode of the car machine is judged;

[0072] If the current interaction mode is one of the preset dangerous driving interaction modes, the car machine is controlled to switch to the preset common interaction mode;

[0073] If the current interaction mode is the common interaction mode, the current interaction mode is maintained.

[0074] For the above steps, it needs to be understood that steps S110-S140 in this embodiment can be executed in real time, so the interaction mode can be constantly switched as the driving state changes. When the car-machine interaction mode switching method in this embodiment is executed at a certain moment, if the driving state is a safe driving state, it means that the dangerous driving interaction mode does not need to be applied. At this time, there are two possible car-machine interaction modes, one is the normal interaction mode in the safe driving state, and the other is the dangerous driving interaction mode switched to due to the appearance of the dangerous driving state for a period of time. If it is the former, the current interaction mode is maintained, and no measures need to be taken to respond to the dangerous driving state. If it is the latter, the car-machine needs to be controlled to switch to the normal interaction mode corresponding to the safe driving state. The description of the normal interaction mode here is only to distinguish it from the dangerous driving interaction mode, and its specific content is different according to the driving habit, car-machine factory setting or later setting, for example, in some embodiments, the normal interaction mode gives priority to car-machine interface operation, adjusts the voice wake-up time to the shortest, closes all voice interaction guides, and displays all interaction buttons and modules of the car-machine interface.

[0075] In this embodiment, the road information is obtained by the following steps:

[0076] Sending a road information acquisition request to the vehicle navigation device to obtain first feedback information of the vehicle navigation device;

[0077] Taking the first feedback information as the road information.

[0078] For the above steps, the vehicle navigation device generally obtains road map information from the cloud through the network, so that the current road map corresponding information can be obtained by directly sending a road information acquisition request to the vehicle navigation device, which is beneficial to improve the execution response speed of the method and reduce the execution cost.

[0079] In this embodiment, the vehicle driving speed is detected by the following steps:

[0080] Sending a speed acquisition request to the speed sensor to obtain second feedback information of the speed sensor;

[0081] Taking the second feedback information as the vehicle driving speed.

[0082] For the above steps, the speed sensor is a device arranged in the automobile power transmission system to detect the speed in real time. The second feedback information obtained by sending a speed acquisition request to the speed sensor is taken as the vehicle driving speed, which is beneficial to improve the execution response speed of the method and reduce the execution cost.

[0083] As described above, in the vehicle-machine interaction mode switching method provided by the application, the vehicle driving speed and road information including the current road speed limit are first acquired, the speed difference value is calculated according to the current road speed limit and the vehicle driving speed, the speed difference threshold value is calculated according to the current road speed limit and the preset speed difference ratio threshold value, the speed difference value is judged according to the speed difference threshold value, if the speed difference value exceeds the speed difference threshold value, it is confirmed that the dangerous driving state is dangerous, and the duration of the dangerous driving state is recorded, the target interaction mode is matched based on the duration, and the vehicle-machine is switched to the target interaction mode. The application solves the problem that the interaction switching logic in the prior art is single, which leads to the difficulty in reasonably judging the interaction mode under different vehicle speeds and different working conditions, and the unreasonable selection of the interaction mode, can adaptively adjust the switching trigger standard of the vehicle-machine interaction mode according to the vehicle speed and the speed limit, reasonably select the interaction mode under different vehicle speeds and different working conditions, effectively reduce the risk brought by the interaction operation in the driving process, and has the characteristics of ingenious idea, high controllability and strong adaptability.

[0084] In an embodiment, the application also specifically provides a vehicle-machine interaction mode switching device, which corresponds to the vehicle-machine interaction mode switching method in the above-mentioned embodiments. Figure 3 As shown in the structure schematic diagram of the vehicle-machine interaction mode switching device in an exemplary embodiment of the application, Figure 3 is the structure schematic diagram of the vehicle-machine interaction mode switching device in an exemplary embodiment of the application, which comprises an acquisition module 301, a calculation module 302, a state judgment module 303 and an interaction control module 304, and the details of each module are as follows:

[0085] The acquisition module 301 acquires the vehicle driving speed and road information, and the road information includes the current road speed limit.

[0086] The calculation module 302 calculates the speed difference value according to the current road speed limit and the vehicle driving speed, and calculates the speed difference threshold value according to the current road speed limit and the preset speed difference ratio threshold value.

[0087] The state judgment module 303 judges the speed difference value according to the speed difference threshold value to confirm the driving state, if the speed difference value exceeds the speed difference threshold value, it is confirmed that the dangerous driving state is dangerous, and the duration of the dangerous driving state is recorded.

[0088] The interaction control module 304 matches the preset dangerous driving interaction mode based on the duration to determine the target interaction mode matched with the duration, and controls the vehicle-machine to switch to the target interaction mode.

[0089] The application provides a vehicle-machine interaction mode switching device, which first acquires a vehicle driving speed and road information including a current road speed limit, calculates a speed difference value according to the current road speed limit and the vehicle driving speed, calculates a differential speed threshold value according to the current road speed limit and a preset differential speed threshold value, judges the speed difference value according to the differential speed threshold value, confirms a dangerous driving state if the speed difference value exceeds the differential speed threshold value, records a duration of the dangerous driving state, matches a target interaction mode based on the duration, and controls the vehicle-machine to switch to the target interaction mode. The application solves the problem of single interaction switching logic in the prior art, which leads to unreasonable judgment of the interaction mode under different vehicle speeds and different working conditions, and unreasonable selection of the interaction mode. The application can adaptively adjust the switching trigger standard of the vehicle-machine interaction mode according to the vehicle speed and the speed limit, reasonably select the interaction mode under different vehicle speeds and different working conditions, effectively reduce the risk caused by the interaction operation in the driving process, and has the characteristics of ingenious idea, high controllability and strong adaptability.
