Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0052] It should be noted that the concepts such as "first" and "second" mentioned in the disclosure of the present invention are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0053] It should be noted that the modifications of "one" and "plurality" mentioned in the disclosure of the present invention are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0054] In order to better understand the technical names involved in the present invention, the following explanations are given.

[0055] Binary evaluation method: refers to the subjective evaluation results being divided into comfort and discomfort only.

[0056] See also Figure 1 , shows a flow chart of a method for determining the comfort level of a vehicle driving provided by an embodiment of the present invention, the method for determining the comfort level of a vehicle driving specifically comprises the following steps:

[0057] S101: Acquire operation information of a vehicle driven by a user, where the operation information at least includes a state value of each state item in a plurality of state items related to the vehicle operation state.

[0058] In the embodiment of the present application, a plurality of status items related to the vehicle are pre-set, wherein the status items related to the vehicle running state may be motion parameters generated during the vehicle driving process, such as acceleration, steering wheel angle, user expression information, environmental information, and the like.

[0059] In the specific process of executing step S101, a corresponding collection and storage device is set up on the vehicle, and the operation information of the user driving the vehicle can be collected in real time through the collection and storage device, and the collected operation information is stored.

[0060] It should be noted that the collected vehicle operation information at least includes a state value of each state item in a plurality of state items related to the current operation state of the vehicle.

[0061] S102: for each preset indicator item, determine at least one target state item corresponding to the indicator item from a plurality of state items, and determine the indicator value of the indicator item according to the state value of each target state item.

[0062] In the embodiment of the present application, multiple index items related to riding comfort can be preset, and the corresponding relationship between each index item and the state item can be set. Among them, one index item can correspond to one state item or multiple state items.

[0063] It should be noted that compared with directly collecting the indicator value of the indicator item, determining the indicator value of the indicator item based on the state value of at least one target state item related to the indicator item takes more comprehensive factors into consideration, and thus the determined indicator value will be more accurate.

[0064] For example, the pre-set multiple index items may be rapid acceleration, rapid deceleration, lateral acceleration, serpentine, lateral acceleration, longitudinal acceleration, etc. When the index item is lateral acceleration, the corresponding target state item may be speed, steering wheel angle. It may be set according to actual application, and the embodiment of the present application is not limited thereto.

[0065] In the specific process of executing step S102, after the operation information of the user driving the vehicle is collected by the collection and storage device installed on the vehicle, at least one target state item corresponding to each indicator item can be determined from multiple state items according to the correspondence between the preset indicator items and the state items; for each indicator item, according to the calculation method corresponding to the indicator item, the state values ​​of each target state item corresponding to the indicator item are calculated accordingly to obtain the indicator value of the indicator item.

[0066] For example, when the indicator item is lateral acceleration, according to the correspondence between the preset indicator item and the state item, the target state items corresponding to the indicator item (lateral acceleration) are determined to be speed and steering wheel angle respectively; the state value of the speed and the state value of the steering wheel angle are obtained from the acquired operation information, and according to the calculation method corresponding to the indicator item (lateral acceleration), the state value of the speed is squared and multiplied by the state value of the steering wheel angle and then multiplied by a constant coefficient, so as to obtain the indicator value of the indicator item, as shown in formula (1).

[0067] Z=aX 2 Y (1)

[0068] Among them, Z is the index value of the index item, X is the state value of the speed, Y is the state value of the steering wheel angle, and a is the constant coefficient.

[0069] S103: Determine the comfort level corresponding to each indicator item according to the indicator value of each indicator item and the preset indicator standard of each indicator item.

[0070] In an embodiment of the present application, for each indicator item, the initial indicator standard of each indicator item can be set in advance, and for the initial indicator standard of each indicator item, the following operations can be performed: the initial indicator standard of the indicator item is updated and optimized using the initial indicator standard of the indicator item and the historical operation information of the vehicle, and the updated optimization result of the initial indicator standard of the indicator item can be called the indicator standard of the indicator item.

[0071] Among them, the initial indicator standard of each indicator item includes an initial standard indicator interval and at least one initial non-standard indicator interval. The comfort level corresponding to the initial standard indicator interval is excellent. Each initial non-standard indicator interval corresponds to a comfort level. The comfort levels corresponding to different initial non-standard indicator intervals can be the same or different. The comfort level corresponding to the initial non-standard indicator interval is lower than the comfort level corresponding to the initial standard indicator interval. Correspondingly, the indicator standard of each indicator item also includes a standard indicator interval and at least one non-standard indicator interval. The comfort level corresponding to the standard indicator interval is excellent. Each non-standard indicator interval corresponds to a comfort level. The comfort levels corresponding to different non-standard indicator intervals can be the same or different. The comfort level corresponding to the non-standard indicator interval is lower than the comfort level corresponding to the standard indicator interval.

[0072] It should be noted that the initial standard indicator interval can be considered as an indicator value range, and each initial non-standard indicator interval can also be considered as an indicator value range. The initial standard indicator interval corresponds to the highest comfort level, and the closer the value of the initial non-standard indicator interval is to the initial standard indicator interval, the higher the comfort level. For example, the comfort level corresponding to the initial standard indicator interval in the initial indicator standard corresponding to the indicator item can be excellent, the comfort level corresponding to the first initial non-standard indicator interval is good, the comfort level corresponding to the second initial non-standard indicator interval is medium, and the comfort level corresponding to the third initial non-standard indicator interval is poor. Among them, the difference between the indicator value in the first initial non-standard indicator interval and the various indicator values ​​in the initial standard indicator interval is the smallest, and the difference between the various indicator values ​​in the third initial non-standard indicator interval and the various indicator values ​​in the initial standard indicator interval is the largest. In other words, the first initial non-standard indicator interval is closest to the initial standard indicator interval, and the third initial non-standard indicator interval is farthest from the initial standard indicator interval. Figure 2 shown.

[0073] It should also be noted that when the comfort level is excellent, it can be considered that the user's current driving feeling is comfortable; when the comfort level is good, it can be considered that the user's driving feeling is relatively uncomfortable; when the comfort level is medium, it can be considered that the user's driving feeling is uncomfortable; when the comfort level is poor, it can be considered that the user's driving feeling is extremely uncomfortable.

[0074] Furthermore, in the embodiment of the present application, multiple driving styles, multiple driving postures and multiple road traffic flow conditions are pre-set. For each driving style, driving posture and road traffic flow condition, the initial index standard corresponding to each index item under different driving styles, driving postures and road traffic flow conditions can be further set. For the same index item, the initial index standard corresponding to the index item is different under different driving styles, driving postures and road traffic flow conditions; accordingly, the embodiment of the present application can pre-set the initial index standard corresponding to the index item under different driving styles, driving postures and road traffic flow conditions for each index item, and then realize the adaptive adjustment of the initial index standard with the actual situation to obtain the corresponding index standard, so that the comfort determination result is more in line with the current actual driving scene.

[0075] As a preferred method of an embodiment of the present application, for each index item, the current driving style of the vehicle, the current posture information of the user and the road traffic flow condition information of the road on which the vehicle is currently traveling can be obtained; the initial index standard corresponding to the index item under the current driving style, current posture information and current road traffic flow condition information is determined, so as to determine the historical comfort level corresponding to the index item based on the historical index value of the index item and the determined initial index standard.

[0076] The initial indicator standard of the same indicator item is different under different driving styles, different posture information and different road traffic flow status information. The posture information includes the driving posture of the vehicle currently driven by the user, and the road traffic flow status includes the road traffic flow status of the road currently driven by the vehicle.

[0077] In an embodiment of the present application, for each indicator item, the process of determining the indicator standard of the indicator item is as follows: obtaining historical operation information of the vehicle, wherein the historical operation information includes a historical state value of each state item related to the vehicle, and historical user subjective evaluation information corresponding to each indicator item; for each indicator item, determining at least one target state item corresponding to the indicator item from each state item of the historical operation information according to a preset correspondence between the indicator item and the state item; calculating a historical indicator value corresponding to the indicator item according to the historical state value of each target state item of the indicator item, so as to determine a historical comfort level corresponding to the indicator item according to the historical indicator value of the indicator item and a preset initial indicator standard of the indicator item; if the historical comfort level corresponding to the indicator item is different from the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item, updating the initial indicator standard of the indicator item using the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item to obtain the indicator standard of the indicator item; if the historical comfort level corresponding to the indicator item is the same as the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item, determining the initial indicator standard of the indicator item as the indicator standard of the indicator item.

[0078] Specifically, based on the historical indicator value of the indicator item and the initial indicator standard, the process of determining the historical comfort level corresponding to the indicator item can be as follows: comparing the historical indicator value of the indicator item with the initial standard indicator interval in the corresponding initial indicator standard; if the historical indicator value of the indicator item satisfies the initial standard indicator interval in the corresponding initial indicator standard, determining that the comfort level corresponding to the indicator item is excellent; if the historical indicator value of the indicator item does not satisfy the initial standard indicator interval, determining the target initial non-standard indicator interval in which the historical indicator value of the indicator item is located, and determining the comfort level corresponding to the target initial non-standard indicator interval as the historical comfort level corresponding to the indicator item.

[0079] The historical comfort level of the indicator item is compared with the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item; if the historical comfort level corresponding to the indicator item is different from the comfort level indicated by the historical user subjective indicator information corresponding to the indicator item, the initial indicator standard of the indicator item is updated using the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item to obtain the indicator standard of the indicator item; if the historical comfort level corresponding to the indicator item is the same as the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item, the initial indicator standard of the indicator item is determined as the indicator standard of the indicator item.

[0080] It should be noted that the comfort level indicated by the historical user subjective evaluation information is actively recorded by the user in the software interaction interface.

[0081] It should also be noted that if the historical indicator value of the indicator item is within the corresponding initial standard indicator range, it can be said that the historical indicator value of the indicator item meets the initial standard indicator range; if the historical indicator value of the indicator item is not within the corresponding initial standard indicator range, it can be said that the historical indicator value of the indicator item does not meet the initial standard indicator range.

[0082] As a preferred method of an embodiment of the present application, if the historical comfort level corresponding to the indicator item is different from the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item, and the comfort level indicated by the historical subjective evaluation information corresponding to the indicator item is excellent, the historical indicator value corresponding to the indicator item is used to adjust each interval in the initial indicator standard to obtain the indicator standard of the indicator item, so that the obtained indicator standard of the indicator item is more accurate and closer to the user experience.

[0083] If the historical comfort level corresponding to the indicator item is different from the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item, and the comfort level indicated by the historical subjective evaluation information corresponding to the indicator item is not excellent, the intervals corresponding to the comfort level indicated by the historical subjective evaluation information corresponding to the indicator item are used to adjust each interval in the initial indicator standard of the indicator item to obtain the indicator standard of the indicator item.

[0084] For example, the intervals in the initial indicator standard corresponding to a certain indicator item are: initial standard indicator interval [10-19], first initial non-standard indicator interval [20-29], and second initial non-standard indicator interval [30-39].

[0085] If the historical comfort level corresponding to the indicator item is different from the comfort level indicated by the historical user subjective evaluation information corresponding to the indicator item, the comfort level indicated by the historical subjective evaluation information corresponding to the indicator item is excellent, and the historical indicator value of the indicator item is 20, the historical indicator value corresponding to the indicator item is used to adjust each interval in the initial indicator standard, and the indicator standard of the indicator item is: standard indicator interval [20-29], first non-standard indicator interval [30-39], second non-standard indicator interval [40-49].

[0086] As an implementation method, the interval corresponding to the comfort level indicated by the historical subjective evaluation information corresponding to the indicator item is used to adjust each interval in the initial indicator standard of the indicator item. The process of obtaining the indicator standard of the indicator item is specifically as follows: calculating the average value of each indicator value in the interval corresponding to the comfort level indicated by the historical subjective evaluation information corresponding to the indicator item, and using the average value to adjust each interval in the initial indicator standard to obtain the indicator standard of the indicator item, so as to make the obtained indicator standard of the indicator item more accurate.

[0087] For example, the intervals in the initial indicator standard corresponding to a certain indicator item are: initial standard indicator interval [10-19], first initial non-standard indicator interval [20-29], and second initial non-standard indicator interval [30-39].

[0088] If the historical comfort level corresponding to the indicator item is medium, and the comfort level indicated by the historical subjective evaluation information corresponding to the indicator item is poor, it can be calculated that the average value of each indicator value in the interval corresponding to the comfort level indicated by the historical subjective evaluation information corresponding to the indicator item is 34.5. The average value is used to adjust each interval in the initial indicator standard to obtain the indicator standard of the indicator item: standard indicator interval [10-29], first non-standard indicator interval [30-49], second non-standard indicator interval [50-69].

[0089] The above is merely a preferred method provided in an embodiment of the present application for adjusting the various intervals in the initial indicator standard of the indicator item. In actual application, the various intervals in the initial indicator standard of the indicator item can also be adjusted in other ways, which is not limited in the embodiment of the present application.

[0090] In the specific process of executing step S103, for each indicator item, after determining the indicator value of the indicator item according to the state values ​​of each target state item corresponding to the indicator item, the indicator standard corresponding to the indicator item is obtained, and then it can be judged whether the indicator value of the indicator item meets the standard indicator interval of the indicator standard of the indicator item set in advance. If the indicator value of the indicator item meets the standard indicator interval of the indicator standard of the indicator item, it is determined that the comfort level corresponding to the indicator item is excellent;

[0091] When the index value of an index item does not satisfy the standard index interval of the index standard of the index item, the target non-standard index interval of the index value of the index item is determined, and the comfort level corresponding to the target non-standard index interval is determined as the comfort level corresponding to the index item.

[0092] It should be noted that if the indicator value of the indicator item is within the standard indicator interval of the indicator standard of the indicator item, it can be said that the indicator value of the indicator item meets the standard indicator interval of the indicator standard; if the indicator value of the indicator item is not within the standard indicator interval of the indicator standard of the indicator item, it can be said that the indicator value of the indicator item does not meet the standard indicator interval of the indicator standard of the indicator item.

[0093] S104: Determine the current comfort level of the user driving the vehicle according to the comfort level corresponding to each indicator item.

[0094] In the specific process of executing step S104, after determining the comfort level corresponding to each indicator item, it can be determined whether the comfort levels corresponding to the various indicator items are the same. If the comfort levels corresponding to the various indicator items are the same, the comfort level corresponding to any indicator item is determined as the current comfort level of the user driving the vehicle; if there are indicator items with different comfort levels among the various indicator items, the indicator item with the lowest comfort level among the various indicator items is determined as the target indicator item, and the comfort level corresponding to the target indicator item is determined as the current comfort level of the user driving the vehicle.

[0095] The present invention provides a method for determining the comfort of driving a vehicle, which is pre-set with multiple index items, at least one state item corresponding to each evaluation index item, and an index standard. The operation information of the user driving the vehicle is obtained, and at least one target state item corresponding to each index item is determined from the operation information, so as to determine the index value corresponding to each index item according to the state value of each target state item corresponding to each index item; finally, according to the index value of each index item and the pre-set index standard of each index item, the comfort level corresponding to each index item is determined, and then according to the comfort level corresponding to each index item, the current comfort level of the user driving the vehicle can be determined. The technical solution provided by the present invention can realize the evaluation of the comfort level of the user driving the vehicle without manual intervention, which can not only improve the efficiency of the evaluation of the comfort of driving the vehicle, but also solve the problem of fuzzy evaluation standards due to the influence of subjective factors of the evaluator in the prior art.
