Fig. 1 is a schematic view of an application scenario according to an embodiment of the present application. The application scenario may include a cloud processing system 101, a target vehicle 102, and other vehicles 103.

The cloud processing system 101 may receive information sent by the target vehicle 102 and the other vehicles 103 that establish communication connection with the cloud processing system, and perform analysis processing on the information to generate a processing result. The cloud processing system 101 is installed on a server capable of providing various services, or a server cluster formed by a plurality of servers, or may be installed in a cloud computing service center, which is not limited in this embodiment of the present application.

Similarly, other vehicles 103 may have adjustable suspension systems, as well, and embodiments of the present application are not limited in this regard.

Fig. 2 is a schematic flow chart of a control method of a vehicle suspension according to an embodiment of the present application. The control method of the vehicle suspension of fig. 2 may be performed by the cloud processing system 101 of fig. 1 or the target vehicle 102.

As shown in fig. 2, the control method of the vehicle suspension includes:

s201, the travel section and the environmental information of the target vehicle are acquired.

The environmental information includes at least one of an in-vehicle temperature, humidity, and air quality of the target vehicle.

Specifically, the travel section may be determined using a car navigation, which determines the travel section of the target vehicle according to the location of the target vehicle and the section division in the map. It should be noted that the driving road section may be a road section where the target vehicle is currently located, or may be a road section to be driven in; when the driving road section is the current road section, the subsequent steps can adapt to the current situation in judging the motion sickness state and adjusting the suspension, and provide timely service for passengers; when the driving road section is the road section to be driven into, the follow-up step can judge the carsickness state of the front road section in advance, and the suspension adjustment is carried out before the driving road section, so that the possibility of generating the carsickness feeling of passengers after the driving road section is reduced.

Environmental information is collected by in-vehicle sensors. The passenger feels that the carsickness is not only related to road conditions, but also related to the environment. And acquiring environment information, and providing a judgment basis for determining the current state of the target vehicle in the subsequent step.

S202, determining the current road section attribute of the driving road section according to the driving road section and a predetermined road section attribute table.

The road section attribute table comprises preset road sections and preset road section attributes corresponding to the preset road sections, wherein the preset road section attributes comprise road sections easy to sickness or road sections difficult to sickness.

Specifically, a preset road section consistent with the driving road section is searched in a road section attribute table, and the preset road section attribute corresponding to the preset road section is the current road section attribute. For example, as one example, the road segment attribute table includes that the first road segment is a road segment easy to motion sickness and the second road segment is a road segment difficult to motion sickness, and when the driving road segment is the first road segment, the current road segment attribute is determined to be the road segment easy to motion sickness.

S203, determining the current state of the target vehicle according to the current road section attribute and the environment information.

Specifically, the current state includes a car-sickness prone state or a car-sickness hard state.

Specifically, when determining the current state of the target vehicle according to the current road section attribute and the environmental information, if the current road section attribute is a road section which is not easy to be carsickness, and the environmental information indicates that at least one of the temperature, the humidity and the air quality in the vehicle is located in the user history comfort zone, the current state of the target vehicle can be determined to be the state which is not easy to be carsickness; if the current road section attribute is a road section which is not easy to be carsickness, but the environment information indicates that at least one of the temperature, the humidity and the air quality in the vehicle is not located in the user history comfort zone, the current state of the target vehicle can be determined to be the car sickness easy state.

If the current road section attribute is a road section easy to carsickness, but the environment information indicates that the temperature, the humidity and the air quality in the vehicle are all located in a user history comfort zone, the current state of the target vehicle can be determined to be a state difficult to carsickness; if the current road segment attribute is a car sickness prone road segment, but the environmental information indicates that at least one of the temperature, humidity and air quality in the car is not located in the user history comfort zone, the current state of the target vehicle can be determined to be the car sickness prone state.

It should be noted that the historical comfort zone may be obtained by analyzing the historical motion sickness condition of the user. For example, if the user does not feel sick when the temperature in the vehicle is 15 degrees, the humidity is 50% and the air quality is excellent, the user can determine that the user's history comfort zone is 15 degrees, the humidity is 50% and the air quality is excellent.

Therefore, the current state of the target vehicle is determined according to the current road section attribute and the environment information, whether the user is easy to motion sickness or not is judged by combining the actual condition of the road section and the environment in the vehicle, and the judgment accuracy of the current state is improved.

S204, determining a target state to which the suspension of the target vehicle is to be adjusted, and adjusting the suspension state of the suspension to the target state when the current state is the motion sickness prone state.

The target state is used to bring the current state towards a less prone to motion sickness state.

Specifically, the suspension of the target vehicle is adjusted to the target state so that the current state approaches the state of being less prone to motion sickness, and the effect of reducing motion sickness feeling of the occupant is achieved.

According to the technical scheme provided by the embodiment of the application, the current road section attribute of the driving road section is determined according to the driving road section and the predetermined road section attribute table by acquiring the driving road section and the environment information of the target vehicle, so that whether the driving road section is a car sickness prone road section is determined; according to the current road section attribute and the environment information, determining the current state of the target vehicle, combining the road section attribute and the environment information, and jointly judging whether the vehicle is in a vehicle-sickness prone state or not by the multi-source data, so that the accuracy of judging the vehicle-sickness state is improved; under the condition that the current state is the easy-to-carsickness state, determining the target state to which the suspension of the target vehicle is to be adjusted, and adjusting the suspension state of the suspension to the target state, wherein the target state is used for enabling the current state to approach to the difficult-to-carsickness state, so that the accurate adjustment of the suspension under the easy-to-carsickness state is realized, and the carsickness feeling of passengers is reduced.

In some embodiments, before determining the current road segment attribute of the driving road segment according to the driving road segment and the predetermined road segment attribute table, the method further comprises:

acquiring seat pressure data detected by a plurality of vehicles and geographic position information corresponding to each seat pressure data;

and inputting the seat pressure data and the geographic position information into a pre-trained motion sickness road section detection model to obtain a road section detection result, wherein the road section detection result is used for indicating the road section attribute of the road section corresponding to the geographic position information.

In particular, the seat pressure data may be collected by a pressure sensor, the content of which may include information of the magnitude of the seat pressure, the peak-to-peak value of the pressure fluctuation, the frequency of the pressure fluctuation, and the like. The seat pressure data can reflect the jolt of the road surface at the geographic location of the vehicle when the data is collected.

And inputting the seat pressure data and the geographic position information into a car-sickness road section detection model, wherein the model can analyze according to all seat pressure data corresponding to the geographic position information recorded by history, and the road section detection result is obtained. For the same road segment, the road segment attribute may change due to road wear, road construction, etc. The road segment detection result can be used for updating the road segment attribute table to ensure that the road segment attribute of the road segment accords with the actual road condition so that the current road segment attribute queried by the target vehicle driving on the road segment is latest.

It should be noted that the plurality of vehicles may include the target vehicle itself. When the traveling road section of the target vehicle does not exist in the road section attribute table, the road section and the corresponding road section attribute may be newly added in the road section attribute table according to the road section detection result.

According to the technical scheme provided by the embodiment of the application, the seat pressure data detected by a plurality of vehicles and the geographic position information corresponding to each seat pressure data are acquired, and the seat pressure data and the geographic position information are input into the pre-trained car sickness road section detection model to obtain the road section detection result, so that a basis is provided for the road section attribute table of S202.

In some embodiments, determining a target state to which a suspension of a target vehicle is to be adjusted includes:

acquiring occupant information in a target vehicle, wherein the occupant information includes at least one of the number, age, and seated position of the occupant;

the target state is determined based on occupant information in the target vehicle.

Specifically, the occupant information may be manually input by a user, or may be automatically determined by an in-vehicle camera, a seat pressure sensor, a face recognition system, or the like.

Even if the road segment attribute and the environmental information for determining the motion sickness prone state are the same, there may be different suspension adjustment demands depending on the number, age, or riding position of the occupants. And determining a target state according to the passenger information, so as to ensure that the suspension adjustment can meet the requirements of different passengers individually.

According to the technical scheme provided by the embodiment of the application, the target state is determined according to the passenger information in the target vehicle by acquiring the passenger information in the target vehicle, so that the requirements of different passenger conditions in the vehicle can be met individually through suspension adjustment.

In some embodiments, determining the target state from occupant information within the target vehicle includes at least one of:

under the condition that the number of passengers is smaller than the preset number, determining that the target state is that the damping value of the suspension is smaller than a first preset damping value; under the condition that the number of passengers is larger than the preset number, determining that the target state is that the damping value of the suspension is larger than a first preset damping value;

in the case where the age of the occupant includes less than the first preset age or greater than the second preset age, determining that the target state is such that the damping value of the suspension is less than the second preset damping value; under the condition that the ages of the passengers are between the first preset age and the second preset age, determining that the target state is that the damping value of the suspension is larger than the second preset damping value;

in the case where the seated position of the occupant is the rear seat of the target vehicle, determining that the target state is such that the damping value of the suspension is less than a third preset damping value; in the case where the seated position of the occupant is the front seat of the target vehicle, it is determined that the target state is such that the damping value of the suspension is greater than the third preset damping value.

Specifically, the specific numerical value of the damping value of the suspension is related to the structure and various parameters of the suspension, and for the same suspension system, the damping value is small, the damping effect is good, the corresponding anti-bump capability is good, and a more stable riding feeling can be provided under a bump road condition, but the operability is relatively poor; the damping value is big, and the shock attenuation effect reduces, but the operability is better.

The preset number may be set automatically according to the number of seats of the target vehicle, or may be set manually by the user. When the number of passengers is smaller than the preset number, riding comfort is important, so that the target state is determined that the damping value of the suspension is smaller than a first preset damping value; when the number of passengers is larger than the preset number, the number of people in the vehicle is large, the overall mass is large, the inertia is large, and the vehicle is required to make avoidance operation if emergency occurs, and better operability is required, so that the damping value of the suspension is determined to be larger than the first preset damping value in the target state. For example, as one example, the number of seats of the target vehicle is 5 persons, and the preset number thereof is set to 3 persons; when the number of the passengers is 4, the target state is determined that the damping value of the suspension is larger than the first preset damping value.

The first preset age and the second preset age may be built-in the system or may be manually set by the user. For the same easy-to-carsickness condition, the older and older occupants may have a stronger carsickness feeling, so the target condition is determined according to the age. For example, as one example, the first preset age is 12 years old and the second preset age is 50 years old; when a 6 year old passenger exists in the target vehicle, the target state is determined that the damping value of the suspension is smaller than a second preset damping value.

When the seating position of the occupant is distributed on the rear seat, it can be considered that the occupant needs a smoother riding feeling; when distributed on the front seats, the passengers can be considered to need better maneuverability of the target vehicle; the target state is determined according to the seated position of the occupant. It should be noted that, the rear seat and the front seat herein take the example that there are two rows of seats in the target vehicle, but it should be understood that, for three rows and more of vehicles, the positions may be divided into front, rear or front, middle, rear, etc. regions, and different regions correspond to the target states of different damping values; the method can also be combined with the number of the passengers, and the target state of the passengers can be comprehensively determined according to the riding positions and the number of different passengers.

The first preset damping value, the second preset damping value and the third preset damping value can take the same value or different values. For convenience of use, for a vehicle capable of adjusting a suspension state in a gear, a default damping value of the suspension in a certain gear may be directly invoked, for example, for a vehicle with a suspension state divided into a motion gear and a comfort gear, a damping value smaller than a first preset damping value means to directly invoke a damping value corresponding to the comfort gear, a damping value larger than the first preset damping value means to directly invoke a damping value corresponding to the motion gear, and a second preset damping value and a third preset damping value may be similarly obtained.

According to the technical scheme provided by the embodiment of the application, the target state is determined by comparing at least one of the relation between the number of the passengers and the preset number, the relation between the age of the passengers, the first preset age and the second preset age and the specific position of the passenger in the target vehicle, so that the requirements of different conditions of the passengers in the vehicle can be met individually through suspension adjustment.

In some embodiments, prior to determining the target state based on occupant information in the target vehicle, further comprising:

acquiring the road section length of a driving road section;

under the condition that the road section length of the driving road section is smaller than the preset length, determining the target state as the current suspension state;

and when the length of the traveling road section is greater than the preset length, a step of determining the target state according to the occupant information is entered.

Specifically, in an actual road, there may be a case where a target vehicle becomes a motion sickness-prone state in a traveling road section, and becomes a motion sickness-less state after traveling into a next road section; when the length of the running road section is short, the running time of the target vehicle on the running road section is short, the short-time easy-to-carsickness state may not influence the user, the requirement of adjusting the suspension is considered to be absent, the target state is determined to be the current suspension state, namely, the current suspension state is maintained without adjustment, and the suspension overheat caused by frequent adjustment of the suspension state is avoided.

The preset length may be a fixed value, for example 100 meters, 200 meters, 300 meters, etc.; and a preset time can be set, and the condition that the easy carsickness state does not influence a user is considered to be when the running time is smaller than the preset time, so that the preset length is calculated in real time according to the product of the running speed of the target vehicle and the preset time. For example, as one example, considering that the user is not affected during traveling of the carsickness prone section for 10 seconds, when the traveling speed of the target vehicle is 72 km per hour, that is, 20 meters per second, the preset length is calculated to be 200 meters.

According to the technical scheme provided by the embodiment of the application, the relation between the road section length of the driving road section and the preset length is compared, the target state is determined to be the current suspension state when not necessary, the target state is determined according to the passenger information when necessary, the suspension is prevented from being overheated due to frequent adjustment of the suspension state, and the service life of the suspension is prolonged.

In some embodiments, determining a target state to which a suspension of a target vehicle is to be adjusted includes:

acquiring the road section curvature of a driving road section;

under the condition that the curvature of the road section is larger than the preset curvature, determining a target state in a first preset period;

under the condition that the curvature of the road section is smaller than the preset curvature, determining a target state in a second preset period;

wherein the first preset period is smaller than the second preset period.

Specifically, in an actual road, the curvature of a road section is also affected, when the curvature of the road section is larger, the passenger is more likely to generate motion sickness, and the target state needs to be determined more frequently to carry out suspension adjustment, so that the influence of the curvature of the road section on the motion sickness of the passenger is reduced; when the curvature of the road segment is small, the frequency of determining the target state may be reduced. The preset period is small, and the corresponding determination of the target state is more frequent, so that the first preset period is smaller than the second preset period. For example, when the road segment curvature is greater than a preset curvature, determining a target state with a period of 60 seconds; and when the curvature of the road segment is smaller than the preset curvature, determining the target state by taking 180 seconds as a period.

According to the technical scheme provided by the embodiment of the application, the preset period for determining the target state is obtained by comparing the magnitude relation between the curvature of the road section and the preset curvature, so that the motion sickness feeling of passengers in an actual road is relieved more closely and practically.

In some embodiments, in the case where the travel section is determined by the navigation information, the step of adjusting the suspension state of the suspension to the target state is entered before the target vehicle starts.

Specifically, the user typically uses navigation information when using the vehicle. Wherein the navigation information may include destination and route information. The route information comprises a pre-divided road section and a corresponding attribute of the road section. For example, assuming that the road segments are divided according to mountain regions, urban roads, expressways, etc., the attribute of the mountain road segments may be set in advance to be an easy-to-carsickness attribute, the attribute of the urban road segments to be an easy-to-carsickness attribute, and the attribute of the expressway segments to be a difficult-to-carsickness attribute.

After the target vehicle acquires the navigation information, the traveling road section can be determined based on the navigation information, so that the suspension state of the suspension can be adjusted to the target state before the target vehicle starts according to the information at the moment. Specifically, after determining the driving road section, the target vehicle may acquire the environmental information at this time, determine the current road section attribute of the driving road section according to the driving road section and the predetermined road section attribute table, then determine in advance whether the state of the target vehicle when driving to the driving road section is a state of easy carsickness or a state of difficult carsickness according to the current road section attribute and the environmental information, and determine the target state to which the suspension of the target vehicle is to be adjusted when the state of easy carsickness is predicted, and adjust the suspension state of the suspension to the target state.

In this way, by adjusting the suspension state to the suspension state suitable for the route before the target vehicle starts, frequent adjustment of the suspension during running is avoided, and riding comfort and driving stability are improved.

Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein in detail.

The following are device embodiments of the present application, which may be used to perform method embodiments of the present application. For details not disclosed in the device embodiments of the present application, please refer to the method embodiments of the present application.
