Detailed Description

To further clarify the above and other features and advantages of the present application, a further description of the present application is provided below with reference to the appended drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not limiting, as to those skilled in the art.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the specific details need not be employed to practice the present application. In other instances, well-known steps or operations have not been described in detail in order to avoid obscuring the present application.

Currently, car seats typically adjust the state of the seat by means of physical boss keys. The physical boss key may be a physical key and may be located in a variety of positions. A physical key is arranged at the left side or the right side door plate or the rear row armrest control box of the auxiliary driving seat, and the auxiliary driving seat driving motor is controlled jointly through the physical key and a hard wire so as to achieve the effect of adjusting the state of the auxiliary driving seat. The other is that a physical button is arranged on the right rear door plate, a control signal is sent to the auxiliary driving seat control module by means of the door and window controller, and the auxiliary driving seat driving motor is controlled so as to achieve the effect of adjusting the state of the auxiliary driving seat.

However, the above-described physical boss key functions have the following problems:

1. the current market is controlled by physical keys and hard wire/controller area network (Controller Area Network, CAN) wires, which are all controlled by a single point of a controller, software decoupling is not realized, and the intelligent degree is not high.

2. In a vehicle without the function of the physical boss key, the user needs to open the mould and add the physical key, thus leading to difficult vehicle money change or upgrading.

In addition, the general vehicle-mounted function system design is not beneficial to development and change of functions according to user experience requirements, and in the changing process, a series of logic or data signals of related controllers are required to be changed, agile development is not supported, and subsequent function reconstruction and expansion cannot be realized, so that thousands of users can not experience thousands of people.

In view of this, in one aspect of the present application, the vehicle-mounted management system is constructed by adopting the SOA technology, that is, the functional software design architecture is decoupled, and split into two layers of services of a service layer and an application layer, and the basic functions of the vehicle (navigation, vehicle speed, vehicle state, seat adjustment, window adjustment, air conditioning adjustment, voice reminding, etc.) are converted into services of the service layer, and the service interface design is completed. And the application layer service (virtual boss key function, etc.) can call the service layer service, thus, the flexible layout design of the functional logic can be completed. Meanwhile, the function software in the controller or the controller can be decoupled, so that the function software does not depend on other function software any more, and the function software is not logically bound by using fixed data signal communication among the function software, but an Ethernet dynamic connection technology is applied to design a service interface, so that the function service can call basic service. Therefore, the problem that functions of the boss keys are not easy to change is solved, the boss keys can be restructured infinitely according to user requirements, only services used by the functions are required to be rearranged, and a service layer does not need to be changed or redesigned, so that the functions of the virtual boss keys are enabled to finish quick development of software, development cost is saved, and function expansibility is stronger. In addition, the required basic service can be called infinitely, the function recombination can be carried out, and the new virtual boss key function development and experience can be completed.

On the other hand, the virtual boss key service is controlled to be opened and closed on the vehicle-mounted display screen, so that the boss key function can be opened and closed without setting an entity physical key, the state adjustment of the vehicle-mounted seat is realized, and the riding comfort level of a user is improved. Therefore, when the boss key function is added, the vehicle model can be prevented from being improved, and the function upgrading cost is reduced.

and starting the virtual boss key function service based on the second screen setting information.

Here, the second screen setting information may be information generated by the second domain controller according to an opening operation of the user with respect to the switch interface of the virtual boss key function, and may be used to indicate that the virtual boss key function service is opened. The opening operation may be a click operation or a voice operation.

Specifically, the second domain controller may call a screen display service to display a switch interface of a virtual boss key function on a screen, and the user may set the switch interface through a click operation or a voice operation. The second domain controller may generate corresponding screen setting information for a setting operation of the switch interface by the user through a voice interaction service or a screen setting service. In the case where the setting operation is an opening operation, the corresponding screen setting information is second screen setting information for opening the virtual boss key function.

In the embodiment of the application, the second domain controller receives the opening operation of the user on the switch interface, and generates second screen setting information. The second domain controller sends second screen setting information to the first domain controller, and the first domain controller operates the virtual boss key function service after receiving the second screen setting information, so that the vehicle-mounted management system starts the virtual boss key function.

And after the second domain controller receives the first indication information, calling the voice interaction service to convert the first indication information into first voice information, and controlling the loudspeaker to play the first voice information.

To further rationally plan for vehicle use and to enhance ride comfort for rear passengers, in some embodiments, the occupancy information may include first-row occupancy status information and second-row occupancy status information, and the preset adjustment condition may include a first preset condition. In S23, before adjusting the state of the target seat by the seat adjusting service in the case where the occupancy information satisfies the preset adjustment condition, the seat adjusting method further includes:

determining the occupancy state of the other seats of the first row except the driving seat based on the first row occupancy state information;

determining a seating state of an opposing seat in a second row corresponding to other seats in the first row based on second row seating state information;

and determining that the occupied seat information meets the first preset condition under the condition that the occupied seat state of other seats is unoccupied and the occupied seat state of the opposite seat is occupied.

Here, the first-row seating state information may include seating states of the respective seats of the first row. The second row seating state information may include seating states of respective seats of the second row. The occupied state may include both occupied and unoccupied states. Occupancy may refer to the seating being taken by a person. Unoccupied means that the seat is unoccupied.

The other seats in the first row of seats than the driver seat may be one or two seats in the first row than the driver seat. The first row of seats may include two boundary seats. The driver seat of the first row belongs to a border seat. The other seats of the first row may include another border seat of the first row.

In the case where the number of seats in the first row is not greater than the number of seats in the second row, each seat in the first row has an opposing seat in the second row opposite thereto. The seats of the first row are on the same axis as the opposing seats of the second row, i.e., in a fore-aft relationship.

For example, if the driver seat of the first row is at the left boundary position of the first row, the opposing seat of the driver seat of the second row is the left boundary seat. If the driver seat of the first row is at the right boundary position of the first row, the opposite seat of the driver seat of the second row is a right boundary seat. Similarly, the relative seating of other seats in the first row than the driver seat in the second row may be determined.

In the case where the other seats of the first row include one boundary seat in the first row, the opposing seats of the second row corresponding to the other seats of the first row may include one boundary seat in the second row. In particular, if the other seats in the first row include right boundary seats, then the opposing seats in the second row may include right boundary seats in the second row. If the other seats in the first row include left border seats, then the opposing seats in the second row may include left border seats in the second row.

Where the other seats of the first row may also include intermediate seats, the opposing seats of the second row corresponding to the other seats of the first row may also include intermediate seats of the second row.

In embodiments of the present application, the first preset condition may include that the other seats of the first row are unoccupied and that the opposing seats of the second row are occupied. The first domain controller invokes the occupancy recognition service, acquires first-row occupancy state information and second-row occupancy state information, determines whether other seats of the first row are occupied from the first-row occupancy state information, and determines whether opposite seats with other seats are occupied from the second-row occupancy state information. The first domain controller determines that the occupancy information satisfies a first preset condition when it is determined that the other seats of the first row are unoccupied and the opposing seats are occupied.

When the occupied state of the other seats and the occupied state of the opposite seats are other conditions except that the other seats are not occupied, the first domain controller determines that the occupied information does not meet the first preset condition.

It should be noted that, in the embodiment of the present application, the first domain controller also needs to determine whether the opposite seat exists according to the seat distribution position. If so, the first domain controller judges that the occupancy information meets a first preset condition. If not, the first domain controller stops acquiring the occupied state of the opposing seat.

In the above embodiment, the occupancy state of the other seats in the first row and the occupancy state of the opposite seat in the second row are determined by the occupancy information, respectively, so that it can be accurately determined whether the occupancy information satisfies the first preset condition.

In some embodiments, S24, in a case where the occupancy information satisfies the preset adjustment condition, adjusting the state of the target seat through the seat adjustment service may include:

and adjusting the states of other seats through the seat adjusting service under the condition that the occupancy information meets the first preset condition.

Here, the other seats may be one or two seats in the first row of seats other than the driver seat. Adjusting the state of the other seats can be understood as adjusting the position and the backrest angle of the other seats. That is, when the state of the other seat is not in the preset state, the state of the other seat is adjusted from the initial state to the preset state. Wherein the seat position in the preset state is forward of the seat position in the initial state, and the backrest angle in the preset state is not greater than the backrest angle in the initial state.

It should be noted that the preset state may be stored in the first domain controller in advance, or may be determined according to the adjustment state selected by the user.

In the embodiment of the application, the first domain controller determines that the occupancy information meets a first preset condition, so that other seats in the first row can be used as target seats, and the state of the other seats is adjusted to a preset state through the seat adjusting service. Therefore, the user space of the second seat can be increased and the riding comfort of the user can be improved by automatically adjusting the states of other seats in the first row.

In one example, when the ride-on seat is the left border seat of the first row, the on-board user sits on the right border seat of the second row, and the co-ride seat is unoccupied. The first domain controller adjusts the state of the passenger seat, i.e., moves the position of the passenger seat forward and decreases the back angle of the passenger seat, with the virtual boss key function on. Thus, the user space of the right boundary seat of the second row is increased, and the riding comfort of the vehicle-mounted user of the rear row is improved.

In some embodiments, the occupancy information may include more than two rows of occupancy states. The second domain controller may determine the seating state of the third row or the seats after the third row from the seating information, and may determine whether each of the occupied seats has a seat located at a front row relative position according to the seat distribution position in the case where at least one seat is occupied. If so, it is determined whether the seat in the front row relative position is occupied. If the other seat is unoccupied, the state of the other seat is adjusted.

Further, if the seat on the rear-row relative position of the occupied seat is not occupied, the occupied seat may be regarded as the target seat, and the position of the occupied seat may be adjusted rearward to increase the user space relative to the seat.

In some riding scenarios, special users, such as important users or users with oversized sizes, are generally seated in the rear row in order to further enhance the riding experience of the special users. In some embodiments, the occupancy information includes non-first-row occupancy personnel information. The preset adjustment conditions include a second preset condition, S23, and in the case where the seat occupation information satisfies the preset adjustment conditions, adjust the state of the target seat through the seat adjustment service, the seat adjustment method may further include:

acquiring non-first-row seat occupying personnel information from a second domain controller;

and determining whether the seat occupying information meets a second preset condition according to the non-first seat occupying personnel information.

Here, the non-first row may be any row other than the first row. For example, the non-first row may be any of the second row, the third row, and the subsequent rows. The occupant information may include identity information and body type information of the occupant. The identity information may include an identity importance level.

In the embodiment of the application, the occupancy personnel information is obtained by calling the occupancy identification service by the second domain controller. Specifically, the first domain controller calls the seat occupancy recognition service to control the camera to collect the vehicle-mounted internal space image, and then the seat occupancy recognition service is used for recognizing the identity information and the body type information of the seat occupancy personnel on each occupied seat based on the image recognition technology, so that the non-first-row seat occupancy personnel information is obtained.

The second preset condition may be a preset condition related to the size and identity of the occupant. The second preset condition is at least one of the following: the body type of the non-first row seat occupying personnel exceeds the preset body type, the identity importance degree of the non-first row seat occupying personnel exceeds the preset degree, and the identity importance degree of the non-first row seat occupying personnel exceeds the identity importance degree of the non-first row previous row seat occupying personnel.

Alternatively, the preset body shape may include, but is not limited to, a body shape having an obesity degree of 15%. The body shape of the non-first seat occupant exceeds the preset body shape, and the obesity degree of the non-first seat occupant is understood to be more than 15%.

The preset body shape may also include the body shape of the occupant of the previous row that is not the first row. The body shape of the non-first row of seat occupancy personnel exceeds the preset body shape, and the body shape of the non-first row of seat occupancy personnel can be understood to exceed the body shape of the previous row of seat occupancy personnel.

Therefore, the body type of the occupied seat person is used as a preset condition for adjusting the seat, the vehicle-mounted space can be reasonably and fully used, the occupied seat person with the oversized body type can enjoy a proper user space, and the user experience is further improved.

In addition, the preset body forms can also comprise the body forms of special groups such as pregnant women and the like. Therefore, the special body type is used as the adjusting condition, and convenience can be provided for seat occupying personnel of the special body type.

In the embodiment of the present application, the identity importance degree of the seat occupying person may be preset in the vehicle-mounted management system, or may be obtained from the enterprise management system by the vehicle-mounted management system. The preset degree can be set by the vehicle-mounted user according to the requirement. The preset degree can be a fixed value, and can also be the identity importance degree of the seat occupying personnel of the previous row which is not the first row.

For example, if the preset level is the fourth level and the importance level of the identity of the non-first seat occupant is the fifth level, the importance level of the identity of the non-first seat occupant may be considered to exceed the preset level. Or if the identity importance degree of the seat occupying person of the non-first row is the fifth level and the identity importance degree of the seat occupying person of the previous row of the non-first row is the fourth level, the identity importance degree of the seat occupying person of the non-first row can be considered to exceed the preset degree.

Therefore, the identity importance degree of the occupied person is used as the preset condition for adjusting the seat, so that an important user can feel a more comfortable riding environment, and the riding experience of the important user is improved.

In this embodiment of the present application, the first domain controller may obtain identity information and body type information of a non-first-row seat occupying person from the seat occupying identifying service, and then perform at least one of the following steps: the identity importance degree of the non-first seat occupying personnel is compared with the preset degree, and the identity importance degree of the non-first seat occupying personnel is compared with the preset degree.
