Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As described above, in the conventional scheme of determining the seating position in the user's vehicle, it is necessary to install at least a separate door switch sensor module and infrared sensing module in the vehicle to achieve the technical effect of determining the position in the user's vehicle, however, in the current standard configuration of the vehicle, only the keyless entry function is added thereto, the door switch sensor module and the infrared sensing module are not normally configured in the standard configuration, and a high-powered vehicle is required to be configured, which results in that the vehicle of the standard configuration cannot achieve the function of determining the seating area of the user.
To at least partially solve one or more of the above-mentioned problems and other potential problems, an embodiment of the present invention proposes a method for determining a user's sitting position, which can be applied to a UWB positioning system existing in a standard configuration automobile, and uses the UWB positioning system for expanding under the conventional effect of a keyless entry function of the automobile, and accurately positions a user carrying an intelligent terminal into an entry area (i.e., a position of the vehicle) before entering the automobile through a UWB positioning module configured in the automobile, and determines the user's sitting position through a seat change after the user enters the automobile, thereby realizing the technical effect of accurately determining the user's sitting position on the basis of not increasing the cost of new configuration resources for a standard configuration automobile having the UWB positioning module (i.e., having the keyless entry function).
Hereinafter, specific examples of the present scheme will be described in more detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for determining a seating position of a user according to an embodiment of the present invention, which is applied to a main control module of a vehicle, and the main control module of the embodiment is a center for commanding and controlling other modules in the vehicle, and may be a module integrating calculation, scheduling and control, which can communicate with other modules in the vehicle. As shown in fig. 1, the method for determining a seating position of a user according to the present embodiment may include the steps of:
Step S11: and establishing close-range communication connection with an intelligent terminal carried by a user, and starting a plurality of vehicle-mounted UWB positioning modules.
In this embodiment, when the user carries the intelligent terminal close to the vehicle, the main control module in the vehicle establishes close range communication connection with the intelligent terminal carried by the user. After the main control module and the intelligent terminal are in close-range communication connection, a plurality of vehicle-mounted UWB positioning modules configured by the vehicle are started, namely the UWB positioning function of the vehicle is started, so that the position outside the vehicle of a user carrying the intelligent terminal is determined. In an alternative of this embodiment, the short-range communication connection may be a bluetooth connection.
In this embodiment, the smart terminal carried by the user may be a smart phone with UWB positioning function carried by the user, or may be a smart device such as a vehicle remote key with UWB positioning function, a smart watch, etc., and a UWB positioning chip is built in the smart device, which may interact with a plurality of vehicle-mounted UWB positioning modules of the vehicle.
Step S12: and determining the out-of-vehicle area where the intelligent terminal is positioned according to the UWB signals sent by the UWB positioning modules in the intelligent terminals received by the plurality of vehicle-mounted UWB positioning modules.
In this embodiment, the vehicle is provided with a positioning system including a plurality of vehicle-mounted UWB positioning modules that are provided outside the vehicle and can be used for a keyless entry function of the vehicle. Among them, UWB (Ultra Wide band) is a carrier-free communication technology that transmits data using non-sinusoidal narrow pulses in the order of nanoseconds to picoseconds.
In this embodiment, a plurality of vehicle-mounted UWB positioning modules disposed on a vehicle are not only used for keyless entry function of the vehicle, but also interact with an intelligent terminal carried by a user near the periphery of the vehicle to determine an area outside the vehicle where the intelligent terminal is located: the method comprises the steps that a UWB positioning module in the intelligent terminal sends UWB signals to a plurality of vehicle-mounted UWB positioning modules, the plurality of vehicle-mounted UWB positioning modules in the positioning system process according to the received UWB signals, and a main control module determines an out-of-vehicle area where the intelligent terminal is located according to a processing result sent by the vehicle-mounted UWB positioning modules through a whole vehicle bus system.
Step S13: when the intelligent terminal is in close-range communication connection with the intelligent terminal and the intensity of the UWB signal received by any vehicle-mounted UWB positioning module is lower than the preset intensity, determining that a user carrying the intelligent terminal enters the vehicle, and determining an external area of the vehicle where the intelligent terminal is located before entering the vehicle as an entering area.
In this embodiment, when the vehicle-mounted UWB positioning module receives the UWB signal sent by the intelligent terminal through the UWB positioning module, the vehicle-mounted UWB positioning module further determines the signal intensity of the received UWB signal, when any vehicle-mounted UWB positioning module in the positioning system determines that the intensity of the received UWB signal is lower than the preset intensity, the vehicle-mounted UWB positioning module sends the information that the current UWB signal intensity is lower than the preset intensity to the main control module, after the main control module receives the information, the main control module determines whether the main control module is in close-range communication connection with the intelligent terminal, and when the main control module determines that the main control module is in close-range communication with the intelligent terminal, a user currently carrying the intelligent terminal enters the vehicle.
When a user enters the vehicle, the plurality of vehicle-mounted UWB positioning modules arranged outside the vehicle can cause serious attenuation (namely, UWB signals are lower than preset intensity) due to the blocking of metal plates of the vehicle body, and the positioning system cannot accurately position the position of the intelligent terminal carried by the user in the vehicle. However, the user is far away from the vehicle, so that the intensity of UWB signals received by a plurality of vehicle-mounted UWB positioning modules outside the vehicle is lower than the preset intensity, and the near-field communication connection between the intelligent terminal carried by the user and the main control module is disconnected under the condition that the user is far away from the vehicle. Therefore, in this embodiment, when the positioning system can determine that the accurate position of the intelligent terminal according to the received UWB signal (i.e., the UWB signal is higher than the preset intensity) becomes that the positioning system cannot determine that the accurate position of the intelligent terminal according to the received UWB signal (i.e., the UWB signal is lower than the preset intensity), and the main control module is in close-range communication connection with the intelligent terminal, the main control module determines that the user carrying the intelligent terminal enters the vehicle, and determines the external area of the vehicle where the intelligent terminal is located before the intelligent terminal enters the vehicle as the entering area. It should be noted that, in this embodiment, the preset strength is a critical value that the position cannot be accurately determined according to the UWB signal, if the preset strength is higher than the critical value, the position can be accurately determined, if the preset strength is lower than the critical value, the position cannot be accurately determined, and in this embodiment, the specific numerical value of the preset strength is not limited.
Step S14: and acquiring a seat weight signal acquired by a seat sensor system to determine the bearing change information of the seat.
In this embodiment, the vehicle is further provided with a seat sensor system, the seat sensor system is used for collecting a seat weight signal corresponding to a seat, when a user enters the vehicle and sits on the seat in the vehicle, the seat sensor system can collect the seat weight signal corresponding to the seat and send the seat weight signal corresponding to the seat collected by the seat sensor system to the main control module, and the main control module determines the load-bearing change information of the seat according to the obtained seat weight signal.
Step S15: and determining the seat on which the user carrying the intelligent terminal sits according to the entering area and the bearing change information of the seat.
In this embodiment, the main control module may perform comprehensive judgment according to the determined load-bearing change information of the seat in the vehicle and the access area before the user enters the vehicle, so as to determine the seat in the vehicle where the user carrying the intelligent terminal takes, that is, the main control module determines the taking position of the user in the vehicle according to the load-bearing change information of the seat in the vehicle and the access area before the user enters the vehicle.
In this embodiment, the UWB positioning module configured in the vehicle is used to accurately position the user carrying the intelligent terminal in the entrance area before entering the vehicle, and the seat sensor system is used to determine the seat change after the user enters the vehicle, so as to determine the sitting position of the user, thereby realizing the technical effect of accurately determining the sitting position of the user on the basis of not increasing the cost of new configuration resources for the standard configuration vehicle with the UWB positioning module (i.e. having a keyless entrance function).
In combination with the above embodiment, in an implementation manner, the embodiment of the invention further provides a method for determining a sitting position of a user. Specifically, in the method, step S12 includes steps S21 to S23:
step S21: and receiving distances between the intelligent terminal and the plurality of vehicle-mounted UWB positioning modules, which are determined by the plurality of vehicle-mounted UWB positioning modules according to UWB signals sent by the UWB positioning modules in the intelligent terminal.
In this embodiment, the plurality of vehicle-mounted UWB positioning modules in the positioning system respectively determine distances between the intelligent terminal and the plurality of vehicle-mounted UWB positioning modules according to UWB signals sent by the UWB positioning modules in the intelligent terminal carried by the user. After the distances between the intelligent terminal and the plurality of vehicle-mounted UWB positioning modules are determined by the plurality of vehicle-mounted UWB positioning modules in the positioning system, the distances between the intelligent terminal and the plurality of vehicle-mounted UWB positioning modules are determined by the positioning system and are sent to the main control module through the whole vehicle bus system, and the main control module receives the distances between the intelligent terminal and the plurality of vehicle-mounted UWB positioning modules determined by the positioning system.
Step S22: and determining the position outside the vehicle where the intelligent terminal is located according to the distances between the intelligent terminal and the plurality of vehicle-mounted UWB positioning modules.
In this embodiment, the main control module may determine, according to the distances between the received intelligent terminal and the plurality of vehicle-mounted UWB positioning modules, position information of the intelligent terminal, that is, determine an off-vehicle position where the intelligent terminal is located. In an alternative embodiment, a plane graph coordinate system may be established with the vehicle as the center, position coordinates (X 1,Y1)、(X2,Y2)、(X3,Y3) of a plurality of vehicle-mounted UWB positioning modules and the like are determined in advance, and distances L 1、L2 between the plurality of vehicle-mounted UWB positioning modules and the intelligent terminal and the like are measured according to the plurality of vehicle-mounted UWB positioning modules, wherein the master control module may obtain the current position coordinates (X, Y) of the intelligent terminal according to formula 1:
l 1 2＝(X1-X)2+(Y1-Y)2 equation 1
The following describes in detail the method for determining the position coordinates (X, Y) of the current intelligent terminal, taking the vehicle mounted with 4 on-board UWB positioning modules as an example: the 4 vehicle-mounted UWB positioning modules are respectively: UWB 1、UWB2、UWB3、UWB4, it can be respectively located the outside left front, left back, right front, right back four positions of vehicle, UWB 1、UWB2、UWB3、UWB4 carries out UWB range finding with intelligent terminal respectively, obtains the distance between intelligent terminal and 4 on-vehicle UWB positioning module: and L 1、L2、L3、L4, then the main control module can obtain the position coordinates (X, Y) of the 4 intelligent terminals through triangular positioning (namely, the position coordinates are obtained through the same principle of a formula 1：L1 2＝(X1-X)2+(Y1-Y)2,L2、L2、L4), and average the position coordinates (X, Y) of the 4 intelligent terminals to obtain the out-of-vehicle positions (X, Y) of the intelligent terminals.
Step S23: and determining the outside area of the intelligent terminal according to the coverage areas of the preset areas and the outside position of the intelligent terminal, wherein the preset areas correspond to the doors one by one.
In this embodiment, a plurality of preset areas outside the vehicle are set in advance, each preset area corresponds to each door of the vehicle one by one, and a general vehicle (i.e., a vehicle having 4 doors) is taken as an example below, as shown in fig. 2, and fig. 2 is a schematic view of an outside area in one embodiment of the present invention. In fig. 2, the preset area a is an exterior area corresponding to the exterior of the main driving door, the preset area B is an exterior area corresponding to the exterior of the co-driving door, the preset area C is an exterior area corresponding to the exterior of the left rear door, and the preset area D is an exterior area corresponding to the exterior of the right rear door.
In this embodiment, each preset area is a designated area extending outwards from the corresponding door, and the specific distance extending outwards can be determined empirically by a skilled person, which is not limited in this embodiment. In this embodiment, a corresponding set of position coordinates may be set for each preset area, if the set of position coordinates of the preset area a is set a, the set of position coordinates of the preset area B is set B, and so on, after the main control module determines that the current external position of the intelligent terminal is located, it may determine, according to coverage areas of a plurality of preset areas, which set the external position (X, Y) of the intelligent terminal belongs to, if the external position (X, Y) belongs to set a, it is determined that the external area where the intelligent terminal is located is an area a, that is, an area corresponding to the main driving door, and if the external position (X, Y) belongs to set D, it is determined that the external area where the intelligent terminal is located is an area D, that is, an area corresponding to the right rear door of the vehicle.
In this embodiment, the main control module may determine, according to the distance information of the intelligent terminal returned by the positioning system, the current accurate position information of the intelligent terminal, and determine, according to the position information, an area outside the vehicle where the user currently carrying the intelligent terminal is located, and further determine which position outside the vehicle the user subsequently enters into, so as to provide a basis and a basis for subsequently determining a sitting position of the user in the vehicle, thereby implementing a determination that the user enters into the vehicle position without a door switch sensor, and saving vehicle configuration resources.
In combination with the above embodiment, in an implementation manner, the embodiment of the invention further provides a method for determining a sitting position of a user. Specifically, in the method, the seat sensor system includes a plurality of seat sensors, one for each seat, and in the method, step S31 is included in addition to steps S11 to S15, wherein step S14 includes steps S32 to S34:
step S31: and determining the starting time when the intensity of the UWB signal received by any vehicle-mounted UWB positioning module is lower than the preset intensity as a first time.
In this embodiment, when the main control module receives the information that the current UWB signal strength returned by the positioning system is lower than the preset strength, and the main control module is in close-range communication connection with the intelligent terminal, the main control module determines that the user currently carrying the intelligent terminal enters the vehicle and is in close-range communication connection with the intelligent terminal, and the starting time when the strength of the UWB signal received by any vehicle-mounted UWB positioning module is lower than the preset strength is determined as the first time, that is, the first time is recorded as the time when the user carrying the intelligent terminal enters the vehicle from outside the vehicle (for example, the first time is recorded as t 0).
Step S32: and acquiring a seat weight signal sensed by each seat sensor in a preset time period after the first moment, analyzing the seat weight signal, and determining the seat weight corresponding to the seat weight signal.
In this embodiment, each seat sensor in the vehicle collects a seat weight signal in a preset time period after a first time, where the preset time period is a preset time period for collecting the weight signal, that is, t 1, and the time period cannot be too long, if the preset time period can be 3s or 5s, each seat sensor in the vehicle collects a seat weight signal of a user entering the vehicle for 3s, and sends the seat weight signal sensed by each seat sensor to the main control module, and after the main control module obtains the seat weight signal collected by each seat sensor in the preset time period after the first time, the main control module analyzes the seat weight signal to obtain a seat weight value corresponding to the seat weight signal, so as to determine the seat weight corresponding to the seat weight signal. The preset time period in this embodiment is a time period determined according to manual experience, and specific values of the preset time period are not limited in any way.
Step S33: when the seat weight sensed by one seat sensor is greater than or equal to a first threshold value, the load bearing change information of the seat corresponding to the seat sensor is determined as follows: the sitting mode is changed from unmanned sitting to manned sitting.
In this embodiment, when the main control module determines that the seat weight sensed by one seat sensor is greater than or equal to the first threshold according to the analyzed seat weights, the load-bearing change information of the seat corresponding to the seat sensor is determined as follows: the sitting mode is changed from unmanned sitting to manned sitting. The first threshold in this embodiment is a critical weight value for determining whether a person sits on the seat, for example, the first threshold may be 30kg, for example, the weight of the seat in a preset time period after the first moment obtained by analysis by the main control module is greater than or equal to 30kg, and then the main control module determines that the load-bearing change information of the seat is: the sitting mode is changed from unmanned sitting to manned sitting.
Step S34: when the seat weight sensed by one seat sensor is smaller than a first threshold value, the bearing change information of the seat corresponding to the seat sensor is determined as follows: the sitting of the person is temporarily not needed or changed from the sitting of the person to the sitting of the person.
In this embodiment, when the main control module determines, according to the analyzed weights of the seats, that the weight of the seat sensed by one seat sensor is less than the first threshold, the load-bearing change information of the seat corresponding to the seat sensor is determined as follows: the sitting of the person is temporarily not carried out or changed from the sitting of the person to the sitting of the person. For example, the first threshold may be 30kg, if the weight of the seat in the preset time period after the first moment obtained by the analysis of the main control module is less than 30kg, the main control module determines that the load-bearing change information of the seat is: the sitting of the person is temporarily not needed or changed from the sitting of the person to the sitting of the person. It will be appreciated that when the seat weight is less than the first threshold, there may be either a temporary absence of a person sitting for a preset period of time or a person sitting down for a preset period of time, from a person sitting to an absence. In this embodiment, the first threshold may be set according to manual experience, and the specific value of the first threshold is not limited in this embodiment.
In this embodiment, the main control module accurately determines the load bearing change condition of each seat in the vehicle by using the seat weight signal sent by the seat sensor, so as to determine the riding position of the user by combining the load bearing change information of each seat in the vehicle and the vehicle exterior region before the user enters the vehicle, thereby providing a basis for accurately determining the riding position of the user.
In combination with the above embodiment, in an implementation manner, the embodiment of the invention further provides a method for determining a sitting position of a user. Specifically, in the method, step S15 includes steps S41 to S43:
step S41: when the access area is a front-row area and the front-row seat is changed from unmanned seat to occupied seat, the changed front-row seat is determined to be the seat on which the user carrying the intelligent terminal sits.
In this embodiment, the plurality of preset areas are divided into a front row area and a rear row area, and the plurality of seats in the vehicle are divided into a front row seat and a rear row seat. It can be understood that the front row region is a preset region corresponding to a front row door of the vehicle, the rear row region is a preset region corresponding to a rear row door of the vehicle, the front row seats are main driving and co-driving seats, and the rear row seats are seats of the rear row of the vehicle.
When the main control module determines that the entering area before a user carrying the intelligent terminal enters the vehicle is a front-row area and the seat sensor system judges that the bearing change information of the front-row seat is changed from unmanned sitting to occupied sitting, the main control module determines that the changed front-row seat is the seat on which the user carrying the intelligent terminal sits.
For example, when the main control module determines that the user carrying the intelligent terminal arrives at the area a, the user enters the vehicle from outside the vehicle to inside the vehicle through the area a, namely the entering area is the area a. In t 1 seconds after the user enters the car, if the main control module determines that the main driving seat is changed and is changed from being occupied to being occupied, the main control module judges that the user is occupied in the main driving seat until the user leaves the car, namely, the seat sensor system determines that the bearing change information of the main driving seat is changed from being occupied to being occupied, and the positioning system can accurately determine the accurate position of the user carrying the intelligent terminal again. It can be understood that the judgment of the co-driving position of the front seat is the same as the main driving judgment, namely, when the main control module determines that the user carrying the intelligent terminal arrives at the area B and enters the vehicle from the outside of the vehicle to the inside of the vehicle from the area B, namely, the entering area is the area B. And in t 1 seconds after the user enters the vehicle, if the main control module determines that the co-driver seat is changed and is changed from unmanned sitting to manned sitting, the main control module judges that the user sits on the co-driver seat.
In this embodiment, the riding positions of a plurality of users in the vehicle can be determined when a plurality of users ride on the vehicle. If two users respectively carrying intelligent terminals enter the vehicle through A, B areas respectively, the main control terminal can determine that the entering area of the user 1 is an area A, the entering area of the user 2 is an area B, and then the seat sensor system determines that the main driving seat and the auxiliary driving seat are changed from unmanned seats to occupied seats respectively, so that the main driving seat of the user 1 is determined, and the auxiliary driving seat of the user 2 is determined.
Step S42: when the entering area is a back row area and one of the back row seats is changed from unmanned sitting to occupied sitting, the changed back row seat is determined to be the seat on which the user carrying the intelligent terminal sits.
In this embodiment, when the main control module determines that the entering area before the user carrying the intelligent terminal enters the vehicle is a rear-row area, and the seat sensor system determines that the load-bearing change information of the rear-row seat is that the rear-row seat is changed from an unmanned seat to a manned seat, the main control module determines that the changed rear-row seat is the seat on which the user carrying the intelligent terminal sits.
For example, when the main control module determines that the user carrying the intelligent terminal arrives at the region C, the user enters the vehicle from outside the vehicle to inside the vehicle through the region C, i.e. the entering region is the region C. And in t 1 seconds after the user enters the vehicle, if the main control module determines that the back row is changed from sitting without a person to sitting with a person, the main control module judges that the user enters through the back row left side vehicle door and sits on the back row left seat. For another example, when the main control module determines that the user carrying the intelligent terminal arrives at the D area, the user enters the vehicle from outside the vehicle to inside the vehicle through the D area, i.e. the entering area is the D area. And in t1 seconds after the user enters the vehicle, if the main control module determines that the middle seat in the rear row changes from unmanned sitting to manned sitting, the main control module judges that the user enters through the right side vehicle door of the rear row and sits on the middle seat in the rear row.
Step S43: when the entering area is a rear-row area and a plurality of seats in the rear-row seats are changed from unmanned seats to occupied seats, the seats which are close to the entering area and are changed are determined to be seats taken by users carrying the intelligent terminal.
In this embodiment, when the main control module determines that the entering area before the user carrying the intelligent terminal enters the vehicle is a rear-row area, and the seat sensor system determines that the load-bearing change information of a plurality of seats in the rear-row seats is changed from unmanned sitting to manned sitting, the main control module determines that the rear-row seats which are close to the entering area and are changed are seats on which the user carrying the intelligent terminal sits.
For example, when the main control module determines that the user 1 carrying the intelligent terminal arrives at the C area, the user 1 enters the vehicle from outside the vehicle to inside the vehicle through the C area, that is, the entering area of the user 1 is the C area. The user 2 carrying the intelligent terminal arrives at the area D and enters the vehicle from outside the vehicle to inside the vehicle from the area D, namely the entering area of the user 1 is the area D. In t 1 seconds after user 1 and user 2 get into the car simultaneously, if main control module determines that the back row is close to left seat and is changed from unmanned to someone, and the back row middle seat is changed from unmanned to someone, because the seat that is close to entering area C and is changed is close to left seat, the seat that is close to entering area D and is changed is middle seat in the back row, then main control module judges that user 1 gets into and sits in the back row and is close to left seat through back row left side door, user 2 gets into and sits in the back row middle seat through back row right side door.
In this embodiment, the main control module may determine, through the determined access area of the user carrying the intelligent terminal, a front row area and/or a rear row area, and determine, through the seat sensing system, load bearing change information of each front row seat and/or rear row seat in the vehicle, so as to not only determine a specific position of the user in the vehicle when one person takes a vehicle, but also determine a specific riding position of each user in the vehicle when multiple persons take a vehicle, thereby solving the technical problem in the prior art that the riding area of multiple users in the vehicle cannot be determined.
In combination with the above embodiment, in an implementation manner, the embodiment of the invention further provides a method for determining a sitting position of a user. Specifically, the method further includes a position determination after the user changes the position in the vehicle, that is, includes step S51 and step S52 in addition to the above steps:
Step S51: and when the first seat and the second seat in the back row of seats are determined to be changed in sequence, the first seat is changed from the unmanned seat to the unmanned seat, and the second seat is changed from the unmanned seat to the unmanned seat, the user carrying the intelligent terminal is determined to move onto the first seat from the second seat.
In this embodiment, when the main control module determines that two seats in the back row seat are sequentially changed according to the seat weights of the seats in the vehicle acquired from the seat sensor system, and one seat is changed from being occupied to being occupied, and the other seat is changed from being occupied to being occupied, wherein the back row seat changed from being occupied to being occupied is a first seat, and the back row seat changed from being occupied to being occupied is a second seat, that is, the main control module determines that the first seat and the second seat in the back row seat are sequentially changed, and the first seat is changed from being occupied to being occupied, and when the second seat is changed from being occupied to being occupied, the main control module determines that a user carrying the intelligent terminal moves from the second seat to the first seat.
For example, if the user sits in the rear row of the vehicle, when the main control module determines that the leftmost seat is changed from sitting with a person to sitting without a person, and the seat in the middle of the rear row is changed from sitting without a person to sitting with a person, the main control module determines that the user moves from the leftmost seat of the rear row to the middle of the rear row.
Step S52: and when a plurality of seats in the back row seats are determined to be changed simultaneously, determining the seats which are close to the access area and become occupied by people to be the seats occupied by the users carrying the intelligent terminal.
In this embodiment, when the master control module determines that there are multiple seats in the rear seats that change simultaneously, for example, if it is determined that there are two seats in the rear seats that are sitting from occupied to unoccupied in the early period of the first period of time, and that there are two seats in the rear seats that are sitting from unoccupied to occupied in the later period of time of the first period of time, the master control terminal determines that the seat that is close to the entrance area and that becomes occupied is the seat that is occupied by the user carrying the intelligent terminal. It should be noted that, the first time period is a time period for detecting the weight change of the seat, which is set in advance according to manual experience, and the specific time period of the first time period is not limited in this embodiment.
For example, two users 1 and 2 in the back row enter the vehicle from the area C and the area D respectively, the main control module determines that the seat in the middle of the back row is changed from occupied to unoccupied, then determines that the seat in the middle of the back row is changed from unoccupied to occupied, and the main control module determines that the seat in the middle of the back row is changed from unoccupied to occupied, and the seat in the middle of the back row is changed into occupied after the position of the user 1 is changed, and the seat in the middle of the back row is changed into occupied after the position of the user 2 is changed.
In this embodiment, the main control module can also determine the load-bearing change condition of each back row seat in a period of time through the seat sensor system in the vehicle, so as to judge the position of the user after changing the position in the vehicle, thereby not only realizing accurate position judgment after the user enters the vehicle, but also realizing position judgment after the position of the user in the vehicle is changed.
In combination with the above embodiment, in an implementation manner, the embodiment of the invention further provides a method for determining a sitting position of a user. Specifically, in this method, in addition to the above steps, steps S61 and S62 are included:
step S61: and when the near field communication connection is established with the intelligent terminal, acquiring identity information of a user carrying the intelligent terminal.
In this embodiment, when the main control module establishes a close range communication connection with the intelligent terminal, the main control module performs identity authentication with the intelligent terminal to obtain identity information of a user carrying the intelligent terminal. The embodiment may be that the main control module stores registration information of a plurality of users in advance, the registration information of the users includes user identifiers, when the main control module is connected with the intelligent terminal in a short distance, the main control module can send an identity authentication request to the intelligent terminal, the intelligent terminal returns login information of the user carrying the intelligent terminal to the main control module, the main control information matches the received login information with the registration information of the plurality of users stored in advance, after the identity authentication is passed, the main control module determines identity information of the user carrying the intelligent terminal, and the identity information includes the user identifiers.
Step S62: and outputting the seat on which the user carrying the intelligent terminal sits and the identity information of the user.
In this embodiment, after determining the seat on which the user carrying the intelligent terminal sits, the main control module outputs the seat on which the user carrying the intelligent terminal sits and the identity information of the user according to the identity information (e.g., the user identifier) corresponding to the intelligent terminal determined after the identity authentication is performed.
For example, when the main control terminal determines that the seat on which the user 1 carrying the intelligent terminal a sits is the main driving position, the main control terminal also determines that the identity information of the user 1 is the main driving position of the vehicle according to the identity authentication, and the main control terminal outputs that the vehicle claims to sit in the main driving position of the vehicle. For another example, when the main control terminal determines that the seat on which the user 2 carrying the intelligent terminal B sits is a rear-row right seat, and further determines that the identity information of the user 2 is wang according to the identity authentication, the main control terminal outputs wang to sit on the rear-row right seat of the vehicle.
In this embodiment, after the main control module performs identity authentication with the intelligent terminal, the identity information of the user carrying the intelligent terminal is obtained, so that the identity information of the user is determined when the riding position of the user is determined, and the user riding position is determined, and meanwhile the identity of the user is determined.
The method for determining the sitting position of the user according to the embodiment of the present invention is further described below with reference to a specific embodiment:
The position of the rear seat of the vehicle is recorded as the rear seat, the rear row and the rear right. The first portable mobile phone approaches the vehicle from the left area C, the second portable mobile phone approaches the vehicle from the right area D, and two people intend to enter the rear row of the vehicle for riding. When the first part is close to the vehicle, the Bluetooth of the mobile phone is connected with the vehicle main control module, the first part is verified to be a vehicle owner, and the UWB positioning function is started at the same time. The vehicle UWB positioning module determines that the vehicle is entering region C. The first entering vehicle, main control module still is connected with first cell-phone bluetooth, but UWB positioning module can't accurately judge first accurate position, and main control module judges first entering vehicle in this moment be t 0 moment. And at this time, the second part also enters the vehicle. Within 5 seconds after the time t 0, the first and second seats are sequentially arranged on the seat, the main control module judges that the left and right of the rear row are changed from an unmanned state to a manned state through the seat sensor, and the main control module judges that the first seat is arranged at the left position of the rear row and the right of the rear row is close to the region D because the left of the rear row is close to the region C, and the main control module judges that the second seat is arranged at the right position of the rear row.
Because the back row is left and is sun-dried, the nail is changed from the back row left to the back row, the main control module detects that the person is changed into the no person through the back row left seat sensor, and the main control module detects that the person is changed into the person through the back row left seat sensor, so that the main control module judges that the nail is changed from the back row left position to the back row position.
