  As shown in FIG. 3, each sensor node SN has a power source such as a button battery, a processor as a CPU, and various sensors built in or attached to the sensor node SN. In the present embodiment, the sensor is a pressure sensor and functions as a seating sensor that detects the seating of an occupant.

In addition to this, there are other methods such as “weak wireless”, “specific low power wireless”, “Bluetooth”, and “UWB”.

  As shown in FIG. 4, the gateway point G includes a power source drawn from the battery of the vehicle, a processor as a CPU, an interface capable of wireless communication with a plurality of sensor nodes SN, a memory, and a device control unit.

This mobile terminal M also forms a network (see FIG. 7) wirelessly with the plurality of sensor nodes SN described above.

Next, the concept of the sensor network will be described.
As described above, the sensor node SN incorporates a memory, an application, a wireless function, and the like in addition to a sensor that performs predetermined sensing. This sensor node SN can hold information obtained by the sensor and can transmit it to other sensor nodes SN wirelessly. With such a function, a certain sensor node SN can also obtain information on other sensor nodes SN, that is, information obtained by sensors included in other sensor nodes SN and stored information. In this way, a plurality of sensor nodes SN are connected by a network (see FIG. 6), and even if one sensor node SN fails, a network can be formed by other sensor nodes SN. This makes it possible to form a network that does not require wiring, unlike in-vehicle LANs that are connected by wiring. In addition, the information of the sensor node SN at a certain position can be obtained from various angles together with the information of other sensor nodes SN.

  According to such a sensor network, for example, when controlling the air conditioning equipment in the vehicle, when the sun is hitting from one side of the car, the passenger who is not hitting the sun is blowing the sun. The temperature can be made lower than that of air blowing. Similarly, navigation, electric seats, and power windows can be changed according to the seating position of the occupant.

  In addition, for example, in an air conditioner, since the sensible temperature varies depending on the person, as will be described later, by using the mobile terminal M possessed by each occupant and detecting the mobile terminal M with the sensor node SN, who is seated where. It can be grasped as information so that an appropriate temperature can be obtained for each passenger. Similarly, the navigation, the electric seat, and the power window may be controlled by the mobile terminal M for on-vehicle equipment suitable for each occupant.

Next, a method for detecting the position of the sensor node SN or the portable terminal M will be described.
In this case, when the user having the mobile terminal M gets on, the position information on which the user is seated is accurately detected. Alternatively, for example, when the sensor node SN is attached to the seat, the seat itself can be arranged in various ways. The position of the sensor node SN whose position has been changed is accurately detected when the position is changed.

First, the first method, “calculated center of gravity of received beacon node”, will be described.
Here, the beacon node is the sensor node SN or the portable terminal M that can transmit / receive predetermined position information, and the node is the sensor node SN or the portable terminal M whose position is not known. Is a sensor node SN or a portable terminal M that has a known position and can transmit and receive predetermined position information. A beacon is a radio signal including position information.

In Centroid (centroid) measurement by centroid calculation, a landmark whose position is known in advance periodically transmits a beacon including its own position information to neighboring nodes. The beacon from the landmark is assumed to be transmitted in a spherical shape, and does not consider the received radio wave intensity. Furthermore, it is assumed that there are many landmarks. A node whose position is not known can know the positions of landmarks existing around from the position information included in the beacon. When the positions (X _i , Y _i ) of N landmarks are acquired, the center of gravity (Xe ^st , Ye ^st ) is calculated by the following equation (1).

This first method will be described with reference to FIGS.
FIG. 8 is a flowchart showing a first method for detecting the position of the sensor node SN or the portable terminal M, and FIG. 9 shows an example of the first method for detecting the position of the sensor node SN or the portable terminal M. FIG. In FIG. 8, S represents a step.
As shown in FIG. 8, first, in the position detection process by the first method, a signal of the position of another sensor node SN or portable terminal M is received in S1. Next, in S2, the center of gravity is calculated by the above-described equation (1). Next, the center of gravity calculated in S2 is set as the own position. In this way, the center of gravity (Xe ^st , Ye ^st ) is obtained, for example, as shown in FIG.

Next, the second method, “calculation of hop count of received beacon node”, will be described.
Here, the node is a sensor node SN or portable terminal M whose position is not known, and the landmark is a sensor node SN or portable terminal M whose position is known and capable of transmitting / receiving predetermined position information. is there.

  In this DV-Hop measurement, the distance from each node to the landmark is estimated from information on the number of hops from the landmark and the average distance of one hop. It is a mechanism that estimates the distance from three or more landmarks and calculates its position by polygon measurement.

  First, as a first stage, each node knows the number of hops from a landmark in the network (refers to a hop counter). The landmark floods the bucket containing its location information. Further, this bucket includes a hop counter that is counted each time relaying.

  Next, as a second step, the landmark informs neighboring nodes of the average distance of one hop. Uses control flooding that relays the "one hop average distance" bucket only once. The distance to the landmark is calculated by multiplying the number of hops obtained in step 1 and the average distance of one hop.

Next, as a third stage, the distance from three or more landmarks is calculated and the position is measured by polygon measurement. A method for calculating the average distance of one hop will be described. A bucket flooded with one landmark has arrived at another landmark. A landmark can calculate the physical distance between two points from its own coordinates and the coordinates of other landmarks. Further, since the number of hops (h) to the landmark is known, a value obtained by dividing the physical distance by the number of hops is calculated as a sample of the average distance of one hop. By performing this sample acquisition process on all other landmarks, the samples can be averaged to calculate a one-hop distance. This can be calculated by the following equation (2).

This second method will be described with reference to FIGS.
FIG. 10 is a flowchart showing a second method for detecting the position of the sensor node SN or the portable terminal M, and FIG. 11 shows an example of the second method for detecting the position of the sensor node SN or the portable terminal M. FIG. In FIG. 10, S represents a step.

  As shown in FIG. 10, first, in the position detection process by the first method, a signal of the position of another sensor node SN or portable terminal M is received in S11. Next, in S12, an average distance of one hop is received. Next, in S13, the distance to the sensor node SN or the portable terminal M is calculated from the integration of the number of hops and the average distance of one hop. Next, in S14, the distance from three or more sensor nodes SN or the portable terminal M is calculated, the position is measured by polygon measurement, and set as the own position. In this way, for example, the position of the node is obtained as shown in FIG.

Next, an example of control contents of the in-vehicle device control apparatus according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 12 is a flowchart showing the control contents of the in-vehicle device control apparatus according to the first embodiment of the present invention, and FIG. 13 is a diagram showing an example of the position of the monitor and the position of the occupant provided in the vehicle. In FIG. 12, S indicates a step.
In the example shown in FIG. 12, a pressure sensor is provided in each sensor node SN as a seating sensor, and an operation authority determining person is determined by a seating position based on the detection result of those pressure sensors. For example, the driver seat occupant is determined as the operation restriction determiner.

  First, as shown in FIG. 12, in S21, a plurality of sensor nodes SN (see FIG. 1 and FIG. 2) installed in the vehicle interior form a sensor network by the function of the sensor nodes SN. In S21, each sensor node SN recognizes another sensor node SN and autonomously forms a network. In this network, when a new sensor node SN is installed, the sensor node SN is autonomously added to the network, or when a certain sensor node SN disappears from the network, the sensor node SN autonomously It has an ad hoc function of deleting an SN from the network.

  Next, in S22, relay processing of another sensor node SN is performed. In S22, each sensor node SN autonomously establishes a communication path (routing) to another sensor node SN and relays the data sent from the other sensor node SN to the other sensor node SN. To do. This is a function called a multi-hop function.

  Next, in S23, the position detection process of each sensor node SN is performed by the above-described “calculation of the center of gravity of the received beacon node” or “calculation of the number of hops of the received beacon node”. When the position is known in advance, for example, when the sensor node SN is installed on a seat or roof where the position is fixed, the installation position is registered in the memory of the sensor node SN in advance. You can keep it. Further, after the position detection process is performed once, the position may be stored in the memory, and when the position detection process is performed again, the position stored in the memory may be set.

  Next, in S24, the position data of each sensor node SN and the data indicating whether or not each of the sensor nodes SN is seated are received between the plurality of sensor nodes and the data are received. Remember. Transmission / reception is performed by the interface, and the memory is stored in the memory.

  Next, in S25, the position data of each sensor node SN and the respective data detected by the pressure sensor of each sensor node SN are transmitted to the gateway point G. Transmission takes place at the interface.

  Next, in the gateway point G, in S31, the position data of each sensor node SN transmitted from each sensor node SN in S25 and the respective data detected by the pressure sensor of each sensor node SN are received, Remember. Reception takes place at the interface, and storage is stored in memory.

  Next, in S32, data indicating whether or not seated is detected by the pressure sensor of each sensor node SN and the position of the seated seat are determined, and the operation authority determining data corresponding to the position of each seat is determined from the database. Is read. The database is one or both of the memory of the gateway point G and the memory of the sensor node.

  For example, when the occupant gets on the driver's seat, the operation authority determination data is used to determine whether or not various in-vehicle devices can be operated by other occupants of the other seats with the driver as an operation authority determiner (administrator). It is data of. In addition, the operation authority determination data is data that stores whether or not various types of in-vehicle devices operated by a passenger seated in another seat such as a passenger seat can be operated.

  Next, in S33, the in-vehicle device operation monitor screen at each seat position is displayed based on the operation authority determination data. In the example shown in FIG. 13, screens A to D are provided in the passenger compartment, and the operation screens of the in-vehicle devices within the range of the operation authority permitted to the occupant of each seat are displayed on the respective screens. Mainly, on the screen B for the driver's seat, an operation screen is displayed so that the driver can set all the devices. On the other hand, in accordance with traffic regulations, screen B cannot be displayed on the screen B, but there is a restriction that the screen A for the passenger seat can be displayed on the screen.

  Next, an example of control contents of the in-vehicle device control apparatus according to the second embodiment of the present invention will be described with reference to FIGS. FIG. 14 is a flowchart showing the control contents of the in-vehicle device control apparatus according to the second embodiment of the present invention, and FIG. 15 shows the operation authority of the in-vehicle device for each user stored in advance in the gateway point G or the sensor node SN. It is a figure which shows the table for determining. In FIG. 14, S indicates a step.

  In the example shown in FIG. 14, the authority to operate the in-vehicle device is made different for each user based on the ID of the portable terminal possessed by the user (including the driver) who gets into the vehicle.

  First, as shown in FIG. 14, in S41, a plurality of sensor nodes SN (see FIG. 1 and FIG. 2) installed in the vehicle interior form a sensor network by the functions of the sensor nodes SN. In S41, each sensor node SN has an ad hoc function as described above. Next, in S42, relay processing of another sensor node SN is performed. In S42, each sensor node SN has the multi-hop function as described above.

  Next, in S43, the position detection processing of each sensor node SN is performed by the above-described “calculation of the center of gravity of the received beacon node” or “calculation of the number of hops of the received beacon node”. When the position is known in advance, for example, when the sensor node SN is installed on a seat or roof where the position is fixed, the installation position is registered in the memory of the sensor node SN in advance. You can keep it.

  Next, in S44, the position data of each sensor node SN and the respective data detected by the pressure sensor of each sensor node SN are received between a plurality of sensor nodes and stored. Transmission / reception is performed by the interface, and the memory is stored in the memory.

  Next, in S45, the position data of each sensor node SN and the respective data detected by the pressure sensor of each sensor node SN are transmitted to the gateway point G. Transmission takes place at the interface.

  Next, in the gateway point G, in S51, the position data of each sensor node SN transmitted from each sensor node SN in S45 and the respective data detected by the pressure sensor of each sensor node SN are received, Remember. Reception takes place at the interface, and storage is stored in memory.

  Next, on the mobile terminal side, in S61, when a user having a mobile terminal (mobile terminal) M gets into the vehicle, a plurality of sensor nodes SN (see FIG. 1 and FIG. 2) installed in the vehicle interior are displayed. A sensor network including the mobile terminal M is formed by the function of the sensor node SN (ad hoc function and multi-hop function as described above).

Next, in S62, the position detection process of the user's mobile terminal M is performed by the above-described “calculation of the center of gravity of the received beacon node” or “calculation of the number of hops of the received beacon node”.
Next, in S63, the ID of the mobile terminal M is detected via the interface of each sensor node SN and the interface of the mobile terminal M. That is, it is determined which user has boarded.

Next, in S64, the location of the mobile terminal M calculated in S62 and the ID of the mobile terminal M are transmitted via the interface of the mobile terminal M. Each sensor node SN relays the transmission data via the interface (S46) and transmits it to the gateway point G.
In S52, the gateway point G receives the location of the mobile terminal M and the ID of the mobile terminal M via the interface.

  In the gateway point G, in S53, the ID of the mobile terminal M received in S52 is collated with the ID in the operation authority data for each user stored (registered) in the database. The database is one or both of the memory of the gateway point G and the memory of the sensor node.

  The operation authority data (table) for each ID (for each user) stored in the database is, for example, as shown in FIG. 15, and can be set for all in-vehicle devices. Data such as a restricted mode with restrictions and a full mode in which almost all in-vehicle devices can be set are set for each ID.

Next, in S54, it is determined whether or not the ID of the mobile terminal M received in S52 is included (registered) in the ID in the operation authority data for each user stored in the database.
When the ID of the mobile terminal M received in S52 is included in the ID in the operation authority data for each user stored in the database, the process proceeds to S55 and stored in the database as shown in FIG. The operation authority for each ID is read from the table. Based on the read data, the screen closest to the ID of the mobile terminal M received in S52 among the screens as shown in FIG. 13 is changed according to the operation authority.

  In S54, if the ID of the mobile terminal M received in S52 is not included in the ID in the operation authority data for each user stored in the database, the process proceeds to S56 and the mobile terminal M is assigned a temporary ID. And register. In this case, the table shown in FIG. 15 registers temporary ID data with relatively limited operational authority. In S55, the screen is displayed or changed according to the data.
