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 may 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 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 embodiment of the present invention, and FIG. 13 shows an electric seat for each user ID stored in advance in the gateway point G, the sensor node SN or the mobile terminal M. FIG. 14 is a flowchart showing an optimum sheet adjustment process, and FIG. 15 is a flowchart showing a power window restriction process. In FIG. 12, FIG. 14 and FIG. 15, S indicates a step.

  In the example shown in FIG. 12, the authority to operate the electric seat and the power window is different for each user based on the ID of the portable terminal possessed by the user (including the driver) who gets into the vehicle. In the present embodiment, the sensor node is provided with a temperature sensor, a pressure sensor that detects the seating of the occupant, and an infrared sensor that detects the seat position by detecting the distance to the reference position of the vehicle body using infrared rays.

  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 of each sensor node SN, the temperature detected by the temperature sensor of each sensor node SN, the sheet position detected by the infrared sensor, and the pressure sensor data of each sensor node are plural. Between these sensor nodes and store their data. 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, the data of the seat position, the respective temperature data detected by the temperature sensor of each sensor node SN, and the data of the pressure sensor are transmitted to the gateway point G. Transmission takes place at the interface.

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

  Next, on the mobile terminal side, in S41, when a user having the 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 S42, 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 hop number of the received beacon node”.
Next, in S43, 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 S44, the position of the mobile terminal M calculated in S42 and the ID of the mobile terminal M are transmitted via the interface of the mobile terminal M. Each sensor node SN relays this transmission data via the interface (S26) and transmits it to the gateway point G.
At the gateway point G, in S32, the location of the mobile terminal M and the ID of the mobile terminal M are received via the interface.

  Here, in each sheet (on each sensor node side), when the user changes the setting of the sheet position (S27), in S28, the sheet readjustment data, and the environment such as temperature accompanying it. The state data is transmitted to the mobile terminal (portable terminal) M closest to the sheet (each sensor node). In the mobile terminal M, in S45, the sheet readjustment data transmitted from each sensor node SN in S28 is received and stored. Also in S29, the sheet readjustment data transmitted to the mobile terminal M in S28 is transmitted to the gateway point G.

Next, in the mobile terminal M, in S46, if the sheet is readjusted, the data of the sheet position is obtained, and if the sheet is not readjusted, the data of the sheet position that was defined first is This transmission data is relayed via the interface of the sensor node SN (S29) and transmitted to the gateway point G. In S46, the identification ID of the mobile terminal M is also transmitted to the gateway point G in the same manner.
In S <b> 46, data related to environmental conditions such as temperature obtained from the sensor node SN is also transmitted to the gateway point G. Also, the data of the seat position in another vehicle stored in the mobile terminal M and the data of the seat position when the vehicle has been boarded in the past are transmitted.

  At the gateway point G, at S33, the mobile terminal M ID and the seat position data (or the temperature data after resetting when resetting) transmitted at S28 or S46 are received. If there is a change in the setting of the sheet position, in S33, the data in the database is rewritten to the data of the sheet position after resetting according to the received ID. The data is, for example, as shown in FIG.

  If the seat position has not been reset, in S34, for each ID (for each user) stored in the database (the memory of the gateway point G (which may be the memory of the sensor node or the memory of the mobile terminal M)). A target seat position is calculated based on the target seat position data. Further, based on the pressure sensor data received in S31, it is determined which seat the occupant is seated on, and the operation of the power window is permitted based on the ID of the mobile terminal M of the occupant seated on the seat. Alternatively, a disapproval is set.

  In the present embodiment, the seat position can be set for each of the plurality of mobile terminals M through a network of sensor nodes. Using this, depending on the seat position set for each occupant, for example, when the seat is greatly reclined and there is an occupant behind it, the reclining amount of the greatly reclined seat is reduced. The seat position may be adjusted between the mobile terminals M, such as readjustment as described above.

  The device control data (table) for each ID (for each user) stored in the database is, for example, as shown in FIG. 13, and for each user ID, the seat position and the power window are permitted or not permitted. Is set. In addition, setting data such as air conditioning settings, navigation settings, or audio equipment is also stored. In this table, a seat position and a power window may be set according to environmental conditions such as temperature. For example, when the temperature is high, the operation of the power window may be changed from non-permission to permission. The table may be stored in any of the memory unit of the gateway point G, the memory unit of the sensor node SN, or the memory unit of the mobile terminal.

  Next, in S35, an optimum adjustment process of the sheet position is performed based on the sheet position data calculated in S34. In this process, as shown in FIG. 14, first, in S51, it is determined whether or not the ID of the mobile terminal M is registered in the table as shown in FIG. If not registered, a temporary ID is assigned in S52, and the process proceeds to S53.

  In S53, the physique of the occupant is estimated from the value of the pressure sensor of each sensor node SN for each seat, and the seat position is controlled. That is, here, the electric seat is operated by the gateway point G so as to be in a predetermined position suitable for the occupant. In addition, if physique data or the like is stored in the mobile terminal M, it may be used.

  If the ID of the mobile terminal M is registered in the table as shown in FIG. 13, the process proceeds to S54, and the gateway point G uses the sheet position data (see FIG. 13) stored for each ID.
