Japanese Patent Laid-Open No. 06-206476

  By the way, in a situation where a plurality of users can use one vehicle as a driver, the conventional apparatus cannot determine who the driver is among the plurality of users. If it is possible to determine who is the driver among the plurality of users, various settings of the vehicle can be performed in accordance with each driver.

  Therefore, an object of the present invention is to provide a driver discrimination system that can discriminate who is a driver among a plurality of users in a situation where a plurality of users can use one vehicle as a driver.

  A driver discrimination system according to an embodiment of the present invention is disposed in a driver's seat of a vehicle, detects a weight applied to the driver's seat, and is disposed in a seat other than the driver's seat of the vehicle, An occupant detection unit that detects the presence or absence of an occupant in a seat other than the driver's seat, a plurality of identifiers that identify wireless communication terminals of a plurality of drivers, and a plurality of weight data representing the weights of the plurality of drivers, respectively A storage unit that stores a linked database; an identifier acquisition unit that acquires the identifier by wireless communication from at least one of the wireless communication terminals of the plurality of drivers in the interior of the vehicle; and When two or more identifiers are acquired by the identifier acquiring unit, a reading unit that reads out two or more weight data associated with the acquired two or more identifiers in the database Of the weights represented by the two or more weight data, an identifier associated with the weight data having a difference from the weight detected by the weight sensor equal to or less than a predetermined value in the database And a discriminator that discriminates as an identifier of the communication terminal.

  In this way, when two or more identifiers are acquired by the identifier acquisition unit, in order to read out two or more weight data linked in the database to the two or more acquired identifiers, Using the identifiers of the wireless communication terminals existing in the room and the identifiers registered in the database, it is possible to collate drivers and passengers in the passenger compartment.

  Then, among the weights represented by the two or more weight data, an identifier associated with the weight data in which the difference from the weight detected by the weight sensor is equal to or less than a predetermined value is stored in the database of the driver's wireless communication terminal. Since it is determined as the identifier, the identifier of the driver's wireless communication terminal can be accurately determined even if there is a passenger carrying the wireless communication terminal in addition to the driver in the passenger compartment.

  In a situation where a plurality of users can use one vehicle as a driver, it is possible to provide a driver determination system that can determine who is a driver among a plurality of users.

It is a figure showing vehicle 10 carrying driver discriminating system 100 of an embodiment. It is a figure explaining a mode that data is registered into a database of memory. It is a figure explaining the process which discriminate | determines the driver | operator which ECU110 performs. It is a flowchart which shows the control process (process which discriminates a driver) which ECU110 performs.

  Embodiments to which the driver discrimination system of the present invention is applied will be described below.

<Embodiment>
FIG. 1 is a diagram illustrating a vehicle 10 equipped with a driver discrimination system 100 according to an embodiment.

  The vehicle 10 is, for example, an HV (Hybrid Vehicle) vehicle, a PHV (Plug-in Hybrid Vehicle) vehicle, an EV (Electric Vehicle) vehicle, a gasoline engine vehicle, or a diesel engine vehicle. FIG. 1 shows a driver seat 11D, a passenger seat 11P, a rear seat 11RL, 11RC, and 11RR of the vehicle 10.

  The driver discrimination system 100 includes an ECU (Electric Control Unit) 110, a weight sensor 120, pressure sensors 130P, 130RL, 130RC, 130RR, and a navigation device 140.

  ECU110 is a control part of driver discriminating system 100, and performs processing which discriminates a driver. The ECU 110 is configured by a computer with a built-in memory, and includes a main control unit 111, a registration unit 112, a determination unit 113, and a memory 114.

  Among the components of the ECU 110, the main control unit 111, the registration unit 112, and the determination unit 113 are main functional blocks that are realized when the computer of the ECU 110 executes a program stored in the memory 114. is there. The memory 114 is a part of the memory built in the computer of the ECU 110.

  In FIG. 1, ECU 110 is shown separately from navigation device 140, but ECU 110 may be incorporated in navigation device 140. In this case, ECU 110 may be an ECU (navigation ECU) of navigation device 140, in other words, ECU 110 may be integrated with the ECU of navigation device 140.

  The main control unit 111 is a control unit that supervises control processing (processing for determining a driver) executed by the ECU 110. In addition, the main control unit 111 executes several processes different from the processes performed by the registration unit 112 and the determination unit 113.

  The registration unit 112 performs processing for associating weight data representing the weight of the driver with the identifier of the driver's wireless communication terminal in the memory 114. In other words, the registration unit 112 creates a database in the memory 114 in which weight data representing the weight of the driver and an identifier of the driver's wireless communication terminal are linked.

  The driver discrimination system 100 uses the weight of the driver detected by the weight sensor 120 to authenticate (verify) the driver, so that the driver discrimination system 100 performs the process of discriminating the driver. This is because weight data representing the weight of the driver is necessary.

  In addition, the registration unit 112 performs a process of updating and registering the weight data for the driver who has already registered the weight data and the identifier in the memory 114. This is because when the weight changes, the weight data registered in the memory 114 is overwritten with the latest weight data and registered again.

  The wireless communication terminal is, for example, a smart phone terminal or a mobile phone terminal, has a unique identifier of the terminal, and is paired with the navigation device 140 by short-range wireless communication such as Bluetooth (registered trademark). Thus, any device can be used as long as the navigation device 140 can read the identifier. For this reason, the wireless communication terminal may be, for example, a game machine or other portable device having a short-range wireless communication function.

  The unique identifier is a Bluetooth address (BD_ADDR), a serial number of the terminal, an ID (Identification), or the like. The unique identifier is read by the navigation device 140 when the wireless communication terminal and the navigation device 140 are paired by short-range wireless communication.

  When using a LAN (Local Area Network) instead of short-range wireless communication, the unique identifier of the terminal is a WiFi address (MAC address).

  In the following, a mode in which the wireless communication terminal is a smartphone terminal and the unique identifier is a Bluetooth address (BD_ADDR) will be described as an example. Therefore, the registration unit 112 creates a database in the memory 114 in which weight data representing the weight of the driver is associated with the Bluetooth address (BD_ADDR) of the driver's smartphone terminal.

  The determination unit 113 detects the driver's weight detected by the weight sensor 120, the presence / absence of pressure detected by the pressure-sensitive sensors 130P, 130RL, 130RC, and 130RR (presence / absence of occupants) and the navigation device 140 in the vehicle interior. Based on the Bluetooth address (BD_ADDR) to be executed and the database stored in the memory 114, a process for determining the driver is executed.

  The discriminating unit 113 detects the driver's weight by the weight sensor 120 and does not detect the presence of an occupant by any of the pressure-sensitive sensors 130P, 130RL, 130RC, and 130RR. When one Bluetooth address (BD_ADDR) is detected in the passenger compartment and the detected Bluetooth address (BD_ADDR) is stored in the memory 114, the detected Bluetooth address (BD_ADDR) is stored in the memory 114. It is determined that the user linked inside is the driver.

  Further, the determination unit 113 detects the driver's weight by the weight sensor 120, and detects that there is an occupant by at least one of the pressure sensitive sensors 130P, 130RL, 130RC, and 130RR. Further, in a situation where a plurality of Bluetooth addresses (BD_ADDR) detected in the passenger compartment by the navigation device 140 are stored in the memory 114, processing for determining the driver is performed as follows.

  In the above situation, the determination unit 113 includes a plurality of weight data associated with a plurality of Bluetooth addresses (BD_ADDR) detected by the navigation device 140 inside the memory 114, and a driver detected by the weight sensor 120. The Bluetooth address (BD_ADDR) associated with one weight data whose difference from the body weight is less than the predetermined value, or the weight data with the smallest weight difference among the plurality of weight data whose weight difference is the predetermined value or less. The attached Bluetooth address (BD_ADDR) is determined as the Bluetooth address (BD_ADDR) of the driver's smartphone terminal.

  Here, the weight data having the weight difference equal to or smaller than the predetermined value is selected because the weight closest to the weight of the driver detected by the weight sensor 120 is selected. When there is one weight data whose weight difference is equal to or less than a predetermined value, the Bluetooth address (BD_ADDR) associated with the weight data is determined as the Bluetooth address (BD_ADDR) of the driver's smartphone terminal. . For example, the predetermined value may be set to an absolute value of about 3% to 5% of the body weight. This is in consideration of differences due to clothes worn and detection errors.

  In addition, when there are multiple weight data with a weight difference of a predetermined value or less, the Bluetooth address (BD_ADDR) associated with the weight data with the smallest weight difference is used as the Bluetooth address (BD_ADDR) of the driver's smartphone terminal. Determine.

  When there are a plurality of weight data having a weight difference of a predetermined value or less, the weight data having the smallest weight difference is selected because the difference from the driver's own weight measured by the weight sensor 120 represents the smallest weight. This is because the weight data is considered to be the person's weight.

  In addition to a program necessary for the ECU 110 to execute a control process (a process for determining a driver), the memory 114 includes setting data for the vehicle 10 (settings for the navigation device 140 (detailed settings for route guidance, display modes, etc.). ) For each driver, data indicating the positions of the seat, steering, side mirror, etc. for each driver), and a program necessary for executing a process for determining the driver. The memory 114 is an example of a storage unit. In the setting data, data as described above for a plurality of drivers can be registered.

  The weight sensor 120 is attached to the driver seat 11D and detects the weight applied to the driver seat 11D. The weight sensor 120 is electrically connected to the ECU 110 and outputs weight data representing the weight to the ECU 110.

  The pressure-sensitive sensors 130P, 130RL, 130RC, and 130RR are attached to the passenger seat 11P and the rear seats 11RL, 11RC, and 11RR, respectively, and detect the presence or absence of pressing due to the passenger sitting. That is, it is possible to determine whether there are passengers in the passenger seat 11P, the rear seats 11RL, 11RC, and 11RR based on the detection signals of the pressure sensors 130P, 130RL, 130RC, and 130RR. The pressure sensitive sensors 130P, 130RL, 130RC, and 130RR are electrically connected to the ECU 110, and a detection signal is output to the ECU 110. The pressure sensors 130P, 130RL, 130RC, and 130RR are examples of the occupant detection unit.

  The navigation device 140 detects the latitude and longitude of the current location of the vehicle 10 based on a signal acquired from a GPS (Global Positioning System) satellite, and outputs position data representing the latitude and longitude of the current location. As an example, the navigation device 140 is disposed near the center of the dashboard of the vehicle 10 and may be integrated with an operation unit of an audio or air conditioner.

  The navigation device 140 has a built-in Bluetooth (registered trademark) modem, and can perform short-range data communication by pairing with a smartphone terminal of a driver or another occupant. The navigation device 140 reads the Bluetooth address (BD_ADDR) of the smart phone terminal paired in the vehicle interior and transmits it to the ECU 110. Such a Bluetooth address (BD_ADDR) is read (acquired) by the communication unit of the navigation device 140. The communication unit of the navigation device 140 is an example of an identifier acquisition unit.

  Note that the ECU (navigation ECU) and the ECU 110 of the navigation device 140 are connected to each other via a CAN (Controller Area Network) so that data communication is possible.

  FIG. 2 is a diagram for explaining how data is registered in the database of the memory 114.

  In FIG. 2, the driver 1 is sitting in the driver's seat 11D, and there are no passengers in the passenger seat 11P, the rear seats 11RL, 11RC, and 11RR. The driver 1 has a smartphone terminal 1S. The Bluetooth address (BD_ADDR) of the smartphone terminal 1S is ABC, and the weight of the driver 1 is 60.0 kg.

  In such a case, the weight of the driver 1 (60.0 kg) is detected by the weight sensor 120, and the Bluetooth address (BD_ADDR) (ABC) of the smartphone terminal 1S is read by the communication unit of the navigation device 140.

  The registration unit 112 associates ABC, which is the Bluetooth address (BD_ADDR) of the smartphone terminal 1S, with weight data representing the weight (60.0 kg) of the driver 1 and registers the data in the database of the memory 114.

  In addition, in the state where ABC which is a Bluetooth address (BD_ADDR) and the weight of the driver 1 (60.0 kg) are registered in the database as described above, when the driver 1 is fat and the weight increases. The ECU 110 performs the following update registration process.

  In the state where ABC, which is the Bluetooth address (BD_ADDR) of the smartphone terminal 1S, and weight data representing the weight (60.0 kg) of the driver 1 are linked and registered in advance in the database, the weight sensor 120 When the weight (62.0 kg) of the driver 1 is detected and the Bluetooth address (BD_ADDR) (ABC) of the smartphone terminal 1S is read by the communication unit of the navigation device 140, the registration unit 112 The weight of the driver 1 associated with ABC which is the Bluetooth address (BD_ADDR) of the smartphone terminal 1S is updated to 62.0 kg.

  FIG. 3 is a diagram illustrating a process for determining a driver executed by the ECU 110.

  In FIG. 3, the driver 1 is sitting in the driver's seat 11D, the passengers 2 and 3 are sitting in the passenger seat 11P and the rear seat 11RL, respectively, and there are no passengers in the rear seats 11RC and 11RR. The Bluetooth address (BD_ADDR) and the weight of the smartphone terminal 1S of the driver 1 are the same as those in FIG.

  The occupants 2 and 3 have smartphone terminals 2S and 3S, respectively, and the Bluetooth addresses (BD_ADDR) of the smartphone terminals 2S and 3S are ABD and ABE, respectively, and the weights of the occupants 2 and 3 are They are 50.0 kg and 70.0 kg, respectively.

  Each of the passengers 2 and 3 registers a Bluetooth address (BD_ADDR) and weight in the database as a driver. Therefore, in FIG. 3, the ABC that is the Bluetooth address (BD_ADDR) of the smartphone terminal 1 </ b> S and the weight data representing the weight (60.0 kg) of the driver 1 are registered in the database of the memory 114 in association with each other. In addition, the Bluetooth addresses (BD_ADDR) (ABD, ABE) of the smartphone terminals 2S and 3S and the weights (50.0 kg, 70.0 kg) of the passengers 2 and 3 are registered in association with each other.

  Such a situation is, for example, in a family where three members of the family (father, mother, son) use the vehicle 10 as a driver, the father sits in the driver's seat 11D as the driver 1, and the mother as the passenger 2 This may occur when the son is sitting at 11P and the son is sitting at the rear seat 11RL as the passenger 3. Then, it is assumed that the Bluetooth addresses (BD_ADDR) (ABC, ABD, ABE) of the father, mother, and son smartphone terminals 1S, 2S, and 3S are read by the communication unit of the navigation device 140. This situation may also occur when a plurality of employees get on a vehicle for corporate use.

  In such a case, the weight of the driver 1 (60.0 kg) is detected by the weight sensor 120, and the Bluetooth addresses (BD_ADDR) (ABC, ABD, ABE) of the smartphone terminals 1S, 2S, 3S are stored in the navigation device 140. It is read by the communication unit and transmitted to the ECU 110.

  The determination unit 113 receives weight data (60.0 kg, 50.0 kg, 70.0 kg) associated with the Bluetooth address (BD_ADDR) (ABC, ABD, ABE) received from the navigation device 140 in the database of the memory 114. ) And the Bluetooth address (BD_ADDR) (ABC) associated with the weight data whose difference from the weight of the driver 1 (60.0 kg) is equal to or less than a predetermined value by the weight sensor 120 is determined as the Bluetooth address (BD_ADDR) of the driver. ). Here, the predetermined value is, for example, 3.0 kg.

  Therefore, the ECU 110 determines that the user (driver 1) who has the smartphone terminal 1S is sitting in the driver's seat 11D, and the setting associated with the Bluetooth address (BD_ADDR) (ABC) from the memory 114. Data (data representing the settings of the navigation device 140 (detailed settings for route guidance, display mode, etc.) for each driver, and data representing the positions of the seat, steering, side mirror, etc. for each driver) It is set together.

  FIG. 4 is a flowchart showing a control process (a process for determining a driver) executed by the ECU 110. The process of discriminating the driver is executed by the main control unit 111, the registration unit 112, and the discrimination unit 113.

  For example, when the ignition switch is turned on, the main control unit 111 starts processing (start).

  The main control unit 111 causes the weight sensor 120 to measure the weight and causes the pressure sensitive sensors 130P, 130RL, 130RC, and 130RR to detect the pressing force (step S1).

  Based on the detection results of the pressure sensors 130P, 130RL, 130RC, and 130RR, the main control unit 111 determines whether there is a passenger in the passenger seat 11P, the rear seats 11RL, 11RC, and 11RR (step S2).

  If the main control unit 111 determines that no passenger is present in any of the passenger seat 11P, the rear seats 11RL, 11RC, and 11RR (S2: NO), whether or not the Bluetooth address (BD_ADDR) of the smartphone terminal is detected in the vehicle interior Is determined (step S3). In step S3, the main control unit 111 causes the communication unit of the navigation device 140 to perform proximity communication using Bluetooth (registered trademark) to detect the Bluetooth address (BD_ADDR) of the smartphone terminal in the vehicle interior.

  If the main control unit 111 determines that the Bluetooth address (BD_ADDR) has been detected (S3: YES), the main control unit 111 causes the registration unit 112 to determine whether the Bluetooth address (BD_ADDR) is registered in the database of the memory 114 (step S4). ).

  If the registration unit 112 determines that it is not the registered Bluetooth address (BD_ADDR) (S4: NO), the weight data acquired in step S1 and the Bluetooth address (BD_ADDR) are linked and registered in the database of the memory 114 ( Step S5).

  On the other hand, when the registration unit 112 determines that it is the registered Bluetooth address (BD_ADDR) (S4: YES), the weight data of the database linked to the Bluetooth address (BD_ADDR) is converted into the weight data acquired in step S1. Update (step S5).

  After completing step S4 or S5, the main control unit 111 sets the setting data of the vehicle 10 (data indicating the settings of the navigation device 140 (detailed settings for route guidance, display mode, etc.) for each driver, seats, steering, The driver 1 is requested to input data indicating the position of the side mirror or the like for each driver (step S7). As a result, the driver 1 is requested to input the setting data by display on the monitor of the navigation device 140 and voice guidance, and when the driver 1 completes the setting of the setting data, the flow ends (END). At this time, the settings of the navigation device 140, the seat, etc. are held in the state set by the setting data.

  Further, when the main control unit 111 determines that at least one of the passenger seat 11P, the rear seats 11RL, 11RC, and 11RR has an occupant (S2: YES), the Bluetooth address (BD_ADDR) of the smartphone terminal in the vehicle interior Is detected (step S8). In step S8, the main control unit 111 causes the communication unit of the navigation device 140 to perform proximity communication using Bluetooth (registered trademark) to detect the Bluetooth address (BD_ADDR) of the smartphone terminal in the vehicle interior.

  When determining that the Bluetooth address (BD_ADDR) is detected (S8: YES), the main control unit 111 determines whether there are a plurality of detected Bluetooth addresses (BD_ADDR) (step S9).

  If the main control unit 111 determines that the detected Bluetooth address (BD_ADDR) is not plural (one) (S9: NO), the main control unit 111 indicates that the Bluetooth address (BD_ADDR) is the driver's smartphone. It is determined that the terminal is the one (step S10).

  On the other hand, if the main control unit 111 determines that there are a plurality of detected Bluetooth addresses (BD_ADDR) (S9: YES), the main control unit 111 displays the weight data associated with the plurality of Bluetooth addresses (BD_ADDR) in the database. Read (step S11). The main control unit 111 that performs the process of step S11 is an example of a reading unit.

  The determination unit 113 determines whether there is a plurality of weight data in which the difference from the weight of the driver detected by the weight sensor 120 is equal to or less than a predetermined value among the weight data (step S12).

  If the determination unit 113 determines that there is not a plurality of weight data (S12: NO), the determination unit 113 determines the Bluetooth address (BD_ADDR) associated with only one weight data as the driver's Bluetooth address (BD_ADDR) ( Step S13).

  If the determination unit 113 determines that there are a plurality of weight data (S12: YES), the Bluetooth address (BD_ADDR) associated with the weight data having the smallest difference from the weight of the driver detected by the weight sensor 120 is determined. It discriminate | determines as a driver | operator's Bluetooth address (BD_ADDR) (step S14).

  When the main control unit 111 finishes the process of step S13 or S14, the main control unit 111 ends the flow (end).

  If the Bluetooth address (BD_ADDR) is not detected in steps S3 and S8 (S3, S8: NO), the main control unit 111 ends the flow (end). This is because there is no smartphone terminal paired with the navigation device 140.

  As described above, the driver discrimination system 100 according to the embodiment has a passenger in addition to the driver 1, Bluetooth addresses (BD_ADDR) of a plurality of smartphone terminals are detected in the vehicle interior, and a plurality of Bluetooth When the address (BD_ADDR) is registered in the database of the memory 114, the weight sensor 120 detects the weight represented by the weight data associated with a plurality of Bluetooth addresses (BD_ADDR) in the database. The user of the Bluetooth address (BD_ADDR) linked to one weight data whose difference from the current weight is less than the predetermined value, or the weight with the smallest weight difference among a plurality of weight data whose weight difference is the predetermined value or less The user of the Bluetooth address (BD_ADDR) linked to the data is identified as the driver.

  Therefore, the setting data registered in the memory 114 (data indicating the settings of the navigation device 140 (detailed settings for route guidance, display mode, etc.) for each driver, and the positions of the seat, steering, side mirror, etc. The data of the user of the determined Bluetooth address (BD_ADDR) can be read out from the data and the navigation device 140, the seat position, etc. can be set.

  Therefore, it is possible to provide a driver discrimination system 100 that can discriminate who is a driver among a plurality of users in a situation where a plurality of users can use one vehicle 10 as a driver.

  The driver discriminating system 100 registers the Bluetooth addresses (BD_ADDR) and weights of a plurality of users who can become drivers in association with the database in the memory 114 in advance, and the weight sensor of the driver's seat 11D. The user of the Bluetooth address (BD_ADDR) linked to one weight data whose difference from the weight measured at 120 is a predetermined value or less, or the weight difference among a plurality of weight data whose weight difference is a predetermined value or less. Since the user of the Bluetooth address (BD_ADDR) associated with the minimum weight data is determined as the driver, the driver can be determined with very high accuracy.

  For this reason, from the setting data (data representing the settings of the navigation device 140 (detailed settings for route guidance, display mode, etc.) for each driver, and data representing the positions of the seat, steering, side mirror, etc. for each driver) The driver data can be read with high accuracy, and the navigation device 140, the seat position, and the like can be set.

  In the above description, the pressure-sensitive sensors 130P, 130RL, 130RC, and 130RR are used as the occupant detection unit. However, the sensors that detect whether the passenger seat 11P, the rear seats 11RL, 11RC, and 11RR are worn are used. You may use as a passenger | crew detection part.

  If a plurality of Bluetooth addresses (BD_ADDR) are detected in step S3, a plurality of Bluetooth addresses (BD_ADDR) are registered in the database in step S5, or a plurality of Bluetooth addresses (BD_ADDR) in step S6. What is necessary is just to update weight data.

  The driver discrimination system according to the exemplary embodiment of the present invention has been described above, but the present invention is not limited to the specifically disclosed embodiment, and departs from the scope of the claims. Various modifications and changes are possible.
