  By the way, since there are many cases where the driving of the vehicle is forgotten because the switch operation of turning on the power of the device is forgotten, the switch operation is performed so as to further improve the convenience and handling of the device. A device that omits the power supply and keeps the acceleration sensor constantly driven is assumed.

  However, when the acceleration sensor is always driven in a portable device, it may be difficult to distinguish between a change in acceleration when attached to the vehicle and a state where it is removed and carried. There is a problem that the reliability of diagnosis is lowered.

  In addition, when the battery is driven and the power is always on, it is necessary to reduce power consumption by reducing the battery consumption and reducing the calculation processing by the microcomputer (control unit) that consumes a large amount of power inside the device. is there.

  The present invention solves the above-mentioned problems, and is a battery-powered and portable device that can improve the reliability of driving diagnosis and save power, further improving the convenience and handling of the device. An object of the present invention is to provide a driving diagnosis device that can perform the operation.

  In order to achieve the above object, a driving diagnosis apparatus according to the present invention is driven by a battery, acquires driving behavior from the motion of a vehicle detected by a motion detection sensor, determines the driving behavior, and diagnoses the driving. The apparatus main body which has a control part to carry and which can be carried is provided, and the said apparatus main body is installed in the arbitrary places in a vehicle. The operation detection sensor is always in a driving state, and after detecting that the apparatus main body is installed at an arbitrary place in the vehicle, the operation behavior is taken into the control unit based on the detection of the vehicle operation from the operation detection sensor. A driving behavior take-in start unit is provided for starting and determining the driving behavior.

  According to this configuration, the battery can be driven and carried by a battery, and the operation detection sensor that acquires the driving behavior is always in the driving state, so that the convenience and handling of the device can be enhanced. At the same time, since it is detected that the apparatus main body is installed at an arbitrary place in the vehicle, it is easy to distinguish between a state in which the apparatus main body is installed in the vehicle and a state in which the apparatus main body is not installed. In addition, since the driving behavior capture is started and the driving behavior is determined after the driving behavior capturing start unit detects the installation of the apparatus main body, the calculation in the control unit is reduced as much as possible to reduce battery consumption. it can. Thereby, it is a battery-powered apparatus that can be carried and can improve the reliability of operation diagnosis by distinguishing the installation state of the apparatus main body, and can save power, thereby further improving the convenience and handling of the apparatus.

  In the present invention, an installation holder that is installed at an arbitrary location in a vehicle and on which the apparatus main body is detachably mounted, and an installation detection mechanism for detecting that the apparatus main body is mounted on the installation holder. It is preferable that the driving behavior take-in start unit starts driving behavior capturing and determines the driving behavior after detecting the installation of the apparatus main body to the installation holder. In this case, since the attachment detection mechanism detects the attachment of the apparatus main body to the installation holder, it is easy to distinguish between a state in which the apparatus main body is attached to the installation holder in the vehicle and a state in which the apparatus main body is not attached.

  Further, it is also preferable that the mounting detection mechanism comprises a detection switch, and has a switch main body on the apparatus main body side and a detected object on the installation holder side. In this case, attachment to the installation holder can be easily detected on the apparatus main body side.

  Furthermore, the installation holder may be provided with a plurality of types, each having a different holder identifier, and the apparatus main body may have a holder identifier recognition unit for recognizing the holder identifier. In this case, since the type of installation holder can be recognized separately, even if the installation angle differs depending on the type of vehicle, correction of acceleration data corresponding to this becomes easy in advance, and driving behavior can be easily corrected.

  Preferably, the plurality of objects to be detected constitute the holder identifier. Therefore, it is possible to easily detect attachment of the apparatus main body to the installation holder and identify the plurality of installation holders with a simple configuration.

  Preferably, the motion detection sensor is an acceleration sensor, a gyro sensor, or a GPS sensor. Therefore, the driving behavior can be easily acquired.

  The present invention can be carried by being driven by a battery, and since the operation detection sensor for acquiring the driving behavior is always in the driving state, the convenience and handling of the apparatus can be enhanced. At the same time, since it is detected that the apparatus main body is installed at an arbitrary place in the vehicle, it is easy to distinguish between a state in which the apparatus main body is installed in the vehicle and a state in which the apparatus main body is not installed. In addition, since the driving behavior capture is started and the driving behavior is determined after the driving behavior capturing start unit detects the installation of the apparatus main body, the calculation in the control unit is reduced as much as possible to reduce battery consumption. it can.

(A)-(C) are schematic diagrams which show a to-be-detected body (holder identifier) and a switch main body. It is a block block diagram which shows the driving | operation diagnosis apparatus which concerns on 2nd Embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a driving diagnosis apparatus 1 according to the first embodiment of the present invention, and FIG. 2A is an exploded configuration view seen from a side S showing the driving diagnosis apparatus of FIG. B) is a configuration diagram showing the assembled state.

  As shown in FIG. 1, the apparatus 1 includes a portable apparatus body 2 and an installation holder 3 having a recess 3 a for storing the apparatus body 2. The installation holder 3 is disposed in an arbitrary place in the vehicle, for example, the dashboard D, and the apparatus main body 2 is detachably mounted in the recess 3 a of the installation holder 3. On the bottom surface of the installation holder 3, a fixing material (FIG. 2) such as a double-sided tape 24 is provided. The driving diagnosis apparatus 1 has a substantially rectangular parallelepiped shape. When the driving diagnosis apparatus 1 is installed on the plane portion of the dashboard D as shown in FIG. Become.

  As shown in FIG. 3, the apparatus main body 2 includes an operation detection sensor 5 such as an acceleration sensor that detects an operation such as acceleration of a vehicle and obtains driving behavior, a control unit (microcomputer) 6, and a display unit 7. And a battery 8 for supplying power to the apparatus. The apparatus main body 2 is driven by the battery 8 and is always on. In addition, a notification unit, a memory, and a power switch for notifying an alarm (not shown) are also provided. The power switch turns off the power when the apparatus main body 2 is not used for a long time.

  This apparatus 1 acquires driving behavior from the acceleration of the vehicle detected only by the acceleration sensor 5 as an operation detection sensor, without using various sensors together conventionally, and the control part 6 is the acquired driving | operation The determination is calculated based on the behavior and the operation is diagnosed. The memory stores diagnostic results and the like. The driving behavior includes at least a brake operation, an accelerator operation, and a steering operation.

  The acceleration sensor 5 obtains data (G display) of three axes of front, rear, left and right, and upper and lower axes in order to acquire the driving behavior of the vehicle. Among the driving behaviors, for example, sudden acceleration, sudden braking, Detects dangerous behavior of sudden handle (3 sudden), smooth driving behavior such as smooth start and stop. The acceleration sensor 5 is always supplied with power from the battery 8 and is always in a driving state.

  In this example, an acceleration sensor is used as the motion detection sensor, and the driving behavior is acquired based on the acceleration of the vehicle. Instead, for example, a driving behavior is acquired based on the angular velocity of the vehicle using a gyro sensor. In addition, the driving behavior can be acquired by using the GPS sensor and the acceleration due to the speed change of the vehicle over time.

  Since this driving diagnosis apparatus 1 is equipped with a battery 8 such as a lithium battery, wiring for supplying power from the vehicle is unnecessary, and it is easy to install and can be installed at any place in the vehicle. Become. The display unit 7 includes, for example, a liquid crystal display (LCD) or a light emitting diode (LED), and displays a diagnosis result and the like.

  The control unit 6 controls the entire apparatus and includes a driving behavior determination unit 10. Based on the driving behavior, the driving behavior determination unit 10 diagnoses the driving by determining the safe driving and the dangerous driving, for example, based on the continuous number of smooth driving and the dangerous driving or the average number of times. The diagnosis output unit 11 outputs the diagnosis result and displays it on the display unit 7, and also makes an alarm sound (alarm) from the notification unit for dangerous driving.

  The apparatus 1 further includes an attachment detection mechanism 13 for detecting that the apparatus main body 2 is attached to the installation holder 3 and an acceleration sensor 5 to the control unit 6 after detecting the attachment of the apparatus main body 2 to the installation holder 3. And a driving behavior capturing start unit 12 for starting the capturing of driving behavior based on the acceleration (motion) detection of the vehicle and determining the driving behavior. When the driving behavior capturing start unit 12 detects the mounting of the apparatus main body 2, the driving behavior capturing start unit 12 outputs a mounting detection signal to the control unit 6, and the control unit 6 starts capturing the driving behavior based on the input of the mounting detection signal. To do.

  As shown in FIG. 2, the attachment detection mechanism 13 is a detection switch such as a lever (leaf) switch, for example, a switch main body 14 provided on the apparatus main body 2 side, and a protrusion provided on the installation holder 3 side. A to-be-detected body 16. In this example, a contact type switch is used on the assumption that a malfunction or alignment due to vibration is within an allowable range.

  The lever switch 13 has a switch body 14 attached to a support frame 19 on the apparatus body 2 side, and protrudes upward toward the installation holder 3 at a position facing the lever 14a of the switch body 14 when the apparatus body 2 is mounted. A protrusion (detected body) 16 is formed. The apparatus main body 2 is provided with a guide portion 2a below the lever 14a, and the protrusion 16 is guided along the guide portion 2a when mounted.

  Since the protrusion 16 which is a detection object is formed on the installation holder 3 side, the power supply to the installation holder 3 is unnecessary, and the configuration is simplified. As shown in FIG. 4, in this example, there are two lever switches 13, and two protrusions 16 (FIG. 1) are provided, which is also used for a holder identifier 17 described later. . The attachment of the apparatus main body 2 is detected by detecting one of the two lever switches 13. In addition, when using the holder identifier provided separately or when holder identification is unnecessary, the one protrusion 16 is provided.

  As shown in FIG. 1, a lock portion 20 that locks and fixes the apparatus main body 2 to the installation holder 3 when the apparatus main body 2 is mounted is provided. The lock unit 20 has a well-known structure, and includes, for example, a button 21 disposed substantially at the center of the front side on the installation holder 3 side, a claw unit (not shown), and a spring that biases the button 21, and the apparatus body 2 On the side, there are a button receiving portion 22 and a claw locking portion (not shown) for locking the claw portion when locked. When the button of the lock part 20 is pressed, the locking of the claw part is disengaged and the lock is released.

  2 is provided with an engaging portion 2b at a position (left side in the drawing) spaced from the lock portion 20 (right side in the drawing) and adjacent to the protrusion 16 of the installation holder 3. An engaged portion 16 a made of a recess is provided, and when the apparatus main body 2 is mounted, the engaging portion 2 b and the engaged portion 16 a are engaged, and the apparatus main body 2 is attached to the installation holder 3 together with the lock portion 20. Securely fixed. Thereby, the shift | offset | difference of the apparatus main body 2 from the installation holder 3 and the vibration of the apparatus main body 2 accompanying this are prevented.

  When the apparatus body 2 is mounted on the installation holder 3, the lever 16a of the lever switch body 14 is pushed up while the protrusion 16 is guided by the guide 2b, and the switch is turned on. At this time, the apparatus main body 2 is locked and fixed to the installation holder 3 by the lock unit 20. When the button 21 is pressed and the lock is released, the apparatus main body 2 is detached from the installation holder 3 and is switched off. When the apparatus main body 2 is not attached to the installation holder 3, the switch-off state is maintained.

  In this example, a contact lever switch is used as the detection switch, but the present invention is not limited to this, and a magnet switch, a limit switch, or the like may be used. Moreover, you may use the detection sensor (photointerrupter) etc. which detect non-contact-type light interruption. Also in this case, the light emitter / receiver of the detection sensor is arranged on the apparatus main body 2 side, and the detected object is arranged on the installation holder 3 side.

  The installation holder 3 of FIG. 1 is provided with a plurality of types and has different holder identifiers 17, and the apparatus main body 2 has a holder identifier recognition unit 15 that recognizes the holder identifier 17. As shown in FIG. 4, in this example, two lever switches 13 used for mounting detection are provided and used for holder identification. The lever switch 13 is used for both mounting detection and holder identification.

  Three types of installation holders 3 can be identified by the two lever switches 13 and the two projections 16 (17), and the combination of the presence or absence of the two projections 17 as the holder identifier is previously set for each installation holder 3. It is decided to. For example, as shown in FIG. 4A, two protrusions 17 are arranged as H (present) and H (present). 1 and the arrangement of H (present) and L (none) as shown in FIG. 2 and the arrangement of L (none) and H (present) as shown in FIG. 3. The holder identifier recognizing unit 15 identifies the installation holder 3 based on the detection combination based on the detection inputs from the two switch bodies 14. For example, when the switch body 14 detects H (present) and H (present) of the protrusion 17 at the same time, No. in FIG. 1 of the installation holder 3.

  In this example, since the lever switch 13 serves both for mounting detection and holder identification, it is possible to easily detect mounting of the apparatus main body 2 to the installation holder 3 and holder identification of a plurality of installation holders with a simple configuration.

  Note that three or more protrusions 17 may be provided as holder identifiers, and a large variety of installation holders 3 can be identified by increasing the number of combinations.

  Thus, the type of vehicle can be recognized by identifying the installation holder 3 attached to the vehicle. Since the installation location of the installation holder 3 is different depending on the type of vehicle and the installation angle may be different, the acceleration behavior from the acceleration sensor 5 in the apparatus main body 2 is corrected for each type of vehicle to correct the driving behavior. However, it is easy to correct the acceleration data when the holder 3 is identified in advance and the installation angle of the apparatus is known. Thereby, since the kind of installation holder 3 can be recognized separately, the correction | amendment of the driving behavior according to the kind of vehicle can be made easy.

  FIG. 5 is a block configuration diagram showing the driving diagnosis apparatus 1 according to the second embodiment. In the first embodiment, a contact-type lever switch is used, and holder identification is combined with mounting detection, and the combination is performed. However, in the second embodiment, both are not combined and holder identification is performed by device detection. Are provided separately. Other configurations are the same as those of the first embodiment.

  For example, in addition to the contact type as described above, a non-contact type such as a barcode or an IC card is also used as the holder identifier. Also in this case, a reading device is disposed on the apparatus main body 2 side, and a barcode, an IC card, and the like are disposed on the installation holder 3 side.

  As described above, in the present invention, the battery can be driven and carried by a battery, and the motion detection sensor for acquiring the driving behavior is always in the driving state, so that the convenience and handling of the device can be improved. At the same time, since it is detected that the device main body is installed in an arbitrary place in the vehicle, there is a distinction between the state in which the device main body is installed in the vehicle and the state in which the device main body is not installed in the middle of being carried. It becomes easy. In addition, since the driving behavior capture is started and the driving behavior is determined after the driving behavior capturing start unit detects the installation of the apparatus main body, the calculation in the control unit is reduced as much as possible to reduce battery consumption. it can. Thereby, it is a battery-powered apparatus that can be carried and can improve the reliability of operation diagnosis by distinguishing the installation state of the apparatus main body, and can save power, thereby further improving the convenience and handling of the apparatus.

  In each embodiment, the installation holder 3 to which the mounting body 2 is mounted is provided, but the installation holder 3 may be omitted. In this case, the apparatus main body 2 is directly attached to an arbitrary place such as a dashboard D in the vehicle with a fixing material such as double-sided tape or Velcro (registered trademark). For example, if the installation angle of the apparatus main body 2 is known, the detection that the apparatus main body 2 is directly installed can be detected by detecting the installation state using an acceleration sensor.

  In addition, as a detection method of the direct installation of the apparatus main body 2, the vehicle is identified using radio waves such as key authentication radio waves at the time of engine start and vehicle information (vehicle speed, rotation speed, fuel consumption, etc.) Installation detection of the apparatus main body 2 can be performed. In addition, when there is a specific light or sound in each vehicle, the vehicle can be identified by detecting them.

  In addition, in each embodiment, although the kind of installation holder 3 is identified separately, holder identification may be abbreviate | omitted as needed.

  Further, the driving diagnosis apparatus 1 may be provided with a communication function so that the driving behavior diagnosis output, the type of the identified installation holder 3 and the like can be communicated.
