  The present invention relates to a vehicle personal authentication apparatus for identifying a person to be identified based on imaging information from an imaging means provided in a vehicle, and can perform personal authentication using biometric features without troublesome work. .

  Hereinafter, embodiments of the present invention will be described based on specific examples shown in the drawings.

  As shown in FIG. 1, the vehicle personal authentication device includes an operation means 1, an imaging means 2, a control means 3, and a display means 4.

  The operation means 1 emits an operation signal to the control means 3 in response to a predetermined operation by a vehicle user, and a touch panel provided on the instrument panel of the vehicle can be applied. The operation means 1 can display a desired button and can issue an operation signal by touching the button.

  The imaging means 2 can be a camera using an element such as a CCD or a CMOS, and is provided at a position where a vehicle user who has boarded the driver's seat can be imaged. In this case, the image pickup means 2 is provided in the vicinity of the operation means 1 of the instrument panel, and is configured to output information picked up at predetermined intervals to the control means 3.

  The control means 3 can be a microcomputer, is connected to a device such as a CAN (Controller Area Network) communication cable or an ignition switch, and inputs signals from the operation means 1 and the imaging means 2 and various vehicle information, etc. In response to this signal, a drive signal for controlling the display means 4 and a vehicle control device to be described later is generated and output.

  The control means 3 includes a CPU for performing arithmetic processing based on various information, a readable / rewritable RAM for temporarily storing arithmetic processing results and the like in the CPU, and a ROM for storing control programs and control data. And a driver IC that generates and outputs a drive signal based on the calculation by the calculation process, and an input / output interface connected to exchange the various information. The storage unit stores in advance identification information (iris information) of a user who is permitted to use the vehicle for a driving operation. The control means 3 can also be used as a control means for displaying and outputting measured values such as the vehicle travel speed, the accumulated travel distance, and the remaining fuel amount in accordance with various information from the vehicle.

  The display unit 4 performs a desired display based on a control signal from the control unit 3, and in this case, the display unit 4 can also be applied as a touch panel of the operation unit 1. Note that this touch panel can also be used as a display device for displaying a measured value such as the traveling speed of the vehicle and displaying navigation after the vehicle is started.

  Next, the processing procedure by the control means 3 will be described.

  The control means 3 takes in various information from a door switch, a seat belt connection switch, and the like, and performs a boarding determination process for determining whether or not the vehicle user has boarded the driver's seat of the vehicle (step S1). The boarding determination process can also be performed using the imaging information from the imaging means 2.

  When it is determined by the boarding determination process that the vehicle user has boarded, the control means 3 outputs a control signal to the display means 4 so as to display to prompt the operation of the operation means 1 (step S2). ). In this case, the control means 3 displays the start button of the vehicle on the display means 4 composed of a touch panel.

  Next, the control means 3 determines whether or not the operation means 1 corresponding to the display on the display means 1 has been operated (step S3). In this case, the control means 3 can determine the presence / absence of an operation by reading an operation signal generated when the start button of the display means 1 formed of a touch panel is touched.

  When it is determined that the operation unit 1 has been operated, the control unit 3 captures an image when the operation signal is received from among the imaging information captured by the imaging unit 2 of the vehicle user (identified person). A comparison process (comparison determination process) for comparing the captured image information with the identification information stored in the storage unit is performed (step S4). It is determined whether or not the user has information (step S5). Note that the control means 3 can also collate the image information captured before or after receiving the operation signal by performing pattern matching processing with the identification information. It is also possible to collate a plurality of pieces of imaging information imaged at a predetermined time (for example, 1 second) before and after receiving the operation signal.

  When it is determined by this determination that the identified person is a previously registered user, the control means 3 outputs a signal for permitting the vehicle to travel to the vehicle control device (step S6). In this case, a permission signal is output to an engine start control device serving as a drive source of the vehicle, and the start control device receives this signal and starts the engine.

  In addition, when it is determined by the determination process that the identified person is not a registered user, the control means 3 outputs a signal for prohibiting the vehicle to travel to the vehicle control device to indicate that it is not registered. It outputs to the display means 4 (step S6).

  Through the above-described processing of the vehicle personal authentication device, the vehicle user performs the collation processing together with the vehicle start operation without performing a special operation only for personal authentication.

  Such a vehicle personal authentication device is a vehicle personal authentication device that discriminates an identified person based on imaging information from the imaging means 2 provided in the vehicle, and is a position that can be operated by the identified person. The operation means 1 for generating an operation signal based on the operation provided on the camera, the imaging information from the imaging means 2 and the identification information stored in advance in the storage unit based on the timing when the operation signal from the operation means 1 is input. And a control means 3 for performing a comparison determination process.

  Accordingly, since the vehicle user can perform the matching process based on the imaging information captured in a state in which the line-of-sight direction is predicted to some extent without performing a troublesome operation only for personal authentication, it is easy and accurate. High verification processing can be performed. Further, since personal authentication can be performed with a small number of collation processes based on the timing at which the operation signal is input, no extra load is applied to the control means 3.

  Further, since the control means 3 outputs a signal based on the result of the comparison determination process to the vehicle control device, it is possible to perform the vehicle control process based on the personal authentication result such as engine start permission / prohibition. For example, when the identified person is not a registered user, the vehicle driving operation can be limited by performing vehicle control such as fixing the brake state, disabling the accelerator operation, and limiting the gear range.

  Further, the control means 3 uses the biometric feature without troublesome work by comparing and determining the iris of the identified person in the imaging information by performing pattern matching processing with the identification information. Thus, the vehicle personal authentication device can perform personal authentication.

  In addition, the control means 3 performs the comparison and determination process before the driving source of the vehicle is activated, so that the vibration of the imaging means 2 when the vehicle is traveling, frequent sight line movement and driving operation of the vehicle user. It is possible to capture the ecological characteristics of the identified person in a stable state while avoiding the state in which the user is performing.

  In addition, the operation unit 1 includes a touch panel and is provided in the vicinity of the imaging unit 2, thereby increasing the possibility that the identification subject's pupil can be accurately imaged during the operation. In addition, since it is possible to capture an image from the front side to some extent with respect to the line-of-sight direction, it is possible to obtain imaging information suitable for collation.

  In addition, although the driving | operation appropriateness determination system of this invention was mentioned as an example in the structure of embodiment mentioned above, this invention is not limited to this, The summary of this invention also in another structure It goes without saying that various improvements and design changes can be made without departing from the scope of the invention. For example, in the above-described embodiment, the image of the iris of the pupil is shown and collated, but the image of the fingertip fingerprint may be imaged and collated. In this case, before and after receiving the operation signal By collating the image information captured at the timing, the possibility of obtaining imaging information suitable for the collation is increased.

The figure which shows the structure of embodiment of this invention. The figure which shows the process sequence of the control means of embodiment same as the above.
