Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
It will be apparent to those skilled in the art that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. Like reference numerals refer to like elements throughout.
FIG. 1 is a conceptual diagram of a vehicle safety smart key system according to the present invention, and FIG. 2 is a schematic plan view of a vehicle safety smart key according to the present invention.
The vehicle safety smart key system according to the present invention includes a vehicle safety smart key 100 and a vehicle control 200 for receiving signals from the vehicle safety smart key 100, as shown in FIG.
The vehicle safety smart key 100 is for preventing start-up of a vehicle and theft of the vehicle and preventing drunken driving of a quasi-user (driver), and includes a sensor module 120, a memory module 140, a smart key communication module 180, and a smart key control module 160.
The sensor module 120 senses the human body information of the user. To this end, the sensor module 120 includes a fingerprint recognition sensor 122, an illuminance sensor 124, a temperature measurement sensor 126, and an alcohol measurement sensor 128.
The fingerprint recognition sensor 122 is used to prevent a vehicle from being stolen. The present invention recognizes the fingerprint of the user through the fingerprint recognition sensor 122 and allows the vehicle door to be opened and closed only in the stored fingerprint, (100) Prevents vehicle theft when lost. In order to perform such a function, the fingerprint recognition sensor 122 may be a fingerprint sensor that displays an inherent characteristic difference in each user, such as a semiconductor device type that senses optical, electrostatic capacitance, or electric conduction, a heat sensing method, A feature extraction module for extracting the feature information of the acquired original fingerprint image, a fingerprint feature information storage part for storing the fingerprint feature information of the user stored in advance in the fingerprint feature database 142 of the memory module 140, The fingerprint of the user can be recognized by comparison and matching.
The illuminance sensor 124 discriminates whether the user recognizes the fingerprint through the fingerprint recognition sensor 122 during the day or at night. This can be performed by comparing the roughness value stored in the roughness database 148 to be described later with the roughness value obtained by the roughness sensor 124. The present invention is intended to measure drinking by determining whether the user recognizes fingerprints during the day or night, taking into consideration that the drinking is mainly performed at night. Accordingly, when the user recognizes the fingerprint is low, the body temperature measuring sensor 126 and the alcohol measuring sensor 128, which will be described later, do not operate. At night, the body temperature measuring sensor 126 and the alcohol measuring sensor 128 Thereby determining whether or not the user is drinking. The illuminance sensor 124 is provided to sense illumination in the vehicle safety smart key 100. Of course, the present invention may omit the illuminance sensor 124 and discriminate whether or not the user is drinking through the always-on temperature measurement sensor 126 and the alcohol measurement sensor 128.
Further, the present invention may distinguish whether the time when the user recognizes the fingerprint through the fingerprint recognition sensor 122 at the current time in place of the illuminance sensor 124 or the above-described illuminance sensor 124 is day or night. To this end, the present invention may include a time measurement module.
The time measurement module may be implemented via a clock module embedded in the form of an IC in the vehicle safety smart key 100. In addition, the time measurement module can communicate with the vehicle through the smart key communication module 180, which will be described later, for time accuracy, to synchronize the correct time periodically or intermittently. However, the present invention is not limited thereto, and the time measurement module may check the time taken for fingerprint recognition by performing communication with the vehicle when the user recognizes the fingerprint through the fingerprint recognition sensor 122 instead of the clock module . This can be accomplished by acquiring time information by a GPS (Global Positioning System) of the vehicle.
The body temperature measuring sensor 126 measures the body temperature of the user when the time at which the user recognizes the fingerprint is low in the time measurement module. This changes the body temperature according to the reaction of the body when drinking, and judges the change of body temperature to determine whether or not to drink. Accordingly, the memory module 140, which will be described later, is provided with a reference body temperature database 144 that can be compared with the body temperature of the user measured by the body temperature measurement sensor 126. In addition, the body temperature of the user measured by the body temperature measuring sensor 126 is transmitted to the smart key control module 160, which will be described later.
On the other hand, it is effective that the measurement of the user's body temperature of the body temperature measurement sensor 126 is performed together with the user fingerprint recognition in the fingerprint recognition sensor 122. For this, the fingerprint recognition sensor 122 and the body temperature measurement sensor 126 are preferably integrated. That is, when the user recognizes the fingerprint, it is preferable that the user's body temperature is measured through the user's finger at the same time as the fingerprint recognition.
The alcohol measurement sensor 128 measures the alcohol concentration in the user's breath when the body temperature measured by the body temperature measurement sensor 126 is abnormal. The alcohol measurement sensor 128 is exposed in the vehicle safety smart key 100 according to the present invention and can measure the alcohol concentration through the user's exhalation. In addition, the measured alcohol concentration of the user is transmitted to the smart key control module 160, which will be described later.
The memory module 140 stores a database required for the fingerprint recognition sensor 122, the body temperature measurement sensor 126 and the alcohol measurement sensor 128. The database includes a fingerprint feature database 142 A reference body temperature database 144 in which general body temperature information that is not a drinking state is stored, an alcohol concentration database 146 in which alcohol concentration information corresponding to a drinking operation is stored, and an illuminance database 148 ).
The smart key control module 160 controls the sensor module 120, the memory module 140, and the smart key communication module 180. In the present invention, a machine control unit (MCU) is used as the smart key control module 160. The smart key control module 160 controls the sensor control modules 162, 164 and 166 and the memory control module 160, And a communication control module.
The sensor control modules 162, 164 and 166 are for effectively controlling the sensor module 120 described above and include a fingerprint sensor control module 162, a time measurement control module, a temperature measurement sensor control module 164, And a measurement sensor control module 166.
The fingerprint recognition sensor control module 162 controls the fingerprint recognition sensor 122. That is, when the user recognizes his / her fingerprint on the fingerprint recognition sensor 122, the fingerprint recognition sensor control module 162 determines whether the user is a registered user and releases the locking device of the vehicle door. To this end, the fingerprint recognition sensor control module 162 includes a user fingerprint registration module, a user fingerprint recognition module, and a vehicle unlocking module.
The user fingerprint registration module registers the fingerprint of the first user. To this end, the user fingerprint registration module includes a fingerprint registration module, a fingerprint deletion module, and a vehicle start confirmation module. That is, the user fingerprint registration module activates the fingerprint registration module and the fingerprint deletion module only when the vehicle is started through the vehicle start confirmation module. With this structure, the user activates the fingerprint registration module through the fingerprint registration button while the vehicle is running, and registers the fingerprint by recognizing his / her fingerprint on the fingerprint recognition sensor 122. Of course, the recognized fingerprint is stored in the fingerprint characteristic database 142. [ In addition, the recognized fingerprint may be stored in the vehicle control unit 200 as well as the vehicle safety smart key 100. [ In this case, it is possible to prevent the start of the vehicle as well as the unlocking of the vehicle, even if the fingerprint feature database stored in either one, particularly the vehicle safety smart key 100, is manipulated. In addition, a fingerprint of a plurality of users may be registered in one vehicle safety smart key 100, and the fingerprint deletion module may include a display for selecting and deleting fingerprints of various users. Meanwhile, in order to improve the fingerprint recognition performance of the user, the fingerprint recognition is performed by recognizing the fingerprints many times rather than registering the fingerprints one time, and then matching the fingerprints recognized by the user .
The user fingerprint recognition module recognizes the user fingerprint acquired through the fingerprint recognition sensor 122 after registering the user fingerprint through the user fingerprint registration module. This can be performed by extracting the fingerprint feature information from the user fingerprint information obtained by the fingerprint recognition sensor 122 and comparing the fingerprint feature information with the fingerprint feature information stored in the fingerprint feature database 142. [
The vehicle lock releasing module releases the lock of the vehicle door when it is confirmed that the fingerprint of the user is recognized through the user fingerprint recognition module and matches with the fingerprint feature information of the user stored in the fingerprint feature database 142. [ Further, in order to unlock the door of the vehicle, the vehicle unlocking module causes the vehicle control unit 200 to transmit the vehicle unlocking signal via the smart key communication module 180. [
The time measurement control module determines the time when the user fingerprint is confirmed through the user fingerprint recognition module and determines whether the body temperature sensor control module 164 to be described later operates. That is, as described above, the time measurement control module prevents the temperature measurement sensor control module 164 and the alcohol measurement sensor control module 166, which will be described later, from operating when the user recognizes the fingerprint is low. When the user recognizes the fingerprint at night, the body temperature sensor control module 164 to be described later operates.
The body temperature sensor control module 164 operates under the control of the time measurement control module and activates the operation of the body temperature measurement module described above so as to measure the body temperature of the user. When the user's body temperature is measured by the body temperature measurement module, the measured user body temperature is compared with the reference body temperature database 144 to determine whether the alcohol measurement sensor control module 166 to be described later operates. That is, when the measured user's body temperature is different from the temperature stored in the reference body temperature database 144, for example, if the measured user's body temperature is high, the body temperature measurement sensor control module 164 determines that the user's body temperature has risen due to drinking, The alcohol measurement sensor control module 166 is activated. Of course, if it is determined that the user does not drink alcohol, the body temperature sensor control module 164 transmits a vehicle start signal to the vehicle controller 200 through the smart key communication module 180 so that the user can start the vehicle State.
The alcohol measurement sensor control module 166 operates under the control of the body temperature measurement sensor control module 164 and activates the operation of the alcohol measurement sensor 128 so as to finally determine whether or not the user is drinking. When the alcohol concentration in the user's breath is measured by the alcohol measurement sensor 128 and the measured alcohol concentration of the user is compared with the alcohol concentration database 146 and the measured alcohol concentration of the user is higher than the reference, Is in the drinking state. For example, if the measured alcohol concentration of the user is 0.05% or more, it can be determined that the user is in the drinking state. Accordingly, the alcohol measurement sensor control module 166 transmits the vehicle operation restriction signal to the vehicle through the smart key communication module 180 to prevent the vehicle from being started. Of course, if it is determined that the user does not drink alcohol, the alcohol measurement sensor control module 166 transmits a vehicle start signal to the vehicle controller 200 so that the user can start the vehicle.
The vehicle control unit 200 is for controlling the vehicle by communicating with the vehicle safety smart key 100. The vehicle control module 200 includes a vehicle communication module 220 for performing communication with the vehicle safety smart key 100, And a vehicle control module 240 for controlling the vehicle by processing signals of the vehicle safety smart key 100 received through the vehicle safety smart key 100.
The vehicle communication module 220 communicates with the smart key communication module 180 of the vehicle safety smart key 100.
The vehicle control module 240 controls the vehicle in accordance with the control signal of the vehicle safety smart key 100 received via the vehicle communication module 220. [ The vehicle control module 240 includes a vehicle lock control module 242 and a vehicle start control module 244. [
The vehicle lock control module 242 releases the lock of the vehicle when the user recognizes his / her fingerprint to the fingerprint recognition sensor 122. [ When the user recognizes his / her fingerprint in the fingerprint recognition sensor 122, the fingerprint recognition sensor control module 162 extracts the fingerprint feature information from the recognized fingerprint and compares the fingerprint feature information with the fingerprint feature information in the fingerprint feature database 142 And may be performed by a vehicle unlock signal transmitted to the vehicle communication module 220 when it is matched.
The vehicle start control module 244 determines that the user has not drunk through the body temperature measurement or the body temperature measurement and the alcohol measurement so that the user can start the vehicle by the vehicle start signal transmitted to the vehicle communication module 220 And controls the vehicle in a state where it is in the state.
3 is a conceptual diagram of a vehicle safety smart key system according to another embodiment of the present invention.
In the above-described embodiment, the memory module is provided in the vehicle safety smart key, but the present invention is not limited thereto. That is, the memory module 140 described above may be provided in the vehicle controller 200. In this case, the user fingerprint, body temperature, alcohol concentration and illuminance obtained from the vehicle safety smart key 100 are transmitted to the vehicle control unit 200 and stored in the memory 260 of the vehicle control unit 200, , The reference body temperature database 264, the alcohol concentration database 266, and the illuminance database 268, respectively, to control the vehicle in a state in which the vehicle can be unlocked and the vehicle can be started.
As described above, the present invention can provide a vehicle safety smart key system capable of unlocking a vehicle by a user's fingerprint. In addition, the present invention can provide a vehicle safety smart key system capable of discriminating whether or not to drink by measuring the temperature of a user in the night when the night and day are distinguished, and controlling the start of the vehicle. Further, the present invention can provide a vehicle safety smart key system capable of more reliably discriminating whether or not alcohol is being consumed by measuring the alcohol concentration with respect to an abnormal body temperature, and controlling the starting of the vehicle.
