Description

The field relates to systems and devices for preventing theft of automobiles, and includes personal authentication items relating to permission / stop of operation functions of automobiles, sensors for biometric authentication used for the determination, and electronic systems that control the system. This is a field that requires both improved security and ease of operation for automobile security.

From a global perspective, the probability of a car being stolen is higher in foreign countries than in Japan. Accordingly, systems and devices as security for many automobiles have been developed and spread by foreign countries. In recent years, however, the increase in these crimes has become a problem in Japan. In particular, Japanese used cars are popular overseas, and their trading becomes a business, so stolen cars are becoming one of the supply sources, and people who are familiar with security systems find and prevent weaknesses in the system There is a strong tendency to break technology.

Worldwide, immobilizers (electronic movement lock devices) using IC technology are becoming popular. However, this method is effective for preventing duplication of keys, but the number of cases where it is broken is also increasing. As a further security improvement measure, many biometric authentication techniques such as fingerprints, irises and vein patterns have been proposed. As the background, the improvement in reliability in these biometric sensors and data processing has greatly contributed. (See Figure 3)

Looking at the following patent documents, there are simple systems such as Patent Documents 1, 7, 8, 9 and the like that enable engine start and steering lock release by personal authentication by biometric authentication. There has not been a policy in which the joint function part of the drive transmission part such as a shift lever or the braking function part of the drive transmission part as described is connected to biometric authentication.

In addition, there are many patents related to biometric authentication related to opening / closing of doors and starting / stopping of engines such as engines, such as Patent Documents 2, 3, 4, 6, 12 and the like. Security is low in a simple biometric authentication system, security is required only by combining systems that are not installed in multiple automobiles or additional devices such as IC cards, portable information devices, remote devices, and storage of inquiry information on server machines outside the vehicle. Many patents follow the idea that it will not improve.

As in the present invention, simple in-vehicle biometric authentication is applied mainly by permitting the joining function and the braking function of the drive transmission unit, and further hierarchically managed by opening / closing the door and starting / stopping the engine such as the engine. However, there are few inventions that secure security by eliminating complicated operations.

In order to ensure the security of recorded personal information to be inquired, Patent Documents 5, 8, 10, 11 and the like include measures such as data encryption and data deletion at the time of theft. In the present invention, as with biometric authentication, simple personal information data is erased and returned to the initial setting state, but in combination with some measures, total security is improved and operability is made easy. ing.
JP2003-182528 (Engine start permission by vein sensor authentication) Japanese Patent Laid-Open No. 2000-311220 (Biometric authentication is checked against the license IC card memory, and the operation of the vehicle is permitted with both information) Japanese Patent Laid-Open No. 2001-342760 (authentication based on fingerprints, but a system for permitting use by a combination of an IC card, fingerprint reading and a conventional key) JP-A-2005-36523 (system for performing biometric authentication via communication between a server, a portable terminal, etc.) JP-A-2006-514348 (shift lever is described as a target for preventing theft of automobiles, etc., but the system is a system by remote control against destruction of the lever, etc.) Japanese Patent Laid-Open No. 2000-85536 (Biometric authentication system from outside the car, but via a remote unit) JP 2002-47840 (Engine start permission system by biometric authentication) JP 2003-214241 (combination of engine start permission and biometric authentication and protection of stored information) JP2002-145019 (Fingerprint recognition system permitting steering and engine start) JP 2001-273498 (Personal authentication with biometric authentication data to be encrypted) Japanese Patent Laid-Open No. 2003-250181 (stolen vehicle security data is deleted remotely by recognition based on vehicle movement information) JP2009-12585 (Anti-theft device using portable device)

The following non-patent document states that an immobilizer (electronic movement lock device) has a great effect as an anti-theft vehicle. However, in Japan, there are still many thefts of cars with keys, and even immobilizers are not effective with keys. The Metropolitan Police Department has also appealed for raising awareness of crime prevention and theft risks. Leaving the car with the engine running is a high risk.
From the Metropolitan Police Department's website, “Don't be a victim of car theft and intent on the car” is summarized about the transition of damage and crime prevention measures. (As of July 1, 2009) From the Japan Automobile Manufacturers Association website, “No. 86 Measures against Stolen Vehicles” Here, the actual situation of the theft and the technical response status of the industry are reported. (As of July 1, 2009)

An object of the present invention is to greatly improve the level of a safety system of an automobile that employs a conventional key system for opening and closing a door and starting and stopping a prime mover such as an engine. The immobilizer system that exists as one of the candidates is not always effective because it is stolen with a key, especially in Japan, and it is inconvenient that it is difficult to make a duplicate of the key when used by multiple family members. End up. There is a need for an automobile security device that is at least as reliable as an immobilizer and that is easy to handle.

There are a number of cases in which the theft of an immobilizer system in a vehicle with a keyless theft cannot be ignored, and the stealing side is also technically up. In response to this problem, multiplexing of system devices is progressing in existing similar safety system devices, and the security is slightly improved, but the current situation is that the operation is troublesome. Therefore, aiming for further security, it aims to achieve both reliability and ease of operation. In particular, there is a need for a policy that firmly solves the problem of preventing vehicle theft that is unique to Japan.

Individual devices and systems are as simple as possible, aiming to achieve both cost and reliability, and as a total, the challenge is to incorporate technology that achieves both a high level of safety and improved driving operability.

In addition to the conventional car key system, the operation of the joint function part (8) or the braking function part (15) of the drive transmission part (10) connecting the prime mover such as the engine (5) and the tire rotating part (11) Alternatively, a system for improving safety for preventing car theft by means of biometric authentication such as fingerprint (2), iris (1), vein pattern, etc. to permit release is constructed. Thereby, even if the vehicle leaves in the idling state with a key, security for driving the vehicle can be maintained. Here, it is realized by introducing the driver's own personal authentication system, which is different from the application of the authentication permission system to the operation of the joint function part of the drive transmission unit and the authentication to the key.

In addition, the linkage with the idling stop system (see FIG. 5), together with the energy saving effect, has a great effect on theft when leaving with a key. At the same time, by coupling with the idling stop system, the engine start / stop and the security operation to actuate / release the joint function part (8) or brake function part (15) of the drive transmission part (10) are linked and operated. Simplification can be achieved. Here, the idling stop system is a mechanism that automatically performs idling stop when the vehicle is stopped, and aims to save fuel consumption. In other words, it is a system that detects the stop and stops the engine, detects the starting operation and restarts the engine (5). The specific operation procedure differs slightly depending on whether the vehicle is a manual vehicle, artistic vehicle, hybrid vehicle, or the like. (See Figure 5)

As an existing invention, biometric authentication for opening and closing the door (4) has been proposed in many cases, but in the present invention, it can be replaced with opening and closing with the key (3) from the viewpoint of opening from keylessness and annoyance. Biometric authentication is proposed.

Many devices using biometric authentication for engine start / stop have been proposed, but in the present invention, they are handled only as an auxiliary function. A subsystem device that permits the operation or release of the joint function part (8) or the brake function part (15) of the drive transmission part (10) that connects the engine and the motor rotating part with the tire rotating part, and a similar sub-system for engine start / stop Since the system devices are multiplexed, it is not always necessary to add complexity for improving security in individual subsystem devices.

In addition, biometric authentication registration information has many inventions that hate devices mounted on vehicles. In the examples so far, registration information is placed on a stationary server, on a mobile communication device (dedicated remote controller, mobile phone, etc.), or an IC card is separately made and placed on it. In these cases, it is necessary to maintain the server for security, and in addition to the key, a device for portable storage is added, and management of these devices is difficult. If these keys or portable devices are misplaced or stolen, there will be a fatal risk and they must be held with great care at all times. The possibility of being stolen if biometric information is placed on the vehicle (9) is a great risk. However, in the present invention, biometric authentication registration data is stored and authentication is performed. The biometric data is received and collated with the registration data (13), and only the encrypted data indicating the result is output, and the registration data is not output to the outside. If an abnormal operation is attempted to open or dismantle the case without biometric authentication, or to extract data from the circuitry of the electronic system, such abnormal operations such as not being registered will be detected. The apparatus has a function of automatically overwriting registration data (13) with irrelevant data and erasing biometric registration data. Furthermore, in a normal case, the electronic system is returned to an initial state where biometric authentication registration data is not yet registered, so that it is not necessary to install all control systems. At the same time, it is possible to lock the operation functions related to the driving of all automobiles. In addition, for the vehicle taken away due to theft in this way, the vehicle position tracking system that is completely independent of this device is identified and the vehicle (9) is recovered corresponding to the state. After that, it can be reset again and used.

Further, by installing the authentication system (12) on the vehicle, it is possible to register biometric authentication to a person who gives driving permission at the driving site of the car. However, as the authentication level, three ranks are set for the person, family, and friend, and particularly for a friend, authorization is given for a limited period. Of course, a full lock release mode for vehicle maintenance can also be prepared. At this time, at the time of maintenance, the authentication data (13) can be erased and cannot be read by anyone.

In the present invention, it is only necessary to hold the conventional key by taking advantage of the feature of biometric authentication, and even if the key is lost, it is possible to drive the car only by authentication with one's own biometric. In addition, even if another person tries to use the lost key, the vehicle cannot be driven without biometric authentication.

With regard to facilitating biometric authentication using fingerprints (2) or vein patterns in the passenger compartment, the driver in the driver's seat can use a specific depression (or protrusion) or finger Place your finger etc. on the surface shape that specifies the position, etc., hold the operation instrument with your hand so that measurement by the sensor (2) is possible, and measure the fingerprint or vein pattern, etc., if the original operation is natural, Alternatively, the authentication is completed without any special operation for biometric authentication by a method such as an iris that completes the authentication simply by directing the line of sight toward the sensor (1).

Drives the drive transmission unit (10) as a security system device for automobiles, compared to the conventional measures in which the key system is applied to the opening and closing of the door (4) and the engine (5) and (6) start / stop. Employs biometric authentication for transmission (8) and function stop by brake brake (15), adds a security subsystem device, and switches from key entry method to driver's personal authentication, with high security and key theft Has gained a crime prevention effect.

Leaving the engine while idling is a typical pattern of key theft, but it can be handled. In addition, it is said that it is more energy saving to stop the engine when idling when parked or stopped for more than 5 seconds. By automatically coupling the idling stop system and theft security, it is possible to suddenly leave the vehicle. Crime prevention and energy saving. (See Figure 5)

Biometric authentication for opening and closing the door is also provided, which is mainly aimed at dealing with the troublesomeness of key operations when getting on and off the car. Furthermore, by using biometric authentication relating to engine start / stop in combination, it is possible to drive the vehicle by keyless biometric authentication (1) and (2) alone. In addition, by being coupled to the idling stop system (see FIG. 5), it is possible to link the engine start / stop and the security operation to the constraint on the drive transmission system, thereby achieving easy operation.

The registration data for biometric authentication is in-vehicle, and backup, additional authentication, etc. can be easily performed on the vehicle. When the registration device itself is unlocked and dismantled, the registration data is automatically deleted, and the system returns to the initial setting state to cope with in-vehicle risk. Furthermore, the position of the stolen vehicle can be specified with respect to the stolen vehicle, and after the vehicle is collected, it can be reset and used again. As the authentication level, three ranks are set with the person, family, and friend, and particularly for a friend, authorization is given for a limited period. Of course, a full lock release mode for vehicle maintenance can also be prepared. At this time, at the time of maintenance, the authentication data can be erased and cannot be read by anyone.

In the present invention, it is only necessary to hold the conventional key by taking advantage of the feature of biometric authentication, and even if the key is lost, it is possible to drive the car only by authentication with one's own biometric. In addition, even if another person tries to use the lost key, the vehicle cannot be driven without biometric authentication.

For ease of biometric authentication using fingerprints or vein patterns in the passenger compartment, the driver in the driver's seat specifies a specific indentation (or protrusion) or finger position on the operating device such as the shift lever (7) or handle Place a finger etc. on the surface shape etc. (see Fig. 2), hold the operation instrument by hand so that measurement by the sensor is possible, measure the fingerprint and vein pattern etc. by allowing the original operation to be natural, Alternatively, the authentication is completed without a special operation for biometric authentication by a method such as an iris that completes the authentication simply by directing the line of sight toward the sensor (4). In particular, ergonomic studies have been conducted to reduce the authentication error rate so that authentication can be completed naturally in the driving operation of a conventional automobile without being conscious of biometric authentication by a sensor. (See Figure 3)

FIG. 1 shows a vehicle antitheft security device of the present invention. FIG. 2 depicts a flowchart of the functions of the security system of the present invention. FIG. 3 shows a comparison of the reliability of various biometric authentication systems. FIG. 4 shows a comparison between the current vehicle theft security device and the device of the present invention. FIG. 5 shows the operation procedure and contents of the idling stop system.

The biometric sensor is a sensor (2) (open / closed) that can be contacted from outside the vehicle by using a method (1) based on optical recognition from the inside of the glass to open and close the door, and in the surface of the vehicle body, door, etc It may be equipped with a cover that can be).

The biometric authentication sensor around the driver's seat places a finger or the like on a specific depression (or protrusion) of the operating instrument such as the shift lever (7) or the handle part, or a surface shape (2) that designates the position of the finger, etc. A method of measuring buttons such as fingerprints and vein patterns that can be easily reached by grasping an operation tool with a hand so that measurement by a sensor is possible, and that the original operation is natural. Etc. For biometric authentication using an iris or the like, a system is prepared in which authentication is completed simply by directing the line of sight toward the sensor (1). (See Figure 2)

In the biometric authentication, all the devices are mounted on the vehicle, and the driver's permission can be entirely authenticated on the vehicle. In order to preserve biometric registration data, all of the devices involved are built in a sturdy case, and the act of stealing registration data is prevented by overwriting the registration data with dummy data. Have a way to do it.

Furthermore, with regard to opening / closing of the door, engine start / stop, and operation / release of the joint function part (8) or the brake function part (15) of the drive transmission unit (10), the control of the electric signal for operation and the electric signal There are various settings for the operation of the actuator and the locking mechanism for the various levers that operate in response. At the same time, the above-described operation can be activated by a permission signal by biometric authentication, separately from the key system prepared from the original.

In setting up these security system devices to prevent vehicle theft, it is a premise to improve security by designing such as improving the rigidity of each hardware part of the automobile. In order to protect against attacks on the components and wiring related to the device of the present invention, the lock structure of the covers such as the bonnet, trunk room, and engine room where they are arranged is strengthened so that it can sufficiently withstand physical attacks. That is the premise. Similarly, in order not to easily allow entry into the vehicle interior, it is assumed that the door opening / closing lock structure is strengthened so that it can sufficiently withstand physical attacks. Furthermore, it is preferable that a method (such as a two-way key method) is set so that the key cannot be copied from the keyhole.

The system device of the present invention can coexist not only with the existing key system but also with various automobile security devices (vehicle tracking device, alarm system, etc.), and some systems and devices (idling stop system) Etc.) and each other. (See Figure 5)

FIG. 1 shows a vehicle antitheft security device of the present invention. The security barrier includes the door (3) opening and closing and the engine (5) starting / stopping by the conventional security key (3). The present invention is parallel to these functions, and the drive transmission unit ( 10) adopts biometric authentication (1) and (2) regarding function stoppage by drive transmission (8) and braking brake (15), adds security subsystem, and shifts from key entry method to personal authentication of driver By switching, it has a high security and a crime prevention effect against key theft. Also, for keyless systems, iris authentication (1), (14) for opening and closing the door (4), fingerprint authentication button for engine start / stop, or fingerprint authentication for the idle stop system ( 2) can be added.

FIG. 2 depicts a flowchart of the functions of the security system of the present invention. Although the basic configuration is the same as that shown in FIG. 1, it can coexist and cooperate with existing security products. Here, biometric authentication and registration can all be performed on the vehicle, and the registration data (13) and the electronic control board (12) are erased by overwriting the registration data when attacked so that they are not copied. Shall.

From a global perspective, the probability of a car being stolen is higher in foreign countries than in Japan. Therefore, many automobile security systems and devices have been developed and spread by foreign countries, and many companies sell automobile security products in this field. In order to cope with the increase in these crimes, automobile security products have become popular in the Japanese market. Equipment that has become a standard overseas is also available through a Japanese distributor. In recent years, Japanese-made security devices have been put on the market that surpass their overseas products.

However, in recent years, theft cases have increased in Japan and organized crime has increased, and there is a strong tendency for humans who are familiar with security systems to find weaknesses in the systems and devices and break prevention techniques. In addition, the number of cases in which an immobilizer (electronic movement lock device) using IC technology that has been established worldwide is also broken. Furthermore, in Japan, where the risk perception of vehicle theft is low, there are many key thefts, and there are no sufficient security devices. With some of these needs, dissatisfaction factors are increasing in the current higher-level model, and the demand for further security reliability will become stronger. At the same time, the ease of operation is becoming an important factor as a product for the current complicated handling.

As a further security improvement measure, a number of biometric authentication techniques such as fingerprints, irises, and vein patterns have been proposed as trends in patents. As the background, the improvement in the reliability of these biometric sensors and data processing has greatly contributed, and the time has come to actually appear on the market. (See Figure 3)

The present invention has a strong potential as a device that satisfies these security reliability, response to key theft specific to Japan, simplification of operability, and the like.
