In order to construct the dual security key system for a vehicle of the present invention, the transponder 12 is detachably mounted to a key body 10 such as a smart key or a general starting key possessed by a driver.

As shown in FIG. 1, the transponder 12 is detachably mounted to the lower end of the key body 10 using a slide fastening structure, or a ball joint fastening interlocked with a button as shown in FIG. 2. It can be detachably mounted using the structure.

In this case, the transponder 12 is connected to the in-vehicle receiver 14 to enable wireless communication.

The receiver 14 is for receiving the authentication number signal of the transponder 12, and includes an antenna for easy reception of the authentication number signal, and as an example of application of the antenna, the antenna is mounted on the key bundle mounted in the door. The coil can be wound up and used.

The dual security key system for an automobile of the present invention, as shown in FIGS. 3 and 4, includes an engine controller that is communicatively connected to the receiver 12 in addition to the transponder 12 and the receiver 12. 16, the body controller 18 which is communicatively connected to the engine controller 16, and various lock devices 20, 22 in the vehicle which are in a state capable of being locked and unlocked by the control of the body controller 18; 24).

In this case, the in-vehicle locking device may include a glove box lock device 20, a console box lock device 22, and a trunk lid lock device 24 capable of storing various valuables.

The engine controller 16 receives the authentication number of the transponder 12 and the authentication number of the receiver 14 to perform the authentication procedure logic, and transmits the authentication result to the body controller 18, and is also in charge of the vehicle. When driving in the state, it performs engine fuel cut logic at a specific time.

The body controller 18 receives the authentication result from the engine controller 16, and when the authentication number of the transponder 12 and the authentication number of the receiver 14 coincide with each other, the in-vehicle locking devices 20, 22, and 24 ) Is controlled to be unlocked, and if the authentication number of the transponder 12 and the authentication number of the receiver 14 do not match or the authentication number signal of the transponder 12 is not received at all, the lock device in the vehicle It controls the (20, 22, 24) to the locked state.

Here, a method for controlling the dual security key system for a vehicle of the present invention based on the above configuration will be described.

When the transponder is fastened to the key body

The case where the transponder 12 is fastened to the key body 10 refers to a case in which the owner normally uses the vehicle without leaving the vehicle for a specific purpose (car wash, valet parking, maintenance, etc.).

When the owner approaches the vehicle with the key body to which the transponder is fastened, the authentication number signal of the transponder 12 mounted on the key body 10 is sent to the receiver 14 in the vehicle.

Next, the receiver 14 transmits the authentication number signal of the transponder 12 received from the transponder to the engine controller 16 together with the authentication number signal of the receiver 14 that the receiver 14 has. .

The engine controller 16 then determines whether the authentication number of the transponder 12 and the authentication number of the receiver 14 match.

As a result of the determination of the engine controller 16, when the authentication number of the transponder 12 and the authentication number of the receiver 14 match, the matching result signal is transmitted from the engine controller 16 to the body controller 18.

Accordingly, when the body controller 18 receives a result signal in which the authentication number of the transponder 12 and the authentication number of the receiver 14 coincide, the in-vehicle locking devices 20, 22, and 24 may be unlocked. The state is controlled.

That is, by operating the motor of the electric locking device applied to the lock device 20 of the glove box, the lock device 22 of the console box, and the lock device 24 of the trunk lid in the unlocking direction, the driver or Passengers will be able to open glove boxes, console boxes, and trunk lids.

If the transponder is removed from the key body

When the transponder 12 is detached from the key body 10, the borrower entrusts the vehicle and the key body for a specific purpose (car wash, valet parking, maintenance, etc.) and away from the vehicle with the transponder 12 carried. Say you are away.

If the vehicle owner moves away from the vehicle with the transponder 12 separated from the key body 10, the authentication number signal of the transponder 12 is not transmitted to the receiver 14 in the vehicle, and of course the engine controller. Also, 16 is in a state in which the authentication number signal of the transponder 12 cannot be received.

At this time, the authentication number signal of the other transponder other than the original transponder 12 may be transmitted to the engine controller 16 through the receiver 14.

Therefore, if the authentication number of the other transponder 12 and the authentication number of the receiver 14 do not match at the engine controller 16 or if the authentication number of the transponder 12 is not received, the result of the mismatching body is returned. To the controller 18.

Subsequently, all of the in-vehicle locking devices 20, 22, and 24 are controlled to a locked state by the control of the body controller 18 receiving the mismatch result signal.

That is, by operating the motor of the electric locking device applied to the lock device 20 of the glove box, the lock device 22 of the console box, and the lock device 24 of the trunk lid, the glove box, The console box, trunk lid, etc. cannot be opened to prevent theft of stored valuables.

Meanwhile, when the vehicle locking devices 20, 22, and 24 are all locked and controlled, the vehicle needs to be moved for a predetermined purpose (maintenance or car wash), and the engine is started using the key body. In order to prevent the vehicle from traveling beyond the driving distance (a distance required for moving the vehicle for maintenance or car wash), logic is performed.

That is, if the vehicle is driven while the engine is started as described above, the driving distance is accumulated, and the accumulated driving distance is subtracted from the driving limit distance pre-input in the engine controller, and the driving distance of the vehicle remains. The calculating step and the step of performing the fuel cut control for the engine in the engine controller 16 when the vehicle continues to travel and exceeds the driving range.

Therefore, when the entrusted vehicle travels more than necessary distance, the engine fuel cut is made automatically, and the vehicle is stopped, so that theft of the vehicle can be easily prevented.
