Abstract

A remote transmitter for actuating a vehicle locking mechanism is provided with a power transfer contact. A docking port associated with the locking mechanism also has a contact for communicating with the locking mechanism. If the batteries associated with either the transmitter or the locking mechanism fail, then the transmitter may be inserted into the docking port. When inserted into the docking port, power and signals may be transferred over the contacts. Thus, if the battery associated with the remote transmitter fails, it can be powered by the locking mechanism battery. Conversely, should the locking mechanism battery fail, sufficient power can be supplied by the transmitter such that the lock can be unlocked. The system allows the elimination of the redundant mechanical lock typically associated with vehicles incorporating an electronic locking system. The mechanic locks have been provided redundantly to account for situations in which the battery has failed.

Description

AN ELECTRONIC TRANSMITTER KEY TO SUPPLY BACKUP POWER FOR AN ELECTRONIC LOCKING SYSTEM
BACKGROUND OF THE INVENTION This invention relates to a backup power arrangement for an electronic locking system of a vehicle that uses an electronic transmitter key for vehicle entry.
Modern vehicles are commonly provided with an electronic locking system that enables vehicle entry. Typically the electronic locking system uses a hand held remote control device that is operated by the driver and communicates electronically with a corresponding electronic locking mechanism generally positioned in the driver's side door. The hand held remote control device houses a battery and is normally used to remotely unlock the vehicle using an RF transmission. Hand held remote control devices are more convenient compared to the use of standard mechanical locking systems, which require key-to-door contact to operate. However, the reliability of the hand held remote control device used in a vehicle entry system is limited when compared with the reliability of standard mechanical lock systems due to the possibility of battery failure. Thus, the vehicles provided with electronic locking are also provided with a mechanical lock, which is redundant, to allow entry if the remote control or vehicle batteries die. There is a need for a means to provide suitable alternative backup power for an electronic locking system in order to increase the reliability of hand held remote control devices. It would be desirable to provide backup power not only as a means of remote communication for keyless entry, but also as a means for supplying backup power in the event that the vehicle battery fails. With such a system, the redundant mechanical lock can be eliminated.
SUMMARY OF THE INVENTION
In a disclosed embodiment of this invention, an alternative electronic locking system uses a modified hand held remote keyless entry transmitter device and docking port on the vehicle. The hand held remote keyless entry transmitter device will be referred to as a transmitter key. The transmitter key would normally be used to remotely unlock the vehicle using an RF transmission, just as with standard hand held RF remote control devices. The electronic locking system of the present invention uses a transmitter key that is electronically coded. With this invention, all transmitter keys are mechanically identical and are identified only by way of the electronic code. Another practical automotive application for the inventive electronic locking system using an electronically coded transmitter key would be for use as an ignition key.
The electric locking system further utilizes an electromechanical locking mechanism usually located in the vehicle's doors that is normally in the "locked" state. When an appropriately shaped transmitter key (as opposed to other foreign non-key objects) is inserted into a docking port on the electromechanical locking mechanism, a subsequent series of communication of electronic signals is triggered. An electronic security system reads the electronic code on the transmitter key. If the transmitter key is positively verified an electric actuator in the electromechanical locking mechamsm is energized momentarily, which allows the locking mechanism to unlock. In the unlocked state, the driver may gain vehicle entry. The mechanism remains in the unlocked state until the transmitter key is removed from the electromechanical locking mechanism, whereupon the system automatically mechanically resets to the locked state. The docking port need only be used on the driver's door, although electronic locks are preferably associated with the other doors. The transmitter key is capable of non-hard wired two way transmission with the electromechanical locking mechanism of the vehicle by way of RF transmitters/ receivers/antennas mounted in both the tip of the transmitter key and in the vehicle in the driver's side door. Further, there are power transfer contacts on both the transmitter key and the locking mechanism docking port. Thus, when the transmitter key is inserted into the docking port, power can be transmitted from the transmitter key to the locking mechanism, or in the opposed direction. Thus, in the event that the vehicle battery fails, it would be possible to insert the transmitter key into the locking mechanism in the vehicle door and transfer energy from the battery of the transmitter key to the vehicle. This energy would be used to operate the security system for positive verification of the electronic code carried by the transmitter key and to power the electric actuator in the locking mechanism and unlock the door. As a converse to this, if the battery in the hand held transmitter key fails, energy from the locking mechamsm of the vehicle could be transferred to the transmitter key which would power the transmitter key and allow for the electronic transmission of coded information back to the locking mechanism of the vehicle, thus enabling the electronic security system and the electric actuator to unlock the vehicle door. The reliability of the vehicle's electronics and the hand held transmitter key are normally limited by their respective batteries. A failure of either power source would cause a failure of the electronic locking system. The proposed solution allows the system to be operated in an emergency by either the vehicle's or the transmitter key's power source. This redundancy dramatically increases system reliability and eliminates any need for a redundant mechanical lock.
These and other features of the present invention can be understood from the following specification and drawings, the following of which is a brief description.
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view of the electronic vehicle locking system of the present invention in a remote configuration.
Figure 2 is a schematic view of the electronic vehicle locking system of the present invention that employs the backup power scheme.
DETAILED DESCRIPTION OF THE DRAWINGS
Figure 1 schematically shows the electronic vehicle locking system of the present invention generally at 10. Hand held transmitter key is generally indicated at 12. Transmitter key 12 includes key housing 14 which houses a power source in the form of battery 16 and extends into a tip 18. Tip 18 contains an RF transmitter/receiver/antenna 20 as well as an electronic contact 22. A switch 21, shown schematically, allows the operator to request a remote transmission of a door unlock request. Tip 18 is configured to be received by key socket or docking port 28 of corresponding electromechanical locking mechanism indicated at 30 and located in driver's side door 32. Electromechanical locking mechanism 30 is powered by battery 34. Electromechanical locking mechanism 30 communicates with an RF transmitter/receiver/antenna 36 as well as electronic security system 38, which may be the main vehicle computer, and which responds to electronic code from the transmitter key. At a point when security system 38 deems electronic code appropriate, electronic actuator 40 is energized thus allowing vehicle door lock 50 to unlock so that a driver may gain entry into the vehicle.
The docking port 28 further includes electronic contacts 39. The structure of the contacts 22 and 39 may be as known, such that they are capable of transmitting electric power of at least a limited voltage, and in addition transmitting codes under certain circumstances. This position is illustrated best in Figure 2.
The details of the electronic locking system may be as known, but are most preferably as disclosed in co-pending provisional patent application, Serial No. 60/166,395, entitled "Electronic Lock", and filed November 18, 1999. Moreover, the electronic contacts may be contacts which are brought into physical contact to transmit power and signals, or may be of the sort which transmit power and signals over a non-hardwired connection using the transmitter/receiver/antenna devices. A worker in the electronics arts would know how to provide such a function. Referring now to Figure 2, the electronic vehicle locking system is schematically shown generally at 10 in a configuration that employs the backup power scheme of the present invention. Tip 18 is configured to be fittingly received by docking port 28 of corresponding electromechanical locking mechanism 30 located in driver's side door 32. The RF transmitters/receivers/antennas 20 and 36 are highly coupled and designed to enable bi-directional energy transfer between the hand held transmitter key 12 and the electromechanical locking mechanism 30, respectively. In the event that vehicle battery 34 fails, transmitter key 12 is inserted into electromechanical locking mechanism 30 in the vehicle door 32. Energy from the transmitter key battery 16 is then transferred to the vehicle over contacts 22 and 39. This transferred energy operates electronic security system 38 for positive verification of the transmitter key electronic code and to power the electric actuator 40 to activate vehicle door lock 50.
Conversely, if transmitter key battery 16 fails, energy from the electromechanical locking mechanism 30 of the vehicle is transferred to transmitter key 12 between contacts 22 and 39. This energy powers the transmitter key 12 and allows for the electronic transmission of the electronic code back to electromechanical locking mechanism 30 thus enabling electronic security system 38 and electric actuator 40 to verify the key and unlock the vehicle door lock 50.
While the proposed invention has been disclosed powering a door lock, it should be understood that the invention can also be utilized to power other locks on the vehicle. As an example, the ignition lock may also be powered with this method. While standard batteries available today may have difficulty providing sufficient power for ignition, battery technology is improving greatly, and in the immediate future, sufficient strength batteries should be available to power the ignition through this method. A preferred embodiment of this invention has been disclosed, however, a worker in this art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied to determine the true scope and content of this invention.
