    • A theft preventive system, in an automotive keyless entry system with automatic door locking, is adapted to produce an alarm signal in response to door opening when the theft preventive system is in a door-locked position, and which is cooperative with a door-lock system but independently operable in order to switch its operating mode from a door-locked mode to a door-unlocked mode. The theft preventive system in an automotive keyless entry system, according to the present invention, includes a push-button-type function key for operating a door-lock mechanism to lock a vehicle door. A memory circuit is responsive to a door-lock signal fed from the door-lock function key to indicate the door-locked condition. The content of the memory cannot be cleared unless a plurality of door-unlock function keys are properly operated. An alarm circuit is responsive to a door-open signal from a door switch in the presence of a memory output indicative of the door-locked condition to produce an alarm signal.
    • 在具有自动门锁的汽车无钥匙进入系统中的防盗系统适于当防盗系统处于门锁位置时响应于门打开产生报警信号,并且与门锁配合 系统,但是可独立操作以将其操作模式从门锁模式切换到门解锁模式。 根据本发明的汽车无钥匙进入系统中的防盗系统包括用于操作门锁机构以锁定车门的按钮式功能键。 存储电路响应于从门锁功能键输入的门锁信号来指示门锁状态。 除非正确地操作多个门解锁功能键,否则不能清除存储器的内容。 在存在指示门锁状态的存储器输出的情况下,报警电路响应来自门开关的门打开信号以产生报警信号。

    • A door lock security system is disclosed in which each lock in a multiple lock system is modified by the addition of door lock security apparatus which, in electrical form, stores at least an individual key combination (and possibly several different levels of master key combinations) for the lock. Also, the conventional lock cylinder is replaced with a cylinder assembly which senses the magnetic reluctance state (high or low) of predetermined locations on a key substantially resembling a conventional cylinder lock key in size, weight and general shape and capable of mechanically operating the lock. The magnetic reluctance states of the predetermined locations digitally encode the key combination and the thus encoded combination is compared to the electrically stored one, disabling the mechanical operation of the lock unless the two combinations are identical. The electrical combination storage means within the door lock security apparatus may be placed in an adaptive state in which the combination of the next key inserted into the lock is stored as the lock combination and, thereafter, only a key with that combination will operate the lock. There is also provided an emergency key which overrides all other keys and, at any time, can operate any lock in a multiple lock system. This emergency key generates a time varying electrical signal which enables operation of any door lock despite its stored combination.
    • 公开了一种门锁安全系统,其中通过添加门锁安全装置来修改多锁系统中的每个锁,电门形式存储至少一个单独的密钥组合(并且可能存储几个不同级别的主密钥组合) 为锁。 此外,传统的锁芯被替换为气缸组件,该气缸组件在大小,重量和大体形状上基本上类似于常规气缸锁定键的键上感测预定位置的磁阻状态(高或低),并且能够机械地操作锁 。 预定位置的磁阻状态对密钥组合进行数字编码,并将这样编码的组合与电存储的组合进行比较,禁止锁的机械操作,除非两个组合相同。 门锁安全装置内的电气组合存储装置可以被放置在自适应状态,其中插入到锁中的下一个键的组合被存储为锁组合,然后只有具有该组合的键将操作锁 。 还提供了一个覆盖所有其他键的紧急钥匙,并且可以随时操作多锁系统中的任何锁。 该紧急钥匙产生时变电信号,即使存储组合也能够操作任何门锁。
