Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
333 words
A keyless entry system for an automotive vehicle for operating various vehicle devices including a door lock, a steering lock and manual switches, characterized by: a portable wireless transmitter (100) adapted to transmit a unique code indicative signal encoded to carry a preset unique code stored in said transmitter; actuators (302), each associated with corresponding vehicle devices (300) for operating the latter to a desired state, said actuators including a steering lock actuator (302a) associated with said steering lock for operating the latter between a locking state and an unlocking state; a controller (216) triggered by said manual switches (202) for signalling said keyless entry system to operate a corresponding one of said vehicle devices (300); a first detector (229) for detecting the door close position for outputting a first detector signal; a detector (215c) adapted to detect a predetermined steering lock condition and outputting a second detector signal when said steering lock condition is detected; a detector (236) for detecting whether said door lock is locked; a controller (200) mounted on the vehicle and adapted to transmit a demand signal for triggering said transmitter (100) and receiving said unique code indicative signal, comparing the received unique code with a second preset code, and producing a control signal to operate at least one of said actuators (302) only when the received unique code matches said second preset code, said controller (200) being responsive to said first and second detector signals for transmitting said control signal to said steering lock actuator (302a) for performing steering locking and unlocking operation; and a disabling'means (282) which becomes active when the vehicle door is closed and the door lock (300-D) is locked, and responding, when activated, to said unique code-indicative signal for a period of time longer than a predetermined period of time to disable the operation of said controller, said disabling means (282) detecting the presence of a user in the vehicle and remaining inactive when the presence of a user in the vehicle is detected.
Claim 2
Dependent Claim
333 words
A keyless entry system for an automotive vehicle for operating various vehicle devices including a door lock, a steering lock and manual switches, characterized by: a portable wireless transmitter (100) adapted to transmit a unique code indicative signal encoded to carry a preset unique code stored in said transmitter; actuators (302), each associated with corresponding vehicle devices (300) for operating the latter to a desired state, said actuators including a steering lock actuator (302a) associated with said steering lock for operating the latter between a locking state and an unlocking state; a controller (216) triggered by said manual switches (202) for signalling said keyless entry system to operate a corresponding one of said vehicle devices (300); a first detector (229) for detecting the door close position for outputting a first detector signal; a detector (215c) adapted to detect a predetermined steering lock condition and outputting a second detector signal when said steering lock condition is detected; a detector (236) for detecting whether said door lock is locked; a controller (200) mounted on the vehicle and adapted to transmit a demand signal for triggering said transmitter (100) and receiving said unique code indicative signal, comparing the received unique code with a second preset code, and producing a control signal to operate at least one of said actuators (302) only when the received unique code matches said second preset code, said controller (200) being responsive to said first and second detector signals for transmitting said control signal to said steering lock actuator (302a) for performing steering locking and unlocking operation; and a disabling'means (282) which becomes active when the vehicle door is closed and the door lock (300-D) is locked, and responding, when activated, to said unique code-indicative signal for a period of time longer than a predetermined period of time to disable the operation of said controller, said disabling means (282) detecting the presence of a user in the vehicle and remaining inactive when the presence of a user in the vehicle is detected.
Claim 3
Dependent Claim
36 words
The keyless entry system as set forth in claim 1, which further comprises a manual operation mechanism associated with said door lock (300-D) for allowing manual operation of said door lock between locking and unlocking states.
Claim 4
Dependent Claim
27 words
The keyless entry system as set forth in claim 2, which further comprises a detector detecting manual operation of said manual operation mechanism to the locking position.
Claim 5
Dependent Claim
56 words
The keyless entry system as set forth in claim 1, wherein said disabling means (282) produces an alarm after expiration of a first given period of time following production of said code-indicative radio in response to said second demand signal and then produces said disabling signal after expiration of a second given period of time thereafter.
Claim 6
Dependent Claim
27 words
The keyless entry system as set forth in claim 4, wherein said second given period of time is substantially longer than said first given period of time.
Claim 7
Dependent Claim
45 words
The keyless entry system as set forth in claim 5, wherein the difference between said first and second given periods of time is long enough to allow the user to operate said manual switches (202) again and to remove said transmitter (100) from the vehicle.
Claim 8
Dependent Claim
68 words
The keyless entry system as set forth in claim 1, which further comprises an ignition key detector which produces a signal indicative of the presence of an ignition key in a key cylinder when said ignition key is in said ignition key cylinder, and wherein when the vehicle doors are closed and locked, said controller (200) is responsive to said key-indicative signal to disable said disabling means (282).
Claim 9
Dependent Claim
67 words
The keyless entry system as set forth in claim 1, which further comprises an ignition key detector which produces a signal indicative of the presence of an ignition key in a key cylinder when said ignition key is in said ignition key cylinder, and wherein said controller (200) is responsive to said key-indicative signal and operation of said manual switches (202) to disable the keyless entry system.
Claim 10
Dependent Claim
37 words
The keyless entry system as set forth in any one of claims 1 to 8, wherein said second detector (215b) is detective of an engine stopping and produces said second detector signal when engine stopping is detected.
Claim 11
Dependent Claim
39 words
The keyless entry system as set forth in any one of claims 1 to 8, wherein said second detector (215a) is detective of a vehicle stopping and produces said second detector signal when the vehicle stopping state is detected.
Claim 12
Dependent Claim
47 words
The keyless entry system as set forth in any one of claims 1 to 8, wherein said second detector (215) is detective of an engine stopping and a vehicle stopping and produces said second detector signal when the engine stopping and the vehicle stopping are both detected.
Claim 13
Dependent Claim
66 words
The keyless entry system as set forth in any one of claims 1 to 8, wherein said controller (200) is triggered for performing steering locking and unlocking operation, transmits a demand signal to said transmitter (100) and compares the unique code transmitted from said transmitter with said preset code for enabling said steering locking and unlocking operation only when said unique code matches said preset code.
