Abstract
Abstract A keyless entry system, is associated with a steering lock device. The steering lock device includes an electrically operated actuator (302) for operating the steering lock device between locking and unlocking positions. Steering locking and unlocking operation is triggered by a predetermined vehicle operation, such as closing of the vehicular doors. A predetermined steering lock condition is checked as triggered the steering locking and unlocking operation. Steering locking and unlocking operation is carried out when the operation is triggered and the steering lock condition is satisfied.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
244 words
A keyless entry system for an automotive vehicle for operating various vehicle devices including a door lock and a steering lock, comprising: 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 for operating the latter to desired (302 a) state, said actuator including a steering lock actuator associated with said steering lock for operating the latter between a locking state and an unlocking state; manual switches (202) each adapted to trigger a controller (200) for signalling said keyless entry system to operate a corresponding one of said vehicle devices; a first detector (229) for detecting door close position for outputting a first detector signal; a second detector (215) adapted to detect a predetermined steering lock condition to output a second detector signal when said steering lock condition is detected; and (200) a controller/mounted on the vehicle and adapted to transmit a demand signal for triggering said transmitter (100) and receiving said unique code indicative transmitter (100) and receiving said unique code indicative signal, comparing the received unique code with a second preset code, and producing a control signal a control signal only when the received unique code matches said second preset code, said controller is responsive to said first and second detector signal to transmit said control signal to said steering lock actuator (302a) for performing steering locking and unlocking operation.
Claim 2
Dependent Claim
244 words
A keyless entry system for an automotive vehicle for operating various vehicle devices including a door lock and a steering lock, comprising: 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 for operating the latter to desired (302 a) state, said actuator including a steering lock actuator associated with said steering lock for operating the latter between a locking state and an unlocking state; manual switches (202) each adapted to trigger a controller (200) for signalling said keyless entry system to operate a corresponding one of said vehicle devices; a first detector (229) for detecting door close position for outputting a first detector signal; a second detector (215) adapted to detect a predetermined steering lock condition to output a second detector signal when said steering lock condition is detected; and (200) a controller/mounted on the vehicle and adapted to transmit a demand signal for triggering said transmitter (100) and receiving said unique code indicative transmitter (100) and receiving said unique code indicative signal, comparing the received unique code with a second preset code, and producing a control signal a control signal only when the received unique code matches said second preset code, said controller is responsive to said first and second detector signal to transmit said control signal to said steering lock actuator (302a) for performing steering locking and unlocking operation.
Claim 3
Dependent Claim
32 words
The keyless entry system as set forth in claim 2, wherein said second detector (215) is detective of an engine stopping and produces said second detector signal when engine stopping is detected.
Claim 4
Dependent Claim
34 words
The keyless entry system as set forth in claim 1, wherein said second detector (215) is detective of a vehicle stopping and produces said second detector signal whe the vehicle stopping state is detected.
Claim 5
Dependent Claim
41 words
The keyless- entry system as set forth in claim 1, wherein said second detector 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 6
Dependent Claim
60 words
The keyless entry system as set forth in claim 1, wherein said controller (200) as triggered for performing steering locking and unlocking operation, transmits a demand signal to said transmitter 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.
