Abstract
Abstract The invention provides an ignition key-vehicle communication device having at least one electronic key which can be inserted into a vehicle-end ignition lock. A wireless key-vehicle communication component arranged on the key actuates at least one vehicle-end functional unit by activating an activation element which is arranged at the key end. To protect against incorrect operation, means are provided for detecting when a key is inserted into the ignition lock and/or is inserted in a specific position in the ignition lock, and disabling communication between this key and the functional unit to be actuated in response thereto. The means for protecting against incorrect operation are arranged on the key.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
138 words
Ignition key-vehicle communication arrangement for a vehicle having at least one remotely actuatable vehicle function, said arrangement comprising: at least one ignition key which can be inserted into an ignition lock in said vehicle; a communication component arranged on said ignition key for transmitting enabling data which actuate said at least one vehicle function; an activation element arranged on the ignition key for causing said communication component to transmit data which actuate said at least one vehicle function; and means for protecting against incorrect operation of said at least one vehicle function, said means comprising: means for detecting insertion of said ignition key into a position in said ignition lock; means responsive to a detection of said insertion of said ignition key, for disabling transmission of said enabling data by said communication component arranged on said ignition key.
Claim 2
Dependent Claim
138 words
Ignition key-vehicle communication arrangement for a vehicle having at least one remotely actuatable vehicle function, said arrangement comprising: at least one ignition key which can be inserted into an ignition lock in said vehicle; a communication component arranged on said ignition key for transmitting enabling data which actuate said at least one vehicle function; an activation element arranged on the ignition key for causing said communication component to transmit data which actuate said at least one vehicle function; and means for protecting against incorrect operation of said at least one vehicle function, said means comprising: means for detecting insertion of said ignition key into a position in said ignition lock; means responsive to a detection of said insertion of said ignition key, for disabling transmission of said enabling data by said communication component arranged on said ignition key.
Claim 3
Dependent Claim
43 words
Communication arrangement according to claim 1, wherein said position in said ignition lock comprises one of: presence of said ignition key in said ignition lock in any position therein; and orientation of said ignition key in a predetermined position in said ignition lock.
