First Claim
Patent Images
1. A vehicle high security piggyback module system adapted to be used in conjunction with a double locking latch system for a vehicle, said module system including:
- an electrical wiring harness loom;
an information link to carry encrypted actuation signals and conventional electrical actuation signals;
processing software to detect a first encrypted signal and a second conventional signal, and to determine whether or not the first and second signals have been detected within a predetermined period of time; and
authorizing software to permit further activation only if the first and the second signals have been detected within the predetermined period of time.

3. A method of controlling actuation of vehicle control systems including the steps of:
-
generating a first encrypted actuating signal for denoting actuation of a vehicle system; generating a second conventional actuating signal denoting actuation of a vehicle system; establishing a predetermined time period during which receipt of the first and second actuating signals is to occur; sensing a predetermined time period between actuating signals; and enabling vehicle system actuation if the first and second actuation signals have been received within the predetermined period of time. - View Dependent Claims (4)

5. A vehicle control system including:
-
a piggyback module to provide (a) authentication of an actuation of an actuation signal and (b) authentication of a vehicle component identification in order to provide control of vehicle systems; a standard wire harness to provide an activating power to an electronic actuator (window motor, latch motor etc.); and an encryption module for generating an encrypted control area network (CAN) signal to provide a double check function of actuation of any vehicle component.
