VEHICLE HIGH SECURITY PIGGYBACK MODULES
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 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 the 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 vehicle control system including:
-
a data communication bus at the vehicle;
a vehicle sensor;
a remote keyless entry (RKE) system comprising an RKE transmitter to be carried by a user, an RKE receiver at the vehicle, and RKE controller connected to said RKE receiver for generating RKE signals on said data communications bus responsive to said RKE transmitter, and at least one RKE actuator for performing and RKE function to the RKE signals; and
a piggyback controller at the vehicle and connected to said data communication bus for performing a desired piggyback control function based upon predetermine RKE signals generated on said data communication bus by said RKE controller. - View Dependent Claims (4)

5. 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 for 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;
enabling vehicle system actuation if the first and second actuation signals have been received within the predetermined period of time. - View Dependent Claims (6)

7. A vehicle control system including:
-
a piggy back module to provide (a) authentication 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 for actuation of any vehicle component.
