Abstract

Disclosed are a method and a device for operating an in-automobile device through an existing security system of an automobile. The device includes a controller that includes a CPU based control circuit connected to a radio frequency receiver circuit, a power supply and voltage regulation circuit, and a relay switching system. The controller is electrically connected to control circuits of in-automobile devices so that the controller can be controlled by a remote controller of the security system of the automobile to effect operation of the in-automobile device and to enhance functionality of the in-automobile devices and the security system of the automobile.

Claims

1. A method for operating an in-automobile device through an existing security system of an automobile, wherein a controller is provided and connected to the security system of the automobile, the controller being connected to the in-automobile device and being configured to detect activation/de-activation of security-related devices originally connected to and controlled by a security host device of the security system, and being further configured to receive a radio frequency transmitted from a remote controller of the security system;

and the remote controller of the security system being operated in a preset manner to transmit a preset radio frequency signal, which is received by a radio frequency receiver circuit of the controller to actuate a CPU based control circuit of the controller to detect the activation/de-activation of the security-related devices that are connected to and controlled by the security host device of the security system whereby when the activation/de-activation is confirmed, the CPU based control circuit generates a signal to set and/or release the in-automobile device connected thereto.

2. A device adapted to operate an in-automobile device through an existing security system of an automobile, comprising a controller that is connected to a security host device of the security system of the automobile and controllable by a remote controller of the security system of the automobile, the controller comprising:

a CPU based control circuit, which is configured to connect the in-automobile device and to detect activation/de-activation of security-related devices originally connected to and controlled by the security host device of the security system of the automobile;

a radio frequency receiver circuit, which is configured to receive a radio frequency transmitted from the remote controller of the security system of the automobile;

a power supply and voltage regulation system, which is connected to an ignition switch of the automobile; and

a relay switching system operable based on output of power supply.
