Abstract
An anti-theft vehicle subsystem disabling device including a digital controller and one or more remote receiving vehicle subsystem interface units for randomly simulating problematic vehicle behavior. The system determines user authorization based on keycode entry of either a master code or a programmable user code. Once authorized all vehicle subsystems under control operate normally. While authorized, the system also allows optional entry into a valet mode and constantly monitors a hidden anti-hijacking button. Any time unauthorized use is determined, the digital controller randomly generates a unique controlling signal with random timing variations that is communicated to the remote receiving subsystem interface units. These units can be connected in series with vital vehicle subsystem components in order to interfere with typical subsystem component operation, thereby inducing the illusion of an actual vehicle problem severe enough to inhibit vehicle driveability. This system allows unique implementation by locating disabling receivers on any variety of vital vehicle subsystems, presenting thieves with multiple unknowns specific to each vehicle. Due to this, in addition to the random nature of the device, there is no chance for a pattern to develop, and therefore very little possibility that the device will be recognized by an unauthorized operator.
