Vehicle use lock system

Claim 1

An enabling lock system for a vehicle, said enabling lock system comprising: a main vehicle controller, a card style external controller in communication with said main vehicle controller through wireless signals, vehicle lock means operatively connected to said main vehicle controller for securing the vehicle, said vehicle lock control means including a door lock controller and a steering controller, and a source of electrical power connected to said door lock controller and said steering controller, an ignition key operated steering lock assembly having a steering lock controller with a manually operating assist knob arm and an engine ignition switch, each of said steering lock controller and said engine ignition switch being connected to said source of electrical power and said main vehicle controller, a hidden steering lock switch being positioned near said knob arm and connected to said source of electrical power and said main controller, a door handle switch connected to said main controller and having the positions of on or off when the door handle is either opened or closed, respectively electrical conductor means for establishing two-way communication between said main vehicle controller and said steering lock controller, said two-way communication being established from said door lock controller, actuator means engageable with said steering lock controller for enabling and disabling thereof; housing means for enclosing said actuator means in common with said key operated steering lock assembly and said steering lock controller in rigidly fixed relation to each other, said actuator means being electrically connected to said power source through said steering lock controller upstream thereof to prevent release of said steering lock controller in response to disconnection of said power source therefrom so that even if unauthorized persons should break intermediate leads from said power source upstream of said steering lock controller and connect thereto a new power source or reconnect said power source directly thereto, said actuator means cannot be energized and actuated, an antenna group serving for establishment of said two-way communication between said card style external controller and said main vehicle controller, said antenna group comprising at least three antenna elements, each being positioned at remote and hidden locations in the vehicle such that said antenna elements are in close proximity of a side mirror of the vehicle, an assistant driver's seat and within trunk space thereof, and each said antenna element being connected to said main vehicle controller, said steering lock controller including a pair of relay devices connected to said actuator means for respectively enabling and disabling said key operated steering lock assembly, a first coded signal being transmitted by said card style external controller, said first coded signal being in the form of a pulse pattern signal, a second code signal being specifically selected and permanently preset in said main vehicle controller, and a coincidence signal discriminator means for determining when there is a coincidence between said first and second coded signal during actuation of said key operated steering lock assembly.
