If the identifying informations do not coincide with each other in at least one of the immobilizer controller and the shift controller, neither a fuel-injection-control permitting command nor a shift-lock-cancellation permitting command is output. An engine is maintained in its inoperative state, and a transmission is maintained in a state where rotation of a driving-torque transmitting shaft is prevented. If the identifying informations coincide with each other in the immobilizer controller, it is possible to reinforce security in comparison with the case where the fuel-injection-control permitting command and the shift-lock-cancellation permitting command are output.Type: GrantFiled: December 27, 2000Date of Patent: November 9, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventor: Akihiro Yanaka

Patent number: 6803675Abstract: A holder coil spring is located between an inner surface of a bottom of a case main body and a bottom outer surface of a shutter holder. A shutter coil spring is located between a bottom inner surface of the shutter holder and a shutter. In each sidewall of the shutter holder, a tactile feedback piece and a locking piece are provided. The tactile feedback piece holds the shutter holder at the case main body. The locking piece locks an electronic key in the shutter holder. Even if an object other than the electronic key (for example, a finger) is inserted in the slot, the object is not locked in the shutter holder. When the object other than the electronic key is pulled out of the slot, the shutter holder and the shutter return to original positions to close the slot. Therefore, when no object is inserted, the slot of the slot mechanism is reliably closed with the shutter.Type: GrantFiled: November 3, 2003Date of Patent: October 12, 2004Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Shoichi Harada, Tomoyuki Funayama, Hiroyuki Yamada, Yoshinori Fukuoka

Publication number: 20040183376Abstract: A vehicle theft deterrent system comprises a battery switch, an actuation device and a signal receiver. The battery switch is configured for enabling electrical continuity of a power cable connected between a battery and a starter of a vehicle starting system to be selectively broken and made. The battery switch is in a starting system disabled mode when the electrical continuity is broken and in a starting system enabled mode when the electrical continuity is made. The actuation device is connected to the battery switch and is configured for selectively switching the battery switch between the starting system disabled mode and the starting system enabled mode. The actuation device is connected to a switching mechanism of the battery switch and is configured for moving the switching mechanism between a first position corresponding to the starting system disabled mode and a second position corresponding to the starting system enabled mode.Type: ApplicationFiled: March 19, 2004Publication date: September 23, 2004Inventor: Craig Tarbert

Patent number: 6794848Abstract: When a vehicle, for example, a passenger vehicle stops, electric power is supplied to a passenger compartment mechanism and/or an entertainment device from a power supply isolated from the device relating to a vehicle travel system. Electric power consumption is managed to secure the electric power necessary to create a travel start possible state. Further, a key position is provided to supply electric power only to the passenger compartment mechanism and/or the entertainment device. With this arrangement, music and the like can be comfortably enjoyed by stopping the vehicle.Type: GrantFiled: June 13, 2002Date of Patent: September 21, 2004Assignee: Sony CorporationInventors: Akira Shinada, Katsuhiko Nunokawa, Hiroaki Okajima

Publication number: 20040160314Abstract: A vehicle-motion based vehicle theft detection device uses preexisting vehicle motion sensors in combination with an engine immobilizer system to detect and deter potential vehicle theft. Depending on whether or not a valid ignition key is in use, the engine immobilizer system sends signals to an electronic module to enter either a “disarmed” or “armed” state. When a vehicle sensor relays a signal to an electronic module, the electronic module determines, based on this signal, if the vehicle is in motion. If a valid key is in use, the electronic module is in a disarmed state and takes no further action, as the motor vehicle is authorized for motion. If, however, a valid key is not in use, the electronic module is in an armed state, and activates the vehicle alarm system which, in turn, may activate an audible or visual alarm, activate a remote notification device, generate a tracking signal, and/or store evidence of unauthorized vehicle motion in memory.Type: ApplicationFiled: February 18, 2003Publication date: August 19, 2004Inventors: Thomas E. Utter, David T. Proefke

Publication number: 20040145241Abstract: An object of the present invention is to prevent a start-up locked state from being released by a third party other than a rightful driver. After a movable body 31 has been set in a state of halted operations (a start-up locked state) by a start-up lock setting unit 830, a rightful driver must contact a manager on a terminal device 11 side when this driver forgets a password or hands over to another driver. Having received contact, the manager transmits a start-up lock release command from the terminal 11 side to the movable body 31 via communication units 1 (see FIG. 1), whereby the state of halted operations (start-up locked state) in the movable body 31 is released.Type: ApplicationFiled: January 24, 2003Publication date: July 29, 2004Inventors: Shuji Arakawa, Tadashi Morita

Publication number: 20040135435Abstract: A system for preventing the unauthorized by-pass of an OEM security system is disclosed. The system includes an OEM starter for starting a vehicle; an OEM security system in communication with said starter; a by-pass kit for by-passing said OEM security system and enabling remote car starting of the vehicle without placing the key in the ignition; a remote car starter device in communication with the by-pass kit for sending a signal to the by-pass kit to start the engine; and a remote car starter transmitter in wireless communication with the remote car starter device. The signal that is sent to said by-pass kit is data, so that the by-pass kit is adapted to by-pass the OEM security system only upon receipt of the data signal. The improvement can be brought to both transponder-based bypass kits and microprocessor-based bypass kits.Type: ApplicationFiled: July 7, 2003Publication date: July 15, 2004Applicant: Automobility Distribution Inc.Inventor: Robert A.

Patent number: 6756885Abstract: A control system includes a transmitter, a receiver for receiving signals from the transmitter, and a multi-vehicle compatible controller cooperating with the transmitter and receiver. The multi-vehicle compatible controller is for storing a set of device codes for a given vehicle device for a plurality of different vehicles, for reading a device code from a data communications bus, and for determining a match between a read device code and the stored device codes to thereby provide compatibility with a plurality of different vehicles. Such an arrangement provides for a relatively simple and straightforward approach to interface with a vehicle having a data communications bus. The multi-vehicle compatible controller may include a memory for the stored device codes, and a processor cooperating with the memory for determining the match between the read device code and the stored device codes.Type: GrantFiled: May 31, 2000Date of Patent: June 29, 2004Assignee: Omega Patents, L.L.C.Inventor: Kenneth E.

Patent number: 6748536Abstract: A system for providing a key-based access to data stored on a vehicle allows the vehicle to be a critical link as a platform for mobile computing while preserving data security. Multiple hierarchies of key codes allow all users to have access to all vehicle functions but different memory partitions for storing data. The partitions may be used for storing user specific data including passwords, preference settings, and driving log data. The data may be encrypted by the key code to be secure even if the memory system is removed from the vehicle or the vehicle is stolen.Type: GrantFiled: January 13, 2000Date of Patent: June 8, 2004Assignee: Visteon Global Technologies, Inc.Inventor: Adrian Madau
