Abstract:
When starting an engine using its remote engine starter function in a guard mode, an engine control ECU outputs an engine status signal at H level prior to driving a starter motor. An anti-theft control device, upon reception of the signal, stores the engine operating status in a mode storage device and lower the detection sensitivity of sensors. This allows no false alarm to be generated, if the anti-theft system is initialized by the decreased voltage of battery at the time of driving the starter motor. In addition, the detection sensitivity of the sensors is low until the engine stops running, so that the sensors do not have risks torroneously detect the vibration of vehicle as an intruder.
Abstract:
A vehicle control system for a vehicle having a door lock actuator includes a remote keyless entry (RKE) system including an RKE transmitter carried by a user, an RKE receiver at the vehicle, and an RKE controller connected to the RKE receiver for selectively operating the door lock actuator based on signals from the RKE transmitter. A piggyback controller at the vehicle is connected to the door lock actuator for performing at least one desired piggyback control function based on selective operation of the door lock actuator by the RKE controller. The piggyback controller may switch to a feature programming mode based on selective operation of the door lock actuator. When in the feature programming mode, the piggyback controller may permit feature selection also based on selective operation of the door lock actuator. The piggyback controller may also be switched to an override or valet mode based on selective operation of the door lock actuator.
Abstract:
A security arrangement for motor vehicle equipped with a programmed monitoring system (1) and with at least one specific system (2) to which the monitoring system transmits commands. The arrangement comprises hard-wired logic (4) mounted between a control facility (3) and the specific system, as is the monitoring system. This logic makes it possible to block a command (OV) transmitted by the monitoring system to the specific system, when this command corresponds to that which is obtained in respect of an instruction (C) received by the control facility and when such an instruction has not been received from the control facility by the hard-wired logic. The arrangement is intended to be fitted to a vehicle comprising a programmed monitoring system, such as a “hands-free” monitoring system, and one or more specific systems, for example an electrical anti-theft system or electrical supply monitoring system.
Abstract:
Anti-theft circuit for a portable device, is disclosed, in which a correlation in a PN(Pseudo Random Number) sequence is employed for effective prevention of a portable device from being thieved, the anti-theft circuit including a transmission block disposed in the portable device having a block for generating a particular pseudo random number sequence and a multiplication block for always multiplying a ‘high’ value to an output of the block for generating a particular pseudo random number sequence, the transmission block for converting an output of the multiplication block into an analog value and transmitting the analog value, and an anti-theft sensing circuit separate from the portable device for receiving a signal transmitted form the transmission block, sampling the signal, multiplying a sampled value to a pseudo random number sequence identical to a case of the transmission block, summing for a time period, comparing to a preset threshold value, and selectively providing an alarm signal to outside thereof according to a result of the comparison.
Abstract:
A vehicle security system 10 having an improved signaling methodology 22 which results in a decrease in the power consumed by the vehicle security system 10.
Abstract:
A vehicle security system includes a siren for sounding a siren security alarm to supplement a horn security alarm responsive to operation of the horn in a predetermined pattern, such as by a security controller. The siren may not sound the siren security alarm responsive to selective occasional operation of the horn, such as by the user. The vehicle may include a horn being electrically operable, and a horn switch permitting selective occasional operation of the horn by a user. The vehicle security system may also include the security controller for operation of the horn in the predetermined pattern to sound the horn security alarm responsive to at least one security sensor, such as for a vehicle security breach. The vehicle security system can be readily installed, or the siren can be readily interfaced to an existing security system, for example. The vehicle also typically includes an ignition switch being switchable between ON and OFF positions, and the siren may sound the siren security alarm further responsive to detecting the ignition being in the OFF position. In addition, the siren may not sound the siren security alarm further responsive to detecting the ignition being in the ON position.
Abstract:
A system for locking/unlocking at least one motor vehicle openable panel comprising transmission/reception devices which are intended for transmitting, from the vehicle, a radio-frequency interrogation signal, which transmission/reception devices are intended to be carried by a user and which, on receipt of the interrogation signal, are intended for transmitting a radio-frequency identification signal so as to actuate the unlocking of the openable panel, which system comprises detection unit which are linked to the transmission/reception devices on the vehicle and which are able to detect, on an identification signal received on the transmission/reception devices, a modification of a parameter of the transmission, between the transmission/reception means of the vehicle and of the user, which may be due to the interposition, between the vehicle and the user, of intermediate transmission/reception devices.
Abstract:
An anti-theft device (2) for a vehicle. The device (2) comprises a valve means (2D) and a control means (2A,2B,2C). The valve-means (2D) is operable to open and close a fuel supply line of a vehicle thereby respectively preventing and permitting fuel flow through said fuel supply line. The valve means (2D) opens in response to an electrical current supply and closes in response to the lack of an electrical current supply. The control means (2A, 2B, 2C) selectively enables and disables said electrical current supply to the valve means (2D). The control means (2A,2B,2C) enables said electrical current supply in response to receiving a specific encoded signal, and disables said electrical current supply at other times.
Abstract:
An electronic license plate including a housing having a generally rectangular configuration. The housing is mountable to the license plate support of the vehicle and is powered by a vehicle power system. The housing has a front face comprised of a digital display. The digital display displays relevant license plate information of the vehicle. The information relates to a license plate number, a state of issue, and an expiration date. The housing includes a memory chip therein for storing the relevant license plate information thereon. The memory chip is in communication with a main computer system of a selected agency. License plate disabling mechanisms are in communication with the memory chip whereby removal of the housing from the vehicle will disable the memory chip and prevent future use of the electronic license plate. In addition, removal of the license plate disables the vehicle. Special status display mechanisms are in communication with the main computer system and with the memory chip whereby a report of theft entered into the main computer system will display such a status on the digital display.
Abstract:
A remote starting device intended chiefly for use in cars that utilizes a pulse signal that is generated by either an RF transmitter, a keypad, or a telephone. The pulse signal is transmitted to a rotating drive attached to the subject ignition. When the device receives the pulse signal, the rotating drive rotates to activate the ignition of the car, thereby starting the engine. The remote starting device operates independently of the car's circuitry using only the car's battery, via the cigarette lighter, as a power source. There is no need to modify the car's electrical system to install the device. This greatly simplifies installation of the device and does not jeopardize any applicable warranty on the car.
