An accessory switch SWa and an ignition switch SWi are connected to a sub-relay RL1. A starter switch SWs is connected to a sub-relay RL2. The sub-relay RL2 is turned OFF when welding occurs in the starter switch SWs. When welding occurs in the accessory switch SWa, the starter switch SWs is turned OFF, or the starter switch SWs is not turned ON.

A starter circuit includes a start detection circuit for detecting a change of an input signal and outputting a start digital signal, a digital OR circuit for outputting a determination digital signal based on the start digital signal, a power supply circuit being activated based on the determination digital signal, and a digital control circuit being operated based on a power from the power supply circuit. The digital control circuit inputs a retention signal to the digital OR circuit for maintaining an operation of the power supply circuit and a reset signal to the start detection circuit for resetting the start detection circuit.

The present invention is a remote de-activation system for use with vehicles or other motorized equipment consisting of a remote portable RF signal generation unit which communicates with an RF receiver mounted on the vehicle to be disabled. The receiver unit features circuit interruption switching or relays and is transposed within the ignition circuit of the vehicle or equipment to be disabled. The system is further characterized as including independent power sources for the RF transmitter, receiver and alarm systems such as to prevent malfunction of the system through compromising the power sources. Alternative embodiments include the utilization of a centralized battery charger and key locks.

A system and method is described for alerting authorities during a vehicle carjacking or carnapping. The method includes a first step of providing a vehicular radiotelephone communication system with speech recognition and a controller operable to monitor at least one vehicular system. A next step includes defining at least one predetermined sequence of operation of the at least one vehicular system for triggering a silent alert. The sequence can include spoken words or vehicle control operation. A next step includes monitoring the at least one vehicular system for the defined at least one predetermined sequence, such as a hidden switch activation for example. A next step includes activating a silent alert upon detection of the at least one predetermined sequence.

An immobilizer monitors the ignition status of a motor vehicle, in a low power sleep mode or while performing other tasks, and is responsive to a change in ignition status between an off state and an on state to become active from the sleep mode or to interrupt the other tasks. If the change is to an on state, the immobilizer initiates ignition control module interrogation of an ignition control module to check for a valid key in the ignition, authorizes or prevents engine operation according to the result and returns to the sleep mode when finished. If the change is to the off state, the immobilizer again initiates ignition control module interrogation of the ignition control module to check for a valid key in the ignition and sets a key in status datum true or false according to the result. Either the immobilizer itself or a separate body computer responsive to the key in status datum provides a key in ignition warning when a key in status datum of true is detected simultaneously with an open driver door. When the key in status datum is set false, the immobilizer returns to sleep mode or its other tasks.
摘要:
Means for disabling an automobile by causing an on-board computer to disable the ignition system thereof. A radio receiver provides a signal to the on-board computer through an existing port (e.g. diagnostic port or ignition interface port). The on-board computer disables ignition function through supplanted firmware that recognizes the status of the signal received from the radio receiver. Removal of the radio receiver also disables the ignition system. The entire system is installed during government required inspections (e.g. a smog check).

An in-vehicle device data communicates with Internet based data processing resources for the purpose of transacting e-mail, e-commerce, and e-business. The in-vehicle device and the Internet based data processing resources can effectuate a wide variety of e-mail, e-commerce, and e-business including accessing auto part databases, warranty, customer, and other remote databases. In addition, e-mail, e-commerce, and e-business transactions can include vehicle security and vehicle service management, data communicating Internet based radio, audio, MP3, MPEG, video, and other types of data. Furthermore, e-mail, e-commerce, and e-business transactions can include interactive advertising, promotional offers, coupons, and supporting other remote data communications. The in-vehicle device can also include functionality for remote monitoring of vehicle performance, data communicating and accessing remote Internet based content and data, and effectuating adjustments and control of vehicle operation. Remote monitoring and control of vehicle operation can be by way of an Internet based data processing resource and can include engine control system programming and setting adjustment, vehicle monitoring, and transmission of vehicle telemetry and metric data. Vehicle telemetry and metric data can include global positioning system (GPS) data, vehicle operational data, engine performance data, and other vehicle data. The in-vehicle device can also wirelessly data communicate with a communication interface device (COM device) or an Internet appliance. Such COM devices or Internet appliances can data communicate wirelessly with an in-vehicle device and simultaneously data communicate in a wired or wireless mode of operation to Internet based data processing resources, and to other data processing resources.
摘要:
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.
摘要:
A self-contained safety and security system and method that performs the multiple functions of theft deterrence, battery saving, battery analysis system, accident protection, and telemetry and control data communication for vehicles is disclosed. The electronically-based system for a vehicle having an existing power transmission circuit including a battery that can be readily installed and made operational by an individual having no special training using common household tools. The system requires the installation of no dedicated wiring in the vehicle. Furthermore, the system preferably installs without any cutting or splicing of the wiring in the vehicle's electrical system. The system preferably includes an electrical activity sensor sensing electrical activity on the power transmission circuit, a motion sensor sensing vibration associated with the vehicle, a battery-disconnect switch, and a controller to receive signals from the electrical activity and motion sensors and control the switch.
