A selector device is included for manually selecting between the normal operating mode and the safety lock mode.

Abstract: A vehicle ignition interlock system includes a breath analyzer and a controller operably connected to the breath analyzer and to an ignition system of the vehicle. The breath analyzer detects breath alcohol level of a vehicle operator and prevents vehicle ignition if a breath alcohol level is greater than or equal to a threshold value. The controller requires the vehicle operator to periodically take breath analyzer “retests” after vehicle ignition in order to allow vehicle operation to continue. The breath analyzer includes first and second alcohol sensors. The second alcohol sensor is a backup for the first alcohol sensor and becomes operational if the first alcohol sensor malfunctions. The first or second alcohol sensors may be a mouth contamination sensor that distinguishes between mouth contaminants and alcohol contained within a deep lung breath sample. The system also includes sensors configured to detect impact (abuse) and vehicle motion.

Abstract: A vehicle with a high voltage power source mounted thereon has a diversity of protection mechanisms to protect the driver and mechanics from potential accidents. Even in the case of a subtle erroneous operation or detection, one of such mechanisms cuts off the supply of the high voltage power source. This undesirably lowers the convenience of use. The arrangement of the present invention carries out evaluation and determines that the driver intends to start the vehicle in a normal manner, when the time on a first timer Toff is greater than a preset minimum off time Tmin, for example, 5 seconds but less than a preset maximum off time Tmax, for example, 1 hour. Based on this evaluation, system main relays SMR are set on to permit a start of the vehicle.

Abstract: A restraint and fuel pump cutoff control system is disclosed wherein a restraint control module controls the restraint system such as an air bag deployment system and a fuel system power supply based upon data inputs from sensors positioned at various locations on the vehicle. When data received from the sensors indicates that a collision event has occurred and has reached the predetermined level of severity, power to the fuel system is cut off to prevent undesired pumping of fuel. If power is interrupted during a collision event, the fuel system will be cut off and remain cut off until reset by turning the ignition switch to off and then to run/start indicating a clean shutdown. The restraint control module utilizes collision data profiles to distinguish between power shutdowns occurring during a collision event and power shutdowns occurring when only background data is being received from the sensors.

Abstract: A driver briefly places his hand upon a biometric hand reader once during each successive four minute recurrent time interval established by a microprocessor that continuous to produce a maintain-truck-operative signal to prevent truck disablement that would otherwise occur while driving. Should a hijacker drive the truck away and use the hand reader, the reader senses a mismatch, will cease to produce the maintain-truck-operative signal, and the truck will stop. The hijacker is prevented from occupying the cab and forcing the driver to drive and use the sensor by a switch-mat within the passenger area that senses the hijacker's presence and disables the truck. A facial recognition reader will stop the truck if the driver is absent in an even faster manner, which is very important when a gasoline truck that is a bomb-on-wheels is stolen. More affordable data input sensors comprising a steering wheel pushbutton encoder are also disclosed.

Abstract: When an ignitor 29 is ignited by an abnormal signal sent from outside, a heating agent 27 charged into a thermite case 26 is heated, a retainer 45 is melted by the heat, a compression spring 39a is expanded to allow the thermite case 26 to move up. Therefore, electrical connection between the thermite case 26 and each of a first bus bar 11a and a second bus bar 19a is interrupted. Thus, it is possible to reliably interrupt a circuit within a short time. Further, a low-melting metal 28 mounted to an intermediate portion of the second bus bar 19a is blown out by heat caused by a current flowing through the second bus bar 19a to interrupt the circuit. Therefore, even if an abnormal signal is not sent to the ignitor 29 due to failure of a control circuit or the like, it is possible to reliably interrupt the circuit.

Therefore, the ignitor 29 ignites, a second projection 41 is melted by heat of a heating agent 27, a compression spring 34 is expanded and a thermite case 26 jumps up. Thus, electrical connection between the thermite case 26 and the first and second buss bars 11, 19 is interrupted.

Consequently, a short circuit that might occur in the event of an accident and which could otherwise lead to damage of the cable tree and then set the vehicle on fire, is avoided in good time.
