Abstract: An anti-theft vehicle alarm system includes an acceleration sensor acting as a tilt sensor, a microcomputer, a first power source for supplying a first voltage to the microcomputer, and a second power source for supplying a second voltage to the acceleration sensor. The microcomputer calculates a tilt angle of a vehicle from output of the acceleration sensor and activates an alarm in accordance with the tilt angle. If the second voltage is outside a predetermined voltage range, for example, due to a reduction in battery voltage, the microcomputer temporarily stops to activate the alarm to prevent a false alarm. The microcomputer monitors the second voltage not the battery voltage. Thus, even when the second voltage is outside the threshold range, for example, due to a breakdown in the second power source, the false alarm can be prevented.

Abstract: In the device a controllable switch is built into the control device which enables the start authorization and by means of which the supply voltage with which this controllable switch is supplied can be switched off. To check a start authorization a diagnosis can be undertaken which is realized with known resistance elements in the voltage supply line between identification device holder and control device.

Simple short circuiting of the starter or the ignition is thus no longer possible since this would be detected by the control device as a result of the changes in voltage drop. In addition a fault in the supply voltage or the feed lines can be definitively detected.

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.

Also attached to the wire, at a location downstream of the anti-whiplash system, is a sensor that is configured to detect a change in the current flow through the wire. When the anti-whiplash system is activated, the moving parts shear the plastic plug and the wire contained inside, thus breaking the electrical circuit. The current sensor detects this change in current and then activates a warning signal indicator which provides notice to a vehicle occupant that the anti-whiplash system has been activated.

Thereafter, a portion of the accumulated data is transmitted from a detected vehicle in response to instructions generated by the receiving station.

Abstract: A method and apparatus for storing reference information in a non-volatile memory unit when a power loss to a vehicle detector is imminent. A power monitor circuit senses an impending power loss. In response, the vehicle detector transfers reference information, including a reference count and the number of loop cycles over which the reference count was accumulated, as well as optional detector status information, from the vehicle detector volatile memory (typically RAM) to the non-volatile memory unit. When power is resumed, the information stored in the non-volatile memory unit is restored to the vehicle detector. The restored information prevents improper and potentially dangerous vehicle detector operation caused by the loss of reference information during unpredictable power losses. The transfer operation is not performed if the power loss is due to a mechanical disconnection of power.

Abstract: An electrically heated catalytic converter (EHC) and a battery are connected to an alternator via a changeover switch. The changeover switch connects either of the EHC and the battery to the alternator. The slip-detecting device detects the rotational speed of the alternator from the frequency of the ripple in the output voltage of the alternator when the EHC is connected to the alternator, i.e., when the battery is isolated from the alternator. When the battery is isolated from the alternator, the output voltage of the alternator is raised, and the amplitude of the ripple becomes large accordingly. Further, since the battery is isolated, the ripples in the output voltage are not smoothed by the battery. Therefore, the rotational speed of the alternator is accurately detected. The slip-detecting device detects the slip of the driving belt of the generator based on the rotational speeds of the driver and the alternator.
