  • Patent number: 5973410
    Abstract: The safety device, especially in an electronic motor vehicle control system, protects external circuit branches supplied with current from an engine/motor vehicle control unit so that a single short circuit results in failure of only that circuit branch in which the short circuit is located, so that an emergency operation of the electronic motor vehicle control system is possible. The respective reference grounds of the external circuit branches are connected to a common ground conductor (11) via an interface (3) including respective reference ground connectors (d, k, m). Each reference ground connector includes a safety device in the form of thin wire plug bonds, whose maximum current load sets the maximum current load of the respective external circuit branches. Then, if there is a short circuit to the reference ground of the concerned external circuit branch to a main supply voltage, the remaining circuit branches remain unaffected and operational.

  • Patent number: 5973611
    Abstract: The present invention teaches a hands-free remote entry system primarily for vehicles. This system comprises a base transceiver having wake-up sensors for automatically detecting an object. Once an object is detected, a transmitter within the base transceiver transmits a wake-up/data signal to a fob transceiver. A wake-up receiver within the fob transceiver receives the wake-up/data signal. Upon receipt of the wake-up/data signal, the fob transceiver transmits an identification/data signal, via a transmitter, back to a receiver in the base transceiver. In response to receiving the identification signal, output drivers from the base transceiver actuate a door lock system and an auto theft system.

  • Patent number: 5969432
    Abstract: A synchronous rectifier, to which the primary-side input voltage of the transformer and a control voltage with the same frequency as the input voltage is applied, is connected to the primary side of the transformer. The phase of the control voltage can be switched between 0.degree. and 90.degree., so that the output voltage of the synchronous rectifier corresponds exclusively to the voltage drop component at the ohmic input resistance of the transformer at 0.degree., and exclusively to the voltage drop component at the inductive input resistance of the transformer at 90.degree.. Since both the ohmic and the inductive input resistances are dependent on the resistance of the load connected to the secondary side (e.g., the squib of an air bag), both voltage components can be used to obtain reliable information on the status of the load resistance.

  • Patent number: 5969599
    Abstract: An improved deployment method for a vehicular supplemental restraint system having an acceleration sensor and a restraint device to be deployed for occupant protection in a crash event, where the deployment is initiated when a filtered version of the acceleration signal exceeds a deployment threshold that is periodically adjusted based on one or more secondary measures of crash severity and the level of event progression, the level of event progression being based on the value of a filtered acceleration signal relative to one or more predefined event progression thresholds. The deployment threshold is set to a relatively high default level during periods of inactivity to provide good immunity to rough road impacts, while providing timely deployment for high speed crash events, and is periodically adjusted from the default level in the course of a crash event.

  • Patent number: 5961562
    Abstract: A CPU 30 first receives data of accelerations Gx and Gy applied respectively along a longitudinal axis and a lateral axis of a vehicle (S20). The CPU 30 then calculates an arithmetic value fx from the acceleration Gx in the longitudinal direction according to specified arithmetic operations, and calculates an arithmetic value fy from the acceleration Gy in the lateral direction according to specified arithmetic operations (S22). The CPU 30 subsequently projects vectors based on the arithmetic values fx and fy in a preset direction a to yield projective components of the vectors, and determines a sum fa of the projective components (S24). The CPU 30 compares the projective component fa with a threshold value fth(a) previously set for the direction a, and determines whether or not the projective component fa is greater than the threshold value fth(a) (S26).
