摘要:
A sensor arrangement, particularly for a passenger protection system of a motor vehicle, comprising a first group of sensors (10, 12) by means of which a first group of state parameters jointly usable by a first decision making unit connected downstream for detecting a first event can be detected, a first digital unit (20) coupled on the input side to at least one sensor (12) of the first sensor group. The arrangement processes the sensor output signals fed thereto and providing the same for forwarding to the first decision making unit as digital values. A second group of sensors (14, 16, 18), by means of which a second group of state parameters jointly useable by a second decision making unit is connected downstream for detecting a second event can be detected with a second digital unit coupled on the input side to at least one sensor (16, 18) of the second sensor group. The arrangement processes the sensor output signals fed thereto and providing the same for forwarding to the second decision making unit as digital values wherein at least one sensor (10) of the first sensor group is coupled to the second digital unit (22) and at least one sensor (14) of the second sensor group is coupled to the second digital unit (22) and at least one sensor (14) of the second sensor group is coupled to the first digital unit (20). The digital units (20, 22) are coupled on their output sides to a first and a second node (28, 30) combining the digital values.
摘要:
A system for triggering passive occupant safety measures in a motor vehicle is described. The system includes a control unit, a plurality of acceleration sensors for detecting the acceleration caused by an impact of the motor vehicle as well as feed lines assigned to the acceleration sensors, by which feed lines the output signals of the acceleration sensors are transmitted to the control unit which analyzes the signals to determine the type and/or severity of the impact, and triggers appropriate safety measures. The sensors are mounted on a vehicle part of a low structural stiffness on the outer vehicle circumferences, and all surrounding vehicle parts of high stiffness are designed to prevent contact with the sensors after an impact of the motor vehicle of a low or medium severity within a minimum reaction time period.

A surfactant composition includes a first surfactant, a second surfactant, and a polyalkylene glycol. The first surfactant is of the general formula R1—O-(A)mH, wherein R1 is an aliphatic hydrocarbon having 10 carbon atoms, A is an alkyleneoxy group having from 2 to 5 carbon atoms, and m is a positive number. The second surfactant is of the general formula R2—O—(B)nH, wherein R2 is an aliphatic hydrocarbon having from 12 to 14 carbon atoms, B is an alkyleneoxy group having from 2 to 5 carbon atoms, and n is a positive number. The polyalkylene glycol is present in the surfactant composition in an amount of from 3 to 20 parts by weight per 100 parts by weight of the surfactant composition.
摘要:
Occupant protection systems in a motor vehicle are activated in the event of a crash that puts the occupants of the vehicle at risk. A processor-based trigger system evaluates signals of crash sensors and actuates the occupant protection systems. Signatures that are produced by impacts on the vehicle body by means of a crash sensor system are detected and preprocessed directly on site of the crash sensor mounting areas. The crash sensor system includes a plurality of similar multifunctional peripheral crash sensors located in various areas of the vehicle body. The preprocessed signatures or variables derived therefrom are evaluated by means of a crash algorithm associated with the trigger system, in terms of kind, intensity, direction and time of the crash signatures and/or occupant risk signatures. Crash-relevant occupant protection systems are triggered at respective times determined in terms of the achievable protective effect of the occupant protection system when occupant risk threshold values are exceeded.

A vehicle includes an airbag system, a sensor unit, which includes a first sensor module, which permits the sensing of actual driving conditions, and an electronic system, which fires the airbag system in the event of a crash and which is designed to evaluate the sensor signals that are provided by the sensor unit. The electronic system carries out a comparison of sensed actual driving conditions with predetermined critical driving conditions, which indicate a crash. The sensor unit includes a second sensor module, which senses in advance the environmental conditions of the vehicle, which after a certain period of time may lead to critical actual driving conditions. Critical actual driving conditions, whose imminent occurrence has been indicated in advance by the second sensor module, are rated by the electronic system as crash-free driving conditions.

A restraint system, in particular for a motor vehicle, includes a restraint device, to be activated in at least two steps; a sensor unit for sensing activation-relevant vehicle and operating data; a control device for processing the activation-relevant vehicle and operating data; as well as an ignition unit for driving the actuators for activating the at least one restraining device. To increase the safety of such a restraining device, at least two independently switched ignition units are provided such that, when one ignition unit fails, the activation of the restraint device in at least one step is guaranteed by the other ignition unit.
摘要:
A position monitoring means for detecting the locked position of a locking element is assigned to at least one locking element. Furthermore, each position monitoring means is operatively connected to a control means for checking on whether a proper locked state prevails such that the actual state and the setpoint state of the locking element are comparable so that if these states do not correspond, an acknowledgment signal can be generated. In this way, it is possible to check on whether all the doors and hatches of a vehicle are properly locked after a locking operation has been performed.
