    Abstract: A safety input system for monitoring a sensor can include a voltage sensing circuit configured to produce a first detection output upon sensing a signal exceeding a voltage threshold, and a current sensing circuit configured to produce a second detection output upon sensing the signal exceeding a current threshold and/or voltage threshold. The signal can come from a sensor in an industrial automation system, such as a light curtain. The first detection output can be provided to a first processor, and the second detection output can be provided to a second processor, so that two processors can independently monitor the sensor. The signal can be monitored by separate input systems. Periodically the first processor can inject a first test signal into the input system for the second processor to detect, and the second processor can inject a second test signal into the input system for the first processor to detect.

For a given value of a parameter that when varied modifies a friction generated in each suspension device, the method includes steps of: applying a stress cycle to each suspension device so as to identify a friction present in each suspension device; determining, for each suspension device, a value of an indicator relating to the friction; repeating the applying step and the determining step by varying the parameter so as to obtain a variation of the indicator as a function of the parameter; and for each suspension device, determining an interval of a value of the parameter in which the indicator is greater than a predetermined threshold for the given vehicle.

    Abstract: In the development of a vehicle component, provision may be made for a component to be tested during a test drive. Thus, the behavior of the vehicle component in the event of failure of a sensor, for example, can be tested. The aim is to enable systematic checking of a mode of operation of a vehicle component. An isolation adapter has a terminal for the vehicle component and a switching device that has a plurality of switch contacts to which a respective test circuit can be connected. An electrical connection between the terminal and at least one of the switch contacts can be produced by switching the switching device. Even during switching, there is always an electrical connection to at least one of the switch contacts. The isolation adapter may also have a display unit that mechanically detects a switching position of the switching device.

  • Patent number: 8914188
    Abstract: A system for testing a number of electronic module assemblies (EMAs) that control one or more personal restraint systems. A programmed processor with a computer system transmits signals that instruct the EMAs to perform a diagnostic self-test. The results of the self-test are received by the computer system and stored in a computer readable memory. In one embodiment, the computer system is a cabin management computer system for use on an aircraft.

  • Publication number: 20140350779
    Abstract: Any one of ECUs that are operating detects a present power supply voltage repeatedly. When the voltage detected at the present time is changed from the voltage detected at the previous time, a difference is calculated as a variation value and the repeatedly calculated variation values are integrated to provide a voltage variation integrated value. When the variation of the power supply voltage of an ECU becomes great relatively due to a loose connection in a power supply line, the calculated voltage variation integrated value becomes greater than those of the other ECUs. In addition, when a defect arises in a common power supply source, the voltage variation integrated value increases in all the ECUs. Therefore, each integrated value of the variation values of the power supply voltage in each of the ECUs enables an anomaly diagnosis of an occurrence point of the defect.

  • Patent number: 8892298
    Abstract: A method for detecting a wear condition of a tire utilizes tread pattern elements included on the tire. The elements are adapted to generate first and second acoustic footprint noises (BEA1, BEA2), with one of the first and second acoustic footprint noises being characteristic of the wear condition of the tire. According to the method, a parent frequency spectrum, which is capable of forming a frequency spectrum of one of the first and second acoustic footprint noises, and a child frequency spectrum, which is capable of forming a frequency spectrum of the other of the first and second acoustic footprint noises, are selected from a frequency spectrum of an acoustic signal acquired from the tire. Two detection confidence indices are determined. If each detection confidence index meets a predetermined condition, a warning is emitted indicating that tire wear has been detected.

The powertrain control module includes an engine combustion module that models engine torque based on engine speed and engine pumping losses due to intake and exhaust gasses. A transmission module models transmission torque applied to the engine based on transmission speed and gear. An accessory loads module models torque applied to the engine by accessory loads including at least one of a power steering pump, an air conditioning compressor, a water pump, and an alternator. An oil viscosity module determines engine oil viscosity based on a friction torque and predetermined engine data that coincides with reference oils. The friction torque is based on the engine torque, transmission torque, and accessory loads torque.
