  • Patent number: 8862312
    Abstract: A device controls a person protection system of a motor vehicle having a sensor system which, for detecting an object colliding with the motor vehicle, includes a hose arranged along a body section width of the vehicle and closed-off by a pressure sensor on at least one end. In the event of an impact with an object, a pressure change is caused in the hose interior due to deformation of the hose and is detectable as a pressure signal of the pressure sensor by an evaluating unit connected with the pressure sensor. The evaluating unit detects vibrations originating from the motor vehicle during a driving and testing operation and coupled into the hose, which vibrations result in pressure fluctuations in the hose interior which are lower than a pressure fluctuation caused by an impacting object, and evaluates these vibrations for a predefined time period for diagnostic purposes.

The ACM_ECU (200) calculates the number of STGs (S1F) that is a quotient obtained when dividing the phase delay (P1F) of a target current value waveform by an average STG time ((T1)/4) in a first cycle (C1) of engine vibration and the remaining time (P?1F) of the phase delay (P1F), wherein the target current value waveform is used for suppressing the transmission of the engine vibration calculated using the output data from the crank pulse sensor (Sa) and the TDC sensor (Sb). The timing at which the elapse of the STG time equivalent to the number of STGs (S1F) in a third cycle (C3) of the engine vibration in the driving timing of the driving unit has been detected is set as a phase delay reference.

    Abstract: An impact sensor calibration tool, wherein an impact sensor is installed on a vehicle and in wireless communication with a processor, which analyzes data reported by the impact sensor. Specifically, the impact sensor of the present invention continuously measures two dimensional acceleration of a vehicle. Changes in vehicle acceleration create impulse data and the impact sensor reports this data to a processor. The processor performs statistical calculations on the data to identify the vehicle's normal use operation and from this, develops an impact threshold wherein impulses exceeding this threshold are identified as impacts. The impacts may be further characterized as real impacts and stored in memory for subsequent analysis.

    Abstract: A collision detection system includes at least one sensor. The data from the sensor is input to a recursive filter which selectively uses the input to predict the motion of a target object relative to a host vehicle. The recursive filter continues to use the data from the sensor until the target object is within a threshold distance of the host vehicle. Within the threshold distance, the sensor does not reliably provide accurate data. Accordingly, the recursive filter omits the sensor input from motion estimates when the target object is within the threshold distance, which leads to significant improvement in target motion prediction.

    Abstract: An occupant detection system with noise reduction, a controller having noise reduction for an occupant detection system and a method for reducing noise in an occupant detection system. A high order digital filter is used to filter harmonics of a noise signal from an electrode signal used to determine an occupant presence or absence of the occupant. A way of sampling the electrode signal and the implementation of the high order digital filter cooperate such that the signal processing can be performed by a lower cost general purpose microprocessor as opposed to using a higher cost digital signal processor.

  • Patent number: 8180520
    Abstract: The electronic safing system is provided with a safing sensor, a comparator, and a microcomputer. The microcomputer has a programmable analog I/O port which is connected to a built-in AD-DA converter. The programmable analog I/O port can be switched to an analog input port and an analog output port according to an internal register. The programmable analog I/O port is connected to an input terminal of the comparator. When diagnosing the comparing circuit, the microcomputer switches the programmable analog I/O port to the analog output port and outputs a predetermined voltage for diagnosis. Then, the microcomputer diagnoses the comparing circuit by monitoring the output of the comparing circuit.

    Abstract: A sensor detection controller is used in combination with a capacitive sensor that is mounted on a seat of a vehicle in such a manner that a capacitance of the capacitive sensor changes according to whether the seat is occupied. The sensor detection controller has a fault detection mode and a normal detection mode. The sensor detection controller includes a signal source for applying an amplitude signal to the capacitive sensor, a switch for switching a signal path, through which the amplitude signal is applied, between the fault detection mode and the normal detection mode, a signal detector for detecting a change in a voltage or a current of the amplitude signal when the amplitude signal is applied, and an impedance member connected to the signal path.

  • Publication number: 20110282553
    Abstract: An apparatus (50) detects a pedestrian/vehicle impact, the apparatus including a plurality of sensors (62, 64, 66) mounted near a forward location of a vehicle (52), each sensor providing an associated signal indicative of an impact event. A metric determining device (80) determines metric values for each of the sensor signals. A controller (80) determines if any of said determined metric values indicates the occurrence of a misuse event. The controller also determines if a pedestrian/vehicle impact event is occurring by comparing the metric value of at least one sensor signal against a selectable threshold. An actuation signal is provided in response to the comparison. The selectable threshold is selected in response to the determined occurrence of a misuse event. An actuatable pedestrian impact mitigation device (84) is attached to the vehicle and is actuated in responsive to the actuation signal from said controller.

  • Patent number: 8044782
    Abstract: There is provided a system and methods for mitigation of the potential dangers to which at least a child, and passengers, are exposed to prior to, during travel and after travel, when outside and adjacent a vehicle. Potential dangers to which a child is exposed are risks associated with driving and non-driving behavior of the driver, when the child is inside and outside the vehicle, when the vehicle is driven on public roads and on private property grounds, and as a result of deficient of mistaken operation of child and passenger related devices. The system and methods require input commands into an indicator to operate equipment elements aboard the vehicle, including sensors, operable devices and alert systems, and are operative for communication with remote stations, with adjacent-driven vehicles, and with the vehicle owner.

At a main engine operation control section (40), a slip rate determination section (41) calculates the slip rate U of a clutch mechanism (120) of a marine gear (12) in order to rotate the propellers (13) at the target rotation speed. A drive control section (42) controls operation of the main engine (11) and the clutch mechanism (120). Further, in a thruster operation control section (50), a drive control section (52) controls drive of the propeller (14b) in the rotational direction determined by an operation determining section (51).

  • Patent number: 8010141
    Abstract: A system and method for wirelessly transferring content to and from a vehicle, in particular, an aircraft. The content includes, for example, data, voice, video and multimedia, that can be wirelessly exchanged over a wireless communication link between an aircraft and a ground station while the aircraft is at or near a parking gate, or between aircraft. In an example, the system employs long distance metropolitan area technology, such as IEEE Standard 802.16 wireless technology, to increase transfer range. The parameter of the wireless communication link can be adjusted based on, for example, the location of the link. The content can further be provided between the vehicle and ground station based on priorities, such as the available link speed, importance of the information, and/or anticipated connection time between the vehicle and ground station. A media creation center can be networked to a plurality of base stations.
