Patent number: 9828111Abstract: Estimating the speed of an aircraft estimates three components of the speed vector (TAS, AOA, SSA) of an aircraft relative to the surrounding air. The static pressure is estimated on the basis of measurements of geographical altitude. A first intermediate variation of a linear combination of the three components of the speed vector of the aircraft relative to the surrounding air is estimated using explicitly the fact that the pressure measured by the static probe is falsified by a known quantity under the effect of the three components of this speed vector of the aircraft relative to the surrounding air. The process then estimates the three components of the speed vector of the aircraft relative to the air by likening the latter to the speed vector of the aircraft relative to an inertial reference frame and by using inertial measurements. The various estimates are fused to provide a final result.Type: GrantFiled: July 10, 2015Date of Patent: November 28, 2017Assignee: ThalesInventors: Christian Mehlen, Jacques Coatantiec

A tell-tale indicator is deactivated and/or a vehicle control system resumes normal operation if the wheel speed sensor passes the signal check.Type: GrantFiled: August 20, 2010Date of Patent: June 18, 2013Assignee: Robert Bosch GmbHInventors: Henrik Bechtler, Ravi Bhadange, Nachiket Patil, Takeshi Tokonaga, Stefan Mallmann, Michael Schwab, Dietmar Stapel, Willy Klier, Joerg Eesmann

Patent number: 8442724Abstract: A passenger protection system includes: a sensor outputting a detection digital data corresponding to collision; a passenger protection device; and an ECU. The sensor outputs a bit sequence providing an important bit group. A memory stores the data and the sequence doubly for storing first and second detection digital data and first and second bit sequences. The ECU determines based on the first or second data whether it is necessary to protect the passenger when the first data is equal to the second data. When the first data is different from the second data, and the first sequence is equal to the second sequence, the ECU replaces the important bit group in the first or second data with the first or second sequence, and determines based on the first or second data after replacement.Type: GrantFiled: March 16, 2010Date of Patent: May 14, 2013Assignee: Denso CorporationInventor: Tetsuya Uehira

Publication number: 20130090803Abstract: A method for validating information, wherein a first information item is detected essentially continuously, at least for the duration of its relevance, by a vehicle-to-X communication device, wherein a second information item is detected at the same time as the first information item by at least an individual sensor or a group of sensors, wherein the at least one individual sensor or the group of sensors is coupled at the data level to the vehicle-to-X communication device and wherein the first and/or second information items are validated by reconciling an information content of the first and second information items in the case of corresponding information content. The method is distinguished by the fact that the second information item is detected in an essentially discontinuous fashion.Type: ApplicationFiled: June 22, 2011Publication date: April 11, 2013Applicant: CONTINENTAL TEVES AG & CO.

Patent number: 8412425Abstract: An exemplary transmission system includes a plurality of sensors each configured to output a signal at least partially representative of a speed of at least one of a first transmission input shaft, a second transmission input shaft, a transmission output shaft, and an engine. A transmission control module is in communication with the plurality of sensors and is configured to identify at least one of the plurality of sensors as a failed sensor and another of the plurality of sensors as a working sensor. The transmission control module is further configured to estimate the signal of the failed sensor based on a predetermined relationship between an expected signal from the failed sensor and the signal received from the working sensor.Type: GrantFiled: February 12, 2010Date of Patent: April 2, 2013Assignee: Eaton CorporationInventors: Kerfegar Khurshed Katrak, Ian Daniel McKenzie, Anthony Stasik, Jeffrey P.

Patent number: 8401730Abstract: A controller for indicating whether a previously-detected, acceleration-sensor malfunction no longer exists. The controller includes an electronic memory and an electronic processing unit connected to the electronic memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The signal checking module performs a signal check after the malfunction monitoring module generates the fault signal. The signal check includes executing a signal check function with a lateral acceleration signal. Also disclosed is a vehicle including the controller, and a method executed by the controller.Type: GrantFiled: August 20, 2010Date of Patent: March 19, 2013Assignee: Robert Bosch LLCInventors: Henrik Bechtler, Ravi Bhadange, Nachiket Patil, Takeshi Tokonaga, Stefan Mallmann, Michael Schwab, Dietmar Stapel, Willy Klier, Joerg Eesmann

Publication number: 20120310469Abstract: A method (2) for detecting the malfunctioning of a sensor (11) of the pressure of a gas inside a tire of a vehicle includes at least a step (20) of determining whether a predefined gas temperature variation detection criterion is verified. If a temperature variation is detected, the method (2) includes a step (21) of determining whether a predefined criterion for detection of the variation of the pressure, measured by the pressure sensor (11), is verified. If a pressure variation is not detected, the method (2) includes a step (22) of notifying that a malfunction of the pressure sensor (11) has been detected. A device for detecting the malfunctioning of a sensor (11) of the pressure of a gas inside a tire of a vehicle is also described.Type: ApplicationFiled: February 18, 2011Publication date: December 6, 2012Applicants: CONTINENTAL AUTOMOTIVE GMBH, CONTINENTAL AUTOMOTIVE FRANCEInventor: Youri Vassilieff

Patent number: 8303174Abstract: A temperature sensor plausibility diagnosis unit performs plausibility diagnosis of a temperature sensor disposed inside a storage tank in an exhaust purification apparatus of an internal combustion engine that delivers an additive inside the storage tank to an exhaust pipe upstream of a reduction catalyst and selectively reduces and purifies NOx in the exhaust. The temperature sensor plausibility diagnosis unit includes an additive heat capacity calculating portion that calculates the heat capacity of the additive, a heat quantity variation calculating portion that calculates an increase or decrease in the quantity of heat that the additive receives, and a plausibility diagnosing portion that determines the plausibility of the temperature sensor by comparing an estimated temperature course of the additive estimated from the heat capacity of the additive and the increase or decrease in the quantity of heat with a sensor temperature course of the additive detected by the temperature sensor.Type: GrantFiled: October 31, 2008Date of Patent: November 6, 2012Assignee: Bosch CorporationInventor: Hiroyuki Kasahara

Publication number: 20120245830Abstract: In a method for monitoring a coolant temperature sensor and/or a cylinder head temperature sensor of a motor vehicle, during a start (t=tSt) of an internal combustion engine of the motor vehicle an actual value (TCOist=TCOSt) of a coolant temperature (TCO) is determined by a coolant temperature sensor, and an actual value (TCYLHist=TCYLHSt) of the cylinder head temperature (TCYLH) is determined by a cylinder head temperature sensor, wherein the coolant temperature sensor and/or the cylinder head temperature sensor are diagnosed as functional sensors when the actual values (TCOist, TCYLHist) of the coolant temperature (TCO) and the cylinder heat temperature (TCYLH) deviate in the same direction upward in relation to an outside temperature (TAM) and/or an intake air temperature (TIA). By a control device, particularly a motor control device, a method can be and is carried out accordingly.Type: ApplicationFiled: December 9, 2010Publication date: September 27, 2012Inventors: Gerhard Eser, Stefan Seyfferth
