20120116631 | SCHEDULED VEHICLE MANAGEMENT SYSTEM AND METHOD - A vehicle management system and method which analyze diagnostic trouble codes (DTCs) of the past having the same driver environment in order to predict the trouble probability for diagnostic target items in advance and provide the analyzed result to the driver so that the trouble and/or a car accident due to the trouble can be prevented. | 05-10-2012 |
20120166036 | Diagnosis method for implementing a system diagnosis - In a diagnosis method for performing a system diagnosis, e.g., a diagnosis of a physical system, the system is transferred into a plurality of predefined system states, a system characteristic of the system is acquired in at least two system states of the plurality of predefined system states so as to obtain a state-specific curve of the system characteristic, and the state-specific curve of the system characteristic is analyzed in order to obtain a diagnosis result. | 06-28-2012 |
20120239245 | NUMERICAL ANALYSIS METHOD OF A VEHICLE DRIVE - A first analyzing step is a step that conducts numerical analysis of a flow field but does not conduct numerical analysis of a temperature field in a state in which a motor rotor is rotating. The second analyzing step is a step that conducts numerical analysis of both the flow field and the temperature field after the first analyzing step ends. Accordingly, before numerical analysis of the flow field and numerical analysis of the temperature field are conducted together, numerical analysis is conducted first on the flow field in first analyzing step before it is conducted on the temperature field. As a result, compared with when the second analyzing step is executed from the beginning without conducting the first analyzing step, the calculation load of the numerical analysis on an electronic calculator can be reduced, which enables the time that it takes to conduct the numerical analysis to be shortened. | 09-20-2012 |
20120259506 | FAST DETECTION OF ERROR CONDITIONS IN VEHICLE VACUUM SENSORS FOR A HYDRAULIC BOOST COMPENSATION SYSTEM - Systems and methods of monitoring redundant vacuum sensors in the same vacuum chamber of a braking system to determine when an error condition is present in a braking system. The braking system includes a first sensor positioned in a chamber of the braking system and a second sensor positioned in the same chamber. A first reading is received from the first sensor and a second reading is received from the second sensor. A difference between the first reading and the second reading is determined. An error condition is indicated when the difference between the first reading and the second reading is greater than a threshold. | 10-11-2012 |
20130066515 | METHODS AND SYSTEMS FOR COST-BASED CONTROL OF AIRCRAFT HEALTH DATA REPORTING - A method for reporting aircraft data is described that includes receiving, at a processing device, data relating to a condition experienced during operation of the aircraft, determining a cost relevance for the data, comparing, with the processing device, the cost relevance for the data to a threshold, transmitting the data to an end user system if the cost relevance exceeds the threshold, and storing the data in a memory if the cost relevance does not exceed the threshold. | 03-14-2013 |
20130096770 | DEVICE AND METHOD FOR DETERMINING THE STATE OF AGEING OF A HYDRAULIC FLUID OF A HYDRAULIC SYSTEM OF A VEHICLE - A device for determining ageing of a hydraulic fluid in a hydraulic system with a multitude of hydraulic components is provided. The device comprises at least one temperature determination device and at least one ageing determination device, wherein the temperature determination device determines the respective temperature of each discrete fluid volume of the hydraulic fluid in the hydraulic system, and from the aforesaid the ageing determination device determines an increase in ageing. Generally, the temperature determination device carries out a numerical thermal simulation of the hydraulic system, component by component, including determining at least one temperature of at least one hydraulic component of the hydraulic system, which simulation is supported by measuring the temperatures of individual hydraulic components by means of temperature sensors. | 04-18-2013 |

20150032326 | FAILURE DIAGNOSIS APPARATUS OF HYBRID VEHICLE - A failure diagnosis apparatus comprises a controller that is configured to execute a failure diagnosis process of the internal combustion engine based on a predetermined diagnosis requirement. The diagnosis requirement in a case where engine-operation-electric-power supply is executed is made different from the diagnosis requirement in a case where engine-normal-operation is executed such that a failure of the internal combustion engine in the case where the engine-operation-electric-power supply is executed is less likely to be detected or the failure of the internal combustion engine is less likely to be recognized by a driver than in the case where the engine-normal operation is executed. | 01-29-2015 |
20150073650 | METHOD FOR MONITORING A DEGRADATION IN AN ON-BOARD DEVICE OF AN AIRCRAFT WITH AUTOMATIC DETERMINATION OF A DECISION THRESHOLD - A method for monitoring a degradation in an on-board device of an aircraft, comprising a step of comparing an abnormality score obtained for a given flight of said aircraft with a decision threshold (S) and a step of transmitting an alert in the event of said decision threshold (S) being exceeded, said decision threshold (S) being automatically determined for a given probability of alert Pa, corresponding to the probability of an alert being transmitted during the monitoring method when said on-board device is healthy, by means of a plurality of steps, including a step of reading the antecedent of the continuous adjusted division function for the value 1−Peac, said antecedent corresponding to said decision threshold (S), with Peac being the elementary probability of exceeding the threshold for confirmation per k exceedances of threshold during n consecutive flights and being a function of the probability of alert Pa. | 03-12-2015 |
