The present invention is a travel locus generating device that generates a future travel locus of a vehicle and is characterized by including a restriction condition calculating means for performing a convergence calculation of restriction conditions including at least a condition of a road boundary and an evaluation function calculating means for deriving a travel locus by a convergence calculation using an evaluation function, which includes at least evaluation of a variance of speed, in a state where the restriction conditions of the restriction condition calculating means are satisfied.

Abstract: The invention relates to a method for aiding the maintenance of a system, the system comprising a set of networked elements, the system being accompanied by indications defining subsets of networked elements Ei, each subset of networked elements Ei being associated with a probability of failure Pi, the including the steps of calculating a first value Ti for each subset of networked elements Ei, the first value Ti including an estimation of the maintenance time related to the repair of the subset of networked elements Ei, calculating a second value Fi for each subset of networked elements Ei, the second value Fi including a representation of a compromise between the estimation of the maintenance time Ti related to the repair of the subset of networked elements Ei and the probability of failure Pi of the subsets of networked elements Ei, and sorting the designated sets of items of equipment Ei in order of decreasing second value Fi.

Abstract: An apparatus includes a first memory device, a second memory device and a controller. The first memory device stores vehicular data in accident. The second memory device has control data area for storing control data in nonvolatile manner. The controller records the vehicular data stored in the first memory device into the control data area of the second memory device by overwriting the control data in response to vehicular accident. It is possible to increase a recordable amount of vehicular data in vehicular accident without increasing recording capacity exclusively preserved to vehicular data.

Abstract: A method for compensating for wheel speed and acceleration calculation errors comprising the steps of collecting a wheel speed signal, creating at least one compensation factor for the wheel speed signal, correlating each compensation factor with a rotational position of the wheel, modifying each compensation factor individually based on variations in calculations made from the information collected according to the rotational position of the wheel, and calculating wheel speed and acceleration using the at least one compensation factor applied according to the rotational position of the wheel from which the wheel speed signal is collected.

Abstract: The method for generating an integrated guidance law for aerodynamic missiles uses a strength Pareto evolutionary algorithm (SPEA)-based approach for generating an integrated fuzzy guidance law, which includes three separate fuzzy controllers. Each of these fuzzy controllers is activated in a unique region of missile interception. The distribution of membership functions and the associated rules are obtained by solving a nonlinear constrained multi-objective optimization problem in which final time, energy consumption, and miss distance are treated as competing objectives. A Tabu search is utilized to build a library of initial feasible solutions for the multi-objective optimization algorithm. Additionally, a hierarchical clustering technique is utilized to provide the decision maker with a representative and manageable Pareto-optimal set without destroying the characteristics of the trade-off front. A fuzzy-based system is employed to extract the best compromise solution over the trade-off curve.

Abstract: A vacuum brake booster and a method of operation of a vacuum brake booster of a vehicle brake system is disclosed. The vacuum brake booster includes a housing subdivided into at least one vacuum chamber and at least one working chamber. The vacuum chamber is connected to a vacuum source by way of a vacuum port. A sensor unit is associated with the vacuum chamber and is configured for sensing a pressure in the vacuum chamber and supplying a sensed pressure value to an electronic control unit (ECU). The ECU includes an evaluating unit for evaluating the sensed pressure value and calculating the operating point of the vacuum brake booster solely on the basis of the sensed pressure in the vacuum chamber. Plausibilization of the sensed pressure value is performed to monitor the overall system and identify defects of the sensor unit or the vacuum brake booster.
