Abstract: An object of the present invention is to provide a user interface method and a device capable of arbitrarily and efficiently performing the dialog through the speech input in an in-vehicle information service system, and a system configuration which can cope with network connection loss with a center is also provided. In addition, the present invention provides the system configuration in which access from a terminal to the center is not always performed but can be performed arbitrarily according to needs. As a terminal-side configuration, a flexible dialog management unit and a task management unit for performing application management are separated from each other. Furthermore, the terminal configuration has a four-tier structure of a user interface, dialog management, task management, and applications. In addition, means for fetching application information from the center in accordance with needs is provided.

Abstract: A speech interaction apparatus starts pushing information to a user and executes a speech interaction about the information in a case where (i) an interaction starting condition for starting pushing the information is set and (ii) the interaction starting condition is satisfied. The speech interaction apparatus includes an interaction policy setting unit and a speech interaction unit. The interaction policy setting unit sets, in consideration of a drive route intended by the user, an interaction policy of certain information which satisfies an interaction starting condition. The speech interaction unit pushes the certain information and executes a speech interaction about the certain information in accordance with the interaction policy set by the interaction policy setting unit. This enables execution of a user-friendly speech interaction while maintaining safety during a drive.

Abstract: A signal processing circuit for removing a noise component from a detection signal of a yaw-rate sensor for detecting a yaw rate generated in a motor vehicle. The processing circuit detects the magnitude of variation of the detection signal of the yaw-rate sensor so as to compare the magnitude of the detection signal with a predetermined reference value. In accordance with the comparison result, the processing circuit outputs a limitation detection signal to limit the variation to below the predetermined reference value. Further, when the magnitude of variation of the detection signal exceeds the predetermined reference value, the processing circuit outputs as the limitation detection signal the yaw rate detection signal immediately before the exceeding, and the predetermined reference value is corrected on the basis of the steering angular velocity of the steering wheel of the motor vehicle. This arrangement allows effectively eliminating a spear-like noise from the detection signal of the yaw-rate sensor.

Abstract: Disclosed is an electronically controlled fuel injection system for controlling a fuel quantity to be injected each cylinder of a diesel engine by a fuel injection pump (5), wherein a positioning servo system is employed which is arranged to calculate a control input value of an actuator (82) in accordance with a signal from an actual position sensor (84) and a signal from a fuel quantity control unit (2) so that the actual position of a fuel adjustment member (83) is coincident with a desired position thereof indicated by the signal from the control unit (2). The servo system comprises a minimum time control unit (7) and a speed estimation unit (9). The minimum time control unit (7) derives the control input value from a map established on the basis of the nonlinear dynamic model of the actuator (82) as a function of a deviation between the actual and desired positions, a current passing through the actuator (82) and a speed of the fuel adjustment member estimated by the speed estimation unit (9).
