Abstract: An apparatus for controlling a hybrid vehicle having an internal combustion engine and an electric motor as driving sources for the vehicle, in which when it is detected that an air-fuel ratio of a supply air-fuel mixture to the engine changed to the lean side value (S44˜S46), the electric motor (2) is made operative as a motor in order to assist an output of the engine just after the detection (S47, S48). When it is detected that the air-fuel ratio of the supply air-fuel mixture changed to the rich side value (S44, S52, S53), the electric motor (2) is made operative as a generator for the purpose of the regeneration braking just after the detection (S54, S55). An output torque difference of the engine, therefore, when the air-fuel ratio of the supply air-fuel mixture changes can be sufficiently compensated without a time delay.

Abstract: In a control system for a gas turbine aero engine, without using the engine inlet sensors, the engine inlet condition data including the intake air temperature and the intake air pressure is estimated based at least on the detected rotational speed of the turbine, the detected inlet pressure of the turbine and the detected atmospheric pressure, etc. through reasoning. Thus, the system can remove the engine inlet sensors (which are generally expensive) and instead, enables to estimate the engine inlet condition data necessary for controlling the engine with a relatively simple configuration.

Abstract: A locking device for a parking brake is provided which ensures that the operation of locking a parking brake lever and the operation of releasing the locking of the parking brake lever can be carried out in a single stage. The parking brake lever is pivotally supported on a mounting bracket mounted on a steering handle by a first support shaft, and a lever locking member is pivotally supported on the mounting bracket by a second support shaft, and biased by a torsion spring.

Abstract: The thrust T of an airplane is estimated by a thrust estimating device, and the motion state (the speed, the angular speed, the attitude angle and the elevation angle) of the airplane is detected by a motion state detecting device. Then, a drag estimating device estimates the drag D of the airplane, based on the thrust T and the motion state of the airplane. An operation-amount calculating device converges the steering angle into a target steering angle at which the drag of the airplane is minimized, by repeating the operation of varying the steering angle of a flap by a very small angle by an operating device, and further varying the steering angle by a very small angle, while monitoring the increase or decrease in drag resulting from such variation. Such a drag reducing control is carried out, while monitoring the actual drag and hence, is extremely effective, and also can exhibit an effectiveness, irrespective of the motion state of the airplane.

Abstract: A system for discriminating degradation of an exhaust purification system of an internal combustion engine having an adsorbent installed at a bypass exhaust gas passage branched from an exhaust pipe of the engine, which is opened by a switch-over valve at starting of the engine to introduce the exhaust gas such that the adsorbent adsorbs unburned HC in exhaust gas generated by the engine and is closed such that the adsorbent desorbs the adsorbed HC and the desorbed HC is thereafter recirculated at a position upstream of a catalyst. Based on the fact that the HC concentration rising time interval becomes short as the adsorbent degrades and adsorption capacity decrease, the time lapse since engine starting until the detected HC concentration exceeds a predetermined level is measured and is compared with a threshold value such that the adsorbent is discriminated to be degraded if the measured time lapse is less than the threshold value, thereby enabling to improve the discrimination accurately.

Abstract: A torque transducer comprises a rotating shaft having first and second torque input members connected by a torsionally compliant coupling thereby enabling angular deflection of the torque input members relative to each other as a function of the magnitude of the torque in the shaft. The transducer has an EMR source and an array of EMR sensitive detectors. Each of the torque input members has a grating zone with alternating regions of high and low transmissibility to the EMR. The grating zone resides in the transmission path communicating EMR from the source to the array. A pattern is produced by incident EMR on the array resulting from the alternating regions of high and low transmissibility of the grating zones residing in the transmission path to the array. The pattern on the array is processed to derive the relative angular deflection of the torque input members and provides a measure of the magnitude of the torque in the shaft.
