摘要： PURPOSE:To accurately detect an output torque transmitted to a counter shaft so as to improve control accuracy by arranging a torque sensor having sensing coils on a stationary portion side member opposite to a circular torque sensing face formed on the circumference of the counter shaft connected to an output shaft. CONSTITUTION:Direct shape magnetic anisotropy is provided on the outer circumference or the inner circumference of a counter shaft 13a which is a final out stage connected to an output shaft to form a torque sensing face 20A. The magnetic permeability change of the torque sensing face 20A by tensile force or compressive force based on a torque acting on the torque sensing face 20A is detected by the flat sensing coils 34A, 34B of a torque sensor 20B which is arranged at cylindrical portion 1a of a transmission case opposite to the torque sensing face 20A. Thus, the output torque transmitted to the counter shaft 13a can be detected directly and accurately so that the use of this torque sensing value can remarkably improve the control accuracy of a speed change controller which restrains a speed change shock.

摘要： PURPOSE:To correctly detect shock caused by shifting by forming a torque detection face of shape-magnetic-anisotropy on the rear side of the final stage fastening element of an output shaft, and providing a torque detection device on a cylindrical member on the transmission side opposing thereto. CONSTITUTION:In the rear side of the final stage fastening element of an automatic transmission, on the outer peripheral face of an output shaft 17, first and second group lines 32A, 32B which have shape-magnetic-anisotropy, are deformed in their shapes by tension and have increased magnet transmission rate namely have positive magnetic distortion characteristic. To a cylindrical member 20 on a transmission case side opposed to the lines 32A, 32B, a torque detector 30B having a detection coil is fitted. When the first and second group lines 32A, 32B of a torque detection face 30A receive tension or compression caused by fluctuation of torque of the output shaft 17, the rate changes and then it is detected by the torque detector 30B. It is thus possible to detect torque fluctuation of shifting shock and the like, in a non-contact condition and good responsiveness and to enable desirable shift control.

摘要： PURPOSE:To improve torque detecting accuracy, by fixing and arranging first and second coils, which can form magnetic circuits between first and second torque detecting surfaces at positions closely facing first and second grooves, which are set at a positive or negative slant angle with respect to the axial direction, separately. CONSTITUTION:Under the state torque is not applied to a shaft 1, an AC power source 32 for a measuring part 2B is turned ON. When AC is supplied to first and second coils 13A and 13B, magnetic circuits as shown by dotted lines are formed. When the magnetic circuit associated with the first coil 13A is noted, magnetic flux phi goes through a path formed by a first yoke 14A, a gap, a first torque detecting surface 16A and the first yoke 14A, a gap, a first torque detecting surface 16A and the first yoke 14A again. This is true for the magnetic circuit associated with the second coil 13B. A shaft 1 is rotated with a driving means. When torque is applied kin the direction R, the output voltage at output terminals d-b becomes higher than the voltage at output terminals c-b in a bridge circuit 30 in the measuring part 2B. In a signal processing part 34, the output of a rectifier circuit 38B is larger than the output of a circuit 38A. An indicator 36 indicates a specified negative voltage value.

摘要： PURPOSE:To permit the optimum connection operation corresponding to the state variation such as the variations of operation state and oil temperature by supplying the oil-pressure which varies from the proper connection starting oil-pressure to the perfect connection oil-pressure into a frictional elements for the connection when speed change is carried out. CONSTITUTION:A controller 50 obtains the connection starting oil-pressure which is optimum at that time point on the basis of the input signals related to a variety of operation and traveling states and outputs a control signal S3 into a pressure control valve 30 so that the connection starting oil-pressure is formed. Therefore, the output oil-pressure of the pressure control valve 30 lowers to the connection starting oil-pressure from the perfect connection oil- pressure, and when the output oil-pressure of the pressure control valve 30 is stabilized at the connection starting oil-pressure, the controller 50 revolves a rotary valve 60, and an output port 61b in closed state is opened to gradually increase the output oil-pressure of the pressure control valve 30 to the perfect connection oil-pressure from the connection starting pressure.

摘要： PURPOSE:To surely prevent creep on a road inclusive of an up grade, by provid ing a vehicle stop condition detecting means for detecting stop conditions of a vehicle, and changing an applied transmission range according to the stop conditions detected so as to match a creep torque with a required value. CONSTITUTION:First to third transmission ranges are automatically selected by switching on and off 1-2 and 2-3 shift solenoids 10 and 11 in combination, and these solenoids 10 and 11 are controlled by a controller 12. The controller 12 receives output signals from a range switch 13 adapted to be turned on in a drive range of an automatic transmission, an idle switch 14 adapted to be turned on upon undepression of an accelerator pedal, a vehicle speed sensor 15, a grade sensor 17, an inter-vehicle distance sensor 18 and a select switch 19 for commanding a maximum, medium and minimum level of a desired creep torque. Upon stoppage of the vehicle, an applied transmission range is changed according to an inter-vehicle distance and a grade to control the creep torque.

摘要： PURPOSE:To enhance effectiveness of engine brake and improve charging efficiency to an alternator, by controlling an auxiliary machine to an increased speed side irrespective of load condition of the auxiliary machine when a vehicle is driven with a reduced speed not less than a predermined value. CONSTITUTION:When an engine rotational speed obtained in a control unit 50 from an ignition pulse signal 51 is not less than a predetermined value during running of a vehicle, a pulley 6 is idly driven by not exciting a rotating coil 10, and auxiliary machines 2-4 are driven with a reduced speed by driving a pulley 11 through a one-way clutch 12. On the other hand, when the engine rotational speed is less than the predetermined value, the auxiliary machines 2-4 are driven with an increased speed by exciting the rotating coil 10 and rotating the pulley 6 integrally with a crank shaft 5 of an engine 1. When a reduced speed condition is detected from an output from a throttle opening sensor 56, the rotating coil 10 is excited irrespective of load condition of the auxiliary machines 2-4 to drive the auxiliary machines 2-4 with an increased speed.
