摘要： A device for detecting the difference in the rotary speeds of two rotating shafts comprises a bearing for coaxially mounting the shafts for rotation in opposite directions, a low power precision stepping motor imparting a programmed speed of rotation to one of the shafts, a gearing interconnecting the shafts and displaceable in response to a change in the relative angular position of the two rotation shafts, and a sensor detecting displacement of the gearing in response to the change.

摘要： When an automatic transmission shift start condition is satisfied, an electronic control unit calculates a meter target rotational speed of an engine by adding a correction amount corresponding to the state of a torque converter to a turbine rotational speed corresponding to a post-shift gear stage, and makes a meter display rotational speed follow after the meter target rotational speed, fixes the correction amount to a value obtained at the time of shift start determination, when immobilization conditions including that the shift start condition for a downshift is satisfied and that the engine is driven are satisfied. When actual rotational speed display conditions are satisfied, it can be predicted that differences between an engine rotational speed and a turbine rotational speed before and after shifting are large, and so the electronic control unit sets a current engine rotational speed as the meter target rotational speed or ends the control.

摘要： Since a maximum rotation speed of a second rotary machine is set to a lower value when a supercharging pressure is high than when the supercharging pressure is low, an engine torque decreases with an rotation speed of the second rotary machine which is relatively low and the rotation speed is less likely to fall into a high-rotation state. When the supercharging pressure is relatively low and the rotation speed is less likely to reach an upper-limit rotation speed of the second rotary machine, the maximum rotation speed is set to a relatively high value. Accordingly, the engine torque does not decrease to the rotation speed which is relatively high and power performance can be easily secured. As a result, it is possible to prevent a decrease in power performance due to the decrease in the engine torque and to prevent the rotation speed from falling into a high-rotation state.

摘要： An encoder includes a code disc and a processor communicatively coupled with the code disc. The code disc is configured to rotate along with a rotating object and includes a plurality of fan teeth extending radially. Each of the fan teeth includes a first line segment edge, a second line segment edge, and an arc edge along a circumference of the code disc and connecting the first line segment edge and the second line segment edge. The first line segment edges of the fan teeth are arranged at the code disc with equal intervals. A length of the arc edge of one of the fan teeth is different from lengths of the arc edges of other ones of the fan teeth, and the lengths of the arc edges of the other ones of the fan teeth equal each other. The processor is configured to detect a rotation of the code disc to obtain a detection signal, and obtain a rotation parameter of the rotating object based on the detection signal. The rotation parameter includes at least one of a rotation direction, a rotation speed, or a mechanical zero position.

摘要： An actuation device for a tachometer adapted to transmit the revolutions of an engine crankshaft to the tachometer, wherein the oil pump of the engine is utilized as a speed reducing mechanism for transmitting the revolutions of the engine crankshaft to the tachometer after the engine speed is reduced. A cable connected at one end to the plunger of the oil pump whose speed is reduced by means of a gearing is connected at the other end to the tachometer. Thus, by utilizing the oil pump, it is possible to transmit the revolutions of the engine crankshaft to the tachometer without requiring a speed reducing mechanism provided exclusively for the tachometer.
