摘要： In a method for measuring variations in the output of an internal combustion engine, at least one of signals respectively representing an engine speed, torque, and internal cylinder pressure of the internal combustion engine during the firing strokes of the engine is obtained. A periodical and pulsating change in the obtained signal is detected. A differential value at a portion of the change of the signal having a maximum gradient is then detected. Another method provides measuring variations in the output of the internal combustion engine by calculating the difference between the maximum and minimum values of the change of the obtained signal. Still another method provides measuring variations in the output of the internal combustion engine by correcting the obtained value in accordance with the engine speed. Still another method provides measuring variations in the output of the internal combustion engine by calculating the difference between consecutive changes.

摘要： A torque detector, particularly a torque detector for detecting a torque applied to a torque transmission shaft which is connected to a load such as a wheel of an automobile, comprises a first shaft connected to a driving shaft, a second shaft connected to a torque transmission shaft, and a plurality of elastic members, each of which is interposed between the first shaft and the second shaft for transmitting the torque of the first shaft to the second shaft while receiving the compression force between the first shaft and the second shaft when the driving shaft is driven. The first shaft comprises a flange portion wherein a plurality of long grooves are formed so as to extend in the rotating direction thereof. The second shaft comprises a flange portion wherein a plurality of long holes are formed so as to extend in the rotating direction thereof and penetrate therethrough at such positions as to be substantially opposed to said long grooves. Each of the elastic members is accommodated within each of the long holes. The projecting side portion of each of the elastic members is accommodated within each of the long grooves. The long holes are grouped into two kinds of long holes having different lengths in the rotating direction of the second shaft. One kind of long holes have a length equal to that of the long groove of the first shaft while the other kind of long holes have a length longer than that of one kind of long holes by a predetermined angular distance. Until the applied torque reaches a predetermined value, the first shaft is connected to the second shaft only through one kind of elastic members to decrease the total spring constant thereof and when the applied torque exceeds the predetermined value, the first shaft is connected to the second shaft through all of the elastic members to increase the total spring constant thereof. The torque detector further comprises a data processor by which the angular phase difference between the first shaft and the second shaft, which occurs due to the compression of the elastic members is detected and torque is calculated from the detected angular phase difference.

摘要： An electronically controlled ignition system for internal combustion engines. Reference position detecting means generates reference signals and angular position detecting means generates angular signals indicative of the angular positions of an engine at every predetermined angle of its rotation. Computing means responsive to engine operating condition parameters computers a proper ignition coil energization starting timing data and a proper ignition coil de-energizing timing data. An ignition coil control circuit comprising latch circuits, comparator circuits and counting means converts the ignition coil energization starting timing data and the ignition coil de-energization timing data into pulses having a corresponding pulse width with respect to the rotational angle of the engine to supply an ignition coil energization starting timing signal and an ignition coil de-energizing timing signal to said ignition coil. The computations of the energization starting timing and de-energization timing are initiated in response to the reference signal and the energization starting timing signal, respectively, so that the energization starting timing data is computed by using the de-energization timing data computed in the preceding computation cycle and that the ignition coil control circuit is simplified in circuit construction.

摘要： A road surface detecting device has a rotary sensor for detecting the passage of teeth formed in an outer surface of a circular plate at regular intervals, which is connected to an axle of a vehicle and rotates thereabout, and generates an output signal pulsing every time when said teeth pass the rotary sensor. The output signal is inputted to a microcomputer. The microcomputer calculates period variations of the pulsing output signal and an average value of a predetermined number of the period variations. When the average value is not less than a predetermined value, the road surface is determined as being in a bad condition and when the average value is less than the predetermined value, the road surface is determined as being in a good condition; when the average value is less than the predetermined value and the most recently calculating period variation is not less than a predetermined period variation, the road surface is determined as being a rough area on a good road.

摘要： A torque variation in an internal combustion engine due to the combustion variations is detected at each predetermined period. An average torque variation to be compared with the detected torque variation is predetermined experimentally based on the engine speed and the intake manifold pressure and is stored in a memory. The number of the detected torque variations which exceed the average torque variation multiplied by a predetermined constant is counted, and if the ratio of the counted number to the total number of the detected torque variations is larger than a predetermined reference value, then the presence of a torque variation is determined.
