摘要： PURPOSE:To attain detection with high accuracy, without complicated software, by transmitting an output the polarity of which is inverted at each period of a diagnostic pulse applied externally from a specific output port, monitoring and detecting this operation through the relation to the diagnostic pulse. CONSTITUTION:Normally, a CPU2 has a runaway monitor program and inverts the polarity of an output signal B during the priod of a pulse A. An inversion detection circuit 3 transmits a pulse signal C at the leading and trailing of the signal B. Further, an FF7 is set when the signal A falls down, an output signal is reset at each input of the signal C and an output D is as shown in Figure (d). The signal D is not coincident with the signal A when the CPU2 is normal, signals E, F go to ''L'' to avoid the fail control and the reset of the CPU2. If the CPU2 runs away and the signal B keeps H, the signal C is not transmitted, the signal D goes to ''H'', the coincidence with the signal A is taken, the signal E is generated, a monostable multivibrator 9 is operative, a signal F with the specified pulse width is generated for the fail control and the CPU2 is set.

摘要： PURPOSE:To detect a runaway easily without adding complicate interval processing to the control flow of a microcomputer. CONSTITUTION:While a microcomputer 6 is normal, an output signal B inverted in polarity at intervals less than a predetermined period is generated at its output port P2 invariably, and an integral output obtained through an inversion detecting circuit 7 and an interpulse integrating circuit 11 never reaches the threshold level Vth of a level comparator 16. Once the microcomputer 6 enters into a runaway state, runaway monitoring software interrupts the inversion of the output signal generated at the output port P2, and then the output D of the interpulse integrating circuit 11 rises above the Vth to trigger a monostable multivibrator 17, which generates an output F to perform fail-safe control and also to reset the microcomputer 6.

摘要： PURPOSE:To make it possible to prevent transistors and the like in an engine ignition control unit from being failed, by specifying inputs to a switching element for controlling the energization of an ignition coil in dependence upon the informaton which is obtained from the detected output state of an ignition control signal generating circuit 5. CONSTITUTION:When a crank shaft 20 is rotated during engine operation, the voltage S4 of a capacitor C1 is low level, the inverted signal S5 of an inverter is high level, the ignition signal S6 from an AND gate is identical with the ignition control signal S3, and a transistor 7 is at high level, thereby ignition is performed. When the engine is stopped, no crank angle pulses S2 are delivered to an ignition control circuit 5, and therefore, the signal S3 therefrom is maintained at high level so that the signal S4 exceeds the threshold level of the inverter IN, resulting in the signal S5 being inverted. At this time, the igntion control signal S6 is low level and the transistor 7 is turned off for discontinuing the unnecessary energization of an ignition coil 8 in association with engine stop, thereby the failure of the transistor and the ignition coil are prevented.

摘要： PURPOSE:To perform the backup reliably by producing the simulated firing signal relative to the referential position signal while driving the firing coil utilizing the simulated firing pulse when the crank angle sensor signal is interrupted. CONSTITUTION:Upon the interruption of the crank angle pulse KP, the signal to the counter 15 is eliminated to stop the counting. Consequently the Q6 output is brought to L while the output from the inverter 19 is brought to H and the AND gate 20 will feed the reset signal S to FF circuit 22 for every referential position pulses KP1, KP2. While since the delay output from the delay circuit 18 is maintained in L, the rest signal R from the AND gate 21 to FF circuit 22 will be maintained L. Consequently FF circuit 22 is set continuously by the set signal S for every production of the referential position pulses RP1, RP2, thereby the set output Q is brought to H thus to produce the abnormality detection signal G. Upon said signal G, the data selector 23 will select the simulated firing signals A', B' from FF circuit 12 and to switch thus to perform the backup.

摘要： PURPOSE:To detect an incremental position of a pulse motor in a rotating direction as an electric signal capable of being digitally processed by converting multiphase drive pulses from a drive circuit of the motor into binary signals corresponding to the increments of the rotary shaft. CONSTITUTION:A plurality of multiphase drive pulses from the drive circuit 2 of a pulse motor 1 are converted into binary signals corresponding to the increments of the rotary shaft of the motor to generate the binary signal at every increment of the rotary shaft. For instance, 4-phase drive pulse from the output of the drive circuit 2 is converter by a decoder 4 into binary digital signal, which is branched in response to the energizing system by the converting circuit 5. This output is held in a holding circuit 7 through a waveform shaper 6, discriminated in forward or reverse by discriminators 8, 9, and the outputs are further outputted through a memory circuit 10 to output terminals 11, 12.

摘要： PURPOSE:To generate the rotary angle pulse having a unit angle smaller than equally spaced angle of rotary angle reference bodies, by detecting the passage of the rotary angle reference bodies equally spaced around the outer surface of the rotary body, counting the number of high speed clock pulses at every period of the generated sensor signal, and generating the rotary angle pulse every time the high speed clock pulses are counted by the number which agrees with the value that is 1/N the counted value. CONSTITUTION:When the rotary body 1 is rotated in association with the rotation of a body whose rotation is to be detected, a sensor 3 detects the passage of tooth parts 2 and generates the output. A counter 7 counts the number of the clock pulse in every period of the sensor signal A and outputs the result. A latch circuit 8 divides the counted value Y of the pulse phi by using an expression 1/2n=1/N and accepts the result. A down counter 9 performs the down cout every time the pulse phi is supplied. When the counted value reaches a preset value, the rotary angle pulse D is generated from an output terminal OUT. The rotary angle pulse D whose frequency is multiplied by N=2n times, is outputted. Therefore the unit angle is made smaller to 1/N=1/2n in comparison with the conventional angle.

摘要： PURPOSE:To attain detection with high accuracy without complicated software, by monitoring the output of a specific output port once at one period of an external diagnostic pulse, and performing the specified control with a plurality of inversions. CONSTITUTION:Normally, a CPU2 has a runaway monitoring program, and the polarity of an output signal B is inverted once during the period of a diagnostic pulse A. An inversion detection circuit 3 transmits a signal C at the point of change of the signal B and an output of an FF7 is as shown in Figure (d). A signal D is discident with the signal C, an output E keeps ''L'', and a signal F does not perform fail control and reset the CPU2. When the CPU2 runs away and the signal B is inverted twice during one period of the signal A, a signal C is generated from a gate 6, it is coincident with the output of the FF7, a signal E is generated and a monostable multivibrator 9 is set. A pulse F of a prescribed width is generated, the control is switched to fail control and the CPU2 is reset.

摘要： PURPOSE:To make it possible to prevent engine operating failure by providing a signal processing circuit for delivering false pulses as an ignition control signal when either one of first and second reference position pulses is disappeared. CONSTITUTION:Transistors TR1, TR2 are turned of and off, respectively, by ignition control signals S14, S15 due to reference position pulses S7, S8 so that ignition plugs #1, #4 and the ignition #3, #2 are ignited, alternately. Estimating that the pulses S7 are not delivered, caused by the breaking of wire in a magnetic sensor SN1, since the ignition control signal S15 sets a flip-flap circuit 16 in this case, the output signal S18 of the flip-flap circuit 16 is at high level but the inverted signal S19 is at low level so that a counter 7 counts crank angle pulses. However, a signal S10 becomes rectangular pulses, since the counter 7 is not reset, so that a differential signal S11 during the rise time of the rectangular signal is delivered from a circuit 9, and a signal S12 is delivered from an AND circuit 10 since both signals S11, S18 are at high level, thereby the ignition control signal S14 is delivered without disappearing.
