PURPOSE:To always supply a correct input signal to a CPU unit without being accompanied by a system-down even at the time of the abnormality of an input circuit by providing at least >=3 input circuits and selecting and outputting the data outputted from respective input circuits to an interface based on the principle of a majority determination. CONSTITUTION:Outputs A-C of respective input circuits 8A-8C are inputted through a switch circuit 11 to a majority circuit 12, selected based on the principle of a majority and outputted through an OR gate 13 to an interface 9. Consequently, for example, when the input circuit 8A breaks down and a normal signal is outputted from input circuits 8B and 8C, the majority circuit 12 compares the inputted data A-C, selects the most common data B and C and outputs them to a CPU unit 3. Thus, the signal from an external switch 6 can be correctly inputted to the CPU unit 3, and respective types of the sequence can be correctly satisfactorily controlled without being accompanied by the system-down.

PURPOSE:To attain proper guidance at the power ON of a system, by storing data related to the coordinates of a current position and the moving direction of a moving body at the power OFF of the system while updating the data in accordance with the moving status of the moving body. CONSTITUTION:The position of the moving body is found on the basis of outputs from a distance detector 2 and a direction detector/under the control of a signal processor 3 and its positional data are displayed on a display 7 together with a map image-picked up from a microfilm 5 by an image pickup device 6. The signal processor 3 detects the moving status of the moving body at the power OFF of the system by the complete explosion of an engine and stores data related to the coordinates of the current position and the moving direction in a volatile memory 19 in accordance with the detection while updating the data in accordance with the moving status of the moving body.

PURPOSE:To efficiently analyze the cause of an abnormality generation by recording and storing the transition of main servocontrol data before and after the abnormality generation of a servocontrol system under the control of a microcomputer into a RAM. CONSTITUTION:When the generation of the abnormality is detected by an abnormality generation detecting part 21 of a CPU 20, switches 13c and 13d are opened, the power of a driving system 10 is interrupted, a counter 25 is activated, the recording frequency of the data after the abnormality generation is counted, and whether the data recording in a prescribed frequency M is executed or not is decided. For respective servocontrol data after the abnormality generation, fluctuations are large, and while the recording frequency does not attain to the prescribed recording frequency M, the data of approximately each frame are recorded, and when the frequency attains to the prescribed M frequency, the recording of the data is stopped. Thus, to RAM 32, the cause of the abnormality generation can be efficiently analyzed by using the data left as the record of the servocontrol data before and after the abnormality generation.

PURPOSE:To highly accurately detect the position of digital rotation by installing a pair of Hall elements which detect the magnetic flux of a rotor made of permanent magnet at a phase difference of pi/2-interval to an armature core. CONSTITUTION:A rotation detector is constituted in such a way that Hall elements 10 and 11 which detect the magnetic flux of a rotor R made of permanent magnet are installed at a phase difference of pi/2-interval to an armature and, at the same time, sin generator 17 and cos generator 16 are connected to the current terminals 10i and 11i of the Hall elements 10 and 11, respectively, and a control circuit 12 which operates the output values of the voltage terminals 10v and 11v of the elements 10 and 11 and controls so that the operated value goes to zero, voltage controlling oscillator 13 which generates a pulse in accordance with the output value, counter 15, etc., are connected to the voltage terminals 10v and 11v. Since the control circuit 12 controls so that the difference in rotational angle, theta-theta', goes to zero, the angle of the rotor R becomes almost equal to the output value theta' of the counter 15 and a rotational position signal is easily obtained. Therefore, the position of digital rotation can be detected with high accuracy.

PURPOSE:To reduce the size of a recorder for a vehicle and to standardize the recorder by providing a correcting function for the difference of the diameters of wheels for the vehicle in a reproducer. CONSTITUTION:Speed and running information is recorded in a recorder. Information recorded in the recorder is inputted to an inter terminal 11 of a reproducer. A logic unit 13 serves to calculate the specified diameter of the wheel from a wheel diameter setting unit 14 and the corrected value from a corrected value setting unit 16, and to correct speed information recorded in advance from a programmed formula. The speed and running information thus corrected is outputted to a panel indicator 17 and a printer 18. In this manner, the recorder can be reduced in size and can also be standardized as well as reduced in carrying space on a vehicle.
