摘要： PROBLEM TO BE SOLVED: To provide a misfire detecting device capable of detecting the misfire of an internal combustion engine on the basis of the ion current, detecting the deterioration of the insulating characteristic of an ignition plug, and detecting the misfire with high accuracy without being affected by the leaked current in a deteriorated period of the insulating properties of the ignition plug. SOLUTION: A voltage is applied for the ignition and the combustion of the air-fuel mixture at a first predetermined crank angle θig1 to generate the spark discharge on an electrode of the ignition plug 24 to ignite and combust the air-fuel mixture. The ion current generated at that time is detected and compared with a predetermined value to determine whether the misfire occurs or not (S22-S26). At a second predetermined crank angle θig2 different from the first predetermined crank angle θig1, a voltage is applied for the plug test (test of insulating properties), and the leaked current at the time is detected and compared with a predetermined value to determine whether the insulating properties of the ignition plug 24 is deteriorated or not (S28-S34).

CONSTITUTION:In an electronic control device 5 for an engine, both a CPU 51 for fuel control use for controlling a fuel injection device 22 and a CPU 52 for throttle valve control use for controlling a pulse motor 31 by which an intake throttle valve is driven so as to be opened or closed are arranged respectively, and these CPUs are connected to each other by a bus bar 53. On the basis of the detection signal from an accelerator sensor 4, the opening signal of the pulse motor 31 is calculated by the fuel control CPU 51, and also the opening signal for alternate use is calculated by the throttle valve control CPU 52. Thereafter, when an abnormality is caused in the fuel control CPU 51 itself or in the storing part 54 for storing opening signal therefrom, the opening signal for alternate use is output from the throttle valve control CPU 52 to the pulse motor 31.

摘要： PROBLEM TO BE SOLVED: To provide an on-vehicle gateway apparatus capable of transferring data between networks following priority more faithfully, while suppressing the number of transmission message boxes. SOLUTION: The number of a plurality of transmission message boxes to be configured is smaller than the number of identifiers attached to data. When data having the same identifier as new data is stored in any of the plurality of transmission message boxes at the reception of the new data to be transferred, transmission to the other networks of data having the same identifier is stopped, and the data having the same identifier is overwritten with the new data for storage. When the data having the same identifier as the new data is stored in none of the transmission message boxes, data having priority lower than that of the new data and an identifier having the lowest priority is overwritten with the new data for storage out of data stored in the plurality of transmission message boxes.

摘要： PURPOSE:To judge a position of failure occurrence by outputting a driving signal to a step motor which drives a control mechanism for an engine intake amount or a fuel supply amount against an energizing force of a return spring which energizes the mechanism in a closing direction. CONSTITUTION:A throttle valve 31 which controls a sectional area of an intake passage 2 of an engine 1 is opened and closed by means of a step motor 3, while a spring 33 is provided for driving the throttle valve 31 in the closing direction at the stopping time of the step motor 3. Prior to execution of normal control of the step motor 3 by means of a controller 4, the throttle valve 31 is checked whether it is totally closed or not by means of an opening sensor 32. In the case that it is not totally closed, a returning driving signal of a rate corresponding to the totally closed condition is output to the step motor 3. When it is returned to the totally closed condition, failure occurrence at the spring 33 is judged. When it is not returned, failure occurrence at the step motor 3 is judged.

摘要： PURPOSE:To ensure enough drive torque even during a fluctuation in a source voltage by providing a means to vary the given period of a pulse, applied on the exciting phase of a step motor, to a long period when it is discriminated by a discriminating means that an exciting duty exceeds a given value. CONSTITUTION:Two drive modes of one being a two-phase drive mode and the other being a microstep mode are properly used by a step motor 15. The microstep mode is a drive method wherein drive currents of different duties are respectively fed to adjoining exciting phases. Further, a means to change an exciting duty of a pulse of a given period applied on the exciting phase of the step motor 15 and a means to discriminate whether the exciting duty exceeds a given value are provided. This constitution ensures enough drive torque even when a fluctuation in a source voltage is produced in a way that when the exciting duty exceeds a given value, a given period of a pulse applied on the exciting phase of the step motor 15 is varied to a long period.
