    摘要: A control device with a time measuring function measures a turned-off time of an ignition switch with a low consumption current and high accuracy at a level adapted for a demand from the controlling side, as well as a turned-on time of the ignition switch. The control device also measures an accumulative turned-on time of the ignition switch. The control device comprises a battery, a microcomputer for computing a control variable to control a control target, a time measuring unit, a clock source for the microcomputer, a clock source for the time measuring unit, and a unit for changing over operation of the time measuring unit depending on an intended use. The time measuring unit operates regardless of run/stop of the microcomputer.

    摘要: The object of the invention is to provide a low-priced engine control apparatus having a single CPU configuration which can be used for knocking detection and engine control as well, including: an A/D conversion unit which samples, at a predetermined cycle, analog signals of knocking detected and output from a knock sensor; an A/D converter for converting a sampled analog signal to a digital signal in a predetermined conversion time per A/D conversion; a frequency analysis unit which analyzes digital signals upon A/D conversion; a knocking judgment unit which judges the presence of knocking on the basis of a result of the frequency analysis; and a CPU which includes an ignition timing arithmetic unit which executes arithmetic calculation for controlling ignition timing corresponding to knocking on the basis of the judgment so as to ensure an optimum engine control in response to knocking. The predetermined cycle in A/D conversion unit is defined by a period of time which allows for the A/D converter to execute A/D conversion N times, with N being an integer greater than or equal to 2.

    摘要: A first sensor element outputs a first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A second sensor element outputs a second output signal associated with the first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A first conversion processing section converts the first output signal output from the first sensor element and the second output signal output from the second sensor element into the second physical quantity. A second conversion processing section converts the first output signal output from the first sensor element and the second output signal output from the second sensor element into a signal representing the rotation angle of the motor.
