Abstract: The invention, while reducing noise, suppresses a load increase in a processor and a delay in drive control. An engine control unit includes a processor, a driving circuit including a switching element to drive a load such as a fuel injector and an ignition device, and a communication circuit that transmits control signals from the processor to the driving circuit via serial communication. The control signals each include a command frame for controlling the driving circuit and a data frame for driving the load. If a predetermined bits in each of the data frames received from the processor at predetermined time intervals are determined to be the same twice in succession, the engine control unit changes a state of a driving signal ‘Drive’ for driving the load and thereby changes an operating state of the switching element.

A capacitor and an impedance element are arranged in series on the connecting line connecting the positive electrode line and the negative electrode line of a DC power supply, the connecting line between the capacitor and the impedance element is connected to one end of a magnet coil via a freewheeling diode, and the portion between the freewheeling diode and the one end of the magnet coil is connected to the positive electrode line or the negative electrode line by a switching element. Conduction noise caused by the driving current of the magnet coil can be suppressed by the impedance element, and the capacitance of the capacitor can be further reduced. Accordingly, the magnet coil drive control device can be made smaller in size.

The phase detection circuit comprises a multiplier for multiplying an input signal by a reference signal and outputting a first signal, an integration circuit for integrating the first signal and outputting a second signal, a phase estimation circuit for estimating phase information based on the second signal, and a reference signal generation circuit for generating the reference signal based on the estimated phase information. Since the phase is detected based on information representing an entire waveform, the influence of local noise can be diluted and noise immunity can be improved.
