TL;DR: In this article, an electrical control unit for an automobile having a microcomputer, an input circuit, a driver circuit, and a power supply circuit, which is started by a wake-up signal from a circuit other than the ignition switch, is described.

TL;DR: In this article, an exciting signal generator is used to generate a conversion trigger signal from the exciting signal generated from a signal generator and an A/D converter that converts the resolver signals produced from the signal generator to digital values in response to the conversion trigger signals generated from the generator.

TL;DR: In this article, a motor control system consisting of a switch circuit for supplying a driving current to a motor, a resistor for detecting the driving current, an amplification circuit for amplifying a potential difference across the resistor, an input section switch unit disposed in an output section of the amplification circuit and changing over the potential difference to be forward biased or reverse biased.

TL;DR: In this article, a control apparatus for controlling multiple power loads in a vehicle includes a circuit for detecting a current abnormality of a power element and another circuit for monitoring a temperature abnormality in a locality of the power element, with a timing established according to a substantially constant period or a time interval which is stored in advance in a memory element.

TL;DR: In this paper, a controller for an internal combustion engine having a fuel injection system with a solenoid comprising of a means for detecting an operating condition of the engine, a means of calculating the fuel injection pulse width according to the detected operation condition, and a means to switch between different current waveforms according to detected operating condition.
