摘要： A power supply diagnostic circuit includes a switching power supply that generates a voltage for powering a fuel injector. An injector control module selectively applies the voltage to the fuel injector and monitors a resultant electrical current flow through the fuel injector. The switching power supply includes a dual path circuit comprising two inductors, two MOSFETs, and two diodes. The injector control module determines whether one path of the dual path circuit is defective based on the electrical current flow.

摘要： A load driving device including a converter, an output circuit and a timer circuit is provided. The converter receives a communication frame including a data signal through a serial communication and performs parallel conversion on the data signal to output an instruction signal instructing the output circuit to transition to a first state when the data signal includes first serial data and output an instruction signal instructing the output circuit to transition to a second state when the data signal includes second serial data. A timer circuit measures a duration time during which the converter receives the first serial data. When the measuring duration time arrives at an abnormality determination time, the timer circuit forces the output circuit to transition to the second state when the measuring duration time arrives at an abnormality determination time.

摘要： A control system for a variable valve timing apparatus that changes a valve timing of an internal combustion engine using a motor which is controlled by operating a switching element includes: an oil temperature estimating portion; a substrate temperature estimating portion; and a current limit controller. The oil temperature estimating portion estimates a temperature of lubricating oil of the engine. The substrate temperature estimating portion estimates a temperature of a substrate to which the switching element is mounted based on the temperature of the lubricating oil. The current limit controller limits a current flowing through the switching element based on the temperature of the substrate in a manner that a temperature of the switching element is restricted from exceeding a predetermined upper limit value.

摘要： In an internal combustion engine controller, a clock trouble determination signal from a clock trouble determining circuit that diagnoses any clock input trouble is transmitted in parallel with an abnormality diagnosis signal outputted from an abnormality diagnosing circuit and causes it to be inputted to a trouble/abnormality signal output circuit, and the trouble/abnormality signal output circuit achieves logical summing to output one line of resultant trouble/abnormality output OR signals to a microprocessor (MP). The MP outputs to the trouble/abnormality signal output circuit a trouble/abnormality confirmation input signal, and makes definite any of an abnormal state, a clock trouble state and a normal state based on the result of switching control of the status level of the pertinent trouble/abnormality output OR signal.

摘要： An engine fuel delivery system, prognosis system, and method of conducting a fuel pump solenoid prognosis are provided. The engine fuel delivery system includes a fuel pump having a pumping chamber, a closeable inlet valve (such as a fuel pump control solenoid), and a fuel rail to communicate pressurized fuel received from the fuel pump to at least one engine cylinder. The engine fuel delivery system, prognosis system, and method are configured to determine a solenoid current feedback of a fuel pump control solenoid and a variation in the feedback. The fuel delivery system, prognosis system, and method are further configured to indicate a potential solenoid electrical connection fault if the solenoid current feedback is less than a predetermined current threshold and less than a predetermined variation threshold, and to indicate a potential solenoid weakened electromagnetic field fault if the solenoid current feedback is greater than the predetermined variation threshold.

The converter receives a communication frame including a data signal through a serial communication and performs parallel conversion on the data signal to output an instruction signal instructing the output circuit to transition to a first state when the data signal includes first serial data and output an instruction signal instructing the output circuit to transition to a second state when the data signal includes second serial data.

When the measuring duration time arrives at an abnormality determination time, the timer circuit forces the output circuit to transition to the second state when the measuring duration time arrives at an abnormality determination time.
