摘要： A fail-safe system for an engine control system is capable of performing a fail-safe operation when a crank angle sensor fails. When the crank angle sensor malfunctions, at least one of a crank reference signal and a crank position signal will be absent. The fail-safe system prevents the engine from stalling even when one of the crank reference signal and the crank position signal is absent. The fail-safe operation will be carried out when the absence of the crank reference signal and/or the crank position signal is detected. In the fail-safe operation, a fail-safe signal is produced for controlling engine operation as a replacement for an engine control signal from the engine control system under normal conditions. The signal value of the fail-safe signal may be variable in accordance with an engine operating condition derived from an engine control parameter other than the crank angle sensor signals.

摘要： A digital control system for an internal combustion engine uses a two stage register. The register is used to store digital data representative of sensed engine operating conditions and to feed such data to a programmable digital computer for processing. Processing time is improved by reading only one register containing the most significant data bits of the stored data for engine parameters having a relatively narrow dynamic range and reading both registers, containing all data bits of the stored data for engine parameters having a relatively large dynamic range.

摘要： A fault diagnostic system is arranged to detect faults in a fuel system of an engine with an electronic fuel injection system by monitoring the quantities of fuel consumed during a time interval. To do this, the consumption quantity of fuel is determined from a decrease of the residual quantity of fuel remaining in a fuel tank which is detected by a fuel gauge. On the other hand, the fuel injection quantity is determined independently by summing the length of the injector open time of each injection. Then, the fuel consumption quantity and the fuel injection quantity during the same time interval are compared. If the difference therebetween is larger than a predetermined permissible range, it is decided that there is some fault somewhere in the fuel system, and an indication signals is produced.

摘要： A self-monitoring system for an automotive electronc control system such as an engine control system, an electronic anti-skid control system or electronic automatic transmission control system is adapted to check each segment of the electronic control system in order to detect faulty segments. To detect faulty segments, the self-monitor system checks inputs and outputs of the electronic control system. The checked data is stored in a memory which is not erased when the power supply is turned off. The self-monitoring system is associated with another automotive microcomputer which includes a display unit. The other automotive microcomputer is adapted to display the results of the checking operation of the self-monitoring system in response to a display request manually inputted from a manual unit to display identification of the fault segment and/or error condition thereof. The monitor can also be associated with a fault indicator, such as an LED, which is responsive to detection of error in any of the segments to turn on.

摘要： In an engine speed sensing device, angle pulses produced when the crankshaft rotates through a predetermined angle are counted by a counter for a predetermined interval. The count of angle pulses is read into a central processing unit of a digital computer at the end of each set time interval in response to a control signal which both updates the angle pulse count and signals the processing unit to read the count.

摘要： A highly reliable, fail-safe circuit for a control system wherein a controlled device will always receive a control signal derived from a main control circuit when the main control circuit operates normally even if a back-up control circuit backing up at least one function of the main control circuit which is a minimum requirement for an operation of the controlled device fails or wherein a controlled device will receive a control signal derived from the back-up control circuit when the main control circuit fails. Replacement of the control signal from the main control circuit with a back-up control signal from the back-up circuit is carried out only when the back-up circuit outputs a particular signal at or near a predetermined frequency or alternatively when the back-up circuit outputs a plurality of parallel logical signals in a predetermined combination.

摘要： A method and apparatus for controlling fuel to be supplied from a motor-driven fuel pump to fuel injection valves of a fuel injected engine, the time period during which the fuel injection valves are kept open and the power duty cycle for driving the fuel pump motor are both calculated by a microcomputer responsive to one or more engine operating conditions. Reduced power consumption of the pump motor is achieved, thus resulting in reduction in the load applied to the battery and therefore improving the fuel consumption rate. The apparatus comprises an input unit, an injector drive unit, and a pump drive unit in addition to the microcomputer, and includes circuits for converting both the time period and the power duty cycle according to the battery voltage and the degree of engine acceleration.

摘要： An ignition energy control method and system such that a high ignition energy is supplied to the spark plugs only while the engine is operating under an unstable condition. The unstable engine operating condition is determined by detecting the difference in the maximum engine speed within a predetermined crankshaft revolution angle or by detecting the low-frequency vibration generated by the engine. The ignition energy is controlled by calculating an appropriate pulse-width of an ignition signal or by changing a high voltage generating plasma within the cylinders. The ignition energy control system according to the present invention comprises a crankshaft angle sensor or a low-frequency vibration sensor, a calculating and storing means, and an ignition system including a plasma generating power supply where necessary.
