摘要： A method for controlling a plurality of injectors installed in the same cylinder of an engine may include determining whether an electrical failure occurred in any of the injectors, and entering a fail-safe mode when an electrical failure has occurred only in one of the plurality of injectors in the same cylinder. In the fail-safe mode, fuel supply to an injector that has experienced an electrical failure is cut off, and the amount of fuel injected into the cylinder by a normally operating injector is increased.

摘要： A controller of an air-fuel-ratio sensor includes a control unit, a voltage-abnormality detecting unit, and a short-circuit-abnormality detecting unit. The control unit controls a current and a voltage of a gas sensor element through a plurality of terminals connected with the gas sensor element. The voltage-abnormality detecting unit changes, when at least one of voltages of the plurality of terminals is out of a predetermined range, a voltage level of an output voltage. The short-circuit-abnormality detecting unit causes, when the voltage level of the output voltage changes from a first voltage into a second voltage, a control unit to perform for a predetermined time a protective operation that suppresses currents from the control unit to the plurality of terminals, and detects, when the voltage level of the output voltage is the second voltage after the protective operation is released, a short-circuit abnormality.

摘要： The invention relates to a method for determining a characteristic value of a magnetic switch valve. The magnetic switch valve can be switched from a closed switch state into an open switch state, via the movement of a rotor by means of a switching magnet applied with current against a conservative restoring force. According to the invention, during the switching of the switch valve from the open state into the closed state, the time course of the current flowing through the switching magnet and/or of the voltage at the switching magnet is measured. The characteristic value to be measured is evaluated from this time course. It was recognised that every movement of the rotor against the switching magnet induced a voltage in same. Now the voltage at the switching magnet is regulated at a constant value, for one, the voltage induced by the movement can be observed as a control deviation in the short term. For another, the induced voltage causes a current flow through the switching magnets. Based on this, the kinematics of the rotor can be deduced. Given that the switching magnet has an ohmic resistance, energy is also dissipated via the current flow. This energy is the key to determining the switching path covered by the rotor when switching between the closed and the open state. The invention also relates to a measuring device that is particularly suitable for the method.

摘要： A method for preventing engine stall of a vehicle includes detecting, by a control portion, whether a purge control valve becomes short to ground or not, determining, by the control portion, how rich a fuel is that has flowed into the engine using an oxygen sensor when it is determined that the purge control valve becomes short to ground in the detecting step, and controlling, by the control portion, a target RPM of the engine to be increased when it is determined that the fuel is rich in the determining step.

摘要： An electronic control device having an input processing circuit capable of arbitrarily connecting one or both of a pull-up resistor and a pull-down resistor to an input signal from outside and capable of arbitrarily setting a resistance value of the pull-up resistor and/or the pull-down resistor connected, to diagnose whether the resistance value of the pull-up/pull-down resistor is a designed value. The input processing circuit has a unit that diagnoses whether the resistance value of the pull-up resistor and/or the pull-down resistor is within an expected range. The pull-down resistor is connected to the pull-up resistor when the resistance value of the pull-up resistor is to be diagnosed, the pull-up resistor is connected to the pull-down resistor when the resistance value of the pull-down resistor is to be diagnosed, and the resistance value is diagnosed based on the voltage divided by both the pull-up resistor and the pull-down resistor.

摘要： A method of detecting a resistive short-to-ground fault in an injector driver circuit is disclosed. The method includes determining if the injector driver circuit is in an inactive state and providing a pull-up resistor configured for connection to a low-side output of at least one fuel injector. The method further includes selectively enabling a pull-up voltage across the pull-up resistor only when the injector driver circuit is in the inactive state and determining an intersection voltage at a point between the pull-up resistor and the low-side output. The method further includes comparing the intersection voltage with a predetermined reference voltage. The method further includes disabling the injector driver circuit if the short-to-ground fault is detected at the low-side of the fuel injectors.

摘要： A method performs a diagnosis of a lambda sensor of a “UEGO” type of an exhaust system for an internal-combustion engine. The lambda sensor includes a series of pins. The diagnosis method comprises steps of: heating the lambda sensor to cause the lambda sensor to reach an inner temperature that is higher than about 600° C.; polarizing a first one of the pins by connecting the first pin to a supply voltage through a first limiting resistance; measuring a voltage of all of the pins while the first pin is connected to the supply voltage; and diagnosing a presence of a short circuit to an electrical ground if the voltage of at least one of the pins is lower than a predetermined threshold. A control unit performs the diagnosis.
