摘要： To sense proper operation of a servo control loop including a fuel control pedal (1) which operates a command control transducer (2), e.g. a potentiometer coupled thereto, to provide a command signal to a controller (3) which energizes an amplifier (4) operating a positioning motor (5) which, in turn, changes the position of a fuel control element (7, 207), the instantaneous position of which is fed back to the controller by a position control transducer (6), a signal processing and logic circuit (9, 13) is provided which has the actual fuel supply signal applied thereto. The actual fuel supply signal is evaluated with respect to predetermined limits, for example at a "rest" or OFF position of the fuel control element. This condition can be sensed, for example, based on operating data of the engine, e.g. when a brake light switch is operated, the engine operates above a certain speed, or the vehicle operates at a certain speed, or the like. Additionally, a position sensing switch (8) coupled to the control pedal (1) can be monitored by determining if the output signal from the command transducer is within a limited range when the switch is in a position indicating that the pedal is at, or close to, OFF or "rest" position. By evaluating the actual signal from the respective transducers at predetermined positions of the elements to which they are coupled, e.g. the fuel control element (7, 207) being against an idle or rest stop (16, 216) or the fuel control pedal (1) being at "rest" position, limit switches, particularly in the engine compartment, can be eliminated.

摘要： To decode signals picked up in a horizontal and vertical coil on the vehicle induced by a buried a-c energized cable, in which the vertical position of the coil above the cable is determined, a null sensing circuit is coupled to the horizontal coil to sense when the signal induced therein passes through zero. The signal induced in the vertical coil is likewise sensed, but rather than sensing the null, the peak value is determined. This peak value induced in the vertical coil will occur some time after the signal in the horizontal coil has passed through null or zero, and the peak value in the vertical coil is compared with the rise in signal in the horizontal coil. When the two signals (peak and rising horizontal coil signals) are equal, the time between the equality and the null point of the horizontal signal is determined, and used as a control parameter to steer the vehicle so that this time will be effectively null or zero, at which time the vehicle will be centered over the guide cable. The time can be determined by the count of a counter, the count state of which is transferred to a memory for read-out at a clock rate determined by a steering computer.

摘要： The invention relates to a method and device for diagnosing deviations in a single cylinder lambda control in an internal combustion engine having at least two cylinders and an exhaust gas sensor designed as a broadband lambda sensor, wherein a pump current is evaluated by means of a pump cell and the pump current is used at least temporarily for an individual cylinder lambda control. According to the invention, a pump voltage or a pump voltage change is determined via the pump cell in addition to the pump current and the value is transmitted to a diagnosis apparatus. Deviations in the single cylinder lambda control can thus be better diagnosed without additional material expense according to the invention, which provides advantages in particular in respect of tightened rulemaking in on-board diagnosis. A preferred application of the method is the use in internal combustion engines having multi-bank exhaust systems.

摘要： The invention concerns a procedure to determine the oxygen storage capability of an emission control system with an exhaust gas sensor with discrete-level ability disposed in front of the emission control system.If in a period of time before the determination of the oxygen storage capability, the control intervention of the exhaust gas sensor is ascertained, and if this mean value is taken into consideration when calculating the fuel-delivery control phase during the determination of the oxygen storage capability of the emission control system, or if this mean value is used to correct the lambda value used to calculate the amount of oxygen stored, an improved measuring accuracy can be achieved while using a cost effective discrete level sensor. In that during the rich or lean operation of the cycle to determine the oxygen storage capability, the mean value of the control intervention is used for the calculation, pre-control errors are compensated for, as they can arise, for example, through dispersion of the injection valves or errors in the acquisition of cylinder fill. If the mean value is used to correct the lambda value, the amount of oxygen stored can be more accurately determined as a result of the measured air mass. In the procedure according to the invention, a cost effective step discrete-level sensor can be used in front of the emission control system.

The method allows a reliable diagnosis of the dynamic response of the exhaust gas analyzer probe with excellent differentiation with respect to stochastically occurring fault signals.
