摘要： A method and system is disclosed by which identification codes for a plurality of systems are utilized to provide a control with an indication of a particular characteristic of the particular system. The characteristic is assigned with an identifying variable, in a disclosed embodiment voltage, which increases. As this variable increases, possible errors due to system features will also increase. Thus, the possibility of the control misreading an identification code due to the error increases. To address this increasing possibility, the distance between adjacent variables also increases as the variables themselves increase. In a preferred embodiment the distance is increased proportionally.

摘要： An electronic engine power control system is disclosed for a motor vehicle wherein a measuring arrangement is utilized for determining the position of an actuating element. The measuring arrangement is configured in such a manner that it has different resolutions in various ranges of the position of the actuating element. The open-loop or closed-loop control of the position of the engine power-determining element or of the actuating element in idle or near idle is undertaken in dependence upon the measurement signal of high resolution while, outside of the idle or near idle range, the control of the actuating element is undertaken in dependence upon measurement signals of low resolution or a straight open-loop control of the position of the actuating element.

摘要： A control device for an internal combustion engine, comprising a calculating unit for calculating an engine control value for controlling an engine running condition on the basis of a conversion value into which a first engine condition value, which represents an engine running condition, is converted, and a converting unit for converting the first engine condition value into the conversion value. The engine control value discontinuously changes at a discontinuous point in accordance with a change of the first engine condition value, and the first engine condition value corresponding to the discontinuous point changes in accordance with a change of a second engine condition value. The conversion value corresponding to the discontinuous point remains constant even when the second engine condition value changes.

摘要： A method for sensing an air-fuel ratio of exhaust gasses from an engine of a vehicle using a sensor is provided. The method may comprise pumping a current in a pumping cell during; reducing said pumping during a set of operating conditions; and adjusting a fuel injection amount or an air amount into the engine to maintain a desired air-fuel ratio based on the sensor. In this way, a reference voltage can be driven by chemical reactions to equilibrate and provide an accurate indication of stoichiometry, similar to a HEGO sensor. Likewise, outside of stoichiometry, the reference voltage is controlled in a one-sided fashion via positive and negative pumping current at respective voltage limits to provide an indication of air-fuel ratio over a wide range.

摘要： A learning and control apparatus for an electronically controlled internal combustion engine having such an object to be controlled as a fuel injection valve for controlling the air-fuel ratio in an air-fuel mixture or an idle speed control valve for controlling the idle rotation number of the engine wherein a pulse duty signal corresponding to a basic control value is set according to engine driving states. The basic control value is corrected by adding an appropriate correction value to the basic control value. Feedback control is carried out so that the actual controlled value is made to follow the aimed control value, and a learning correction quantity is computed by learning said feedback control so that the feedback control amount is set as small as possible. Driving region judging means judges the driving region stored learning correction quantity in a memory map corresponding to the detected actual driving state with such a hysteresis that at least one of the driving region-defining lattice axes in the memory map is shifted by a predetermined value according to the direction of change of the parameter of the engine driving state, thereby when the engine is driven in the driving state near the boundary that is lattice axes, between adjacent driving regions having a large difference between respective learning correction quantities no hunting phenomenon of the control quantity in engine driving and stable control characteristics can be maintained.

摘要： An ECU converts a cylinder pressure P and a cylinder volume V corresponding to a crank angle θ at least from a compression stroke to a combustion and expansion stroke to a logarithmic value log P and a logarithmic value log V, respectively, to find a logarithmic conversion waveform and estimates a motoring waveform which is obtained by subtracting a pressure rise developed by combustion in a cylinder from the logarithmic conversion waveform, that is, corresponds to a non-combustion state. Further, the ECU computes a determination line Y of an ignition timing Tburn on the basis of the base line X of the estimated motoring waveform and determines the ignition timing Tburn on the basis of this determination line Y and the logarithmic conversion waveform.
