摘要： A method of indicating when a shift operation of a manual gearbox is to be preformed includes a step for comparing a detected vehicle speed with a reference vehicle speed which is determined and changed on the basis of a detected engine operational parameter and a step for indicating that the shift operation should be performed on the basis of a result of the comparison. The reference vehicle speed is corrected to a lower speed in response to an increase of a total running time of the vehicle, thereby to maintain the driveability of the vehicle when the running time of the vehicle is short.

摘要： An oxygen concentration sensing apparatus includes an oxygen pump element and a sensor cell element with a pair of electrodes respectively, being disposed to face each other, to form a restricted region between them, and a current source for supplying a pump current across the electrodes the oxygen pump element. A limit voltage is adjustably set in response to a voltage across the electrodes of the oxygen pump element, and the pump current supplied to the oxygen pump element is reduced when a voltage generated across the electrodes of the sensor cell element has exceeded the limit voltage.

摘要： An apparatus for sensing the concentration of oxygen in a gas such as engine exhaust gas includes an oxygen concentration sensor formed of an oxygen pump element and a sensor cell element, each based on a solid electrolytic member formed of a material such as ZrO.sub.2, and is provided with a limiter circuit which functions to reduce the level of current supplied to the oxygen pump element when a voltage produced by the sensor cell element indicates that this current level is such as to produce a "blackening" phenomenon whereby deterioration of the oxygen pump element will occur and oxygen concentration sensing reliability will be lowered. The apparatus also includes a delay circuit which functions such that a reduction of the oxygen pump element current level is delayed by a predetermined time interval, after an increase of the sensor cell element voltage to the "blanking" region is detected, thereby preventing fluctuations in the oxygen pump element current level due to transient increases in sensor cell element voltage and increasing the sensing reliability.

摘要： Method and system for detecting a level of an engine oil of an engine include an operation for detecting a time duration in which the engine is operating. When the engine operation has continued for more than a predetermined time period, and the engine is stopped subsequently, the oil level is detected after the elapse of a second predetermined time period in which the engine is stopped. By this feature, the engine oil level is detected very accurately.
