摘要： PURPOSE:To provide versatility for the system by installing a memory into which a plurality of different constant pairs are memorized and permitting arbitrary contstant pairs to be selected from outside, in a conroller for controlling the ignition timing according to the knocking state. CONSTITUTION:A mask ROM18 in which a plurality of different constant pairs are memorized is installed into a microcomputer 10 for calculating the ignition timing according to the knocking state detected by a knock sensor 26. The constant for determining the gain of the knocking signal supplied from the knock sensor, constant for determining the gain of the knocking judgement level, off- set value, etc. are memorized as constants. The instruction voltage supplied from outside is set to an arbitrary value by a division resistor 24, and converted to selection code in an A/D converter 20, and one of the constants in pairs is selected by the signal supplied from a decoder 22. Therefore, when similar engines are mounted onto plural kinds of cars, the mask pattern can be used in common.
摘要翻译：目的：通过安装存储器来提供多功能性，其中存储有多个不同的常数对，并且允许从外部选择任意对抗对，在控制器中根据爆震状态控制点火正时。构成：其中存储有多个不同常数对的掩模ROM18安装到微计算机10中，用于根据由爆震传感器26检测到的爆震状态计算点火正时。用于确定从爆震传感器26提供的爆震信号的增益的常数爆震传感器，用于确定爆震判断电平，偏移值等的增益的常数被存储为常数。从外部提供的指令电压通过除法电阻器24设定为任意值，并转换成A / D转换器20中的选择代码，并且由解码器22提供的信号选择成对中的一个常数。因此当将类似的发动机安装在多种车辆上时，可以共同使用掩模图案。

摘要： PURPOSE:To suitably perform speed change control and reverse impeding control by selecting a forward position operational signal, when forward/reverse position operational signals are simultaneously generated, in a condition that a wrong output of the forward position operational signal is not detected, and actuating a reverse impeding device based on a selected reverse position operational signal in a condition that the wrong output is detected. CONSTITUTION:In a signal selecting means, in a condition that a forward position operational signal is not detected wrong output from a forward position operational signal wrong output detecting means, when forward and reverse position operation signals are simultaneously generated, the forward position operational signal is selected. On the other hand, in a condition that the forward position operational signal is detected wrong output, when the forward/reverse position operational signals are simultaneously generated, the reverse position operational signal is selected. Speed change ratio is controlled by a speed change control means while actuating a reverse impeding device by a reverse impeding device control means based on the selected signal by a signal selecting means.

摘要： PURPOSE:To ensure a traveling property by judging a rotating speed detecting means abnormal from the difference in rotating speed between front and rear wheels at the time of the differential limitation of a center differential gear and removing the differential limitation at the time of abnormality in a vehicle in which said center differential gear is assembled to a propeller shaft for transmitting power to said front and rear wheels. CONSTITUTION:In a four wheel drive vehicle having a center differential gear 22 in which a differential limiting mechanism 34 is assembled in the joint part between propeller shafts 20, 21 for transmitting power to front and rear wheels, rotating speed detecting means 24, 26, and 28, 30 for detecting the rotating speeds of front and rear wheels respectively are provided. And, in a controller 32 into which the detected outputs are inputted, the sum of the front wheel rotating speed F and rear wheel rotating speed R is operated and compared with a reference value and, when the sum of the rotating speeds is below the reference value while differential limitation being under way, the magnitudes of both rotating speeds F, R are compared. Here, when F>R (F

摘要： PURPOSE:To prevent the erroneous judgement by judging anomaly on the basis of the output of an O2 sensor when the air-fuel ratio feedback control conditions are satisfied and each of the cooling water temperature, intake air quantity, and the rich side limit value of the air-fuel ratio correction value becomes over each prescribed value. CONSTITUTION:Each detection value of an air flow meter 3, crank angle sensors 5 and 6, water temperature sensor 9, and an O2 sensor 13, etc. is input into a control circuit 10. The control circuit 10 checks if the air-fuel ratio closed loop control conditions are established or not except on start, in the fuel quantity increase in warming, output increase, and fuel cut. When the air-fuel ratio closed loop control conditions are established, and each of the cooling water temperature and the intake air quantity is over each prescribed value, it is checked if the rich side limit value of the air-fuel ratio correction value is over a prescribed value or not. When it is confirmed that the rich side limit value is over the prescribed value and the engine is in the stationary operation state, judgement for anomaly is performed by observing the output of the O2 sensor.

摘要： PURPOSE:To make it possible to facilitate escape from a stuck-up condition, by setting, during limited differential operation, a speed stage higher than a first speed stage when a drive range is selected, or a first speed stage when the other drive range is selected. CONSTITUTION:The output shaft of an engine 1 is coupled thereto with an automatic transmission 3 through a torque converter 2. The output shaft 4 of the transmission 3 is coupled to a center differential gear 5. A wet-type multi-disc clutch 17 for limiting the differential operation is disposed between the casing 7 of the center differential gear unit 5 and a front differential gear unit 12 coupled with one side gear 8. Further, the engaging force of the wet-type multi-disc clutch 17 is controlled by a hydraulic clutch control device 18. In this case, when the drive range is selected during limited differential operation, the shift stage is set to a speed stage higher than a first stage. When the other drive range is selected, the first speed stage is set.
