摘要： PURPOSE:To enable specified control to be carried out even if kind of fuel and characteristic of engine output torque are varied by correcting a parameter which represents detected engine load based on concentration detected by a standard fuel concentration detection means so as to control an automatic transmission. CONSTITUTION:A cylinder intake air quantity calculated based on an intake air flow quantity Q detected by an air flow meter 8 and engine speed N detected by a crank angle sensor 9 is set as a parameter TQ which represents engine load by means of a control unit 6. On the other hand, a correction coefficient COMET is set based on alcohol concentration detected by an alcohol concentration sensor 12 and the parameter TQ is multiplied by the correction coefficient COMET and the corrected result is finally set as a parameter TQSEN which represents the engine load. Line pressure in a control valve group 5 is set based on the parameter TQSEN.

摘要： PURPOSE:To enable proper transmission control in accordance with road surface conditions such as a slippery surface, a curved road and a very hilly road by detecting the acceleration of a vehicle including the vehicle direction, and performing speed change control while taking account of information on the vehicle body acceleration detected. CONSTITUTION:A vehicle acceleration arithmetic means A carries out arithmetic of the acceleration of a vehicle according to a vehicle speed detected from a vehicle driving system by a vehicle speed detecting means B. a comparing means D compares the acceleration with the vehicle acceleration in its forward and backward directions detected by a vehicle acceleration detecting means C and, when the former is bigger than the latter, diagnoses that slip occurs, and selects a transmission pattern for controlling the gear to a gear position higher than the normal position by a slip transmission control means E. A holding type transmission control means F sets a transmission point mainly according to the vehicle speed when the vehicle acceleration in the transverse direction or the average value per unit time of the accerelation is big, and selects a holding type transmission pattern by which the gear is fixed in a lower gear position at less than intermediate speed. Thus stable driving performance is obtained.

摘要： PURPOSE:To reduce any shift shock in an automatic transmission, being assembled in an engine in which alcohol mixed fuel is used, so stably irrespective of alcohol content. CONSTITUTION:At the time of gearshifting, engine output torque is lowered to some extent, thereby preventing any shift shock from occurring. Here, alcohol content in fuel to be fed to the engine is detected, and an engine load condition, determining a torque-down control range on the basis of this alcohol content and shift type, is variably set (S1). In addition, a car speed condition, setting the torque-down control range on the basis of the shift type is set (S2). On the basis of the engine load condition and the car speed condition, finally the torque-down control range is set (S3), and when gearshifting is performed in this torque-down control range, the engine output torque is lowered.

摘要： PURPOSE:To prevent occurrence of run-out of fuel in a vehicle using mixed fuel, by comparing a detected value signal outputted from a fuel residual quantity detecting means with a signal of a reference value of the residual quantity of fuel set by a fuel residual quantity reference value setting means. CONSTITUTION:A detected value signal outputted from a fuel residual quantity sensor 1 is inputted to a control unit 2 wherein microcomputer is incorporated. To the unit 2, a detected value signal outputted from an alcohol sensor 3 as a detecting means of concentration of alcohol of mixed fuel wherein alcohol is mixed in gasoline, for instance, is inputted. The unit 2 is equipped with a fuel residual quantity reference value setting means 5 which sets a reference value of the residual quantity of the fuel on the basis of the detection signal from the sensor 3 and with a judging means which compares the detected value signal outputted from the sensor 1 with a signal of the reference value of the residual quantity of the fuel set beforehand and judges whether or not a detected value is below the reference value. When the detected value is judged to be below reference value by the judging means, an alarming means 4 issues an alarm.

摘要： PURPOSE:To set the line pressure properly corresponding to engine output torque so as to reduce the shock in speed change and to facilitate the preparation work of a line pressure map by arranging the constitution such that the line pressure of an automatic gearbox is set based on the area of the opening of an engine intake system and the revolution of the engine. CONSTITUTION:A line pressure controller for automatic transmission is composed of an opening area detecting means, which detects the opening area of an engine intake system for variable control, an engine revolution detecting means, which detects the revolution of an engine, and a line pressure setting means, which sets the line pressure based on the opening area detected and the engine revolution. The detecting means for opening area and revolution of the engine detects the opening area of the engine intake system and the revolution of the engine, and the line pressure setting means sets the line pressure based on both detected values. The setting of the line pressure fit for engine output torque is thereby made possible, and the reduction effect of the shock in speed change improves. Moreover, there is no necessity of doing the matching of line pressure over again even if a speed change map is changed.

摘要： PURPOSE:To secure responsiveness and restrain fluctuation of line pressure due to fluctuation of fuel injection as much as possible by providing a basic line pressure setting means, injection change rate detection means, first correction means, opening change ratio detection means, second correction means and control signal output means. CONSTITUTION:A first correction means (d) corrects a basic line pressure so as to restrain fluctuation of basic line pressure to be set by a basic line pressure setting means (c) according to change ratio of fuel injection detected by an injection change ratio detecting means (a). In the case of large change in fuel injection due to intake pulsations, change in basic line pressure becomes large. The fluctuation of line pressure is, however, restrained effectively by a first correction means through the correction of basic line pressure. Since the opening of throttle valve changes upon acceleration/deceleration, the line pressure can be changed with a good responsiveness through the correction of basic line pressure by a second correction means (e) in response to the throttle valve opening detected by an opening change ratio detection means (b) even if response delay is in setting fuel injection.

摘要： PURPOSE:To carry out appropriate speed change control and lock-up control according to the change in alcohol concentration of a fuel. CONSTITUTION:Alcohol concentration MET is judged in three steps (S1-S5) in an automatic transmission for vehicle combined with an engine using a mixed fuel of alcohol and gasoline. A map correspondent to a judged alcohol concentration level is preliminarily selected in step S6 among speed change pattern maps and lock-up maps proper to each alcohol concentration MET. The selected map is referred based on a throttle valve opening TVO and a car speed VSP, and speed change control (S8) and lock-up control (S9) are carried out.

摘要： PURPOSE:To reduce speed change shock by correcting the change of line pressure set by a line pressure setting means in the delay direction when the rate-of- change of throttle valve opening is over the specified value as well as when the throttle opening before the stepping-in of an accelerator pedal is below the specified value. CONSTITUTION:The rate-of-change of throttle valve opening is detected by an opening rate-of-change detecting means. In case the detected rate-of-change is over the specified value as well as when the throttle valve opening before the stepping-in of an accelerator pedal detected by a throttle valve opening detecting means is below the specified value, the stepping-in is judged to be that from the low opening of a throttle valve, and the change of line pressure set by a line pressure setting means is corrected in the delay direction by a line pressure correcting means. The appropriate line pressure matching engine output torque change delayed in relation to the throttle valve opening change can be thereby obtained to dissolve speed change shock.
