摘要： According to the present invention, the driver's operation quantity and the vehicle running status are measured, the target value of speed ratio or the target value of revolution speed on the input side of the transmission is determined on the basis of the above measured values, and the speed ratio is changed using different algorithms (particularly fuzzy rules) on the basis of the magnitude of deviation between the target value and the actual value.Furthermore, when a vehicle has a continuously variable transmission, a change of at least one of the vehicle acceleration and the shaft torque of a drive wheel is predicted, the engine output torque is controlled on the basis of the prediction, and finite speed ratio characteristics or intermediate characteristics between finite speed ratio characteristics and continuously variable speed ratio characteristics are controlled for the continuously variable transmission. By doing this, speed ratio control stressed on stability is available when the absolute value of the above deviation is small, while speed ratio control stressed on rapid response and smooth acceleration variation is available when the absolute value of the deviation is large.Furthermore, a smooth acceleration feeling and a rapid acceleration response can be realized, the maneuverability is improved, and the driver can find pleasure in more speed ratio characteristics.

摘要： Shift control system and method are provided for use in a vehicle automatic transmission in which a desired speed range is achieved in accordance with the state of driving of a vehicle. The degree of meandering of a running road on which the vehicle is running is detected. The downhill grade of the running road is also detected. Based on the detection results, it is determined whether or not the running road is a meandering downhill road. When it is determined that the vehicle is running on the meandering downhill road, it is then determined whether or not a downshift is needed. When the downshift has been determined to be necessary, the speed range of the vehicle automatic transmission is shifted from a current speed range to a speed range lower than the current speed range.

摘要： This invention relates to a shift control system and method for a vehicle automatic transmission, in which control of a downshift on a downhill road is performed by fuzzy inference. When a vehicle has been determined to be running on a downhill road by a driving state determining device, a speed range setting device sets as an optimal speed range a speed range lower than a current speed range. In the automatic transmission, the state of engagement of a desired engaging element is changed over to achieve the optimal speed range. When the vehicle has been determined to be running on the downhill road by the driving state determining device so that the speed range lower than the current speed range has been set as the optimal speed range and also when no change has been determined in engine load by an engine load detecting device, an engagement state control device reduces engaging force to be produced upon changing over the state of engagement of a desired engaging element for achieving the optimal speed range. This makes it possible to eliminate a sense of incogruity, which would otherwise occur upon shifting to a higher speed range, while assuring a good shifting response.

摘要： In a speed change control method for an automatic transmission for vehicles with a plurality of gearshift positions, the frictional resistance of a road surface is detected, gearshifting to at least a lowest-speed gearshift position is prohibited if the frictional resistance of the road surface is judged to be low. Preferably, gearshifting to at least the lowest-speed gearshift position is prohibited when starting the vehicle from a stopped position if the frictional resistance of the road surface is judged to be low. The frictional resistance of the road surface is determined to be low when an occurrence frequency (%) of the detected frictional resistance value, being less than or equal to a first predetermined value, is more than or equal to a second predetermined value.

摘要： In a continuously variable transmission which is provided with a primary pulley and a secondary pulley, between which a driving belt is mounted, primary and secondary control systems, which are coupled to the respective pressure chambers of the axially translatable pulley discs, are employed to precipitate current pressure values, in dependence upon desired pressure values. To this end, the control system employs a regulator to which only the difference between the desired and the measured pressure-value is supplied, whereby the regulator nevertheless only has to regulate the relatively rapidly changing variation in a rest value supplied separately by a rest state device. This greatly improves the dynamic behaviour of the controller, so that rapid variations in the desired value of the entrant pressure can be effectively followed by the control system.

摘要： In a speed change control method for setting the gearshift position of an automatic transmission for vehicles with a plurality of gearshift positions, to a position selected on the basis of vehicle speed and engine load, in accordance with a preset shift pattern for a first control mode, one of the gearshift positions is selected by fuzzy inference in accordance with at least one of parameter values which represent operating conditions of the vehicle, parameter values which represent driver's driving intention, and parameter values which represent road conditions. Further, the gearshift position of the automatic transmission is set to the position selected by the fuzzy inference only if the gearshift position selected by the fuzzy inference provides a lower speed than that provided by the gearshift position selected in accordance with the shift pattern for the first control mode. Preferably, a plurality of control modes including the first control mode are provided, one of the control modes is selected by the fuzzy inference in accordance with at least the degree of winding and gradient of a road on which the vehicle is traveling, and a gearshift position to be set is selected in accordance with the selected control mode.

摘要： A system for controlling multi-step geared continuously variable automatic transmission in which a gear ratio to be shifted to is determined by retrieving a conventional preestablished shift diagram by an engine load and a vehicle speed. A fuzzy reasoning is carried out using parameters such as a driving resistance to correct the gear ratio obtained by retrieved. Alternatively, the fuzzy reasoning is carried out to correct one of the engine load and vehicle speed detected and using the corrected value, the shift diagram is retrieved to determine a gear ratio to be shifted to. Further, another fuzzy reasoning is carried out to ascertain the driver's intention to decelerate and the first fuzzy reasoning is carried out using the inferred value so as to reflect the driver's intention in the shift control.

摘要： A system for controlling a lock-up clutch of a torque converter in which a target speed ratio of the torque converter of an automatic transmission of a vehicle which mechanically couples a pump impeller connected to an engine output shaft with a turbine runner connected to a transmission input shaft, is determined by carrying out a fuzzy reasoning based on fuzzy production rules using a degree of throttle opening, a grade resistance and a current speed ratio as parameters. Then a second fuzzy reasoning is carried out based on second fuzzy production rules using a deviation between the target speed ratio and the current speed ratio and the change of the deviation as parameters to determine a control value such that the lock-up clutch is controlled between a position at which the clutch is fully engaged and a position at which the clutch is fully not engaged including an intermediate position at which the clutch is partially engaged. With this system, the lock-up control can cope with various vehicle operating conditions so that the vehicle drivability and fuel consumption is improved while suppressing engine noise. This system further enables control that is better matched to the intention, decision-making, and feelings of a human driver.
