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 at starting the vehicle 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 the sum of detection frequency(%) of the detected frictional resistance values, each of which is a first predetermined value or less, is a second predetermined value or more.

摘要： When a vehicle is traveling on a descending slope, the gearshift position of an automatic transmission is set to a position selected in accordance with driver's intention of accelerating the vehicle based on accelerator opening. A decision is preferably made as to whether the gearshift position should be set to a low-speed gearshift position where an engine brake can be applied, in accordance with the magnitude comparison between a threshold value and at least one value of gradient of a road and time-dependent change in vehicle speed. The threshold value may be changed to a value that causes the low-speed gearshift position to be easily selected if the frictional resistance of the road surface is judged to be low. Further, the threshold value may be set beforehand which corresponds to the degree of gradient and/or winding of the road, and the threshold value is changed to a value that causes the low-speed gearshift position to be easily selected if the detected operating amount of braking exceeds a predetermined standard value.

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, and 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： The determining method includes a step of continuously measuring the relative movement between the wheel (W F ) and the vehicle body (12) by use of a linear stroke sensor (28) while a motor vehicle is running; a step of creating spectral distribution by subjecting the output of the linear stroke sensor (28) to FFT frequency analysis; a step of calculating characteristic values (F) inherent to various types of road surfaces; and a step of specifying the type of the road surface based on the calculated characteristic values (F). When the type of the road surface is specified, the damping force of the suspension (10) is changed to a level corresponding to the type of the road surface. This level may be determined by a Fuzzy inference section (44).
