摘要： Disclosed is a method used in an automatic transmission for controlling shifting into neutral when a vehicle is stopped in a first speed. The method comprises the steps of (a) determining if a vehicle speed is less than a predetermined speed; (b) determining if a grade in the road is greater than a predetermined value if step (a) is satisfied; (c) determining if a throttle valve opening is 0% if step (b) is satisfied; (d) determining if a present shift speed is a first speed of a drive D range or a drive D2 range if step (c) is satisfied; (e) determining if an oil temperature is greater than a predetermined temperature if step (d) is satisfied; (f) determining if present engine rpm Ne is within a predetermined range if step (e) is satisfied; (g) determining if output rpm of the transmission is 0 rpm if step (f) is satisfied; (h) determining if turbine rpm of a torque converter is 0 rpm if step (g) is satisfied; (i) determining if a brake has been depressed by the driver if step (h) is satisfied; and (j) performing control into neutral if step (i) is satisfied, then returning to the step (c) of determining if the throttle valve opening is 0%. If the vehicle speed is greater than the predetermined speed in step (a), a present shift state is maintained. If the grade in the road is less than the predetermined value in step (b), it is determined if the grade in the road is less than 0%, and if it is, the present shift state is maintained, and if it is not, the process is returned to step (b). Also, if any one of the conditions of steps (c) through (i) is not satisfied, N-D shifting is performed.

摘要： An automatic transmission controller is capable of compensating for both driver type and tendencies of a driver in temporary acceleration, such as in passing. The automatic transmission controller executes a driver type judging subroutine for judging the overall acceleration habits of the driver and classifying the driver as one of a plurality of driver types by monitoring the driving behavior for a predetermined time. The controller also executes a temporary acceleration inclination judging routine for judging the habits of the driver in temporary acceleration by monitoring driving behavior for a period of time shorter than the predetermined time, and executes shift control routines for controlling and changing the shift timing based on the judged driver type and the inclination in temporary acceleration. The controller controls shift timing, taking into account both the driver type and the inclination in temporary acceleration, such as passing.

摘要： A shift control apparatus for a motor vehicle including an Internal combustion engine and a continuously variable transmission (CVT) is provided for controlling the speed ratio of the CVT depending upon operating conditions of the vehicle. The control apparatus determines whether an electronic throttle valve of the engine is at fault or not, and restricts the speed ratio of the CVT when the throttle valve is at fault such that the input-side rotation speed of the transmission is variable within a range that is narrower than a range in which the rotation speed is variable during normal running of the vehicle. The range of the input-side rotation speed may be defined by the upper limit, or the lower limit, or both the upper limit and the lower limit.

摘要： An automatic transmission system has a switching mechanism for switching a plurality of shift gears and a sub-clutch by which transfer torque is controlled while being transferred from an input shaft to an output shaft. An actual deceleration speed is calculated based on an engine speed. Calculated next, based on an engine torque, is a target deceleration speed at which an output torque generated during upshifting is almost equal to an output torque generated after the upshifting. The transfer torque is controlled by feedback control so that the actual deceleration speed reaches the target deceleration speed.

摘要： A shift control method for an automatic transmission while a vehicle runs up a slope while towing a trailer includes the steps of determining if present shift lever position indicates a driving range 2, calculating weight-slope resistance if the shift lever position indicates the driving range 2, determining if the weight-slope resistance is greater than a threshold weight-slope resistance, measuring time duration during which the weight-slope resistance is maintained over the threshold value if the weight-slope resistance is greater than the threshold weight-slope resistance, determining if the time duration is longer than a threshold time, converting a present normal shift pattern into a trailer-towing shift pattern if the time duration is longer than a threshold time, and returning the trailer-towing shift pattern to the normal shift pattern if the weight-slope resistance becomes equal to or less than the threshold weight-slope resistance and this condition is maintained over a second threshold time.

摘要： A control system for a continuously variable automatic transmission for an automotive vehicle, includes a throttle opening sensor that detects a throttle opening, and a controller that executes a change-speed control in a normal mode in which a desired transmission input speed is determined based on operating conditions of the vehicle and a desired transmission ratio is determined based on the desired transmission input speed when the throttle opening is less than a first value, and that executes the change-speed control in a linear mode in which the desired transmission ratio is fixed to a second value when the throttle opening is greater than or equal to the first value. The second value is set based on the desired transmission ratio used in the normal mode prior to switching to the linear mode.
