摘要： When slipping is generated during the upshifting from a first gear shift stage to a second gear shift stage on ice or the like, a control for prohibiting the upshifting from the second gear shift stage to a third gear shift stage can be carried out precisely. A control system is designed so that when a slipping state is detected on ice having a lower road surface friction coefficient by a slipping state determining device, the upshifting of an automatic transmission from a second gear shift stage to a third gear shift stage is prohibited. In this control system, the time required for the upshifting from a first gear shift stage to the second gear shift stage is measured. If such time is shorter than a first predetermined time, it is determined that a slipping has been generated during the upshifting, and the upshifting from the second gear shift stage to the third gear shift stage is prohibited for a second predetermined time. Thus, even when the determination of the slipping state by the slipping-state determining device is not in time, the further upshifting of the automatic transmission is prohibited. Therefore, it is possible to reliably avoid the carrying-out of undesirable upshifting.

摘要： A control system, which creates a neutral condition if a vehicle is stationary with the brake of the vehicle being actuated and the accelerator for the engine being turned off while the transmission is set in a drive range, is equipped with a brake switch (36), which detects the operational condition of the brake, and a output rotation sensor (40), which detects the rotational speed of the output member of the transmission. If the control system detects the rotation of the output member by the output rotation sensor (40), then the control system terminates the neutral condition in spite of the operational condition of the brake, which is detected by the brake switch (36).

摘要： A system for controlling an automatic transmission of a vehicle, wherein the initial value of the desired pressure to be supplied to a hydraulic clutch for the current gear now being engaged is determined appropriately, when conducting a power-on downshifting, so as to decrease the shift shock experienced by the vehicle occupant effectively, irrespectively of the change in the throttle opening, while ensuring to reduce the volume of the mapped data.
