摘要： A method of controlling an automated manual transmission system having a transmission and a shifter is provided. The shifter includes a Drive Mode, a Low Mode and at least one of a Manual Mode and a Hold Mold. The Drive Mode automatically selects a default gear of the transmission and automatically performs all upshifts and downshifts. The Manual Mode permits an operator to manually select an upshift and a downshift of the transmission. The Hold Mode permits an operator to maintain a current operating gear. Control determines whether the shifter is in one of the Manual Mode and the Hold Mode. Control determines whether a vehicle operating condition is outside of a predetermined threshold. Control operates the transmission in Drive Mode based on the vehicle operating condition being outside of the predetermined threshold irrespective of the shifter being in one of the Low Mode, Manual Mode or Hold Modes.

摘要： A hybrid vehicle includes powertrain components such as an engine, an automatic transmission, and a traction motor selectively coupled to the engine via a clutch and to the transmission. At least one controller is programmed to control these powertrain components. The vehicle is driven over a drive cycle that includes multiple engine starts and transmission gear shifts. An amount of fuel consumption used during these engine starts and transmissions gear shifts is stored on an on-board storage device. Subsequently, the engine is inhibited from starting and the transmission is inhibited from shifting gears based on the amount of fuel consumption associated with the engine starts and transmission gear shifts performed during the drive cycle as recalled from the storage device.

摘要： A vehicle includes a transmission and a controller. The controller is configured to receive a torque request, calculate an SFC for satisfying the torque request in an initial gear and in an alternate gear, and command the transmission to shift from the initial gear into the alternate gear in response to the calculated SFC for satisfying the torque request in the alternate gear being less than the calculated SFC for satisfying the torque request in the initial gear.

摘要： A control system and method for adaptively controlling transmission ratio shifting in an electronically controlled transmission. A refueling event is detected. After the detected refueling event, fuel consumption is monitored for a predetermined period during which a change in composition of fuel to the engine reaches or approaches a steady state. During the period, the rate of adapting transmission shift controls is modified to respond quicker to the change in shift characteristics induced by differences in torque produced by the engine. Implementing this method can improve transmission shift quality while the quality of fuel reaching an engine is in transition.

摘要： A change gear control device is provided for an automatic transmission in a motor vehicle propelled by an internal combustion engine which is operated with an air/fuel mixture having air/fuel ratios ranging from a fuel rich air/fuel ratio to a fuel lean air/fuel ratio depending on driving conditions of the motor vehicle. In this device a first detector detects an engine torque of the internal combustion engine and a second detector detects a vehicle speed of the motor vehicle. A processor processes transmission gear ratios for the automatic transmission. In particular, the processor reads the detected engine torque from the first detector and the detected vehicle speed from the second detector, determines a new transmission gear ratio based upon the engine torque and the vehicle speed, and outputs a signal representing the new transmission gear ratio to the automatic transmission, whereby a gear shifting operation is effected at a timing based on an engine torque variation due to an operating air/fuel ratio change.

摘要： The present invention relates to a method and an apparatus for controlling a car equipped with an automatic transmission having a lockup clutch. According to the control method of the present invention, when the lockup clutch is in the lockup state, a variation of a generated torque is detected. When the range of the torque variation detected exceeds a predetermined value, an engine torque is reduced by controlling the engine, and the automatic transmission is controlled to compensate for a reduction of the driving torque due to a reduction of the engine torque. Thus, the speed change ratio is changed to the low gear side. The control unit of the present invention includes a unit for controlling an output torque of an engine according to a command value, a unit for hanging the transmission ratio of the automatic transmission, a unit for detecting a variation of the engine torque, a unit for deciding a target driving torque, a unit for reducing a torque command value when the range of a detected variation of the torque has exceeded a predetermined value when the lockup clutch was in the lockup state, and a unit for deciding a transmission ratio at which the reduction of the driving torque due to the reduction of the engine torque is compensated for.
