摘要： A transmission includes a stationary member, an input member, and gear sets each having a plurality of nodes. The transmission includes a first clutch that connects a node of one gear set to the stationary member to establish an L1 mode, and a second clutch that connects a node of another gear set to the stationary member to establish a 2L mode. A SOWC is connected between nodes of two gear sets, and a controller, in response to a requested shift L1-L2 shift while engine braking, executes a method to release the first clutch and thereby enters a neutral mode. The SOWC is released when slip across the first clutch exceeds a first threshold, then the first clutch reapplied when a SOWC slip level exceeds another threshold to thereby enter a 1st gear freewheeling mode. The second clutch is reapplied to enter the L2 mode and resume engine braking.

摘要： A system for reducing the likelihood of brakes of a vehicle overheating when towing a trailer includes a transmission configured to operate in a plurality of gear ratios and a GPS unit configured to detect location data. The system also includes an input device configured to receive data indicating whether the trailer is connected to the vehicle and an ECU coupled to the transmission, the GPS unit and the input device. The ECU is designed to determine whether the vehicle is within a predetermined distance of a downgrade of a road based on the location data, determine a current gear ratio of the transmission and determine whether it is desirable for the transmission to operate in a second gear ratio that is lower than the current gear ratio based on whether the trailer is connected, whether the vehicle is within the predetermined distance, and the current gear ratio.

摘要： A vehicle and methods of braking the vehicle on a downhill grade as automatically implemented by a computing device are disclosed. One method includes detecting application of a vehicle brake and detecting acceleration of the vehicle while the vehicle traverses the downhill grade. Based on detection of the application of the vehicle brake and detection of the acceleration of the vehicle, the method also includes sending a command to downshift a transmission of the vehicle. If, after the downshift of the transmission, the application of the vehicle brake is not detected for a threshold time, the acceleration of the vehicle falls below a threshold acceleration, or the downhill grade falls below a threshold grade, the method can further include sending a command to upshift the transmission.

摘要： A method of shift control for an automatic transmission of vehicle power train, having a permanent brake between a drive motor and a final drive, in which current vehicle-specific, road-specific and driver-specific operating parameters, topographical data relating to an upcoming stretch of road ahead of the vehicle are determined while driving, and from which a tractive resistance value for the upcoming stretch of road is determined, and control commands for thrust downshifts and/or upshifts are derived and implemented, within the transmission, during a thrust operation depending upon the tractive resistance value. This is achieved in that the maximum permanent braking force curves that are possible for the upcoming stretch of road, in the currently engaged gear, and each adjacent gear is determined based on the current traveling and engine speeds and analyzed to derive control commands for a thrust downshift and/or upshift in relation to the tractive resistance value.

摘要： A manner of managing operation of a machine is described for preventing damage/wear to movable machine components arising from operation of the machine/parts at excessive speed while the machine is traveling down a steep incline. The managing of the machine operation includes determining a downhill slope value in a machine direction of travel and then establishing a maximum commanded transmission output speed in accordance with the determined downhill slope value. Thereafter a maximum commanded gear ratio is established, for a transmission having a variable gear ratio, based upon the maximum commanded transmission output speed and a current engine speed. A controller compares the maximum commanded variable gear ratio to an operator requested gear ratio, and a target gear ratio is established for the variable gear ratio of the transmission based upon a minimum of the compared commanded variable gear ratio and the operator requested gear ratio.

摘要： A hydraulic pressure of each corresponding one of a plurality of friction elements of a gear shift mechanism of the automatic transmission is controlled to downshift the gear shift mechanism from a current gear stage to a next gear stage, at which an engine brake is operated, upon receiving a driver's demand for deceleration. An engine output of the engine is increased by increasing a throttle opening degree of the engine in at least two steps in an absence of a driver's operation on an accelerator of the vehicle at the time of the downshifting of the gear shift mechanism from the current gear stage to the next gear stage.
