摘要： A drive train including an internal combustion engine with a crankshaft, and having a spur gear arrangement with at least one transmission input shaft that is coupled to the crankshaft by a friction clutch. A clutch plate within a housing of the friction clutch is connected in a rotationally locked manner to the at least one transmission input shaft and includes a centrifugal force pendulum. To accommodate the centrifugal force pendulum in the drive train in a space saving manner, the centrifugal force pendulum is situated on the at least one transmission input shaft at an axial distance from the clutch plate.

摘要： In a control device for a vehicle including: a dog clutch mechanism that is disposed in a power transmission path in which a driving force is transmitted from an engine to a wheel and is operated by a hydraulic actuator; and an electric oil pump that supplies hydraulic pressure to the hydraulic actuator, rotation of the engine is stopped in a state in which the dog clutch mechanism is engaged by the hydraulic pressure supplied from the electric oil pump at a time during an engine stop operation, the rotation of the engine is started in the state in which the dog clutch mechanism is engaged by the hydraulic pressure supplied from the electric oil pump at a time during an engine restart operation, hence occurrence of up-lock of the dog clutch mechanism is prevented.

摘要： A system is provided for managing torque in a vehicle driveline coupled to an internal combustion engine and to a hybrid motor/generator. An engine control circuit provides to a transmission control circuit an engine torque value corresponding to torque applied by the engine to the driveline. A hybrid control circuit provides to the transmission control circuit a motor torque value corresponding to torque applied by the hybrid motor/generator to the driveline. The transmission control circuit controls operation of at least one friction device and controls shifting of the transmission, and also manages torque applied to the drive line by the engine and by the hybrid motor/generator based on the engine torque value and the motor torque value such that the friction device control and shift schedule instructions do not require modification to accommodate inclusion of the hybrid motor/generator in the system or exclusion of the hybrid motor/generator from the system.

摘要： A method of controlling shifts in a multi-speed transmission includes beginning an initial shift, which changes the transmission from a starting gear to an initial target gear, and executing an adjusted shift, which changes the transmission to an adjusted target gear having higher speed ratio than the initial target gear, when transition conditions are satisfied. The transition conditions include a threshold increase in torque request, which is sufficient to require the transmission to be placed into the adjusted target gear. The transition conditions also include a common controlling clutch, which is partially engaged during the initial shift and the adjusted shift and is an off-going clutch to place the transmission in the adjusted target gear. Executing the adjusted shift does not include placing the transmission in a neutral mode. Furthermore, executing the adjusted shift does not include completing the initial shift.

摘要： A method of controlling an automated transmission for motor vehicles with one or several pressure activated positioning cylinders (6, 8, 20), via the assigned shift valves (10, 12), at least one main cut-off valve (4) which is positioned prior to the shift valves, and a control device for controlling the shift and main cut-off valves. The pressure requests, for the shifting, are determined and the respective main cut-off valves are triggered depending on the determined pressure requests. To enable a variable match of the supply pressure during transmission shifts, respective optimized pressures or pressure patterns are determined for certain shift scenarios which, for instance, consider a mass to be synchronized, the existence of a tooth-on-tooth position, or the like. Through this method, for instance, the load on shift elements, the shift timing, and the shift noise can be positively influenced.

摘要： A vehicle powertrain includes a transmission and a clutch. The slip of the clutch is adjusted to a target where a magnitude of a sensed parameter of a shaft of the transmission corresponds to a desired noise, vibration, and harshness (NVH) level in the powertrain. The sensed parameter of the transmission shaft may be one of acceleration, speed, and torque of the transmission shaft. The transmission shaft may be one of the input shaft and output shaft of the transmission.

摘要： A method of managing clutch thermal loads in a multi-speed dual-clutch transmission (DCT) that is paired with an engine in a vehicle. The method includes assessing whether the vehicle is being accelerated and identifying a DCT clutch slipping during the acceleration. The method also includes determining vehicle parameters, determining an amount of time remaining for the clutch to stop slipping using the determined vehicle parameters, and determining an amount of time remaining until the clutch reaches a threshold temperature. The method additionally includes comparing the determined amount of time remaining for the clutch to stop slipping with the determined amount of time remaining until the clutch reaches the threshold temperature. Furthermore, the method includes activating an indicator if the determined amount of time remaining until the clutch reaches the threshold temperature is less than the determined amount of time remaining for the clutch to stop slipping.

摘要： A motorized vehicle includes a transmission system and an inch/brake device providing at least two ranges of motion. An engagement force of the transmission system is provided in a first range of motion of the inch/brake device, and a braking force of the motorized vehicle is provided in a second range of motion of the inch/brake device. An accelerator device moves between two or more positions, wherein moving the accelerator device from one position to another position causes an amount of overlap between the first and second ranges of motion of the inch/brake device to vary.

摘要： When a capacity coefficient (Cre) of a torque converter is larger than or equal to a predetermined threshold (CreA), a speed ratio (e) is calculated on the basis of an actual power transmission efficiency (η) by referring to a predetermined unique relationship between a power transmission efficiency (η) and a speed ratio (e). Therefore, even in a second speed ratio variation range (R2) in which the capacity coefficient (Cre) is larger than or equal to the threshold (CreA) and the speed ratio (e) is not uniquely determined for the capacity coefficient (Cre), the speed ratio (e) is calculated using the unique relationship between the speed ratio (e) and the power transmission efficiency (η), so the speed ratio (e) may be calculated in all the speed ratio variation range of the torque converter.
