| 20100004091 | LOCKUP CLUTCH CONTROL DEVICE FOR VEHICLE - In a vehicle mounting an engine equipped with an exhaust turbocharger and a fluid transmission device as the power transmission device, occurrence of surging in the exhaust turbocharger is prevented at the time of connecting a lockup clutch in the fluid transmission device. When a condition for connecting the lockup clutch is held to lock up the fluid transmission device coupled to the engine | 01-07-2010 |
| 20110294621 | METHOD FOR CONTROLLING THE POWER TRANSMISSION IN A DRIVE TRAIN AND DRIVE TRAIN - The invention relates to a method for controlling the power transmission in a drive train, in particular of a motor vehicle, wherein the drive train comprises: an internal combustion engine which drives an output shaft at an engine speed and generates an exhaust gas stream; an exhaust gas turbine which is arranged in the exhaust gas stream and is engaged in or can be switched to a drive connection with the output shaft in order to transmit the drive power of the exhaust gas turbine to the output shaft; a compressor which is arranged in a fresh air stream supplied to the internal combustion engine and which is engaged in and driven by a drive connection with the exhaust gas turbine in order to charge the internal combustion engine at a predefined charging pressure; a power-controlled hydrodynamic clutch, which is arranged in the drive connection between the exhaust gas turbine and the output shaft and by means of which drive power of the exhaust gas turbine is transmitted to the output shaft depending on the power controller, and which has a primary wheel that is driven by the exhaust gas turbine and a secondary wheel that is driven hydrodynamically by the primary wheel and in turn drives the output shaft. The method according to the invention for controlling the power transmission in a drive train, in particular of a motor vehicle, controls the power transmission of the hydrodynamic clutch depending on certain input variables. | 12-01-2011 |
| 20120035017 | POWER CONTROL DEVICE - A power control device includes: an engine control unit and a transmission control unit provided so as to control power of the engine, and configured such that if an actual operating point, which is an operating point indicating a combination of actual revolution speed and torque of the engine, is located in a non-supercharging region and a final target operating point, which serves as a target operating point during acceleration, is located in a supercharging region, the revolution speed of the engine is increased until the actual operating point is shifted into the supercharging region, and the revolution speed of the engine is decreased after the actual operating point has entered the supercharging region, thereby shifting the actual operating point into the final target operating point when accelerating the vehicle. | 02-09-2012 |
