摘要： It is disclosed a system and method for maintaining the operation of an automated transmission (16), particularly a dual clutch transmission, for a motor vehicle, in case of a failure of an engine speed sensor (50) or a bus connection (44) between a first control module (42) controlling an engine (28) being connectable to the transmission (16) through at least one separation clutch (12, 149, and a second control module (34) controlling regulating units (12, 14) for connecting the engine (28) to the transmission (16) or to one or more driving wheels (34) in a force-transmitting manner, wherein gear-shift relevant data, particularly a number of revolutions (ne) of the engine, is exchanged between the control modules (34, 42) over the bus connection (44), the method comprising the following steps: checking whether a number of revolutions (ne; n1, n2) of a shaft (22; 30, 32, particularly an engine shaft (22), which is detected by a sensor (50) of one of the control modules (42) dedicated to this purpose can be transmitted from the one of the control modules (34, 42) via the bus connection (44) to the other one of the control modules (42, 34); and performing the following steps, if the number of revolutions cannot be transmitted: opening all synchronizer devices assigned to the transmission (16) or one of the partial transmissions (18, 20) so that the engine shaft (22) can no longer transmit force via a transmission shaft to the driving wheels (33) of the motor vehicle; closing the separations clutch (12, 14) assigned to the transmission (16) or the partial transmission (18, 20) by means of the opened synchronizer devices, if this separation clutch (12, 14) is not closed; detecting a number of revolutions (n1, n2; ne) of another shaft (24, 26), particularly the transmission shaft, which can be connected to the shaft (22) through the separation clutch (12, 14) by means of a sensor (36, 38) of another control module (34), wherein the sensor (36, 38) is dedicated to this purpose; and determining a gear-shift ramp function for one of the control modules (34, 42), preferably the second control module (42), based on the detected number of revolutions, particularly from a field of characteristic lines, for allowing performance of a shifting process from a source gear to a target gear (FIG. 4).

摘要： A system and method for maintaining the operation of an automated transmission (16), particularly a dual dutch transmission, for a motor vehicle, in case of a failure of an engine speed sensor (50) or a bus connection (44) between a first control module (42) controlling an engine (28) being connectable to the transmission (16) through at least one separation clutch (12, 149), and a second control module (34) controlling regulating units (12, 14) for connecting the engine (28) to the transmission (16) or to one or more driving wheels (34) in a force-transmitting manner, wherein gear-shift relevant data, particularly a number of revolutions (no) of the engine, is exchanged between the control modules (34, 42) over the bus connection (44).

摘要： A method for controlling an automatic transmission in a vehicle is provided. The method selectively provides automatic engine braking for the vehicle. When it is determined that automatic engine braking is desired, the upshift schedule is increased, such that a higher vehicle speed is required to upshift for any given accelerator pedal position. The transmission is automatically downshifted to a lower gear to provide engine braking for the vehicle, when a vehicle acceleration threshold is exceeded. The automatic downshifting of the transmission can occur when the brake pedal is engaged, and when the brake pedal is disengaged.
