Abstract: A lock-up clutch control device is provided for a vehicle having a torque converter with a lock-up clutch disposed between an engine and a continuously variable transmission such that the occurrence of shocks during lock-up engagement is suppressed. The vehicle lock-up clutch control device is provided with a control unit that controls the lock-up capacity based on an engine torque signal when engaging the lock-up clutch. The control unit uses a predictive engine torque as the engine torque signal for use in the lock-up capacity control. The predictive engine torque is calculated based on an engine torque air response delay and a hydraulic response delay in the lock-up differential pressure and is faster in response than the actual engine torque.

The clutch housing is rotationally supported within the transmission housing. The selective engagement of the dual clutch assembly interconnects the dual clutch housing with at least one of a first input member and a second input member. The transmission also includes a plurality of gear sets associated with various forward and reverse gear ratios, a controller implemented with an algorithm that provides a lock-up profile for the dual clutch assembly, and a plurality of synchronizer assemblies that couple at least one of the gear sets with at least one of a first countershaft and a second countershaft. The selective engagement of at least one of the synchronizer assemblies establishes at least one of the forward speed ratios.

Abstract: A method of estimating a torque of a transmission clutch may include adjusting an error, deducing an estimated engine angular speed and deducing an estimated clutch torque. The error may be adjusted by deducing an engine transient torque based on an engine angular speed measured using a sensor, an engine static torque deduced using a data map and a load torque depending on a driving load. The estimated engine angular speed may be deduced based on the engine static torque and the engine transient torque. The estimated clutch torque may be deduced by summing an integration value and an error compensation value. The integration value and the error compensation value may be deduced based on a difference between the estimated engine angular speed and the measured engine angular speed.

Abstract: Actual-rotational-difference absorption-torque calculation means 150 inputs a rate-of-change ΔNe of an engine speed during shifting to an actual rotational difference absorption torque-ΔNe table 160 so that an actual-rotational-difference absorption-torque average value during shifting is calculated. Engine-torque calculation means 180 inputs a throttle opening and an engine speed to engine-torque estimation-value map 190, and derives an engine torque during shifting. An actual clutch capacity is calculated from the sum of the actual-rotational-difference absorption-torque average value and the engine torque average value during shifting. From the ratio of the actual clutch capacity and a demanded clutch capacity, μ-correction-coefficient calculation means 130 calculates a μ correction coefficient. By using a control correction amount calculated on the basis of the μ correction coefficient, a transmission control unit 100 drive-controls a first clutch CL1 and a second clutch CL2. Thus, correction on the clutch capacity is performed during running.

Abstract: There are disclosed a method of and an apparatus for regulating the operation of a friction clutch or another torque transmission system in the power train of a motor vehicle. The regulation is such that the operator of the vehicle is informed of a prevailing or impending condition which entails or is about to entail damage to the system or to the entire power train. Such situation can arise in response to excessive and/or prolonged slip of abutting friction surfaces in a friction clutch, overheating of one or more parts of the system for any other reason(s), as a result of improper selection of the transmission speed for starting of the vehicle and/or due to excessive wear upon the friction linings and/or other parts. The remedial undertaking can include such regulation of the system that the ride become uncomfortable to the occupant(s) of the vehicle and/or automatic elimination of the cause(s) of unsatisfactory torque transmission.
