摘要： A vehicle includes an engine, an engine control module (ECM), and a dual clutch transmission (DCT) assembly. The DCT assembly has first and second input clutches, first and second gear sets selectively connected to the engine via the respective first and second input clutches, and a transmission control module (TCM). In executing a launch control method, the TCM receives a launch request, receives an actual engine torque, and determines the inertia and acceleration of the engine. The TCM then calculates a clutch torque for the particular input clutch used for vehicle launch as a function of the actual engine torque and the product of the inertia and the acceleration, compares the calculated clutch torque to the commanded clutch torque, modifies a torque-to-position (TTP) table depending on the comparison result, and transmits a clutch position signal to the designated input clutch to command an apply position extracted from the TTP table.

摘要： A propulsion system controller for a vehicle that includes a prime mover operable for generating an input torque on an input shaft, and a transmission connected to the prime mover that is configured to receive the input torque from the input shaft and produce an output torque on an output shaft. The controller is programmed to generate a torque phase ratio, rationalize the generated torque phase ratio, and submit a torque request to the prime mover that is based upon a desired output torque divided by the rationalized torque phase ratio.

摘要： A vehicle and method is provided. The vehicle includes systems and method for limiting the slip of the wheels. In an embodiment, the system holds the brakes based on an acceleration characteristic measured by a sensor. In another embodiment, the system includes a transmission controller that applies an adjustment to limit an amount of clutch slip as the clutch temperature to change in clutch performance to reduce wheel slip. In another embodiment, the system monitors wheel slip signal from a sensor and compares the wheel slip to a target slip value and controls clutch slip of the transmission clutch based to maintain engine output torque during acceleration. In another embodiment, in response to an anticipated vehicle launch event, a drive motor applies a first torque to the input shaft to adjust a gear lash of the differential unit.
