GEAR SHIFT SCHEDULING USING VARIABLE VALVE LIFT/ACTUATION

WIPO Patent Application WO/2018/191354

A3

A vehicle powertrain control technique includes obtaining, by a controller, a set of parameters each indicative of a gear shift operation for an automatic transmission. Based on the set of parameters, the controller detects whether a gear shift operation of the automatic transmission is imminent. In response to detecting that the gear shift operation of the automatic transmission is imminent, the controller (i) determines a desired reduction in powertrain output torque for performing the gear shift operation and (ii) controls the powertrain to temporarily reduce its torque output via a technique other than spark retardation. After reducing the powertrain output torque, the controller commands the automatic transmission to perform the gear shift operation. The temporary powertrain output torque reduction is achieved by controlling a variable valve control (VVC) system of an engine, such as commanding a lower valve lift profile, or decreasing power supplied to an electric motor.
