MONITORING TRANSMISSION SPEED CONTROL REQUEST FOR IMPROVED SHIFT QUALITY

摘要

A vehicle control system and method utilize a transmission control module configured to generate a first target speed for a torque generating system for executing a downshift of an automatic transmission and a torque generating system control module configured to determine a second target speed for the torque generating system for executing the downshift of the automatic transmission, determine upper and lower target speed limits for the torque generating system for executing the downshift of the automatic transmission, based on the first and second target speeds and the upper and lower target speed limits, determine a final target speed for the torque generating system for executing the downshift of the automatic transmission, determine a target torque output for the torque generating system based on a current speed of and the final target speed for the torque generating system, and control the torque generating system based on the target torque output.
