INTERACTIVE TRANSMISSION SHIFT TECHNIQUES

摘要

A method for interactive transmission garage shifts includes receiving a request for a transmission garage shift; controlling the transmission to bring the vehicle to a stop state based on determining that the vehicle is rolling backwards on a grade above a predetermined grade threshold and at a speed below a predetermined speed threshold; controlling an electric park brake (EPB) to hold the vehicle at the stop state; controlling the transmission to engage a dog clutch so as to place the transmission in a forward drive gear; and controlling the EPB to i) deactivate if the dog clutch is determined to be engaged, or ii) maintain activation to maintain the vehicle at the stop state if the dog clutch is determined to be disengaged.
