摘要：An improved system for synchronizing the output speed of an engine with thatnecessary at the next expected gear to achieve a desired speed ratio updates andmonitors the currently engaged gear. In this way, the system improves upon priorsystems that attempted to \"count\" to determine the currently engaged gear. Moreover,the system provides an operator with a shift intent switch that allows the operator topredict an upshift or a downshift as the next shift. The system calculates what the nextexpected gear will be based upon this indication. Once the next expected gear is known,the speed ratio at that gear is determined. Once the transmission is moved to neutral,the synchronization speed for the engine is then determined by multiplying the currenttransmission output speed with that next speed ratio. The engine control drives theengine speed to achieve synchronization speed ratio. The determination is updated as thetransmission speed changes. The operator completes the shift with a manual stick shift.
