Title: (EN) A transmission control system for a vehicle
Abstract:
(EN) A CVT controller (22) of a vehicle (10) communicates with the engine management system (EMS) (20). When a manual shift between simulated fixed ratios is performed, the CVT controller (22) sends a shift signal to the EMS (20) which alters the engine torque for the duration of the shift in order to simulate a manual shift to provide, for example, a sporty feel to the vehicle (10).
