1. A simulated shift system for a battery electric vehicle (BEV), the simulated shift system comprising:
a set of sensors configured to monitor a set of parameters indicative of driver input by a driver of the BEV; and
a controller configured to:
control an electric drive module (EDM) of the BEV, the EDM comprising a gear system connected to an electric motor and being configured to output drive torque to a driveline of the BEV, wherein the EDM is a dual or dual-speed EDM and the gear system has at least two gears and the EDM has a transmission control module (TCM) for controlling actual shifting between the at least two gears;
receive the monitored set of parameters; and
based on the monitored set of parameters, selectively control the EDM to adjust drive torque output therefrom to simulate transmission shift operations of a predetermined conventional automotive automatic transmission having four or more speeds.
