Abstract
A power management system is disclosed for an electrically driven vehicle, comprising a powertrain of at least two electric motors that can be selectively geared into the powertrain. The power management system is configured to indicate a level of mechanical power demanded from the powertrain, to estimate an electrical power demand from a respective one of the at least two electric motors as a function of the demanded mechanical power, and to activate or deactivate the respective electric motor in response to the mechanical power demand indicator. The power management system is further configured to (a) deactivate the respective electric motor when (1) the demanded mechanical power does not exceed a maximum value with the respective electric motor deactivated, and (2) the estimated electric power with the respective electric motor deactivated is lower than that with the respective electric motor activated; or otherwise (b) activate the respective electric motor.
