Electric drive module and method for operating an electric drive module

摘要

An electric drive module and a method for switching a drive module between a torque vectoring and at least one propulsion mode are provided. A controller can switch the drive module to the torque vectoring mode when a first set of conditions is met and can switch to one of the propulsion modes when either a second or a third set of conditions is met. The first set can include: torque requested by an operator is less than or equal to a first demand threshold; and a vehicle velocity is greater than or equal to a first velocity threshold. The second set can include: the vehicle velocity is less than a second velocity threshold; and a vehicle lateral instability is less than or equal to an instability threshold. The third set can include: the torque requested by the operator of the vehicle is greater than a second demand threshold.

1. A method for controlling transmission of power to a set of vehicle wheels, the method comprising:
providing a drive module for powering the set of vehicle wheels, the drive module being operable in a torque vectoring mode and at least one propulsion mode; switching the drive module to the torque vectoring mode when a first set of conditions is met; and switching the drive module to a propulsion mode of the at least one propulsion mode when either a second set of conditions is met or a third set of conditions is met; and wherein the first set of conditions includes: a torque requested by an operator of the vehicle is less than or equal to a first predetermined demand threshold; and a velocity of the vehicle is greater than or equal to a first predetermined velocity threshold; wherein the second set of conditions includes: the velocity of the vehicle is less than a second predetermined velocity threshold; and a lateral instability of the vehicle is less than or equal to a predetermined instability threshold; and wherein the third set of conditions includes: the torque requested by the operator of the vehicle is greater than a second predetermined demand threshold.
