  • Patent number: 9783061
    Abstract: The present teachings provide a method for controlling transmission of power to a set of wheels of a vehicle. The method can include providing a drive module configured to provide an amount of drive torque for powering the set of vehicle wheels. The method can include determining a yaw rate of the vehicle and a first set of vehicle parameters. The method can include determining a reference yaw rate of the vehicle based on the first set of vehicle parameters. The method can include calculating a yaw rate error based on the yaw rate and the reference yaw rate. The method can include reducing the amount of drive torque provided by the drive module to the vehicle wheels based on the yaw rate error.

  • Patent number: 9637022
    Abstract: 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.
