Abstract:
1. A method for controlling an electric vehicle having a traction motor connected to a driveline during a vehicle wheel torque reversal comprising: controlling traction motor output torque through a region surrounding the vehicle wheel torque reversal to mitigate torque disturbances in a driveline, wherein the region is determined using a relationship between driveline input torque and driveline output torque and is bounded by a zero input torque and a zero output torque, wherein the relationship between driveline input torque and driveline output torque uses a gear ratio across the driveline, and wherein the region is bounded by zero driveline output torque such that the region is entered when driveline torque input causes a less than zero driveline output torque when the driveline is in a drive configuration.
