  • Patent number: 8725335
    Abstract: Methods and apparatus are provided for torque control in an electric all wheel drive (e AWD) vehicle. The apparatus is a system having at least one propulsion system capable of determining a desired torque command and torque capability data for a primary and secondary axle. Also included are one or more active chassis systems capable of providing chassis system data and a processor coupled for processing the desired torque command, the torque capability data and the chassis system data to provide a maximum torque limit and a minimum torque limit for the secondary axle. In this way, at least one propulsion system processes the desired torque signal and the maximum torque limit and the minimum torque limit to provide an electric motor torque command and an engine torque command for the eAWD vehicle. A method for torque control in an eAWD vehicle is also provided.
