摘要： 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.

摘要： A transmission disconnect clutch assembly and method are provided. The clutch assembly operates to place the transmission in a low-loss state, by decoupling the base transmission from the differential gearing, thereby maximizing fuel economy and increasing efficiency. The transmission disconnect clutch assembly may be a dog clutch assembly, which may include a dog clutch hub, a clutch apply plate, and a synchronizer. When the dog clutch is disengaged the vehicle may operate in EV mode, propelled by an electric motor and rear e-axle. When the dog clutch is engaged the vehicle may operate in hybrid mode, propelled by torque transmitted to a front axle by an engine and the torque transmitted to the rear e-axle by the electric motor. A method for transitioning a vehicle between EV mode and hybrid mode, as well as a method for transitioning a vehicle between hybrid mode and EV mode are also provided.
