Abstract:
A vehicle has an engine, an upstream clutch, an electric machine, a downstream clutch, a transmission gearbox, and a controller. The controller is configured to: (i) control engagement of the downstream clutch, (ii) monitor a vehicle torque, and (iii) control electric machine torque to a designated rate when the vehicle torque changes direction and the electric machine is operating. A method for controlling a hybrid vehicle includes engaging a clutch downstream of the electric machine, monitoring a vehicle torque, and controlling electric machine torque to a designated rate when vehicle torque changes direction and the electric machine is operating. A hybrid vehicle system has an electric machine and a controller configured to (i) control electric machine torque to a designated rate within a time zone, and (ii) control at least one of the electric machine torque and an engine torque to meet driver demand outside of the zone.
