Abstract
A vehicle includes an engine, a transmission, and an electric machine configured to provide drive torque and regenerative braking torque. The electric machine is selectively coupled to the engine via a clutch. The vehicle additionally includes a torque converter with an associated bypass clutch coupling the electric machine and transmission. The bypass clutch has an associated torque capacity. The vehicle further includes a controller. The controller is configured to, in response to a braking request indicative of an anticipated regenerative braking request, increase the torque capacity prior to the regenerative braking event by a quantity corresponding to an anticipated regenerative braking torque associated with the anticipated regenerative braking event.
