Abstract
A vehicle propulsion system includes an engine arranged to output a first torque to a driveshaft and an electric motor arranged to output a second torque to the driveshaft. The vehicle also includes an automatic transmission arranged to receive an input torque from the driveshaft. The vehicle further includes an exhaust system to output combustion byproduct from the engine. A vehicle controller is programmed to, during deceleration, cause the engine to apply a negative first torque to increase an audible exhaust system sound. The controller is also programmed to activate the electric motor to output a positive second torque such that the input torque to the automatic transmission does not exceed a transmission torque threshold during deceleration.
