Abstract
A motor vehicle propulsion system, an engine control system, and a method for starting an engine of a motor vehicle system are provided, which are configured to request an engine restart after stopping the engine, decrease a K-factor in a torque converter coupling within 1.5 seconds of requesting the engine restart, and to increase the K-factor in the torque converter coupling to minimize the lash and disturbance between interconnecting components in a vehicle system during negative torque vehicle driving to positive torque propulsion system driving transitions where a torque converter exists.
