A method and a control system for controlling movement of a vehicle to provide vehicle creep, the vehicle having an engine and an electric traction motor, and the control system having one or more controllers. The control system is configured to: while a torque path between the engine and a first set of vehicle wheels is disconnected, control the electric traction motor to provide tractive torque to a second set of vehicle wheels to automatically move the vehicle to provide electric vehicle creep. The electric vehicle creep is controlled by a mathematical model of engine creep torque that would be provided by the engine when the torque path between the engine and the first set of vehicle wheels is connected.
