A method and to a control system 208 for controlling movement of a vehicle to provide vehicle creep, the vehicle comprising an engine 202 and an electric traction motor 212, the control system comprising one or more controllers, wherein the control system is configured to: while a torque path 220 between the engine and a first set of vehicle wheels (FL, FR) is disconnected, control the electric traction motor to provide tractive torque to a second set of vehicle wheels (RL, RR) to automatically move the vehicle to provide electric vehicle creep, wherein 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, wherein the mathematical model is dependent on one or both of: an operating temperature associated with torque converter fluid, and a simulated gear ratio for an automatic transmission operable to provide vehicle creep in different forward gears and/or different reverse gears.
