A system for assisting a vehicle (10) to travel at a steady speed, the system comprising: monitoring a signal indicative of a speed of the vehicle (10); monitoring a signal indicative of a state of an actuator (12) that is operable by a driver of the vehicle (10) to control an output of an engine (14) of the vehicle (10); a means to: determine a confidence level that a steady speed of the vehicle (10) is desired based on the signal indicative of a speed of the vehicle (10) and the signal indicative of a state of the actuator (12); interpolate between a normal actuator response map (56) and a modified actuator response map (60) in dependence on the confidence level, and translate the indicated actuator state into an engine output request in dependence on said interpolation, wherein the modified actuator response map (60) is arranged to damp a response of the actuator (12) relative to the normal actuator response map (56); and means for sending the engine output request signal to control an output of the engine (14). A corresponding method is also provided.
