A control system 50 for controlling a powertrain 22 of a vehicle is configured to receive a desired occupant comfort level (62) and to receive occupant excitation information 63 indicative of movement of the vehicle and/or movement of an occupant of the vehicle. The control system is configured to determine an occupant comfort level (53) based on a time-average of the occupant excitation information and to determine a target vehicle speed in dependence on the occupant comfort level and the desired occupant comfort level. The control system is configured to output a vehicle speed control signal 71 based on the target vehicle speed. The control system is configured to output the vehicle speed control signal independent of the target vehicle speed during an override period when an accelerator of the vehicle is actuated (67), and wherein, following the override period, the control system is configured to determine an updated value of the occupant comfort level by ignoring occupant excitation information for at least part of the override period.
