Control system and method for controlling operation of an internal combustion engine

A control system for controlling operation of an internal combustion engine, the control system comprising at least one controller and memory associated with the at least one controller, the control system being configured to:

• receive a first request signal indicative of a first torque demand;
• determine a schedule defining an opening timing and a closing timing of an intake valve of a cylinder of the internal combustion engine in dependence on the first torque demand;
• cause the intake valve to open in accordance with the schedule;
• and
• during a period in which the intake valve is open:
• receive a second torque request signal indicative of a second torque demand different than the first torque demand,
• determine an updated schedule defining an updated closing timing of the intake valve in dependence on the second torque demand, and
• cause the intake valve to close in accordance with the updated schedule.
