TORQUE COMPENSATION FOR AIR/FUEL SWITCHING

A vehicle includes one or more processors configured to select an air/fuel ratio for the engine that is different from the stoichiometric air/fuel ratio. The one or more processors are further configured to select a torque request for the engine, determine a load request for the engine based on at least the torque request and the selected air/fuel ratio, and determine an output to a throttle actuator based on the load request for the engine.
