1. An engine control system in a vehicle comprising:
- a variable displacement internal combustion engine;
a controller for controlling the displacement of said variable displacement internal combustion engine;
an accelerator pedal position sensor electronically coupled to said controller; and
wherein said controller receives pedal position information from said accelerator pedal position sensor and characterizes the type of driver operating the vehicle;
wherein said controller using said driver characterization determines when to operate said variable displacement internal combustion engine in a partially-displaced operating mode.
