Cruise Control

Cruise control is a driver ease feature which maintains engine speed without the driver keeping their foot on the accelerator pedal. It does so by locking the throttle body's butterfly valve in the postion it is in when the driver presses the cruise control button.

Drive-by-Wire Cruise Control

Because the throttle body on a Drive-by-Wire vehicle is operated by an electronic actuator, the cruise control system is less complicated, only requiring the computer to stop moving the actuator.
