The automatic driving system is controlled through a control panel by means of six buttons and eight leds which indicate the currently selected driving functionality. Since this is still in an early development stage, it is possible to change also a number of driving parameters which normally should be fixed and not changeable by the final user. Nevertheless, this option does not increase the interface complexity. For security reasons the user is required to press two buttons simultaneously for each command to be executed. The modifications in the system state are then notified to the user through vocal messages which confirm the reception and execution of the command. Moreover, for some commands whose execution is not instantaneous (such as the lane change command) an acoustic signal is also generated when the maneuver has been completed.
The emergency systems allows the driver to take the control of the vehicle in emergency situations in three different ways: tuning driving parameters (through the control panel buttons), temporarily taking over the system (by means of a joystick), completely taking over the system (by pressing a pedal close to the clutch pedal, the control panel buttons, or an emergency button close to the hand brake).
