Drive by Wire - Electronic Throttle Control
How it works
ETCS provides an all-electronic system able to detect throttle pedal position
Electronic Throttle Control is the technical name for what is known as 'drive by wire'.
In place of the conventional mechanical connection between the accelerator pedal and the engine throttle control, ETCS provides an all-electronic system able to detect throttle pedal position by means of a series of sensors. It then relays that information to a computer which instantaneously activates the throttle by means of a DC motor.
The control software works in harmony with the engine management system to provide smooth and responsive adjustments, which are directly proportional to driver input.
It is also fully integrated with the automatic transmission and cruise control software. This enhances the precision of these systems for maximum driver enjoyment.
