Nissan ECO Pedal helps fuel efficiency


Posted on September 26, 2008 12:00 AM

Ever since electronics found their way into cars, engineers have been able to provide more and more sophisticated systems to help drivers. ABS, EBD, Brake Assist and stability control systems would not be possible without electronics which operate at lightning speed to take activate various components. Likewise, fuel delivery has become much more efficient with electronic fuel injection (EFI) which can be varied to suit all kinds of driving conditions.

In 2009, Nissan will introduce yet another electronic system which can help drivers save fuel as they drive. Known as the ECO Pedal, it is the first of its kind in the world and is claimed to be able to improve fuel economy by 5 to 10% (according to Nissan’s own tests).

 

The ECO Pedal has a counter push-back control system which lets the driver know that he or she could be using more fuel than required. The system is fed data on the rate of fuel consumption and transmission efficiency during acceleration and cruising, and then calculates the optimum acceleration rate. When the driver exerts excess pressure on the accelerator, the system counteracts with the pedal push-back control mechanism.

Additionally, an eco-driving indicator in the instrument panel tells the driver of real-time fuel consumption levels to help improve driving behaviour. It will flash when it detects increased acceleration before reaching the fuel consumption threshold and finally turns amber to advise the driver of their driving behaviour.

The ECO Pedal system can be turned on or off according to the driver’s preference but why would anyone want it off?
 
In order to achieve reduction in C02 emissions, Nissan takes a “triple-layer” solution that encompasses vehicle technologies, driving behaviour and traffic conditions. The ECO Pedal supports the second-layer addressing driving behaviour and is among a range of eco-friendly technologies being pursued under the Nissan Green Program 2010. The company’s environmental roadmap aims at developing new technologies, products and services that can lead to real-world reductions in vehicle CO2 emissions, cleaner emissions, and recycling of resources.
