DaimlerChrysler engineers have come up with a special accelerator pedal that alerts the driver when to slow down – by vibrating.

The gadget monitors road and traffic conditions and causes the accelerator pedal to vibrate slightly for the driver to take his or her foot of the accelerator.

In trials with 70 volunteers using a prototype automatic S-Class Mercedes Benz, the pedal was found to potentially save motorists plenty of money as it showed an 11 per cent decrease in fuel consumption.

A computer accesses information supplied by a GPS to determine the car’s position t and monitor the gradients and speed limits, and triggers the reaction. Information is also provided by radar that measures the distance to the vehicle ahead.

Traffic lights and other obstacles are great contributors to late braking which results in great quantities of fuel being wasted. Tests, however, found that vibration was chosen because drivers reacted up to seven times faster to the vibrating pedal than to a dashboard light.
