Bosch says it has developed a technical aid for accelerators, which alerts drivers through vibration if they are using the pedal too heavily.
“The Bosch active gas pedal helps drivers save fuel – and alerts them to potentially dangerous situations as well,” said Bosch Gasoline Systems division president, Stefan Seiberth.
“And if the vehicle has an assistance system, the pedal becomes a warning indicator: coupled with the navigation system or a camera that recognises road signs, the Bosch gas pedal gives drivers a haptic warning signal if, for example, they are approaching a dangerous bend at too high a speed.”
Bosch maintains the feedback drivers receive from the pedal allows them to reduce fuel consumption by as much as 7%.
The supplier claims this is possible because the gas pedal can be networked with other automotive functions, such as the transmission.
Up to now, the only indication drivers have had of the best time to shift gear has been in the form of small arrows on the instrument display. The active gas pedal comes with the option of a palpable indication of the best time to shift gear.
“The pedal tells the driver when the economy and acceleration curves intersect,” added Seiberth.
“If the driver still wants to accelerate some more before shifting gear, however, applying a little extra pressure is enough.”
