Nissan connects navigation system and accelerator pedal

The system processes navigation data in real-time and does not only deliver the haptic feedback driver in pushing the pedal back against the driver's foot. It also automatically activates the brakes — smoothly, Nissan promises.
Another Nissan driver assistance system dubbed stability assistant synchronizes brakes, steering and motor control. In addition, it processes data related to steering, acceleration and braking activities as well as from a yaw rate sensor. If the system determines that the driver is too fast for the respective road segment, the assistant also automatically activates the brakes — individually for each wheel according to the respective curve radius.
Both assistance systems will be introduced into the Japanese market during the upcoming fall.

The idea of a synthetically generated force pushing back on the accelerator pedal if a vehicle is going too fast, is not new. Jet airplanes with the T-tail configuration and the engines in the rear (i.e. the Boeing 727) have "stick pushers", which will push the yoke forward if the aircraft is nearing a stall. The reason for this is, with that kind of airplane you don't want turbulence shed from a stalling wing to envelope the horizontal tailplane.
Now haptics are being used on cars as well.
