Abstract

The electronic equipment for cars are very important enhancement mainly if they regard the security of driver and passengers. One of them, more and more popular in the recent period, is the automatic speed regulator, also known as "cruise control". The proposed article deals with a system in which speed sign signals, available on the road, can interact with an on-board car receiver, to influence the cruise control available on the car.

Adaptive Speed Regulator Device

The proposed solution deals with a system based on radio frequency devices, some situated along the roads that are able to transmit signals to the device embedded on car. The device receiver on car can broadcast the current speed limit policy (e.g. due to fog/incident current speed limit is X km/h) and interact with automatic speed regulator, which can adapt to the changed policy in automatic or semi-automatic way (e.g. requesting driver acknowledge).

In this way it can automatically decrease the car speed if it's too high in relation to the actual external conditions, according with the new threshold.

The radio frequency devices along the road could be also centrally dynamically regulated so to reflect not only changes in street conditions but also, for example, in weather ones, traffic forecast or accidents ahead, etc.

With a more articulated central management of the dynamic regulation of devices, a further benefit of this system could be, for example, the regulation of vehicles flows on highway. If forward on the same direction, on the highway, there is a certain density of vehicles or some car queues are already present, the adaptive speed limiter could decrease the speed of the approaching vehicles so that to relieve the pressure on the busy streets.

A possible extension to current proposal, is to adapt to cases in which legacy speed signs are in place, not yet able to emit a RF inform...
