Rear impact prevention signal controller for driving in fog has electronic controller with sensors for space in front of/following vehicle that derives speed-dependent distance values

摘要

The device has an electronic controller with sensors for the space immediately in front of and following the vehicle that determines distance limit values and/or speed differences relative to a vehicle and derives speed-dependent distance values and coverts these to sound and light signals at the correct time. Driver intervention is exercised with a rotary switch with priority to meet the various road traffic requirements.
