System for control of a distance of approach between adjacent moving vehicles, has a data recorder for storing the control mechanisms

摘要

Distance control device takes temporary control of vehicle acceleration or slowing down mechanisms when the vehicle becomes too close to a nearby vehicle. The control device works by comparing the actual distance with a theoretical distance for the driving conditions and is also capable of predicting a too small distance before it occurs by calculation, for example, of the rate of acceleration, etc. Independent claims are made for both a process for maintaining a safe distance from a nearby vehicle and a device for measurement of one or more physical constants from which appropriate control actions can be determined.
