Developing a Unique Collaborative System - "Optimization-Ware" Using a Novel Massive Data Retrieval/Management Approach.

A device for adjusting traveling speed of a motor vehicle includes traveling speed and acceleration PI-regulators cooperating via an operational condition control and a switching device with an electronic fuel metering system of a motor vehicle. The acceleration regulator and the traveling speed regulator are alternately activated in dependency on the selection of desired driving conditions, namely whether a traveling speed is to be reached or maintained. A high driving comfort is obtained by modifying initial and transition states of integral parts of output signals of respective regulators.
