Improvements to Cruise Controls Utilizing Microprocessor Technology

A second generation digital cruise control system has been developed which boasts improved performance, more functions, lower cost and improved safety features.

This paper discusses the problems encountered with designing a digital cruise control system and some practical solutions. A unique method of measuring speed is described which provides an order of magnitude improvement in resolution over previous methods. A discussion of new features available is included and a comprehensive safety system featuring “exclusive-or” brake detection and “redundant brake” safety backup is also described.
