A second generation automotive speed control system using electronic circuits to perform the necessary logic and memory functions is described. Important considerations, such as performance and environmental factors, are discussed in relation to their design implications. Component function and system operation are covered using generalized circuit concepts. The unique Philco-Ford electronic speed control system is decribed in detail. IT IS THE INTENT of this paper to describe the design factors, functional elements, and general operation of an automatic electronic speed control system for motor vehicle use. Automatic electronic speed control is a feedback control system that has the ability to hold the vehicle speed constant for varying load conditions. This system relieves the driver of the boring task of maintaining the vehicle speed and allows him to concentrate on more significant aspects of his driving.
