How A Cruise Control Works
Cruise Control Working Of Car Cruise Control History The cruise control system is also known by alternative names such as auto-cruise and speed control. A mechanical engineer by the name of Ralph Teetor in 1945, invented the Speedostat, which is a version of the modern cruise control system. The idea was conceptualized when Ralph observed a rotating driveshaft. Having knowledge of electronics he devised a counter and throttle actuator which was connected to the engine. Throttle position was varied by the actuator using a controller which sensed the rotations. The cruise control system is by default turned off, but can be activated by the user. Other than the on switch, there are switches for set, accelerate, resume, cancel and coast features. These first cruise control systems consisted of a control unit, driveshaft, control switch, brake cutoff switch, vacuum servo, wiring harness and vacuum lines.
