    Automotive cruise control systems are used to hold the vehicle speed steady at a set value especially in long runs to prevent driver fatigue. After switched “ON” by the driver, this system takes the control of the gas throttle using an electronically controlled stepper motor, and keeps the vehicle speed constant. This system requires speed sensors to measure the controlled vehicle speed. a) Identify basic elements of the cruise control system. (Reference input, output, actuator, controller, sensor, plant) b) List...
