Cruise Control System Construction

Cruise Control System Construction

Cruise control system is a device which maintains a preset vehicle speed while driving at a high speed, e.g., on a highway. It allows the driver to drive at a constant speed of 40 km/h (25 mile/h) or higher without depressing the accelerator pedal. The system also has functions to change vehicle speed without operating the accelerator pedal (SET/COAST and RES/ACC switches), cancel cruise control (CANCEL switch) and automatically resume driving at the speed in memory when cruise control is reactivated (RES/ACC switch).

The system mainly consists of electric throttle body assembly, ECM, cruise control switches (MAIN (ON/OFF) switch, SET/COAST switch, RES/ACC switch and CANCEL switch), etc.
