Cruise Control: Description and Operation




CRUISE CONTROL SYSTEM
The 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 his vehicle at a constant speed of 40 km/h (25 mile/h) or higher without depressing the accelerator pedal (constant cruising). The system also has such functions as to change the vehicle speed without operating the accelerator pedal (but using SET COAST and ACCEL RESUME switches), cancel cruise control (CANCEL switch) and resume the speed in memory automatically after cruise control is cancelled (ACCEL RESUME switch). The system mainly consists of a vehicle speed sensor, an actuator assembly incorporated with control module, cruise main switch, SET COAST switch, ACCEL RESUME switch and CANCEL switch, etc.
