Cruise control method monitors vehicle speed for a time period (e.g. monitors wheel speed / engine speed) and implements cruise control if detected vehicle speed is constant / uniform within predetermined limits, for a predetermined time period. The predetermined speed and time period can be variable, and may depend on engine conditions, running conditions, vehicle type, or driver preferences. Cruise control activation may depend on pre-requisite conditions including non-activation of clutch / brake, engine not at idle, engine speed / torque within certain range, vehicle speed above pre-set value, accelerator pedal displaced above pre-set value, or vehicle being in specific forward gears. Cruise speed may be adjusted by movement of accelerator pedal, though small movement may be ignored, and very large movement may deactivate cruise control. Cruise control implementation may be automatic. |
