    • PURPOSE: A constant speed driving system which can selectively turn a constant speed maintaining system on or off is provided to maintain constant speed driving by operating a throttle valve. CONSTITUTION: A constant speed driving system comprises a RPM sensor(110), a timer(120), a controller(130) and a display unit(140). The RPM sensor senses the current RPM. The timer senses the time to accelerate of RPM. The controller is applied with a signal of the RPM sensor and timer. The controller computes the accelerating time comparison RPM value. The controller determines fast acceleration and fast departure by comparing a calculated value with the current speed and vehicle piston displacement. If the value calculated with the controller is recognized as the fast departure value, the display unit informs fast acceleration and fast departure to an operator.
