Abstract: A method of cruise control for a vehicle includes: checking for cruise conditions, determining whether the vehicle is in cruisecontrol mode, and if so, controlling the cruising speed of the vehicle until an exit signal is detected; checking the throttle deviation, to determine throttle stability; checking cruising speed, whereby if conditions for throttle stability are met, the speed deviation of the vehicle is calculated, and the cruising speed is set; if conditions for cruising have been met, issuing a cruising prompt message to the driver, and detecting actions of the driver, and if it is thereafter detected that the driver has released the throttle pedal, then entering the vehicle into cruise control mode whereby the vehicle speed is automatically controlled to the set cruising speed. A system is provided to perform the method. A cruise control which is low-cost, requires no control buttons, and offers a simple product structure is achieved.
