Abstract

PURPOSE:To maintain the vehicle speed constant and as well to simply carry out the constant speed control at a low cost, by controlling the supply amount of fuel fed to the engine with the use of a computer in accordance with a set vehicle speed and an actual vehicle speed. CONSTITUTION:A fuel preference type electronic-controlled fuel supply device comprises a position sensor 22 for an accelerator pedal 20, pressure sensors 24, 26 for respectively detecting the pressures upstream and downstrem of a throttle valve 12, and a computer 28, and controls the air-fuel ratio on the basis of various data of the engine 10. Upon maintaining the vehicle speed constant, an arbitrary set speed is at first set, and this set speed is compared with an actual vehicle speed detected by a vehicle speed sensor 30. If both speeds are not equal together, and adjusting amount is computed in accordance with the difference between both speeds, and is added to the fuel supply amount which is then fed to the engine 10. With this arrangement, the actual vehicle speed is subjected to the constant speed control with the set speed.
