Abstract

PURPOSE:To improve excessive responsiveness by providing two vehicle speed detecting means for detecting each rotating speed of a speedometer driving cable and a transmission output shaft. CONSTITUTION:First and second vehicle speed detecting means 2, 3 detect each rotating speed of a speedometer driving cable and a transmission output shaft and generate first and second vehicle speed pulses in order. And, the sums of each period of each series of first and second vehicle speed pulses are determined 4, 5 and the ratio (period sum ratio) of these is determined 6. Also, the present vehicle speed is determined 7 in accordance with the second period sum and period sum ratio, and the period sum ratio and the present vehicle speed are stored 8 as a set ratio and a pseudo-set vehicle speed. And, the difference between the present vehicle speed (pseudo-vehicle speed) and pseudo-set vehicle speed is determined 9a while a pseudo-acceleration is determined 9b based on the pseudo-vehicle speed, and a prime mover is controlled by a control means 9c to keep the present vehicle speed at the set vehicle speed in accordance with the determined data.
