Abstract
Apparatus for controlling the speed of an automobile in which the speed is maintained at a preset speed when a resume switch is manipulated. A memory stores data corresponding to the preset speed. The difference between the preset speed and the actual speed of the automobile is detected and this difference is employed to switch the reduction ratio of transmission gears of the automobile. The reduction ratio is increased when the actual speed becomes a predetermined speed less than the preset speed and when a predetermined condition is established. The predetermined condition is, for example, a condition in which the actual speed is less than the predetermined speed, the actual degree of acceleration is less than the predetermined degree of acceleration, or a predetermined time period elapses after the resume switch is manipulated.
