The invention relates to a method and a device for open-loop control of the speed of an electrically driven toy car on a lane-guided racetrack. By means of a hand-actuatable closed-loop control device, the speed of the toy car can be adjusted to at least two speed levels. To adjust the magnitude of the first speed level as a fraction of the second speed level, the closed-loop control device is preferably programmable so that via the open-loop control device, the speed of the toy car is adjusted between a zero position and the first speed level and, after actuation of a selection switch, the speed of the traveling toy is adjustable between the zero position and the second speed level. The invention permits the adjustment of partial speeds of a toy car on a racetrack without using a transformer.
