Abstract

An electronic circuit arrangement (20) for the actuation of an overdrive (23) in a change speed gear (22) of a motor vehicle driven by a combustion engine (21) is proposed in which the overdrive is automatically switched in or out in accordance with different predetermined threshold values of the inlet manifold negative pressure ( DELTA P). To avoid operation at low revolutions or over revving of the combustion engine, engine speed nM or vehicle speed limiting values are provided which produce a switching pattern for the switching over of the overdrive (23) by means of a logic gating circuit (33, 34, 35). Finally, it is guaranteed that the overdrive (23) can only be switched in when fourth gear is engaged. <IMAGE>
