Abstract

A circuit arrangement is proposed which serves for controlling a gear shift display of a motor vehicle drive system, which is coupled to a multi-step transmission. The circuit arrangement comprises a computer (19), to which various operating data such as the opening angle (@) of the throttle valve (15), the engine speed (n1) and the output speed (n2) of the transmission (11) are fed. The operating data are compared with the limit values for economic operation of the engine (11) filed in a memory (24). The limit values are selected so that in the event of a difference between the measured and the stored data exceeding the limit values the computer (19) delivers an electrical signal to the display unit (25) for shifting the transmission (11) into a more economic gear for the same tractive force. A visual signal indicates to the driver of the motor vehicle by way of the gear shift display (25) that a more economic operation is possible by shifting the transmission up. <IMAGE>
