Control device for a vehicle driven by a prime mover by way of a stepped transmission

摘要

A control device for a commercial-vehicle stepped transmission is proposed which has the following devices: a family of engine characteristics 36 for determining the instantaneous drive torque MA delivered by the engine (36); a measuring device (16) for registering the acceleration s of the vehicle; a weight determination (30) for calculating the vehicle weight with the aid of the instantaneous drive torque MA and the acceleration s; a torque monitoring device (24) for calculating a stationary torque Mstat; and a transmission control (18) for comparing the stationary torque Mstat with a predetermined optimum torque Mopt. <IMAGE>
