Abstract
A transmission control is disclosed for a road vehicle for the determination of shift signals on downhill slopes. The invention includes a device for the determination of the stationary or constant speed drive torque M.sub.stat, which is necessary for the unaccelerated drive of the vehicle. The transmission control also includes a downhill gear classification device to coordinate the selection of a gear which is suitable for the downhill slope in question with a torque comparator in which various values of the stationary torque M.sub.stat are classified with the suitable downhill gear i.sub.x. A blocking element prevents a gear shift if a gear to be engaged by a shift command transmitter is higher than the suitable gear with the transmission ratio i.sub.x.
