Control arrangement for an engine and a hydrostatic transmission of a vehicle

Abstract:

A control arrangement for use in a drive arrangement of a vehicle includes an engine, a hydrostatic transmission, a load sensing means configured to detect a load on the engine, and an engine speed controller for controlling the engine. The arrangement further includes a pressure control means configured to act on a pressure in the hydrostatic transmission and a drive controller. The load sensing means generates a first signal, and based on the first signal, the drive controller generates a second signal for the engine speed controller and the pressure control means.
