A self-propelled vehicle, eg a locomotive, has a control unit (13) incorporating a micro processor and a diesel engine (5) driving a pump (11) whose output is varied by unit (13) according to signals representing the speed of the engine and individual where motors (15) and the pressure differential between delivery and return lines (14, 17) which indicates whether the vehicle is pulling or being pushed by its load. The unit (13) compares, the speed of a driven wheel at one side of the vehicle with a reference speed for that side and additionally compares, the speed of a driven wheel at one side of the vehicle with the speed of a driven wheel at the other side, the pump output being increased or decreased should the comparisons indicate speed differences outside allowable tolerances. <IMAGE> |
