Abstract

The system has steering cylinders and drive units comprising an electrical machine (206,208) connected to a hydraulic machine (210,212). The first and second hydraulic machines are arranged for flow communication with a piston side (214) of the first steering cylinder (104), a piston rod side (216) of the second steering cylinder (105) and a piston side (218) of the second steering cylinder, a piston rod side (220) of the first steering cylinder respectively. An independent claim is also included for a method for controlling a frame-steered vehicle by means of steering cylinders.
