| 摘要 |
Utility vehicle, especially a heavy goods vehicle or bus, comprises a steerable front axle (1), and a driven rear axle (4) assigned a forward or trailing axle (7), which can be raised and lowered by a lifting device. The utility vehicle also comprises a gear selection sensor (20) and a front wheel steering angle sensor (21) whose measurement values are fed to an electronic control device (19). In the case of shunting operation of the utility vehicle determined by speed selection, a speed below the fixed speed threshold VR max and a steering deflection of the front wheels (2, 3) via a pre-determined minimum deflection angle alphaR min, the lifting device (16-18) lifts the additional support function, i.e. raises the forward or trailing axle. An Independent claim is also included for a process for operating a utility vehicle.
