Method and device for controlling functions of an occupational vehicle

摘要

A method and a device for controlling functions of an occupational vehicle (1) comprising a driving motor (2), a clutch (3), a service brake (13, 14) that acts upon the wheels (11, 12) of the vehicle, a working device (21), and a hydraulic pump (15) which supplies the actuators (32) of the clutch (3), the service brake (13, 14), and the actuators (19, 20) of the working device (21) with pressure, via hydraulic pressure pipes. In order to reduce the fuel consumption, distribute in an optimal and user-relevant manner, the hydraulic pressure generated by the pump (15), and facilitate operation of such a vehicle, the clutch (3) is automatically opened and the service brake (13, 14) is automatically closed when the load acting upon the working device (21) of the vehicle exceeds a preset threshold or is actuated so as to exceed the threshold.
