Agricultural work vehicle with air-suspended driver's cab and GPS guidance system

Abstract

An agricultural work vehicle (2) with a chassis (6) which, in operation (B), has a driving position (FP) on the ground (4), with a driver's cab (12) which is movably mounted on the chassis (6) by means of at least one air spring (14a,b), wherein each of the air springs (14a,b) can be deflected by a respective current spring length (FLa,b) along a spring travel (16a,b) and the spring length (FLa,b) is correlated with a relative position (R) between the driver's cab (12) and the chassis (6), wherein the respective air spring (14a,b) contains a sensor (20a,b), and the spring length (FLa,b) is represented by its sensor signal (22a,b) and the sensor signal (22a,b) is provided in the vehicle (2), with at least one GPS sensor (26) which is fixedly attached to the driver's cab (12), wherein a GPS sensor (26) the GPS location position (GO) determined by the GPS sensor (26) in the vehicle (2) is provided, includes a lane guidance system (30),which is set up to determine the driving position (FP) based on the GPS location position (GO) by transforming the GPS location position (GO) to the driving position (FP) of the chassis (6), taking into account the relative position (R) based on at least one of the sensor signals (22a,b).
