Patent ID: 7441625

Claim:
A self-propelled road-building machine, comprising: a driver's cab arranged on a chassis ( 4 ), a drive for moving the self-propelled machine, a steering means, a rotatable driver's seat ( 5 ) having a rotational position defined by an actual rotation angle μ and being provided in the driver's cab with an integrated control unit ( 6 ) for a driving operation, which generates actuation signals for the drive and the steering means in dependence on a direction of actuation of control elements of the control unit ( 6 ), characterized in that means for detecting the actual rotation angle μ of a rotational position of the seat and correct the direction components of the actuation signals of the control elements by an angle −μ such that the direction of actuation of the control elements coincides to the direction of movement of the vehicle in any rotational position of the seat.
