ABSTRACT:
A tilt control method includes a tilt control step for automatic control of the tilt (α) of a tilt device (1) by at least one electronic tilt sensor (2) based on gravitational force (G) and by a tilt control device (5), and a sensor test step which is carried out automatically at a test initiation signal, and in case of a malfunction, supplies an error signal (Θ) which prevents the tilt control step from being carried out.
