Patent ID: 7165643

Claim:
An industrial truck, comprising: a liftable and tiltable load-lifting device; a traction drive; operating drives for movement of the load-lifting device; a steering drive; a control device, wherein a calculation model based on vehicle-specific information for at least one of static, quasi-static, and dynamic tipping behavior of the industrial truck is stored in the control device; and a plurality of sensors connected to the control device for detecting physical variables relevant to at least one of the static, quasi-static, and dynamic tipping behavior of the industrial truck, wherein the control device is designed to determine a driving and load state based on the detected physical variables and the stored calculation model and is operatively connected to the traction drive, the operating drives, and the steering drive such that, depending on the driving and load state determined, corrective interventions to maintain or increase the tipping stability are carried out, and wherein in the control device, at least the following driving maneuvers which are critical to tipping are monitored: braking whilst travelling forward with the vehicle being inclined forward, accelerating whilst reversing with the vehicle being inclined forward, braking out of reverse travel on a bend with the vehicle being inclined perpendicular to a tipping axis, and accelerating forward on a bend with the vehicle being inclined perpendicular to the tipping axis.
