The invention relates to a vehicle, comprising a vehicle floor, three vehicle wheels and a surroundings monitoring device comprising a plurality of surroundings sensor units, in particular laser scanners, each of which has a continuous monitoring angle range in a horizontal plane below the vehicle floor, wherein the surroundings monitoring device comprises two surroundings sensor units which are arranged under the vehicle floor, within the plan view contour of the vehicle, such that the monitoring angle ranges thereof overlap one another in part and define a common horizontal scanning region in which gaps or shadowing in the monitoring angle range of a particular surroundings sensor unit, within the plan view of the vehicle, are captured by the monitoring angle range of the other surroundings sensor unit, such that the surroundings monitoring device offers 360&#xb0; all-around monitoring around the vehicle.

Vehicle comprising a surroundings monitoring device

A method for determining or estimating a load weight of a load () carried by a commercial vehicle, in particular by an industrial truck such as a forklift truck (), comprises: A commercial vehicle () comprising a control system () carrying out a method of this kind is also provided.

Vehicle wheel speed-based determination or estimation of a load weight of a load carried by a commercial vehicle

An industrial truck and a method for its delivery are proposed, the mobile base of the industrial truck being transported to the delivery destination on a load transport vehicle. At the delivery destination, an operating device that is also supplied is used as a mobile operating device for issuing control instructions for the traction operations of the base vehicle, in order to drive the base vehicle with its own drive units off the load transport vehicle over a ramp or the like and thus to set it down.

Industrial truck

The invention relates to a steering actuation device for a vehicle, in particular for an industrial truck, having an operating element for inputting steering commands by exerting torques on the operating element, having a sensor arrangement for monitoring the steering command input state of the operating element and having a control device for converting the steering command input data detected by the sensor arrangement into control information for a steering drive apparatus of a wheel, which can be steered, of the vehicle, the sensor arrangement detecting the respective steering command input state of the operating element by means of monitoring the elastic material deformation, in particular torsion, of an element, which is subjected to elastic deformation by means of a steering command input torque on the operating element and is coupled to or associated with the operating element.

Rotation angle sensor, in particular for an electrical steering system of an industrial truck, in which two magnetic field sensitive sensor elements are arranged on orthogonal axes and a permanent magnet is attached to a shaft extending through the axis intersection point and the output signals X, Y of the sensor elements are given to an evaluation unit, which determines from the two output signals X, Y the rotation angle value by means of a function saved in the evaluation unit, characterized in that for a plurality of predetermined values of one of the output signals X or Y associated ideal values calculated from the geometrical relationship of the sensors of the other output signal Y, X are saved in the evaluation unit, the measured values of the other output signal Y, X are compared with the ideal values and a warning or stop signal is created if the difference between the measured and ideal value reaches a predetermined amount.

Rotation angle sensor, in particular for an electrical steering system of an industrial truck

The invention relates to an industrial truck having a first load-bearing component () and a second load-bearing component () which are provided such that they can move in relation to one another for the purpose of carrying out a conveying movement, a sensor scale () being provided on one of the load-bearing components () (scale load-bearing component) for the purpose of detecting the relative movement between the two load-bearing components (), and a sensor (), which is designed to detect the sensor scale (), being provided on the respective other load-bearing component () (sensor load-bearing component). The industrial truck is characterized in that the sensor scale () is designed integrally on the scale load-bearing component () such that a section () of the scale load-bearing component () itself is the sensor scale ().
