[0006] The common shortcoming of previous known method is: not collect actual inclination in a direct way
This is neither reliably perceptible by previously known devices nor by the driver of the vehicle

Embodiment Construction

[0033] exist figure 1 A truck 1 with a device 8 according to the invention is shown in simplified form in . The vehicle shown has a vehicle body 2 on which a pivotable body 3 is mounted. The vehicle body 2 is connected to a chassis 4 which, in this illustration, includes an axle 5 , spring elements 6 and wheels 7 . figure 1 The position of the vehicle corresponds to driving or parking on a sloping ground with an inclination angle α, and the spring element 6 has a length suitable for driving operation. In view of the method according to the invention, this location is assumed to be the starting point for starting the method.

[0034] exist figure 2 shown in figure 1 The same vehicle as in . In this illustration, the spring element 6 is lowered to a minimum length x 0 . In this way, the center of gravity of the vehicle 1 is then shifted as close as possible in the direction of the axle 5 of the vehicle 1 and as close as possible to the center of the support surface. ...

Abstract

The present invention relates to a device (8) and a method for improved automatic ride level control of utility vehicles on an inclined underlying surface. In particular, the invention relates to the use of a lateral acceleration sensor (15) for sensing the inclination of a utility vehicle in the stationary state or with a reduced speed in conjunction with a chassis (4) of adjustable height.

Description

technical field [0001] The invention relates to a device and a method for automatically leveling a truck having a body, in particular with a body pivotable about a longitudinal or transverse axis, the device having There are devices for level adjustment, which have a length-adjustable spring element and a control unit. Background technique [0002] Trucks (hereinafter also referred to as "vehicles" for the sake of readability) that are on or move on inclined surfaces are subject to an increased risk of tipping over, especially when the center of gravity of the body is high. The risk of tipping over is increased especially for vehicles on which a pivotable body is mounted on the body, such as dump trucks or cranes. If the pivoting of the body is performed while the vehicle is on a sloping ground and the vehicle body is thereby tilted sideways, and the pivotable body moves towards the vehicle tilting direction, this also causes the center of gravity of the body to move toward...
