  • Publication number: 20220381603
    Abstract: Disclosed is a load detection device and method using the same. In one example, the device includes a height-level measuring unit configured to determine a height level of a vehicle and to generate at least one height-level signal that characterizes the height level. A position-measuring unit is configured to determine the position of the vehicle relative to the mid-point of the earth and to generate at least one position signal that characterizes the vehicle position. An evaluation unit is coupled to the height-level measuring unit and to the position-measuring unit. The evaluation unit is configured to determine a mass of a load of the vehicle, taking into account the height-level signal(s) and the position signal(s). The device can be used to determine the mass of the load, which may include a number of persons.

  • Publication number: 20220363100
    Abstract: Disclosed is a chassis component (1, 38) having a measuring device (9) for determining a relative position of two chassis components connected movably with one another. For example, a first chassis component is a joint (2) with at least one rotation axis (8) and a second chassis component is a structural component (3), the structural component (3) being mounted by means of the joint (2) so that it can pivot around the rotation axis (8) of the joint (2). The measuring device (9) has a signal emitter (13) and a sensor device (10, 28) with a signal receiver (21), where the sensor device (10, 28) is arranged on the structural component (3) and the signal emitter (13) is arranged on the joint (2). To improve an arrangement of the sensor device (10, 28) on the structural component (3), the sensor device (10, 28) extends through a through-opening (11).

  • Patent number: 11376919
    Abstract: A chassis component (16), with a first end section (17) and a second end section (18) and a connecting section (19) is arranged between the two end sections (17, 18). At least one ball joint (21) is associated with one of the two end sections (17, 18), and a sensor device (22) is associated with the ball joint (21). A first sensor element (23) of the sensor device (22) is arranged on the end section (18) that has the ball joint (21) and a second sensor element (24) is arranged on an inner joint component (25) of the ball joint (21).

  • Patent number: 11378381
    Abstract: A magnetic field sensor has a magnet (M1) that produces a magnetic field with a magnetic field axis (f), has a magnet axis (a) and is held in a component (4) that can move about at least one axis and has a component axis (b). Also a method for mounting a magnet (M1) of a magnetic field sensor. The magnet (M1) is held in the component (4) in such a manner that the magnetic field axis (f) coincides, as closely as possible, with the component axis (b). A deviation of the magnetic field axis (f) from the magnet axis (a) is measured, and the angle of deviation (?) is corrected during the mounting of the magnet (M1) in the component (4).
