  • Publication number: 20220326048
    Abstract: The present disclosure relates to a sensor assembly for simultaneously capturing an angular position and a torque of a rotatable shaft. The sensor assembly comprises, for determining the angular position, a main body, two additional bodies, which are arranged coupled for rotation on the main body, and two angle resolvers, which are arranged on a circuit board in the immediate vicinity of the additional bodies. In this arrangement, the angles of the additional bodies are determined by the angle resolvers and passed as an angle signal to an evaluation unit arranged on the circuit board. The sensor assembly further comprises a direct coating, which captures a torque signal from the rotating shaft and passes this signal over a connection line to the evaluation unit. The connection line has a section wound multiple times around the shaft to permit a rotation of the shaft by at least +/?900°.

  • Publication number: 20220214239
    Abstract: A method test an arrangement for measuring a torque acting on a steering shaft of a motor vehicle. The measurement is carried out using the inverse magnetostrictive effect. The steering shaft has an axis and at least two magnetization areas extending circumferentially around the axis. The arrangement comprises at least four magnetic field sensors for measuring an axial component of a magnetic field caused by the magnetization as well as by the torque. There are at least two combinations of at least two of the magnetic field sensors each, each of which is sufficient to measure the torque. First and second measurement values of the torque are determined with first and second combinations of the magnetic field sensors. The first measurement value and the second measurement value are compared, as a result of which a malfunction of the arrangement can be recognized.

  • Patent number: 10061310
    Abstract: A method for the control of an industrial truck during order picking by an industrial truck with at least one environment sensor for the detection of the relative position of an operator in the environment of the industrial truck. The method includes moving the industrial truck using a control system. As the position of the operator changes, and when the operator stops, the industrial truck is stopped at a freely selectable distance specified in advance in the longitudinal direction of the vehicle between a reference point of a load handling device of the industrial truck and the position of the operator.

  • Publication number: 20150205271
    Abstract: The method and the apparatus are concerned exclusively with dynamic processes that can be represented dominantly by discrete-event processes and for the dynamics of which it is not the time but rather the logical order of the symbols that is critical. The method and the apparatus cater to the specifics of discrete-event problems. The technical apparatus for designing and realizing automated reactions to the failure of actuators and sensors in discrete automation-engineering installations ensures that the effects of said failures on the process remain at a minimum, and also a method that allows said faults to be systematically integrated into discrete-event models in order to take this as a basis for carrying out formal design of fault-tolerant discrete-event controllers.

  • Publication number: 20150089995
    Abstract: The present disclosure relates to accelerator type crash simulation test systems. These systems provide repeatable and reliable simulation of vehicle frontal impact crash events. The crash simulation test systems are capable of simulating motion in the form of rotation about a vertical Z-axis and/or translation in a direction perpendicular to the motion of the ServoSled. The combination of these motions is generally known as yaw. Yaw motion is of particular interest in frontal crash events in which the center of impact is offset from the center of the vehicle. The yaw motion can be achieved, for example, in several embodiments by the use of off-board actuators that supply yawing motions to an onboard platform.

  • Patent number: 8943871
    Abstract: A crash sled system for simulating the deceleration and pitching motion associated with vehicle crashes. A main sled is accelerated in accordance with vehicle deceleration that occurred during a crash event. A pitching platform is located above and moves with the main sled. Forward and rear guide assemblies are provided which are located along the sides of the pitching platform when the main sled and pitching platform are in the pre-launch position. When the main sled is launched, the front and rear ends of the pitching platform travel along paths established by the guide assemblies. Prior to launch, the guide assemblies are set to angles of inclination that provide linear approximations to paths for the forward and aft ends of the pitching platform that will result in pitching motion experienced by vehicles during the crash events being simulated. Variously configured guide assemblies are disclosed that provide design trade-off between simulation accuracy and system complexity.
