Abstract: A spindle assembly includes a power source interface configured to be operably coupled to a power bus and power the spindle assembly via the power bus, a spindle controller comprising processing circuitry, a diagnostic switch assembly operably coupled to the spindle controller and operably coupled to a logic supply bus, and a working apparatus comprising a motor and a spindle operably coupled to the spindle controller. The working apparatus may be controllable by the spindle controller to act upon a work piece to perform a work task. The processing circuitry of the spindle controller may be configured to receive a fault localization instruction from a bus control device operably coupled to the logic supply bus, and control the diagnostic switch assembly to determine a presence and a location of a fault on the logic supply bus.

Abstract: In a method for operating a vehicle (1) having a plurality of wheels (3) and wheel sensors (5) which are associated with said wheels and whose measurement signals are representative of angular speeds of the respective wheels (3), respective scaling values (SV1, SV2, SH1, SH2) are adapted when a predefined condition is met, the condition depending on the yaw rate (GR) of the vehicle and/or on the steering angle (LW) of the front/rear wheels.

Abstract: A wheel rotation speed (RD) is determined from at least two wheels of a vehicle, respectively. A variable variability measure (VAR) is determined for each wheel rotation speed (RD), respectively. The current reliability of the respective wheel rotation speed (RD) is determined as a function of the variability measure (VAR). The current longitudinal vehicle speed is determined either as a function of the wheel rotation speeds (RD) which are currently detected as being reliable, or the current longitudinal vehicle speed is determined as an extrapolation as a function of wheel rotation speeds (RD) which were previously detected as being reliable if all wheel rotation speeds (RD) are currently detected as being unreliable.

Abstract: In a method and an arrangement for the determination of an updated wheel circumference (U*) of at least one wheel (R) arranged on a vehicle, during which at least one wheel circumference (U) is assigned to at least one wheel (R) in a control unit (CU), and during which the wheel speed (RaV) is determined by means of the control unit (CU) according to the speed of rotation (RoV) of the at least one wheel (R) and according to the assigned wheel circumference (U), advantageously, a reference speed (RefV) of the vehicle and/or the wheel (R) is determined which is independent of the determined wheel speed (RaV). The discrepancy (V) between the at least one wheel speed (RaV) and the reference speed (RefV) is detected and the updated wheel circumference (U*) of the at least one wheel (R) is determined according to the discrepancy (V).

Abstract: A torque-transmitting system such as continuously variable transmission for motor vehicle has an input device and an output device whose operating state can be described in terms of characteristic operating values. The input device and the output device are adjustable in relation to each other by adjusting a ratio between characteristic operating values, which has the result of changing the transmission ratio. An actuator device performs the functions of shifting the positions of the input and output device as well as holding the devices at a set position. A control device controls the actuator device through a control signal. A computing device performs calculations as well as learning and adapting processes involved in setting the value of the control signal.
