摘要： A multi-pole annular encoder having 2N poles distributed irregularly is positioned facing a sensor that detects transitions between the poles. Times corresponding to the detected transitions are stored and the times that have elapsed between each transition and the previous transition of order 2N, which constitute durations for a complete revolution of a rotating member, are calculated. When the durations thus calculated are stable, a time that has elapsed between a tested transition and the previous transition is calculated, and a characteristic angle of the tested transition is deduced therefrom, this being proportional to a ratio between a time that has elapsed since the previous transition and a stabilized duration for a complete revolution. An index transition is identified and is used to ascertain absolute position of the encoder with respect to the sensor.

摘要： A method includes writing vehicle data parameters (VDPs) into a memory in order of a vehicle outputting the VDPs. The method also includes displaying a first view of a graphical user interface (GUI) on a display. The GUI includes one or more VDP graphs, a graph-axis control, and a first vehicle operating condition (VOC) indicator at the graph-axis control. The method also includes displaying a second view of the GUI on the display in response to a selection of the first VOC indicator. The first and second views include first and second sets of VDP graphs, respectively. The second set of VDP graphs includes VDPs not represented in the first set of VDP graphs. Graph-axis control segments within the graph-axis control in the first and second views cover different portions of the graph-axis control. The graph-axis control segments correspond to different portions of the VDPs written into the memory.

摘要： A sensor detects the rotation of a component (object) of a vehicle in a non-contact manner, and generates a differential signal according to the rotation. Two comparators have different hysteresis characteristics. At both edges of one signal that is an output of one of the comparators, if a signal of the other comparator is not at the same level, it is determined that a distance (gap) between an object and the sensor is within a predetermined range in which the differential signal is effective.

摘要： A variable-reluctance magnetic detection head delivers an electrical signal (Uin) and a rising wavefront of the electrical signal is compared with a first threshold (Th) in order to switch from a first state (B0) to a second state (B1), and a falling wavefront is compared with a second threshold (Tb) lower than the first threshold (Th) in order to switch from the second state (B1) to the first state (B0). In a diagnostics step, the first threshold (Th) or the second threshold (Tb) is modified, bringing these thresholds closer together, and a magnetic detection head is diagnosed as being defective if the duty cycle of the second state (B1) is modified during the diagnostics step by a value higher than a diagnostics threshold predetermined in relation to a reference level.

摘要： A linear position measuring system and a method for determining an absolute position of a carriage along a slide rail are disclosed. An analog signal progression (S) based at on at least one reference point is here discretely scanned in response to a first threshold (SW1) and second threshold (SW2). The resultant digital values are stored in a first measured value register (MR1) and a second measured value register (MR2). The contents of the first and second measured value register (MR1, MR2) are compared with the respective contents of a first and second set measured value register. The reference point is output as an ideal reference point if the differential value lies within a predetermined tolerance range, and is otherwise discarded.
