    摘要: The invention relates to a system for detecting the rotational speed of a wheel or another rotating body with a sensor (1, 6), in particular, an active sensor (1), coupled with an encoder (23) by means of a magnetic field, which rotates with the rotating body, in particular, for the automotive industry. If, on the known systems, the air gap between the sensor device (S1, S2) and the encoder (23) is too small, then flipping and thus a duplication of the measured rotational speed of the wheel can happen and lead to problems in safety devices of the vehicle, which need a correct indication of the wheel rotational speed for proper operation. The aim of said invention is to improve tolerance on the fitting position of the known systems. Said aim is achieved, whereby the use of two separate signal paths (S1, f1; S2, f2) is provided, which comprise sensor devices (S1, S2) with a different sensitivity. The signal paths (S1, f1; S2, f2) are embodied, so that a signal path (S1, f1) with the highest sensitivity is always available, so that, in the normal undisturbed case, minimal optical distortions of the encoder track (13) for maximal air gaps are obtained, while simultaneously a monitoring signal path (S2, f2) is always available, the sensitivity of which is such that flipping is safely avoided in all magnetic conditions.

    摘要: The invention relates to an arrangement consisting of a wheel speed sensor (1) and a control device (ECU). The wheel speed sensor is connected to the control device by means of a data interface (k1,k2,k3,k4). Said wheel sensor comprises means for transmitting additional information in signal channels (t2...t10) and each information is associated with a signal channel and/or a fixed number of signal channels. The wheel speed sensor has switching means (10,11) enabling modification of the allocation of said additional information to available channels by means of mode switching. The additional information is transmitted in the intervals occurring between the rotational speed pulses. The number of channels is reduced when speed increases.

    摘要: For acquiring and evaluating measured variables which are critical for safety, e.g. yaw rates (GR), as input variables of a motor vehicle control system, the measured variables are obtained by means of two mutually independent measuring channels (M1, M2) of which one measuring channel (M1) acquires the entire range to be measured whilst the other measuring channel (M2) is set at a partial range. In order to detect errors, the output variables of the measuring channels (M1, M2) are checked for conformance of the measured variables acquired by the measuring channels and/or for plausibility of the measurement results.

    摘要: A sensor arrangement for the precise detection of relative movements between an encoder and a sensor A sensor arrangement for the precise detection of relative movements between an encoder and a sensor, comprising an encoder (7, 28) having an incremental scale (23, 24, 25) using multiple measurement increments (λ), and a sensor (8), which is magnetically coupled to the encoder (7, 28) via an air gap, and which comprises at least two magnetic field sensor elements (SE1, SE2), which are disposed in the direction of the relative movement around a defined distance (Δx) at an offset from each other, wherein the magnetic field sensor element output signals (V1, V2) are displaced relative to each other with respect to the detection of a measurement increment (λ) or a defined proportion of a measurement increment (N, S) around a relative velocity dependent time difference, wherein the sensor (8) has a signal processing switching circuit (40), which comprises an interface module (33) that generates a sensor output signal (Is3,Is4) comprising at least one velocity signal as a function of this time difference. The invention further relates to a method for the precise detection of relative movements between an encoder and a sensor, as well as to the use of a sensor arrangement in motor vehicles, particularly as a tire rotation detection system.

    摘要: Disclosed is an electrohydraulic pressure regulating device (30) with integrated pressure sensors (16) for detecting the pressure of a fluid in pressure lines (34), wherein several pressure measuring transducers are arranged in a cavity (10), each measuring transducer consisting of a pressure measuring membrane (32) and an electrically passive measuring transducer (33). The measuring transducer does not include a device for calibrating the electric transducer signal. The invention also relates to a method for compensating errors, wherein error-corrected pressure characteristic variables are calculated from the pressure characteristic variables of the pressure sensors by means of a digital allocation specification.
