摘要： A position sensor is configured to use a Wiegand wire, position magnet(s) and a reset magnet in which changes in polarization of the Wiegand wire caused by the position magnet(s) can be reset by the reset magnet. The position magnet(s), which can move in relation to the Wiegand wire, can have relatively stronger magnetic flux densities, and the reset magnet, which can be fixed in relation to the Wiegand wire, can have a relatively weaker magnetic flux density. When the position magnet(s) are proximal the Wiegand wire, the relatively stronger position magnet(s) overcome the reset magnet to cause a change in polarization of the Wiegand wire which produces an electrical pulse which can be counted. However, when the position magnet(s) become distal to the Wiegand wire, the relatively weaker reset magnet can reset the polarization of the Wiegand wire to prepare for a next count. As a result, the total number of magnets required in the system can be reduced, and the probability of failing to reset the Wiegand wire can be lowered.

摘要： A pole wheel is provided. The pole wheel can be mounted on a brake disk of a vehicle wheel brake. The pole wheel has apertures which are uniformly distributed over its circumference and which are spaced apart from one another by radial webs. The pole wheel has an axially protruding bulge radially above its apertures and radial webs.

摘要： A detection device is for detecting a passage timing of a turbine blade. This detection device is provided with: a sensor including a magnet and a coil that is disposed at a position subject to magnetic flux generated by the magnet and is configured to detect an induced electromotive force based on a change in the magnetic flux accompanying passage of the turbine blade; and an analyzer configured to detect the passage timing of the turbine blade, on the basis of an integrated signal obtained by integrating a signal based on the induced electromotive force.

摘要： A vehicle control system includes a powertrain electronic control unit and an electronic stability control unit that is connected to the powertrain electronic control unit via a vehicle communication bus. The vehicle powertrain includes a wheel, a wheel speed sensor that is configured to detect a speed of the wheel, an electric motor that is configured to drive the wheel, and an electric motor speed sensor that is configured to detect the speed of the electric motor. If the vehicle is not traveling at low speeds (for example, less than 2 kilometers per hour), the electronic stability control unit controls the vehicle based on an output of the wheel speed sensor. However, if the vehicle is traveling at low speeds, the electronic stability control unit controls the vehicle based on an output of the electric motor speed sensor.

摘要： A sensor assembly includes a sensor element and at least two control units, each having an evaluation and control unit and an energy source. In a first control unit, a first evaluation and control unit is connected to a first energy source, and in a second control unit, a second evaluation and control unit is connected to a second energy source. The at least two control units and the sensor element are interconnected by at least one separate interconnection unit. Each interconnection unit connects a first connection of an associated sensor element to the first energy source and/or to the second energy source. A second connection of the sensor element is earthed. A sensor current flowing through the sensor element is modulated at least with information about a detected measured variable. The first evaluation and control unit and/or the second evaluation and control unit evaluate(s) the detected sensor current.

摘要： A wheel speed estimation device is to be applied to a four-wheel drive vehicle including a first coupling device for a rear left-wheel axle and a second coupling device for a rear right-wheel axle. These coupling devices respectively change states of engagement of a left engagement state and a right engagement state to the any one of a completely restraint state, a release state, and an incompletely restraint state. The wheel speed estimation device includes a correction parameter calculator that calculates correction parameters affected by a difference in wheel radius between wheels based on all wheel rotation speed signals, and a wheel speed calculator that calculates wheel speeds based on the wheel rotation speed signals and the correction parameters. Further, the correction parameter calculator stops calculation of the correction parameters when at least one of the left engagement state or the right engagement state is the incompletely restraint state.

The first bridge circuit is configured to generate a first differential signal based on sensor signals generated by the plurality of magnetic field sensor elements. The plurality of magnetic field sensor elements include a first, second, and third pair of sensor elements. The first pair are arranged at center region of the magnetic sensor, the second pair are arranged at a first side region of the magnetic sensor and are displaced a first distance from the first pair, and the third pair are arranged at a second side region of the magnetic sensor, opposite to the first side region, and are displaced a second distance from the first pair that is substantially equal to the first distance.
