  • Patent number: 11067460
    Abstract: A torque sensor mounted on a rotating element in a motor vehicle, including at least one strain gauge and emitting an electrical signal as a function of the torsion experienced by the rotating element, the torque sensor having a moving part intended to be driven in rotation with the rotating element and including the strain gauge and a fixed part including a first printed circuit board. The torque sensor also acts as an angular-position sensor, the moving part bearing angularly distributed targets passing in succession past a first annular sector borne by the first board including a secondary receiver winding generating a sine signal, a secondary receiver winding generating a cosine signal, and a primary emitter winding inducing a voltage in the receiver windings.

  • Publication number: 20200400481
    Abstract: Various embodiments include determining a level of a surface of a fluid and/or for determining a quality of the fluid in a fluid container. An example apparatus comprises a sound transducer module having two sound transducers designed to receive and emit sound signals in such a manner that a superimposition sound signal results when the sound signals are superimposed, and a reference element arranged in the fluid at a predefined distance from the sound transducer module and is designed to reflect the superimposition sound signal. The sound transducer module is designed, by superimposing the at least two sound signals, to emit the superimposition sound signal both in a first direction to the surface of the fluid and in a second direction to the reference element, said second direction running at a predetermined sound signal angle with respect to the first direction.

  • Publication number: 20180188128
    Abstract: The invention relates to a method for calibrating a torque sensor which is arranged in the drivetrain of a motor vehicle. In order to specify a method for calibrating a torque sensor which is arranged in the drivetrain of a motor vehicle, which method is less complex and therefore more cost-effective, firstly the uncalibrated torque sensor is arranged in the fully completed drivetrain in the motor vehicle and subsequently a first known value for a torque is applied to the drivetrain of the motor vehicle and then a second known value for a torque is applied to the drivetrain of the motor vehicle and the first output signal which is generated by the torque sensor is assigned to the first known value for a torque and the second output signal which is generated by the torque sensor is assigned to the second known value for a torque, the torque sensor being calibrated in the fully completed drivetrain of the motor vehicle in this way.

  • Patent number: 9909540
    Abstract: The internal combustion engine includes at least one cylinder, an exhaust gas tract having a measuring device, and a tank ventilation system having a purge air line, which provides pneumatic communication between the tank ventilation system and the cylinder. The purge air line has a sensor for ascertaining a hydrocarbon content of a gas flow from the tank ventilation system to the at least one cylinder. Fuel metering into the cylinder is controlled dependent on the ascertained hydrocarbon content. An exhaust gas characteristic of an exhaust gas flow that flows in the exhaust gas tract is detected by the measuring device and compared with a specified target value. If the ascertained difference between the detected exhaust gas characteristic and the specified target value exceeds a specified threshold, a test is carried out to determine whether the sensor has a malfunction.

  • Patent number: 9841309
    Abstract: In a method for measuring the fill level of a fluid in a housing using an ultrasound sensor, detected multiple echoes in relation to a signal are reflected from a reference point and level echoes in relation to the signal reflected from the fluid level are evaluated in relation to their fluctuation width. The level echoes can be identified in this manner and the fill level determined from the transit times of the signals to the reference point and to the fluid level.

  • Publication number: 20170184057
    Abstract: The present disclosure relates to internal combustion engines in general. Some embodiments of the teaching may include valve units for use in a fuel tank system of an internal combustion engine having a fuel tank and a storage element for temporary storage of hydrocarbons, wherein the fuel tank and the storage element are connected together such that the hydrocarbons which gasify out of a fuel in the fuel tank are stored in the storage element. They may include a purge air pump connected to the storage element and conveying fresh air to the storage element, thereby releasing the stored hydrocarbons and supplying them to a combustion chamber of the internal combustion engine and a movable adjustment element with at least two positions. The first position may connect a pressure side of the purge air pump to a first line and a suction side of the purge air pump to a second line. The second position may connect the pressure side to the second line and the suction side to the first line.
