  • Patent number: 10337576
    Abstract: A brake pad wear measuring system for measuring brake pad wear for a vehicle disc brake system includes a first coil excitable to create a first magnetic field, and a first target associated with the first coil. The first coil and the first target are configured for movement relative to each other in response to application of the disc brake system. The relative movement causes the first target to move within the first magnetic field and affect the inductance of the first coil. The brake pad wear measuring system also includes a second coil excitable to create a second magnetic field, and a second target associated with the second coil. The second coil and the second target are configured for movement relative to each other in response to application of the disc brake system. The relative movement causes the second target to move within the second magnetic field and affect the inductance of the second coil.

  • Patent number: 10330542
    Abstract: A torque sensor assembly for use in a vehicle power steering system has magnets, coaxial first, second, and third flux closure members around the magnets, and first and second magnetic sensors. Each of the plurality of magnets emits a magnetic field. The second flux closure member is between the first and third flux closure members. The first and third flux closure members collect the magnetic fields having a first polarity. The second flux closure member collects the magnetic fields having a second polarity that is opposite the first polarity. The first and second magnetic sensors are positioned to have like polarity. The first sensor is between the first and second flux closure members. The second sensor is between the second and third flux closure members. A torque signal is calculated by subtracting a second signal generated by the second sensor from a first signal generated by the first sensor.

  • Publication number: 20190182467
    Abstract: A method of determining the characteristics of a scene around a vehicle comprises capturing a stereo pair of images of the scene and processing the images to produce a depth map of the scene. Each pixel in the depth map is assigned a value that corresponds to the range of a corresponding region in the scene, the pixels being arranged in a grid of rows and columns with each column of pixels in the grid corresponding to a vertically oriented set of regions in the scene and each row a horizontally oriented set of regions in the scene. The values for one or more columns of pixels in the depth map are binned to form a corresponding histogram, each bin in the histogram having a count value that corresponds to the number of pixels in the column that have a depth within the range assigned to the bin.

  • Patent number: 10315650
    Abstract: A control system and corresponding control method which is adapted and intended for use in an own vehicle for detecting one or more objects based on environmental data obtained from one or more environmental sensors disposed at the vehicle. The environmental sensors are adapted to provide an electronic control unit of the control system with the environmental data which reflect the areas in front of, laterally next to and/or behind the vehicle. The control system is at least adapted and intended for detecting at least one object by means of the environmental sensors during a predetermined period of time or continuously. A movement of each detected object is determined. The presence of a rotational part in the movement of at least one object is identified, and when a rotational part is present, a probability of an occurrence of a collision between the corresponding object and the own vehicle is calculated.
