  • Integrated wheel speed and brake pad wear monitoring system
    Patent number: 10550905
    Abstract: An integrated monitoring system for a vehicle including a brake pad wear sensor and a wheel speed sensor. A wheel speed sensor signal line is connected between the wheel speed sensor and an electronic control unit. A wheel speed power line is connected between the wheel speed sensor, the brake pad wear sensor, and the electronic control unit. The electronic control unit is configured to monitor the wheel speed sensor signal line for a signal indicative of a wheel speed and monitors the wheel speed power line for a signal indicative of a brake pad condition.

  • Wheel speed sensor
    Patent number: 10488427
    Abstract: A wheel speed sensor includes an electromagnetic sensor having an electromagnetic sensor head disposed at a distal end thereof and a flange acting as a sensor support. The electromagnetic sensor head includes a magnet and an integrated circuit for sensing movement of a tone ring formed of magnetic attractive material. A sensor interface disposed at the distal end of the electromagnetic sensor is mechanically secured to a flange interface of the flange. The sensor interface can include outwardly projecting opposing tabs on opposing sides of the electromagnetic sensor head that are received by opposing apertures in parallel, spaced projecting arms that form the flange interface. In another arrangement, the sensor is inserted into an opening defined in the flange, and a retainer element is inserted into a slot formed on the electromagnetic sensor head such that the sensor cannot be extracted from the opening.
