  • Publication number: 20170277604
    Abstract: A method of arbitrating conflicting outputs in a redundant control system. Execution data of a task executed by each controller in the redundant control system is recorded. The execution data includes an initial timestamp of each execution stream, identification of critical functions in each execution stream, and parameter values used by the critical functions. A path executed by each controller is identified based only on the critical functions executed for each execution stream. The recorded execution data of each executed path is applied to an arbitration module. An output result from one of the respective controllers selecting, by an arbitration module, based on the recorded execution data of each executed path. The output result of the selected controller is communicated to a next module for further processing.

  • Patent number: 9771055
    Abstract: A front impact mitigation system for a host vehicle and a method for operating a front impact mitigation system. The front impact mitigation system can take into account the position of a rear object that trails the host vehicle to develop a modified front impact mitigation control signal that at least partially mitigates the likelihood of certain rear impact collisions between the rear object and the host vehicle when the host vehicle is responding to the presence of an impending leading obstacle. A modified front impact mitigation control signal may be developed to account for the speed of the host vehicle and the distance that the rear object trails the host vehicle.

  • Publication number: 20170261599
    Abstract: A method and sensor system are disclosed for automatically determining object sensor position and alignment on a host vehicle. A radar sensor detects objects surrounding the host vehicle in normal operation. Static objects are identified as those objects with ground speed approximately equal to zero. Vehicle dynamics sensors provide vehicle longitudinal and lateral velocity and yaw rate data. Measurement data for the static objects—including azimuth angle, range and range rate relative to the sensor—along with the vehicle dynamics data, are used in a recursive geometric calculation which converges on actual values of the radar sensor's two-dimensional position and azimuth alignment angle on the host vehicle.

  • Publication number: 20170241062
    Abstract: The present disclosure discloses a composite balance ring and a washing machine. The balance ring is internally hollow to form a chamber. The chamber is horizontally provided with a partition plate which divides the chamber into upper and lower chambers. The upper and lower chambers communicate through an overflow structure and a backflow structure, and the chamber is filled with balancing liquid with a level close to the partition plate. During the dehydration process of the washing machine, the balancing liquid in the lower chamber overflows into the upper chamber by a low overflow speed through a narrow gap that forms the overflow structure, and the balancing liquid remaining in the lower chamber provided with a counterweight force in the inner tub, so that the increase of eccentric displacement of the inner tub due to eccentric flowing of the balancing liquid is avoided.
