  • Patent number: 10585772
    Abstract: A power supply diagnostic strategy for discrete power supply diagnostic states is independent of the underlying memory structure. The values used in the associated algorithm are selected to ensure that random linked failures will be detected. This applies to planar memory structures with 1, 2, 4, 6, 8, 12, and 16 common lattices, or physical memory structures with individual bit dispersed memories with 1, 2, 4, 6, 8, 12, and 16 consecutive bit splices. Further, the strategy provides that the various monitored voltage tables remains distinct even with compiler optimization activated.

  • Patent number: 10577016
    Abstract: An electric power steering system includes a control for providing a calculated torque assist demand in the event of failure of a steering wheel torque sensor. The control is responsive to one or more of a vehicle speed, a steering column position, a steering column velocity, a gear lever position, a vehicle yaw rate and a vehicle lateral acceleration for generating the calculated torque assist demand. The control is operable to modify the torque assist demand by providing one or more of (a) friction and inertial compensation, (b) vehicle oversteer compensation, (c) reverse motion compensation, (d) damping compensation and (e) self steer prevention.

  • Patent number: 10550861
    Abstract: A steering gear includes a housing defining a chamber. A piston divides the chamber into first and second chamber portions. The piston is moveable along a linear axis relative to the housing upon pressurization of fluid in one of the first and second chamber portions. A pressure relief vents pressurized fluid from one of the first and second chamber portions to one other of the first and second chamber portions upon movement of the piston to a predetermined position. The pressure relief assembly includes a first valve at a first end of the pressure relief assembly and a second valve at a second end of the pressure relief assembly. The pressure relief assembly is axially movable relative to the piston to adjust the position of the first valve and the second valve relative to the piston.

  • Patent number: 10493986
    Abstract: A vehicle driver assist system includes an expert evaluation system to fuse information acquired from various data sources. The data sources can correspond to conditions associated with the vehicle as a unit as well as external elements. The expert evaluation system monitors and evaluates the information from the data sources according to a set of rules by converting each data value into a metric value, determining a weight for each metric, assigning the determined weight to the metric, and generating a weighted metric corresponding to each data value. The expert evaluation system compares each weighted metric (or a linear combination of metrics) against one or more thresholds. The results from the comparison provide an estimation of a likelihood of one or more traffic features occurring.
