    摘要： A method of isolating a fault in an electric power steering system includes calculating a value for fault signature components. Each of the calculated values of the fault signature components is compared to a respective threshold value, to determine if any of the calculated values of the fault signature components exceeds its respective threshold value. When at least one of the calculated values of the plurality of fault signature components exceeds its respective threshold value, the above threshold comparison results are compared to a fault table that relates pre-calculated threshold comparison results to pre-identified faults, to determine if the above threshold comparison results correspond to a pre-identified fault. Based on the fault table comparison results, a control action is automatically executed to indicate a pre-identified fault or an unknown fault in the electric power steering system.

    摘要： Methods and systems are disclosed for participative sensing of road friction conditions by vehicles, collection of the friction data from a large number of vehicles by a central server, processing the data to classify friction conditions by roadway and locale, and sending notifications of the friction conditions to vehicles as appropriate. A large number of vehicles use participative sensing systems to identify road friction estimates which are reported to the central server—where the vehicles use sensor data and vehicle dynamic conditions to estimate friction. The central server stores and aggregates the friction data, filters it and ages it. Vehicles requesting advisories from the central server will receive notices of road friction conditions which may be significant based on their location and heading. Driver warnings can be issued for low friction conditions ahead, and automated vehicle systems may also respond to the notices.

    摘要： A vehicle includes a brake system configured to resist vehicle movement. The vehicle also includes at least one controller in communication with the brake system. The controller is programmed to detect an initiation of a braking event and monitor raw signal data associated with the brake system during the braking event. The controller is also programmed to generate a feature data set based on the raw signal data that is indicative of performance of at least one component of the brake system. The controller is further programmed to identify a vehicle maneuver class based on a rate of change of vehicle movement, store the feature data set and the identified vehicle maneuver class as a data vector, and transmit the data vector to a processor.

    摘要： A method for monitoring an engine starting system includes detecting a first engine crank command, monitoring engine speed states, and collecting the engine speed states in a first buffer disposed in a first controller. A second engine crank command is determined based upon monitored electric power states from a battery. The electric power states from the battery are collected in a second buffer disposed in a second controller. The engine speed states collected in the first buffer are synchronized with the electric power states from the battery collected in the second buffer based upon the first engine crank command and the second engine crank command. A starter resistance is determined based upon the electric power states from the battery. A telematics device communicates the starter resistance and the monitored engine speed states synchronized with the monitored electric power states to a remote system.

    摘要： A system and method for converting a vehicle steering angle command to a vehicle steering torque command for a vehicle steering system in a vehicle. The method estimates a self-aligning torque that defines the torque that maintains a vehicle steering wheel at a neutral steering position or to a position that makes no slip angle at the road wheel, applies known total steering torque commands to the steering system at a plurality of sample time steps where the known steering torque commands include the self-aligning torque, and measures a vehicle steering angle at each time step. The method then models the steering system of the vehicle using the torque commands, the measured steering angles, a system delay and a plurality of unknown parameters.
