Abstract: A method of communicating a notification includes identifying an issue associated with a target vehicle. A location of the target vehicle is determined, and a notification signal is broadcast from a host vehicle. The notification signal includes the location of the target vehicle and the identified issue associated with the target vehicle. The broadcast notification signal is received by the target vehicle, which determines that the received notification signal is intended for the target vehicle, by comparing a current location of the target vehicle to the location of the target vehicle included in the notification signal. When the target vehicle determines that the broadcast notification signal received from the host vehicle is intended for the target vehicle, the target vehicle may issue an alert signal to alert an occupant of the target vehicle of the issue associated with the target vehicle.

Abstract: Methods and systems are provided for suppression of steering wheel vibrations generated by periodic disturbances in a vehicle steering system. An exemplary method reducing steering wheel vibrations caused by periodic disturbances involves determining a gross torque attributable to the periodic disturbances in the steering system, identifying a desired amount of suppression of the vibrations at the steering wheel, determining an offset torque based on the gross torque and the desired amount of suppression, and generating a motor command signal in a manner that is influenced by the offset torque. The motor drive command signal is provided to an electric motor coupled the steering wheel and/or the vehicle tires, and the motor drive command signal influences the torque applied by the motor to assist steering of the vehicle tires by the steering wheel in a manner that attenuates the vibrations communicated to the steering wheel by the desired amount.

Abstract: Methods and apparatus are provided for reducing steering wheel vibrations in electronic power steering systems. The apparatus includes a processor and performs a method that estimates an average angular wheel speed of at least one wheel of the vehicle; determines an average wheel angle from the average angular wheel speed; generates sine and cosine functions of the average angular wheel angle; processes the sine and cosine functions with a steering wheel torque signal received from a torque sensor to extract amplitude components of at least one of the sine and cosine functions; reconstructs the sine and cosine functions using the steering wheel torque signal; combines the sine and cosine functions to provide a control signal, and controls the EPS system via the control signal to attenuate smooth road shake vibrations in a steering wheel of the vehicle.
