摘要： The system and method described herein can be used to reduce the effects of periodic vibrations in an electric power steering (EPS) system for a vehicle, particularly, those that can lead to smooth road shake (SRS), torsional nibble, and/or other undesirable conditions. According to an exemplary embodiment, an electric motor is used to purposely generate counter-acting vibrations in the EPS system to cancel out the periodic vibrations generated by the wheel assemblies or corners.

摘要： A method for measuring low amplitude dynamic properties of a steering column includes mounting the steering column into a test fixture and performing test runs. The test runs include subjecting the input end of the steering column to input excitations and measuring output conditions, which include at least one of acceleration, velocity and position, and determining whether the output conditions are within a predetermined output range. Input excitations may include sinusoidal excitations having a selected frequency range, torque, or displacement; or dither excitations. The selected torque or displacement is determined using open loop calculations from the output conditions, to achieve target acceleration levels. Data is interpreted to determine the natural frequency or rim gain of the steering column, which are compared to predetermined permissible ranges. The maximum steering wheel rim gain permissible level may be equal to approximately 1 divided by the polar moment of inertia of the wheel.

摘要： The ability of a damper to attenuate smooth road shake in a vehicle is tested using a test fixture that is controlled by inputting data for periodic low amplitude periodic excitations having a selected frequency range, selected amplitude range and a selected dither representative of vehicle operation on relatively smooth roads. The selected frequency range is about 5 Hz to 30 Hz and the selected amplitude range is about 0.05 mm to 2.00 mm. A preferred frequency is about 15 Hz which is applied preferably for about 200 cycles in a series of separate tests at individual amplitudes of, for example, 0.05, 0.10, 0.15, 0.20, 0.25, 0.50, 1.00 and 2.00 mm. The damper is tested to produce low amplitude test results comprising displacement, force and velocity parameters, measured as functions of time.

摘要： Methods, system and apparatus are provided for reducing steering wheel vibrations (SWVs). At least one heterodyning operation is performed during the generation of a gain-and-phase-compensated motor drive command signal. The gain-and-phase-compensated motor drive command signal is generated at a particular angular frequency, based on an angular velocity and an angular position of a wheel. The gain-and-phase-compensated motor drive command signal is communicated to an electric power steering system to control motor torque to reduce periodic content in a periodic electrical torque signal at the particular angular frequency.

摘要： Methods and systems are provided for controlling steering in a vehicle having an electric power steering system (EPS) with a steering wheel, the EPS configured to attenuate smooth road shake (SRS) for the vehicle. A first relationship is determined between a torque of the steering wheel and motions of the steering wheel while free of SRS excitation. A second relationship is determined between the torque and the motions with SRS excitation. A mapping is generated based on the first relationship and the second relationship via a processor for use in adjusting steering control.

摘要： A raw runout signal of a tire is bandpass filtered utilizing appropriate, empirically determined, low and high tire order corners to determine the bandpass of the bandpass filter. A band-limited runout signal is then obtained and is examined for characteristic signal patterns of local runout which are known to exhibit periodically modulated cabin interior sound during vehicle movement, usually driving conditions involving highway speeds and smooth roads, which is audibly detectable by passengers based upon, for example, empirical analysis wherein the maximum gain of the bandpass filter is, preferably, unity.
