  • Publication number: 20050038588
    Abstract: A method of controlling the wheel speed of a vehicle wheel supported by a surface to achieve a desired vehicle acceleration, desired yaw rate or a desired vehicle velocity. The method receives sensor readings indicative of a vehicle state and operator input. From the received sensor readings a current wheel speed and a desired wheel speed are determined. A torque is applied to the wheel to correct for any wheel speed error, the difference between the desired wheel speed and the current wheel speed. To determine the amount of torque that may be applied to the vehicle wheel while preventing the wheel from slipping, a friction coefficient between the wheel and the surface may be determined.

  • Publication number: 20050038589
    Abstract: A method and a system for estimating a friction coefficient between a driven wheel and a surface. The method uses a Fourier series to calculate the friction coefficient. More specifically, a desired wheel slip ratio is calculated using received sensor readings related to a system state and a desired wheel speed determined from various system conditions or user inputs. A Fourier series is used to estimate the friction coefficient. The method is generally cycled many times each second to allow for varying road conditions by adjusting the Fourier series coefficients after each cycle. The system generally includes a wheel speed sensor and an accelerometer providing signals to a processor or various modules to perform the above method.
