Method and system for drivetrain oscillation detection and control for anti-lock brake systems |
摘要 |
A method and system for modifying anti-lock brake control to a vehicle experiencing drivetrain-induced oscillations. A wheel speed of each of the wheels is sensed to generate a corresponding speed signal. A drivetrain-induced oscillation condition is detected in one of two ways. First, a wheel speed peak count is determined for each of the wheels. A drivetrain-induced oscillation is then detected if multiple peaks occur within a predetermined period of time. Alternatively, a frequency of oscillation for each of the wheel speeds is determined and compared to a predetermined frequency threshold. Upon determining that the vehicle is experiencing drivetrain-induced oscillation during an ABS event, brake pressure is applied to the driven wheels at approximately the same frequency as the frequency of oscillation of the drivetrain-induced oscillation.
