Abstract
Systems and methods for smoothing accelerator signal oscillations caused by road interference are provided. The disclosed systems and methods may apply a pedal smoothing logic/filter to avoid unnecessary torque request oscillation (e.g., torque hunting) caused by pedal oscillation. For example, a control may determine when outside road inputs are causing the driver to oscillate the pedal. When road interference is occurring, the pedal smoothing logic/filter is activated to limit torque request oscillation. When road interference is minimal or non-existent, the pedal smoothing logic/filter is deactivated to maintain vehicle responsiveness for intended driver inputs. A method may include determining a shock value based on a vehicle acceleration, comparing the shock value to a threshold value, and activating a pedal smoothing logic to smooth an accelerator signal based on the shock value being greater than the threshold value. A system may be configured to perform the disclosed method(s).
