US 12,384,394 B2 · Pedal smoothing systems and methods

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).

Dependent claims

A method comprising:

scanning a travel path of a vehicle using a forward-looking camera;
analyzing image data of the forward-looking camera to detect a rough road condition;
determining a shock value based on a vehicle acceleration;
comparing the shock value to a first threshold value;
and
in response to detection of the rough road condition using the image data and the shock value being greater than the first threshold value, activating a pedal smoothing logic to smooth an accelerator signal.
