This package is responsible for estimating acceleration using the output of ekf_localizer. It uses lowpass filter to mitigate the noise.

use_odom |
bool |
use odometry if true, else use twist input (default: true) |
accel_lowpass_gain |
double |
lowpass gain for lowpass filter in estimating acceleration (default: 0.9) |
Future work includes integrating acceleration into the EKF state.
