- L15 | self.lane_width_estimate = 3.7
- L15 | self.lane_width_estimate = 3.5
- L17 | self.lane_width = 3.7
- L17 | self.lane_width = 3.5
- L38 | speed_lane_width = interp(v_ego, [0., 31.], [3., 3.8])
- L38 | speed_lane_width = interp(v_ego, [0., 31.], [3., 3.5])
Go to the openpilot/blob/devel/selfdrive/controls/lib/latcontrols_helpers.py
