The planning trajectory always deviations to the routing center line's left, not move along the routing line.

Currently, In my apollo system, the vehicle's path always deviations to the routing center line's left, so the vehicles move along the area between the map's left and routing centerline, not move along the center of the map.

So How to make the vehicle move along the routing line? modify some conf parameter or modify some code?

If I recall it correctly, there is one configuration parameter that controls how fast the planned trajectory converges to the route.

Which parameter that can control this? and how to tune this parameter?
