Topic: Reversing for Multi-Trailer vehicles
Answer:
There are different strategies that can be followed to create smooth reverse maneuvers; the effectiveness of these strategies varies depending on the design scenario and the space availability (smoother envelopes typically require more space):
In general, smooth reverse maneuvers can be achieved by:
- Minimizing the amount of steering from the first part. Finish the forward maneuver with the cab and wheels pointing in the direction the trailer needs to travel in reverse to reach the desired end position.
- Reducing the number of sections (clicks) to get the vehicle into the desired position (e.g., a parking stall).
- Changing the steering gradually, i.e., only a few degrees, while the vehicle moves backward several feet or meters.
- Avoid switching the trailer's travel direction. If the vehicle and trailer are aligned with the desired end position, the Force Straight Line tool can help minimize sections and steering changes for one- and two-part vehicles. This option can be enabled in the setting shown below.
- Steering from the first part in two-part vehicles can provide additional control over the inswings and outswings of the front part, making the envelopes smoother. This option can be enabled in the setting shown below.
