Speed Turn Parameter TuningΒΆ

The speed-scaling parameters are used to set the percentage reduction in throttle when turning around a waypoint and the distance before a target when the Rover will start to slow down.

The two parameters are listed below:

    • Range 0-100 Units: percent Increment 1 (50)
    • The percentage to reduce the throttle while turning. If this is 100% then the target speed is not reduced while turning. If this is 50% then the target speed is reduced in proportion to the turn rate, with a reduction of 50% when the steering is maximally deflected.
    • Range 0-100 Units: meters Increment .1 (50)
    • The distance to the next turn at which the rover reduces its target speed by the SPEED_TURN_GAIN. |

The parameters are set in the Mission Planner CONFIG/TUNING | Basic Tuning page:

All parameters may be adjusted in the “Advanced Parameter List” in Mission Planner). All the Rover user settable parameters are listed in APMrover2 Parameters.
