previously the user would use the LOITER_UNLIMITED or LOITER_TIME mission commands to specify that the vehicle should remain active at the destination. This was cumbersome and not the best way to specify this behaviour because these two commands are valid for regular rovers that should not try to remain active at the destination.
This separates the default/maximum speed used in Auto, Guided, RTL and SmartRTL from the CRUISE_SPEED which is used as the base for the speed-to-throttle controller (along with CRUISE_THROTTLE)
new mode class member _desired_speed_final holds target speed at destination
main vehicle code passes heading to next waypoint into auto mode.
we do not provide heading when delaying at waypoint which signals we wish
auto-mode calculates final speed at destination which allows vehicle to
make turn within value of WP_OVERSHOOT parameter assuming vehicle turns at
maximum lateral acceleration.
also direct throttle nudge replaced with speed nudge
calc_speed_max estimates vehicle's top speed based on cruise-speed and
cruise-throttle
steering mode now provides total target speed instead of using speed plug
throttle nudge
motor limits provided to attitude control to stop i-term buildup
uses negative desired speed instead of reversed flag
reporting to GCS uses new throttle controller
braking is simply enabled and allows a reverse motor output regardless of vehicle
speed
updating mission is handled by the vehicle code
slows down for turns
add active at destination
remove setting of loiter start time
removes unused calc_nav_steer
