Randy Mackay 7e2214c2be Rover: simplify logic for lateral-accel override during use-pivot-steering
It was theoretically possible that the lateral-acceleration would not be overwritten if the yaw-error-cd was exactly zero

khancyr 2b0645d6a1 Rover: get_throttle_out calls do not require skid-steering arg 2017-11-08 15:45:43 +09:00
Daniel Widmann bc7cf97b4e Rover: don't use GPS speed to detect reversing
instead pass reverse to attitude controller based on desired speed
2017-11-08 14:37:59 +09:00
Randy Mackay ea70755f00 Rover: fix speed nudge
fix bug when target speed was exactly zero which caused nudge to be a large negative value

khancyr 2ceb29e9da Rover: use abs for int within calc_speed_nudge
same issue resoled for log-write-nav-tuning

khancyr 58b643c458 Rover: replace divide with multiply in calc_throttle
non functional change
2017-08-17 09:45:21 +09:00
Randy Mackay c9927e6af6 Rover: bug fix to steering mode top speed
Also non-functional change to calc_throttle to make call to calc_speed_nudge consistent

Randy Mackay 167a856cdb Rover: remove THR_MIN, THR_MAX parameters from vehicle
enforcing these limits is now handled by AP_MotorsUGV class

Randy Mackay 95c5ada3e9 Rover: modes use stop_vehicle to stop gently
modes slow to a stop instead of immediately setting motors to zero
vehicle centers steering when stopping

Randy Mackay 0b917cfd36 Rover: mode auto guided and rtl slow before destination
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.

Randy Mackay d99108f3bc Rover: use AR_AttitudeControl for throttle control
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

Randy Mackay a00c7e0acb Rover: mode calc_reduced_speed_for_turn gets some const for local variables 2017-08-12 12:29:13 +09:00
khancyr 848df551ac Rover: formatting and comment fixes to mode class 2017-08-05 17:02:52 +09:00
Randy Mackay 4f5e82f406 Rover: mode fixes for reversing 2017-08-05 11:20:58 +09:00
Randy Mackay 2accb5831d Rover: mode refactoring
add ahrs reference
add set-desired-location method
move _reached_destination member in from child
calc_lateral_acceleration args renamed and added comemnts
calc_lateral_acceleration updates _yaw_error_cd
remove calc_lateral_acceleration method with no arguments
calc_throttle updates _speed_error and becomes protected
remove unused variables from calc_throttle
calc_reduced_speed_for_turn_or_distance reworked
do not use rover throttle or rtl_complete
calc_nav_steer comment updates
remove unused update_navigation
