FINE TUNING
Seven additional vehicle performance characteristics can be adjusted:
6 Response to Increased Throttle
7 Response to Full Throttle Release (Compression Braking)
8 Transitioning from Flat Ground to Downhill
9 Hill Climbing
bk WalkAway ™ Braking
bl Low-Speed Field Braking
bm Applying the EM Brake.
These characteristics are related to the “feel” of the vehicle and will be different
for various applications. Once the fine tuning has been accomplished, it should
not have to be repeated on every vehicle.
6 Response to Increased Throttle
The vehicle’s response to throttle increases can be modified using the ACCEL ,
THROTTLE MAP , and FIELD MAX parameters. Optimal vehicle response is tuned by
adjusting these parameters and then accelerating the vehicle from a dead stop
under various throttle transition conditions.
step 1. Set THROTTLE MAP as desired. In most applications a setting below
50% is used to provide greater control for low-speed maneuver-
ing.
step 2. Select Mode 1. While driving the vehicle, adjust M1 ACCEL for
the best overall acceleration response. If the vehicle starts too
slowly under all driving conditions,
M1 ACCEL should be reduced.
(Remember, the accel rate parameter is in units of time.)
step 3. Increasing vehicle acceleration. If acceleration feels good for slow
or moderate throttle transitions but the vehicle initially starts
too slowly, set
FIELD MAX higher. If acceleration is not satisfactory
when the throttle is transitioned quickly from zero to full speed,
decrease
M1 ACCEL to obtain the desired fast throttle response.
step 4. Achieving better control at low speeds. If the vehicle responds well
for fast, full range throttle transitions but is too jumpy during
low speed maneuvering, reduce the
THROTTLE MAP .
step 5. Select Mode 2 and repeat the procedure.
You may wish to dedicate one of the two modes for precision maneuvering.
The
ACCEL , MAX SPEED , and MAIN C/L parameters can be tuned exclusively for this
precision-maneuvering mode to obtain comfortable vehicle response. Because
THROTTLE MAP and FIELD MAX are not mode-specific, you may need to re-tune Mode 1
if you make adjustments to these two parameters when tuning Mode 2.
