This parameter requires a key cycle off-on to be effective.
M1.6-3 Accelerator Damping Factor ”AccDamp”
This setting is used to damp the acceleration demand when the accelerator is not fully pressed.
• If set to 1 (no damping), means no effect on accelerator.
• If set greater than 1 (damped), the accelerator is “damped” in the range between 0% and 75%
according to the number. This can help to avoid aggressive and oscillating response at low pedal
demand with light vehicles and high torque motors.
If it is necessary to use it, for torque mode the suggested values are between 2 and 4, while for speed
mode it is suggested to use values from 4 to 9.
The behaviour of this parameter is explained by the following figure for Torque Mode:
“M3-14 AccDamp” effect in torque mode
In other words if accelerator is pressed below 75% the torque responsiveness will be softer than if
pressed more than 75%. The responsiveness increases as much as the accelerator pedal is pressed and
approaching the 75% of the range. This damping affects both “M1.1-1 Accelerator ramp time “Acc
Ramp”” and “M1.1-2 Accelerator release ramp time “Rel Ramp”” in torque mode.
The behaviour of this parameter is explained by the following figure for Speed mode :
