PARAMETER ALLOWABLE RANGE DESCRIPTION
Full Accel Rate HS
Full_Accel_Rate_HS_SpdM
0x307F 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) at which the speed command increases when full
throttle is applied at high vehicle speeds. Larger values represent slower
response. See Figure 7 for relationship between Full Accel Rate HS, Full Accel
Rate LS, and Low Accel Rate.
Full Accel Rate LS
Full_Accel_Rate_LS_SpdM
0x3016 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) at which the speed command increases when full
throttle is applied at low vehicle speeds.
Low Accel Rate
Low_Accel_Rate_SpdM
0x3081 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) at which the speed command increases when a
small amount of throttle is applied. This rate is typically adjusted to affect low
speed maneuverability.
Neutral Decel Rate HS
Neutral_Decel_Rate_HS_SpdM
0x3018 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) that is used to slow down the vehicle when the
throttle is released to neutral at high vehicle speeds.
Neutral Decel Rate LS
Neutral_Decel_Rate_LS_SpdM
0x3070 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) that is used to slow down the vehicle when the
throttle is released to neutral at slow vehicle speeds.
Full Brake Rate HS
Full_Brake_Rate_HS_SpdM
0x301B 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) at which the vehicle slows down from high speeds
when full brake is applied or when full throttle is applied in the opposite
direction. See Figure 8 for relationship between Full Brake Rate HS, Full Brake
Rate LS, and Low Brake Rate.
Full Brake Rate LS
Full_Brake_Rate_LS_SpdM
0x3077 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) at which the vehicle slows down from low speeds
when full brake is applied or when full throttle is applied in the opposite
direction.
Low Brake Rate
Low_Brake_Rate_SpdM
0x301A 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) at which the vehicle slows down at all speeds when
a small amount of brake is applied or when a small amount of throttle is
applied in the opposite direction.
The Low Brake Rate parameter should always be set less than or equal to
the Neutral Decel Rate LS, Neutral Decel Rate HS, Full Brake Rate LS and Full
Brake Rate HS.
