PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Full Accel Rate HS
Full_Accel_Rate_HS_SpdM
0x381D 0x00
0.1 – 30.0 s
100 – 30000
5.0 sec Sets the rate (in seconds/Typical Max Speed) at which the speed
command increases when applying full throttle at high vehicle
speeds. Larger values represent slower response.
See Figure 16 for the relationship between Full Accel Rate HS,
Full Accel Rate LS, and Low Accel Rate.
Full Accel Rate LS
Full_Accel_Rate_LS_SpdM
0x381E 0x00
0.1 – 30.0 s
100 – 30000
2.5 sec Sets the rate (in seconds/Typical Max Speed) at which the
speed command increases when applying full throttle at low
vehicle speeds.
See Figure 16 for the relationship between Full Accel Rate HS,
Full Accel Rate LS, and Low Accel Rate.
Low Accel Rate
Low_Accel_Rate_SpdM
0x3834 0x00
0.1 – 30.0 s
100 – 30000
10.0 sec Sets the rate (in seconds/Typical Max Speed) at which the speed
command increases when a small amount of throttle is applied.
Adjusting this rate affects the low speed maneuverability.
Neutral Decel Rate HS
Neutral_Decel_Rate_HS_SpdM
0x383C 0x00
0.1 – 30.0 s
100 – 30000
10.0 sec Sets the rate (in seconds/Typical Max Speed) used to slow
down the vehicle when releasing the throttle to neutral at high
vehicle speeds.
Neutral Decel Rate LS
Neutral_Decel_Rate_LS_SpdM
0x383D 0x00
0.1 – 30.0 s
100 – 30000
20.0 sec Sets the rate (in seconds/Typical Max Speed) used to slow
down the vehicle when releasing the throttle to neutral at slow
vehicle speeds.
Partial Decel Rate
Partial_Decel_Rate_SpdM
0x3843 0x00
0.1 – 30.0 s 30.0 sec Sets the rate (in seconds) to slow down the vehicle when the
throttle (command) is reduced without being released to neutral.
Larger values represent slower response.
See Figures 16 and 17 for the relationship between Full Brake
Rate HS, Full Brake Rate LS, and Low Brake Rate.
Full Brake Rate HS
Full_Brake_Rate_HS_SpdM
0x381F 0x00
0.1 – 30.0 s
100 – 30000
1.0 sec Sets the rate (in seconds/Typical Max Speed) 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 Figures 16 and 17 for the relationship between Full Brake
Rate HS, Full Brake Rate LS, and Low Brake Rate.
Full Brake Rate LS
Full_Brake_Rate_LS_SpdM
0x3820 0x00
0.1 – 30.0 s
100 – 30000
2.0 sec Sets the rate (in seconds/Typical Max Speed) at which the vehicle
slows down from low speeds when full brake is applied, or when
applying full throttle in the opposite direction.
Low Brake Rate
Low_Brake_Rate_SpdM
0x3835 0x00
0.1 – 30.0 s
100 – 30000
4.0 sec Sets the rate (in seconds/Typical Max Speed) at which the
vehicle slows down at all speeds when a small amount of brake
is applied or when applying a small amount of throttle in the
opposite direction.
