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 8 for 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 8 for 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 Figure 9 for 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 Figure 9 for 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.
