5.1.14 vl_velocity_acceleration (Index: 6048h)

The vl velocity acceleration index specifies the slope of acceleration ramp for RFG. (32bit length) It is generated as the quotient of the delta speed(Sub-index1) and delta time(sub-index2) sub- index.

Sub-index1

= delta speed

(unit: min-1

Minimum unit: 1dig= 1min-1)

Sub-index2

= delta time

(unit: sec

Minimum unit: 1dig= 1sec)

vl_velocity_acceleration = delta_speed / delta_time

This Index is effective only RFG mode.

5.1.15 vl_velocity_deceleration (Index: 6049h)

The vl velocity deceleration index specifies the slope of deceleration ramp for RFG. (32bit length) It is generated as the quotient of the delta speed(Sub-index1) and delta time(sub-index2) sub-

index.

 

 

Sub-index1 = delta speed

(unit: min-1

Minimum unit: 1dig= 1min-1)

Sub-index2 = delta time

(unit: sec

Minimum unit: 1dig= 1sec)

vl_velocity_acceleration = delta_speed / delta_time

This Index is effective only RFG mode.
