DBW Closed Loop Control - DBW PID Setup

DBW PID Setup

The output control signal is held constant when the Input Signal (Throttle Position) falls within the deadband range of the Target.

This helps reduce steady state error and oscillations.

Typical : 0.2 %TP

If a second DBW servo is used that is of a different type, then the PID can be customized separately.

This enables configuration tables for DBW 2

** Most commonly used when a DBW servo is used for bypassing air for a turbocharged or supercharged vehicle (DBW Air Bleed)

0: OFF

1: ON

DBW Target Filter - Time Constant

Low pass digital filter Time Constant characterizes the speed taken to respond to a step input.

The value entered represents the time (in ms) it takes for the output to reach 63% of the stepped input value.

For example if the step input changed occurred from 0 - 50.0% and the Time Constant was 25ms, the filtered output would reach 31.5% after 25ms.

DBW servo position is controlled in the Torque Management section -> Pedal Demand.
