Cruise Control Actuator: Description and Operation
The actuator motor is operated by signals from the ECU. Acceleration and deceleration signals are transmitted by changes in the Duty Ratio.
Duty Ratio:
The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle, and B is the period of
non-continuity, then.
Duty Ratio = A / A + B * 100 (%)
