In Newer automatic transmissions, the valves are managed by solenoids.[fifteen] These solenoids are Pc-controlled, Using the gear collection resolved by a devoted transmission Regulate device (TCU) or sometimes this operate is built-in to the motor Command device (ECU). Modern-day patterns have changed the centrifugal governor having an electronic speed sensor that is definitely used being an enter into the TCU or ECU. Contemporary transmissions also Consider the quantity of load on an engine at any provided time, which is determined from either the throttle place or the quantity of ingestion manifold vacuum.[fifteen]
Utilizing this data and a sophisticated Manage strategy according to fuzzy logic -- a method of programming Command units applying human-sort reasoning -- electronically managed transmissions can do things such as:
The governor can be a clever valve that tells the transmission how briskly the car goes. It's linked to the output, And so the speedier the vehicle moves, the a lot quicker the governor spins.
