Title:
CONTROLLER FOR FORCASTING THROTTLE OPENING DURING AUTOMATIC RUNNING IN ENGINE TESTING DEVICE
Document Type and Number:
Japanese Patent JP3028433
Kind Code:
B2
Abstract:
PURPOSE: To highly accurately conduct a performance test of an engine, motorcar, etc., by providing an running pattern generator, an operation processing part providing a throttle forecast opening operating part, and a fuzzy correction controlling part.
CONSTITUTION: A revolution N-torque T-throttle opening θ map of an engine E to be tested is prepared to be stored, the set revolution and throttle opening θ1 from a running pattern generator 5 are computed from the map in a throttle forecast opening operating part 1, and the throttle opening corresponding to the angular acceleration of the engine E is operated by a part 2 for operating the acceleration equivalent in a throttle opening. The set revolution, the opening θ1, and a throttle opening θ1 of the angular acceleration are added to it in an adder 3, and the added value is inputted to a throttle amplifier 9. The difference of the set revolution.torque and the real one is controlled as deflection correction in a fuzzy correction controlling part 7, and θ1+θ2+θ3 added in an adder 8 is fed back to a throttle actuator 10 as the set value of the last opening, and the throttle of the engine E is actuated by the amplifier 9.
