Title:

機関バルブの駆動制御装置

Document Type and Number:

Japanese Patent JP4281257

Kind Code:

B2

Abstract:

A drive control apparatus and method control driving of an engine valve (10) of an internal combustion engine based on electromagnetic force generated by a certain electromagnet (61, 62). A controller of the apparatus sets a target drive velocity in accordance with a displacement of the engine valve, such that the target drive velocity corresponds to a velocity of the engine valve when there is no engine load. The controller then controls a magnitude of the electromagnetic force by controlling current applied to the electromagnet, depending upon a degree of separation between an actual drive velocity of the engine valve and the target drive velocity, so that the actual drive velocity is made substantially equal to the target drive velocity.
