The problem of synthesis of control algorithms for gear shift using electric-hydraulic and electronic devices
摘要
Approaches to the problem of synthesis of control algorithms for gear shift using electric-hydraulic and electronic devices were examined. It is noted that well-timed shift should increase tractor velocity and a “successful” algorithm should not worsen its usability. Possible criteria were analyzed.
