Method for controlling converter-fed asynchronous machine for hybrid system used in hybrid vehicle, involves determining end of rotation torque request for machine, and reducing magnetic flux of machine after certain period

摘要

The method involves determining end of rotation torque request for asynchronous machine (14). The magnetic flux of asynchronous machine is reduced after certain period. The length of certain period is defined as probability of renewed occurrence of rotational torque request. Independent claims are included for the following: (1) hybrid system; and (2) hybrid vehicle.
