<P>PROBLEM TO BE SOLVED: To change motor rotation control constants for a hybrid vehicle according to whether to prioritize a command follow-up response or prioritize a disturbance suppression response. <P>SOLUTION: If it is determined in S1 that a shift is in progress, because a motor must be speed-controlled to change a transmission input speed quickly to the shift speed, a command follow-up response time constant τm is decreased for a faster response and a disturbance suppression response time constant τh is increased for a slower response in S2 while a gain margin is kept intact. If it is determined in S3 that there is an engine start request and it is determined in S4 that a first clutch is disengaged, because the motor must be increased up to an engine start enabling speed, S2 is executed. If it is determined in S4 that the first clutch is engaged, because the motor speed must be controlled to suppress speed fluctuations after the engine start, the disturbance suppression response time constant τh is decreased for a faster response and the command follow-up response time constant τm is increased for a slower response in S5 while the gain margin is kept at a predetermined value in S5. <P>COPYRIGHT: (C)2008,JPO&INPIT |
