HYBRID VEHICLE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress clutch engagement shock and the protraction of engagement time even if the rotation speed difference between input and output shafts of a clutch is large at a time of switching an EV mode to an HEV mode.SOLUTION: In an EV mode in which an engine is stopped and a clutch CL is disengaged, it is determined whether an absolute value of a subtraction value between an estimated rotational speed of the clutch CL on a continuously variable transmission side and an actual rotational speed of the clutch CL on a driving wheel side is greater than a predetermined rotational speed difference. If it is determined that the absolute value of the subtraction value is greater than the predetermined rotational speed difference, then the engine is restarted even with an operation point in an EV area, and at least one of an engine rotational speed and a gear ratio of the continuously variable transmission is controlled so that a secondary rotational speed exceeds that of an output shaft with the clutch CL disengaged.
