HYBRID VEHICLE AND CONTROL METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a hybrid vehicle and a control method therefor, which enable prevention of rapid increase in the rotation speed of an internal combustion engine occurring when a lockup clutch is released and suppression of lockup clutch wearing caused by the clutch repeating a released state and an engaged state, thus improving durability.SOLUTION: In a case where a motor-generator 5 is capable of providing a power transmission mechanism 4 with drive force when output torque Te of an engine 3 is reduced to be less than target output torque Te', a control apparatus 20 executes power drive control C30 for power-driving the motor-generator 5 to execute engagement maintenance control C40 for maintaining an engaged state instead of releasing a lockup clutch 10d.
