Abstract: If the a rotational speed difference (Ne−Nt) between an engine speed (Ne) and a turbine speed (Nt) when it is determined that a lock-up ON condition (OFF→ON) is satisfied is large, the lock-up clutch is not engaged but torque reduction control is executed to reduce the engine speed (Ne), thus reducing the rotational speed difference (Ne−Nt) (steps ST13 and ST14). Then, once the rotational speed difference (Ne−Nt) has been reduced to the target rotational speed difference (Nslp), the lock-up clutch is engaged (steps ST15 and ST16). In this manner, excessive heating of the friction material of the lock-up clutch is suppressed which increases the longevity of the friction material.

Abstract translation: 如果当确定确定锁定ON状态（OFF→ON）时的发动机转速（Ne）和涡轮转速（Nt）之间的转速差（Ne-Nt）大时，锁定 离合器不接合，而是执行转矩降低控制以降低发动机转速（Ne），从而降低转速差（Ne-Nt）（步骤ST13和ST14）。 然后，一旦转速差（Ne-Nt）已经降低到目标转速差（Nslp），锁止离合器接合（步骤ST15和ST16）。 以这种方式，抑制了锁止离合器的摩擦材料的过度加热，这增加了摩擦材料的寿命。
