Hybrid vehicle control device

摘要

In a hybrid vehicle that is capable both of performing running drive with gear-change being effected by an infinitely variable gear-change mechanism 20 that performs gear-change of the output rotation of an engine E that is capable of temporary stoppage control and also of performing running drive by means of a second motor generator 50, when running using the second motor generator 50 with the engine E temporarily stopped, a forwards/reverse changeover mechanism 10 is released by a forwards/reverse clutch control valve 73. If this forwards/reverse clutch control valve 73 becomes inoperable due to its spool sticking etc, a gear shift inhibitor valve 77 is operated by a gear shift control valve 66 to supply line pressure to the forwards/reverse changeover mechanism 10 through a port of the forwards/reverse clutch control valve 73 in this sticking condition, so that this can thereby be engaged.
