MALFUNCTION DETECTION APPARATUS AND HYBRID VEHICLE

摘要

An engaging and disengaging controller for controlling the engagement and disengagement of a power transmission path by supplying a working oil of a predetermined pressure to an engaging and disengaging mechanism includes a valve for opening and closing a flow path of the working oil, and an opening/closing detection section which detects an opened or closed state of the valve. A malfunction detection apparatus for the engaging and disengaging controller includes an opening/closing control section for the valve, a time counting section which counts a predetermined time from the start of an opening/closing control, and a malfunction detection section which determines that the engaging and disengaging controller malfunctions in the case where the time counting section ends counting in such a state that the results of a detection by the opening/closing detection section do not coincide with the details of a control executed by the opening/closing control section.

主权项

1. A malfunction detection apparatus for an engaging and disengaging controller that supplies a working oil of a predetermined pressure to an engaging and disengaging mechanism which engages and disengages a power transmission path to control engagement and disengagement of the power transmission path,
wherein the engaging and disengaging controller comprises: a valve for opening and closing a flow path of the working oil to the engaging and disengaging mechanism; and an opening/closing detection section which detects an opened or closed state of the valve, and wherein the malfunction detection apparatus comprises: an opening/closing control section which controls the valve of the engaging and disengaging controller to be opened or closed; a time counting section which counts a predetermined time from a start of an opening/closing control by the opening/closing control section; and a malfunction detection section which determines that the engaging and disengaging controller malfunctions in a case where the time counting section ends counting of the predetermined time in a state that detection results by the opening/closing detection section of the engaging and disengaging controller do not coincide with control details executed by the opening/closing control section.
