Abstract

The invention provides a control device in a hybrid vehicle. Noise or vibration occurring when a parking lock is released can be efficiently reduced in the hybrid vehicle which includes a stepped typetransmission divided into two systems of a shift shaft at an odd shift stage side and a shift shaft at an even shift stage side. A 2-speed stage is selected as a pre-shift stage set when a meshing member (57) is meshed with a parking lock gear (54) and a parking lock mechanism (59) has a parking lock state. The 2-speed driving gear is joined to an output shaft (CS) using a second engagement switching mechanism (83, 84) in a state in which the 2-speed stage is set as the pre-shift stage so that a larger inertial mass can be secured as an inertial mass of the parking lock gear and members joined to the output shaft. Therefore, noise or vibration occurring due to release of the parking lock state of the parking lock mechanism can be efficiently reduced.

Description

technical field [0001] The present invention relates to a hybrid vehicle control device for controlling the operation of a driving source and a gearbox in a hybrid electric vehicle (HEV), which includes an internal combustion engine and an electric motor as a driving source ; and a stepped gearbox, which is divided into two systems: the shift shaft on the odd-numbered shift gear side and the shift shaft on the even-numbered shift gear side. Background technique [0002] Conventionally, there has been a hybrid vehicle including an engine (internal combustion engine) and a motor (electric motor) as drive sources. Some of such hybrid vehicles are provided with a stepped transmission capable of transmitting the driving force of at least one of the internal combustion engine and the electric motor to the drive wheel. [0003] In addition, as a transmission used in a hybrid vehicle as described above, there is, for example, a twin-clutch type transmission, which, as shown in Pat...
