CONTROL APPARATUS FOR VEHICULAR POWER TRANSMISSION DEVICE

Japanese Patent JP2017030467

A

PROBLEM TO BE SOLVED: To allow a vehicle to be moved with external force and suppress transmission of extraneous power from a drive source to a drive wheel when a lock state of a power transmission mechanism is manually released, and suppress generation of vehicular vibration or noise due to a sudden start-up of the drive source while the vehicle is moved with the external force.SOLUTION: According to a hybrid controlling-computer 42, a parking lock mechanism 37 includes: a release state determination part 102 for determining whether it is in a release state caused by a manual release mechanism 84; a power transmission cutoff control part 106 for setting a power transmission cutoff state at an automatic speed change part 22 in the case of determining to be the release state; and a drive source activation inhibit part 104 for inhibiting activation of the drive source in the case of determining to be the release state. This makes it possible to cut off the power transmission of a power transmission device 8 at the automatic speed change part 22 and inhibit the activation of the drive source in the case of determining to be the release state, allowing a vehicle to be moved with external force and suppressing transmission of extraneous power from the drive source to the drive wheel.SELECTED DRAWING: Figure 7
