Problems solved by technology

[0004] However, after reducing the engagement pressure of the release-side engagement device, which is the engagement device that releases to switch gears, residual pressure may remain due to a delay in response.
If the torque of the driving force source is reduced in this state, there is a possibility that negative torque will be transmitted to the wheel side via the release-side engagement device with a remaining transmission torque capacity.

Abstract

A control device is provided which performs upshift control in a manner suitable to the torque of the drive power source and so as to suppress reductions in torque transmitted to the wheels via a release-side engagement device even if there is still residual pressure in said release-side engagement device. In inertial phase control, torque reduction control is performed on the torque of the drive power source, and the start time of the torque reduction control relative to the execution time of the torque phase control is changed in accordance with at least the torque of the drive power source before shift start.

Description

technical field [0001] The present invention relates to a control device for controlling a vehicle drive device provided with a transmission device on a power transmission path connecting a driving force source and wheels. The transmission device is provided with a plurality of engagement devices. Selectively form a plurality of gears with different gear ratios according to the engaged state. Background technique [0002] Regarding such a control device as described above, for example, a technology described in Patent Document 1 below is known. In the technology described in Patent Document 1, in the upshift control for switching the gear stage of the transmission device to a gear stage with a relatively small gear ratio, the torque phase control is used to control the engagement pressure of the engagement side engagement device to To increase, while maintaining the increased pressure, the torque of the driving force source is decreased to start a rotational change in which...
