Abstract:
1. A controller of a vehicle having a power source, and an automatic transmission, coupled to the power source, that establishes a plurality of gear steps of different gear ratios by selectively engaging a plurality of friction engagement elements, the controller comprising: a control section that controls the power source when the automatic transmission upshift so that a torque-boost control of the power source is executed during a torque phase of the upshift; and a setting section that sets a torque-boost amount for the torque-boost control during the torque phase based on a driver requested output amount, wherein the setting section increases the torque-boost amount as the driver requested output amount increases until the requested output amount exceeds a predetermined value, when the driver requested output amount exceeds the predetermined value, the setting section decreases the torque-boost amount as the requested output amount increases, and wherein a torque obtained by adding the torque-boost amount to a requested torque, which corresponds to the driver requested output amount, is increased as the driver requested output amount increases.
