Abstract
ECU of the motor vehicle controls the driving condition of the engine and the shift stage of the automatic transmission. ECU controls a determination step of determining whether a downshift occurs in the accelerator-on state during the downshift associated with the accelerator-off, and a torque-up step of increasing the torque based on the operation of the electronic control throttle of the engine when the downshift occurs in the accelerator-on state. In the torque-up step, the first throttle torque request amount in the first period before the start of the inertia phase is made smaller than the second throttle torque request amount in the second period after the start of the inertia phase.
Claims8
A control device for a vehicle, for controlling a driving state of an engine and a shift stage of an automatic transmission, wherein:
- the control device controls
- a determination process of determining whether downshifting will occur in a state in which an accelerator is depressed, due to the accelerator being depressed during execution of downshifting in conjunction with the accelerator not being depressed, and
- a torque increasing process in which, when determination is made in the determination process that downshifting will occur in the state in which the accelerator is depressed, torque is increased based on operation of an electronic control throttle of the engine before starting of an inertia phase of the automatic transmission and after starting of the inertia phase;
- and
- in the torque increasing process, a first throttle torque request amount in a first period before starting of the inertia phase is set to be smaller than a second throttle torque request amount in a second period after starting of the inertia phase.
