Abstract
A vehicle includes a transmission between an engine and a drive wheel and includes a differential mechanism (planetary gear mechanism) between the engine and an engagement device (transmission). A controller (ECU) included in the vehicle calculates a variation rate in the whole rotation energy of the planetary gear mechanism when it is in the inertia phase of a shift. The ECU increasingly corrects an engine generated power and decreasingly corrects a transmission transfer power when the variation rate is higher than 0. The ECU decreasingly corrects the engine generated power and increasingly correct the transmission transfer power when the variation rate is lower than 0.
Claims14
A vehicle comprising:
- an internal combustion engine configured to generate power for rotating a drive wheel;
- an engagement device provided between the internal combustion engine and the drive wheel, the engagement device being configured to switch into any one of an engaged state, a slipped state and a released state;
- a differential mechanism provided between the internal combustion engine and the engagement device, the differential mechanism having at least three rotating elements including a first rotating element coupled to the internal combustion engine and a second rotating element coupled to the drive wheel via the engagement device;
- and
- a controller configured to control the internal combustion engine and the engagement device, the controller being configured to correct at least one of the power generated by the internal combustion engine and power transmitted by the engagement device on the basis of a variation in rotation energy of the differential mechanism, when the engagement device is in the slipped state or the released state.
