摘要:
A drive device for a vehicle having a combustion engine and a multistage manual transmission having first and second sub-transmissions, each of which has a separate input shaft. A first input shaft of the first sub-transmission couples, via a first clutch, the combustion engine or is assigned an electrical machine. A second input shaft of a second sub-transmission couples, via a second clutch, the combustion engine. The first input shaft is additionally assigned a start-up element having at least one hydrodynamic transfer element, which has first and second functional wheels which together form a working chamber. The working chamber can be filled with fluid in order to generate a hydrodynamic transfer torque such that at least one start-up function, affecting the first sub-transmission, can carried out by way of the start-up element.

A control method for a vehicle transmission includes, in a TCU, receiving the rpm of an engine from an rpm sensor and determining whether to perform shifting of gears depending on the received rpm, when the shifting of gears is determined, allowing the TCU to control an ECU to cut off fuel supplied to the engine combustion chamber and to release a clutch connecting the engine and the transmission, after the control action is performed, monitoring a change in pressure of engine cylinders and allowing engine braking action to be activated, and when the rpm is reduced to a predefined value or less after the engine braking action, performing a shifting action.

摘要:
In a control apparatus for a vehicle, when a coast downshifting is performed in response to a downshifting command from a vehicle operator during braking operation under the fuel cut control, the braking force of the wheel brake is increased so as to increase the deceleration. This makes it possible to achieve a predetermined deceleration with a good response to the deceleration request of the vehicle operator represented by the downshifting command. The control apparatus is structured to decrease the braking force of the wheel brake such that the increase in the engine braking force is offset by the inertia caused by the rise in the engine speed resulting from downshifting upon the coast downshifting due to the vehicle speed increase. The control apparatus for the vehicle, thus, reduces the shock caused by the sharp increase in the engine braking force.
