The present invention relates to a shift sequence control to coordinate shifting, which corresponds to changes of constellations in a transmission. A change of the constellations yields a change of the force transfer of the transmission. The sequence of shifting takes place program-controlled and is subdivided into phases (0, 1, 2, 3, 4, 5, 6, 7). The sequence includes the driving of a plurality of actuating elements and each of the phases is assigned at least one type of drive for at least one actuating element. According to the invention, it is provided that the phases (0, 1, 2, 3, 4, 5, 6, 7) can be configured without changing the program. Furthermore, the present invention relates to a method for coordinating shifting sequences.

Shifting process control and method for coordinating shifting processes

A pressure control for the program-controlled drive of at least one pressure actuating member influences the hydraulic constellation in a transmission via the pressure (p). The program-controlled drive takes place via changes of states (z; Z, Z, Z, Z, Z, Z, Z, Z) from current states (z(t)) to subsequent states (z(t+1)) and that the states (z; Z, Z, Z, Z, Z, Z, Z, Z) are all configurable without change of program. A method is provided for the program-controlled drive of at least one pressure actuating member.

The method serves for the shift sequence control of a continuous automatic transmission, especially of a motor vehicle, having gear-stage switchover. The transmission ratio of the automatic transmission is adjustable within a set gear stage by means of an adjusting unit. Here, it is provided that a coordinated, data-dependent control of the gear stage switchover and the continuous transmission ratio adjustment takes place with the aid of a common shift sequence control system.

A method is provided for starting an internal combustion engine which includes a starter, an ignition, pressure store and injection valves for injecting fuel directly into the engine. An electrical high pressure pump is connected to an electrical fuel pump downstream thereof for pumping the fuel into the pressure store. The electrical fuel pump and the electrical high pressure pump are first switched on together with the ignition in order to generate a pressure in the pressure store adequate for the injection of the fuel. Then, the starter is switched on after a time duration after the electric fuel pump and the electrical high pressure fuel pump are switched on.

Fuel supply system for an internal combustion engine, especially a motor vehicle

An internal combustion engine ( ) especially for a motor vehicle is described. The engine is provided with an injection valve ( ) with which the fuel is injected for a combustion, can be injected directly into a combustion chamber ( ) of a cylinder ( ) in a first operating mode during an induction phase and in a second operating mode during a compression phase. A spark plug ( ) is provided with which the fuel, which is injected in both operating modes, is ignited. A catalytic converter ( ) is provided for storing nitrous oxides arising during the combustion. With a control apparatus ( ), the operating variables of the engine ( ) can be controlled (open-loop and/or closed-loop) in both operating modes. A gear change into another gear stage and a switchover into the first operating mode can be carried out approximately simultaneously by the control apparatus ( ). The switchover into the first operating mode is provided for discharging the nitrous oxides stored in the catalytic converter ( ).

A method for simulating control functions of a control device, in which a control program code for execution of control functions is stored in a first memory area of a memory belonging to the control device, the control program code including one or more control program code modules for the control functions, and containing at least one switching device for switching over from a control program code module SPCM to a simulation program code module. At least one simulation program code module for one or more test control functions is made available in a second memory area of the memory. The switching devices switch over from the control program code module to a pertinent simulation program code module stored in the second memory area. The control program code is then processed, the simulation program code module being executed, via the switched-over switching device, instead of the control program code module.

The invention is directed to a control arrangement for a direct injected gasoline engine. A sensor detects at least one operating variable of the engine and an actuator adjusts the air supplied to the engine. A control unit switches the engine between a stratified charge mode of operation and a homogeneous mode of operation in dependence upon the one operating variable of the engine. The control unit drives the actuator so as to cause the actuator to undergo a defined displacement when the control unit switches between the modes of operation so that the torque of the engine is essentially the same before and after the switchover between the modes of operation.
