摘要:
The invention relates, in particular, to a method for extending the useful life of a rechargeable energy store for use in a motor vehicle, such as for example, a double layer capacitor, a Li-ion store, a Li-ion capacitor or a NiMH store with several storage cells. According to the invention, the useful life of the energy store may be extended whereby the temperature of each storage cell is measured. Should the temperature of a storage cell exceed a reference value for the temperature of the storage cell the storage cell is partially discharged and the voltage thereof thus reduced.

The invention relates to a motor assembly (12) for a motor vehicle, comprising an internal combustion engine (58) that has an exhaust gas purification device (56) and a heat engine (10). The heat engine (10) comprises at least one closed working space (14, 20) that is filled with a gas. A first cylinder (16), in which a first piston (26) is movably mounted in the longitudinal direction (L) between an initial position and an expansion position, and a second cylinder (22), in which a second piston (28) is movably mounted in the longitudinal direction (L) between an initial position and an expansion position, and at least one heating unit (36, 38) for heating the gas in at least one heating region (40, 42) of the working space (14, 20) and at least one cooling unit (30) for cooling the gas in at least one cooling region (32, 34) of the working space (14, 20) are provided. The gas heated in the heating region (40, 42) pushes the first piston (26) from an initial position into an expansion position, and then flows through the overflow line (18, 24) into the cooling region (32, 34) and pushes the second piston (28) into the expansion position. The overflow line (18, 24) leads at least in sections through the exhaust gas purification device (56).
摘要:
At least one weighting value is determined in a manner influenced by a vehicle user. A maximum released power which a predefined electrical consumer of the motor vehicle should receive is determined on the basis of the weighting value. Power consumption of the electrical consumer is controlled on the basis of the maximum released power.

The invention relates to the monitoring and/or control or regulation of the voltage of at least one cell group in a cellular composite of an energy accumulator, in particular an energy accumulator in a vehicle power supply system. The invention is characterized in that a data communication between a central logic and a cellular composite logic is carried out via a rail-line connecting them, voltage levels existing between an on-voltage level or an idle voltage level, superior to a maximum voltage level until which the logic of the cell groups exchanges energy with the rail-line for charging and discharging the cell group, and a data level being superior to the idle level.

The invention relates to a data bus system for motor vehicles with a plurality of electronic stations. Said stations are provided with at least one additional connection in direction towards the data bus connection, said additional connection being designed to transmit a vehicle initial operating signal. In vehicles that are not operated, the additional connection transmits a time interrupt signal that switches on at least one station.

The invention relates to a data bus comprising slave nodes executing functions based on addressed command telegrams of an electronic main control unit which is also connected to said data bus. The command telegrams contain an identification field for addressing the commands whereby a reduced number of identification data is provided for said identification field. All functions which can be executed by the form of slave nodes on the data bus are respectively associated with at least one function number. Each slave node comprises a first non-volatile memory area, wherein the function numbers of the functions, which can be executed by a respective slave node are securely stored. Each slave node comprises a second programmable memory area, wherein identification information provided for the identification field can be stored associated with each function number stored by means of a special command telegram from the electronic main control unit to each function number stored in the first memory area.
