The invention relates to a method for charging the energy storage cells of an energy storage device, which comprises: n first output connections, wherein n&#x3e;1, for issuing a supply voltage at each of the output connections, a second output connection, wherein a charging device can be connected between the first output connections and the second output connection, and n parallel-connected energy supply branches, which are each coupled between a first output connection and the second output connection, wherein each of the energy supply branches comprises a plurality of series-connected energy storage modules, which each comprise an energy storage cell module comprising at least one energy storage cell, and a coupling device having coupling elements that are designed to selectively connect or bridge the energy storage cell module in the respective energy supply branch. The method according to the invention comprises the following steps: determining a maximum possible charging voltage of a charging apparatus, which provides a charging voltage for the energy storage device; determining the maximum number of the energy storage cell modules of an energy supply branch at which the sum of the output voltages of the energy storage cell modules, which is dependent on the instantaneous charge states of the energy storage cells of all the energy storage cell modules of an energy supply branch, is still lower than the maximum possible charging voltage; and selecting and controlling the coupling elements of energy storage modules of the energy supply branch, such that in each case only the maximum number of energy storage cell modules is coupled into the energy supply branch.

A method and a device for controlling the drive unit of a vehicle are described, which make it possible to suppress faults during controlling. On a first level, at least one first control variable is formed for controlling at least one actuator of the drive unit. On a second level, the correct formation of the at least one first control variable on the first level is verified using at least one selected variable. The at least one first control variable for controlling the at least one actuator is influenced by the second level if the at least one selected variable assumes a predefined value or lies within a predefined range.

Method and device for controlling the drive unit of a vehicle

Described is a system and a method to monitor measuring and control equipment. The occurrence of a malfunction does not immediately lead to the monitoring system entering a secure state, but rather increases the count of a counter. If the count exceeds a certain value, then the monitoring system enters a secure state.

System and method for the monitoring of a measurement and control device

A system for controlling and/or monitoring a control-unit group having at least two control units, a first control unit and at least one second control unit, the first control unit being designed for performing its control function and for monitoring this control function, as well as for monitoring the control function of the at least one second control unit.

In a drive train assembly for a motor vehicle, which includes successively arranged an internal combustion engine, a starter clutch, an electrical machine a drive clutch, and an automatic transmission, preferably an automated manual transmission, a common double clutch positioner is assigned to the two clutches, which enables a selective setting of the applicable status (open or closed) of the clutches by assumption of a corresponding switching position.

Drive train assembly for a motor vehicle, and method for controlling the operation thereof

A method and an apparatus for operating a control unit for controlling operational sequences in a vehicle. When operational sequences are error-free, the control functions of the built-in control unit are partially or completely suppressed. This allows additional functions to be switched in and out, and also allows modification and/or adaptation of data and/or programs that are accessed by the control functions. In the specific operating instance of the application, a further control unit is insertable into the vehicle wiring harness between the first control unit and a sensor arrangement, collection, group or system and an actuator arrangement, collection, group or system. The control functions suppressed in the control unit are then performable by the second control unit. The control unit then performs only the measurement functions and actuation functions The sequence is initiated and controlled by integrated remote-control functions, which are in addition to the normal or other functions. Since the second control unit is accessible and is designed in accordance with its application task, the application of the control unit may be performed using control functions exported therefrom.
