A method for monitoring an energy reserve for a safety device for a vehicle includes the task of evaluating a change of a voltage present in the energy reserve between a starting value suitable for operating the safety device and a test voltage value suitable for operating the safety device to monitor the energy reserve.

Method and device for monitoring an energy reserve and safety device for a vehicle

An energy supply unit for supplying a consumer, includes an energy store to supply electric when the consumer is decoupled from an energy supply network. The energy supply unit includes an energy supply controller having an input coupled to the energy store, via a diode, for receiving electric energy and an output for delivering electric energy, and a monitoring unit for outputting a monitoring signal, configured to set the monitoring signal to an active state when an output voltage between the output and a reference potential is lower/greater than a predefined activation threshold value, the monitoring unit configured, when an excessively low input voltage is identified between the input and reference potential of the controller, especially paired with an excessively low output voltage, the monitoring signal is switched to the inactive state when the input voltage is above a reset threshold and the output voltage is within the monitoring band.

An integrated regulator, in particular a voltage regulator, for a personal protection arrangement in a vehicle, includes a regulating element that converts an input signal into an output signal having a defined value, and a control application circuit that applies control to the regulating element to generate the output signal having the defined value. The control application circuit outputs the output signal via the regulating element with at least two different selectable values as a function of a specifying signal, such that for selection of the value of the output signal, a configuration circuit receives at least one configuration signal and, as a function of a configuration ascertained in the context of evaluation, selects one of at least two different specifying signals and applies it to the control application circuit to output the output signal having the selected value.

A device for the voltage supply of an occupant protection system in a motor vehicle having a switching unit and a voltage supply unit, which supplies an operating voltage to the occupant protection system, the switching unit providing a supply voltage to the voltage supply unit when the supply voltage exceeds a predefined threshold value voltage level. A configuration unit is also provided which provides various reference voltage levels for the switching unit as threshold value voltage levels.

A device for monitoring a voltage supply for a vehicle system includes a self-diagnostic function which evaluates a logic state of the comparison signal which is output by a comparison device as a function of an input signal, and checks whether a reset signal which corresponds to the output comparison signal is generatable. The self-diagnostic function recognizes a malfunction of the comparison device when the evaluated logic state of the comparison signal does not match an expected logic state. The self-diagnostic function recognizes a malfunction of the reset device when the checked logic state of the reset signal does not match an expected logic state.

In a control device and a method for operating a safety system for a vehicle, a step-up converter is fashioned as a switching converter which converts an input voltage derived from a vehicle battery voltage into a higher charge voltage at its output. In addition, at least one energy reserve storage device is provided that is charged by the charge voltage for the operation of the safety system in an autarkic mode. Between the step-up converter and the at least one energy reserve storage device there is connected a charge current source that is programmable during operation and that defines a charge current for the at least one energy reserve storage device as a function of its programming.

A control unit and a method for operating a safety system for a vehicle are proposed. A step-up converter configured as a switching converter is provided. The step-up converter converts an input voltage, which is derived from a vehicle battery voltage, into a higher charging voltage at its output. In addition, at least one energy reserve storage is provided which is charged via the charging voltage for operating the safety system in the case of autonomous operation. At least one step-down converter is operated inversely with respect to the step-up converter, the at least one step-down converter converting down the charging voltage or a voltage which is output by the at least one energy reserve storage.

A device is described for charging an electrical energy storage device, which has an active current-limiting device in a main current path in order to limit a supply current to a predefined maximum current. A voltage transformer device is situated downstream from the current-limiting device for raising the potential of the electrical energy storage device over a supply potential.

Device and method for charging an electrical energy storage device

In a method of monitoring a voltage supply of a control unit in a motor vehicle, a supply module which provides the voltages is connected to the components of the control unit via a RESET line and the RESET line is tested every time the control unit is started or all monitoring limits of the supply module show no fault again after the faults of the monitored voltages have been filtered. This test occurs by forced periodic pulses which are generated on the basis of a shift in the limits of the monitoring bands of the supply voltages. The reference voltages VREGUL and VREF are kept independent of each other here in order to prevent system perturbations.
