Abstract
A method for operating a vehicle electrical system that is provided for supplying at least one restraint system. In the method, in addition to monitoring the vehicle electrical system voltage, at least one further indicator is monitored as an indicator. A critical supply state of the restraint system is detected by evaluating these indicators and the efficiency of the used DC voltage switching converters is reduced by at least one measure, so that a supply current for at least one restraint system is reduced by the at least one restraint system. A release condition is requested prior to implementing the at least one measure.
Claims12
A method for operating a vehicle electrical system that is provided for supplying at least one restraint system, the method comprising:
- monitoring a voltage of the vehicle electrical system as an indicator and monitoring at least one further indicator;
- detecting a critical supply state of the restraint system by evaluating the indicator and the further indicator;
- and
- reducing an efficiency of used DC voltage switching converters by at least one measure, so that a supply current for the at least one restraint system is reduced by the at least one restraint system;
- wherein a release condition is requested prior to implementing the at least one measure.
An arrangement for operating a restraint system, the arrangement configured to:
- monitor a voltage of the vehicle electrical system as an indicator and monitoring at least one further indicator;
- detect a critical supply state of the restraint system by evaluating the indicator and the further indicator;
- and
- reduce an efficiency of used DC voltage switching converters by at least one measure, so that a supply current for the at least one restraint system is reduced by the at least one restraint system;
- wherein a release condition is requested prior to implementing the at least one measure.
