Abstract
In a vehicle with a power distributor and a control unit, the power distributor includes a bistable relay with at least one coil. The bistable relay can be set to first and second switching states. The bistable relay has an integrated circuit, wherein a control unit activates the integrated circuit by way of a control line and defines one of the two switching states via a control signal. The control unit applies a first control voltage or a second control voltage to the control line, wherein the first control voltage corresponds to the first switching state, and the second control voltage corresponds to the second switching state. The integrated circuit switches a current pulse through the coil in order to set the bistable relay to the switching state defined by the control unit.
Claims14
A vehicle, comprising:
- a control unit;
- a power distributor comprising a bistable relay having at least one coil;
- wherein the bistable relay comprises an integrated circuit, the bistable relay being settable to first and second switching states;
- wherein the control unit is operatively configured to activate the integrated circuit of the bistable relay via a single control line, the control unit defining one of the first and second switching states by way of a control signal, wherein the control unit is electrically connected to the bistable relay only by way of the single control line;
- wherein the control unit applies a first control voltage or a second control voltage as the control signal to the single control line, the first control voltage corresponding to the first switching state and the second control voltage corresponding to the second switching state;
- and
- wherein the integrated circuit is operatively configured to switch a current pulse through the at least one coil in order to set the bistable relay to the switching state defined by the control unit.
