Abstract
A system includes a bus system, such as a LIN bus system. A number of components are connected to the bus system. A first component of the components is configured to detect a direction of a current to detect a location of the first component in the bus system. Each of the components can have a unique address.
Claims24
A method to address components connected to a bus system, the method comprising:
- determining that a test signal is being applied to the bus system;
- and
- determining a location of a first slave component in the bus system by detecting a direction of a current of the test signal through the first slave component.
A system comprising:
- a bus system configured to transport a test signal;
- and
- a plurality of slave components connected to the bus system, wherein a first slave component in the plurality of slave components is configured to detect a direction of a current of the test signal through the first slave component to detect a location of the first slave component on the bus system.
A vehicle comprising:
- a local interconnect network (LIN) bus;
- a plurality of components connected to the local interconnect network (LIN) bus system including at least a first component and a second component, wherein the first component is configured to detect a direction of a current through the first component to determine a location of the first component relative to the second component on the bus system;
- and
- a plurality of vehicle devices, each vehicle device electrically coupled to a respective one of the plurality of components.
1 more element
A method comprising:
- assigning a unique address to each of a plurality of components connected to a bus system, and
- detecting a position of a first component in the plurality of components on the bus system by detecting a direction of a test signal current through the first component.
A system comprising:
- a bus system;
- and
- a means for detecting a location of a component in the bus system by detecting a direction of a current through the component.
