Abstract

A universal vehicle electric power distribution module employs reconfigurable inputs and outputs enabling use of the same hardware across vehicle lines. The module is scalable for ease of expansion and is capable of handling both low current and high current load management on the same module.

Claims

1. A universal vehicle electric power distribution module comprising:

a plurality of reconfigurable module inputs;

a microcontroller coupled for receipt of signals appearing at the reconfigurable module inputs; and

a plurality of reconfigurable module outputs operative, under control of the microcontroller, to selectively couple electrical power to a like plurality of electrical loads in the vehicle.

2. The power distribution module of claim 1 wherein the module inputs and the module outputs are reconfigurable in accordance with contents of a look-up table stored in the microcontroller.

3. The power distribution module of claim 1 further comprising at least one non-reconfigurable input.

4. The power distribution module of claim 1 further comprising at least one non-reconfigurable output.

5. The power distribution module of claim 1 wherein the module is scalable to provide control of additional vehicle electrical loads.

6. The power distribution module of claim 1 wherein the plurality of module outputs includes at least one output controlling delivery of electrical power via pulse width modulation.

7. The power distribution module of claim 1 wherein the plurality of module outputs includes at least one output controlling delivery of electrical power via a power switch.

8. The power distribution module of claim 7 wherein the power switch comprises a relay.

9. The power distribution module of claim 7 wherein the power switch comprises a semiconductor switch.

10. The power distribution module of claim 7 wherein the power switch comprises a programmable power management switch.

11. The power distribution module of claim 1 further comprising a communication bus gateway arrangement.

12. The power distribution module of claim 1 wherein the plurality of module outlets includes first and second outputs each controlling delivery of electrical power to its respective load via respective first and second programmable power management switches, the first power management switch programmed for switching electrical power at a first level, and the second power management switch programmed for switching electrical power at a second level.

13. The power distribution module of claim 1 wherein a first portion of the module outputs deliver power at a first range of current levels and a second portion of the module outputs deliver power at a second range of current levels, and wherein the first portion of module outlets are placed on a first circuit board rated for the first range and the second portion of module outlets are placed on a second circuit board rated for the second range.

14. The power distribution module of claim 13 further comprising a module housing, wherein the first circuit board extends lengthwise transversely to a lengthwise extent of the second circuit board.

15. The power distribution module of claim 14 wherein the first and second circuit boards extend substantially at right angles to each other.
