  • Methods and apparatus for a brake controller autoswitch
    Patent number: 8140235
    Abstract: An autoswitching brake controller is provided for a vehicle having a first brake controller system and a second brake controller system. The controller includes an autoswitch relay coupled to the first brake controller system and the second brake controller system. The autoswitch relay is configured to receive an ignition signal from the first brake controller system. When the second brake controller system is connected, and the ignition signal is received, the autoswitch relay autodetects its presence and disables the first brake controller system, at the same time enabling the second brake controller system.
