Abstract
A system, apparatus, and method for retrofitting a vehicle are presented. The method relates to a vehicle with a factory-installed first apparatus which communicates with a factory-installed second apparatus through a vehicle data bus using a first message. The method includes electrically disconnecting the vehicle data bus between the first apparatus and the second apparatus and electrically connecting a retrofit apparatus to the vehicle data bus. The method further includes transmitting a second message from the retrofit apparatus to the first apparatus which is indistinguishable from the first message.
Claims20
A method, comprising:
- providing a retrofit apparatus for installation in an existing vehicle, the retrofit apparatus comprising
- a control processor,
- a first CAN bus terminal for electrically connecting the retrofit apparatus to a first factory-installed apparatus,
- a second CAN bus terminal for electrically connecting the retrofit apparatus to a second factory-installed apparatus, and
- a switch operatively connected to and controlled by the control processor, the switch being configured to selectively connect the first CAN bus terminal to the second CAN bus terminal;
- causing an original CAN bus message originating in the second factory-installed apparatus to reach the first factory-installed apparatus by closing the switch to connect the first CAN bus terminal to the second CAN bus terminal;
- causing the original CAN bus message originating in the second factory-installed apparatus to not reach the first factory-installed apparatus by opening the switch to disconnect the first CAN bus terminal from the second CAN bus terminal;
- and
- transmitting a mimicked CAN bus message from the retrofit apparatus to the first factory-installed apparatus.
A method, comprising:
- providing a retrofit apparatus for installation in a vehicle, the retrofit apparatus comprising
- a control processor,
- a first CAN bus terminal for electrically connecting the retrofit apparatus to a first factory-installed apparatus,
- a second CAN bus terminal for electrically connecting the retrofit apparatus to a second factory-installed apparatus, and
- a switch operatively connected to and controlled by the control processor, the switch being configured to selectively connect the first CAN bus terminal to the second CAN bus terminal;
- and
- dividing a vehicle CAN bus into two subnets by opening the switch,
- wherein a first of the two subnets connects the first factory-installed apparatus to the retrofit apparatus through the first CAN bus terminal, and
- wherein a second of the two subnets connects the second factory-installed apparatus to the retrofit apparatus through the second CAN bus terminal.
A method, comprising:
- installing a retrofit apparatus in an existing vehicle, the existing vehicle comprising
- a vehicle CAN bus, and
- a plurality of factory-installed apparatuses connected to the vehicle CAN bus;
- selectively dividing the vehicle CAN bus into two electrically insulated subnets,
- a first of the two electrically insulated subnets being connected to the retrofit apparatus by a first CAN bus terminal and
- a second of the two electrically insulated subnets being connected to the retrofit apparatus by a second CAN bus terminal;
- and
- transmitting a mimicked CAN bus message from the retrofit apparatus on one of the two electrically insulated subnets, the mimicked CAN bus message sharing a common CAN identifier with an original CAN bus message transmitted by one of the plurality of factory-installed apparatuses on another of the two electrically insulated subnets.
