Assignee: ATLIS MOTOR VEHICLES, INC.
Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A vehicle comprising:
a plurality of vehicle systems, each vehicle system adapted to perform a function of the vehicle;
a plurality of system controllers, each system controller adapted to be connected to one vehicle system respectively whereby each system controller corresponds to one vehicle system respectively, each system controller adapted to generate a first plurality of control signals respectively, each system controller is adapted to provide the first plurality of control signals respectively to its corresponding vehicle system to control an operation of its corresponding vehicle system, each system controller further adapted to generate a second plurality of control signals to control an operation of one or more other vehicle systems; and
a control bus adapted to be connected to each vehicle system of the plurality of vehicle systems, the control bus further adapted to be connected to one or more system controllers of the plurality of system controllers, the control bus adapted to transport the second plurality of control signals from one system controller to one or more other vehicle systems of the plurality of vehicle systems; wherein:
each system controller of the plurality of system controllers includes a tri-state buffer respectively for connecting each system controller respectively to the control bus;
while all system controllers are functional, each system controller generates and provides the first plurality of control signals respectively to its respective vehicle system and the tri-state buffer respectively for each system controller is placed in a high impedance condition whereby the plurality of system controllers cannot access the control bus; and
responsive to a failure of a first system controller, the tri-state buffer of a second system controller is placed in a low impedance condition, the second system controller generates and provides the second plurality of control signals to the vehicle system corresponding to the first system controller via the tri-state buffer and the control bus, whereby the second plurality of control signals control the operation of the vehicle system corresponding to the first system controller.
