A system for controlling a brushless motor includes drive circuitry in communication with the brushless motor and a primary control device in communication with the drive circuitry. The system also includes a secondary control device in communication with the drive circuitry and a multiplexer for selectively providing an output of the primary control device or an output of the secondary control device to the drive circuitry, wherein the output of the primary control device is provided to the drive circuitry when the primary control device is operating normally.

Systems and methods for controlling a brushless motor

The invention provides a control system for an internal combustion engine of a vehicle. The control system includes a sensor controller and an engine controller. The sensor controller includes a first interface configured to be connected to a sensor coupled to the engine, a first one or more components to provide power regulation and electromagnetic compatibility for the sensor controller, a second interface configured to be connected to a local communication bus of the vehicle, and a first processor and memory configurable to provide control and diagnostics of the sensor. The engine controller includes a third interface configured to be connected to the local communication bus, a second one or more components to provide power regulation and electromagnetic compatibility for the engine controller, and a second processor and memory configurable to control at least one aspect of the internal combustion engine based on information from the sensor controller.
